The Relationship Between A Transient Scientific Phenomenon And Local Journalism At The Beginning Of The Gilded Age, Thomas Hockey

Faculty Publications

In the United States, the nineteenth century was the halcyon era for local newspapers. These publications were the primary source of public information at a time when other periodicals and books had low circulation. The purpose of this paper is to explore how local journalism in the nineteenth-century United States dealt with an occasion outside the boundaries of the commonplace: an unfamiliar natural phenomenon. My example is the total solar eclipse of 7 August 1869. Editors and journalists of the time largely were unaccustomed to covering celestial events. Nevertheless, they sensed—correctly—an interest in the solar eclipse. Articles about the approaching …

The Pagan Reception Of Judaism From The Sibylline Oracles: Insights From Pseudo-Seneca’S Octavia Regarding The Creation And Circulation Of Oral Sibylline Oracles By The Plebs, Kenneth Atkinson

Faculty Publications

According to tradition, the original collection of Sibylline Books ac­quired by the Roman monarch Tarquinius Priscus, which were kept in the Temple of Jupiter in the capital, were lost in the fire of 83 BCE. In 76 BCE, the Senate ordered the college of the quindecimviri to travel to the traditional centers of Sibylline activity in the East to find Sibylline Oracles to replace those destroyed in the fire. According to Lactantius, these officials collected many Oracles from private individuals. This reference suggests that Sibylline Oracles circulated widely. However, based on the witnesses regarding their consultation, it appears that the …

An Account Of The 1453 Ce Ottoman Siege Of Constantinople Interpreted Through A First Century Bce Jewish Text: How An Ancient Collection Of Second Temple Period Poems Changed The Course Of Western Civilization, Kenneth Atkinson

Faculty Publications

On 29 May 1453 CE, the besieged Christian occupants of Constantinople — the capital of the Byzantine Empire and the last surviving portion of the former Roman Empire — knew the end was near when they heard 50,000-80,000 angry Ottoman soldiers, including 5,000 to 10,000 of the elite Janissaries — the Sultan’s shook troops — preparing to breach its walls after a 53-day siege. The 7,000-man army defending the city knew that all was lost. The 21-year-old Sultan Mehmet II — given the sobriquet “the Conqueror” for capturing the city — leveled the roads so his army could reach Constantinople’s …

Appreciative Inquiry: Guiding Principles For Majority And Minority World Teams Conducting Research In Majority World Countries, Kendall Cotton Bronk, Lindsey C. Blom, Seren Fryatt, Flomo Mau Maiwo, Yabadel Appleton

Journal of Youth Development

The vast majority of youth development research takes place in minority world cultural contexts. To understand and nurture the optimal development of young people living in majority world countries, cross-cultural research teams are uniquely suited to conduct careful and culturally sensitive research in these settings. However, this is difficult. Navigating research in a new language, a different cultural context, and a far-away geographic location is challenging, and the risks of getting it wrong are high. We argue that the guiding principles of Appreciative Inquiry can help teams navigate many of the challenges inherent in conducting youth development research in majority …

Facilitate The Awesome:Creating Capacity For Teen Programs In Youth Development, Michael L. Wallace, Ashley M. Hall, Gary Frank Varrella, Pamela Watson, Kelly Anne Stewart, Brian Brandt

Journal of Youth Development

A critical need exists for adults who are properly prepared to meaningfully engage with adolescents. While utilizing teens in leadership and teaching roles has been gaining popularity and application, a developmental and skills-based approach for improving “trusted adult” capacity to engage with adolescents has not been comprehensively addressed in other programs or curricula. The “Facilitate the Awesome” short course focuses on advancing adult knowledge and skills related to supporting the physical, emotional, and social needs of adolescents. In an evaluation of 113 participants statistical significance was established for all the learning variables tested, using a sign test and estimated effect …

Examining The Activity-Related Correlates Of Latine Parent Support Of Adolescents In Organized Afterschool Activities, Fuko Kiyama, Sandra Simpkins

Journal of Youth Development

Objective: This study examined the relations between Latine parent perceptions of their seventh grade adolescents’ organized afterschool activity and their support of adolescents’ participation in these organized afterschool activities; and, whether these relations varied based on the organized afterschool activity’s ethnic cultural features.

Background: Although parent support bolsters adolescents’ success in multiple contexts, including organized afterschool activities, we know little about what promotes parent support. Method: Using data on Latine parent perceptions (N = 143) of their support (17 items), of organized afterschool activities (8 items) and ethnic cultural features (7 items), linear regression models were used to evaluate the …

Journal of Youth Development

The youth population bulge in Kenya comes with so many challenges such as poverty, gender inequalities, political inequities, the absence of adequate health and medical resources, low educational attainment, homelessness, increased involvement in violence, drugs, and alcohol, poor physical and mental health, a lack of key life skills, premature sexual involvement. Using inductive or “bottom up” thematic analysis, we explored experiences of the youth aged 18-34 (n=36), youth workers (n=26) and administrators of youth programs (n=22) on existing youth development programs and their alignment to the positive youth development principles. Six key findings from the study sufficed as follows: (1) …

The Association Between Sports Camp Participation And Perceivedcompetence And Independence Among Visually Impaired Youth, Mary A. Keene, Justin Haegele, Xihe Zhu

Journal of Youth Development

Research on sport camps for visually impaired youth is limited. The purposes of this study were to examine if visually impaired campers’ self-perception of their perceived competence and independence changed as a result of attending a one-week sports camp. Forty visually impaired campers ranging from 10-15 years of age, who attended a one-week sports camp, completed a survey study from two outcome measures of the American Camp Association Youth Outcomes Battery. A bivariate correlation analysis and descriptive analyses were conducted.

Do Horse Breed Association Youth Programs Promote Life Skills And Goaldevelopment For Youth With Attention Deficit Hyperactivity Disorder?, Julius Culwell, Makenna Foster, Molly Christine Nicodemus, Molly Friend, Holly Evans, Dean Jousan, Katherine Agbigail Holtcamp, Clay Cavinder, Toree Williams

Journal of Youth Development

Almost 10% of American youth are diagnosed with attention deficit hyperactivity disorder (ADHD). While not a learning disability, this diagnosis results in youth being labeled academically “at-risk.” While equine assisted services (EAS) promote an emotionally safe learning environment for at-risk youth, program availability is limited. Horse breed associations, however, offer programs nationwide for all youth, although these programs do not have a therapeutic intention. Therefore, the objectives of this study were to utilize a survey to determine program participation and associated development of life skills and goals for ADHD youth. A survey was developed with the following: 15 fixed-response multiple-choice …

Shall We Invent The Saints We Need? Pope Francis, The Politics Of Canonization, And Vincentian Saints, Matthieu Brejon De Lavergnée

Vincentian Studies

As the Church reforms and includes more laypeople in its power structure, a similar movement for inclusion should be made among the people who are considered for sainthood. In the past, most saints have been European men who led consecrated lives or who were martyred. This reflected the Church’s previous priorities, ideals, and demographics. But clericalism does not guarantee holiness, as recent sexual abuse revelations have shown, and martyrdom is an uncommon experience. Pope Francis and others have recognized that laypeople can lead extremely holy lives on both a small and large scale. Even the fulfillment of ordinary duties of …

Beyond Charity: The Development Of The Mission Of The Daughters Of Charity In Sub-Saharan Africa, Theresa Eke

Vincentian Studies

Theresa Eke recounts the history of the Daughters of Charity’s service in Africa and explains the evolution of their approach to poverty alleviation there. The Daughters learned the importance of knowing the cultures and languages of those they served. At first, they addressed poverty with donations of material goods, but later they empowered the poor, teaching them skills and helping them establish farms and businesses, particularly through helping them to purchase equipment. They learned to listen to what the poor themselves said would help them. They supported high school and university education, especially for women and girls. The Daughters also …

Conservative Management Of A Rare Clinical Phenomenon: Paraspinal Compartment Syndrome - A Review Of Existing Literature., Mark Lagreca, Arash Badragheh, Nathan Jones, Thomas Falconiero, Brian Danshaw

Orthopedic Surgery Resident Research

INTRODUCTION: This review of case series and case reports explores conservative management strategies for paraspinal compartment syndrome (PCS), a rare clinical condition. Extremity compartment syndrome has been shown to be managed most effectively with emergent surgical release of the fascial compartment. Given the rarity of PCS and the paucity of research in the literature, some authors have suggested the possibility of conservative treatment. There has been no study to date that has specifically investigated the cases of non-operative management of PCS.

MATERIALS AND METHODS: There are 16 case reports in the literature with 22 cases of PCS treated conservatively. The …

Striking A Balance: Market Shock & Responses In Automotive Components Manufacturing, Emma Lane Mcgahey

All Theses

This thesis examines the effects of extreme market shocks on supply chain dynamics within the automotive industry. Through an analysis of demand data from an automotive manufacturer to its component suppliers (January 2018 to May 2024), the study investigates the relationship between market shocks and supply chain responses, providing insights into how auto components inventory management handles downstream responses to market shocks. With supporting public data—from FRED, BLS, and the U.S. Census Bureau resources—we explore two primary relationships: the impact of market shocks on the Average Standard Deviation of Demand (SDO) and the effect of demand variability on expedited pricing …

Higher Order Bessel Beams Integrated In Time (Hobbit) With Engineered Light Frequencies And Applications In Computational Imaging, Tyler Cramer

All Theses

This thesis presents an adaptive optical system which leverages the frequency shifts from an acousto-optic deflector (AOD) form an array of uniformly spaced frequency diverse beamlets. These beamlets are then spatially transformed (wrapped) into a circular array forming a non-diffracting ring with an unprecedented orbital angular momentum (OAM) mode switching rate of 50Mhz with an OAM range of ±64. Along with frequency diversity, the non-diffracting range of the beams are analyzed 6 Rayleigh ranges of an equivalently sized gaussian beam. Inherent in the frequencies superposed on the AOD are associated relative phases which can be controlled to form sets of …

Real-Time Network Simulations For Ml/Dl Ddos Detection Using Docker, Luis D. Garcia

Master's Theses

As the integration of artificial intelligence (AI) within cybersecurity continues to

grow, machine learning (ML) and deep learning (DL) models are increasingly used to

detect cyber attacks. However, these models are rarely evaluated in real-time attack

scenarios to see how subtle changes from the real networking environment can affect

their predictions. To address this issue, we propose a scalable, platform-independent

Docker testbed specifically designed for simulating real-time Distributed Denial of

Service (DDoS) attack scenarios that allows researchers to deploy and evaluate their

pre-trained, ML and DL detection models. Our framework is simple to configure

and can run across Intel and …

Performance Of Multi-Composite Materials With Corrugated And Cell Geometries Under Low-Velocity Impact, Lukas S. Kolbl

Master's Theses

Composite structures have demonstrated great potential to improve mechanical performance in various applications, including ballistics protection. This study demonstrates that the integration of geometrically optimized composites into core-face sheet assemblies provide great impact resistance. The research investigated the performance of two composite manufacturing methods under low-velocity impact through residual strength and damage comparisons. Corrugated core composites were produced with traditional manufacturing methods, namely compression molding, using twelve stacking sequences. These stacking sequences were chosen to represent four laminate groups, where a unique fiber orientation scheme was employed across three laminate thicknesses (6, 8, and 12 layers). In contrast, honeycomb and …

Finite Element Analysis And Verification Of Transverse Mechanical Properties Of Generally Cylindrical Orthotropic Constitutive Modeling Of 3-Phase Nanocomposite Unit Cell, Christopher J. Hawkins

Master's Theses

Fiber-reinforced composites are increasingly popular due to their specific strength and stiffness, making them ideal for high-performance applications. However, these materials primarily exhibit superior properties in-plane, while their out-of-plane characteristics remain comparatively weaker. Previous research has shown that the most effective method to enhance out-of-plane properties involves the incorporation of carbon nanotubes. Experimental tests have demonstrated significant improvements in properties such as tension, flexural, short beam shear, and fracture toughness. Alongside these experimental studies, analytical equations have been developed to predict the behavior of these composites under various loading conditions, including tension, bending, shear, and fracture. Existing models primarily address …

Bonsai Merkle Tree Streams: Bulk Memory Verification Unit For Trusted Program Verification System, Richard J. Rios

Master's Theses

Today, all modern computing systems are undoubtedly vulnerable to numerous types of attacks that could be targeted toward any layer of the system from dedicated hardware to highly abstracted software. Unfortunately, many devices and systems naturally contain inadequately protected components or software modules that un- dermine their security as a whole. Additionally, security is heavily variable system to system, and has a huge dependence on adequate implementation and ongoing support from device and software manufacturers. To address these various security issues in a very general way, TrustGuard, a containment security system utilizing an external device called the Sentry that would …

An Investigation Into The Use Of Amateur Astronomy Equipment For Optical Orbit Determination Using A Mobile Telescope Platform, Johan C. Govaars

Master's Theses

The process of optical orbit determination has long been in the domain of large organizations and stationary observatories with highly specialized scientific equipment. This thesis seeks to determine not only if satellites can be captured regularly using purely commercial-off-the-shelf (COTS) equipment, but also if initial orbit determinations can be made using that data. Moreover, the use of a mobile telescope platform allows users to circumvent the restrictions of fixed observatories such as low horizon viewing restrictions or existing light pollution.

A completely COTS setup was utilized that included an 8-inch Celestron NextStar 8SE telescope with an f/6.3 focal reducer and …
