Dirty Eddie's War: Based on the World War II Diary of Harry "Dirty Eddie" March, Jr., Pacific Fighter Ace
Dirty Eddie’s War is the true account of the war-time experiences of Harry Andrew March, Jr., captured by way of diary entries addressed to his beloved wife, Elsa. Nicknamed “Dirty Eddie” by his comrades, he served as a member of four squadrons operating in the South Pacific, frequently under difficult and perilous conditions. Flying initially from aircraft carriers covering the landings at Guadalcanal in August 1942, he was one of the first pilots in the air over the island and then later based at Henderson Field with the “Cactus Air Force.” When he returned to combat at Bougainville and the “Hot Box” of Rabaul, the exploits of the new Corsair squadron “Fighting Seventeen” became legendary. Disregarding official regulations, March kept an unauthorized diary recording life onboard aircraft carriers, the brutal campaign and primitive living conditions on Guadalcanal, and the shattering loss of close friends and comrades. He captures the intensity of combat operations over Rabaul and the stresses of overwhelming enemy aerial opposition. Lee Cook presents Dirty Eddie’s story through genuine extracts from his diary supplemented with contextual narrative on the war effort. It reveals the personal account of a pilot’s innermost thoughts: the action he saw, the effects of his harrowing experiences, and his longing to be reunited with the love of his life back home.
Dirty Jokes and Fairy Tales: David Mamet and the Narrative Capability of Film
David Mamet is best known as a playwright, but he also has a thriving film career, both as screenwriter and as director. He has taken very seriously each of these roles, formulating theories that, he suggests, account for the creative choices he makes. Though Mamet sometimes contradicts himself, as when he suggests that viewers should have the satisfaction of constructing their own meaning of a work, but at the same time is devoted to montage, which works by juxtaposing images that lead to a single interpretation, he clearly sees the story as a critical avenue into the spectator's unconscious, where he hopes it will resonate with a truth that speaks directly to the individual. His films House of Games, Things Change, and Homicide clearly reflect his ideas on the best ways of conveying a story on film. In House of Games, Mamet draws on Bruno Bettelheim's theories to construct a fairy tale designed to act on adult viewers in the same way that fairy tales act on the child. In Things Change, he creates a fable that explores issues of friendship and honor within the milieu of the gangster genre. And in Homicide, Mamet uses the expectations viewers bring to the theatre in anticipation of a genre film to explore themes of loyalty and identity. In Oleanna, however, Mamet relies heavily on exposition and dialogue, rather than the visual elements that separate the film from drama, which renders the film the antithesis of his long-held philosophy of film narrative. Mamet's best film work, in House of Games and Homicide, has been innovative and thought-provoking, bringing depth to the new noir and redefining the cop film. His work in Oleanna, though it may prove to be an anomaly, may suggest a surrender of his principles of filmmaking or a reformulation of …

"I disappear in this whole big world": Re-storying the Bearers of Music Culture in the U.S. Academy
Current practices in music education parallel the expansion of globalization and cross-cultural contact. However, the multicultural music education movement—referred to by some as "world music education"—has been primarily about the diversity of musical experiences and less about the circumstances and processes of the music itself. As a result, Western music educators often neglect inseparable learning pathways and unintentionally distort the meaning and value of diverse musics from around the world. While there is considerable research examining the teaching and learning of diverse music cultures, significant portions of that literature only represent the observed accounts of cultural outsiders. In this study, I examined the lived experiences of world music culture bearers who teach in Western university institutions in the Southwest region of the United States. I used narrative inquiry to learn more about their pedagogical experiences and documented their storied accounts of interactions with university students. I based the theoretical framework in this study on Clandinin and Connelly's narrative inquiry three-dimensional space model and Schippers' twelve continuum transmission framework. My primary findings revealed that teaching in a cross-cultural setting involves several musical and contextual choices. Moreover, the perceived authenticity of the research participants' transmission processes was often a byproduct of their teaching realities—the intersection of their music culture and Western institutional structures—and included numerous adaptations. As was the case with all three participants, their past experiences constituted their present teacher knowledge and became a significant part of how they perceived their futures.

Disaster Experience and Self-efficacy As Factors Influencing Emergency Planning in Community-dwelling Older Adults
This study design was to identify and examine how disaster experience, self-efficacy, and demographic factors influence disaster preparedness in community-dwelling older adults. Current data indicates the United States is rapidly aging. Parallel to this significant increase among the elderly population, natural disasters are more prevalent. Consequently, older adults are affected adversely by these disasters and exposure to social vulnerabilities during the disaster cycle. For the purpose of this study, non-identifiable secondary data were analyzed. Sources of the data were the 2007 and 2008 National Center for Disaster Preparedness surveys. The sample focus of this study was adults 50 and older. Regression analyses identified important predictors of disaster preparedness in the survey respondents. Sample adults with previous disaster experience are two times more likely to be in a higher category for having an emergency plan than those respondents with no observable effects of self-efficacy and no previous disaster experience. The frequency of natural disasters in the United States has generated a renewed interest in disaster management, in particular, disaster preparedness. Nevertheless, the focal point of disaster preparedness is no longer the rudimentary stockpile of water, a first aid kit, and a battery operated radio. To advance the field of disaster management it is vital for gerontologist to approach disaster preparedness by differentiating between stockpiling supplies and social cognitive interventions that fundamentally alters preparedness behavior.

Disaster Preparedness: A Procedure Manual for a Nursing Home
Disaster or emergency situations have the potential for serious impact on the safety and security of both residents and staff in a nursing home. Furthermore, federal and state laws require that all nursing facilities be prepared in case of an emergency or disaster. The first part of this document is an introduction and rationale for the development of a nursing home disaster plan. The second part is a procedure manual developed for a nursing home in Oklahoma, outlining emergency actions and recovery procedures for various types of disasters, followed by a list of emergency telephone contacts of key personnel and services both inside and outside the nursing facility.
Disaster Preparedness in Escambia County Florida: The Influence of Oral Narratives
This work addresses hurricane preparedness in Escambia County, Florida. It explores preparing for hurricanes as an informal learning process occurring within personal networks and embedded in beliefs, values, and attitudes. Findings reveal that participants learned to prepare from their parents in childhood and improved upon that knowledge through direct experience in adulthood. Later, they passed this knowledge on to their children as well as co-workers. These preparations are embedded in beliefs of self-determination and attitudes of endurance. However, this body of knowledge and their respective practices are not equally accessible to all. Recommendations are provided so local organizations can incorporate local knowledge and practices with preparedness improvement efforts and foster social cohesion as well.
Disasters, Smart Growth and Economic Resilience: An Empirical Analysis of Florida Cities
This dissertation examines the relationship between economic resilience, disaster experience, and smart growth policies at the local government level. The study is based upon three research questions that examine spatial distribution of economic resilience in Florida cities, and examines the impact of disaster experience, and smart growth policies adopted by local governments on economic resilience. Based upon the bounce-forward approach (Cowell, 2013; Klein et al. 2003), economic resilience is defined using three dimensions—economic stability, economic equity, and economic diversity. The spatial analysis is conducted by mapping economic resilience scores across 780 Census Designated Places in Florida through standard deviation method of classification, and conducting cluster-outlier analysis. Results suggest difference in economic resilience within coastal and inland communities—with higher scores mostly situated inland. East Central Florida, Tampa Bay, and South Florida were identified as high economic resilience clusters, and Northwest Florida was identified as low resilience cluster. Impact of disaster experience, and smart growth policies on economic resilience was examined based upon logic of focusing events by Birkland (1997, 2010). Data was collected from the U.S. Census, the National Climatic Data Center, and the Energy Sustainable Florida Communities Survey conducted by Florida State University in 2009. Results suggest significant association between disaster experience of communities and their level of economic resilience, highlighting the importance of community learning in building capacity for resilience after disasters. The results also highlight the need of balancing mitigation and adaptation strategies. Mixed-use development policies, green building certification, and energy savings policies were found to have a significant positive impact on economic resilience.
Discipline-Based Art Education as the Structural Support of a Language-Arts Intervention Program: Documentation of Cognitive Changes in Certain Elementary-Age Students
This study follows the progress of 11 elementary students who exhibited similar language-arts deficiencies and were treated with traditional and non-traditional language-arts remediation methods. Non-traditional methods were exclusively Discipline-Based Art Education (DBAE) lessons that required students to observe, talk about, and write about art images using a DBAE framework. Portfolios maintained by the students during one complete school year included writings and art production. Writings were marked using a color-coding system developed for the research project and designed to track growth in art cognition. Interviews for affective measure and the Test of Non-Verbal Intelligence, Edition II were administered as pre- and post-tests. Evidence indicated art understanding improved as cognition in language arts improved. Change in attitudes toward art and artists demonstrated a slight positive change. No significant difference was detected in non-verbal intelligence.
Disclosure and its Perceived Impact as Mediators of the Long-Term Consequences of Child Sexual Abuse
The primary purpose of the present study was to investigate factors associated with childhood sexual abuse which mediate long-term effects. Of particular interest were the mediators of disclosure and its perceived impact, as well as variables related to the severity of the abuse. Also of interest were impact areas related to a history of molestation which have received little attention in the literature. Five hundred and seventy-five female undergraduates completed an extensive questionnaire with measures of family background, childhood and adult sexual experiences, health status, and psychological variables. Of these subjects, 286 reported at least one incident of child sexual abuse. It was hypothesized that those females with histories of sexual abuse who received a positive response to their disclosure of abuse would demonstrate more adaptive adult functioning as compared to those victims receiving a negative response, or those who never disclosed. Significant differences were not detected among the three groups on the outcome measures. A number of reasons were explored for why these differences may not have been detected in the present investigation. Although differences were not detected for disclosure status, significant differences were detected between females reporting a history of child sexual abuse and those reporting no abuse on all of the outcome measures. Specifically, sexual abuse victims were more likely than nonvictims to be sexually revictimized in adulthood. Potential explanations for this finding were explored in a discriminant function analysis predicting revictimization status. Further, abused females had significantly higher levels of depression, dissociation, and perceptual disturbances when compared to their nonabused peers. Sexual abuse victims also reported more health symptoms across various bodily systems and had more negative attributions about their physical health status. Differences between the abused and nonabused groups on levels of perceptual disturbance and perceived physical health status are particularly noteworthy since previous research …
Disclosure Habits After Near-Death Experiences: Influences, Obstacles, and Listener Selection

Discourse Indicative of Computational Thinking within a Virtual Community
This study explores the phenomenon of computational thinking indicated by the use of Bloom's taxonomy's cognitive domain verbs in the Scratch community, the online, collaborative environment for the Scratch Visual Programming Language (VPL). A corpus of 660,984 words from three Scratch community sub-forums provide the data for this study. By semantically aligning cognitive domain verbs of Bloom's revised taxonomy to computational thinking (CT) dimensions, the occurrences of the verbs in Scratch community sub-forums are used to indicate instances of computational thinking. The methodology utilizes qualitative coding and analysis with R® and RStudio®. The findings show language attributes such as expressions of imagination, sharing of creative details, collaborative development ideas, teaching, modeling, innovating, solutions focused, and technical support to be indicative of computational thinking and CT dimensions. The computational thinking dimension referred to as computational perspectives occurs most frequently within Scratch community participant discourse. The environmental factors found to contribute to computational thinking and the CT dimensions are supporting tools, personalized learning, supportive organizational culture, social learning, and organizational support. Common among the three computational dimensions is the contributing environmental factor described as supportive organizational culture, with the computational perspectives dimension prevailing among the corpora. The characteristics of computational perspectives and supportive organizational culture suggest a desire for human connection in the attainment of technological skills and knowledge.

Discovering a Descriptive Taxonomy of Attributes of Exemplary School Library Websites
This descriptive study examines effective online school library practice. A Delphi panel selected a sample of 10 exemplary sites and helped to create two research tools--taxonomies designed to analyze the features and characteristics of school library Websites. Using the expert-identified sites as a sample, a content analysis was conducted to systematically identify site features and characteristics. Anne Clyde's longitudinal content analysis of school library Websites was used as a baseline to examine trends in practice; in addition, the national guidelines document, Information Power: Building Partnerships for Learning, was examined to explore ways in which the traditional mission and roles of school library programs are currently translated online. Results indicated great variation in depth and coverage even among Websites considered exemplary. Sites in the sample are growing more interactive and student-centered, using blogs as supplemental communication strategies. Nevertheless, even these exemplary sites were slow to adopt the advances in technology to meet the learning needs and interests of young adult users. Ideally the study's findings will contribute to understanding of state-of-the-art and will serve to identify trends, as well as serving as a guide to practitioners in planning, developing, and maintaining school library Websites.

Discovering Solutions: How are Journalists Applying Solutions Journalism to Change the Way News is Reported and What Do They Hope to Accomplish?
Solutions journalism, rigorous reporting on responses to social problems, has gained great traction in the last decade. Using positive psychology theory, also known as the theory of well-being, this qualitative study examines the impact of reporting while using solutions journalism techniques. Applying the five pillars of positive psychology theory: positive emotion, engagement, positive relationships, meaning and accomplishment (PERMA), this study used interviews and content analysis to investigate how journalists are applying the tools of solutions journalism as well as what they hope to accomplish in the process. Findings revealed that the application of solutions journalism techniques produces hope and community engagement resulting in flourishing and positive change for individuals, communities and all involved in the reporting process.
Discovering Some Constructive Ways of Promoting Social Cooperation in the First Grade Child
From the first day when the child enters school it should be the teacher's aim to help him "achieve maximum development and at the same time to live harmoniously with others." It is the purpose of this study to provide for the realization of this aim through discovering: 1. In what ways the normal first grade child is lacking in social cooperation and background contributing to this lack; 2. How this lack of social cooperation affects the child's behavior in the daily activities in which he engages at school and suggestions in literature for eliminating social maladjustments; and 3. How the elimination of social maladjustments will help the child to become a happier, better adjusted participant in all of the daily activities in which he engages.

Discovering the Parameters of a Successful Piece: While Developing a Body of Work that Represents My Passion for Clay and My Enthusiasm for Life
Chapter I describes the purpose of the project, which was to develop a body of work that exhibits all that I am at this point in time. The questions I presented to myself were the following: 1. A successful piece is defined by what parameters? 2. What visual qualities indicate my passion for clay and my enthusiasm for life? Chapter II lists and explains the five parameters of a successful piece, which are composition, firing, mark making, color contrast, and movement. Furthermore there is an explanation on how these parameters visually display my passion for clay and my enthusiasm for life. Chapter III is a summary concluding that by discovering my five parameters of a successful piece I now understand the elements that I am searching for in my work. My work will grow from this understanding as long as I have the same passion for clay and enthusiasm for life.

Discovery and Characterization of Two Tn5 Generated pyrA Mutants in Pseudomonas putida and the Generation of Hfr Strains
A pyrA mutation in Pseudomonas putida was isolated using transposon mutagenesis for the first time. Transposon Tn5 was used to inactivate the pyrA gene for carbamoylphosphate synthetase in these mutants. Accordingly, these mutants were defective in pyrimidine and arginine biosynthesis. The suicide vector, pM075, from Pseudomonas aeruginosa, was used to introduce the transposon into the cells. Tn5 was subsequently used to supply homology so that the plasmid pM075 could be introduced in its entirety into the Pseudomonas putida chromosome at the locus of the Tn5 insertion in the pyrA gene. Consequently, these strains exhibited high frequency of recombination and were capable of chromosome mobilization.
Discovery of a Thermophilic Nitrogen Fixing Bacterium
The thermophilic bacterium designated NT-7 was shown to reduce acetylene to ethylene at 35 C. It was found that the organism does not reduce acetylene when it is grown in Burk's medium with 0.3 per cent (w/v) NH4 N0 3 . Reduction of acetylene at 55 C could not be demonstrated due to insolubility of acetylene in Burk's medium at this temperature. It was shown that the bacterium NT-7 can not grow in the absence of atmospheric nitrogen at 55 C when combined nitrogen is not supplied with the nutrient medium. All these characteristics were used to prove that NT-7 is a nitrogen fixing bacterium. Identification procedures confirmed a previous finding that the organisms are rod shaped cells possessing endoepores. Further tests showed that NT-7 is obligately aerobic and motile.
Discovery of Resources and Conflict in the Interstate System, 1816-2001
This study tests a theory detailing the increased likelihood of conflict following an initial resource discovery in the discovering nation and its region. A survey of prior literature shows a multitude of prior research concerning resources and nations' willingness to initiate conflict over those resources, but this prior research lacks any study concerning the effects of the discovery of resources on interstate conflict. The theory discusses the increased likelihood of conflict in the discovering nation as both target and initiator. It further looks at the increased chance of conflict in the discoverer's region due to security dilemmas and proxy wars. The results show strong support for the theory, suggesting nations making new resource discoveries must take extra care to avoid conflict.
A Discrepancy Analysis of Basic Science Teaching Competencies in Secondary Science in Texas
The study has a twofold purpose. The first is to compare the priority order of the seven fundamental areas of skill among the three sample groups, The second is to compare the differences between actual and ideal teacher performance in the seven fundamental skill areas. The conclusions are generalizable only to the population of Texas teacher educators, members of the Texas Science Supervisors Association and members of the Science Teachers Association of Texas, All of the groups had basic agreement as to the priority order of the science teacher competencies being demonstrated by teachers, The profession's success in educating teachers in the content areas is reflected by the priority of the rankings. The position of the science supervisors' ratings of teacher performance between teachers and teacher educators indicated that supervisors have the most accurate view of teacher performance, The least discrepancy among groups occurred in the ideal rating of teacher performance, indicating general agreement as to the level at which teachers should be demonstrating skills, The greatest discrepancy occurred in the identification of actual level of teacher performance.
Discretion, Delegation, and Professionalism: A Study of Outcome Measures in Upward Bound Programs
In our society, American citizens expect public policies to result in programs that address social problems in ways that are both efficient and effective. In order to judge if these two values are being achieved, public programs are often scrutinized through program monitoring and evaluation. Evaluation of public programs often is a responsibility delegated to local-level managers. The resulting discretion has to be balanced with the need for accountability that is also inherent in public programs. Evaluation is often difficult because outcomes are not readily measurable due to the complexity of the problems faced in the public setting. The Upward Bound program provides an example of this. Upward Bound provides services to students from low-income families and those in which neither parent holds a bachelor’s degree in order to increase the rate at which participants complete secondary education and enroll in and graduate from postsecondary institutions. Upward Bound is implemented and evaluated based upon specifications decided upon at the local level. This discretion granted to local level managers has resulted in wide variations in the way the program is being evaluated. This presents a problem for evaluation and has resulted in inconclusive results as to the success of the program. One way to correct this problem is to try and gain a clear understanding of how the evaluation outcome measures are being chosen for Upward Bound. My study accomplished this task.
A Discriminant Analysis of Physically Impaired Worker and Non-Impaired Co-Worker Performance in a Selected Data Processing Environment
The area of performance appraisal of the handicapped individual is a relatively uncharted domain. Previous studies have tended to either lump categories of handicaps together or to concentrate their performance appraisal on simplistic performance criteria. This dissertation focused upon the performance of a group of physically impaired workers and their non-impaired co-workers. Central to this research endeavor was a comparison of the aggregate performances of both groups of workers through the use of parametric factor and discriminant techniques as well as the non-parametric sign test.
Discrimination and Perceived Stress in Sexual and Gender Minorities: Self-esteem As a Moderating Factor
Sexual and gender minorities are subjected to discrimination and stigmatization which increase vulnerability to psychological co-morbidities (Mays & Cochran, 2001). The mechanisms through which discrimination contributes to distress in lesbian, gay, bisexual and transgender (lgbt) communities can be partially elucidated through the minority stress model. The minority stress model argues that minorities are subjected to negative societal attitudes and discrimination that results in excessive psychosocial stress related to their minority position, which is distinct from daily stress. Meyer’s minority stress model is supported by social stress theoriesand data linking discrimination to stress in lgb samples. Researchers suggest that self-esteem buffers the negative effects of adverse experiences but tests of the moderating effect of self-esteem on the discrimination-distress relationship in ethnic and gender minorities yielded mixed results. Szymanski found that self-esteem moderates the relationship between discrimination and psychological distress in a male sexual minority sample, but this has never been tested in a gender-balanced sexual minority sample. We hypothesized that higher levels of self-esteem are associated with lower overall perceived stress in lgbt adults, and that self-esteem acts differentially in lgbt populations to moderate perceived discrimination. We found that discrimination, self-esteem and the interaction effect between discrimination and self-esteem accounted for 53 percent of the total variance in perceived stress scores, ∆R2 = .38; adj. R2 = .53, F(12, 133) = 14.47, p < .001.When we tested whether self-esteem moderated the relationship between discrimination and stress, discrimination was positively related to stress, β = .13, t(144) = 2.14, p < .05, and self-esteem was negatively related to stress, β = -.63, t(144) = -10.26, p < .001. The interaction between self-esteem and discrimination positively correlated with stress, β = .14, t(144) = 2.29, p < .05. Our findings suggest that self-esteem may alleviate the impact of discrimination on perceived stress, which …
Discrimination, Attachment, and Ethnic Identity as Predictors for Wellbeing and American Affirmation among Racial and Ethnic Minority University Students
Extant literature has provided evidence suggesting that ethnic minority individuals experiencing discrimination report poor mental health outcomes, including depression, anxiety, and an overall lower sense of belongingness with the majority culture, but empirical research examining how ethnic identity affects this relationship is extremely scarce. The first goal of the current study was to replicate the results of previous studies demonstrating a strong relationship between discrimination and selected wellbeing indicators: meaning in life, American affirmation, depression, and life satisfaction. The second goal of the study was to examine a moderation model and two moderated moderation models that depict the relationships among adult attachment, the affective component of ethnic identity, exploration and commitment to ethnic identity, and wellbeing indicators. Data was collected from 206 students who were recruited from undergraduate psychology courses. Findings provided partial support to the direct effects of discrimination on various wellbeing indicators but did not support the moderating effect of ethnic identity. Additionally, adult attachment, ethnic identity, and discrimination were not found to significantly interact, but the relationship between discrimination, ethnic identity, and American affirmation was found to be significantly moderated by the affective component of ethnic identity. Discussion on the findings, limitations of the study, future research directions, and counseling implications are addressed.
A Discrimination of Software Implementation Success Criteria
Software implementation projects struggle with the delicate balance of low cost, on-time delivery and quality. The methodologies and processes used to create and maintain a quality software system are expensive to deploy and result in long development cycle-time. However, without their deployment into the software implementation life-cycle, a software system will be undependable, unsuccessful. The purpose of this research is to identify a succinct set of software implementation success criteria and assess the key independent constructs, activities, carried out to ensure a successful implementation project. The research will assess the success of a software implementation project as the dependent construct of interest and use the software process model (methodology) as the independent construct. This field research involved three phases: (1) criteria development, (2) data collection, and (3) testing of hypotheses and discriminant analysis. The first phase resulted in the development of the measurement instruments for the independent and dependent constructs. The measurement instrument for the independent construct was representative of the criteria from highly regarded software implementation process models and methodologies, e.g., ISO9000, Software Engineering Institute's Capability Maturity Model (SEI CMM). The dependent construct was developed from the categories and criteria from the Delone and McLean (1992) MIS List of Success Measures. The data collection and assessment phase employed a field survey research strategy to 80 companies involved in internal software implementation. Both successful and unsuccessful software implementation projects (identified by the Delone/McLean model) participated. Results from 165 projects were collected, 28 unsuccessful and 137 successful. The third phase used ANOVA to test the first 11 hypotheses and employed discriminant analysis for the 12th hypothesis to identify the "best set" of variables, criteria, that discriminate between successful and unsuccessful software implementation projects. Twelve discriminating variables out of 67 were identified and supported as significant discriminators between successful and unsuccessful projects. …
Discrimination of Time-Compressed Speech Stimuli: a Comparison Study Using a Closed-Set Task With Older Adults
Use of time-compressed speech stimuli has been found to be clinically effective in differential diagnosis of lesions of the temporal lobe. However, notably absent from the literature is information concerning performance of adults on time-compressed closed-set speech discrimination tasks. The goal of this study mas to compare performance of 12 males and 12 females between age 50 and age 70 on a time-compressed closed-set speech discrimination test against the performance of 12 males and 12 females between age 10 and age 28 on the same task. The Word Intelligibility by Picture Identification test (WPI) was presented in both non-compressed and time-compressed conditions to all subjects. Previous research suggests that a difference in performance between age groups and between males and females in the older age group should be expected. Average results indicated negligible differences between age or gender groups under any of the conditions tested. Additionally, the test yielded perfect or near perfect scores for all subjects in the non-compressed condition. Lack of differentiation of results suggests that the Word Intelligibility by Picture Identification CUIPI) may be insensitive to the discrimination disorders expected in older adults, that the subjects included in the study were atypical of older adults in general and therefore such discrimination disorders did not exist in the sample, or that the subjects in the study uiere able to apply some type of compensatory strategies which resulted in the unexpected performance.
Discriminative Control of Behavioral Variability in Video Game Play
Creativity can be a useful skill in today's classrooms and workplaces. When individuals talk about creativity, it's unclear what the controlling variables are when we tact behavior as "creative." Research in understanding the processes behind behaviors that are considered "creative" would assist in identifying functional relations and provide insight on how to teach creativity. Since creativity is often described as doing something different from the norm, behavioral variability may be a potential aspect of creativity. This study aimed to replicate previous findings by investigating the effects of discrimination training in a multiple schedule of varied and repetitive responding in the context of a video game. Participants played through a 2D online video game made in Bloxels. Different alternating-colored platforms served as the discriminative stimuli for the vary and repeat components. Three parameters of variability were measured (e.g., left jumps, right jumps, and double jumps). The results of the study indicate that participants were able to learn the discrimination of when to repeat and vary their responses depending on which colored platform they encountered.
Discriminative Stimulus Properties of Cocaine: Tolerance and Cross-Tolerance Characteristics
Rats were trained to discriminate an injection of cocaine, 5.0 mg/kg, from an injection of saline, using a two-lever choice paradigm: one lever was correct after cocaine injection, the other lever was correct after a saline injection. After training, cocaine and methamphetamine were generalized to the cocaine lever, but phenethylamine (PEA) was only partially generalized. Cocaine was injected every 8 hrs, 20.0 mg/kg, and the discriminability of 5.0 mg/kg was tested every other day. Redetermination of the cocaine generalization curve after 6 days of chronic administration showed a shift to the right, from an ED50 of 4.1 mg/kg in the pre-chronic condition to 10.0 mg/kg. Tolerance did not develop to the behavioral effects of cocaine, measured by time to the first reinforcement and response rate. There was cross-tolerance to methamphetamine; however, no evidence for cross-tolerance to PEA was obtained. Following the acquisition of tolerance, chronic administration of cocaine was terminated, and the discriminability of 5.0 mg/kg was tested every other day for loss of tolerance. After 8 days the ED50 returned to 5.0 mg/kg.
Discursive Horizons of Human Identity and Wilderness in Postmodern Environmental Ethics: A Case Study of the Guadalupe Mountains of Texas
Using a genealogy of the narratives of the Guadalupes, I explore three moral identities. The Mescalero Apache exist as caretakers of sacred space. Spanish and Anglo settlers exist as conquerors of a hostile land. The park service exists as captives, imprisoned in the belief that economic justifications can protect the intrinsic value of wilderness. The narrative shift from oral to abstract text-based culture entails a shift from intrinsic to instrumental valuation. I conclude that interpretation of narratives, such as those of the Guadalupes, is not by itself a sufficient condition for change. Interpretation is, however, a necessary condition for expanding the cultural conversation beyond merely instrumental justifications to include caring for wilderness's intrinsic values.
A Discussion of Four Cadenzas Written for the Beethoven Fourth Piano Concerto Opus 58
This paper evaluates the style of four candezas written for the Beethoven Fourth Piano Concerto, Opus 58. Dennis W. Hay introduces the history of the cadenza before focusing on the works by the individual composers: Beethoven, Brahms, Medtner, and Casadesus.
Discussion of "The Ketamine Model of the Near-Death Experience: A Central Rold for the N-Methyl-D-Aspartate Receptor," by Karl L. R. Jansen
Abstract: We review strengths and weaknesses of Karl Jansen's approach to the near-death experience (NDE). Strengths include his limited goals and avoidance of the trap of explaining all features of the NDE with his theory, although he surprisingly misunderstood our previously published position. Additional, we applaud the possible intersection of psychological and biological theories, demonstrated in Jansen's biochemical explanations for the individualized variations in manifestation and adaptive role of the NDE. However, he failed to take into account the pitfalls in the use of analogy, modeling oversimplification, and in taking association as causality and causes as meaningful, in the arguments for his theory.
Disease Tissue Imaging and Single Cell Analysis with Mass Spectrometry
Cells have been found to have an inherent heterogeneity that has led to an increase in the development of single-cell analysis methods to characterize the extent of heterogeneity that can be found in seemingly identical cells. With an understanding of normal cellular variability, the identification of disease induced cellular changes, known as biomarkers, may become more apparent and readily detectable. Biomarker discovery in single-cells is challenging and needs to focus on molecules that are abundant in cells. Lipids are widely abundant in cells and play active roles in cellular signaling, energy metabolism, and are the main component of cellular membranes. The regulation of lipid metabolism is often disrupted or lost during disease progression, especially in cancer, making them ideal candidates as biomarkers. Challenges exist in the analysis of lipids beyond those of single-cell analysis. Lipid extraction solvents must be compatible with the lipid or lipids of interest. Many lipids are isobaric making mass spectrometry analysis difficult without separations. Single-cell extractions using nanomanipulation coupled to mass spectrometry has shown to be an excellent method for lipid analysis of tissues and cell cultures. Extraction solvents are tunable for specific lipid classes, nanomanipulation prevents damage to neighboring cells, and lipid separations are possible through phase dispersion. The most important aspect of single-cell analysis is that it uncovers the extent of cellular heterogeneity that exists among cellular populations that remains undetected during averaged sampling.
The Disestablishment and Disendowment of the Church in Wales
The disestablishment and disendowment of the Church in Wales was a direct result of a renascent Welsh nationalism asserting itself in the daily life of Wales and in the English parliament. This thesis examines the historical, political, and social aspects of the disestablishment and disendowment of the Church.
The Disfigured Muse : Supreme Readers in the Poetry of Wallace Stevens
In "Discourse in the Novel," Mikhail Bakhtin tells us that "Every discourse presupposes a special conception of the listener, of his apperceptive background and the degree of his responsiveness." My study of Wallace Stevens's poetry examines Stevens's "conception of the listener"—in the form of his intratextual readers, their responsiveness, and the shapes that responsiveness takes—and attempts to formulate out of that examination Stevens's theory of reading embodied in his canon of poems.
Dislocation Dynamics Simulations of Plasticity in Cu Thin Films
Strong size effects in plastic deformation of thin films have been experimentally observed, indicating non-traditional deformation mechanisms. These observations require improved understanding of the behavior of dislocation in small size materials, as they are the primary plastic deformation carrier. Dislocation dynamics (DD) is a computational method that is capable of directly simulating the motion and interaction of dislocations in crystalline materials. This provides a convenient approach to study micro plasticity in thin films. While two-dimensional dislocation dynamics simulation in thin film proved that the size effect fits Hall-Petch equation very well, there are issues related to three-dimensional size effects. In this work, three-dimensional dislocation dynamics simulations are used to study model cooper thin film deformation. Grain boundary is modeled as impenetrable obstacle to dislocation motion in this work. Both tension and cyclic loadings are applied and a wide range of size and geometry of thin films are studied. The results not only compare well with experimentally observed size effects on thin film strength, but also provide many details on dislocation processes in thin films, which could greatly help formulate new mechanisms of dislocation-based plasticity.
Dismantling the Psychiatric Ghetto: Evaluating a Blended-Clinic Approach to Supportive Housing in Houston, Texas
Locational decisions based on stigma and low funding have handicapped the efficiency of community based mental healthcare in the United States since 1963. However, the pattern of services in the 21st century American South remains largely unknown. This thesis addresses this gap in knowledge by using a mixed methodology including location allocation, descriptive statistics, and qualitative site visits to explore the geography of community clinics offering both physical and mental health services. The City of Houston has proposed using these facilities to anchor new supportive housing, but introducing more fixed costs to a mismatched system could create more problems than solutions. The findings of this study suggest the presence of an unnecessary concentration of services in the central city and a spatial mismatch between accessible clinics and the poor, sick people in need. Furthermore, this research reveals a new suburban pattern of vulnerability, calling into question long-held assumptions about the vulnerability of the inner city. Building supportive housing around existing community clinics, especially in the central city, may further concentrate vulnerable people thereby contributing to intensifying patterns of service-seeking drift and the continued traumatization of mentally ill homeless persons in Houston.
The Disney Influence on Kindergarten Girls' Body Image
Media is now a part of the early childhood world. In many countries, including industrialized and developing countries, children spend more time consuming various kinds of media. The impact of media on children's perception of their body images has been and continues to be a concern of parents and early childhood professionals. This research examined the influence of Disney movies on Thai kindergarten girls' body images and self-esteem. Thai kindergarten girls completed three measures of body self-image: the Body Figure Preference Scale, the Body Esteem Scale, and the Self-Esteem Scale. The girl participants were randomly assigned to two groups: focused on a female theme (FFT) and focused on a non-human theme (FNT). The experimental group viewed "female" Disney movie themes, while the control group viewed "animal" Disney movie themes. Girls in the experimental group expressed greater body image dissatisfaction scores after watching Disney movies, which was an expected finding. Results from the present study suggest that girls in both groups become concerned about their body esteem after video exposure. However, there was no significant difference in self-esteem between girls in FFT and FNT. In summary, the findings of this study support the belief that Disney movies influence young girls' perceptions of their body image, and they have an awareness of their body size. It can be concluded that Disney movies have an influence on Thai girls' body image dissatisfaction and body esteem. The results also indicated that Thai girls are not totally aware of the influence of Disney media on their self-esteem. Understanding how Disney movies, in particular, and other media, in general, influence young children, especially girls, can encourage parents and educators to identify risk factors associated with children's body image dissatisfaction and low self-esteem.
The Dispersal of Algae and Protozoa by Selected Odonata
This study was designed to show what dissemules may be carried by selected genera of Odonata, where the dissemules may be predominantly carried on the selected insects and to relate the behavior of the selected Odonata to frequency of occurrence of micro-organisms on the insects.
