Experimental Validation Of A Numerical Forward Model For Tunnel Detection Using Cross-Borehole Radar, Arvin Farid, Jose A. Martinez-Lorenzo, Akram N. Alshawabkeh, Carey M. Rappaport

Civil Engineering Faculty Publications and Presentations

The goal of this research is to develop an experimentally validated twodimensional (2D) finite difference frequency domain (FDFD) numerical forward model to study the potential of radar-based tunnel detection. Tunnel detection has become a subject of interest to the nation due to the use of tunnels by illegal immigrants, smugglers, prisoners, assailants, and terrorists. These concerns call for research to nondestructively detect, localize, and monitor tunnels. Nondestructive detection requires robust image reconstruction and inverse models, which in turn need robust forward models. Cross-Well Radar (CWR) modality is used for experimentation to avoid soil-air interface roughness. CWR is not a versatile …

Do Shareholders Penalize Bank Boards And Management For The Financial Crisis?

Fordham Business Student Research Journal

The 2007-2008 financial crisis was a pervasive shock that profoundly impacted the financial services industry. Often described as the worst economic crisis since the Great Depression, this event provides a unique opportunity to examine the consequences experienced by members of boards of directors and top management at bank holding companies for what shareholders may perceive as failures in oversight and excessive risk-taking. This study examines whether shareholders penalized top management at banks and provides some new evidence of the crisis’s impact on management careers. Using the 36 largest American bank holding corporations by assets as a sample, we examine director …

Can You Hear Us Now? Investigating The Effects Of A Wireless Grid Social Radio Station On Collaboration And Communication In Fragile Populations, Sarah Anna Chauncey

School of Information Studies - Dissertations

The ability to interact with peers and coworkers in online digital networks is essential in learning and business environments. Our digital participatory culture is based on communication in response to purposeful activity and is facilitated by information and communication technologies (ICT). Students with emotional, behavioral, and learning disabilities are often disengaged and excluded from this knowledge-building conversation. This disengagement results in a cycle of failure exhibited through diminished self-efficacy and inadequate academic and emotional self-regulation. A critical goal of those who work with these students is to bolster their resilience, persistence, participatory, and communicative skills--to invite them back into the …

A Truly Radical Idea In Social Studies Education: Teach The State Standards, Richard Gardiner

Journal of Contemporary Research in Education

State social studies standards are reflective of the concepts of Bloom’s taxonomy, emphasizing the development of higher order thinking skills. Standardized social studies tests, on the other hand, are not reflective of Bloom’s taxonomy and almost exclusively test for memorization and identification. In other words, the standards target very different objectives than the standardized tests are designed to assess. If, then, the central objective is to achieve adequate or higher standardized test scores, we must admit that it is not “standards-based” education that is desired, but rather test-focused instruction.

Global Journeys: From Transnationalism To Diaspora, Nadja C. Johnson

Journal of International and Global Studies

The emerging interest in diasporic studies has recently begun to permeate various academic disciplines, none more so than cultural studies. Today, there are numerous articles, books, and journals that have begun to engage in heated discussions on the importance of recognizing and understanding diaspora communities as collective transnational organizations and movements. However, sociology, the discipline out of which traditional migration theory emerged, has seemingly been more reluctant to embrace the concept of diaspora. In this article, I initiate a much needed conversation between traditional sociological migration theory and theories of diaspora emerging out of cultural studies. I look at the …

Marine Fungi Of U.S. Gulf Of Mexico Barrier Island Beaches: Biodiversity And Sampling Strategy, Allison Kathleen Walker

Dissertations

Marine fungi are an important but often overlooked component of marine ecosystems. Primarily saprotrophic, they are vital to coastal nutrient cycling processes and food webs. However, basic marine fungal distribution data are lacking in many parts of the world, as is knowledge of the sampling intensity required to characterize the biodiversity of these communities. The roles of substrate, season and latitude in shaping intertidal ascomycete community structure were examined for the U.S. Gulf of Mexico, and the role of sampling frequency on species richness estimates was also addressed. Best sampling practices were developed and 750 collections of beach detritus, sand …

Mechanism Of Action And Gold Nanoparticle Delivery Of Pt(Iv) Prodrugs Of Cisplatin, Yi Shi

Chemistry - Dissertations

The antitumor effects of platinum(IV) complexes, considered prodrugs for cisplatin, are believed to be due to biological reduction of Pt(IV) to Pt(II), with the reduction products binding to DNA and other cellular targets. In this work we used pBR322 DNA to capture the products of reduction of oxoplatin, c,t,c-[PtCl₂(OH)₂(NH₃)₂], 2, and a carboxylate-modified analog, c,t,c-[PtCl₂(OH)(O₂CCH₂CH₂CO₂H)(NH₃)₂], 3, by ascorbic acid (AsA) or glutathione (GSH). Since carbonate plays a significant role in the speciation of platinum …

Molecular Mechanisms Regulating Neonatal Oocyte Survival And Primordial Follicle Formation In The Mouse Ovary, Robin L. Jones

Biology - Dissertations

In mammals, formation of the primordial follicle is a complex process involving the breakdown of germ cell cysts, where oocytes must separate from each other and subsequently become surrounded by somatic cells. As cysts separate, a large number of germ cells are lost by apoptosis, however the mechanisms by which cyst breakdown and germ cell death occur are not well understood. We first hypothesized that two anti-apoptotic regulators from the BCL2 family of proteins, BCL2 and MCL1, may be responsible for regulating neonatal oocyte survival. To elucidate the effects of BCL2 in the neonatal ovary, we examined ovaries of both …

Voltage Effects On Cells Cultured On Metallic Biomedical Implants, Seyed Morteza Haerihosseini

Biomedical and Chemical Engineering - Dissertations

Electrochemical voltage shifts in metallic biomedical implants occur in-vivo due to a number of processes including mechanically assisted corrosion. Surface potential of biomedical implants and excursions from resting open circuit potential (OCP), which is the voltage they attain while in contact with an electrolyte, can significantly change the interfacial properties of the metallic surfaces and alter the behavior of the surrounding cells, compromising the biocompatibility of metallic implants. Voltages can also be controlled to modulate cell function and fate. To date, the details of the physico-chemical phenomena and the role of different biomaterial parameters involved in the interaction between cells …

The Impact Of Standards-Based Reform On Special Education: An Exploration Of Westvale Elementary School, Jessica Kim Bacon

Teaching and Leadership - Dissertations

A critical, interpretivist, qualitative study, this project examines how standards-based reform impacts special education at an urban school, called Westvale Elementary School. The school was labeled a Persistently Low Achieving school under the No Child Left Behind Act and was thus required to undergo a "transformation" process. The demographics of the school at the time of the study were: over 95% free and reduced lunch, 40% Limited English Proficiency, and over 20% students with disabilities. The racial makeup of the school is: 50% Hispanic or Latino, 35% Black or African American, and 10% white. My methodological approach drew primarily upon …

PdmsStar-Peg Hydrogels Prepared Via Solvent-Induced Phase Separation (Sips) And Their Potential Utility As Tissue Engineering Scaffolds, B. M. Bailey, R. Fei, Dany J. Munoz Pinto, M. S. Hahn, M. A. Grunlan

Engineering Faculty Research

Inorganic-organic hydrogels based on methacrylated star polydimethylsiloxane (PDMS_star-MA) and diacrylated poly(ethylene glycol) (PEG-DA) macromers were prepared via solvent-induced phase separation (SIPS). The macromers were combined in a dichloromethane precursor solution and sequentially photopolymerized, dried and hydrated. The chemical and physical properties of the hydrogels were further tailored by varying the number average molecular weight (M_n) of PEG-DA (M_n = 3.4k and 6k g mol^-1) as well as the weight percent ratio of PDMS_star-MA (M_n = 7k g mol^-1) to PEG-DA from 0:100 to 20:80. Compared to analogous hydrogels …

Operationalizing Intelligence Dominance, Roy Godson

CIWAG Case Studies

Newer, fragile states often lack the police, administrative, and economic resources needed to govern effectively, and many cannot provide basic goods and services to significant sectors of their population. The vacuum inside these states is being filled by armed groups and political movements that are growing in both numbers and capability. The global competition for power, influence, and legitimacy leads to struggles for control of populations, territory, and resources.

Lines In The Sand: Social Representations Of Substance Use Boundaries In Life Narratives, K. F. Trocki, L. O. Michalak, Laurie A. Drabble

Faculty Publications

This study identifies social representations in interviews about alcohol and substance use in the discourse of 129 young adults, who were interviewed for 2.5 to 3.5 hr each for their life histories and use or nonuse of alcoholic beverages and drugs. Respondents spontaneously delineated their substance use boundaries, creating a continuum of behaviors with boundary points separating acceptable from unacceptable behaviors. They used signaling expressions to indicate go and stop signs and movement along the substance use continuum and reported negotiating substance use boundaries both internally and with peers. A ubiquitous narrative element was the cautionary tale, in which a …

Using Marine Snails To Teach Biogeography And Macroevolution: The Role Of Larvae And Dispersal Ability In The Evolution And Persistence Of Species, Jonathan R. Hendricks

Faculty Publications

While some marine animals are capable of traveling great distances, many have limited mobility as adults and spend the majority of their lifetimes in a small geographical area or may even be cemented to a single place. While it might be expected that species with limited mobility would have small geographic distributions, some nevertheless occur over very large areas. This is the case for some marine snails (gastropods). A key factor that impacts the geographic distribution of marine snails is the type of larvae they have during the phase of their life history that follows hatching from an egg. Because …

The Impact Of Competition In Forensics On Future Careers, Jace Thomas Lux

Dissertations

Each year, thousands of college students participate in forensics (competitive speech and debate). Despite previous studies that identify numerous benefits to forensics participation, the activity is often eliminated from college campuses due to financial constraints. Although previous literature identifies the benefits of forensics participation to competitors, these studies do not address the lasting impact of college forensics participation on the careers of former competitors.

This exploratory study sought to identify the forensics outcomes that former competitors felt are used most frequently in their current careers, as well as the amount of emphasis forensics programs are placing on teaching these particular …

Here, Dr. Daniels‐Sykes explores the principle of religious liberty, which has become one of the focal points in the current health care debate. She considers how one should ‘live’ religious liberty from the perspective those parishioners who live on the margins – those whose parishes have been closed, and the victims of individual and institutional racism.

Differential Expression Of Alpha 4 Integrins On Effector Memory T Helper Cells During Bordetella Infections. Delayed Responses In Bordetella Pertussis, Tzvia Abramson, Tuan M. Nguyen, Dipti Ravindra, Brian Kwong, Sana Waheed, Ryan Ferguson, Nicole Tarlton, Victoria Wu, Christopher S. Sequeira, Martina Bremer

Faculty Publications, Biological Sciences

Bordetella pertussis (B. pertussis) is the causative agent of whooping cough, a respiratory disease that is reemerging worldwide. Mechanisms of selective lymphocyte trafficking to the airways are likely to be critical in the immune response to this pathogen. We compared murine infection by B. pertussis, B. parapertussis, and a pertussis toxin-deleted B. pertussis mutant (BpΔPTX) to test the hypothesis that effector memory T-helper cells (emTh) display an altered pattern of trafficking receptor expression in B. pertussis infection due to a defect in imprinting. Increased cell recruitment to the lungs at 5 days post infection (p.i.) with B. parapertussis, and to …

Digital Storytelling: Reinventing Literature Circles, Maryann Tatum Tobin

Faculty Articles

New literacies in reading research demand the study of comprehension skills using multiple modalities through a more complex, multi-platform view of reading. Taking into account the robust roll of technology in our daily lives, this article presents an update to the traditional literature circle lesson to include digital storytelling and multimedia. Digital Storytelling Circles (DSCs) support the idea of creating a “community of learners” who participate in purpose-driven engagement with text to create meaning. Digital storytelling as an activity is not new to English language arts classes, but this article discusses the versatility of digital storytelling and how DSCs provide …

L’Italiano: Il Passato E Il Presente, Matthew Hamilton

The Kennesaw Tower Undergraduate Foreign Language Research Journal

Through the rise and fall of empires, Italy and its people experienced many changes. The Apennine peninsula has been under the control and influence of many different cultures and kingdoms. One of the greatest impacts is in the language. Italian, as it is known around the world, has very diverse origins. The unified Italian language known as Italian standard introduced by Dante Alighieri, promoted by literature, supported by fascism and spread by newspapers, television and radio is much different than the numerous dialects spoken two hundred years ago. This essay describes the beginnings of the Italian language, but also investigates …

Application Essays As An Effective Tool For Assessing Instruction In The Basic Communication Course: A Follow-Up Study, Joseph P. Mazer, Cheri J. Simonds, Stephen K. Hunt

Publications

The assessment of student learning in general education courses is of critical importance in higher education. This study examines the utility of a writing assignment (application essays) in a basic communication course as an effective assessment tool. The authors conducted a content analysis of student portfolios to determine the extent to which application essays provide evidence of student learning in the basic course. The present study extends the findings from recent assessment efforts (Jones, Simonds, & Hunt, 2005) to explore types of mass media events students address in application essays and assess the revisions made to the assignment based on …
