Increasing rates of human papillomavirus (HPV)-driven oropharyngeal cancer (OPC) have largely offset declines in tobacco-associated head and neck squamous cell carcinoma (HNSCC) at non-OPC sites. Host immunity is an important modulator of HPV infection, persistence, and clearance, and also of immune evasion in both virally- and nonvirally-driven cancers. However, the association between collective known cancer-related immune gene variants and HNSCC susceptibility has not been fully characterized. Here, we conducted a genetic association study in the multiethnic Veterans Affairs Million Veteran Program cohort, evaluating 16,050 variants in 1,576 immune genes in 4,012 HNSCC cases (OPC = 1,823; non-OPC = 2,189) and …
Log-Optimal (D + 2)-Configurations In D–Dimensions, Peter D. Dragnev, Oleg R. Musin
Log-Optimal (D + 2)-Configurations In D–Dimensions, Peter D. Dragnev, Oleg R. Musin
School of Mathematical & Statistical Sciences Faculty Publications
We enumerate and classify all stationary logarithmic configurations of d + 2 points on the unit sphere in d–dimensions. In particular, we show that the logarithmic energy attains its local minima at configurations that consist of two orthogonal to each other regular simplexes of cardinality m and n. The global minimum occurs when m = n if d is even and m = n + 1 otherwise. This characterizes a new class of configurations that minimize the logarithmic energy on Sd−1 for all d. The other two classes known in the literature, the regular simplex (d + 1 points on …

School of Earth, Environmental, & Marine Sciences Faculty Publications
House geckos share living quarters with humans in the tropical and subtropical regions inhabited by these reptiles. Gecko behavior, biological traits, continuous exposure to suspended particulate matter 0 µm in diameter (PM10) and dust, as well as status as exotic species, motivated the choice of these species to examine environmental exposure to ambient air pollutants, in particular metals, and subsequent accumulation in these organisms. One part of the study was conducted in Tamaulipas (Mexico) where Hemydactylus frenatus is abundant in urban and industrial environments, the other part was conducted in Andalucia (Spain) where Tarentola mauritanica is found in similar environments. …
Cognitive Appraisal, Workplace Social Courage, And Psycap, Quinn Denny
Cognitive Appraisal, Workplace Social Courage, And Psycap, Quinn Denny
Doctoral Dissertations and Projects
This study responds to calls for empirical investigation of courage as well as the discovery of positive psychological capital (PsyCap) antecedents. Courage and PsyCap are considered positive constructs associated with beneficial workplace outcomes. As an example, Workplace Social Courage (WSC) predicts organizational citizenship behavior (OCB). PsyCap is robustly correlated with performance outcomes, well-being, and sustainability. For its societal appeal, courage is not yet robustly validated. Further, interventions have demonstrated resultant increases in PsyCap, yet little is known of its antecedent variables. Also, to be discovered, are what variables mediate WSC. These gaps in research present opportunity for additional empirical investigation …

Financial Capability – Examining The Impact Of Financial Education On U.S. Military Members, Philip Mason Chapman
Financial Capability – Examining The Impact Of Financial Education On U.S. Military Members, Philip Mason Chapman
Doctoral Dissertations and Projects
In 2018 a national survey was conducted of 27,091 participants designed to gauge financial capability. While the survey revealed that financial education matters, there is a gap between those with a military background and their civilian counterparts. This dissertation is designed to address how this discrepancy can exist when military individuals have unlimited access to financial education. Even with this access, investors with a military background make poorer financial decisions while simultaneously claiming to have a higher level of financial satisfaction and financial knowledge. Financial education has long been associated with an individual’s desire to seek professional financial assistance and …
Shame, Stigma, And Callousness: A Moderated Mediation Study Of Sex Offender Empathy Strength, Robert M. Ferow
Shame, Stigma, And Callousness: A Moderated Mediation Study Of Sex Offender Empathy Strength, Robert M. Ferow
Doctoral Dissertations and Projects
Callous, lacking sympathy, heartless, and cold are but a few synonyms for people that demonstrate a deficit in empathy. Psychologists, criminologists, and sociologists have tried to explain this phenomenon of callousness, or lack of empathy found in criminals for hundreds of years. Issues of definitions of empathy, personality disorders, character flaws, and even neurobiological issues have been studied in their relation to empathy. Theories of criminology have been presented to explain the reasons for lack of empathy. However, as of yet, no conclusive findings demonstrate the order or function in loss of empathy strength. This study will endeavor to describe …

Philosophical Psychopathology And Individuation: The Archetype Of The Self And Rediscovering Personality, Alyc Jordan-Crump Rideout
Doctoral Dissertations and Projects
Psychopathology has been associated to personality in trait characteristics as a contributing factor to mental illness, but the degree to which personality development as an influence in mental pathologies remains under researched at a phenomenological level. Thus, leaving a significant gap in psychopathological clinical literature on the functional role personality development is associated with psychopathology. In the modern era, the medical symptomology model of mental illness set by the DSM serves as the justification for psychotropic medication prescription as well as the diagnostic criteria for mental pathology but, there is limitations to functional ideals of mental health based off diagnostic …

Attracting And Sustaining Volunteers: Leadership Impact On The Recruitment And Retention Of Volunteers In Nonprofit Organizations, And Differences Observed When Organizations Are Predicated On Faith, Lascel A. Webley Jr.
Doctoral Dissertations and Projects
The term “volunteer” has been formally acknowledged for more than 200 years (Dreyfus, 2018; Haski-Leventhal et al., 2018). It is synonymous with one who freely offers to participate in a task that benefits others. During the modern era, these tasks have included, but have not been limited to, establishing communal programs, presenting technical assistance, conducting conferences, fundraising, and supporting identified causes or groups (Alfes et al., 2017). In most instances, the tasks are rendered through nonprofit organizations. Therefore, volunteers represent invaluable assets as they are economic resources who contribute to accomplishing stated organizational goals (Tonurist & Surva, 2017). While more …
At Any And All Hazards: Manifest Destiny, The Monroe Doctrine, And The Balance Of Power In North America, Keith Thomas Ressa
At Any And All Hazards: Manifest Destiny, The Monroe Doctrine, And The Balance Of Power In North America, Keith Thomas Ressa
Doctoral Dissertations and Projects
Contrary to the beliefs of New Left historians seeking to revive the once discredited theory that American territorial expansion was driven by a motivation to expand the institution of slavery, a position that I have dubbed the Neo-Abolitionist view, rather that Manifest Destiny developed as an early national security strategy and primitive strategic doctrine, what might be termed in today’s vernacular as a kind of preemptive threat displacement theory. That is, early on in the history of the Republic, many American statesmen believed that the most effective means of preventing a “balance of power” geopolitical system from being established in …

Police Demographics And Stress Relief Program Utilization, Michael Wayne Whittington
Police Demographics And Stress Relief Program Utilization, Michael Wayne Whittington
Doctoral Dissertations and Projects
Police officers face challenges from operational and organizational stressors. Officers often have access to stress relief programs offered by their employers such as Peer Support Programs, Employee Assistance Programs, or Chaplaincy Programs. The implementation of these stress relief programs is based on the perception of need and anecdotal evidence. Police stress and stress relief studies offer mixed results as to the way an officer chooses one program or another. One understudied area to determine stress relief program utilization is demographics. Variables such as experience, education, marital status, race, sexuality, and gender may factor into the decision as to which stress …

French Military Tactics In The American Civil War: An Analysis Of The Influence Of Antoine Henri Jomini’S Principles In Two Selected Battles And A Campaign, Michele M. Hawes
French Military Tactics In The American Civil War: An Analysis Of The Influence Of Antoine Henri Jomini’S Principles In Two Selected Battles And A Campaign, Michele M. Hawes
Doctoral Dissertations and Projects
Between 1796 and 1815 the Napoleonic Wars had Europe in a constant state of conflict. Ultimately, a shifting coalition of Europeans defeated the French Emperor, but not before the world was changed forever. The Napoleonic Wars planted the seeds of the unified states of Germany and Italy, the United States doubled in size with the Louisiana Purchase, and perhaps most significantly, the definition of modern warfare became aligned with French military tactics. On the heels of the French Revolution, Napoleon had come remarkably close to conquering Europe through the combination of his leadership, audacity, and mastery of the art of …

Civil Gang Injunction Effects: The Perceptions Of Residents And Neighbors Of Their Safety, Marc M. Collazo
Doctoral Dissertations and Projects
This hermeneutic phenomenological study aimed to assess the general effectiveness of civil gang injunctions based on community members' perceptions of their safety in Los Angeles County, California. The theory that served as the foundation for this study was social disorganization, as interpreted by Shaw and McKay (1972). It helped to gauge how well community members understood their lived experiences and perceived the effects of injunctions on their safety. The following question guided this study: Do local citizens believe communities are safer and more secure when civil gang injunctions are used? Eight community members from two Los County cities were chosen …
A Multidimensional Grounded Theory Study Of Personal Confidence Among Female Theological Educators, Claudia Dempsey
A Multidimensional Grounded Theory Study Of Personal Confidence Among Female Theological Educators, Claudia Dempsey

The purpose of this qualitative grounded theory study was, therefore, to explore common antecedents and deterrents of confidence so as to provide a theoretical framework related to the phenomenon of underconfidence among female theological educators while also providing insight into the multidimensional nature of confidence. The selected audience of this study were Christian female educators teaching within theological schools accredited by the Association of Theological Schools (ATS). …
John's Canonical Portrait Of Christ: A Biblical-Theological Approach To The Depiction Of The Glorified Christ In Revelation 1, Christopher Matthew Carpenter
John's Canonical Portrait Of Christ: A Biblical-Theological Approach To The Depiction Of The Glorified Christ In Revelation 1, Christopher Matthew Carpenter
Doctoral Dissertations and Projects
Throughout the history of evangelical scholarship, a significant lacuna has formed in Apocalyptic studies. Many theologians have expressed fear or uncertainty concerning the text of Revelation as numerous ambiguous aspects exist within the Apocalypse. A proposed path forward into the gap in scholarship is to return the focus to the intent of the author of Revelation, John the apostle, and examine the definitive truths of the text. John’s priority is revealed in the initial chapter as he depicts the subject of his Apocalypse, Jesus Christ. This intent is revealed in John’s use of allusions, metaphors, and other rhetorical devices through …
The 2015 Migrant Crisis: An Impact To Germany?, Irish Nicole Solinsky
The 2015 Migrant Crisis: An Impact To Germany?, Irish Nicole Solinsky
Doctoral Dissertations and Projects
The 2015 European Migrant Crisis emerged when an influx of refugees settled in Europe from 2015-2019. The asylum seekers fled their homelands to evade a myriad of crises such as violence and war, corruption and abuse, and poor socioeconomic conditions. Of the European states, Germany welcomed the largest number of migrants. This was in part due to Germany’s existing immigration policies in a post-Second World War environment, but also due to Germany’s resounding economic strength. Germany has significantly low unemployment rates and the highest gross domestic product (GDP) in Europe. As such, Germany’s position is one of uncontested significance within …

Effect Of Intense Social Media Use On Middle School At-Risk Students Test Scores In Science And Math: An Ordinal Logistic Regression Analysis, Terry M. Johnson
Effect Of Intense Social Media Use On Middle School At-Risk Students Test Scores In Science And Math: An Ordinal Logistic Regression Analysis, Terry M. Johnson
Doctoral Dissertations and Projects
The purpose of this quantitative correlational study was to investigate the intensity of social networking use, gender, and socioeconomic status as possible predictors of eighth grade at-risk middle school students’ math and science test scores. Because this study hypothesized a general linear model between an ordinal response variable and more than one explanatory variables, ordinal logistic regression analysis was used. Social media is pervasive in the daily lives of students and so it can have a possible deleterious influence on student achievement. This idea continues to animate practitioners, researchers, parents, and all others interested in the achievement and success of …
Highly Pathogenic Avian Influenza, Andrew N. Rowan, Kathleen Rowan
Highly Pathogenic Avian Influenza, Andrew N. Rowan, Kathleen Rowan
WellBeing News
The avian flu virus was the agent that caused the devastating worldwide influenza pandemic in 2018 that killed an estimated 50-100 million people, and health authorities continue to pay close attention to periodic outbreaks of avian flu. Currently, an H5N1 influenza virus is leading to millions of wild birds and domestic poultry deaths. Recently, this virus spread in a mink farm in Spain, raising the stakes that it might be able to spread among humans. While the current avian flu pandemic is a major economic problem for global farms and a major animal welfare concern for domestic poultry and wild …
Rhino Conservation In Africa, Andrew N. Rowan
Rhino Conservation In Africa, Andrew N. Rowan
WellBeing News
The recovery of white rhinos from a small population of 20 animals in 1895 to tens of thousands today is a major conservation success story, but we are again facing a rapid decline in the numbers of both species of African rhinoceros due mainly to poaching. Demand for rhino horn, mainly from the Far East, has led to an epidemic of poaching. The healthy population of white rhinos in South Africa’s Kruger National Park has fallen from just under 12,000 individuals in 2010 to around 2,200 in 2022. At the current rate of decline, white rhinos will be eliminated from …
Update – Food & Drug Administration’S Animal Testing Mandate, Andrew N. Rowan
Update – Food & Drug Administration’S Animal Testing Mandate, Andrew N. Rowan
WellBeing News
Following the end of the Second World War, the World Medical Association developed new ethical guidelines regarding research involving human subjects. These guidelines included requirements to obtain informed consent from research subjects but also emphasized the importance of conducting animal research before engaging in human clinical trials and other human research. This principle was included in legislation mandating the FDA to require prior animal research before permitting human trials of new drugs. That mandate was recently eliminated by new US legislation cosponsored by Senators Cory Booker and Rand Paul. The FDA can now encourage non-animal methods and no longer has …
The Effect Of Interactive Computerized Simulation On Approach To Learning In Undergraduate Nursing Students, Claudia Mitchell
The Effect Of Interactive Computerized Simulation On Approach To Learning In Undergraduate Nursing Students, Claudia Mitchell
Dissertations
Competency standards require baccalaureate nursing graduates to demonstrate knowledge, understanding, and the ability to solve complex problems. In an effort to achieve these program outcomes, educators seek empirical evidence related to the learning process and the effect of innovative teaching strategies, such as simulation, on the learner. Traditional teacher-centered educational models which foster rote learning may not promote a deep approach to learning and facilitate student understanding. Students who utilize deep learning strategies seek meaning and understanding and often have higher quality learning outcomes. The purpose of this quasi-experimental study was to examine the effect of interactive computer-based clinical simulation …

Food packaging is an important concept for consumer satisfaction and the increased shelf life of food products. The introduction of novel food packaging materials has become an emerging trend in recent years, which could be mainly due to environmental pollution caused by plastic packaging and to reduce food waste. Recently, numerous studies have been carried out on nanoclays or nanolayered silicate to be used in packaging material development as reinforcing filler composites. Different types of nanoclays have been used as food packaging materials, while montmorillonite (MMT), halloysite, bentonite (BT), Cloisite, and organically modified nanoclays have become of great interest. The …
