Michael Nyman: The Man Who Mistook His Wife for a Hat (open access)

Michael Nyman: The Man Who Mistook His Wife for a Hat

Composer Michael Nyman wrote the one-act, minimalist opera The Man Who Mistook His Wife for a Hat, based off the neurological case study written by Oliver Sacks under the same title. The opera is about a professional singer and professor whom suffers from visual agnosia. In chapter 1, the plot and history of the opera are discussed. Chapter 2 places The Man Who Mistook His Wife for a Hat alongside a selection of minimalist operas from Philip Glass and John Adams. Chapter 3 contains a history of the Fluxus art movement and shows where Fluxus-like examples appear in the opera. Chapter 4 includes Nyman's usage of minimalism, vocal congruencies, and Robert Schumann as musical elements that convey the drama.

Street Chords and the Truth: A Street Level View of Country Music (open access)

Street Chords and the Truth: A Street Level View of Country Music

Singers and songwriters come to Nashville, Tennessee because they consider it the center of the country music universe and the best place to perform their songs as they try and break into the music business. Though few ever experience success in this competitive field, artists continue to arrive in Nashville and many don't have the commercial potential that would allow them the opportunity to perform anywhere but on the city's streets. The film, Street Chords and the Truth: A Street Level View of Country Music, focuses on these interesting performers and their music. Country music has been examined by a handful of ethnomusicologists and is often called the music of everyday life. Many recognize its dependence on ordinary singing styles, common phrasings, southern accents and traditional costuming as central to its identity and critical source of its value as a commodity. While many studies have been conducted focusing commercially popular country music singers and the music industry, few studies been conducted on singers who meet all the critical criteria for country music except commercial viability. This documentary examines country music more as a critical element of cultural identity and less as a commodity.

Interpersonal Decentering and Psychopathology in a University Clinic Sample (open access)

Interpersonal Decentering and Psychopathology in a University Clinic Sample

This study examined the relationship between interpersonal decentering and symptoms of psychopathology among 48 clients from the Psychology Clinic at the University of North Texas. The Thematic Apperception Test (TAT) and the Symptom Checklist 90-Revised (SCL-90-R®) instrument were administered to clients along with demographic packets. Interpersonal decentering was assessed using Melvin Feffer's Interpersonal Decentering Scoring System for the TAT. It was hypothesized that higher scores of global symptom severity would be associated with lower scores of interpersonal decentering. Higher scores of paranoid ideation, psychoticism, and hostility were also hypothesized to be associated with lower scores of interpersonal decentering. Results did not support these hypotheses. However, exploratory analyses revealed a significant correlation between higher scores of phobic anxiety and lower scores of interpersonal decentering. Results also provided information regarding the three methods for calculating interpersonal decentering summary scores.

Taking Steps toward Recidivism Prevention: Examining the Impact of Cognitive Behavioral Therapy on Juvenile Delinquency (open access)

Taking Steps toward Recidivism Prevention: Examining the Impact of Cognitive Behavioral Therapy on Juvenile Delinquency

Researchers within the criminal justice field have examined recidivism to discover effective methods to deter criminals from re-offending. Typically, incarceration provided specific deterrence for offenders but recidivism after release proved problematic. Using secondary data analysis, the present study evaluates a cognitive behavioral therapy [CBT] program, Reasoning and Rehabilitation, which the state of Colorado implemented in 1995 among juveniles on intensive probation. The original research team collected the data through pre- and post-questionnaires and interviews with probation officers. The pre- and post-test data are utilized to specifically analyze certain variables including self-control, empathy and problemsolving abilities. The focus of the present study is to determine the level of change in these particular variables as an outcome of completing the CBT program. This analysis also explores the value of CBT programs and examines how the programs alter an offender's level of selfcontrol, empathy and problem-solving abilities thus reducing recidivism after completion.

Minimum levels of physical activity and perceived quality of life. (open access)

Minimum levels of physical activity and perceived quality of life.

The purpose of this study was to examine the association between engaging in minimum levels of physical activity as defined by ACSM and perceived quality of life. A total of 43 college students were included in a repeated measures, quasi-experimental design research study that produced an overall retention rate of 65%, which resulted in 15 students being placed in the treatment group, and 28 students being placed in the control group. Analysis of variance with repeated measures was used to compare the quality of life mean scores over three administrations of the Quality of Life Inventory (QOLI), which resulted in no significant main effects for either the time measure or the group measure, but did produce a significant interaction effect. Post hoc analyses showed there was a significant difference between the treatment and control groups' quality of life mean scores only during the second administration of the instrument. Further analysis showed that the control group had significantly higher quality of life domain scores for six of the 16 quality of life domains. There were no significant differences between groups across any of the physiological measures. These findings did not support previous research that increasing individuals' level of physical activity will …

Immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food. (open access)

Immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food.

The immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food were investigated. A functional analysis indicated that the participant's problem behavior was maintained by tangible (food) reinforcement. In a subsequent analysis, each occurrence of problem behavior produced a bite of wafer in the first and third components of mixed and multiple schedules, while either response-independent food or extinction was presented in the second component. Dense and lean schedules of food delivery were assessed. Results indicated that a very dense schedule of food nearly eliminated problem behavior, a very lean schedule of food and extinction produced substantial decreases in problem behavior, and intermediate schedules did not decrease problem behavior. Response patterns were differentiated across mixed and multiple schedule arrangements, with signaled changes in the schedules (multiple schedule) generally showing more immediate and sustained effects throughout the intervention component. Implications for interpretations of the effects of the intervention are discussed.

Longitudinal Study of Loneliness and Depression as Predictors of Health in Mid- to Later Life (open access)

Longitudinal Study of Loneliness and Depression as Predictors of Health in Mid- to Later Life

The longitudinal relationship between loneliness and depression as predictors of chronic health conditions in middle-aged to older adults was investigated utilizing data collected by the Health and Retirement Study (HRS), a national representative longitudinal study of health, retirement, and aging, conducted by the Institute for Social Research (ISR) Survey Research Center (SRC) at the University of Michigan, funded by the National Institute on Aging and the Social Security Administration. The correlation between these loneliness and depression was moderate (r = .32 to r = 51). The single-item subjective self-report of loneliness was found to be an adequate measure of loneliness. A cross-lagged panel correlation and regression design was used to examine the longitudinal relationship between loneliness, depression, and chronic health conditions. A temporal precedence was indicated implying a causal relationship with depression leading to subsequent loneliness. The relationship between recurring loneliness and chronic health conditions was weak (r = .13).

What Went Wrong?  How Arrogant Ignorance and Cultural Misconceptions Turned Deadly at the San Antonio Courthouse, March 19, 1840 (open access)

What Went Wrong? How Arrogant Ignorance and Cultural Misconceptions Turned Deadly at the San Antonio Courthouse, March 19, 1840

Although the Council House Fight is well written about in the annals of early Texas history, this all-encompassing study will reveal a whole new picture. Unlike previous works that maintained one point of view, multiple perspectives were analyzed and explored to allow a more comprehensive view of the Council House Fight to emerge. Primary focus on social and cultural misunderstandings, as well as the mounting hostility between the Penateka Comanche and Texians across the frontier, will demonstrate their general distrust and hatred of the other. Detailing their complicated relationship will prove that neither the Texians nor the Comanche were without blame, and both shared responsibility for the deterioration of events on and before March 19, 1840.

A Matter of Due Process: An Examination of How State Mandated Accreditation has Impacted Texas Crime Laboratories (open access)

A Matter of Due Process: An Examination of How State Mandated Accreditation has Impacted Texas Crime Laboratories

Mandated accreditation of crime laboratories is a fairly new phenomenon. The state of Texas was the first to require that crime laboratories be accredited in order to be able to present evidence in a criminal proceeding. The laws that govern this are Texas House Bill 2703 and Texas House Bill 1068. The goal of this study is see how the enactment of these laws impacted crime laboratories. There are 42 crime laboratories that are accredited in the state of Texas. This study was conducted by the use of telephone survey interviews. Results indicated that mandated accreditation is a step in the right direction to ensure that objectivity is maintained during the processing and evaluation of physical evidence.

Measuring indices of happiness in a parent-training program. (open access)

Measuring indices of happiness in a parent-training program.

Behavior analysts have long recognized the need for direct and reliable measurement of complex behaviors that are important to society. Recently investigators have approached one of the singular most complex behaviors: happiness. Limited research, however, has explored happiness in parent-training programs with children with autism and their families. The current study applied the definitions and data systems used in Broome's 2007 study to obtain indices of happiness within a parent training program for parents of toddlers with autism. Direct measures of smiles and laughs were collected from videotaped assessments. Results suggest that the program increased behaviors associated with happiness. Results are discussed in terms of program development and future research.

Just Intonation and the Revitalization of Neoclassicism: Three Works for Baroque Instruments (open access)

Just Intonation and the Revitalization of Neoclassicism: Three Works for Baroque Instruments

For a composer of today, the relationship between new music and music from many centuries past remains problematic. In order to create something new, it is necessary to go beyond previous techniques of composition in some way. At the same time, new music that has no connection with music of the past runs the risk of irrelevance. Just tuning offers one possibility for reconciling this problem. By effectively warping music of the past through the lens of altered tuning and contemporary composition techniques, music of the past may be understood in previously unknown ways. Part I, the critical essay, presents historical background and analysis of a cycle of three works in altered/just tuning. Part II presents scores of the works.

Paradox and Balance in the Anglo-Saxon Mind of Beowulf (open access)

Paradox and Balance in the Anglo-Saxon Mind of Beowulf

This essay argues that the Anglo-Saxon poet of Beowulf presents the reader with a series of paradoxes and attempts to find a balance within these paradoxes. At the forefront is the paradox of past and present, explored through the influence of the past on the characters in the poem as well as the poet. Additionally, the poem offers the paradox of light and dark, which ultimately suggests light and dark as symbols of Christianity and paganism. Finally, the land and the sea offer the third primary paradox, indicating the relationship that the characters and poet had with land and sea, while also reflecting the other paradoxes in the poem. The result is the desire to find balance within the paradoxes through the recognition of ongoing tension.

An Analysis of Gay/Lesbian Instructor Identity in the Classroom (open access)

An Analysis of Gay/Lesbian Instructor Identity in the Classroom

In this project I explore the connection between cultural and personal identity in the college classroom. Respondent interviews were conducted using open-ended questions, which began with a broad picture of the role the instructor played in the classroom and then focused more specifically on the issue of sexual orientation and the choices to disclose or not disclose orientation in the classroom. Thematic analysis was used to examine the interviews, upon the completion of the interviews being transcribed. RQ1: Do gay and lesbian instructors disclose their sexual orientation in the classroom? From this question, four themes emerged. These themes were disclosure not relevant, out of the classroom disclosure, students just know, and disclosure in the classroom. RQ2: What reasons do gay and lesbian instructors give for disclosing their sexual orientation in the classroom? Two themes, fears of disclosure and holding back, transpired from this question. RQ3: How do gay and lesbian instructors foster diversity in the classroom related to sexual orientation? Four themes were exposed from the question, and these themes were paradox of diversity, passing, mentoring, and identity not sexuality.

The emergence of joint attention in a naturalistic parent training program. (open access)

The emergence of joint attention in a naturalistic parent training program.

Behaviors related to joint attention have been described by behavior analysts and developmental psychologists alike as having a distinctly social function. Children with autism often do not emit these behaviors. Research on the collateral effects of teaching joint attention suggests far reaching consequences. Given the reported benefits of using these behaviors, and the theoretical descriptions of their function, we assessed joint attention as a collateral effect of a naturalistic parent training program. Data suggest that although these behaviors were not directly targeted, they increased in all 3 children. Implications of parent training goals and child intervention targets are discussed in terms of a behavior analysis of joint attention and child development.

Immediate and generalized effects of one component (Stay Close Tool) of a behavioral parenting curriculum. (open access)

Immediate and generalized effects of one component (Stay Close Tool) of a behavioral parenting curriculum.

The Essential Tools for Positive Behavior Change is a behavioral parenting curriculum that is currently being disseminated throughout the state and Florida and is now being utilized in Texas to teach parents who are at risk or are founded of abuse and neglect. Research on the curriculum thus far has focused on large scale outcomes, skill acquisition of caregivers during analog role-play assessments, and scores on a written quiz. Little research has focused on generalization of classroom performance to the home. The measurement systems that have been used to evaluate positive outcomes also were in need of improvement. The current study was designed to determine whether teaching a component (Stay Close) to typical parents resulted in immediate improvements in written exam scores and on a role-play assessment and if those skills could be seen in a home setting. The results indicated that small improvements were seen across quiz scores in all but one family and some improvements across behavior was seen in both the role-play and home observations. Additionally, a reliable measurement system was created that captured both home observations and role-play assessment data.

The Effects of a "Responsive Teaching Strategy" to Increase Toy Play in Young Children with Autism in an Inclusive Setting. (open access)

The Effects of a "Responsive Teaching Strategy" to Increase Toy Play in Young Children with Autism in an Inclusive Setting.

Toy play represents one of many levels of play where children can expand their repertoires and socially interact with peers. Play typically increases in complexity as the child's repertoire develops; however, children with autism often have delayed play skills. The current study investigated the effects of using a 3-component play training procedure (choices, prompting, and consequences), replicated from a previous study, to increase simple and pretend toy play in three boys with autism. Additional measures were used to observe engagement with materials, children, and adults during a 10-minute session. Observations show increased toy play for two participants and increases in overall engagement for all participants. The findings suggest that the teaching program used is replicable across multiple populations, furthering the advancement of evidence-based practices.

Extermination Warfare? The Conduct of the Second Marine Division at Saipan (open access)

Extermination Warfare? The Conduct of the Second Marine Division at Saipan

Historians John W. Dower, Craig Cameron, and Ronald Takaki argue that the Pacific War was a war of extermination fueled by race hate. Therefore, the clash between the military forces of the Japanese Empire and United States of America yielded a "kill or be killed" environment across the battlefields of the Pacific. This work examines the conduct of the Second Marine Division during its campaign of conquest against the Japanese held island of Saipan from June 15, 1944-July 9, 1944. It is based upon traditional military history sources to test their theories in context of the conduct of Marines toward Japanese soldiers and civilians during the Saipan campaign. Did Marines practice a war of extermination or conduct themselves in a humane manner?

Slaveholders and Slaves of Hempstead County, Arkansas (open access)

Slaveholders and Slaves of Hempstead County, Arkansas

A largely quantitative view of the institution of slavery in Hempstead County, Arkansas, this work does not describe the everyday lives of slaveholders and slaves. Chapters examine the origins, expansion, economics, and demise of slavery in the county. Slavery was established as an important institution in Hempstead County at an early date. The institution grew and expanded quickly as slaveholders moved into the area and focused the economy on cotton production. Slavery as an economic institution was profitable to masters, but it may have detracted from the overall economic development of the county. Hempstead County slaveholders sought to protect their slave property by supporting the Confederacy and housing Arkansas's Confederate government through the last half of the war.

Models to Combat Email Spam Botnets and Unwanted Phone Calls (open access)

Models to Combat Email Spam Botnets and Unwanted Phone Calls

With the amount of email spam received these days it is hard to imagine that spammers act individually. Nowadays, most of the spam emails have been sent from a collection of compromised machines controlled by some spammers. These compromised computers are often called bots, using which the spammers can send massive volume of spam within a short period of time. The motivation of this work is to understand and analyze the behavior of spammers through a large collection of spam mails. My research examined a the data set collected over a 2.5-year period and developed an algorithm which would give the botnet features and then classify them into various groups. Principal component analysis was used to study the association patterns of group of spammers and the individual behavior of a spammer in a given domain. This is based on the features which capture maximum variance of information we have clustered. Presence information is a growing tool towards more efficient communication and providing new services and features within a business setting and much more. The main contribution in my thesis is to propose the willingness estimator that can estimate the callee's willingness without his/her involvement, the model estimates willingness level based …

General Nathan F. Twining distinguished himself in leading the American Fifteenth Air Force during the last full year of World War II in the European Theatre. Drawing on the leadership qualities he had already shown in combat in the Pacific Theatre, he was the only USAAF leader who commanded three separate air forces during World War II. His command of the Fifteenth Air Force gave him his biggest, longest lasting, and most challenging experience of the war, which would be the foundation for the reputation that eventually would win him appointment to the nation's highest military post as Chairman of the Joint Chiefs of Staff during the Cold War.

Use of In-Stream Water Quality Measurements and Geospatial Parameters to Predict Consumer Surfactant Toxic Units in the Upper Trinity River Watershed, Texas (open access)

Use of In-Stream Water Quality Measurements and Geospatial Parameters to Predict Consumer Surfactant Toxic Units in the Upper Trinity River Watershed, Texas

Surfactants are used in a wide assortment of "down-the-drain" consumer products, yet they are often discharged in wastewater treatment plant effluent into receiving water, potentially causing environmental harm. The objective of this project was to predict surfactant toxic units and in-stream nutrients in the upper Trinity River watershed. Surface and pore water samples were collected in late summer 2005. General chemistries and surfactant toxic units were calculated. GIS models of anthropogenic and natural factors were collected and analyzed according to subwatersheds. Multiple regression analyses using the Maximum R2 improvement method were performed to predict surfactant toxic units and in-stream nutrients using GIS and in-stream values. Both geospatial and in-stream parameters generated multiple regression models for surfactant surface and pore water toxic units, as well as in-stream nutrients, with high R2 values. Thus, GIS and in-stream parameter modeling have the potential to be reliable and inexpensive method of predicting surfactant toxic units and nutrient loading in the upper Trinity River watershed.

Milk machines: Exploring the breastfeeding apparatus.

Arguing that current discourse surrounding breastfeeding and the lactating body promotes management of the female body, I attempt to devise an explanation of the breastfeeding apparatus and its strategies. In this study, the strategies include visual and linguistic representations of breastfeeding through art, promotional materials for advertisement and recommendations from the medical community, and the language used in the legal protection of breastfeeding. Using a rhetorical lens, I explore how these varied junctions operate within the breastfeeding apparatus and how breastfeeding is both a product of and a product in the technology. I seek to find what else is at work and how breastfeeding functions as a discursive element in its own right, allowing it to function as an apparatus for control. Finally, I question the potential for resistance in breastfeeding, asking if the lactating body has options, or is the subject so policed and managed that decisions are dictated by the breastfeeding apparatus.
