The Stigmatization Of Deathcare Workers, Shannon Rose Simone

Electronic Theses and Dissertations

Research has indicated that Funeral Directors and Embalmers are stigmatized for their work. Studies have shown that, although the decay of dead bodies is a stigmatized process in American culture, these particular deathcare workers are able to shift the focus of their services from the dead to the living. However, there remains a lack of research regarding deathcare workers who are not employed as Funeral Directors or Embalmers— those whose positions are not as obvious to the general public. This research explores how, why, and to what degree stigma is placed on those individuals who spend the majority of their …

Electronic Theses and Dissertations

This thesis investigates the progress of technological development during the interwar period of 1919 to 1939. The interwar period was a time of slashed military budgets and isolationist policies. However, despite political, financial, and organizational handicaps, each branch of the military made significant progress in the development of military technology, and the air corps and navy achieved significantly better results. The reason these two branches were able succeed was through a combination of organizational policy and the development of an overarching goal for their respective branch. Within this thesis, I investigated each of the major military branches during the interwar …

A Comparison Of Paper-Pencil Versus Video-Conferencing Administration Of A Neurobehavioral Screening Test, Tyler Cole Duffield

Electronic Theses and Dissertations

Regardless of the reason, many patients/clients do not have access to face-to-face medical, neuropsychological, or mental health consultation, assessment, or treatment (Cowain, 2001). The term Remote Neuropsychological Assessment (RNA) has been proposed by Browndyke to denote the general use of telecommunication and Internet-based technologies in neuropsychological assessment and practice (as cited in Schatz & Browndyke, 2002). RNA (Telemedicine) offers a plausible, potentially cost-effective solution to individuals in need of medical, neuropsychological, or mental health consultation, assessment, or treatment that are located in geographical areas away from the specialist (Armstrong, 2006; Berman, 2005; Cowain, 2001; Jacobsen, Sprenger, Andersson, & Krogstad, 2003). …

Towards Calibration Of Optical Flow Of Crowd Videos Using Observed Trajectories, Iman K. Elbadramany

Electronic Theses and Dissertations

The need exists for finding a quantitative method for validating crowd simulations. One approach is to use optical flow of videos of real crowds to obtain velocities that can be used for comparison to simulations. Optical flow, in turn, needs to be calibrated to be useful. It is essential to show that optical flow velocities obtained from crowd videos can be mapped into the spatially averaged velocities of the observed trajectories of crowd members, and to quantify the extent of the correlation of the results. This research investigates methods to uncover the best conditions for a good correlation between optical …

Genetically Modified Es Cells Enhance Cardiac Repair And Regeneration In The Infarcted Heart, Carley E. Glass

Electronic Theses and Dissertations

Transplanted embryonic stem (ES) cells following myocardial infarction (MI) contribute to limited cardiac repair and regeneration with improved function. Therefore novel strategies are still needed to enhance the efficacy by which ES cells differentiate into cardiac cell types and inhibit adverse remodeling in the infarcted myocardium. Our studies evaluate whether genetic manipulation of transplanted ES cells employing miR- 1, a pro-cardiac microRNA, and TIMP-1, an anti-apoptotic and anti-fibrotic protein, will enhance cardiac myocyte differentiation, inhibit native cardiac apoptosis, and reduce fibrosis in the infarcted myocardium. Furthermore, we assess levels of associated pro- (caspase-3, PTEN) and anti-(Akt) apoptotic proteins as well …

In 2010, 222 homicides occurred in Baltimore, according to the city‟s homicide map. One hundred and sixty-five were discussed in The Baltimore Sun, the city‟s most-circulated paper. Based on the inclusion or exclusion of particular cases and the manner in which cases were discussed, conclusions can be drawn about the media‟s perception of a case‟s newsworthiness. Specifically, cases with particular details that varied significantly from a “normal” homicide were found to be most newsworthy, determined in part …

Modeling Carbon Allocation, Growth And Recovery In Scrub Oaks Experiencing Aboveground Disturbance, Troy J. Seiler

Electronic Theses and Dissertations

Allocation of assimilated carbon amongst plant metabolic processes and tissues is important to understanding ecosystem carbon cycles. Due to the range of spatio-temporal scales and complex process interactions involved, direct measurements of allocation in natural environments are logistically difficult. Modeling approaches provide tools to examine these patterns by integrating finer scale process measurements. One such method is root:shoot balance, where plant growth is limited by either shoot activity (i.e. photosynthesis) or root activity (i.e. water and nutrient uptake). This method shows promise for application on frequently disturbed systems which perturb aboveground biomass and thus create imbalances in root and shoot …

Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For Reducing Alcohol Use Among High School Students, Janani Sivasithamparam

Electronic Theses and Dissertations

Alcohol use is the single most alarming behavior among youth in the United States. Adolescents especially are at risk for increases in heavy episodic drinking and drunkenness leading to alcohol-related problems such as academic failure, interpersonal violence, risky sexual behavior and death. In an effort to address this endemic issue, a number of alcohol use prevention programs have been developed and are currently implemented in the high school setting. Many of these programs, however, lack an empirical basis and have been unable to demonstrate significant reductions in alcohol use over time. The need for the development and dissemination of effective …

Translocation Of The Cholera Toxin A1 Subunit From The Endoplasmic Reticulum To The Cytosol, Michael Prentice Taylor

Electronic Theses and Dissertations

AB-type protein toxins such as cholera toxin (CT) consist of a catalytic A subunit and a cell-binding B subunit. CT proceeds through the secretory pathway in reverse, termed retrograde trafficking, and is delivered to the endoplasmic reticulum (ER). In order for the catalytic A1 subunit to become active it must separate from the rest of the holotoxin, and this dissociation event occurs in the ER lumen. CTA1 assumes an unfolded conformation upon dissociation from the holotoxin and is recognized by ERassociated degradation (ERAD), a quality control system that recognizes and exports misfolded proteins to the cytosol for degradation by the …

Investigating The Optimal Presentation Of Feedback In Simulation-Based Training An Application Of The Cognitive Theory Of Multimedia Learning, Wendi Van Buskirk

Electronic Theses and Dissertations

There are many different training interventions that can be used in simulation based training systems (e.g., cueing, hinting, highlighting, deliberate practice, etc.). However, the most widely used training intervention in the military is feedback, most often presented in the form of a debrief. With advances in technology, it is possible to measure and diagnose performance in real-time. Thus it is possible to provide immediate feedback during scenarios. However, training systems designers should not consider the timing of feedback in isolation. There are other parameters of feedback that must also be considered which may have an impact on performance. Specifically, feedback …

A Phenomenological Investigation Of Counseling Students' And Practicum Supervisors' Experiences With The Counselor Competencies Scale, David L. Ascher

Electronic Theses and Dissertations

Counselor educators are charged with facilitating the development of counseling students towards becoming ethical and competent counselors (American Counseling Association [ACA], 2005; Council for Accreditation for Counseling and Related Educational Programs [CACREP], 2009). In addition, counselor educators serve as gatekeepers for the profession and deny entry to counseling students who demonstrate deficiency of necessary competencies (ACA, 2005; Association for Counselor Education and Supervision [ACES], 1993; CACREP, 2009). Numerous assessment tools utilized for the evaluation of counseling competencies have been developed, yet none has gained universal acceptance in the field of counselor education. The Counseling Competencies Scale© (CCS, UCF Counselor Education …

Electronic Theses and Dissertations

Foreign aid aims to improve economic conditions and quality of life in developing countries. The literature on the efficacy of foreign aid to date has been inconclusive; yet there is some evidence that institutional factors may condition the relationship between aid and development. This research focuses on the effects of foreign aid on development, taking into consideration the effects of political institutional factors as intervening in the connection between aid and development. Specifically, this study considers the effects of democracy (political rights and civil liberties) and level of corruption on the relationship between aid and development in sub-Saharan Africa. Development …

The Origins Of Lactase Persistence And Ongoing Convergent Evolution, Beth A. Keller

Electronic Theses and Dissertations

As a primary factor in human evolution, natural selection is an important component of genetic research. Studies of lactase persistence suggest that positive selection has played a powerful role in the adaptation to a lifelong consumption of fresh milk. Using multiple research studies of lactase persistence and suspected corresponding single nucleotide genetic polymorphisms, this study combines data sources to determine whether evidence exists for natural selection of a specific cytosine-to-thymine genetic mutation located 13,910 base pairs (T-13910) upstream from the lactase gene. This polymorphism has potential to be a causal element for lactase persistence, and data suggest that natural selection …

A Comparison Of Stimuli Presentation In Advanced Theory Of Mind Tasks For Adolescents With Asperger's Syndrome (As), Juliet N. Leon

Electronic Theses and Dissertations

Individuals diagnosed with Asperger‟s Syndrome (AS) have marked impairments in social interaction, including difficulty expressing and perceiving thoughts, emotions, and intentions. This deficit may be due in part to a delayed or underdeveloped Theory of Mind (ToM). The previous research investigating ToM in individuals with AS has been inconclusive. The purpose of this study was to compare three Theory of Mind (ToM) tasks, presented via three different modalities, to evaluate the recognition of complex emotions and mental states in adolescents with AS compared to typically developing adolescents. Participants in this study included twenty adolescents: 10 adolescents with AS and 10 …

The Effectiveness Of Teaching Methods Designed To Improve Student Engagement And Retention Of Physics Subject Matter For Both Science And Non-Science Majors, Dan Maronde

Electronic Theses and Dissertations

The necessity of students’ engagement with the subject matter for successful learning is welldocumented in education research in general, and in physics education research in particular. This study examines the merits of two different programs designed to improve student learning through enhanced student engagement with the material. The target populations of the two programs are different: One is the group of students taking a physical science class as part of the general curriculum required of non-science, non-engineering majors; the other is the group of students, mostly in engineering disciplines, who must take the calculus-based introductory physics sequence as part of …

In The Process Of Becoming The Organizational Culture Of The Metropolitan Academic Library, Michael Jason Martin

Electronic Theses and Dissertations

Organizational culture may be defined as the shared norms, values, and beliefs of an organization. The culture expresses itself through symbols and sagas. Organizational culture shapes the behavior of those within the organization and provides a lens through which its members can interpret reality. This study sought to define the organizational culture of the Metropolitan Academic Library. The study was guided by Schein‘s five levels of cultural assumptions: assumptions about external adaptation issues; assumptions about internal integration; assumptions about the nature of truth and reality; assumptions about the nature of time and space; and assumptions about human nature, activity, and …

Design, Fabrication, And Testing Of High-Transparency Deep Ultra-Violet Contacts Using Surface Plasmon Coupling In Subwavelength Aluminum Meshes, Clarisse Mazuir

Electronic Theses and Dissertations

The present work aims at enhancing the external quantum efficiencies of ultra-violet (UV) sensitive photodetectors (PDs) and light emitting diodes (LEDs)for any light polarization. Deep UV solid state devices are made out of AlGaN or MgZnO and their performances suffer from the high resistivity of their p-doped regions. They require transparent p-contacts; yet the most commonly used transparent contacts have low transmission in the UV: indium tin oxide (ITO) and nickel-gold (Ni/Au 5/5 nms) transmit less than 50% and 30% respectively at 300 nm. Here we investigate the use of surface plasmons (SPs) to design transparent p-contacts for AlGaN devices …
