A Root Cause Analysis Of The Barriers To Transparency Among Physicians A Systemic Perspective, Bianca Perez
A Root Cause Analysis Of The Barriers To Transparency Among Physicians A Systemic Perspective, Bianca Perez
Electronic Theses and Dissertations
Transparency in healthcare relates to formally reporting medical errors and disclosing bad outcomes to patients and families. Unfortunately, most physicians are not in the habit of communicating transparently, as many studies have shown the existence of a large medical error information gap. Research also shows that creating a culture of transparency would mutually support patient safety and risk management goals by concomitantly reducing medical errors and alleviating the malpractice crisis. Three predictor variables are used to represent the various dimensions of the context just described. Perfectionism represents the intrapersonal domain, socio-organizational climate represents the interpersonal and institutional domains, and medico-legal …

Impulsivity And Attention-Deficit/Hyperactivity Disorder (Adhd) Testing Competing Predictions From The Working Memory And Behavioral Inhibition Models Of Adhd, Joseph S. Raiker
Electronic Theses and Dissertations
Impulsivity is a hallmark of two of the three DSM-IV ADHD subtypes and is associated with myriad adverse outcomes. Limited research, however, is available concerning the mechanisms and processes that contribute to impulsive responding by children with ADHD. The current study tested predictions from two competing models of ADHD – working memory (WM) and behavioral inhibition (BI) – to examine the extent to which ADHD-related impulsive responding was attributable to model-specific mechanisms and processes. Children with ADHD (n = 21) and typically developing children (n = 20) completed laboratory tasks that provided WM (domaingeneral central executive [CE], phonological/visuospatial storage/rehearsal) and …
Age-Typing Across Occupations When, Where, And Why Age-Typing Exists, Michael Dennis Reeves
Age-Typing Across Occupations When, Where, And Why Age-Typing Exists, Michael Dennis Reeves
Electronic Theses and Dissertations
The present study sought to determine the direction and degree to which occupations representative of all major occupational categories are viewed as age-typed (i.e., more appropriate for older or younger workers). The 60 occupations examined were the 12 most common and familiar occupations in each of five occupational categories used by the U.S. Census Bureau. I randomly assigned 365 participants to one of three survey conditions. Participants rated the feature centrality, proportional representation, normative age, and optimal performance age of 20 of the 60 occupations and the age-type of 20 different occupations. Results showed that participants reliably rated the occupations …

Estimation For The Cox Model With Various Types Of Censored Data, Tonya Riddlesworth
Electronic Theses and Dissertations
In survival analysis, the Cox model is one of the most widely used tools. However, up to now there has not been any published work on the Cox model with complicated types of censored data, such as doubly censored data, partly-interval censored data, etc., while these types of censored data have been encountered in important medical studies, such as cancer, heart disease, diabetes, etc. In this dissertation, we first derive the bivariate nonparametric maximum likelihood estimator (BNPMLE) F[subscript n](t,z) for joint distribution function F[sub 0](t,z) of survival time T and covariate Z, where T is subject to right censoring, noting …
The Seaside Resort Towns Of Cape May And Atlantic City, New Jersey Development, Class Consciousness, And The Culture Of Leisure In The Mid To Late Victorian Era, Tatyana Ressetar
The Seaside Resort Towns Of Cape May And Atlantic City, New Jersey Development, Class Consciousness, And The Culture Of Leisure In The Mid To Late Victorian Era, Tatyana Ressetar
Electronic Theses and Dissertations
"Victorianism" is a highly controversial, sometimes ironic, term penned by historians throughout various works that has come to hold dramatic weight in both its meaning and its influence. Though the term is usually most closely associated with nineteenth century England, Victorianism was a highly influential movement in American culture simultaneously as well, specifically in the spheres of home, work, and play. Of those, "play," or leisure, is undoubtedly the least explored, especially before the latter decades of the twentieth century. Prior to this period, most literature about the Victorians, with the exception of a few works, only dealt with masculinity, …

The purpose of this thesis is to assess the incidence, demographic prevalence, and general severity of hip and knee OA in a Roman-Christian period (50 A.D – 450 A.D) population sample from the Dakhleh Oasis, Egypt. The bioarchaeological sample originates from the Kellis 2 cemetery which is associated with the ancient town of Kellis. The town of Kellis …
Modeling Human Group Behavior In Virtual Worlds, Fahad Shah
Modeling Human Group Behavior In Virtual Worlds, Fahad Shah
Electronic Theses and Dissertations
Virtual worlds and massively-multiplayer online games are rich sources of information about large-scale teams and groups, offering the tantalizing possibility of harvesting data about group formation, social networks, and network evolution. They provide new outlets for human social interaction that differ from both face-to-face interactions and non-physically-embodied social networking tools such as Facebook and Twitter. We aim to study group dynamics in these virtual worlds by collecting and analyzing public conversational patterns of users grouped in close physical proximity. To do this, we created a set of tools for monitoring, partitioning, and analyzing unstructured conversations between changing groups of participants …

Electronic Theses and Dissertations
This study investigated the literate identities of college students who engage in various school and non-school writing practices simultaneously. In case studies of three student writers, the researcher seeks to explore how the discourse community roles, selfperceptions, negotiation of multiple writing processes and development of authority impacted the students’ identities as writers. Triangulated research methods included weekly interviews with the student participants, observation of the students in their writing classrooms and analysis of the students’ school and non-school texts over one semester. Students experienced several conflicts and synergies between contexts. Main findings indicated that writing across many academic and extra-academic …
The Synergies Between Tourism Expansion And Development An Analysis Of Economic Growth, Poverty And Human Development In Ecuador, Manuel Antonio Rivera
The Synergies Between Tourism Expansion And Development An Analysis Of Economic Growth, Poverty And Human Development In Ecuador, Manuel Antonio Rivera
Electronic Theses and Dissertations
This dissertation attempts to answer the question of what has been the effect of tourism expansion and development in Ecuador. We attempt to analyze, both theoretically and empirically, the relationship between tourism and development. There have been an enormous number of studies explaining how tourism can affect the various dimensions of development. However, no research has been undertaken to simultaneously empirically examine the impact that changes in tourism expansion has on poverty, human development, and economic growth. To this end, we propose a cointergation methodology with an error correction model to estimate the impact of tourism expansion on poverty, human …

Cfd Analysis Of A Uni-Directional Impulse Turbine For Wave Energy Conversion, Carlos Alberto Velez
Electronic Theses and Dissertations
Ocean energy research has grown in popularity in the past decade and has produced various designs for wave energy extraction. This thesis focuses on the performance analysis of a uni-directional impulse turbine for wave energy conversion. Uni-directional impulse turbines can produce uni-directional rotation in bi-directional flow, which makes it ideal for wave energy extraction as the motion of ocean waves are inherently bi-directional. This impulse turbine is currently in use in four of the world’s Oscillating Wave Columns (OWC). Current research to date has documented the performance of the turbine but little research has been completed to understand the flow …

The need for cleaner and more fuel efficient means to produce electricity is growing steadily. Advancements in cooling technologies contribute to the improvements in turbine efficiency and are used for gas turbines and for power generation in automotive, aviation, as well as in naval applications, and many more. Studies introducing turbulators on walls of internal cooling channels, which can be applied to hot gas components and in recuperative heat exchangers, have been reviewed for their ability to promote heat transfer in the channel while observing pressure loss caused by adding the features. Several types of turbulators have been studied; ribs, …
Gender Composition Of Online Technical Communication Collaborations, Erika A. Wardell
Gender Composition Of Online Technical Communication Collaborations, Erika A. Wardell
Electronic Theses and Dissertations
Online collaborations are more prevalent in society due to electronic communication allowing students and professionals to communicate with each other, without needing to spend time or money traveling. The lack of visual cues in electronic communication means writing styles primarily set the tone of a message. A group member‟s gender can affect his or her writing style and what he or she assumes about the message. The differing writing styles and potential gender bias can cause misunderstandings, which delay projects and sometimes lead to ostracizing a group member. The gender composition of an online collaboration, therefore, can have a positive …
Explaining The Support Of The British National Party (Bnp) In The 1999, 2004, And 2009 European Parliament Elections, Jonathan Richard Willis
Explaining The Support Of The British National Party (Bnp) In The 1999, 2004, And 2009 European Parliament Elections, Jonathan Richard Willis
Electronic Theses and Dissertations
In the past decade, there has been a surge of interest in extreme right Western European parties. Well-established parties such as the National Front (FN) in France, Vlaams Belang (formerly Vlaams Blok) in Belgium, and Lega Nord in Italy have been scrutinized. However, extreme right parties that have just recently begun to experience electoral successes such as the British National Party (BNP) have received less evaluation and discussion in the literature. Therefore, this study examines the BNP‟s electoral fortunes in the European elections of 1999, 2004, and 2009. I explore the support for the BNP using the traditional variables of …
Effective Task Transfer Through Indirect Encoding, Phillip Verbancsics
Effective Task Transfer Through Indirect Encoding, Phillip Verbancsics
Electronic Theses and Dissertations
An important goal for machine learning is to transfer knowledge between tasks. For example, learning to play RoboCup Keepaway should contribute to learning the full game of RoboCup soccer. Often approaches to task transfer focus on transforming the original representation to fit the new task. Such representational transformations are necessary because the target task often requires new state information that was not included in the original representation. In RoboCup Keepaway, changing from the 3 vs. 2 variant of the task to 4 vs. 3 adds state information for each of the new players. In contrast, this dissertation explores the idea …
A Laudable Ambition Fired Her Soul Conduct Fiction Helps Define Republican Womanhood, Female Communities, And Women's Education In The Works Of Judith Sargent Murray, Hannah Webster Foster, And Susanna Haswell Rowson, Jessica Crystal Workman
A Laudable Ambition Fired Her Soul Conduct Fiction Helps Define Republican Womanhood, Female Communities, And Women's Education In The Works Of Judith Sargent Murray, Hannah Webster Foster, And Susanna Haswell Rowson, Jessica Crystal Workman
Electronic Theses and Dissertations
This study examines the major works of Judith Sargent Murray, Hannah Webster Foster, and Susanna Haswell Rowson, three major writers of the 1790s whose writing responds to the ideologies of the early American Republic. I suggest that Murray, Foster, and Rowson write conduct fiction which responds to the changing attitudes toward women and education after the American Revolution. Using fiction, these authors comment on the republican woman, the need for women’s education, and the necessity for women to gather in communities for support. Despite the prevailing notion that reading too many novels would corrupt young women, Judith Sargent Murray’s novella, …

Development Of Molecular And Cellular Imaging Tools To Evaluate Gene And Cell Based Therapeutic Strategies In Vivo, Jixiang Xia
Electronic Theses and Dissertations
Molecular imaging modalities are important tools to evaluate the efficacy of gene delivery systems and cell-based therapies. Development and application of these modalities will advance our understanding of the mechanism of transgene expression and cell fate and functions. Physical gene transfer methods hold many advantages over viral vectors among gene therapeutic strategies. Here, we evaluated the efficacy of biolistic (“gene gun”) gene targeting to tissues with non-invasive bioluminescence imaging (BLI) methods. Plasmids carrying the firefly luciferase reporter gene were transfected into mouse skin and liver using biolistics, and BLI was measured at various time points after transfer. With optimized DNA …

Cultural Differences In Forgiveness Fatalism, Trust Violations, And Trust Repair Efforts In Interpersonal Collaboration, Jessica L. Wildman
Cultural Differences In Forgiveness Fatalism, Trust Violations, And Trust Repair Efforts In Interpersonal Collaboration, Jessica L. Wildman
Electronic Theses and Dissertations
Mistakes and betrayals can cause developing interpersonal trust between parties to be broken, and damaged trust can have serious negative impacts on relationships, such as withdrawal from group interaction or the enactment of revenge. Research has suggested that the use of apologies helps to repair damaged trust. However, this research is almost exclusively based in westernized populations and has not begun to explore any cross-cultural differences. Therefore, the primary goal of this comparative cross-national laboratory study was to examine if, and how, the effectiveness of trust repair efforts differs across cultures. The effectiveness of three manipulated trust repair strategies (no …
Integration Of High-Q Filters With Highly Efficient Antennas, Yazid Yusuf
Integration Of High-Q Filters With Highly Efficient Antennas, Yazid Yusuf
Electronic Theses and Dissertations
The integration of high-quality (Q)-factor 3-D filters with highly efficient antennas is addressed in this dissertation. Integration of filters and antennas into inseparable units eliminates the transitions between the otherwise separate structures resulting in more compact and efficient systems. The compact, highly efficient integrated 3-D filter/antenna systems, enabled by the techniques developed herein, allow for the realization of integrated RF front ends with significantly- reduced form factors. Integration of cavity filters with slot antennas in a single planar substrate is first demonstrated. Due to the high Q factor of cavity resonators, the efficiency of the integrated filter/antenna system is found …
Hückel Energy Of A Graph: Its Evolution From Quantum Chemistry To Mathematics, Steven Zimmerman
Hückel Energy Of A Graph: Its Evolution From Quantum Chemistry To Mathematics, Steven Zimmerman
Electronic Theses and Dissertations
The energy of a graph began with German physicist, Erich H¨uckel’s 1931 paper, Quantenttheoretische Beitr¨age zum Benzolproblem. His work developed a method for computing the binding energy of the π-electrons for a certain class of organic molecules. The vertices of the graph represented the carbon atoms while the single edge between each pair of distinct vertices represented the hydrogen bonds between the carbon atoms. In turn, the chemical graphs were represented by an n × n matrix used in solving Schr¨odinger’s eigenvalue/eigenvector equation. The sum of the absolute values of these graph eigenvalues represented the total π-electron energy. The criteria …
Techniques For Boosting The Performance In Content-Based Image Retrieval Systems, Ning Yu
Techniques For Boosting The Performance In Content-Based Image Retrieval Systems, Ning Yu
Electronic Theses and Dissertations
Content-Based Image Retrieval has been an active research area for decades. In a CBIR system, one or more images are used as query to search for similar images. The similarity is measured on the low level features, such as color, shape, edge, texture. First, each image is processed and visual features are extract. Therefore each image becomes a point in the feature space. Then, if two images are close to each other in the feature space, they are considered similar. That is, the k nearest neighbors are considered the most similar images to the query image. In this K-Nearest Neighbor …
Peak Performance Training, Matthew Gabriel Hallett
Peak Performance Training, Matthew Gabriel Hallett
Electronic Theses and Dissertations
Peak performance is defined as an “episode of superior functioning” where an individual performs up to (and sometimes exceeds) their full potential (Privette, 1983, p. 1361). Most individuals do not consistently experience episodes of peak performance. After accounting for biological factors, motivation, and external constraints, the inability to achieve peak performance consistently is due to the challenge of successfully selecting and accessing knowledge and skills on demand while under pressure (Brown, 2009). This thesis describes the psychology of peak performance and skill training for peak performance. A peak performance training program is designed specifically for business professionals. The program was …
