Employee engagement is vital to the business sustainability of an organization. The purpose of this qualitative single case study was to explore successful strategies that business leaders of a service organization used to increase employee engagement. The conceptual framework guiding this study was the behavior engineering model theory developed by Gilbert. A purposeful sample of 6 engineering managers was selected based on their success in creating strategies resulting in increased employee workplace engagement in a monopoly service organization in Connecticut. Semistructured …

Effect Of Vocabulary Test Preparation On Low-Income Black Middle School Students' Reading Scores, Ingrid Nadia Mitchell

Walden Dissertations and Doctoral Studies

Black middle school students in the United States perform poorly on standardized reading achievement tests in comparison to other racial and ethnic groups. The purpose of this study was to examine the effectiveness of a vocabulary-focused test preparation program for underachieving Black middle school students. Thorndike's concept of test-wiseness, a test-taking capacity, provided the theoretical foundation for the study. Research questions investigated the difference in reading test scores on the Discovery Education Assessment of underachieving Black middle school students who participated in a key vocabulary test preparation program and those who did not. An intact-group comparison was used in which …

Improving Communication Between Cancer Patients And Providers During A 15-Minute Office Visit: A Systematic Review Of The Literature, Dr. Tammy Elizabeth Manganelli

Walden Dissertations and Doctoral Studies

Patients undergoing chemotherapy treatments for cancer often experience adverse side effects, including cognitive deficits. These deficits impact the patient's ability to communicate effectively with their oncology provider. Ineffective communication can adversely affect patient outcomes and decrease patient-provider satisfaction. The resulting poor communication can contribute to poor patient outcomes. This systematic literature review focused on assistive communication tools that could be used in an outpatient oncology setting to improve patient-provider communication. The literature review findings led to the development of a resource for providers that includes 15 communication tools that can be used to assess and improve communication in cancer care. …

Teachers' Perceptions Of African American Middle School Girls' Interest In Mathematics And Science, Bonnie Marie Best

Walden Dissertations and Doctoral Studies

Research into African American female underrepresentation in science, technology, engineering, and mathematics (STEM) fields has become an area of interest due to the fact that a majority of African American middle school females do not possess the high levels of mathematics and science knowledge because of social and cultural barriers both inside and outside school that challenge their academic success. The purpose of this qualitative interpretative phenomenological study was to explore teachers' shared, lived experiences of teaching mathematics and science to African American middle school girls. Delgado and Stefancic's critical race theory, Pratt-Clarke's critical race feminism, and Baker-Miller's relational-cultural theory …

Senior Army Women's Leader Behaviors And Their Civilian Career Transition, Sharon R. Hamilton

Walden Dissertations and Doctoral Studies

Female retired Army colonels (FRACs) have significant potential to contribute to civilian organizations. To take advantage of that talent, it is important to have a better understanding of their behaviors based on their dual identities as women and leaders. The purpose of this qualitative case study was to understand the under researched factors accounting for the development of FRACs' leader behaviors and the transfer of those behaviors to civilian careers. The 4 underlying meta categories of leadership behavior formed the conceptual framework. The theory of planned behavior was used to explore potential influences on FRAC leader behavior development. The 3 …

Integrated Groundwater Management: An Overview Of Concepts And Challenges, Anthony J. Jakeman, Olivier Barreteau, Randall G. Hunt, Jean-Daniel Rinaudo, Andrew Ross, Muhammad Arshad, Serena H. Hamilton

Research outputs 2014 to 2021

Managing water is a grand challenge problem and has become one of humanity’s foremost priorities. Surface water resources are typically societally managed and relatively well understood; groundwater resources, however, are often hidden and more difficult to conceptualize. Replenishment rates of groundwater cannot match past and current rates of depletion in many parts of the world. In addition, declining quality of the remaining groundwater commonly cannot support all agricultural, industrial and urban demands and ecosystem functioning, especially in the developed world. In the developing world, it can fail to even meet essential human needs. The issue is: how do we manage …

Research outputs 2014 to 2021

This paper explores the perceptions of first year Business students to embedding sessions and additional support workshops offered through a collaboration between learning advisors and lecturers in a first year foundational unit. Through a social constructivist lens and utilising action research methods, questionnaires (n = 42) were administered to two cohorts of students at the conclusion of the unit in 2011 and 2012 to explore firstly, whether or not they perceived the embedding sessions to be of benefit and, secondly, whether having the learning advisor in the class made them more likely to utilise additional support outside class time. In …

Personal Property Servitudes On The Internet Of Things, Christina Mulligan

Georgia Law Review

Small appliances such as thermostats, watches, jewelry, and eyewear are now being made available with networking capability. These networked objects make up the growing Internet of Things-pieces of personal property that run software and connect to the global Internet. These products are typically governed by terms of service or end-user license agreements that create restrictions on how products can be used or transferred- restrictions which would be unenforceable if the inside of the product consisted of gears rather than processing chips. This Article explores the question of when use and transfer restrictions should be enforceable on networked appliances and other …

Underwriting Sustainable Homeownership: The Federal Housing Administration And The Low Down Payment Loan, David Reiss

Georgia Law Review

The United States Federal Housing Administration (FHA) has been a versatile tool of government since it was created during the Great Depression. The FHA was created in large part to inject liquidity into a moribund mortgage market. It succeeded wonderfully, with rapid growth during the late 1930s. The federal government repositioned it a number of times over the following decades to achieve a variety of additional social goals. These goals included supporting civilian mobilization during World War II; helping veterans returning from that war; stabilizing urban housing markets during the 1960s; and expanding minority homeownership rates during the 1990s. It …

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 …

Column: Nonconventional Civil War Fiction, David Madden

Civil War Book Review

One of the first and still considered one of the finest major Civil War novels, Miss Ravenel’s Conversion from Secession to Loyalty, appeared as early as 1867, was written by a Yankee officer who was an eyewitness, John William De Forest, and was set more on a Louisiana plantation than on a b....

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 …

Effectiveness Of The Kimberley Process And Corporate Social Responsibility In The U.S. Jewelry Industry, Robert Previti

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 …

College Transition Experiences Of Homeschooled Women, Jeanine L. Sanclemente

Walden Dissertations and Doctoral Studies

During the past 40 years, the U.S. homeschooling population rose exponentially. The results of homeschooling need to be studied further so that parents, legislators, and higher education leaders can make prudent and well-informed decisions regarding homeschooled students. No studies have been completed that focus on the unique experiences of homeschooled women as they transition to college in terms of academics, forming new relationships, and individuating from their families. The purpose of this phenomenological study was to explore academic and relational processes during the transition to college. In this qualitative dissertation based on constructivist design and in the conceptual framework of …

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 …
