Investigating Sound And Gear Modification As A Means Of Reducing Shark Bycatch, Eduardo Josue Rangel

Electronic Theses and Dissertations

Sharks are unintentionally captured during commercial fishing operations and discarded, known as bycatch. Sharks captured in this manner have high mortality rates resulting in hundreds of millions of sharks killed annually. Longline operations have the highest instances of bycatch. In this study, two methods for reducing shark bycatch were investigated. A simple gear modification on longline leaders was tested by substituting monofilament (mono) leaders with ultra-high-molecular-weight polyethylene (spectra) leaders. A recording of thunder was tested during longline fishing for a deterrent effect. The experiments were conducted simultaneously on a 915 m longline with 50 leaders with each leader alternating between …

Repetitively Counting Sheep: Sleep As A Moderator Of Executive Function Performance On Obsessive-Compulsive Symptoms, Brittany S. Sapp

Electronic Theses and Dissertations

As a leading cause of disability worldwide, Obsessive-Compulsive Disorder (OCD) is associated with considerable costs on individual and economic levels. According to a U.S. national comorbidity survey, approximately 28% of individuals experience obsessive-compulsive (OC) symptoms in their lifetime. As with most psychiatric disorders, sleep disturbances are highly prevalent in individuals with OCD and have been linked to greater severity of OC symptoms and poorer treatment response. Similarly, deficient executive functioning (EF) has been demonstrated in OCD, with research evidencing a connection between EF impairment and OCD course, symptom severity, and treatment response. Sleep difficulties are also implicated in impaired EF, …

Exploratory Analysis Of Effects Of Data On Adversarial Perturbations, Hamza Ali Zafar

Electronic Theses and Dissertations

In recent years, the amount of data being produced has increased tremendously. This data has allowed us to create and train machine learning models that are being used nowadays. Though these models have proven to be very effective in classification and regression problems, they do have a vulnerability. This vulnerability is exploited by adding adversarial perturbations to the original data or in the deployed model. These adversarial attacks are done by making minute changes to the data to confuse the machine learning model. This can lead to models’ misrepresentation and drop the accuracy. For the span of this paper, I …

Optimizing Exposure For Contamination Ocd: What Happens When Digust Is Specifically Targeted?, Molly E. Wickenhauser

Electronic Theses and Dissertations

Disgust is a basic emotion with distinct subjective, physiological, cognitive, and behavioral processes that include revulsion, parasympathetic nervous system activity, contamination-specific appraisals, and disease-avoidance behaviors. Pathological disgust responses may contribute to the development and maintenance of anxiety-related psychopathology, particularly spider and blood-injection-injury phobias, health anxiety, post-traumatic stress disorder, and obsessive-compulsive disorder (OCD). Evidence-based treatments for these disorders were developed based on theories of fear and anxiety and involve exposure-based cognitive-behavior therapy. However, traditional exposure methods appear to be less effective at achieving habituation to disgust compared to fear and anxiety. Additionally, individuals with elevated disgust and primary contagion concerns seem …

Post-Newtonian Dynamics Of Eccentric, Spinning Binary Black Holes And The Associated Gravitational Waveforms, Sashwat Tanay

Electronic Theses and Dissertations

In 2015, the gravitational wave (GW) era of astronomy began. The binary black hole (BBH) system being the primary source of GWs, are at the center stage of GW astronomy. The matched-filtering method of detection of GWs requires accurate modeling of the BBH system and the associated GWs. With the increasing sensitivity of the GW detectors, we need to push our GW models to even higher accuracy in the future. There is also a need to make these models as fast as possible to implement so as to allow for hundreds of detections in a year. This is where the …

Chemical Authentication And Speciation Of Salvia Botanicals: An Investigation Utilizing Gc/Q-Tof And Chemometrics, Joseph Lee, Mei Wang, Jianping Zhao, Bharathi Avula

Faculty and Student Publications

Members of the genus Salvia are used as culinary herbs and are prized for their purported medicinal attributes. Since physiological effects can vary widely between species of Salvia, it is of great importance to accurately identify botanical material to ensure safety for consumers. In the present study, an in-depth chemical investigation is performed utilizing GC/Q-ToF combined with chemometrics. Twenty-four authentic plant samples representing five commonly used Salvia species, viz. S. apiana, S. divinorum, S. mellifera, S. miltiorrhiza, and S. officinalis, are analyzed using a GC/Q-ToF technique. High-resolution spectral data are employed to construct a sample class prediction (SCP) model followed …

Search For The Radiative Penguin Decays B0 → Ks0 Ks0 Γ In The Belle Experiment, H. B. Jeon, K. H. Kang, H. Park, I. Adachi, H. Aihara, S. Al Said, D. M. Asner, H. Atmacan, T. Aushev, R. Ayad, V. Babu, S. Bahinipati, P. Behera, K. Belous, J. Bennett, F. Bernlochner, M. Bessner, V. Bhardwaj, B. Bhuyan

Faculty and Student Publications

We report results from the first search for the rare penguin-dominated decay mode B0→KS0KS0γ, which can result from the production of tensor mesons f(1270) and f′(1525) in association with a photon. The search uses the full data sample of 772×106 BB¯ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No statistically significant signals are observed in the KS0KS0 invariant mass range 1 GeV/c2

Search For Z′ →Μ+Μ- In The Lμ-Lτ Gauge-Symmetric Model At Belle, T. Czank, I. Jaegle, A. Ishikawa, I. Adachi, K. Adamczyk, H. Aihara, D. M. Asner, T. Aushev, R. Ayad, V. Babu, S. Bahinipati, P. Behera, J. Bennett, F. Bernlochner, M. Bessner, V. Bhardwaj, B. Bhuyan, T. Bilka, J. Biswal

Faculty and Student Publications

We search for a new gauge boson Z′ that couples only to heavy leptons and their corresponding neutrinos in the process e+e-→Z′(→μ+μ-)μ+μ-, using a 643 fb-1 data sample collected by the Belle experiment at or near the ϒ(1S,2S,3S,4S,5S) resonances at the KEKB collider. While previous searches for Z′ performed a data-based estimation of the initial state radiation effect, our search for the Z′ is the first to include effects due to initial state radiation in the signal simulated samples that were used in estimating the detection efficiency. No signal is observed in the Z′ mass range of 0.212-10 GeV/c2, and …

B ¯ →D (∗)ℓ X ¯ Decays In Effective Field Theory With Massive Right-Handed Neutrinos, Alakabha Datta, Hongkai Liu, Danny Marfatia

Faculty and Student Publications

We calculate the complete differential decay distributions for the B meson decays, B¯→D(∗)ℓX¯, to a massive right-handed (RH) neutrino in the low-energy effective field theory (LEFT) framework. We find that a massive RH neutrino does not introduce any new angular structures compared to the massless case, but can cause significant distortions in angular observables. We study the phenomenology of low-energy four-fermion operators permitted by the standard model effective field theory (SMEFT) extended with RH neutrinos (SMNEFT). We show that to explain the positive value of the difference in forward-backward asymmetries, ΔAFBAFBμ-AFBe, tentatively inferred from Belle data, the RH neutrino must …

Exploring The Impact Of A Brief Counseling Intervention For Improving Mental Health Factors And Learning Strategies Among College Students At An Hsi, James Ikonomopoulos, Kristopher Garza, Javier Cavazos Vela

Journal of Academic Underperformance

Abstract

This study evaluated a counseling intervention called the University Turn Around Program (U-Turn) for college students experiencing mental health issues and low academic performance. Social Anxiety, Hostility, and Alcohol Use were measured on the CCAPS-34, and Attitude, Information Processing, Selecting Main Ideas, Test Strategies, and Using Academic Resources were measured on the LASSI-3. Paired samples t-tests revealed improvement for each measure (d = 0.45 to 1.09) supporting the U-Turn program’s inclusion in university counseling centers.

The Effectiveness Of Developmental Academic Advising As A Retention Intervention For First-Generation Community College Students, Valarie A. Morgan, Mary Bess Pannel

Journal of Academic Underperformance

Student retention is a primary concern for community colleges since retention rates at the community college are unquestionably lower than retention rates at four-year institutions. First-generation college students are a high-risk student group of particular concern, because they make up over thirty percent of the undergraduate population and are two times more likely to exit college at the end of the first year of enrollment when compared to students whose parent or parents have a bachelor’s degree. The results of this study indicate that neither prescriptive advising nor developmental advising made a significant difference in student retention or graduation rates …

Burl Cain, Angola, And Parchman: The National Institution Of Slavery, Cameron Dougherty

Venture: The University of Mississippi Undergraduate Research Journal

Former warden of the Louisiana State Penitentiary and current commissioner of the Mississippi Department of Corrections Burl Cain’s career has drawn national attention for his supposed heraldry of penal reform. Having declared himself to be fulfilling a divinely mandated mission, Cain has frequently cited his criteria of a “good prison: good playing, good praying, good food and good medicine.”1 This article seeks to critically examine these criteria as they relate to Cain’s tenures in both Louisiana and Mississippi while answering the following question: what is the human impact of Burl Cain’s approach to wardency? Despite his focus on the provision …

Anxiety Symptoms Among Extension Professionals' During The Covid-19 Pandemic With The Gad-2, Glenn D. Israel, Colleen E. Gariton, Harsha E. James

Journal of Rural Social Sciences

According to the National Institute of Mental Health, anxiety disorders are a common mental health disorder but often remain undetected and undertreated. During the COVID-19 pandemic, Extension professionals have worked hard to address emerging issues that communities face, possibly impacting the amount of anxiety they experience. This study determined the prevalence of anxiety symptoms among Extension professionals in the United States. Participants from 24 states completed a survey containing the Generalized Anxiety Disorder 2-item (GAD-2) screener. Almost one-quarter of Extension professionals had a GAD-2 score greater than three, an indicator of anxiety with a possibility of generalized anxiety disorder, which …

Implications Of Covid-19 Mitigation Policies On Recreational Trail Users: Exploring Antecedents To Physical Distancing On Trails Across The Rural-Urban Continuum, Christopher J. Wynveen, Ingrid Schneider, Deonne Vanderwoude, Taylor Stein, Heather Gibson, Kim Shinew, William Hendricks, Megha Budruk

Journal of Rural Social Sciences

The COVID-19 pandemic and subsequent travel restrictions led to a worldwide increase in greenspace use. The U.S. Centers for Disease Control and Prevention encouraged policies including physical distancing and COVID-related signage. However, the extent to which these policies influenced behavior is unknown. To fill this gap, we report on a 2020 observational study at 14 trails across six U.S. states framed within a social-ecological model. Behavioral observations of 8,093 groups assessed compliance rates with infection-mitigation behaviors. Additionally, we noted the presence of COVID-related signs, the days between the observation and stay-at-home order start date, the setting (i.e., urban, suburban, and …

Rural-Urban And Within-Rural Differences In Covid-19 Mortality Rates, Yue Sun, Kent Jason G. Cheng, Shannon M. Monnat

Journal of Rural Social Sciences

Since late-2020, COVID-19 mortality rates have been higher in rural than in urban America, but there has also been substantial within-rural heterogeneity. Using CDC data, we compare COVID-19 mortality rates across the rural-urban continuum as well as within rural counties across different types of labor markets and by metropolitan adjacency. As of October 1, 2021, the cumulative COVID-19 mortality rate was 247.0 per 100,000 population in rural counties compared to 200.7 in urban counties. Higher COVID-19 mortality rates in rural counties are explained by lower average educational attainment and lower median household income. Within rural counties, mortality rates have been …

Race And Rhythm In Rock And Roll, Hector Qirko

Proceedings of the annual meeting of the Southern Anthropological Society

This chapter argues that contrary to conventional wisdom and the views of many scholars and critics, rock and roll’s most important rhythmic elements are derived from a complex blend of African, American, and European musical traditions. There is therefore no objective support for racialized characterizations of the “beat” that often serve, however unintentionally, to perpetuate stereotypes in discussions of both the genre and American popular music more broadly.

Pocahontas And Rebecca: Two Tales Of A Captive, Margaret Williamson Huber

Proceedings of the annual meeting of the Southern Anthropological Society

The Jamestown colonists’ accounts of their capture of Pocahontas, her reactions to life among them, and the consequences for the success of the colony differ radically from the Mattaponi Indian oral history of the same events, published in 2007. Both versions present themselves as “true” — that is, objective reporting of real events; but the fact that each inverts the other raises questions of validity and, ultimately, of historiography in general. This paper argues that the question of veracity is irrelevant to our interpretation of these accounts. Instead, we must take them as representations of a culturally conceived reality—that is, …
