This study explored how various intrapersonal, familial, and life-goal characteristics related to the academic and personal success of first semester early college entrants attending the Texas Academy of Mathematics and Science (TAMS) at the University of North Texas. The study sought to identify which intrapersonal factors and external factors affected grades, behavioral markers, and life satisfaction during the students' first semester at TAMS. Baseline data from TAMS entrance material such as standardized achievement test scores, previous grade point averages (GPA's), advanced courses taken, and other academic activities and awards were collected. Data were also collected from the students prior to their entry to the start of TAMS related to family cohesiveness, motivation, and career goals. Data from parents were gathered prior to the start of TAMS regarding parenting styles, demographics, parents' educational levels, careers, and income levels, as well as the child's homework, extracurricular activities, and other time demands. First semester grades, a measure of life satisfaction since the program began, and behavior reports from staff members were used as outcome/success indicators. These additional data were used to examine the relationship between success and familial/interpersonal/life goal factors.

Two hundred twenty individuals participated in the present study from a university population. The study examined the relationship among attachment styles to caregivers, relationship with God, depressive symptomology, and depressive experiences. Attachment theorists have suggested a connection between childhood attachment to caregivers and current attachment to God through the idea that individuals have "working models" that form how they interpret present relationships. For the most part, the results of the current study supported the idea of correspondence between attachment to caregiver and attachment to God. Individual attachment styles to caregivers matched their attachment style to God. However, when caregiver religiousness was included as a moderating variable, results supported the theory of combined compensation-correspondence for those with insecure attachments to caregivers. Individuals with insecure attachment to caregivers were more likely to compensate for their insecure attachment bonds through participation in religious activity, whereas their internal, private relationship with God corresponded with their previous insecure attachment bonds. Individuals with insecure attachment to caregivers were more likely to endorse symptoms of depression and report introjective, but not anaclitic, depressive experiences. With respect to attachment to God, introjective depressive experiences were positively related to both anxious and avoidant attachments, whereas, anaclitic depressive experiences were …

The issue of effortful patient performance has been an area of clinical interest in individuals with minor traumatic brain injury (mTBI). Clinical attention to this area has increased largely because of an increase in the number of worker's compensation claims, injury-related lawsuits and/or insanity defense pleas. As patients are presented with the opportunity for secondary gain, the issue of optimum performance on neuropsychological measures becomes salient. In addition to neurocognitive deficits, there are psychological characteristics associated with mTBI including depression, emotional disturbance, personality changes, and other psychopathology. This study utilized the MSVT, a set of standard neuropsychological instruments, and the Minnesota Multiphasic Inventory-2 (MMPI-2) to investigate the relationships between effort, psychological characteristics, and neuropsychological functioning in individuals with minor traumatic brain injuries. The first objective of this study was to determine which psychological factors were related to effort in mTBI. The second objective was to determine if there were differences between groups that performed poorly on effort testing and groups that performed adequately on effort testing, based on relevant psychological characteristics. The results of the analyses supported the first hypothesis. Hysteria was inversely related to effort, and Mania was positively related to effort on one of five measures of effort. …

This dissertation examined the effects of academic interventions on the development of reading academic competence in fourth grade students who performed at or below grade level as determined by TAKS reading scale scores. Fifty students in fifth grade were chosen to participate in the study from five elementary schools in the Fort Worth Independent School District in Fort Worth, Texas. Only 46 students completed the study. The study was conducted with a control (n = 23) and treatment group (n = 23). The fourth grade students were administered pretests and posttests using the ACES and the fourth grade TAKS reading test. This quantitative study used a quasi-experimental design to answer the research questions. The final data results did not indicate that the implementation of interventions significantly increased TAKS reading scores at the p > .05 level. In addition, there were no significant increases at the p > .05 level between the ACES pretests and posttests. Although there were no significant gains on the TAKS or ACES, there are implications the interventions had a positive effect on teacher perceptions of their students' academic competence and some growth was evident for the treatment groups on both TAKS and ACE.

This study analyzes the satisfaction of doctoral students in the joint doctoral program in Christian higher education between Dallas Theological Seminary (DTS) and the University of North Texas (UNT). The study focuses on the 18 students who have been identified as advanced participants in or graduates from the joint program from its inception in 1997 through its 10-year mark in 2007. Fourteen of the 18 eligible students agreed to participate in this study for a 77.8 % response rate. The doctoral students completed a survey that was created using a study of Garrett in 2006 of doctoral students at Historically Black Colleges and Universities and of McLaughlin in 2002 of graduate students in Christian education at DTS. The purpose of this study was to determine to what extent the joint doctoral program in higher education between both institutions meets the expectations of the students and prepares them for the range of careers that they then pursue. The study offers a number of findings surrounding the five research questions and offers several conclusions and recommendations for further research. The study concluded that the surveyed participants were immensely satisfied with their education experience thus assuming that the joint program does meet expectations …

Clinical research suggests that adolescent offenders often do not view their criminal behaviors as problematic and, therefore, are not motivated for treatment. Although customarily defined as a static characteristic, the transtheoretical model (TTM) proposes treatment amenability is dynamic and can be achieved through tailored interventions that motivate individuals for treatment. The current study examines the predictive validity of TTM measures for adolescent offenders at a maximum security correctional facility. In particular, the Stages of Change Scale (SOCS) and Decisional Balance for Adolescent Offenders (DBS-AO) were compared with a more traditional assessment tool utilized in evaluating treatment amenability of juvenile offenders (i.e., Risk-Sophistication-Treatment Inventory; RSTI). One hundred adolescent offenders from the Gainesville State School completed two waves of data collection with a 3-month time interval. Information was collected on offenders' treatment progress between waves. Consistent with TTM research, predictors of treatment progress included low scores on the Cons scale on the DBS-AO and on the Precontemplation scale on the SOCS. Participants in the most advanced levels of treatment also scored high on the Sophistication-Maturity scale on the RSTI and the Impression Management scale on the Paulhus Deception Scale.

The current study examined the relationships among attachment styles to parent, peer, and romantic partner, ability to regulate emotion, as well as engagement in sexual behaviors and substance use. Attachment theory and previous research suggests that an individual learns how to manage emotions through the modeling of appropriate techniques and a stable sense of self-worth. These two aspects develop through a secure attachment bond with an important figure. When an individual does not have a secure attachment bond in which to practice adaptive affect regulation strategies, he/she may attempt to manage emotions through external means, such as sexual behaviors or substance use. Overall, results supported these associations, with some notable exceptions. Across attachment sources a secure attachment style was related to lower levels of psychological distress and less engagement in substance use. In contrast to the findings from earlier studies, affect regulation did not mediate the relationship between attachment and substance use, and engagement in sexual behaviors was not significantly related to either attachment style or affect regulation.

Computer technology has been used in education for years, and the government budgets large amounts of money to foster technology. However, it is still a debated whether computer technology makes a difference in students' learning outcomes. The purpose of this study is to find if any relationship exists between computer use by teachers and students and the students' academic achievement in math and reading for both traditional populations and English language learner (ELL) tenth graders. Computer use in this study included the computer activities by students and teachers, in terms of the time, frequency, activities types, the places students use computers, teachers' computer activities, and the training teachers received. This study used data gathered from tenth grade students from the dataset Education Longitudinal Study of 2002 (ELS:2002) of the National Center for Education Statistics (NCES). Fifteen thousand, three hundred and sixty-two students were randomly selected to represent all U.S. tenth-graders attending schools in 2002. The findings showed diverse relationships consistent with the literature. Based on the findings, some suggestions were made to teachers and parents about the quality of school work and computer use by students and teachers.

This two-part study investigates the effectiveness of neurofeedback training for reducing behavioral problems commonly observed in abused/neglected children, and compares its efficacy to other treatment interventions with this population. Neuro-developmental sequelae of early relationship trauma are explored as an etiological framework for understanding disturbed affect-regulation, which appears central to the behavioral and emotional difficulties commonly experienced by this pediatric population. It is suggested that neurofeedback teaches children to self-regulate brain rhythmicity mechanisms, which in turn affects global improvements in behavior and mood. The pilot study utilizes records of 20 children removed from their biological homes by Child Protective Services. Children were assessed prior to treatment using the Child Behavior Checklist (CBCL) and the Test of Variables of Attention (TOVA), and again after 30 sessions of individualized, qEEG-guided neurofeedback training. A t-test analysis of pre- and post-scores was computed, and indicated significant improvements following treatment. A meta-analysis of existing literature on treatment interventions with abused/neglected children provides individual and aggregate effect sizes for 33 outcome studies with this clinical population, and contextualizes the results of the present pilot study within other empirically validated treatment modalities. Establishment of an overall effect size for treatment for this pediatric population provides a needed method …

Cardiac, metabolic and growth response of early-stage chicken embryos to perturbations in yolk environment was investigated. Also, effects of parental hypoxia exposure on hypoxia resistance, thermal tolerance and body length of zebrafish larvae were investigated. In the first study, thyroxine, triiodothyronine and testosterone produced differential effects on heart rate and development rate of chicken embryos during the first 4 days of development. Triiodothyronine caused a dose-dependent increase in heart rate when applied at 40 or 70 hours of age, while thyroxine caused a dose-dependent increase in heart rate when applied at 40 hours only. Testosterone and propyl-thiouracil (deiodinase antagonist) did not have an effect on heart rate. Development rate was not changed by thyroxine, triiodothyronine, testosterone or propyl-thiouracil, which suggested that heart rate changes did not result from changes in embryo maturity. In the second study, chicken embryos exposed to yolks of different bird species during early-stage embryonic development showed changes in heart rate, mass-specific oxygen consumption and body mass that scaled with the egg mass, incubation period length, and yolk triiodothyronine and testosterone levels of the species from which yolk was derived. In the third study, this phenomenon was investigated between layer and broiler chickens. Heart rate, oxygen consumption …

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.

This qualitative study described and examined the characteristics, components and theoretical design of the Student African-American Brother (SAAB). The SAAB is a national program that seeks to increase the academic and social integration of African-American males in higher education to increase their potential to graduate with an undergraduate degree. The SAAB's academic and social integration strategies were compared to Bean and Bennett's conceptual model of black student attrition to determine the congruency between the organization's strategies and the theoretical framework. The methodology was case study. Thirty semi-structured interviews were held with past and current members of the organization to gain a broader knowledge of the SAAB strategies and interventions used to promote their academic and social integration. The research revealed the SAAB applies a three dimensional approach which consists of providing a supportive environment, supporting academic goals, and encouraging campus and community involvement. This approach increases the students' understanding of the organization and structure of the higher education setting to yield successful matriculation through a four year college or university.

George Crumb (b.1929)'s Makrokosmos is recognized as one of the masterpieces of twentieth century piano writing. Inexplicably, volume four of Makrokosmos, Crumb's only four-hand piano piece, is rarely studied by Crumb scholars. According to Crumb's program notes, his Makrokosmos is meant to be a hybrid of piano and orchestral sound. Crumb devised a list of signs and abbreviated letters to explain his specific instructions to the performers. The pianists who plan to perform Makrokosmos need to study Crumb's notations carefully in order to faithfully realize the composer's intentions. This dissertation examines the composer's treatment of four hands at the piano. In addition, a performer's analysis and practical "translation" of these techniques is provided, in the hopes of rendering this amazing piece more accessible to pianists in search of new and wonderful repertoire for piano four hands. It is also hoped that future composers will be inspired by Crumb's innovations and imaginative ideas.

In recent years, advances in computer technology combined with new ab initio computational methods have allowed for dramatic improvement in the prediction of energetic properties. Unfortunately, even with these advances, the extensive computational cost, in terms of computer time, memory, and disk space of the sophisticated methods required to achieve chemical accuracy - defined as 1 kcal/mol from reliable experimental data effectively - limits the size of molecules [i.e. less than 10-15 non-hydrogen atoms] that can be studied. Several schemes were explored to help reduce the computational cost while still maintaining chemical accuracy. Specifically, a study was performed to assess the accuracy of ccCA to compute atomization energies, ionization potentials, electron affinities, proton affinities, and enthalpies of formation for third-row (Ga-Kr) containing molecules. Next, truncation of the correlation consistent basis sets for the hydrogen atom was examined as a possible means to reduce the computational cost of ab initio methods. It was determined that energetic properties could be extrapolated to the complete basis set (CBS) limit utilizing a series of truncated hydrogen basis sets that was within 1 kcal/mol of the extrapolation of the full correlation consistent basis sets. Basis set truncation for the hydrogen atom was then applied to …

Oxygen deprivation can be pathological for many organisms, including humans. Consequently, there are several biologically and economically relevant negative impacts associated with oxygen deprivation. Developing an understanding of which genes can influence survival of oxygen deprivation will enable the formulation of more effective policies and practices. In this dissertation, genes that influence adult anoxia survival in the model metazoan system, C. elegans, are identified and characterized. Insulin-like signaling, gonad function and gender have been shown to influence longevity and stress resistance in the soil nematode, C. elegans. Thus, either of these two processes or gender may influence anoxia survival. The hypothesis that insulin-like signaling alters anoxia survival in C. elegans is tested in Aim I. The hypotheses that gonad function or gender modulates anoxia survival are tested in Aim II. Insulin-like signaling affects anoxia survival in C. elegans. Reduction of insulin-like signaling through mutation of the insulin-like receptor, DAF-2, increases anoxia survival rates in a gpd-2/3 dependent manner. The glycolytic genes gpd-2/3 are necessary for wild-type response to anoxia, and sufficient for increasing anoxia survival through overexpression. Gonad function and gender both affect anoxia survival in C. elegans. A reduction of ovulation and oocyte maturation, as measured by oocyte flux, …

In this work, I studied the hybrid system based on self-assembled guanosine crystal (SAGC) conjugated to wide-bandgap semiconductor gallium nitride (GaN). Guanosine is one of the four bases of DNA and has the lowest oxidation energy, which favors carrier transport. It also has large dipole moment. Guanosine molecules self-assemble to ribbon-like structure in confined space. GaN surface can have positive or negative polarity depending on whether the surface is Ga- or N-terminated. I studied SAGC in confined space between two electrodes. The current-voltage characteristics can be explained very well with the theory of metal-semiconductor-metal (MSM) structure. I-V curves also show strong rectification effect, which can be explained by the intrinsic polarization along the axis of ribbon-like structure of SAGC. GaN substrate property influences the properties of SAGC. So SAGC has semiconductor properties within the confined space up to 458nm. When the gap distance gets up to 484nm, the structure with guanosine shows resistance characteristics. The photocurrent measurements show that the bandgap of SAGC is about 3.3-3.4eV and affected by substrate properties. The MSM structure based on SAGC can be used as photodetector in UV region. Then I show that the periodic structure based on GaN and SAGC can have photonic …

Transformational leadership describes a leader who motivates followers to performance beyond expectations, but it has often been attacked for its potential to be abused. A newer form of leadership has been proposed, that of authentic leadership. Authentic leadership is an over-arching concept that proposes to include transformational leadership and all positive forms of leadership. At the heart of authentic leadership is the concept of ethicality. The concept of authenticity may contribute to the transformational leadership paradigm, producing an ideal form of leadership. Authentic leadership may not be an over-arching form of leadership, but one suited particularly to transformational leadership. I propose that authentic transformational leadership resides in leaders' and followers' implicit leadership theories. This experiment addresses authentic transformational leadership and the role of implicit leadership theories in directing leader behavior. A model is developed that outlines the relationship between authentic transformational leadership and implicit leadership theories, including the separate implicit theories of leader and follower, leader-member exchange (LMX), and leader effectiveness. Hypotheses concerning these relationships are developed. The study is experimental, using WebCT as a delivery tool. Scenario-based surveys were developed to collect data, using both known measures and measures developed specifically for this experiment. Two pilot studies were conducted …

This study identified the types of sexist language that appear in ESL textbooks by Thai authors. The study analyzed the ESL textbooks by Thai authors sold at the Chulalongkorn University bookstore during spring 2007. It was a qualitative case analysis of fifteen ESL textbooks covering the beginning, intermediate, and advanced levels of ESL instruction. The study used feminist criticism to discover what gender roles are sanctioned as appropriate in ESL textbooks by Thai authors and if the language used supports or challenges patriarchy. The results of this study show that sexist language is present in the textbooks and that the textbooks contain content that promotes sexist assumptions concerning gender roles. As a whole, the language and examples used in ESL textbooks by Thai authors support patriarchy.

Experts in traumatology have postulated traumatized children play differently than non-traumatized children. These differences are called posttraumatic play and include the behaviors of intense play, repetitive play, play disruption, avoidant play and negative affect. The purpose of this study is the continued development of the Trauma Play Scale through the addition of a normative sample. The Trauma Play Scale is an observation-based instrument designed to distinguish the play behaviors of children in play therapy with a history of interpersonal trauma when compared to non-traumatized children. The present study compares two samples of children. One group (n=6) currently in play therapy with a history of interpersonal trauma and another group (n=7) considered normally developing (cognitively, emotionally, socially, and physically) by their parents with no known history of interpersonal trauma. Trained raters blind to the trauma history of the children rated a series of eight consecutive video-recorded play therapy sessions for each participant. One-way analysis of variance statistics, including effect sizes were compute to determine the discriminant validity of the Trauma Play Scale. Traumatized children scored significantly higher on the Trauma Play Scale than non-traumatized children on all domains of the scale as well as the overall Average Trauma Play Scale score. …

Both interpersonal dependency and the importance of the therapeutic alliance to successful psychotherapy outcomes have been widely studied. However, these two areas of study rarely have been viewed conjointly despite the reportedly large number of clients with dependency who present for treatment. This study elucidated the relationship between interpersonal dependency and the therapeutic alliance. Additional hypotheses explored client-therapist agreement on alliance strength in relation to client interpersonal dependency. Participants were graduate student therapists (N = 26) and their individual psychotherapy clients (N = 40) in a training clinic at a large, southwestern university. Within their first three sessions of psychotherapy, participating clients told nine Thematic Apperception Test stories and completed structured self-report measures of adult attachment, social desirability, and psychological symptoms. Interpersonal dependency was scored from the TAT stories, using the TAT Oral Dependency (TOD) scoring system developed by Masling, Rabie, and Blondheim (1967) and Huprich (2008). Three sessions following initial data collection, participating clients and their therapists completed structured self-report measures of the therapeutic alliance. Analyses revealed that interpersonal dependency was not significantly associated with client and therapist alliance ratings or the congruence between client and therapist alliance ratings. However, specific scoring categories of the TOD were associated with …

As the leading cause of death in the United States, coronary heart disease (CHD) is a growing public health problem, despite the fact that many risk factors for the disease are preventable, especially if addressed early in life. The purpose of the current study was to examine the effects of loss-framed versus gain-framed versus information-only health messages on both intention to attend and actual attendance at an appointment to get screened for CHD risk factors (i.e., hypertension, diabetes, and dyslipidemia). It was hypothesized that a population of young adults would be more likely to view screening for CHD risk factors as a low-risk, health-affirming behavior as opposed to a risky, illness-detecting behavior and would thus be more strongly influenced by gain-framed messages than loss-framed messages. Additional goals included the exploration of the extensively researched individual health beliefs of perceived threat (as defined by the health belief model) and health locus of control as they relate to message frames. One hundred forty-three undergraduate students were randomly assigned to either the loss-framed, gain-framed, or information-only control conditions. Framing manipulation checks revealed that participants failed to discern differences in the tone and emphasis of the experimental pamphlets. As a result, no tests of …

In 1988, Jean Guillou composed Hyperion on a commission from the French oil company, Société Nationale Elf Aquitaine, to celebrate its discovery of oil. He developed this theme of fire using his imagination, European philosophical concepts, and various myths. As with Messiaen, rhythm becomes a significant element in Guillou's organ music to convey a heightened dramatic story of an exaltation of fire and to represent the fourth movement of "Agni-Ignis." For aspects of rhythmic structure, I developed new methodology to analyze rhythm in six sections of "Agni-Ignis." Guillou uses experimental rhythmic techniques such as rhythmic subdivision, cycling, rhythmic ostinato, durational contrast, and rhythmic crescendo to build the musical structure of the piece. Among them, the primary subdivision of 16th-note groups organizes throughout the piece as a cyclic theme to convey the powerful and vivid mood of fire. This rhythmic group creates many pitch patterns as thematic transformation to provide both rhythmic and harmonic complexities. The two types of rhythmic ostinato, which is variable and invariable type, juxtapose below the manual's skillful rhythm to provide variety and unity. The other notable features of rhythm appear at the border of each section, such as rhythmic crescendo, durational contrast, 32nd-note groupings, rest and …

Inquiry about ideal library was sought by interdisciplinary approach from human competence derived from performance engineering by Gilbert (1978), and the library information policy by Wilson (1977). With Wilson's insights into the field of library and information science (LIS), this work demonstrated the synthesis of Wilson and Gilbert: engineering as common ground. One of the central concerns in LIS, utilization of knowledge, is re-conceptualized as Gilbert's view of performance, which reflected at different vantage points. Four leisurely theorems are introduced for his view of performance engineering, which produce human competence. The performance matrix is the application tool that represents Gilbert's theorems of performance engineering. It is used to clarify vantage points about the library, and constructed a model of the performance engineering system of ideal library. Based upon the model, two applications were made. One is to apply the performance matrix to the existing academic library. Another is to apply the performance matrix for building a special collection. These two applications show that the performance matrix is capable to analyze existing performance system as well as designing and building a performance system.

Although the mu rhythm is traditionally defined as a normal EEG variant, recent evidence suggests that mu may have functional significance in a variety of disorders such as autism, Parkinson's disease, and multiple sclerosis. While an increasing number of articles have focused on the blocking mechanism of mu in relation to various cognitive processes and disorders, few have examined the significance of a prominent mu rhythm in the background EEG. A few studies have examined the relationship between the mu rhythm and psychological disturbance, such as attentional and affective disorders. Increasing evidence suggests that EEG and qEEG variables may be useful in classifying psychiatric disorders, presenting a neurophysiological alternative to traditional symptom-based diagnosis and classification. Thus, the intention of the present study was to examine the relationship between neuropsychological variables, gathered from multiple assessment sources, and the presence of a prominent mu rhythm in the EEG. Results did not show a statistically significant difference between individuals with and without a prominent mu rhythm on the Test of Variables of Attention (TOVA); although individuals in the mu group showed a pattern of increased impulsivity and performance decrement over time. For adults, no significant differences were observed between groups on psychological variables …
