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.

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 …

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.

Multi-rater tools also referred to as 360-degree feedback tools, are frequently used in addition to traditional supervisory appraisals due to sources (i.e., supervisor, peer, direct report) unique perspectives and opportunities to view different aspects of job performance. Research has found that the differences among sources are most prevalent between self and other ratings, and the direction of agreement is related to overall job performance. Research has typically focused on one form of agreement, the direction of an individual's self-ratings compared to others' ratings. The current study expanded on past research on rater agreement using a data set (n = 215) consisting of multi-rater data for professionals participating in a leadership development process. The study examined the ability to predict job performance with three different measures of self-other agreement (i.e., difference between overall mean scores (difference), mean absolute difference across items (difference), and mean correlation across items (similarity)). The study also examined how the relationships may differ across performance dimensions. The final purpose was to explore how the importance of the performance dimensions, as rated by the participant, may moderate the relationship between self-other agreement and job performance. Partial support for study's hypotheses was found. The direction and difference measures of …

The influence of the role identity expectations of Turkish Hizbullah's leadership on actual members' terrorist identities was documented in this dissertation. This study explored the leadership's identity expectations from members through content analyses of four books written by major figures of Hizbullah. Those books were selected following comments of the literature and expert suggestions. Eleven identity features stood out. These content analyses also revealed that leadership had different expectations from political wing members and military wing members. The following six identity features were listed as expected more from military wing members: belief in jihad and resistance, desire for martyrdom, embracing the hierarchical structure, depersonalization, hatred against enemies of God, and aloneness. Whilst cemaat (religious congregation), being religiously educated, patience (gradualism), dedication to a Muslim brotherhood, and being politically active were listed as expected identity attributes of political wing members. Qualitative analyses investigated these identity features using the available literature and 144 handwritten reports of actual Hizbullah members. To confirm the findings of content and qualitative analyses, quantitative analyses were conducted on the relatively representative sample (144 reports). The results of cross-tabulation and logistic regression demonstrated that two (out of 6) military wing and two (out of 5) political wing identity …

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.

Ellen Taaffe Zwilich is an important figure in the compositional world, having written a diverse body of works for which she has received many accolades, including the coveted Pulitzer Prize. The second chapter examines this American composer, the commission of the American Concerto, and events leading to the piano reduction of the concerto. The America Concerto is a modern work that incorporates synthetic scales, unusual notation, and the organization of melodic material through motives. The third chapter includes an analysis that identifies the form and tonal centers as well as the primary motives used in the concerto. The fourth chapter includes pedagogy considerations for performance. Issues relating to tessitura, articulation, flexibility, endurance factors, fingerings, and technical features of the piano reduction accompaniment are evaluated. Detailed suggestions are provided to aid in preparing the piece for performance, including a study of stylistic concerns. The American Concerto is quite diverse stylistically as Zwilich explores the symphonic and jazz genres. The dual nature of the trumpet is examined as the piece combines classical and jazz styles in a virtuosic setting.

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 …

Dementia is prevalent among elderly people. As the world population ages, it is projected that the number of people affected by dementia may triple in the next 50 years. Over the last two decades, research has focused on identifying potentially modifiable risk factors in development and progression of dementia, such as vitamin B12 and folate. Results concerning the effects of low folate and vitamin B12 on cognitive performance are mixed. The main objective of the present study was to investigate the effects of vitamin deficiency on cognitive functioning in a clinical sample of elderly individuals with cognitive problems using a comprehensive neuropsychological assessment. A retrospective chart-review was performed on the 102 records of patients from the Geriatrics Clinic at the University of North Texas Health Science Center who presented with cognitive deficits. Charts were reviewed to obtain data on vitamin supplementation, vitamin status, history of chronic conditions and other biochemical data. The available database was used to obtain data on neuropsychological assessment. The study demonstrated mild association between vitamin B12 and folate status and cognitive deficits. There appeared to be a higher cut-off level that is above the traditionally used levels for vitamin B12 and folate deficiency concentrations at which …

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 …

The 1994 publication of a new version of Carl Orff's Carmina Burana, arranged for winds, percussion and choruses by Juan Vicente Mas Quiles, created new possibilities for the performance of Orff's monumental work. This dissertation serves as a guide to the study and performance of the Mas Quiles arrangement of Carmina Burana. Chapter One presents a brief discussion of Carl Orff and his Carmina Burana, followed in Chapter two by a short discussion of Mas Quiles' and the other significant transcriptions and arrangements of Carmina Burana, Chapter three contains a review of the literature pertinent to the study Carmina Burana. In Chapter Four a detailed examination and comparison of the original Orff score with the Mas Quiles arrangement provides a framework with which the conductor may study and compare the two scores in preparation for a performance of the Mas Quiles arrangement. The scoring of the Mas Quiles arrangement is masterful in that the arrangement so closely maintains the textural, musical and aesthetic integrity of the work. The Mas Quiles version includes all of the movements, and all of the original elements: choruses, soloists and orchestral parts are preserved intact. The only substantive change is the judicious use of winds …

The connection of music and verse evident in the work of American poet, Carl Sandburg, is a topic that has received inadequate attention. Much preexisting research has focused on Sandburg's work with The American Songbag anthology; however little has been written about music composers' settings of his verse. The relevance of Sandburg's work as a poet has faded in today's society; the rural prairie subject matter and his poetic style are deemed archaic in an ever-evolving mechanistic society. Philip Wharton, a native of Sandburg's Midwest prairie, composes to create an evocative and image-laden world for the hearers of his music. This is what creates a semblance between both artists' works. This paper makes a connection between the work of the 20th century prairie poet and a current, 21st century American composer's musical setting of Sandburg's verse. Both artists are connected not only geographically, but also in their approach to an accessible art form for their audience. Negating current compositional trends and using text from Sandburg's poetry collections, Chicago Poems and Cornhuskers, Wharton melds the text into his evocative, imagistic musical language in his song cycle, The Prairie Sings. Using examples from the five movements of the cycle, I show the …

This study evaluates archival data from a home intervention with an at-risk preschool child and her family. The intervention model studied was created by the Developmental Research Lab at Texas Christian University. Data was collected prior to and during the first 4 weeks of intervention to assess change in parent-child interaction, behavior and neurochemical profile. Measures used include coding of videotape recordings of the intervention, neurotransmitter levels taken via subject urine samples, Child Behavior Checklist, Parent Stress Index, and ACTeRS Parent Form. Results suggest positive change in parent-child interaction, behavior and neurochemical profile. However, consistent growth was not observed in several neurochemical results. Future studies should assess the entirety of the home intervention model and with a larger sample size.

The five countries that lie on the isthmus connecting North and South America have endured a past of colonialism, civil war, and natural disaster. As these countries evolve in the 21st century, growing economies and political peace provide a promising outlook for the citizens of these nations. The media industries in these nations have varying levels of development which are explored in this thesis. Using Michael Porter's 1990 framework and a case study methodology, this thesis explores the differences and similarities of media industries in Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica, and what may be done to ensure future success in an increasingly global world.

Numerous models of IS success and technology acceptance their extensions have been proposed and applied in empirical. This study continues this tradition and extends the body of knowledge on the topic of IS success by developing a more comprehensive model for measuring IS success and technology acceptance within a government organization. The proposed model builds upon three established IS success and technology acceptance frameworks namely the DeLone and McLean (2003), Venkatesh et al.'s (2003) unified theory of acceptance and use of technology (UTAUT), and Wixom and Todd (2005). The findings from this study provide not only a comprehensive IS success assessment model but also insights into whether and how IS success models are influenced by application variables as applied within a government organization. Exploratory factor analysis and confirmatory factor analysis were performed for instrument refinement and validity test of the existing and proposed models. Using data from employees of a local government municipal, the comprehensive model explained 32 percent variance. Four of the hypothesis were fully supported five were not supported, and four were partially supported. In addition, the results suggest that behavioral intention may not be the best predictor of technology acceptance in a mandatory environment.

This thesis examines why some governments and rebel organizations but not others recruit children to be child soldiers. The theory posits that if a country fights in a civil war of long duration, armed groups are more likely to recruit children as soldiers. I find that the probability of child soldier recruitment increases when a country experiences following conditions: a longer duration of civil war, a large proportion of battle deaths, a large number of refugees, a high infant mortality rate, and the presence of alluvial diamonds. An increase in education expenditures and civil liberties would decrease the probability of child soldier recruitments.

The purpose of this study was to examine the effects of teenage motherhood on the school readiness, literacy skills, and parental involvement of children participating in the Home Instruction for Parents of Preschool Youngsters (HIPPY) early intervention program, as well as make recommendations for optimal outcomes. Study children were participants in HIPPY at five diverse, urban school districts. Using a mixed method design, this study examined the results of quantitative measures of children's school readiness, literacy skills, and parent involvement along with qualitative data collected through mothers' responses to two, open-ended questions related to their satisfaction with HIPPY. According to results of independent samples t-test, mean scores on school readiness and parent involvement measures were not statistically significantly different for the children of teenage mothers and the children of traditional age mothers. However, there were moderate effect sizes for parent involvement and physical development indicating some practical significance. Chi-square results of literacy skills indicated that the children of teenage mothers were almost twice as likely [c2 (1, N = 36) = 4.21, p < .05] to have literacy skills that were "not on grade level" according to scores on the TPRI/Tejas. Descriptive discriminant analysis (DDA) indicated that the multivariate relationship …

The current study consisted of two experiments, both of which were comparisons of choice conditions replicated across four participants. Four typically-developing pre-school children participated in this study. Experiment 1 evaluated participants' preference for choosing consequent stimuli prior to engaging in academic tasks (pre-session choice) versus choosing consequent stimuli each time criterion for reinforcement had been met within the session (within-session choice). In Experiment 2, preference for choice-making was evaluated when outcomes for both choice and no-choice conditions were identical. For two participants, results indicated strong preference for choice-making.

Resonant singing creates possibilities with dynamic shading, subtlety of phrasing, and rich vibrant tone that astonishes listeners. Choral singing that employs resonance as a fundamental ensemble virtue yields impressive results that lend themselves well to the varying demands of any choral score. Fortunately, choruses of every level can benefit from an increased understanding of the basic principles of resonance in the singing voice. Research on issues of upper partial energy and the presence of the singer's formant in a choral ensemble has been limited in approach. Many published studies regarding upper partial energy in the choral ensemble are based on what the ensemble is already doing, which is linked to the teaching of that specific director and that specific choir. Research must include a wider range of aesthetic choices with regard to choral unification. Through examining spectrograms that represent the sound of some of the most renowned choirs, it is possible to see that many of these ensembles are producing tone that contains a high level of upper formant energy. Interviews with established conductors reveal approaches and teaching methodologies that reinforce this type of singing. It is possible to teach the individuals in a choir to increase the level of …

In Part I of this thesis, I examine the use of Latin American rituals, ceremonies, and traditional folklore as conceptual and compositional material; studying and re-contextualizing concepts, cultures, and ideologies, and introducing them to foreign audiences. I explore issues such as laptop improvisation, interaction with other performance forces, and the utilization of the social elements of non-western celebrations, as explored in Clestrinye, a work for live and fixed electronics, mixed ensemble, dancers, and painters.

There is a need to understand the relationship between, the traditional 16-week versus an 8-week, and college-level mathematics success rates. This study applied chi-square (χ2) and analysis of variance to compare and contrast which course length of time, 8-weeks or 16-weeks, for college algebra resulted in a higher proportion of students successfully completing the course. In addition, success rates among ethnicities, gender, and age groups were also examined. The population sample for this study was 231 students enrolled in college algebra from fall 2004 through fall 2007. Data was analyzed on four sections of the traditional 16-week courses and four sections of 8-week courses. Success was defined as earning a grade of A, B, or C in the course. The study found that overall there was no significant difference in success rates for the 8-week and 16-week college algebra courses. However, significant differences were found in success rates among Asian, Pacific Islander students enrolled in the 8-week and 16-week courses. No significant differences in success rates were found for White, Non-Hispanic; African-American, and Hispanic, Mexican American students. There was a significant difference in the number of A's, B's, C's, D's and F's among White, Non-Hispanic students, but there was no …

Using the principles of systems analysis as a guide, this study compared two class schedule formats used by Behavior Management and Parenting Services (BMAPS) in order to address the following research questions: 1) What effects do 2 different class formats have on student attrition and appointment keeping? 2) What effects do 2 different class formats have on student outcomes on a pre and posttest assessment? 3) What effects do 2 different class formats have on staff procedures? BMAPS provides parent education to individuals referred by Child Protective Services. The current research included approximately 200 referred clients with an appointment or class scheduled with BMAPS between January 1, 2006 and September 22, 2007. Data was collected by reviewing client files for class attendance and performance records. Results of this study allow BMAPS to enlist the class format that is correlated with better attrition rates and client outcomes.

Density functional (ca, BLYP, BPW91, B3LYP and B3PW91), MP2 and CCSD(T) methods in combination with LANL2DZ or cc-pVxZ-PP (where x=D(double), T(triple) Q(quadruple), and 5(quintuple)) basis sets have been employed in computing electronic transition energies of zinc and cadmium monomers. CCSD(T)/aug-cc-pV5Z-PP combination finds values that are 150 cm-1 from the experimental value for the zinc monomer and 240 cm-1 remove from the cadmium monomer excitation experimental value. These method/basis set combinations are also used to find spectroscopic values (re, De, we, wexe, Be , and Te) that rival experimental values for dimers and excimers. Examples of this can be seen with the CCSD(T)/aug-cc-pV5Z-PP combination phosphorescent emission results. The values found are within 120 cm-1 of the zinc emission energy and 290 cm-1 of the cadmium emission energy. While this combination rigorously models spectroscopic constants for monomers, dimers, and excimers, it does not efficiently model these constants for larger clusters with available modern computational resources. It is important to show spectroscopic trends (bonding, phosphorescent excitation and emissions) as clusters increase as the monomer and dimer emission energies do not model solid state metallophilic interactions and phosphorescence. The MP2/LANL2DZ combinations show qualitative cooperative bonding trends in group oligomers and extended excimers as size …

In this work I present a constructive method for finding critical points of the Ginzburg-Landau energy functional using the method of Sobolev gradients. I give a description of the construction of the Sobolev gradient and obtain convergence results for continuous steepest descent with this gradient. I study the Ginzburg-Landau functional with magnetic field and the Ginzburg-Landau functional without magnetic field. I then present the numerical results I obtained by using steepest descent with the discretized Sobolev gradient.
