Academic Progress Scores to Predict Performance on a State Assessment

Description: This quantitative study examined seventh-grade reading scores to determine the extent to which certain demographic variables (race/ethnicity, gender, socioeconomic status) explain and MAP reading scores predict reading scores on the State of Texas Assessment of Academic Readiness (STAAR) in a selected northeast Texas public school. Standardized assessments only compare the relative performance of an individual student to other groups of students using scaled scores, which can vary from year to year and from state to state. With the advent of computer adaptive testing, this study provides information on the predictive validity of benchmark assessments. Specifically, this study looked for predictive evidence that indicates how accurately test data can predict criterion scores. Findings revealed, through a multiple regression analysis, that the fall MAP Rasch Unit (RIT) scores predicted the STAAR scale scores. Using SPSS version 22, the data were entered and analyzed in a multiple regression model to determine the presence of a statistical trend or lack thereof. Demographic data and MAP scores were entered into the regression model to examine the predictive validity of the MAP assessment in determining student performance on the STAAR seventh-grade state-mandated reading assessment. The statistical analysis revealed that MAP RIT scores explain a significant variance related to seventh-grade STAAR reading scale scores. There is a vital need for tools that improve a student's academic development and MAP assessments have been found to predict performance on state-mandated assessments.

Adult Learning: Evaluation of Preferences for Technology and Learning Sources for Workplace Learning

Description: The purpose of this research was to provide an initial investigation of the preferences for both technology and learning sources that are available today in the modern workplace at a large financial institution with a national presence in the USA. In addition to the preferences of the participants, the research includes insights about the culture of the learning organization by using the Dimension of Learning Organization Questionnaire (DLOQ) and two preference surveys. The research methods used in this study are categorized as mixed methods and include both quantitative and qualitative methods. This study is nonpositivist and descriptive. It is based on a triangulation design method which is comprised of analysis from data obtained from the DLOQ and preference surveys, as well as semi-structured interviews with several survey participants. The results of the studies provide the foundational information for an extended quantitative analysis.

Assessing the Older Diabetic Population in the US: A Descriptive Look at This Population from 2001-2010 Focusing upon Education and Clinical Behaviors

Description: The focus of this research study was to gain needed information on the older adult population in the United States who have diabetes. The research method was quantitative retrospective study of American diabetes obtained from the National Health Interview Survey database from 2001 through 2010. The study results confirmed more than one-third of the U.S. diabetics are aged 65 and older. More than 75% of the older diabetic population report clinical limitations or comorbidities. Based on surrogate markers of education, it appears the older diabetic cohort did receive more preventative care visits than did the older nondiabetic population; however, the difference was not robust. I found a slight negative trend between age and emergency room visits in the older diabetic population; in addition, there was a negative association between age and smoking in this population. There continues to be a need for scientific research in this population. Greater numbers need education and more clinical trials specific to the older diabetic should be encouraged.

Associations between Collaborative Learning and Personality/Cognitive Style among Online Community College Students

Description: This research study investigated associations between online community college students' personal characteristics and experiences in online courses (n = 123). Specifically, students' personalities and cognitive styles were examined alongside the perceived quality and outcomes of collaboration. Negative correlations were found between the conscientiousness personality style and both the quality of collaboration (p = .09) and the outcome of collaboration (p = .05). This finding indicates that conscientious students who, according to the literature tend to have higher academic achievement than other students, perceive negative experiences in online collaborative environments. Conversely, a positive correlation was discovered between the extraversion personality type and the perceived outcomes of collaboration (p = .01). Thus, students with a strongly extraverted personality tend to perceive that they benefits from collaborative learning. Approximately 11% of the variance in the collaborative experience was explained by the combined personal characteristics. The reported frequency of collaboration was positively correlated with both the quality (p < .01) and the outcomes of collaboration (p < .01). While not generalizable, these results suggest that not all students perceive benefits from online collaborative learning. It may be worthwhile to teach students traits associated with the extraversion type like flexibility which is important for collaborative learning. Also, teaching students to adopt traits associated with conscientiousness that improve academic achievement like self-regulation may help improve perceptions of collaborative experiences.

British-Style Brass Bands in U.S. Colleges and Universities

Description: Since the 1980s, British-style brass bands - community ensembles modeled after the all-brass and percussion bands of Great Britain - have enjoyed a modest regeneration in the United States. During this same period, as many as 23 colleges and universities in the U.S. have founded their own curricular or extra-curricular brass band. The purpose of this research study was: to discover which schools sponsor a brass band currently; to discover which schools formerly sponsored a brass band but have since discontinued it; to describe the operational practices of collegiate brass bands in the U.S.; and to determine what collegiate brass band conductors perceive to be the challenges and benefits of brass band in the curriculum. Data for the study were collected between February, 2015 and February, 2016 using four custom survey instruments distributed to conductors of college and university brass bands. The results showed that 11 American collegiate institutions were sponsoring a brass band during the period of data collection. Additional findings included descriptions of the operations of collegiate brass bands, such as availability of credit, rehearsal time, and instrumentation. Results also included the conductors' reported perceptions that both challenges and benefits are inherent in student brass band participation, and that brass band is a positive experience for students. An additional 3 community-based brass bands, not sponsored by but located near a college or university, were found to include collegiate students among their player personnel. A total of 9 schools formerly sponsoring brass bands were found to have discontinued their program. A repertoire analysis of 733 titles of compositions performed by both active and formerly active brass bands revealed that bands performed original works for brass band nearly as often as transcribed or arranged works.

Building an Understanding of International Service Learning in Librarianship

Description: From the very beginning, library education has been a mixture of theory and practice. Dewey required apprenticeships to be part of the first library school at the University of Chicago as a method to indoctrinate new professional. Today, acculturation is incorporated into the professional education through a large variety of experiential learning techniques, including internships, practicum, field work, and service learning projects, all of which are designed to develop some level of professional skills within an information organization. But, what is done for understanding library culture? It is said that one cannot truly recognize the extent of one's own cultural assumptions, until they have experienced another. This study followed a group of LIS graduate students that took that next step – going to Russia. By employing a critical hermeneutic methodology, this study sought to understand what value students gain by from working on an assessment project in an international school library. Using a horizon analysis, the researcher established the worldview of participants prior to their departure, analyzed their experience through post-experience interviews, and constructed an understanding of value. Among other concepts, the researcher looked specifically to see whether "library cultural competency", understanding library culture in global context, was developed through working on a service learning project within an international school library. This dissertation provides feedback for the program leaders and ideas for future research.

Cardiovascular Fetal Programming in Quail (Colinus virginianus), An Avian Comparative Model

Description: The consequences of early embryonic insults and how they affect subsequent life reflects the emerging concept of "fetal programming". The aim of this project is to study the effects of embryonic insults as they subsequently manifest themselves in adults, with emphasis on the heart and vasculature. My experiments establish that fetal programming operates on the bobwhite quail inducing similar changes as those observed in mammalians and other birds. The quail's fast development provides reliable data in a short period of time than other avian models (e.g. domestic chicken). Data on quail showed a correlation between egg mass and hatchling mass; where small eggs produce small hatchlings but a high mortality made it impractical as a stressor for this study. Hypoxia was used as a stressor during embryonic incubation, where it induced a low hatching weight in quail that was not observable in adult birds. Morphological measurements demonstrated an increased ventricular collagen content and reduced ventricular lumen in birds in adults incubated in hypoxia consistent with hypertension. The hematological analyzes showed few differences indicating organ remodeling instead of hematopoietic compensation. The assessment of vascular reactivity pointed out an impaired endothelium dependent relaxation commonly associated to hypertension in birds and mammals. Fetal programming could be a widespread response to an adverse prenatal environment in endotherms and the resulting data from this work contributes to our understanding of fetal programming in vertebrates and its long term consequences.

Chemical and Electronic Structure of Aromatic/Carborane Composite Films by PECVD for Neutron Detection

Description: Boron carbide-aromatic composites, formed by plasma-enhanced co-deposition of carboranes and aromatic precursors, present enhanced electron-hole separation as neutron detector. This is achieved by aromatic coordination to the carborane icosahedra and results in improved neutron detection efficiency. Photoemission (XPS) and FTIR suggest that chemical bonding between B atoms in icosahedra and aromatic contents with preservation of π system during plasma process. XPS, UPS, density functional theory (DFT) calculations, and variable angle spectroscopic ellipsometery (VASE) demonstrate that for orthocarborane/pyridine and orthocarborane/aniline films, states near the valence band maximum are aromatic in character, while states near the conduction band minimum include those of either carborane or aromatic character. Thus, excitation across the band gap results in electrons and holes on carboranes and aromatics, respectively. Further such aromatic-carborane interaction dramatically shrinks the indirect band gap from 3 eV (PECVD orthocarborane) to ~ 1.6 eV (PECVD orthocarborane/pyridine) to ~1.0 eV (PECVD orthocarborane/aniline), with little variation in such properties with aromatic/orthocarborane stoichiometry. The narrowed band gap indicate the potential for greatly enhanced charge generation relative to PECVD orthocarborane films, as confirmed by zero-bias neutron voltaic studies. The results indicate that the enhanced electron-hole separation and band gap narrowing observed for aromatic/orthocarborane films relative to PECVD orthocarborane, has significant potential for a range of applications, including neutron detection, photovoltaics, and photocatalysis.

Clinical Symptoms and Signs Related to Voice Disorders among Collegiate-Level Singers: A Retrospective Study

Description: The objectives of this research were to (1) characterize the demographics and vocal health history of collegiate-level singers, particularly those with a voice disorder and (2) describe and compare self-reported symptoms of singers across diagnostic categories of vocal fold disorders. Clinical reports of 56 collegiate-level singers (15 male and 41 female) who visited the Voice Diagnostic Clinic at the University of North Texas for voice evaluations between 2010 and 2015 were reviewed. Information was extracted from clinical records including demographic data, vocal health history, self-reported voice-related symptoms, and voice diagnosis confirmed by strobolaryngoscopic examinations and phonatory function testing. Diagnoses of voice disorders were grouped under three categories: normal (i.e., no perceptible pathology), benign lesions and irritation/inflammation. Seven singers were diagnosed as normal, 27 (51.8%) with benign lesions, and 22 (39.3%) with irritation/inflammation. All singers diagnosed as normal were females. Female singers have twice as many benign lesions as irritation/inflammation whereas males presented the opposite pattern. Nodules, polyps, cysts and irritation/inflammation were the most common voice disorders. Singers with allergies and a past history of voice problems demonstrated a higher incidence of voice disorders. The top five self-reported vocal symptoms were worse voice in the morning (50%), pain in throat (46.4%), voice worse with prolonged use (44.6%), vocal fatigue (42.9%), and breathiness (41.1%). Self-reported symptoms are not a reliable screening tool to determine presence or absence of vocal pathology. Voice teachers must be familiar with the singing and speaking voice of each student, so as to perceive early onset of vocal attrition symptoms and encourage the student in seeking medical attention.

Costly Ignorance: The Denial of Relevance by Job Seekers: A Case Study in Saudi Arabia

Description: Job centers aid businesses seeking qualified employees and assist job seekers to select and contact employment and training services. Job seekers are also offered the opportunity to assess their skills, abilities, qualifications, and readiness. Furthermore, job centers ensure that job seekers are complying with requirements that they must meet to benefit from job assistance programs such as unemployment insurance. Yet, claimants often procrastinate and/or suspend their job search efforts even though such actions can make them lose their free time and entitlements, and more importantly they may lose the opportunity to take advantage of free information, services, training, and financial assistance for getting a job to which they have already made a claim. The current work looks to Chatman's "small worlds" work, Johnson's comprehensive model of information seeking, and Wilson's "costly ignorance" construct for contributions to understanding such behavior. Identification of a particular trait or set of traits of job seekers during periods of unemployment will inform a new Job Seeking Activities Model (JSAM). This study purposely examines job seeker information behavior and the factors which influence job seekers' behavior, in particular, family tangible support as a social norm effect. A mixed method, using questionnaires for job hunting completers and non-completers and interviews for experts, was employed for data collection. Quantitative data analysis was conducted to provide the Cronbach α coefficient, Pearson's product moment correlation, an independent-sample t-test, effect size, and binary Logit regression. The qualitative data generated from the interview transcript for each section of the themes and subthemes were color coded. Finally, simultaneous triangulation was carried out to confirm or contradict the results from each method. The findings show that social norms, particularly uncontrolled social support provided by their families, are more likely to make job seekers ignore the relevant information about jobs available to them in favor ...

A Decomposition of the Group Algebra of a Hyperoctahedral Group

Description: The descent algebra of a Coxeter group is a subalgebra of the group algebra with interesting representation theoretic properties. For instance, the natural map from the descent algebra of the symmetric group to the character ring is a surjective algebra homomorphism, so the descent algebra implicitly encodes information about the representations of the symmetric group. However, this property does not hold for other Coxeter groups. Moreover, a complete set of primitive idempotents in the descent algebra of the symmetric group leads to a decomposition of the group algebra as a direct sum of induced linear characters of centralizers of conjugacy class representatives. In this dissertation, I consider the hyperoctahedral group. When the descent algebra of a hyperoctahedral group is replaced with a generalization called the Mantaci-Reutenauer algebra, the natural map to the character ring is surjective. In 2008, Bonnafé asked whether a complete set of idempotents in the Mantaci-Reutenauer algebra could lead to a decomposition of the group algebra of the hyperoctahedral group as a direct sum of induced linear characters of centralizers. In this dissertation, I will answer this question positively and go through the construction of the idempotents, conjugacy class representatives, and linear characters required to do so.

Defect Behaviors in Zinc Oxide and Zinc Titanates Ceramics from First Principles Computer Simulations

Description: ZnO and ZnO-TiO2 ceramics have intriguing electronic and mechanical properties and find applications in many fields. Many of these properties and applications rely on the understanding of defects and defect processes in these oxides as these defects control the electronic, catalytic and mechanical behaviors. The goal of this dissertation is to systematically study the defects and defects behaviors in Wurtzite ZnO and Ilmenite ZnTiO3 by using first principles calculations and classical simulations employing empirical potentials. Firstly, the behavior of intrinsic and extrinsic point defects in ZnO and ZnTiO3 ceramics were investigated. Secondly, the effect of different surface absorbents and surface defects on the workfunction of ZnO were studied using DFT calculations. The results show that increasing the surface coverage of hydrocarbons decreased the workfunction. Lastly, the stacking fault behaviors on ilmenite ZnTiO3 were investigated by calculating the Generalized Stacking Fault (GSF) energies using density functional theory based first principles calculations and classical calculations employing effective partial charge inter-atomic potentials. The gamma-surfaces of two low energy surfaces, (110) and (104), of ZnTiO3 were fully mapped and, together with other analysis such as ideal shear stress calculations.

Determinants of Women's Autonomy in Nepal

Description: Nepal in recent times has witnessed a proliferation of community-based organization (CBOs). Established by local residents, CBOs are small level organizations that promote and defend the rights and interests of people especially that of minorities and the disadvantaged. One such minority group that CBOs greatly focus on are women. Despite dramatic increase in the number of CBOs in Nepal its impact on women is understudied. The purpose of this dissertation is to analyze the relationship between Nepalese women's participation in CBOs and their autonomy. Autonomy comprises of four different dimensions; physical mobility, financial autonomy, household decision-making, and reproductive autonomy. Modifying the conceptual framework used by Mahmud, Shah, and Becker in 2012, I hypothesize that women who participate in CBOs experience greater autonomy. Data from the 2008 Chitwan Valley Family Study is used for analysis. Using SPSS, separate logistic regressions are run to analyze the relationship between CBO membership and the dimensions of autonomy. The results support three of the four proposed major hypotheses. Nepalese women who participate in CBOs have greater autonomy in terms of physical mobility, financial autonomy, and household decision-making. No evidence was found to establish link between CBO membership and reproductive autonomy. The variables that are controlled for in the study include age, caste, religion, education, marital status, exposure to television, exposure to radio, and relationship with one's mother-in-law.

District Leadership Supporting PLC Implementation in a Rapid Growth District

Description: A growing body of work has emerged regarding the responsibilities required of district leaders in establishing plans that initiate and create conditions for sustainability of continuous improvement achieved through a systemic reform structure such as professional learning communities. However, limited research exists in respect to sustaining cultures of continuous improvement in rapid growth districts. Rapid growth districts can be described as school systems, which construct and open multiple campuses annually. The underlying premise of this study considered how humans interact with one another within a rapidly changing professional organization. Change theory, professional capital, organizational learning theory, and system reform emerge as the conceptual framework in this study of district support of professional learning communities. Data collection for this qualitative descriptive case study included interviewing six K-12 principals, administering the PLCA-DS survey to 247 K-12 staff members, and document review. Recognition of the importance of the PLC framework, building capacity, development of collaborative culture, and issues resulting from constant change due to rapid growth were the four themes generated by the participants to support continuous improvement in a rapid growth district. The four themes combined with the components of the conceptual framework outline how district leaders in a rapidly changing environment cultivate a process leading to system-wide improvement.

Drought: Construction of a Social Problem

Description: Drought is a complex subject that has varied definitions and perspectives. Although drought has historically been characterized as an environmental problem from both the meteorological and agricultural communities, it is not considered a sociological disaster despite its severe societal impacts. Utilizing the framework developed by Spector and Kitsuse (2011) and Stallings (1995), this research examines the process through which drought is defined as a social problem. An analysis of the data revealed drought was well covered in Africa, India, China, Australia, and New Zealand, yet very little coverage focused on the United States. There were less than 10 articles discussing drought and drought impacts in the United States. The workshops/meetings examined also were lacking in the attention to drought, although their overall theme was focused on hazards and resilience. Six sessions in over 16 years of meetings/workshops focused on the topic of drought, and one session was focused on the condition in Canada. The interviews uncovered five thematic areas demonstrating drought understanding and awareness: Use of outreach to get the message out; agricultures familiarity with drought; the role of drought in media; the variability of what drought is; and water conservation. Drought's claims-makers who are dedicated to providing outreach and education to impacted communities. Drought is often overlooked due to its slow onset and evolving development makes it difficult to determine when to engage in recovery efforts. Drought defined as a social problem also expands theoretical conversations regarding what events or issues should be included within the sociological disaster list of topics.

The Effects of Student-Perceived Instructor Demotivating Behaviors on Doctoral Students' Information Seeking Behaviors

Description: In their studies on student motivation in th4e 1990s, Gorham & Christophel and Christophel & Gorham found that students perceived their own demotivation to be caused by instructor behaviors. While there are studies that explore the topic of student demotivation and other studies that illustrate the great influence instructors have on student information seeking behaviors, research focusing on the connection between these two concepts is almost nonexistent. Using Gorham & Christophel's concept of instructor-owned student demotivation, this mixed-methods study sought to identify which instructor behaviors doctoral computer science and information science students found demotivating and to what extent their perceptions of these demotivating instructor behaviors influenced their information seeking behaviors in a face-to-face classroom. Demographic and student-perceived demotivating instructor behavior surveys along with semi-structured interviews and follow-up questions were used to collect data. The surveys will be analyzed using descriptive statistics in Excel, and the semi-structured interviews and follow up questions were analyzed using content analysis and Colaizzi's method of phenomenological enquiry in NVivo. The findings showed that instructor demotivating behaviors not only influence student information seeking behaviors in the classroom, but they also can lead to lasting effects on the student. In addition, the participants have expectations of instructor behaviors, which come from their own experiences. These expectations also influence the level of demotivation they feel in a face-to-face classroom.

Evolving Curricular Models in Culinary Arts: An Instrumental Case Study of a Technical Field

Description: The purpose of this research study was to examine how chefs and other individuals in the food industry understood the field of culinary arts. This study used an instrumental case study with purposeful sampling of multiple cases. Through a series of open-ended interviews using snowball-sampling strategy that concluded with 45 participants sharing their experiences in culinary education and employment, several themes emerged across all of the interviews: (1) Disempowerment of those who have been successful in the culinary arts; (2) Conflict in the field; and, (3) Needs of employers not being met. Following the analysis of the data, two research questions were inductively formed: (1) How do the participants' understandings vary based upon the three models (apprenticeship, associate degree, and baccalaureate degree) of culinary education? (2) How do these themes vary depending upon the three models of culinary education? What resulted was thick description of the impact of the three models of formal chef education has had on the field of culinary arts, followed by the potential in the development of the baccalaureate degree model as it represented an opportunity for field redefinition in culinary arts. This study produced a set of data revealing that current culinary education has become one that has bred disempowerment, continued conflict in the field of culinary arts, and left needs unfullfilled related to technical skills required for successful employment. The shift from the time-consuming and expensive model of apprenticeship to the development of the associate degree has necessitated a reconsideration of culinary education. What has been offered in this research is the potential for a transformation facilitated within a baccalaureate degree that could intertwine both technical skills and academic knowledge.

Framework to Evaluate Entropy Based Data Fusion Methods in Supply Chain Management

Description: This dissertation explores data fusion methodology to deduce an overall inference from the data gathered from multiple heterogeneous sources. Typically, if there existed a data source in which the data were reliable and unbiased, then data fusion would not be necessary. Data fusion methodology combines data form multiple diverse sources so that the desired information - such as the population mean - is improved despite redundancies, inaccuracies, biases, and inflated variability in the data. Examples of data fusion include estimating average demand from similar sources, and integrating fatality counts from different media sources after a catastrophe. The approach in this study combines "inputs" from distinct sources so that the information is "fused." Another way of describing this process is "data integration." Important assumptions are 1. Several sources provide "inputs" for information used to estimate parameters of a probability distribution. 2. Since distributions for the data from the sources are heterogeneous, some sources are less reliable. 3. Distortions, bias, censorship, and systematic errors may be more prominent in data from certain sources. 4. The sample size of sources data, number of "inputs," may be very small. Examples of information from multiple sources are abundant: traffic information from sensors at intersections, multiple economic indicators from various sources, demand data for product using similar retail stores as sources, polling data from various sources, and disaster count of fatalities from different media sources after a catastrophic event. This dissertation seeks to address a gap in the operations literature by addressing three research questions regarding entropy base data fusion (EBDF) approaches to estimation. Three separate, but unifying, essays address the research questions for this dissertation. Essay 1 provides an overview of supporting literature for the research questions. A numerical analysis of airline maximum wait time data illustrates the underlying issues involved in EBDF methods. This ...

A History of Overcoming: Nietzsche on the Moral Antecedents and Successors of Modern Liberalism

Description: This work aims to understand human moral psychology under modern liberalism by analyzing the mature work of philosopher Friedrich Nietzsche. I seek to understand and evaluate Nietzsche's claim that liberalism, rather than being an overturning of slave morality, is an extension of the slave morality present in both Judaism and Christianity. To ground Nietzsche's critique of liberalism theoretically, I begin by analyzing his "master" and "slave" concepts. With these concepts clarified, I then apply them to Nietzsche's history by following his path from Judaism to liberalism and beyond--to his "last man" and Übermensch. I find that Nietzsche views history as a series of overcomings wherein a given mode of power maintenance runs counter to the means by which power was initially attained. Liberalism, as the precursor and herald of the "last man," threatens the end of overcoming and therefore compromises the future of human valuation and meaning.

Human-Animal Relational Theory: A Constructivist-Grounded Theory Investigation

Description: Constructs of human-animal relational theory (HART) were investigated to determine how those constructs manifested in animal-assisted therapy in counseling (AAT-C) from the perspectives of 6 participants (2 counselors, females, ages 28 and 32, both non-Hispanic and White; 2 clients, male and female, ages 55 and 23, respectively, both non-Hispanic and White; and, 2 therapy animals, canines, Labrador retriever and spaniel mix, ages 4 and 5, respectively). Using constructivist-grounded theory, a research team analyzed qualitative data from observations, interviews, and field notes. From the iterative process of multiphasic coding and constant comparison, these findings emerged: (a) consistency between Chandler's (in press) constructs and participants' experiences of AAT-C, (b) more meaningful therapeutic impacts for clients from client-initiated human-animal relational processes (HARPs) than counselor-initiated HARPs, (c) development of rich definitions and descriptions of Chandler's constructs, and (d) descriptions of interactive experiences of AAT-C and client resistance in the context of HART. Clinicians and educators in the field of AAT can apply the processes, practices, and principles from this study in their work to enhance positive therapeutic impacts for clients. As Chandler's constructs were supported in this study, AAT authors and researchers can solve a glaring problem of inconsistent terminology in the AAT literature by using those constructs in future studies and publications as operationalized nomenclature for standardized AAT interventions.

The Impact of Psychotherapeutic Reiki on Anxiety and Mindfulness: A Single-Case Design

Description: Reiki healing is one of several complementary and integrative therapies becoming increasingly prevalent in mental health counseling. It has been identified in the medical field for its usefulness in treating anxiety, depression, distress, and pain but has rarely been studied for its counseling impact on client wellness. I conducted single-case research to explore psychotherapeutic Reiki's (PR's) influence on adult clients' anxiety symptoms and perceived sense of mindfulness and provided analysis of data collected from two assessments administered weekly: the Adult Manifest Anxiety Scale-Adult and the Mindful Attention Awareness Scale. Three of the four participants demonstrated significant improvement in both anxiety and mindfulness over the course of the PR intervention. The study revealed potential therapeutic benefits for integrating PR with conventional talk therapy. Included in discussion of study results are clinical implications and importance, suggestions for future research, and limitations.
