Adolescent goals and their reports of what they do to achieve those Goals
Twenty-five adolescents' ranking of a set of equally highly valued goals on a Paired-comparisons Survey was compared with what adolescents say they are doing to achieve those goals. Results of the Paired-comparisons Survey showed that adolescents ranked career, interpersonal, and educational goals rather high and reputation and self-presentation goals rather low. Results analyzed with a contingency coefficient and biserial correlation indicated that not all number one ranked goals had the same value for a particular adolescent, and that number one ranked goals were correlated with verbal reports of concrete actions directed at achieving those goals.
Adolescent Insomnia as a Predictor of Early Adulthood Outcomes
Access: Use of this item is restricted to the UNT Community.
Recent research found insomnia is a risk factor for psychiatric disorders in adults. To see if the same would be true in adolescents, the current study re-analyzed data from a national longitudinal study collected by ADDHealth that evaluated health behaviors in 4552 adolescents (mean age 14.9 years [SD 1.7]) at baseline and again 7-8 years later (n = 3489) during young adulthood. Insomnia was reported by 9.2% of the adolescents. Cross-sectionally, adolescent insomnia was associated with alcohol, cannabis, non-cannabis drugs, and tobacco use, and depression after controlling for gender and ethnicity. Prospectively, adolescent insomnia was a significant risk factor for depression diagnosis, suicidal ideation, and the use of depression and stress prescription medications in young adulthood after controlling for gender, ethnicity, and significant baseline variable. In addition, a trend was noted for suicidal attempts.
Adolescent Psychopathy in an Adjudicated Male Population: The Role of Sensation Seeking, Impulsivity, and Externalizing Disorders
Psychopathy, as conceptualized by Cleckley (1941), describes a constellation of psychological and behavioral correlates including superficial charm, untruthfulness, lack of remorse or shame, poor judgment, and failure to learn from experience. Based on Cleckley's initial work, Hare (1991) developed a two-factor model of psychopathy. The purpose of this study was to investigate the roles that sensation seeking, impulsivity, ADHD, conduct disorder, and oppositional defiant disorder have on adolescents classified as psychopaths. The participants consisted of 79 adjudicated male adolescents in a maximum-security facility. As hypothesized, adolescent male psychopaths had higher levels of sensation seeking, impulsivity, conduct disorder and oppositional defiant disorder. A discriminant function analysis found that sensation seeking, impulsivity, ADHD, Conduct Disorder, and Oppositional Defiant Disorder was moderately useful in classifying adolescent psychopathy. The results suggest that behavioral dysregulation is an important aspect of adolescent psychopathy. The relationship of these data to theories of adolescent psychopathy is discussed.
Adolescent self-mutilating behaviors: Experiential avoidance coupled with imitation?
Repetitive self-mutilation (RSM) has become increasingly prevalent among adolescents. Empirical research has pinpointed several correlates of this behavior, but the initiation and maintenance of RSM among adolescents are not well understood. The experiential avoidance model (EAM) proposes that self-mutilation is a behavior that allows for the avoidance or alteration of unwanted internal experiences, and that it is negatively reinforced with repetition. The current study explored the usefulness of the EAM as an explanatory theory for adolescent RSM, with the additional incorporation of issues of social context. Adolescents (N = 211) from three school-based samples completed self-report questionnaires. One-third of students reported at least one incident of purposeful, non-suicidal self-mutilation and 16% had engaged in self-mutilation repeatedly within the past 6 months. Both regression and group analyses indicated that adolescents who engage in RSM report greater psychological distress, a greater incidence of functionally equivalent behaviors, and greater exposure to self-mutilation among peers and/or in the media, when compared to their counterparts who have not engaged in RSM. Suicidal ideation/behaviors were consistently the strongest predictors of current self-mutilation behaviors. Clinical implications, limitations, and suggestions for future research are discussed.
The adolescent stress response to a naturalistic driving stressor
The proposed study examined the role of anxiety and risk-taking in driving performance in adolescents. In addition to examining the sample as a whole, gender differences were assessed given earlier reports from our laboratory and others indicating that males and females differ with respect to risky behaviors to driving performance and anxiety. Adolescents' subjective and physiological responses to a driving simulator task were assessed. Anxiety was measured via self report and salivary cortisol. Participants provided a baseline saliva sample and 3 post-task samples for cortisol analysis. Subjective anxiety scores were obtained at both baseline and following the driving stressor. Information concerning impulsivity, as well as other psychological constructs was also collected at baseline. Unlike the pilot study, there were no relationships (with or without respect to gender) between salivary cortisol and both self-reported anxiety (state and trait) or impulsively measures for this sample. These results suggest that this group of adolescents may not have been anxious about the driving task. This discrepancy may stem from error introduced by the smaller sample size obtained from the initial findings or to other factors remaining outside the parameters of the current study. The task did, however, induce a slight hypothalamic pituitary adrenal (HPA) axis response indicating some physiological arousal. Males had significantly higher cortisol levels at baseline than females and at time point 3 while approaching significance at time points 2 and 4. Females possessed significantly higher trait anxiety than males and all post task cortisol levels were positively correlated to age while time points 2 and 4 (with time point 3 approaching significance, p=0.09) were inversely correlated with Self Depreciation scores. Additionally, females had Persecutory Ideas scores that were also negatively correlated with cortisol at time points 3 and 4. For both the entire sample and males only, the correlation between post-task cortisol and driving performance was positive and approached significance (p=0.07 and p=0.08, respectively), suggesting that some HPA activation may be facilitative for successful driving task performance. Correlations between driving performance and psychological constructs were explored and discussed with and without respect to gender.
Adolescents' Perception of Parental Behavior toward Them and its Relationship with Sex, Delinquency, and Security
This study investigated adolescents' perception of parental behavior toward them and its relationship with sex, delinquency, and security. The subjects chosen for the study were sixty boys and sixty girls from eleventh grade English classes, and sixty boys and sixty girls from two institutions for juvenile delinquents. All subjects were white, they ranged in age from fifteen through eighteen years, and they had two living parents.
The adoption and use of electronic information resources by a non-traditional user group: Automotive service technicians.
The growing complexity of machines has led to a concomitant increase in the amount and complexity of the information needed by those charged with servicing them. This, in turn, has led to a need for more robust methods for storing and distributing information and for a workforce more sophisticated in its use of information resources. As a result, the service trades have "professionalized," adopting more rigorous academic standards and developing ongoing certification programs. The current paper deals with the acceptance of advanced electronic information technology by skilled service personnel, specifically, automotive service technicians. The theoretical basis of the study is Davis' technology acceptance model. The purpose of the study is to determine the effects of three external factors on the operation of the model: age, work experience, and education/certification level. The research design is in two parts, beginning with an onsite observation and interviews to establish the environment. During the second part of the research process a survey was administered to a sample of automotive service technicians. Results indicated significant inverse relationships between age and acceptance and between experience and acceptance. A significant positive relationship was shown between education, particularly certification, and acceptance.
Adoptive Parenthood: an Exploratory Study of the Influence of Pre-adoption Communication Satisfaction on Post-adoption Family Adjustment and Coping
There are over a million adopted children in the United States, which makes up over 2% of the population. in spite of the fact that the majority of children are adopted into loving and caring homes, early life trauma puts them at higher risk for developing behavioral and emotional problems than non-adopted children. Due to these issues, many adoptive parents encounter post-adoption stress. This stress is often linked to minimal education regarding short- and long-term challenges associated with adoption. the adoption agency is likely the best group for addressing challenges, yet few researchers have studied adoption agency communication and adoptive parent adjustment. in this study I examined pre-adoption communication satisfaction, post-adoption adjustment (life change and parental adjustment), and coping strategies. Hypothesis 1 questioned the relationship between adoptive parents’ pre-adoption communication satisfaction with their social workers and post-adoption family adjustment; this hypothesis was supported only for problems related to home and work life adjustment. Hypothesis 2 predicted coping strategies would mediate the relationship between communication satisfaction and family adjustment. H2 was not supported for both life change and parental adjustment. Research Questions 1a and 1b inquired about the coping strategy that had an impact on life change and parental adjustment; escape-avoidance coping was most common for problems related to parental difficulty adjustment. a second research question was added post hoc; it questioned if special needs adopted children had an impact on family adjustment. Results indicated the special needs designation is related to home and work life adjustment. After discussing the theoretical and practical implications of this study, I offer limitations and directions for future research.
The Adsorption of Radioactive Isotopes on Precipitates
This thesis concerns the investigation of radioisotopes as indicators for precipitation reactions. As a precipitate forms in the presence of a radioisotope, adsorption may take place on its surface. If this adsorption changes markedly at the stoichiometric point it will be possible to use this variation as an indicator for the reaction.
The Adsorption of Radioactive Isotopes on Specific Precipitates
The purpose of this investigation is to reveal the effects of certain factors affecting adsorption on some specific precipitates. It is hoped that the choice of precipitate types will enable extension of the information gained here to other precipitates similar to those investigated.
Adult attachment and posttraumatic growth in sexual assault survivors.
Posttraumatic growth, defined as positive psychological changes in the aftermath of adversity and suffering, is a relatively recent focus in psychological research. The addition of this concept to the literature has provided a new, more resiliency-based framework through which to view survivors of various forms of trauma. Despite estimates that over half of all sexual assaults are not reported to the authorities, current crime statistics indicate that 1 in 4 women are sexually assaulted in their lifetime (Campbell & Wasco, 2005). Given the large percentage of the population that is impacted by sexual assault, it is essential that professionals better understand the factors that influence the successful healing and growth that can occur post-trauma. The purpose of this study was to further expand the literature on posttraumatic growth in sexual assault survivors by considering this phenomenon through the lens of attachment theory. Specifically, this study tested a proposed model of the inter-relationships among subjective and objective perceptions of threat during the sexual assault, adult romantic attachment, and posttraumatic growth. It was hypothesized that adult romantic attachment and parent-child attachment would mediate the relationship between subjective, or perceived threat, defined as the victim's perception of life threat, and objective threat, defined as the severity of the sexually aggressive act perpetrated on the victim, and posttraumatic growth. Finally, it was hypothesized that subjective threat appraisal would better predict posttraumatic growth than objective threat appraisal. Contrary to hypotheses, results of the study indicated that adult romantic attachment and parent-child attachment did not mediate the relationship between subjective and objective threat appraisal and posttraumatic growth. Thus, both path analytic models were not viable. However, exploratory analysis indicated that both subjective and objective threat appraisal were directly related to posttraumatic growth, with subjective perceived threat appraisal accounting for more of the variance.
Adult Attachment Patterns, Mental Representation of Self, and Faith: Mediators of Childhood Trauma and Affect-Behavior Regulations in Adulthood
The purpose of this study was to investigate psychological mechanism by which four intra- and inter-personal characteristics of an individual (anxious and avoidant adult attachment patterns, images of self, and religious faith) mediate the relationship between childhood trauma and each of three affect-behavior regulation problems in adulthood (symptoms of depression, disordered eating behaviors, and substance abuse). A total of 401 college student participants completed a packet of 18 surveys including 10 surveys used in the present study. Structural equation modeling was used to test each of three hypothesized structural models (Depression, Eating Disturbances, and Substance Abuse). A series of multi-group analyses conducted to test if each of three hypothesized models is invariant across gender indicated no significant difference between females and males. Thus, the data were combined across gender to test for mediated effects in each of three hypothesized models. The results indicated: (a) for the hypothesized model for depression, anxious attachment patterns, avoidant attachment patterns, and negative self-images, but not religious faith, fully mediated the relationship between childhood trauma and symptoms of depression; (b) for the model for eating disturbances, anxious attachment and negative images of self, but not avoidant attachment and religious faith, fully mediated the association between childhood trauma and disordered eating behaviors; and (3) for the mode for substance abuse, anxious attachment and poor religious faith, but not avoidant attachment and negative self-images, fully mediated the relationship between childhood trauma and substance abuse. The findings of the present study have noteworthy implications for treatment. When clients who suffer from symptoms of depression, disordered eating behaviors, and/or substance abuse report a history of repetitive abuse and neglect by primary caregivers in childhood, clinicians need to assist clients in: (a) understanding an association of childhood maltreatment with affect-behavior regulation problems; (b) being aware of an impact of abuse and neglect by attachment figures in childhood on negative mental representations of self, insecure attachment patterns in close relationship, and poor religious faith; and (c) most importantly, deepening an understanding of how their negative images of self, anxious and avoidant adult attachment patterns, and/or poor religious faith and practices, rather than parental abuse and neglect in childhood itself, directly predict their presenting symptoms of depression, disordered eating behaviors, and/or substance abuse problems. In doing so, it is crucial for clinicians to provide clients with secure and comforting therapeutic atmosphere, focus on building trusting working relationship with clients, and be aware of how clients' transference and clinicians' own counter-transference interact with each other and influence therapeutic process and effectiveness. Several important limitations of the present study and implications for future studies were discussed.
Adult Client Outcomes: Differences Between Counselors with Education in Child Centered Play Therapy Versus Counselors Without Education in Child-Centered Play Therapy
Child-centered play therapists are taught unique relationship building approaches and therapeutic methods to utilize when working with children. The purpose of this study was to determine if adult clients counseled by child-centered play therapists would demonstrate greater positive therapeutic outcomes than adult clients who were counseled by non-educated child-centered play therapists. This study also attempted to determine if the play therapists' clients would show greater, significant improvement in any particular areas of client distress (i.e., depression/anxiety, relationship issues), more so than the clients of the non-play therapists. Archival data from an assessment, The Adult Self-Report Inventory (ASR), was gathered to measure reported pre and post-test client symptomology. This study utilized a 2X2 repeated measure ANOVA design to analyze the impact of counselors who were educated in child-centered play therapy who saw adult clients, versus their non-play therapy counterparts who saw adult clients. Before treatment pre-test and after treatment post-test administration was collected for use in the analysis. The population consisted of 60 adult clients seeking counseling services at a major university in the southwest. All clients were seen by Master's practicum students for ten sessions. The clients were divided into two groups - 30 were seen by play therapists, 30 were seen by non-play therapists. Five scales on the ASR were measured using a 2x2 split-plot design and Eta squared. There were three independent variables: group, measurement occasion, and the interaction between group and measurement. The results of this study did not reveal any statistical significance. However, clinical significance was demonstrated as the play therapists' clients did report greater reductions in symptomology on all five scales, some more than others.
Adult Education: in Retrospect and Prospect

Adult learner satisfaction with web-based non-credit workforce training.
Web-based training has become a billion dollar industry in the United States. Electronically aided learning is viewed by many companies as a cost-effective way to deliver the up-to-date, up-gradable job-related training that the industry is demanding. This study sought to examine the relationship between learners’ satisfaction with online training as it relates to learner readiness, online features, and course relevance. The population for this study was adults seeking non-credit workforce training, specifically library professionals who were involved in web-based training through the Lifelong Education @ Desktop (LE@D) program at the University of North Texas, Denton. Online methods of training are used most extensively in the area of mandatory or compliance training, in which 35 % of training is conducted mostly or completely online. The total potential library population using LE@D product to date is approximately 4,000 unique enrollments nationwide. Participants were selected from a complete list of unique LE@D users over a 90-day period. A survey instrument was sent via e-mail to 514 enrollees who had completed a recent LE@D online training course. In total, 254 participants responded to the survey. Bivariate analysis of the variables using the Pearson product-moment correlation was used to determine the occurrence and strength of a relationship between each of the three independent variables and the dependent variable in order to test the three research hypotheses. A regression model was used to explain how significantly the three independent variables, that is, online features, learner readiness, and course relevance, would have an impact on learner satisfaction. Results suggest that learner awareness of issues surrounding online features, learner readiness, and course relevance have a statistically significant impact on the overall satisfaction of the Web-based training event. As companies continue to adopt eLearning as a training investment, attention should be given to the end-users experiences. Employee responses to Web-based training are important because employee satisfaction is an indicator that a company’s training investment will result in positive outcomes.
Advance Directives in Texas: Advance Directives Act of 1999
Growth in the number of people living to very old age and progress in health care technology are creating important new challenges for our society. Among them is modern medicine's ability to extend some people's lives beyond the point where they are capable of making decisions or expressing their needs and desires, resulting in the very complex problem of knowing when to allow a person to die. In part, advance directives were created to solve this problem. Texas has been busy developing changes to existing state laws in an effort to create more "user-friendly" directives. This paper explores the history of advance directives, and discusses the details and nuances of the Texas Advance Directives Act of 1999.
Advanced Molecular and Microbial Techniques: a Complete Laboratory Notebook
The purpose of this project is to produce a complete and thorough notebook that may be used to supplement laboratory coursework. Its intent is to be used primarily by the students to aid them in understanding background information and the proper laboratory procedures involved in various types of experiments. The laboratory notebook is a summation of all the experiments and procedures used in the six-credit hour Advanced Microbial and Molecular Biology (BIOL 5160) course offered during the summer semester at the University of North Texas. This class is a team taught effort by Professors O'Donovan and Kunz. The course is constructed as an intensive practice exercise to teach the student about gene mutations, biosynthetic pathways, preparation and analysis of plasmid DNA, and many other topics included in the notebook.
Advanced Technology for Source Drain Resistance Reduction in Nanoscale FinFETs
Dual gate MOSFET structures such as FinFETs are widely regarded as the most promising option for continued scaling of silicon based transistors after 2010. This work examines key process modules that enable reduction of both device area and fin width beyond requirements for the 16nm node. Because aggressively scaled FinFET structures suffer significantly degraded device performance due to large source/drain series resistance (RS/D), several methods to mitigate RS/D such as maximizing contact area, silicide engineering, and epitaxially raised S/D have been evaluated.
Advancements in Instrumentation for Fourier Transform Microwave Spectroscopy
The efforts of my research have led to the successful construction of several instruments that have helped expand the field of microwave spectroscopy. The classic Balle-Flygare spectrometer has been modified to include two different sets of antenna to operate in the frequency ranges 6-18 GHz and 18-26 GHz, allowing it to function for a large range without having to break vacuum. This modified FTMW instrument houses two low noise amplifiers in the vacuum chamber to allow for the LNAs to be as close to the antenna as physically possible, improving sensitivity. A new innovative Balle-Flygare type spectrometer, the efficient low frequency FTMW, was conceived and built to operate at frequencies as low as 500 MHz through the use of highly curved mirrors. This is new for FTMW techniques that normally operate at 4 GHz or higher with only a few exceptions around 2 GHz. The chirped pulse FTMW spectrometer uses horn antennas to observe spectra that span 2 GHz versus the standard 1 MHz of a cavity technique. This instrument decreases the amount of time to obtain a large spectral region of relative correct intensity molecular transitions. A Nd:YAG laser ablation apparatus was attached to the classic Balle-Flygare and chirped pulse FTMW spectrometers. This allowed the study of heavy metal containing compounds. The instruments I constructed and the techniques I used have allowed the discovery of further insights into molecular chemistry. I have seen the effects of fluorinating an alkyl halide by determining the geometry of the carbon backbone of trans-1-iodoperfluoropropane and observing a ΔJ = 3 forbidden transition caused by a strong quadrupole coupling constant on this heavy molecule. The quadrupole coupling tensors of butyronitrile, a molecule observed in space, have been improved. The nuclear quadrupole coupling tensor of difluoroiodomethane was added to a list of variably fluorinated methyl halides upholding a trend for the magnitude of χzz. The study of SrS led to the determination of the Born-Oppenheimer breakdown terms and improving the precision of the SrS internuclear distance. I have also conducted the first pure rotational spectroscopic investigation on an actinide containing molecule, ThO.

The Adventist Movement in Trinidad: A Case-Study in Intercultural Communication
The problem with which this study is concerned is that of devising methods to assist teachers of Christianity in reaching and attracting a fast-growing and enlightened country. The Adventist church, along with other churches, is being challenged in communicating its message to a populace consisting of varied ethnic groups. This investigation has a two-fold purpose: (1) to study intercultural communications in order to locate principles which are applicable to missionary endeavors, and (2) to place these principles at the disposal of missionary personnel for their selective use in disseminating the beliefs of Christianity.

This thesis discusses the life of Winston Churchill. It explores his adventures and political reform prior to 1913.
Adventure Based Counseling: Exploring the Impact of Abc on Adaptive Functioning in High School Males
The purpose of this study was to examine the impact of ABC on adaptive functioning in high school males. Specifically, a pretest/posttest, experimental design (N = 46; Caucasian = 26, Hispanic = 20) was used to examine the changes in adaptive and maladaptive functioning in ABC participants (n = 21) compared to those in a control/waitlist group (n = 25) as measured by the Behavior Assessment System for Children, second edition (BASC-2). Participants randomly assigned to the treatment group engaged in 10 ABC sessions. In order to better understand group process in ABC, I had experimental group participants complete the Group Climate Question Short form (GCQ-S) three times during the intervention. A mixed between/within subjects ANOVA of the BASC-2 scores revealed a statistically significant increase in adaptive functioning for both groups, F(1, 33) = 8.58, p < .01, with a partial eta squared of .21 indicating a large effect. There was no statistically significant difference between the experimental and control/waitlist groups, F(1, 33) = .064, p = .80, and a very small effect size (partial eta squared < .01). A repeated measures ANOVA of the GCQ-S scores revealed a statistically significant increase in engagement, F(2, 38) = 4.067, p = .025, with an eta squared of .21, indicating a large effect. Limitations of the study, implications of the results for practice, and recommendations for future research are presented.
Advertising and Promotional Procedure as Practiced by Five Dallas Department Stores

After observing their advertising methods, an attempt will be made to conclude whether their efficiency might be increased through use of different advertising and promotional policies.
Aerospace and Defense Industries Online Recruiting of College and University Graduates: Strategies Toward Defining a Comprehensive Informational Benchmark
This qualitative, inductive study analyzed online recruiting information posted at the websites of five major aerospace and defense corporations to recruit college juniors, seniors, and recent graduates. Recruitment of this group is critical to staff the personnel for the scientific, technical, and management needs of aerospace and defense industries. The study sought: (1) to determine the use of multiple recruitment factors inferred from the literature and recommended for successful recruitment of college graduates, (2) to determine use of online social media (Facebook, Twitter, LinkedIn) to recruit this population, and (3) to explore commonalities among these corporations regarding online recruiting information to determine if a model for online recruitment now exists. A matrix of recruitment factors was developed from a review of the literature on the personnel needs of this industry and on effective recruiting factors for this group. Content analysis involved filtering information at each website with the matrix. Conclusions of this study include: (1) the matrix of recruitment factors and the rating scale developed for the purposes of this study provide a tool for researching, documenting, and comparing recruitment information on the internet; (2) that while these corporations represent the latest applications in technology in their manufacturing processes and products, they do not use social networking technology to the extent the popular and scholarly literature indicate is typical for the target group. Given that the current generation exhibits extensive use of social media, several of these corporations’ websites appear not to utilize this networking technology. Informally, these corporations argue that cyber-security prevents extensive use of social networking sites. Thus, these corporations must determine how to maintain cyber-security while at the same time adopting more accepted use of social networking platforms.
Aesthetic and Technical Analysis on Soar!
Soar! is a musical composition written for wind ensemble and computer music. The total duration of the work is approximately 10 minutes. Flocking behavior of migratory birds serves as the most prominent influence on the imagery and local structure of the composition. The cyclical nature of the birds' journey inspires palindromic designs in the temporal domain. Aesthetically, Soar! portrays the fluid shapes of the flocks with numerous grains in the sounds. This effect is achieved by giving individual parts high degree of independence, especially in regards to rhythm. Technically, Soar! explores various interactions among instrumental lines in a wind ensemble, constructs overarching symmetrical structures, and integrates a large ensemble with computer music. The conductor acts as the leader at several improvisational moments in Soar! The use of conductor-initiated musical events in the piece can be traced back through the historic lineage of aleatoric compositions since the middle of the twentieth century. [Score is on p. 54-92.]
Aesthetic Models and Structural Features in Concerto for Solo Percussion and Concert Band
Concerto for Solo Percussion and Concert Band was commissioned by Staff Sergeant Rone Sparrow, a percussionist with the West Point Military Academy Band. Funding for the project was provided by the Barlow Foundation. The piece was premiered April 13, 2005 in the Eisenhower Hall Theater at West Point, New York. Rone Sparrow performed with the USMA band, and Colonel Thomas Rotondi Jr., Commander/Conductor, conducted the piece. The concerto consists of three movements, and each movement features a different instrument: the first features marimba, the second, vibraphone, and the third movement features the drum kit together with a rhythm section (piano, bass, and drums). In addition to the piece, the dissertation paper discusses important technical detail related to the piece, including: harmony, form, rhythm, programmatic ideas as they relate to motivic strands, and the process of generating and discarding material. The paper also focuses on a number of factors that were influential to the piece, such as postmodern philosophy.
Aesthetics in the Popular Culture
The purpose of this thesis is to consider three opposing statements regarding aesthetics in our popular culture. The first statement is that the youth of this age are demolishing the old standards of aesthetic taste and are creating a nonaesthetic; the second statement is that the youth are enlarging the vision and scope of the accepted standard of aesthetic and changing its direction; the thrid statement is that the creations of the youth in our popular culture of today are neither new nor nonaesthetic, but merely a continuation of aesthetics as they are accepted. One statement will be chosen as the most valid of the three.
The Aesthetics of Minimalist Music and a Schenkerian-Oriented Analysis of the First Movement "Opening" of Philip Glass' Glassworks
Philip Glass' Glassworks (1981) is a six-movement composition for two flutes, two soprano saxophones/clarinets, two tenor saxophones/bass clarinets, two French horns, violas, cellos, and the DX7 electric piano. Glassworks consists of six movements titled "Opening," "Floe," "Island," "Rubric," "Facades," and "Closing." This thesis covers the first movement "Opening." Repetition in musical minimalism confronts traditional prescriptive codes of tonal music and post-tonal music. While challenging the traditional codes, repetition in musical minimalism established new codes for listening to minimal music. This thesis explores the implications of these ideas.
The Affect of Mobile Performance Support Devices on Anxiety and Self-Efficacy of Hospital Float Staff
Floating describes the act of staff moving from one unit to another based on the needs of the patients in a hospital. Many staff who float to different units express negative feelings, including anxiety and lack in self-efficacy. However, floating is both an economical and efficient method to use staff across the hospital, especially with current staffing shortages in the United States. This study investigated how the use of mobile performance support devices may help reduce anxiety and increase self-efficacy for those staff who float to different units. with access to multiple resources available on the mobile device, Bandura's social learning theory and self-efficacy concept set the framework through modeling, observing, and imitating others in order to reproduce certain behaviors and tasks and believe in one's capability to perform. a quantitative study incorporating the retrospective pretest-posttest design was conducted using the population of float staff, including both nurses and respiratory therapists, from Children's Medical Center of Dallas. Both the State-Trait Anxiety Inventory and General Self-Efficacy Scale, along with a basic demographic tool, were used to explore anxiety and self-efficacy in relation to the usage of mobile performance support devices. Findings can be used to impact the negative feelings of staff towards the idea of floating.
Affective and cognitive components of job satisfaction: Scale development and initial validiation.
Job satisfaction is one of the most commonly studied variables in the organizational literature. It is related to a multitude of employee-relevant variables including but not limited to performance, organizational commitment, and intent to quit. This study examined two new instruments measuring the components of affect and cognition as they relate to job satisfaction. It further proposed including an evaluative (or true attitudinal) component to improve the prediction of job satisfaction. Results provide some evidence of both two and three factor structures of affect and cognition. This study found minimal support for the inclusion of evaluation in the measurement of job satisfaction. Affect was found to be the single best predictor of job satisfaction, regardless of the satisfaction measure used. Further development is needed to define the factor structures of affect and cognition as well as the role of these factors and evaluation in the prediction of job satisfaction.
Affective Forecasting: the Effects of Immune Neglect and Surrogation
Studies of affective forecasting examine people’s ability to predict (forecast) their emotional (affective) responses to future events. Affective forecasts underlie nearly all decisions people make and the actions they take. However, people engage in systematic cognitive errors when making affective forecasts and most often overestimate the intensity and duration of their emotional responses. Understanding the mechanisms that lead to affective forecasting errors (e.g., immune neglect) and examining the utility of methods for improving affective forecasting errors (e.g., surrogation) can provide highly valuable information for clinicians as they assist clients in determining their goals both for therapy and for life. The first purpose of the current study was to determine if affective forecasting errors due to immune neglect lead to misjudgments about the relative emotional impact of minor versus moderate negative experiences (i.e., trauma severity). The second purpose was to examine the utility of surrogation for improving affective forecasts. Potential interaction effects between these two variables were also examined. The current study utilized a 2 (Trauma Severity: minor, moderate) X 3 (Prediction Information: surrogation information only, simulation information only, both types of information) experimental design. Undergraduates were recruited via the SONA system and randomly assigned to one of the six experimental conditions. A preliminary study was conducted to obtain surrogation information for use in the main study. All participants in the main study predicted how they would feel 10 minutes after receiving negative personality feedback, using a 10-point scale ranging from (1) very unhappy to (10) very happy. These predictions constitute their affective forecasts. All participants then actually received the negative personality feedback (ostensibly from another participant, a peer, in a nearby room) and reported their actual affective states ten minutes later, using the same scale. These ratings constitute their affective reports. Affective forecasting error was calculated as the difference between affective forecasts and affective reports. Results showed the affective forecasts of participants in the moderate trauma severity condition were significantly less accurate than those of participants in the minor trauma severity condition, providing evidence of immune neglect. Surrogation information significantly improved the accuracy of affective forecasts when participants were deprived of simulation information. Limitations of the current study and implications of the findings are discussed.
Affective Reactions and Psychosocial Functioning in the Course of Psycho-Educational Assessment
Every day, children throughout the United States are given psychological evaluations for many different clinical and psycho-educational purposes. Very little research has attempted to investigate children's responses to the experience of having intellectual and achievement tests administered. The goal of the current research was to explore the effect a psycho-educational evaluation has on children in areas of self-concept and anxiety. Dependent variables consisted of pre- and post-test measures of anxiety and self-concept. A total of 75 children in the 4th 5th and 6th grades were recruited after referral for evaluation and possible placement in the Talented and Gifted Program or Special Education. This study employed Analysis of Variance (ANOVA), t-tests, multiple regression analysis, and correlational analysis. Findings included initial evidence that children endorsed decreased anxiety after psycho-educational assessments rather than increased anxiety, suggesting that fear of unknown situations may be more anxiety provoking than the actual situation itself, potentially beneficial findings for psychology and psychometric professionals who evaluate children daily. Students endorsement of academic self-concept significantly predicted anxiety after a psycho-educational evaluation, indicating that students who feel capable in academic areas may endorse less anxiety after an evaluation than students who do not feel academically capable. Finally, negative verbal interaction with parents significantly predicted lower general self-concept scores, providing evidence that the manner in which parents verbally relate to their children may have significant impact for the mental health of children.
Affordances of external representations in instructional design: The effect of narrative and imagery in learning.
Consisting of both theoretical and empirical inquires, this study examines the primary functions of narrative and the relationship between narrative and mental imagery. The study proposes a new framework to interpret semiotic resources. Combining this with the linguistic functional theory of Halliday (1978), a functional method to empirically investigate semiotic representations was also developed. In the empirical inquiry, the study developed a latent construct method to empirically test the effects of narrative in a real learning situation. This study is the first to investigate the functional relationship between narrative and mental imagery, and among the first to suggest a theory and empirically investigate representations of a multimodal nature. The study is also among the first to use latent constructs to investigate the learning experience in a real educational setting. Data were collected from 190 library professionals who enrolled in three sections (two in narrative and one in plain text) of an online course administered through Vista 4.0 and who completed the course and responded to several instruments. Essay data (n = 82 x 2) were analyzed using content analysis based on the narrative analysis framework developed. Quantitative data analysis methods include univariate data analysis, factor analysis, and structural equation modeling that tests the proposed model and verifies the relationships between the latent variables. Overall, the findings support the hypotheses about the functional effects of narrative identified, and narrative is found to provide a favorable and positive learning context which is tested by the proposed model of learning experience measured by several latent constructs (X2 = 31.67, df = 47, p = .9577, RMSEA = .00, SRMR = .047, NNFI = 1.05, CFI = 1.00, and GFI = .94). The results indicate that participants who enrolled in the narrative sections of the course gained higher creative scores and showed better results in performance-based and attribution-based experiences. The model testing results indicate that even though more time spent during learning led to better outcome and performance in both groups, more time spent means more satisfaction for the individuals in the narrative group, but led to less satisfaction for the individuals in the non-narrative group.
Affordances of Instrumentation in General Chemistry Laboratories
The purpose of this study is to find out what students in the first chemistry course at the undergraduate level (general chemistry for science majors) know about the affordances of instrumentation used in the general chemistry laboratory and how their knowledge develops over time. Overall, students see the PASCO™ system as a useful and accurate measuring tool for general chemistry labs. They see the probeware as easy to use, portable, and able to interact with computers. Students find that the PASCO™ probeware system is useful in their general chemistry labs, more advanced chemistry labs, and in other science classes, and can be used in a variety of labs done in general chemistry. Students learn the affordances of the probeware through the lab manual, the laboratory teaching assistant, by trial and error, and from each other. The use of probeware systems provides lab instructors the opportunity to focus on the concepts illustrated by experiments and the opportunity to spend time discussing the results. In order to teach effectively, the instructor must know the correct name of the components involved, how to assemble and disassemble it correctly, how to troubleshoot the software, and must be able to replace broken or missing components quickly. The use of podcasts or Web-based videos should increase student understanding of affordances of the probeware.

African-American parents' nutritional habits: Implications for the prevention of early childhood obesity.
This research study addressed the nutritional beliefs and habits of African-American parents of children aged 3 to 6 years old. Both quantitative and qualitative data collection methods were employed. Quantitative data was collected via the Comprehensive Feeding Practices Questionnaire as well as a demographic questionnaire. Qualitative data was collected from oral interviews conducted by the researcher. Seventy-five parents or guardians participated in the study. Findings for the research questions revealed the participants' beliefs about nutrition directly correlated with food they provided for their children and most believed nutrition rather than genetics played a role in their child(ren)'s weight. Furthermore, parents from lower income families consumed more home cooked meals per week and those with higher incomes did not consume more fast food per week. Food intake restriction and control in feeding was similar among all participants, regardless of restriction and control in feeding was similar among all participants, regardless of education or income level. Suggestions for future research were included.
African Refugee Parents' Involvement in Their Children's Schools: Barriers and Recommendations for Improvement
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to examine involvement of African refugee parents in the education of their elementary school children. The setting of the study was Northern and Southern Texas. African refugee parents and their children's teachers completed written surveys and also participated in interviews. In the study's mixed-method design, quantitative measures provided data about parent involvement at home, parent involvement at school, frequency of parent-teacher contact, quality of parent-teacher relationship, parent endorsement of children's schools, and barriers to parent involvement. Qualitative data from the open-ended questions provided data on barriers and strategies to improve involvement. Sixty-one African refugee parents responded to the survey and also participated in an in-depth face-to-face or telephone interview. Twenty teacher participants responded to an online survey. Quantitative data gathered from the parent and teacher surveys were analyzed using frequency distributions and analyses of variance. Qualitative data were analyzed by summarizing and sorting information into different categories using Weft QDA, an open-source qualitative analysis software. From these data, I identified barriers to African refugee parent involvement in their children's schools, as well as challenges that teachers face as they try to involve African refugee parents. Results of analyses of variance revealed statistically significant differences in parent involvement between African refugee parents with limited English proficiency and those with high English proficiency. A key finding of the research was that, whereas the overall level of parent involvement for African refugee parents was low, a major barrier to involvement was language. Teachers and parents cited enrolment in English as a second language programs as the best strategy to enhance parent involvement of African refugees. Additionally, parents who reported higher education levels were more involved in their children's education both at home and at school. All groups of African refugee parents reported high endorsement of their children's school. Strategies suggested to improve involvement include the use of interpreters and parent education on importance of involvement.
The Afro-British Slave Narrative: The Rhetoric of Freedom in the Kairos of Abolition
Access: Use of this item is restricted to the UNT Community.
The dissertation argues that the development of the British abolition movement was based on the abolitionists' perception that their actions were kairotic; they attempted to shape their own kairos by taking temporal events and reinterpreting them to construct a kairotic process that led to a perceived fulfillment: abolition. Thus, the dissertation examines the rhetorical strategies used by white abolitionists to construct an abolitionist kairos that was designed to produce salvation for white Britons more than it was to help free blacks. The dissertation especially examines the three major texts produced by black persons living in England during the late eighteenth centuryIgnatius Sancho's Letters of the Late Ignatius Sancho (1782), Ottobauh Cugoano's Thoughts and Sentiments on the Evil of Slavery (1787), and Olaudah Equiano's The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African (1789)to illustrate how black rhetoric was appropriated by whites to fulfill their own kairotic desires. By examining the rhetorical strategies employed in both white and black rhetorics, the dissertation illustrates how the abolitionists thought the movement was shaped by, and how they were shaping the movement through, kairotic time. While the dissertation contends that the abolition movement was rhetorically designed to provide redemption, and thus salvation, it illustrates that the abolitionist's intent was not merely to save the slave, but to redeem blacks first in the eyes of white Christians by opening blacks to an understanding and acceptance of God. Perhaps more importantly, abolitionists would use black salvation to buy back their own souls and the soul of their nation in the eyes of God in order to regain their own salvation lost in the slave trade. But ironically, they had to appear to be saving others to save themselves. So white abolitionists used the black narratives to persuade their overwhelmingly white audience that slavery was as bad for them as it was for the African slave. And in the process, a corpus of black writing was produced that gives current readers two glimpses of one world.
After the Planes
The dissertation consists of a critical preface and a novel. The preface analyzes what it terms “polyvocal” novels, or novels employing multiple points of view, as well as “layered storytelling,” or layers of textuality within novels, such as stories within stories. Specifically, the first part of the preface discusses polyvocality in twenty-first century American novels, while the second part explores layered storytelling in novels responding to World War II or the terrorist attacks of 9/11. The preface analyzes the advantages and difficulties connected to these techniques, as well as their aptitude for reflecting the fractured, disconnected, and subjective nature of the narratives we construct to interpret traumatic experiences. It also acknowledges the necessity—despite its inherent limitations—of using language to engage with this fragmentation and cope with its challenges. The preface uses numerous novels as examples and case studies, and it also explores these concepts and techniques in relation to the process of writing the novel After the Planes. After the Planes depicts multiple generations of a family who utilize storytelling as a means to work through grief, hurt, misunderstanding, and loss—whether from interpersonal conflicts or from war. Against her father’s wishes, a young woman moves in with her nearly-unknown grandfather, struggling to understand the rifts in her family and how they have shaped her own identity. She reads a book sent to her by her father, which turns out to be his story of growing up in the years following World War II. The book was intercepted and emended by her grandfather, who inserts his own commentary throughout, complicating her father’s hopes of reconciliation. The novel moves between two main narratives, one set primarily in 1951 and the other in the days and weeks immediately prior to September 11, 2001.
After the Storm: an Adaptation of Sobre las Ruinas, by Roberto J. Payró

This study is another phase of the overall research program designed to furnish basic information for the management of East Texas lakes and has as its specific purpose the determination of the age and growth characteristics of two valuable species on these waters. The species to be considered are the black crappie, Pomoxis nigro-maculatus (Le Sueur) and the white crappie, Pomoxis annularis Rafinesque. Both species are highly regarded as food fish and have for many years offered recreational outlets for Texas fishermen.
Age and Responses to the Events of September 11, 2001
Following the terrorist attacks on the United States on September 11, 2001, many turned to the field of psychology for greater understanding of the impact of such events and guidance in supporting our citizens. This study sought to gain greater understanding of the differential impact of the September 11th attack on individuals by investigating the influence of age, psychological hardiness, and repression versus sensitization as forms of coping behavior on psychological health. Both an initial cross-sectional sample (172 young adults & 231older adults) and a short-term longitudinal follow-up (39 young adults & 58 older adults) were included in the study. Older age, psychological hardiness and the use of a repressing coping style were found to each individually relate to greater resilience/less dysfunction at both time one and two. For young adults, high hardy repressors faired best, followed by high hardy sensitizers. Low hardy young adults demonstrated similar levels of dysfunction regardless of coping style (repressions/sensitization). For older adults, coping style impacted both high and low hardy individuals equally, with high hardy repressors demonstrating greater functioning. This study attempted to gain greater insight into explanations for these and previous findings of greater resilience among older adults. In explaining the greater resilience of older adults, it seems that coping style is highly important, while hardiness and the impact of history-graded events does not explain the resilience of older adults.
Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
GABAA receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer implants containing the GABAA receptor antagonist bicuculline were placed over barrel cortex for a 4-day period in young (postnatal days 8 - 12) and adult rats. In the cortex of young, but not adult rats, the chronic blockade of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.
