The Influence Of Urban Development Dynamics On Community Resilience Practice In New York City After Superstorm Sandy: Experiences From The Lower East Side And The Rockaways, Leigh Graham, Wim Debucquoy, Isabelle Anguelovski

Publications and Research

While (urban) resilience has become an increasingly popular concept, especially in the areas of disaster risk reduction (DRR) and climate change adaptation (CCA), it is often still used as an abstract metaphor, with much debate centered on definitions, differences in approaches, and epistemological consider- ations. Empirical studies examining how community-based organizations (CBOs) “practice” resilience on the ground and what enables these CBOs to organize and mobilize around resilience are lacking. Moreover, in the growing context of competitive and entrepreneurial urbanism and conflicting priorities about urban (re)development, it is unclear how urban development dynamics influence community- based resilience actions. Through empirical …

Greater New York: The Sports Capital Of Depression Era America, Jeffrey A. Kroessler

Publications and Research

Any history of the Great Depression is incomplete if it neglects sports, and New York City was the unrivaled sports capital of America. From professional baseball to college basketball to boxing, the most important sporting events took place in New York's legendary venues: Yankee Stadium, the Polo Grounds, Madison Square Garden, Forest Hills, and Belmont Park. Sports also mirrored social issues. Joe Louis's boxing matches against white opponents represented more than a simple athletic contest and stimulated racial and ethnic pride, especially in his bouts with Max Schmeling. Long Island University's dominant basketball team boycotted the 1936 Olympic trials to …

The Amino Terminal Region Of Cardiac Myosin Binding Protein-C Is Necessary For Cardiac Function, Thomas Lawrence Lynch

Dissertations

Cardiac myosin binding protein-C (cMyBP-C) is a thick filament-associated protein that has been suggested to regulate cardiac contraction via its amino terminal (N’) region. Following ischemic injury to the heart, cMyBP-C is cleaved into a predominant N’ fragment consisting of domains C0 through C1 and the first 17 residues of the M-domain that is referred to as C0-C1f. However, the necessity of the N’-C0-C1f region of cMyBP-C in regulating cardiac function in vivo has not been elucidated. I hypothesized that the N’-C0-C1f region of cMyBP-C is critical for normal cardiac function in vivo. To test this hypothesis, transgenic (TG) mice …

The Utilization Of Liquid Chromatography Tandem Mass Spectrometry And Related Techniques For The Analysis And Identification Of Emerging Contaminants In Aqueous Matrices, Matthew Reichert

Dissertations

Environmental pollutants can be found in many ecosystems and cover many different compound classes. The Environmental Protection Agency is responsible for monitoring and regulating several of these classes of compounds which daily enter the environment. However, there are still hundreds, if not thousands, of compounds present in the environment which have yet to be regulated or even identified. The discovery and identification of these unknown emerging pollutants is crucial for the prevention of potential human health risks and irreversible ecological damage.

The research presented is divided into two projects. The first part of this research investigates the disinfectant 3-Bromo-1-chloro-5,5-dimethylhydantoin, which …

Habermas And Public Reason In The Digital Age: Technology And Deliberative Democracy, Asaf Bar-Tura

Dissertations

Scholars defending the deliberative model of democracy have focused much of their attention on argumentation and criteria for offering public reasons in deliberative processes, but have paid little attention to the ways in which digital technologies mediate such deliberations. Conversely, critical theorists of technology have emphasized the socially determined nature of technology, but have lacked a theory of democracy through which to normatively assess technologies that mediate public discourse. Through a reworking of Jürgen Habermas’s discourse-based theory of democracy, my research provides a new understanding of the flows of political communication and power in the democratic public sphere and the …

The Impact Of Altered T Cell Receptor—Peptide-Major Histocompatibility Complex Interactions On Antigen Recognition And T Cell Function, Timothy T. Spear

Dissertations

Adoptive cell transfer (ACT) using T cell receptor (TCR) gene-modified T cells is an exciting and rapidly evolving field. Numerous basic science and clinical studies have demonstrated various levels of feasibility, safety, and efficacy using TCR-engineered T cells to treat cancer and viral infections. Genomic instability of targeted diseases, however, requires effective and safe TCRs to cross-recognize mutated antigens while minimizing on- or off-target toxicities. Thus, improvements to T cell-based therapeutics mandate a broader understanding of the principles governing antigen recognition. This dissertation addresses critical biologic questions evaluating which parameters are most important in facilitating antigen recognition, and how alterations …

Inhibition Of B Lymphopoiesis By Adipocytes And Myeloid-Derived Suppressor Cells, Domenick Kennedy

Dissertations

B lymphopoiesis declines with age in humans, mice, and rabbits. Impaired B lymphopoiesis correlates with increased fat in the bone marrow (BM), suggesting that adipocytes negatively regulate this process. In fact, adipocyte factors were found to inhibit B cell development in BM cultures.

Our goal was to understand the mechanism by which adipocytes inhibit B cell development. Through culturing mouse BM cells on OP9 stromal cells in the presence of adipocyte-conditioned medium (ACM), we found that adipocytes promote the accumulation of CD11b+Gr1+ myeloid-derived suppressor cells (MDSCs). These cells were not simply bystanders, as we report for the first time that …

Understanding Challenges And Tradeoffs In Istar Tool Development, Tong Li, Alicia M. Grubb, Jennifer Horkoff

Computer Science: Faculty Publications

Many iStar-based modeling and analysis tools have been developed for specific iStar-related purposes (e.g., tools enumerated in iStar wiki). Despite the proliferation of tools, new tools keep being built, taking resources and time and possibly "reinventing the wheel" in terms of tool functionality. To gain an in-depth understanding of this situation, we are interested in the challenges and tradeoffs in creating iStar tools. In this paper, we examine three diverse tools as case studies, illustrating the challenges and tradeoffs from the developer's perspective. Based on such studies, we establish a goal model to capture the collected knowledge, which can help …

Standardized Assessment Results As A Predictor Of Student Reading Success In New Brunswick, Canada, Gregory David Paterson

Walden Dissertations and Doctoral Studies

Many Canadian school districts use standardized reading achievement data to support reading instruction. Over 30% of 9th-grade students in the Anglophone School District-South (ASD-S) have not met targets for the English Language Proficiency Assessment (ELPA), a graduation requirement in New Brunswick, Canada. This study compared archival reading scores of 6th-grade students from 2009-2012 with the same students' scores in 9th-grade from 2012-2015, to determine if 6th-grade scores were a predictor of 9th-grade results. Rendering the impact illiteracy plays on society, this study applied the theoretical framework of social theory from Bourdieu's (1977, 1984, 1986) view of social mobility and Turner's …

Walden Dissertations and Doctoral Studies

The United States jewelry industry recognized that the illegal import and trade of conflict diamonds is a matter of serious international and national concern, leading to human rights abuse. As such, human rights and conflicts became the primary impetus for establishing the Kimberly Process (KP) and corporate social responsibility (CSR) policies. The purpose of this quantitative study was to investigate the effectiveness of the KP and CSR policies in deterring the use of conflict diamonds in the U.S. jewelry industry. This study was an investigation as to whether conflict diamonds are entering the U.S. jewelry supply chain and a review …

The Impact Of Self-Efficacy On Retention In Technical Colleges, Percy W. Reed

Walden Dissertations and Doctoral Studies

Vocational and career training institutes focus their energy and resources on student support services, increasing student retention as it relates to minority populations. Despite these efforts, a specific vocational and career institute in the southeast United States reports a 50% retention rate of students who are enrolled. This case study explored students' descriptions of how self-efficacy supported their perseverance while attending the vocational and career training institute. The conceptual framework included Bandura's notions of self-efficacy and Tinto's integration model. Purposeful sampling strategies were used to interview 10 successfully-retained students enrolled in their 4th term or beyond at the vocational and …

Meeting Meaningful-Use Requirements With Electronic Medical Records In A Community Health Clinic, Tony Andrew Richardson

Walden Dissertations and Doctoral Studies

Small nonprofit medical practices lack the technical expertise to implement electronic medical records (EMRs) that are consistent with federal meaningful-use requirements. Failure to comply with meaningful-use EMR requirements affects nonprofit community health care leaders' ability to receive reimbursement for care. Complexity theory was the conceptual framework used in this exploratory single case study. The purpose of the study was to explore the strategies nonprofit community health care leaders in Washington, DC used to implement EMRs in order to comply with the meaningful-use requirements. Data were collected via in-depth interviews with 7 purposively-selected health care leaders in a nonprofit clinic and …

The Impact Of Gender And Focal Concerns Theory On The Treatment Of White-Collar Defendants By Federal Judges, Brandon Michael Roberts

Walden Dissertations and Doctoral Studies

Previous research found gender to be a primary consideration of judges in terms of actions towards defendants. Blameworthiness, the combined effect of criminal history, offense severity, and the defendant's role in the criminal event, is also known to impact judge's actions. Little, though, is known about how gender and blameworthiness, combined, may be related to judges' actions towards white-collar defendants. The purpose of this case study, therefore, was to explore whether defendant gender and blameworthiness impact judicial actions towards defendants charged with white-collar crime(s) in a federal district court of New York. The theoretical framework was Demuth and Steffensmeier's theory …

Cultural Relevance In An English Language Learners' Classroom: A Qualitative Case Study, Katherine L. Roe

Walden Dissertations and Doctoral Studies

Colleges and universities typically provide remedial reading coursework for English language learners (ELL) to develop academic reading proficiency. However, a disproportionate number of ELLs fail to exit remedial classes. Prior research has indicated cultural relevance can motivate and stimulate learning; however, the extent to which a culturally relevant classroom curriculum makes a difference in the ELL classroom experience has not been fully explored. This study describes the experience of cultural relevance in an academic reading ELL college class. Moll's funds of knowledge was used as the conceptual framework in a qualitative case study to examine how cultural strengths and knowledge …

A Comparative Study Of Two Instructional Models In Developmental Education Writing Programs, Barbara Ann Roseborough

Walden Dissertations and Doctoral Studies

Low college readiness among high school graduates is a national problem. A significant percentage of graduates are referred to courses designed to remediate deficiencies in the basic skills of reading, writing, and mathematics. Initiatives designed to improve the student experience in remedial and developmental programs have focused on the use of technology. Although technology has been used in the teaching of writing, research has not shown that this method is an improvement when compared to the lecture-based approach to teaching writing. The purpose of this nonexperimental quantitative study was to examine the impact of a technology-based writing program on student …

Teachers' Perspectives: Face-To-Face And Computer-Based Instruction In Math, Carolyn Jones Sessoms

Walden Dissertations and Doctoral Studies

Differentiated instruction offers opportunities to improve student academic performance, specifically in students with learning disabilities. However, teachers' perceptions of which differentiated-instruction program works best to support differently abled students were unknown. The purpose of this qualitative case study was to explore teachers' perceptions on whether face-to-face instruction using response to intervention or computer-based learning using TenMarks works best in improving the academic performance of students who are differently abled in mathematics, specifically geometry. Constructivism, social disability theory, and Bandura's social learning theory formed the study's theoretical framework. Research questions guiding the study focused on teachers' perceptions of the advantages and …

Improving Bedside Swallow Screening In Acute Stroke Patients: An Evaluation Plan, Juliette Segree

Walden Dissertations and Doctoral Studies

A stroke is a life-changing event for a patient and his or her family. The acute stroke patient is at risk for developing aspiration pneumonia, whether silent or overt. Prevention of pneumonia in this population requires timely completion and documentation of the bedside swallow screen to identify those patients at risk for aspiration pneumonia; however, anecdotal data from the emergency department at the site of this project suggested that completion and documentation of the screening were inconsistent. Guided by the quality caring model adopted by the project site as well as the logic model, the aim of this project was …

Improving Machine Changeover/Setup Times By Increasing U.S. Manufacturers' Knowledge Of 5s, Nicole Schra-Martin

Walden Dissertations and Doctoral Studies

Abstract This qualitative case study examined teachers' perceptions that contributed to a lack of

technology integration in their K-8 classrooms. The purpose of the study was to determine why teachers of a K-8 and K-5 school underused or failed to integrate technology to support learning. The theoretical framework for this study was provided by Dewey's constructivist theory, Lave and Wenger's situated learning theory and communities of practice, and Kolb's experiential learning theory principles of teaching and learning. The research questions addressed teachers' perceptions of technology integration as a curriculum strategy and teachers' perceptions of how technology affected professional practices to …

Identifying Leadership Development Needs Of Catholic Secondary Educators, Neil M. Theisen

Walden Dissertations and Doctoral Studies

Current administrators at a Northeast metropolitan area Catholic school have not formally identified the needs that support leadership development for their future and novice administrators. Compounding this problem, an increasing number of Catholic school lay administrators are taking on leadership roles traditionally held by members of religious communities whose membership is steadily declining within the United States. This case study examined the experiences of current administrators to identify leadership development needs for novice and future administrators at a Catholic secondary school. The study's framework was derived from the concepts of leadership succession planning and mentoring. A purposeful sample of 10 …

Outcomes Of Professional Development For Rural Community College Leaders, William Thompson Thompson

Walden Dissertations and Doctoral Studies

To mitigate the loss of experienced administrators, community college leaders create internal grow-your-own (GYO) leadership development programs. Although the purpose of these programs is to ensure institutional efficacy by developing a pipeline of administrative and faculty leaders, little attention has been given to learning about the participants' post-program career advancement over time. Consequently, the value of GYO leadership training for participants is not well known. The purpose of this qualitative case study was to explore the post-program professional development of a group of participants 2 years after completing a rural community college GYO leadership program. The conceptual framework was guided …
