Development of a Test Blueprint for a Hospitality Management Capstone Course to Measure Programmatic Student Learning Outcomes
The purpose of this study was to develop a test blue-print for a hospitality management capstone course to measure programmatic student learning outcomes. A total of 50 hospitality industry professionals and hospitality management faculty were interviewed through focus group discussions, and a post-focus group survey was conducted to determine a weighted percentage for each of the nine determined content domains. A test blueprint was developed from the weighted proportions determined by this study and a process by which other educational institutions could follow to establish a consistent and accurate evaluation method for a capstone course was described.

The Development of the Child Interpersonal Relationships and Attitudes Assessment for Child Centered Play Therapy
The purpose of this study was to develop a parent report form instrument congruent with the philosophy of child-centered play therapy. The study sought to develop an instrument with acceptable levels of construct validity, reliability, sensitivity to clinical attitudes and relationships, and responsiveness to intervention. The Child Interpersonal Relationships and Attitudes Assessment (CIRAA) and the Child Behavior Checklist (CBC) and the Parenting Stress Index (PSI) were administered to 136 parents of children aged 3 to 10. The children of the parents sample consisted of 90 males and 46 females. Exploratory factor analysis was conducted for construct validity. Parallel analysis was conducted to determine the number of factors to retain. The factor solution explained 53.86% of the variance, which is an acceptable amount of the variance. Cronbach's alpha was conducted for total scale and all subscales. Reliability scores for the total score and subscales were acceptable, with an overall reliability coefficient of .93. A Pearson's r was conducted for concurrent validity between the instrument, the CBC, and the PSI, with Pearsons' r of .75 and .74 respectively. Paired-sample t-tests using the pretest and posttest scores of the instrument in development examined the responsiveness of the instrument to play therapy intervention at …

Device Engineering for Enhanced Efficiency from Platinum(II) Phosphorescent OLEDs
Phosphorescent organic light emitting diodes (PHOLEDs) based on efficient electrophosphorescent dopant, platinum(II)-pyridyltriazolate complex, bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II) (Pt(ptp)2) have been studied and improved with respect to power efficiency, external efficiency, chromacity and efficiency roll-off. By studying the electrical and optical behavior of the doped devices and functionality of the various constituent layers, devices with a maximum EQE of 20.8±0.2 % and power efficiency of 45.1±0.9 lm/W (77lm/W with luminaries) have been engineered. This improvement compares to devices whose emission initially could only be detected by a photomultiplier tube in a darkened environment. These devices consisted of a 65 % bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II) (Pt(ptp)2) doped into 4,4'-bis(carbazol-9-yl)triphenylamine (CBP) an EML layer, a hole transporting layer/electron blocker of 1,1-bis[(di-4-tolylamino)phenyl]cyclohexane (TAPC), an electron transport layer of 1,3,5-tris(phenyl-2-benzimidazolyl)-benzene (TPBI), and a LiF/Al cathode. These devices show the acceptable range for warm white light quadrants and qualify to be called "warm white" even w/o adding another emissive layer. Dual EML devices composed of neat Pt(ptp)2 films emitting orange and CBP: Pt(ptp)2 film emitting blue-green produced a color rendering index (CRI) of 59 and color coordinates (CIE) of (0.47,0.49) at 1000Cd/m² with power efficiency of 12.6±0.2 lm/W and EQE of 10.8±0.2 %. Devices with two blue fluorescent emission layers as singlet …

The Dichotomy of Congressional Approval
This thesis seeks to understand how political awareness affects what information one uses to indicate their approval or disapproval of Congress and its members. More concisely, do more and less aware individuals rely on the same pieces of political information to mold their opinions of Congress? The second question of concern is what role does media consumption play in informing survey respondents about Congress. Third, I consider how survey respondents use cues like the condition of the economy and presidential job performance to help formulate their opinion of Congress Finally, by applying the Congressional approval literature to incumbent level approval, I seek to advance the theory and literature on what motivates the approval of incumbents.

Differences Among Abused and Nonabused Younger and Older Adults as Measured by the Hand Test
The purpose of this study was to explore the effects of participants' abused or nonabused status as it interacted with their age and gender in producing different patterns of Hand Test responses as a function of the age or gender of the card. Participants, 61 young adults (M age = 23) and 60 older adults (M age = 73), were presented with the original Hand Test cards, as well as four alternate versions (e.g., young male, young female, older male, and older female). Expected effects varying by age, gender, and abuse status were not found. Results indicated main effects for participant abuse status, which were largely consistent with previous Hand Test research. Significant interaction effects were also found for participant age by participant abuse status (p < .05), as well as participant age by participant gender by participant abuse status (p < .05). An interaction effect was also found for Hand Test version by participant abuse status (p < .05), Hand Test version by participant age by participant abuse status (p < .05), as well as Hand Test version by participant gender by participant abuse status (p < .05). These results suggest that the alternate forms of the cards may …

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.

DNA Degradation as an Indicator of Post-Mortem Interval
The question of post-mortem interval (PMI) or time since death is often the most sought after piece of information associated with a medical death investigation. Based on the observation that DNA degradation disproportionately affects the analysis of larger genetic loci, it was proposed that DNA degradation, as a result of autolysis or putrefaction, could prove suitable as a potential rate-of-change indicator of PMI. Nine randomly amplified polymorphic DNA (RAPD) analysis primers and three sets of directed amplification primers were evaluated to determine their suitability for use in assessing the degree of DNA fragmentation in tissue samples. They were assessed for amplicon specificity, total DNA target sensitivity, allele monomorphism and the observance of degradation-based profile changes. Markers meeting the requisite criteria were then used to assess a range samples degraded under controlled and uncontrolled conditions. Tissue samples collected from seven domestic pigs (Sus scrofa) were incubated under controlled laboratory or uncontrolled field conditions to produce samples simulating those potentially collected in a forensic case. DNA samples isolated from these specimens were then analyzed at those loci which had been determined to meet the requisite criteria. Collectively, data generated from these analyses indicate that genetic profiles generated by this approach can provide …

Do College Students with ADHD have Expressive Writing Difficulties as Do Children with ADHD?
This study analyzed the expressive writing of college students. Twenty-two ADHD students and 22 controls were asked to write a story based on a picture story and a personal challenge. The texts were compared based on several qualitative and quantitative parameters. The results show that students in both groups presented similar text quality. Out of six qualitative parameters only one was statistically different between the two groups: ADHD students performed worse in adequacy, but only in the picture task. Students writings were also investigated using corpus based analysis. This analysis showed that ADHD students used less unusually frequent words in the picture story but more in the challenge task. Taken together the findings indicate no significant difference in expressive writing between ADHD and non ADHD college students. An explanation to this result is that college students with ADHD may have passed the filter of prior education.

Does the Provision of an Intensive and Highly Focused Indirect Corrective Feedback Lead to Accuracy?
This thesis imparts the outcomes of a seven-week long quasi-experimental study that explored whether or not L2 learners who received intensive and highly focused indirect feedback on one type of treatable error - either the third person singular -s, plural endings -s, or definite article the - eventually become more accurate in the post-test as compared to a control group that did not. The paired-samples t-test comparing the pre-test and post-test scores of both groups demonstrates that the experimental group did no better than the control group after they received indirect corrective feedback. The independent samples t-test measuring the experimental and control group's accuracy shows no significant difference between the two groups. Effect sizes calculated, however, do indicate that, had the sample sizes been bigger, both groups would have eventually become more accurate in the errors targeted, although this would not have been because of the indirect feedback.

Domestic Violence Shelters in Texas: Responding to Programming Needs of Older Victims of Intimate Partner Violence
This study examined if domestic violence shelters in Texas are responding to the needs of older female victims of intimate partner violence. Data for this study was collected through online questionnaire surveys of 45% of Texas domestic violence shelters. Findings of this study indicated that less than 10% of Texas shelters are providing specialized programming for older victims of IPV. In Texas, the demographic growth of older adults has remained comparable to increased national trends. The state of Texas will face several policy implications and social issues related to an older population that is rapidly growing. This includes, the importance of addressing certain members of an aging population who continue to fall victim to domestic violence. Furthermore, an unchanged resource of safety for victims of IPV is domestic violence shelters. Therefore, this study challenges current domestic violence shelter policies to address this issue of a rapidly growing segment of the Texas population. This study found less than 10% of shelters in Texas, who participated in this study, were providing specialized programming and outreach for older victims. Important practical implications for domestic violence shelter programming in Texas is provided.

"The Dying Mother:" Historical Citations of Mary Goffe's Seventeenth-Century Near-Death Apparition
Abstract: Traditionally, certain cases have been of particular importance to students of near-death phenomena. Such cases are more than mere examples or research data; they are resources that are generally used to defend particular theoretical ideas, such as the projection of the spirit or of some subtle body from the physical body around the time of death. One such case was that of Mary Goffe, a seventeenth-century apparition of a dying woman that Richard Baxter reported in his book "The Certainty of the Worlds of Spirits" (1691). This paper includes a reprint of the original case report and a discussion of how later writers used the case to defend the idea that something may leave the body during near-death states.

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress
This study reports and evaluates child outcome measures at a non-profit autism treatment program providing applied behavior analysis (ABA) based services to children age 3 to 8. To accomplish this, a review was conducted of available outcome data for a 1 year period. Several categories of outcome measures have been reported in the autism treatment literature (post-intervention educational placement, cognitive status, developmental and achievement status and/or progress, autism symptom reduction, and diagnostic reclassification). This study found that the program relied on 2 sources of data to evaluate child outcome: Hawaii Early Learning Profile® and program goal mastery. Children are making progress as indicated by these measures. The findings are discussed in relation to broader outcome recommendations.

Eating from the Tree of Knowledge: The Impact of Visual Culture on the Perception and Construction of Ethnic, Sexual, and Gender Identity
This study explores the way that visual culture and identity creates understanding about how the women in my family interact and teach each other. In the study issues of identity, liminality, border culture, are explored. The study examines how underrepresented groups, such as those represented by Latinas, can enter into and add to the discourses of art education because the women who participated have learned to maneuver through the world, passing what they have learned to one another, from one generation to the next. Furthermore, the study investigates ways in which visual cues offer a way for the women in my family to negotiate their identity. In the study the women see themselves in signs, magazines, television, dolls, clothing patterns, advertisements, and use these to find ways in which to negotiate the borderlands of the places in which they live. Although the education that occurred was informal, its importance is in creating a portal through which to self reflect on the cultural work of educating.

Ecological Sustainability and Peace: The Effect of Ecological Sustainability on Interstate and Intrastate Environmental Conflict
This study examines the relationship between ecological sustainability and violent conflict at both the interstate and intrastate level. In particular, this study explores the effect of ecological sustainability of a society on the initiation and the occurrence of violent conflict. By developing a theory, which is named "Eco-peace," this study hypothesizes that the more ecologically sustainable the socioeconomic system of societies, the less likely the society is to initiate interstate conflict. Regarding intrastate conflict, it is hypothesized that the more ecologically sustainable the mode of development pursued by the Third World society is, the more likely that society is to experience intrastate conflicts. To test the hypotheses, this study conducts cross-national time-series analyses for 97-127 countries. Negative binomial and Poisson models are used for interstate conflict during 1960-2001, and logit and rare event logit models are used for intrastate conflict during 1960-1999. Militarized interstate dispute dataset and Uppsala Armed Conflict Program dataset are employed for interstate and intrastate conflict. For ecological sustainability, Ecological sustainability factor index and Environmental sustainability index are used. Through the analyses, this study found the supports for the theoretical argument that the ecologically unsustainable modes of development cause the initiation of interstate conflict and the incidence …
