Does Hedging Success Matter? An Empirical Study Of Jet Fuel Hedging In The U.S. Airline Industry, Brian Hornung

USF Tampa Graduate Theses and Dissertations

Airlines commonly employ hedging as a risk management strategy to protect themselves against sudden, unpredictable increases in the price of jet fuel. In a seminal paper by Carter, Rogers, and Simkins (2006), it is established that jet fuel hedging by airlines increases the firm value of the airline. This dissertation replicates their study using an expanded dataset over a greater period of time. This study finds a smaller “hedging premium” than Carter, Rogers, and Simkins (2006). It is shown that the leasing of aircraft plays an important role in the relationship between the hedging premium and capital expenditures.

The measure …

ABSTRACT

The focus of this study was to explore, through the lens of Pierre Bourdieu’s constructs of habitus, field, and capital, the post-secondary experiences of foster youth who transitioned out of the Louisiana foster care system. Specifically, this comparable multiple case study sought out to understand how cultural, social, and financial capital influenced the post-secondary educational outcomes of foster care alumni as compared to first-generation and continuing-generation students. Seven common themes emerged from the study: predisposing factors towards post-secondary education; values, knowledge, and skills associated with post-secondary education attainment; informal and formal social networks facilitating post-secondary support; financial resources addressing …

Role-Differentiated Bimanual Manipulations Efficiency: The Difference In Speed For Rdbms Based On Age, Toy-Type, And Infant Hand Preference, Sarai Mikal Cortina

Theses and Dissertations

Role-differentiated bimanual manipulation (RDBM) is a complex behavior requiring the complementary movement of two hands to achieve a common goal. The current study investigated the relation of RDBM efficiency (speed to complete a successful RDBM) with hand preference, toy type (simple/difficult), age, and hand used to perform the RDBM. This study observed 46 infants between the ages of 9 to 14 months, each with a different hand preference category. Changes in RDBM efficiency across time were examined across different hand preference groups for RDBMs performed on simple toys using the right hand. The analysis revealed that early-right preference infants had …

Anxiety In Presentational And Interpersonal Oral Tasks Face-To-Face And Online, Angus Leydic

Theses and Dissertations

Within computer mediated communication, there has been a large focus on synchronous and asynchronous text-based methods and how it can be used to help oral proficiency and lower anxiety but very few studies have looked at how audio computer mediated communicative tasks affect anxiety. This study sets out to seek whether using audio computer mediated communication helps lower anxiety for beginner Spanish language students. In order to do so, three research questions are suggested: (1) How do participants’ levels of FLA differ between presentational oral tasks completed in the classroom and presentational tasks completed in an online interface? (2) How …

The Russo-Japanese War: Origins And Implications, Benjamin E. Mainardi

James Madison Undergraduate Research Journal (JMURJ)

The 1904-1905 Russo-Japanese War was the first major conflict of the twentieth century and a turning point in the balance of power in East Asia. In the short term, Russia’s defeat helped precipitate the 1905 Russian Revolution and the 1917 October Revolution. More broadly, the aftermath of the war informed Japan’s imperial ambitions in Manchuria—the early stages of World War II in Asia during the 1930s—and continuing Russo-Japanese enmity over Sakhalin Island and the Kuril Island chain. Studying this historical conflict in terms of international relations provides valuable insights into the nature of the conflict and how the past continues …

Comparing The Accuracy Of Close-Range Photogrammetry To Microct Scanning Via Surface Deviation Analysis Of 3d Digital Models Of Hominin Molars, Margaret J. Furtner

LSU Master's Theses

The purpose of this study is to assess whether close-range photogrammetry is a viable alternative to microCT scanning for the construction of 3D models of isolated teeth. Photogrammetric scanning is more cost-effective and less time-consuming than CT scanning, and in paleoanthropological contexts eliminates the possibility of exposing fossils to doses of radiation that affect ESR dating. Samples of fossil (Homo naledi), archaeological, and contemporary human molars were scanned via microCT scanning and close-range photogrammetric scanning. The photogrammetric scans included 96 digital images per tooth which were used to construct a 3D triangular mesh. The resulting models of the tooth crowns …

A Partial Presence Is No Presence: Public History Institutions And The Danger Of Social Media, Alex Warren

Graduate Student Research Symposium

243.6 million people use social media in the United States alone: that is roughly ¾ of the population.[1] This massive audience gives the perception that, especially for smaller public history organizations, it is a simple and effective tool to reach their audiences. But this may not be the case. Although social media provides an opportunity to put forth information to a wide public audience in a way that would otherwise be near impossible for many non-profit organizations, the reality of a successful social media presence provides potentially catastrophic results for an unprepared organization.

Effective social media use requires consideration …

Models Of Secure Software Enforcement And Development, Hernan M. Palombo

USF Tampa Graduate Theses and Dissertations

Computer Security has been a pressing issue that affects our society in multiple ways. Although a plethora of security solutions have been proposed and implemented throughout the years, security continues to be a problem for at least two important reasons, (1) implementations of runtime enforcement mechanisms have not been modeled rigorously and thus may not be enforcing the policies that are expected to enforce, and (2) there are conflicting tensions in the software development process that hinder the implementation and maintenance of secure software. To investigate these issues, this dissertation is divided into two parts.

The first part of this …

Parent Perceptions Of The Acceptability, Effectiveness, And Experience Of Engaging In The Group Stepping Stones Triple P Intervention For Parents Of Children With Disabilities, Tara B. Delach

USF Tampa Graduate Theses and Dissertations

The challenges associated with parenting are often compounded for parents of children with developmental disabilities. Children with developmental disabilities are at increased risk for exhibiting mental health concerns and challenging behavior compared to their typically developing peers. Parents who are raising a child with a disability tend to experience increased demands, higher levels of stress, and greater challenges associated with the physical, emotional, and behavioral needs of their children than do parents of typically developing children.

Winning “Americans” For Jesus?: Second-Generation, Racial Ideology, And The Future Of The Brazilian Evangelical Church In The U.S., Rodrigo Otavio Serrao Santana De Jesus

USF Tampa Graduate Theses and Dissertations

Beginning in the mid-1980s, a significant number of Brazilians began to leave their country due to economic stagnation, affecting the population and the middle class in particular. This event became known as the “Brazilian Diaspora” and was characterized by a type of labor diaspora that made scholars identify Brazilian immigrants as economic refugees. In the United States, churches have been one of the most important institutions to receive and socialize Brazilians. Considering that a new generation of U.S. born Brazilian Americans emerged, this dissertation provides one of the first studies to investigate the dynamics of a second-generation Brazilian church.

Using Historical Information And Data To Strengthen Planning For Environmental Protection And Management At Everglades National Park, South Florida, George Atisa

Public Affairs and Security Studies Faculty Publications

The early environmental conditions in many national parks fit the favorable description given to Everglades National Park (ENP) at the time of its founding that the park’s wilderness and ecological resources were “superlative in value.” With the understanding that wilderness does not mean complete human exclusion, this study examines the possibilities, interests, and difficulties associated with establishing the historical superlative state of the park’s resources as a target for current restoration efforts. The focus is specifically on ENP, as the park’s existence was considered justified only if its superlative and pristine wilderness conditions could be retained in the future. Data …

The Security Apparatus, Federal Magistrate Courts, And Detention Centers As Simulacra: The Effects Of Trump’S Zero Tolerance Policy On Migrants And Refugees In The Rio Grande Valley, Terence Garrett

Political Science Faculty Publications

Trump’s DHS implemented the Zero Tolerance policy from April 6 to June 24, 2018. Refugees, prevented from crossing the midpoints of bridges by Customs and Border Protection agents, crossed the Rio Grande to ask for asylum, were denied, and forced to cross at places deemed illegal by law. This resulted in misdemeanor violations for unlawful entry and fleeing immigration checkpoints. The policy initiative centered on the separation of children from their migrant parents—refugees fleeing from the northern triangle countries: El Salvador, Honduras, and Guatemala. Adult migrants were sent to prisons and holding facilities, brought before a magistrate to plead guilty, …

Through interviews with B …

Learning Set Representations For Lwir In-Scene Atmospheric Compensation, Nicholas M. Westing, Kevin C. Gross, Brett J. Borghetti, Jacob A. Martin, Joseph Meola

Faculty Publications

Atmospheric compensation of long-wave infrared (LWIR) hyperspectral imagery is investigated in this article using set representations learned by a neural network. This approach relies on synthetic at-sensor radiance data derived from collected radiosondes and a diverse database of measured emissivity spectra sampled at a range of surface temperatures. The network loss function relies on LWIR radiative transfer equations to update model parameters. Atmospheric predictions are made on a set of diverse pixels extracted from the scene, without knowledge of blackbody pixels or pixel temperatures. The network architecture utilizes permutation-invariant layers to predict a set representation, similar to the work performed …

Measuring The Multidimensional Construct Of Pornography: A Long And Short Version Of The Pornography Usage Measure, Dean M. Busby, Brian J. Willoughby, Hsin-Yao Chiu, Joseph A. Olsen

Faculty Publications

With the increase in the availability and usage of pornography, the research on the effects of pornography has also increased. This research has uncovered several controversies in the field regarding how pornography usage influences attitudes, sexual behaviors, and relationships. However, many of the measures of pornography are problematic as there is often little reliability and validity information for them and it is not clear that participants in these research studies are referring to the same types of materials when they answer pornography usage questions. Consequently, many of the research findings are suspect and it is crucial to develop reliable and …

Identity Centrality's Influence On The Relation Between Disclosure And Mental Health Stigma, Samantha Ege

Theses and Dissertations

Past research has shown that disclosing one’s mental illness to another individual has reduced one’s feelings of self-stigma. However, there are gaps concerning the reasons why the act of disclosing for some decreases self-stigma, whereas the act of disclosing increases self-stigma in others. This study purported to fill this gap by investigating the influence of identity centrality on the relation between disclosure and self-stigma and positive regard’s moderation of identity centrality’s influence. Students from Illinois State University were recruited through e-mail and SONA and were asked to complete a series of questionnaires regarding distress, disclosure, identity, positive affect, and self-stigma. …

Physical Therapists Perceptions Of Patient Adherence And Strategies For Facilitating Motivation, Teadora Markovski

Theses and Dissertations

Physical therapists (PTs) are professionally required to undertake a comprehensive examination of their patients and provide consultation within their expertise, yet also have the task to motivate patients to adhere to therapy.

Crisis Communications: Facing Covid-19 Together Could Lead To Positive Psychological Growth, Lowri Dowthwaite

Social Space

Although news reports of hoarding, and panic-buying might make it hard to believe, research shows that natural disasters, like the COVID-19 pandemic, can actually bring out the best in people. Although times of significant threat or crisis can cause post-traumatic stress, research shows that so-called “adversarial growth” is just as common as a response. This is our capacity to not only overcome a crisis, but to actually grow stronger, wiser and more resilient.
