Exploring Sense Of Community And Persistence In The Community College

Randall Bengfort
As concern grows about the level of college completion in the U.S., higher education leaders are seeking ways to help more students attain their educational objectives. This study sought to aid that effort by determining if a theoretical framework of sense of community developed by McMillan and Chavis (1986) influences students' decisions to persist in their academic studies. The study also explored factors thought to enhance sense of community and persistence. Research has found strong...

An Exploratory Analysis Of Attitudes Toward Religious Help-Seeking Among African-American Christians

Kimberly Michelle Hardy
This dissertation used an exploratory, cross-sectional research design to: (1) understand African-American Christians' attitudes toward religious and professional help-seeking; (2) understand whether or not African-American Christians are seeking help from their church leaders to assist in the amelioration of serious personal and/or mental health issues in lieu of mental health professionals; and (3) understand the dynamics of the religious help-seeking relationship.

Racial/Ethnic Patterns Of Psychotropic Medication Use In Medicaid-Insured Youth

Aloysius Chukwunonye Ibe
In 2003, the Institute of Medicine reported that racial/ethnic disparities in mental and behavioral problems hinder the nation's effort to improve overall health, mostly because of the risk of poorer health status and lower levels of access to healthcare in non-whites compared with white Americans. Earlier studies have shown that African American and Hispanic youth are significantly less likely to be prescribed psychotropic medications than white youth with Medicaid insurance. Aim 1 of this study...

Improving Outpatient Follow Up for Hypertensive Patients Post Emergency Department Visit Using a Staff Education and Telephone Referral Intervention

Jordan Braniff
Problem Statement: Americans are increasingly using the Emergency Department (ED) for primary treatment of hypertension, a significant chronic health problem which requires primary care follow-up. Previous studies have shown that between 24-50% of ED patients are lost to ambulatory follow-up. Purpose: The purpose of this DNP project was to determine if primary care provider (PCP) follow-up and utilization rates increased in patients with hypertension who did not have a PCP after receiving an educational intervention...

A Framework System To Connect Children With Nearby Nature

Roberta Marmer McConochie
Arguably the most savvy of any generation, today's children reside in a state of "Nature Deficit Disorder" (Louv (2005). Though programs approach the problem, children's current condition presents challenges beyond those of landscape architecture and allied professional practices. Currently, there is no comprehensive system to address the full range of children's developmental needs, nor to integrate needs with specific local resources. This thesis develops such a system, a framework to connect children and nature. Input...

Massera-Type Results For CN -Almost Automorphic Solutions Of Some Differential Equations

Valerie N. Nelson
We are concerned with the existence of C(n)-almost automorphic solutions of the equation (1) x'(t) = A(t)x(t) + f(t) where A(t) is a τ-periodic operator and f is C(n)-almost automorphic. In 1950, Massera proved that if the equation (2) x'(t)=Ax(t) + f(t) where f(t) is periodic and A is a constant n x n matrix, has a bounded solution on R+, then it has a periodic solution on all of R. This result has since...

Entity Type Recognition for Heterogeneous Semantic Graphs

Jennifer Sleeman, Tim Finin & Anupam Joshi
We describe an approach for identifying fine-grained entity types in heterogeneous data graphs that is effective for unstructured data or when the underlying ontologies or semantic schemas are unknown. Identifying fine-grained entity types, rather than a few high-level types, supports coreference resolution in heterogeneous graphs by reducing the number of possible coreference relations that must be considered. Big Data problems that involve integrating data from multiple sources can benefit from our approach when the data's...

North Avenue's current condition is that of necessary revitalization, through asset management and the introduction to a wider array of modes other than dominating the automobile. By advancing the roadway to a street where all users,...

Bridging the divide between neuroprosthetic design, tissue engineering and neurobiology

Jennie B. Leach, Anil Kumar H. Achyuta & Shashi K. Murthy
Neuroprosthetic devices have made a major impact in the treatment of a variety of disorders such as paralysis and stroke. However, a major impediment in the advancement of this technology is the challenge of maintaining device performance during chronic implantation (months to years) due to complex intrinsic host responses such as gliosis or glial scarring. The objective of this review is to bring together research communities in neurobiology, tissue engineering, and neuroprosthetics to address the...

Organizational Socialization Of Community College Adjunct Faculty: A Correlational Analysis Of Content, Context, And The Dimensions Influencing Socialization Outcomes

Wanda Lindsey-Lipford
This quantitative study focuses on the socialization processes of the adjunct faculty at three Mid-Atlantic community colleges. Although adjunct faculty are the majority faculty at community colleges, they are still considered as a marginalized group (transient workers) that diminishes the integrity of quality educational programs (Cohen & Brawer, 2008). Hiring adjunct faculty is a debatable issue among researchers; however, the consensus is that if these professionals are hired, they should be socialized into college culture...

This study was framed and guided by three bodies of literature: literature in support of the theory of change, adult learning theory, and effective STEM professional development. The study, designed to be collaborative in nature, employed an action research variation of participatory classroom action research,...

WAVE PROPAGATION IN TENSEGRITY AND PERIODIC STRUCTURES

Mohamed Salem Raafat
This dissertation focuses on the development of the fundamental understanding of the dynamic behavior of assemblies of periodic arrays of tensegrity unit cells (along one and two directions). The ultimate aim of the dissertation is to capitalize on the attractive attributes of tensegrity structures with the unique characteristics of periodic structures, which stem from their ability to impede the propagation of disturbances that fall within certain frequency bands (known as stop bands or bandgaps). A...

Perceived Preparedness And Preparedness Behavior For Terrorism And Natural Disasters Among Low-Income African Americans In Maryland

Myrtle Evans-Holland
Marginalized groups, the poor, and minorities suffer disproportionately by disasters where inequities are more evident during the response and recovery stages. Although there are differences in disaster preparation behaviors between majority and minority ethnic populations, minority populations experience the inequities because of low incomes and other limited resources needed to lessen the impact of a disaster. Furthermore, scientific knowledge about differences in disaster preparedness behavior within racial/ethnic groups is limited. To address the limitation, this...

Examining The Relationship Between Program Support And Adherence To Highly Active Anti-Retroviral Therapy (Haart) In Kenya And Zambia: The Role Of Art Knowledge On This Relationship

Lateefah Hughes
Highly Active Antiretroviral Therapy (HAART) adherence is critical to slowing down reproduction of the AIDS virus and ensuring viral load suppression in people living with the disease. Few studies have assessed how well comprehensive structured treatment programs eliminate disparities in treatment outcomes, and positively influence a person's ability to adhere to HAART. This cross-sectional study examined the effect of program support, patient knowledge about HIV and HAART, and patient physical and behavioral factors on adherence...

On the Validity of the Girsanov Transformation Method for Sensitivity Analysis of Stochastic Chemical Reaction Networks

Ting Wang & Muruhan Rathinam
We investigate the validity of the Girsanov Transformation (GT) method for parametric sensitivity analysis of stochastic models of chemical reaction networks. The validity depends on the likelihood ratio process being a martingale and the commutation of a certain derivative with expectation. We derive some exponential integrability conditions which imply both these requirements. We provide further conditions in terms of a reaction network that imply these exponential integrability conditions.

Evaluation Of The Presentation Of Network Data Via Visualization Tools For Network Analysts: Comparison Of Node-Link, Parallel Coordinates And Tabular Displays

Renee Etoty
Computer Network Defense (CND) analysts require tools that give accurate and current data information about the state of security for the networks they monitor. These reports of data usually generated by Intrusion Detection Systems (IDS) such as the U.S. Army Research Laboratory (ARL)'s Interrogator have traditionally been presented to the analysts via a tabular visual representation on a display. The increasing data fusion from myriad heterogeneous distributed network sensors requires visual displays that can effectively...

An Intersectional Definition of Fairness

James Foulds & Shimei Pan
We introduce a measure of fairness for algorithms and data with regard to multiple protected attributes. Our proposed definition, differential fairness, is informed by the framework of intersectionality, which analyzes how interlocking systems of power and oppression affect individuals along overlapping dimensions including race, gender, sexual orientation, class, and disability. We show that our criterion behaves sensibly for any subset of the set of protected attributes, and we illustrate links to differential privacy. A case...
