Magnetic Massive Stars As Progenitors Of ‘Heavy’ Stellar-Mass Black Holes, V. Petit, Z. Keszthelyi, R. Macinnis, D. H. Cohen, R. H. D. Townsend, G. A. Wade, S. L. Thomas, S. P. Owocki, J. Puls, A. Ud-Doula

Aerospace, Physics, and Space Science Faculty Publications

The groundbreaking detection of gravitational waves produced by the inspiralling and coales- cence of the black hole (BH) binary GW150914 confirms the existence of ‘heavy’ stellar-mass BHs with masses >25 M . Initial characterization of the system by Abbott et al. supposes that the formation of BHs with such large masses from the evolution of single massive stars is only feasible if the wind mass-loss rates of the progenitors were greatly reduced relative to the mass-loss rates of massive stars in the Galaxy, concluding that heavy BHs must form in low-metallicity (Z ,:S 0.25 0.5 Z ) environments. However, strong …

Tunneling Nanotubes: An Alternate Route For Propagation Of The Bystander Effect Following Oncolytic Viral Infection, Justin Ady, Venugopal Thayanithy, Kelly Mojica, Phillip Wong, Joshua Carson, Prassanna Rao, Yuman Fong, Emil Lou

Biomedical Engineering and Sciences Faculty Publications

Tunneling nanotubes (TNTs) are ultrafine, filamentous actin-based cytoplasmic extensions which form spontaneously to connect cells at short and long-range distances. We have previously described long-range intercellular communication via TNTs connecting mesothelioma cells in vitro and demonstrated TNTs in intact tumors from patients with mesothelioma. Here, we investigate the ability of TNTs to mediate a viral thymidine kinase based bystander effect after oncolytic viral infection and administration of the nucleoside analog ganciclovir. Using confocal microscopy we assessed the ability of TNTs to propagate enhanced green fluorescent protein (eGFP), which is encoded by the herpes simplex virus NV1066, from infected to uninfected …

Backpacking Brothers: An Experiential, Adventure Education Program To Transform Rape Culture And Prevent Sexual Violence, Matthew Lynn

Capstone Collection

Sexual violence is a public health crisis in the United States and globally, that has devastating interpersonal, social, psychological, spiritual and economic impacts. The root causes of sexual violence are tied to all forms of oppression. The normalization and perpetuation of sexual violence is buttressed by cultural paradigms used by media, religion, education and other systems that maintain rigid gender roles and power dynamics. There are promising initiatives for preventing sexual violence before it occurs. This paper explores one of those initiatives called Backpacking Brothers. The purpose of Backpacking Brothers is to engage middle school boys in an adventure education …

The 2015 Al-Shabaab's Attack In Garissa, Kenya. An Immersion Into The Structural, Socio-Political And Psychological Roots Of Violence, Mathilde Simon

Capstone Collection

The paper studies the attack conducted by the Somali insurgent group al-Shabaab in Garissa, north of Kenya, on April 2, 2015. In contrast to judgmental and narrow- minded media explanations which tended to dominate the debate after the attack, the present paper uses conflict theories in order to investigate the deep roots of violence. It questions how a group such as al-Shabaab has been able to emerge, to find support and to become a major actor in the Horn of Africa, and to some extent internationally. It draws on Basic Human Needs, Collective Psychology and Structural and Cultural Violence theories …

Scalable Production And Applications Of Metal Oxide Nanowires., Tu Quang Nguyen

Electronic Theses and Dissertations

Metal oxide nanowires are materials of interest in number of applications such as lithium ion batteries, solar cells, catalyst support, and gas sensing due to their unique charge transport properties and short diffusion length scales. To incorporate nanowires for any applications, one would need hundreds of grams to kilograms of these nanowires. However, state-of-the-art methods for producing metal oxide nanowires are limited to producing only milligrams to a gram in a batch. Hence, there is a need to develop scalable and cost effective processes and reactors to address this challenge. Direct gas phase oxidation of zinc metal powders using a …

The Role And Regulation Of Inhibitor Of Kappa B Kinase In The Impaired Monocyte Response., Norman James Galbraith

Electronic Theses and Dissertations

Trauma, major surgery and systemic infection can lead to a subsequent immunosuppressed state which can predispose patients to nosocomial infection and death. Approximately a sixth of patients will have impaired monocyte function, as determined by decreased HLA-DR expression or decreased TNF-α production in response to ex-vivo lipopolysaccharide (LPS) stimulation. This project aimed to develop an in-vitro model of impaired monocyte function using isolated monocytes from healthy volunteers, to study the effect of monocyte impairment on IκK signaling, and determine the role of IκK in the impaired monocyte response. These studies have provided the following results:

Eastern Flames In The Mind On Fire: A Study Of Eastern And Qur’Anic Influences On Ralph Waldo Emerson, Mohammed Qays Khaleel Alqaisi

Graduate Theses/Dissertations

Ralph Waldo Emerson's interest in the east is evident throughout his essays, poems and lectures. He shows his fascination with the eastern cultures, religions and poetry when he quotes from eastern texts to strengthen his ideas, such as the notion of the Over-Soul, illumination, knowledge and nature. He regards the east as an ignored territory of knowledge that contains invaluable wisdom waiting to be explored by western thinkers. As the world witnesses an increasing gap between the east and the west, Emerson represents the universal way of thinking, as he believes in seeking knowledge in every part of the world …

Community Construction In The Basic Writing Classroom, Jennifer Nicole Collins

Graduate Theses/Dissertations

This study analyzed students' perceptions of community construction within the English 100 classroom and university at large as well as analyzed the instructor's role as a "tutor" and the impact this has on students' perceptions of community within the classroom. Composition theorist Kenneth Bruffee proposes that one solution for creating community for basic writers, those students least prepared for the college composition classroom, is peer tutoring. The traditional classroom has not worked for basic writers because it lacks a sense of community. The goal is to change the social context for learning and make it less hierarchical. Given the nature …

Identifying The Key Components Of Place-Conscious Pedagogy To Help Maximize Rural Potential, Amber Marie Dlugosh

Graduate Theses/Dissertations

By using reflective and observational data from a rural high school English classroom's endeavor to launch a community-wide online literary magazine, this study uncovers the key components of place-conscious curriculum and instruction that must be present for benefits to transpire. Focusing on a rural, predominantly-caucasian school district, the study tracks 64 students who were enrolled in four sections of a senior-level writing course. Previous research asserts that place-conscious curriculum choices that involve student contributions to the community prove to have significant potential for rural schools. The investigator observed a significant decrease in student apathy, academic gains within the content area, …

Using Behavior Skills Training To Teach Effective Conversation Skills To Individuals With Disabilities, Allison L. Schmidt

A behavioral skills training (BST) package consisting of instructions, modeling an appropriate conversation, participant rehearsal, and constructive feedback, was used to teach appropriate conversation skills to three adults with developmental disabilities. A task analysis was used to define the steps of having a conversation. These steps included greetings, initiations, initiating a topic, responding, and maintaining a topic as the target skills. A nonconcurrent multiple baseline design across participants was used; an A-B-C format was embedded within the design for participants 1 and 2. Participant 3 was assessed using an A-B format. In situ was measured across three settings: each participant's …

Concurrent Biological, Electromagnetic Pulse, And Cyber Attacks - A Challenge To The Interagency Response, Patricia Rohrbeck

Graduate Theses/Dissertations

The U.S. including its military depends on an electrical grid and electricity-based critical infrastructure. An electromagnetic pulse (EMP) and cyber attack can disable not just a significant portion of the electrical grid and critical infrastructure, but also the networkcentric military response to such an attack. There is a large range of actors that might attempt EMP attacks against the U.S.. Health surveillance systems are network-centric, and if mass destruction is the goal of an adversary, launching a biological attack concurrently with EMP and cyber attacks may achieve this goal. Current agency response plans focus on one WMD attack at a …

“Frames” And Bias: How A Lack Of Context In Middle East News Coverage Can Impact U.S. Foreign Policy, Jennifer Lois Moore

Graduate Theses/Dissertations

This thesis is a critical examination into how American mainstream news media outlets often neglect to incorporate religious, cultural and historical context into their coverage of the Middle East. I show through my research and analysis that the news coverage of the Middle East, even at the highest echelons of American journalism, is often lacking in sophistication in terms of cultural and religious context, sometimes to the point of affecting its fairness and accuracy. The danger of this is that it has the power to grossly simplify and reduce to an “us versus them” frame an entire contingent of the …

Essay: Extending Comparative Fault To Apparent And Implied Consent Cases, Aaron D. Twerski, Nina Farber

Brooklyn Law Review

This article challenges the traditional view of consent as a binary issue. Because “lack of consent” is an element of an intentional tort, courts do not apply comparative responsibility principles and therefore must find that plaintiff has either consented to the invasion of her person or not. In cases where consent is predicated on apparent consent or implied consent, however, the all–or-nothing approach to consent fails to take into account that both plaintiff and defendant may have been responsible for a miscommunication as to consent. This essay focuses on well-known cases and situations where both parties likely contributed to a …

Parasocial Relationships With Transgender Characters And Attitudes Toward Transgender Individuals, Lizhen Zhao

Dissertations - ALL

The transgender population lives in a condition of serious discrimination, poverty and violence (NCTE, 2014). Few studies, however, have been conducted to understand people’s attitudes toward this population and factors that affect the responses. Applying the Parasocial Contact Hypothesis (Schiappa, Gregg & Hewes, 2005), this thesis investigated the relationship between audiences’ positive and negative parasocial relationships with transgender characters in TV and their attitudes toward transgender people in real life. A survey method was employed to address research questions and test hypothesis. Results show a significant association between parasocial relationship (positive or negative) and attitudes toward trans people in real …

Reacting To Negative Self-Relevant Information In An Interpersonal Context, Mingxuan Tan

Dissertations - ALL

Using a newly developed perspective provided by cross-cultural research, the concept of face, I conducted three experiments to examine the impact self-construal, feedback source and interpersonal contexts have on one’s reactions to negative self-relevant information. In these experiments, characteristics of contexts including audience’s status, audience’s standard, audience’s performance and publicness of the situation were manipulated to examine participants’ reactions to feedback pertaining to an ostensibly important ability. These experiments revealed that compared to the interdependent self-construal, the independent self-construal was associated with higher levels of self-serving responses. These self-serving responses include attributing failure to external factors and attributing success to …

Aftermarket Supermarket | A Speculative Retrospective, Alexander Kim

Architecture Senior Theses

In the preface to Delusive Spaces: Essays on Culture, Media and Technology, media theorist Eric Kluitenberg writes that “the delusion of the new”1 pollutes our theorizations of new media. This sort of technocratic fetishization of emergent technologies can only amount to a surfatial investigation of its effects or capabilities. Architectural investigations of virtual reality and other new media systems suffer from this tendency as well. Content-based experimentation and criticism obsess over the simultaneously exciting and daunting prospects of what we can now do or make with recent digital developments. There’s definite value in such endeavors, but frankly, in the grand …

A Legal And Ethical Puzzle: Defense Counsel As Quasi Witness, Elizabeth Slater

Fordham Law Review

The U.S. criminal justice system is built on the concept of an adversarial trial. The defense and prosecution present competing narratives to a neutral audience that judges whether the prosecution has proved its case beyond a reasonable doubt. In this context, defense counsel is expected to be a zealous advocate for the defendant, providing the most effective representation possible in light of the evidence presented by the government. However, there are occasions outside of trial where defense counsel’s traditional role changes and she is asked to disclose, not to the jury, but to the court, personal opinions and knowledge about …

The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Wilkerson

Department of Animal Science: Dissertations, Theses, and Student Research

Distillers grains (DG) contribute to cattle sarcoplasmic reticulum (SR) membrane instability by increasing poly-unsaturated fatty acid (PUFA) content in the SR membrane, possibly resulting in early postmortem calcium (Ca) leakage and improved tenderness. Mitochondria are relatively easy to isolate intact and provide the opportunity to study Ca in an SR model. The objective of this research was to determine the influence of diet and oxidation on Ca release from mitochondria. Cattle (n = 48) were fed a corn-based finishing diet with or without deoiled, dried DG (50% DM basis). Steaks from each strip loin were aged for 2, 8, …

Heteroglossic Practices In A Multilingual Science Classroom, Lydiah Kananu Kiramba

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This paper uses sociocultural theories of language learning to investigate how teachers and students navigate between monolingual institutional policies and the multilingual realities encountered in a rural Kenyan fourth-grade classroom. The paper addresses not only how learners’ communicative repertoires are deployed to make meaning in a foreign language instruction context but also the sociocultural significance of these communicative practices. Results illustrate how the science teacher used heteroglossic practices to mediate students’ access to literacy, hence, supporting the content learning and language development of students. Both the science teacher and the students preferred a more flexible use of language to make …

Interventions To Increase Vaccination Rates In Homeless Adults Aged 50 Years And Older In A Shelter-Based Clinic, Rubeena Smith

Doctor of Nursing Practice

Pronounced disparities in adult immunizations exist across the country. In homeless adults over 50 years of age with chronic diseases, coverage rates for influenza and pneumococcal vaccinations falls at 30% as compared to the 60% coverage rate found in the general public. Hepatitis B immunization rates are also significantly lower in the elderly homeless population. Increased prevalence of chronic diseases in the elderly homeless shelter residents’ increase their risk for severe complications following influenza, hepatitis B and meningococcal infections. To prevent disease epidemics and further disability in the homeless population, the need for appropriate and timely vaccinations is critical. Attitudes …
