Technology integration into the classroom is a multi-faceted and complex topic. One factor that can have an effect on a teacher's incorporation of technology into their classroom is pre-service teacher technology training. In this research study the ARCS instructional design model was applied to a pre-service teacher technology course in the hopes of motivating course attendees to both learn about technology incorporation and to incorporate technology into their future classrooms. The ARCS instructional design model that relies on the motivational sub-components of attention, relevance, confidences, and satisfaction to develop instruction that motivates to students to learn course content and goals. This study analyzed a group of pre-service teachers enrolled in a university technology training course to determine if the redesign resulted in the desired outcomes. Pre-test and post-test data was collected using both quantitative and qualitative instruments to analyze the potential effect of the redesigned course.

Research indicates that serious behavior problems begin during the early childhood years. The study examined the perceived preparedness of teachers related to behavior management as well as preschool teachers' usage of evidence-based prevention and intervention strategies. The data indicates that preschool teachers feel prepared for managing aggression in their classrooms and report utilizing evidence-based prevention and intervention strategies regularly. Additionally, the data shows a weak relationship between teacher variables and the likelihood of feeling prepared for managing aggression or utilizing evidence-based strategies. The results can be used to gain a better understanding of special education preschool teachers' training needs in regard to behavior management and managing behavior problems in the preschool classroom.

To date there is no comprehensive understanding of what leadership is, nor is there an agreement among different theorists on what a good or effective leader should be. The purpose of this dissertation is to examine the theoretical and empirical similarities and differences of two styles of leadership – transformational and authentic leadership. Follower outcomes, as well as, the effects of trust and psychological capital within these paradigms are of particular interest. Although theoretical differences are proposed for the leadership style, the extent of overlap suggests the need to more closely examine each theory. Pilot studies were created to validate original scenarios created for the study as well as to examine the validity and reliability of new measurement instruments. The dissertation is designed to determine whether the relationships between authentic leadership and a variety of follower outcomes including performance, affective commitment, satisfaction, trust, and organizational citizenship behavior are similar to those between transformational leadership and these outcomes. In addition, variables more unique to authentic leadership research including psychological capital and follower well-being were examined within both paradigms to determine whether their relationships are similar to each type of leadership style. An experimental study using Qualtrics was used to collect the …

By engaging in collaborative arts-based and arts-informed narrative inquiry with my six-year-old daughter, we explored self-guided materials in art museums in the North Texas area. Though the field of art museum education is becoming increasingly participatory, most academic research related to self-guided materials has fallen short of exploring visitors' experiences with these materials. Furthermore, the perspectives of children have been long overlooked in academic and, at times, institutional research about family experiences in museums. Over the course of nine months, my daughter and I visited art museums and engaged with their self-guided materials, ranging from audio tours to interactive galleries. During this time we created collaborative works of art based on our experiences, which acted as both data collection and analysis in preparation for writing narratives. Our narrative explorations allowed us each to better understand our collective experiences. Though this research specifically targets self-guided materials in art museums, any educator interested in intergenerational or collaborative family learning may find both our methodologies and our conclusions to be helpful in better understanding how narratives are essential to this type of learning.

Social exclusion has garnered much attention from researchers across the social sciences, especially among social psychologists. However, given the fact that social relationships and consumption are two of the central activities in daily life, there is surprisingly little research on the impact of social connection threats within the realm of consumer behavior. This study examines the effect of social exclusion on proenvironmental behavior and green consumption. More precisely, the objectives of this study are threefold. The first objective is to examine whether the findings in social psychology literature on how excluded individuals respond to exclusion when they are exposed to proenvironmental consumption behavior. The second objective of this research is to find the underlying mechanism and to rule out some of the possible explanations (e.g., mood) for this effect. The final objective of this study is to establish some of the boundary conditions (individual differences and situational factors) for the proposed effect. The hypotheses of this study were developed based on two main theoretical bases borrowed from social psychology literature: empathy-altruism hypothesis (Batson 1991) and social reconnection hypothesis (Maner et al. 2007). Overall, it was proposed that while social exclusion decreases individuals’ inclination to engage in proenvironmental activities, socially excluded …

Human behaviors and social norms are transferred to the Internet in complex and divergent ways. The term online disinhibition has been coined to describe situations when Internet users seem to behave more openly and unrestrained online, often acting in ways they would not dare to act in the face-to-face world. According to Suler, there is a need for future research to "focus on which people, under what circumstances, are more predisposed to the various elements of online disinhibition." With this in mind, this descriptive study sought to determine whether or not people are more true to their authentic psychological identities (i.e., genders) during online interaction or create completely new identities because of the more permissive social norms created by cyberspace. Through video recorded face-to-face discussions, reflective online discussions, open-ended online surveys, and semi-structured interviews, qualitative data was collected for analysis. The results and findings demonstrated that some personality traits are magnified during online interaction, but individuals ultimately stay true to their established gender roles.

This study seeks to understand the development of early American ideas of race, religion, and gender as reflected in Indian and Barbary captivity narratives (tales of individuals taken captive by privateers in North Africa) and in plays that take American captives as their subject. Writers of both Indian and Barbary captivity narratives used racial and religious language – references to Indians and North Africans as demonic, physically monstrous, and animal – simultaneously to delineate Native American and North African otherness. The narrative writers reserved particular scorn for the figure of the Renegade – the willful cultural convert who chose to live among the Native Americans or adopt Islam and live among his North African captors. The narratives, too, reflect Early American gendered norms by defining the role of men as heads of household and women’s protectors, and by defining women by their status as dutiful wives and mothers. Furthermore, the narratives carefully treat the figure of the female captive with particular care – resisting implications of captive rape, even while describing graphic scenes of physical torture, and denying the possibility of willful transcultural sexual relationships.

This study presents the integration of light detection and range (LiDAR) and hyperspectral remote sensing to create a three-dimensional bird habitat map in the Greenbelt Corridor of the Elm Fork of the Trinity River. This map permits to examine the relationship between forest stand structure, landscape heterogeneity, and bird community composition. A biannual bird census was conducted at this site during the breeding seasons of 2009 and 2010. Census data combined with the three-dimensional map suggest that local breeding bird abundance, community structure, and spatial distribution patterns are highly influenced by vertical heterogeneity of vegetation surface. For local breeding birds, vertical heterogeneity of canopy surface within stands, connectivity to adjacent forest patches, largest forest patch index, and habitat (vegetation) types proved to be the most influential factors to determine bird community assemblages. Results also highlight the critical role of secondary forests to increase functional connectivity of forest patches. Overall, three-dimensional habitat descriptions derived from integrated LiDAR and hyperspectral data serve as a powerful bird conservation tool that shows how the distribution of bird species relates to forest composition and structure at various scales.

Risk assessments for offenders often combine past records with current clinical findings from observations, interviews, and test data. Conclusions based on these risk assessments are highly consequential, sometimes resulting in increased criminal sentences or prolonged hospitalization. Offenders are therefore motivated to intentionally minimize their risk scores. Intentional minimization is especially likely to occur in offenders with high psychopathic traits because goal-directed deception is reflected in many of the core traits of the disorder, such as manipulativeness, glibness, and superficial charm. However, this connection appears to be based on the conceptual understanding of psychopathy, and it has rarely been examined empirically for either frequency or success. The current study examined the connection between psychopathic traits and the intentional minimization of risk factors using a sentenced jail sample. In general, offenders were able to effectively minimize risk on the HCR-20 and SAQ, while the PICTS, as a measure of cognitive styles, was more resistant to such minimization. Psychopathic traits, especially high interpersonal facet scores, led to greater minimization using a repeated measure, simulation design. Important differences in the willingness and ability to use deception were found based on (a) the content of subscales, and (b) the mode of administration (i.e., interview vs. …

The current study focuses on improving the wear resistance of femoral head component and enhancing the osseo-integration properties of femoral stem component of a hip implant made of a new generation low modulus alloy, Ti-35Nb-7Zr-5Ta or TNZT. Different techniques that were adopted to improve the wear resistance of low-modulus TNZT alloy included; (a) fabrication of graded TNZT-xB (x= 0, 1, 2 wt%) samples using LENS, (b) oxidation, and (c) LASER nitriding of TNZT. TNZT-1B and TNZT-O samples have shown improved wear resistance when tested against UHMWPE ball in SBF medium. A new class of bio-ceramic coatings based on calcium phosphate (CaP), was applied on the TNZT sample surface and was further laser processed with the objective of enhancing their osseo-integration properties. With optimized LASER parameters, TNZT-CaP samples have shown improved corrosion resistance, surface wettability and cellular response when compared to the base TNZT sample.

This study examined the impact that a stress inoculation training (SIT) program had on a small-sized city police department in the southwestern U.S. Specifically, the aim of this study was to investigate how a SIT program impacted police officer self-reported levels of organizational stress, operational stress, perceived life stress, and mood states. All 24 participants were recruited from a population of 132 sworn, active duty police officers and were pre-tested through administration of a questionnaire packet containing a host of measures related to demographics, organizational stressors, operational stressors, general life stressors, and mood states. Participants were then randomly assigned to one of the following treatment conditions: (1) delayed training; (2) SIT program; and (3) SIT plus booster program. On completion of the SIT program, members of each of the treatment conditions were re-assessed through the administration of the aforementioned questionnaire packet. Subsequent to conducting the booster sessions, participants from each treatment condition took part in a second, and final, follow-up assessment. Results suggested that organizational stress was decreased for participants in the SIT program, particularly at follow-up. Results also suggested that energy (i.e., vigor) was increased for participants in the SIT plus booster program at both post-test and follow-up. Furthermore, …

Over the past decade the movement of natural gas drilling operations toward more suburban and urban communities has created unique policy challenges for municipalities. Municipal response is manifest in a variety of institutional arrangements, some more enabling than others regarding citizen access to public hearings. This observation lead to the main research question, “How are variations in citizen participation affecting policy outcomes?” The argument is made that institutions affecting citizen participation, in turn affect policy outcomes. If the general public is given access to public hearings, their preferences for longer setbacks will be taken into account and the approved gas wells will have greater distances from neighboring residences – effectively providing for greater safety. Given the paucity of research on the topic of natural gas drilling, the research first begins with the presentation of a theoretical framework to allow for analysis of the highly complex topic of gas well permitting, emphasizing the rule-ordered relationships between the various levels of decision making and provides a typology of collective action arenas currently used by Texas municipalities. The research uses paired case studies of most similar design and employs a mixed methods process for the collection, analysis and interpretation of the municipal level …

This study uncovers the experiences of Latinos/as in allied health graduate programs and provides vital information which may help increase the number of Latino/a healthcare providers. It focuses on the testimonios (life narratives) of 9 Latinos/as who graduated from allied health graduate programs. Academic resilience and community cultural wealth theories framed the study while testimonio methodology guided data collection. Alumni were interviewed about the personal experiences and educational journeys that led them to successfully complete graduate allied health degrees. Participants’ family background, educational history, personal and environmental factors were considered. Participants described learning about the value of education early in their lives in home and school settings. The interviews also revealed the importance of participants’ personal drive and desire to excel academically and professionally. Participants noted that the academic rigor and adjustment required to succeed in graduate allied health programs, combined with feelings of social isolation, made their transition to the graduate program challenging. Family and social networks were noted as the most supportive in regards to participants’ retention and success. Research implications include the use of methodologies and theoretical frameworks which focus on the voices and experiences of underrepresented students in the allied health professions. Implications for allied health …

This study examines middle school students' perceptions of a future career in a science, math, engineering, or technology (STEM) career field. Gender, grade, predispositions to STEM contents, and learner dispositions are examined for changing perceptions and development in career-related choice behavior. Student perceptions as measured by validated measurement instruments are analyzed pre and post participation in a STEM intervention energy-monitoring program that was offered in several U.S. middle schools during the 2009-2010, 2010-2011 school years. A multiple linear regression (MLR) model, developed by incorporating predictors identified by an examination of the literature and a hypothesis-generating pilot study for prediction of STEM career interest, is introduced. Theories on the career choice development process from authors such as Ginzberg, Eccles, and Lent are examined as the basis for recognition of career concept development among students. Multiple linear regression statistics, correlation analysis, and analyses of means are used to examine student data from two separate program years. Study research questions focus on predictive ability, RSQ, of MLR models by gender/grade, and significance of model predictors in order to determine the most significant predictors of STEM career interest, and changes in students' perceptions pre and post program participation. Analysis revealed increases in the perceptions …

The purpose of this research design is to explore the meaning of death for the female adolescent. A qualitative design was used as the method of research. Twelve participants were selected from a snowball sample ten females and two males. Four participants reported witnessing the death of an individual, five reported a moderated death experience in which they were not present but were told after the fact and three reported no significant experience with death. The study indicated relationships and cause of death as among the pre-conditions towards meaning development for the adolescent female. The two main themes derived from the pre-conditions are an understanding of the inevitability of death for themselves and the experience of death as qualia. Consequences to the experience of death include increased emotional tolerance under stress and a perceived increased maturity suggesting resilience in the adolescent female following a loss. Future areas of research are also addressed.

This qualitative study addressed the question: What are the perceptions of preschool and elementary bilingual and ESL teachers on how technology-enhanced classroom environments support native Spanish-speaking English language learners in the acquisition of English as a second language? With the support of six school districts representing three different regions and 15 schools in Texas, this research investigated technology-enhanced learning environments and the influence of emerging technologies on language acquisition by focusing on classroom interactions and learner engagement in preschool and elementary settings. Forty-six teachers completed the self-identified online questionnaire and from that initial group of participants, 10 were chosen for the face-to-face semi-structured interviews. A two-cycle progressive refinement coding technique was used for the analysis of the teacher interviews. In Vivo coding was selected for the first-cycle coding methodology to study teacher perspectives using their direct language. For the second-cycle methodology, focus coding was chosen as a continuation of the analytical process examining the developing patterns resulting in the initial codes being grouped to form salient categories. This process of reanalyzing and reorganizing coded data led to the creation of four emergent themes and in the views of the teachers interviewed describes how emerging technologies influences English language acquisition. The …
