Impacts of Comprehensive Climate and Energy Policy Options on the U.S. Economy (open access)

Impacts of Comprehensive Climate and Energy Policy Options on the U.S. Economy

This study compiles and updates the findings of 16 comprehensive state climate action plans and extrapolates the results to the nation. The study then takes those results and using a widely accepted econometric model projects the national impact of these policies on employment, incomes, gross domestic product (GDP) and consumer energy prices. Finally, using the bottom-up data developed by the states and aggregated here, the study models the national impact of major features of the Kerry-Lieberman climate bill under consideration in Congress in 2010. These state action plans and supporting assessments were proposed by over 1,500 stakeholders and technical work group experts appointed by 16 governors and state legislatures to address climate, energy and economic needs through comprehensive, fact-based, consensus-driven, climate action planning processes conducted over the past five years with facilitative and technical assistance by the Center for Climate Strategies. Findings show potential national improvements from implementation of a top set of 23 major sector-based policies and measures drawn from state plans.

Parent Psychopathology, Marital Adjustment, and Child Psychological Dysfunction: The Mediating Role of Attachment and Sibling Relationship (open access)

Parent Psychopathology, Marital Adjustment, and Child Psychological Dysfunction: The Mediating Role of Attachment and Sibling Relationship

This study is part of a larger research project examining family attachment processes. The current study tests a family process model that postulates the mediating role of parent-child attachment and sibling relationship quality in the associations of parent psychopathology or marital adjustment to children's psychological dysfunction. A community sample of 86 families with at least one school-aged (8-12 years) child was recruited from area schools and organizations. Families came to the UNT Family Attachment Lab, where they participated in research tasks, including interviews, self-report instruments, and videotaped interaction tasks. Specific questionnaires used in this study included the Sibling Relationship Questionnaire, the Security Scale, the Behavior Assessment System for Children, the Symptom Assessment-45 Questionnaire, and the Dyadic Adjustment Scale. Using a single indicator for each variable, path analyses tested three paternal models, three maternal models, and three systemic models using different informants' (i.e., father, mother, child) reports of child functioning as the outcome variable. Results of this study highlight the positive relationship between parent marital adjustment and parent-child attachment security, as well as the inverse relationship between maternal psychopathology and mother-child attachment security. In addition, the inverse relationship between parent-child attachment security and child psychological dysfunction was significant across nearly all …

The Instrumental Music of Ida Gotkovsky: Finding Intertextual Meaning (open access)

The Instrumental Music of Ida Gotkovsky: Finding Intertextual Meaning

Ida Gotkovsky, a student of Olivier Messiaen and Nadia Boulanger, composed for nearly every instrument, voice, and ensemble. Although Gotkovsky's Concerto for Trombone is a monumental work for the trombone it is rarely performed and recordings are scarce. There is a general lack of scholarly attention to the music of Ida Gotkovsky, however, the technical and aesthetic quality of her music merits further examination. Previous studies of Gotkovsky's music focused on the analysis of individual compositions. However, much more can be learned by examining a work within the context of her general compositional output. Gotkovsky's compositional style includes extensive musical self-borrowing. The goal of this project is to demonstrate melodic and textural similarities and differences within her music to inform performance practice and to establish interest in her music. The context in which Gotkovsky reuses her music is significant and can provide additional musical insight. An informed awareness of her extensive use of self-quotation familiarizes the performer with her compositional language in a variety of musical settings. Such familiarity with her musical style leads to an improved and artistically educated performance.

Effective and Accelerated Informative Frame Filtering in Colonoscopy Videos Using Graphic Processing Units (open access)

Effective and Accelerated Informative Frame Filtering in Colonoscopy Videos Using Graphic Processing Units

Colonoscopy is an endoscopic technique that allows a physician to inspect the mucosa of the human colon. Previous methods and software solutions to detect informative frames in a colonoscopy video (a process called informative frame filtering or IFF) have been hugely ineffective in (1) covering the proper definition of an informative frame in the broadest sense and (2) striking an optimal balance between accuracy and speed of classification in both real-time and non real-time medical procedures. In my thesis, I propose a more effective method and faster software solutions for IFF which is more effective due to the introduction of a heuristic algorithm (derived from experimental analysis of typical colon features) for classification. It contributed to a 5-10% boost in various performance metrics for IFF. The software modules are faster due to the incorporation of sophisticated parallel-processing oriented coding techniques on modern microprocessors. Two IFF modules were created, one for post-procedure and the other for real-time. Code optimizations through NVIDIA CUDA for GPU processing and/or CPU multi-threading concepts embedded in two significant microprocessor design philosophies (multi-core design and many-core design) resulted a 5-fold acceleration for the post-procedure module and a 40-fold acceleration for the real-time module. Some innovative software modules, …

Information Literacy Skills in the Workplace: A Study of Police Officers (open access)

Information Literacy Skills in the Workplace: A Study of Police Officers

Information literacy has become more important as more information is produced and communication has become easier. Better information skills are vital for individuals working in governmental organizations as well as in the business sector. Employees are expected to be confident and competent in interacting with information in their workplaces in order to deliver better service to customers and to the public. This study examines the differences in information literacy skills (ILS), computer literacy skills (CLS), and frequencies of use of information sources (FIS) among police officers, based on their socio-demographic characteristics, namely education, departmental affiliation, ranks, and experience. Information literacy process models developed in an educational environment are combined to explore information literacy process in the workplace. Bivariate and multivariate analyses indicated significant differences of ILS and CLS based on education, departmental affiliation, and ranks but no difference for experience. In addition, there were differences of FIS for all demographic variables except departmental affiliation. The findings of the study may guide both future researchers in the process of developing new models in understanding information literacy process and the managers in police organizations in planning better training programs by considering information and computer literacy skills and use of information sources of …

Time Series Analysis of Going Private Transactions: Before and after the Sarbanes-Oxley Act (open access)

Time Series Analysis of Going Private Transactions: Before and after the Sarbanes-Oxley Act

Using 1,473 going private transactions completed between 1985 and 2007, I assess whether the increase in going private transactions that occurred after the passage of the Sarbanes-Oxley Act of 2002 (SOX) was driven by SOX, or whether this phenomenon continues an ongoing historical trend. To examine this issue, I initially used structural break tests and intervention analysis. From the initial techniques, I find support that the passage of SOX increased going private transactions for these categories. Secondarily, I use Granger causality tests and impulse response functions to examine the link between going private transactions and the public stock market. When I categorize going private transactions according to the type of acquirer, transaction size, and target industry, I find bi-directional Granger causality relationships between smaller-sized going private transactions and the S&P 500 Index (or Tobin's Q). I also find several unidirectional Granger causality relationships for some categories of going private transactions, based on the type of acquirer or the target industry, to the S&P 500 Index (or to Tobin's Q). The impulse response of going private transactions (or the public stock market) to a shock in the public stock market (or going private transactions) is not immediate, but is delayed two …

An Analysis of the Pedagogical Advantages Relating to Combined Study of Euphonium and Trombone through the Use of Specific Repertoire (open access)

An Analysis of the Pedagogical Advantages Relating to Combined Study of Euphonium and Trombone through the Use of Specific Repertoire

Doubling is defined as playing two instruments. It is becoming increasingly necessary for low brass musicians to double in the course of their careers. Euphoniumists often learn trombone, and trombonists learn euphonium. The instruments share several surface similarities but also differ in many significant ways. Interviews with six professional doublers highlight strategies for learning, teaching, and performing on both trombone and euphonium. Slide and valve technique, adjustment of intonation, tone quality, air usage, repertoire, and skill maintenance are all addressed. Trombone literature comprises a large part of the euphonium repertoire, due to the fact that most trombone pieces can be performed on euphonium. Euphoniumists should avoid playing pieces that require glissandi or extremely loud dynamics to be effective. Euphonium solos are generally too technical to be practical for trombonists to perform. Grøndahl's Concert pour trombone et piano ou orchestre is a standard piece for both instruments. When performing the piece on either instrument, it is helpful to practice the piece on both trombone and euphonium in order to tap into each instrument's strengths.

Non-Linear and Multi-Linear Time in Beethoven's Opus 127: An Analytical Study of the "Krakow" Sketch Materials (open access)

Non-Linear and Multi-Linear Time in Beethoven's Opus 127: An Analytical Study of the "Krakow" Sketch Materials

Beethoven's complex manipulation of formal structures, especially his tendency to build important connections and transformative continuities between non-adjacent sections of musical works, may be seen to function as an attempt to control and sometimes to distort the listener's perception of both the narrative process of musical directionality, as well as the subjective interpretation of time itself. Temporal distortion often lies at the heart of Beethoven's complex contrapuntal language, demonstrated equally through the composer's often enigmatic disruption of phrase-periodic gestures, as well as by occasional instances of overtly incongruous temporal shifts. The "Krakow" collection of compositional sketches for Beethoven's String Quartet in E-Flat, Op. 127, provides a number of instances of "non-linear" or "multi-linear" musical continuity. The term "Krakow" sketches, when referenced in this dissertation, specifically designates the group of Beethoven manuscripts possessed by the Biblioteka Jagiellońska in Krakow, Poland, but which formerly were held by the Royal Library in Berlin. Structural voice-leading analyses are provided for selected portions of the "Krakow" collection; these analyses are then compared to voice-leading graphs and analytical reductions of the corresponding material from Beethoven's published versions of the same musical passages. In some cases the sketches supply almost complete texts, for which critical transcriptions are …

The Avatar by Steve Rouse:  A Performance Practice Guide (open access)

The Avatar by Steve Rouse: A Performance Practice Guide

The Avatar for trumpet and piano by Dr. Steve Rouse is one of the most challenging compositions in the trumpet repertoire. Due to The Avatar's challenges and increasing popularity, a study is necessary to aid its performance. Each movement is performed on a different instrument: Bb piccolo (with an optional A piccolo part) for Nativity, Bb Flugelhorn for Enigma-Release and Bb trumpet for Rebirth. In addition, the performer must convey one of the work's possible programmatic meanings: (1) The Hindu belief of an Avatar and its life cycle, (2) the life of Christ or (3) the human lifecycle. Chapter 1 gives historical information about the work. Chapters 2-4 discuss each movement of The Avatar programmatically and pedagogically. Facets of each movement are analyzed including differences in programmatic choices, rehearsal techniques and sound concepts. Chapter 5 provides recording suggestions, including choosing a recording engineer, preparing and planning for a recording section, choosing a venue and the benefits of hiring a tonmeister.

Free Radical Induced Oxidation, Reduction and Metallization of NiSi and Ni(Pt)Si Surfaces (open access)

Free Radical Induced Oxidation, Reduction and Metallization of NiSi and Ni(Pt)Si Surfaces

NiSi and Ni(Pt)Si, and of the effects of dissociated ammonia on oxide reduction was carried out under controlled ultrahigh vacuum (UHV) conditions. X-ray photoelectron spectroscopy (XPS) has been used to characterize the evolution of surface composition. Vicinal surfaces on NiSi and Ni(Pt)Si were formed in UHV by a combination of Ar+ sputtering and thermal annealing. Oxidation of these surfaces in the presence of either O+O2 or pure O2 at room temperature results in the initial formation of a SiO2 layer ~ 7 Å thick. Subsequent exposure to O2 yields no further oxidation. Continued exposure to O+O2, however, results in rapid silicon consumption and, at higher exposures, the kinetically-driven oxidation of the transition metal(s), with oxides >35Ǻ thick formed on all samples, without passivation. The addition of Pt retards but does not eliminate oxide growth or Ni oxidation. At higher exposures, in Ni(Pt)Si surface the kinetically-limited oxidation of Pt results in Pt silicate formation. Substrate dopant type has almost no effect on oxidation rate. Reduction of the silicon oxide/metal silicate is carried out by reacting with dissociated NH3 at room temperature. The reduction from dissociated ammonia (NHx+H) on silicon oxide/ metal silicate layer shows selective reduction of the metal oxide/silicate layer, …

Factors Influencing BI Data Collection Strategies: An Empirical Investigation (open access)

Factors Influencing BI Data Collection Strategies: An Empirical Investigation

The purpose of this dissertation is to examine the external factors that influence an organizations' business intelligence (BI) data collection strategy when mediated by BI attributes. In this dissertation, data warehousing strategies are used as the basis on which to frame the exploration of BI data collection strategies. The attributes include BI insightfulness, BI consistency, and the organizational transformation attribute of BI. The research population consisted of IT professionals and top level managers involved in developing and managing BI. Data was collected from a range of industries and organizations within the United States. An online survey was used to collect the data to empirically test the proposed relationships. Data was analyzed using partial least square path modeling (PLS). The results of this study suggest that there exists a positive relationship between institutional isomorphism and BI consistency. The results also indicate that there exists a positive relationship between BI consistency and BI comprehensive data collection strategy, and the organizational transformation attribute of BI and BI comprehensive data collection strategy. These findings provide a theoretical lens to better understand the motivators and the success factors related to collecting the huge amounts of data required for BI. This study also provides managers with …

Paul Hindemith's Septet (1948): A Look Back to Neue Sachlichkeit (open access)

Paul Hindemith's Septet (1948): A Look Back to Neue Sachlichkeit

In the early 1920s, Gustav Friedrich Hartlaub created a fine arts movement that began in Weimar, Germany, which questioned artistic Expressionism. In 1923, he formed an art exhibition to display new art works of simplicity that were of his anti-Expressionist goal. This exhibition was termed Neue Sachlichkeit, or New Objectivity, and quickly became associated with all fine arts. Music of Neue Sachlichkeit ideals during the 1920s and 1930s began to exhibit anti-Expressionist concepts of form, neoclassicism and limited instrumentation. Paul Hindemith was among the leading figures of Neue Sachlichkeit music. Although Paul Hindemith's Septet (1948) was composed during his later career, it shows many Neue Sachlichkeit traits found previously in the 1920s and 1930s. Characteristics of limited/mixed instrumentation, neoclassic instrumentation and form, and Baroque counterpoint are found in the Septet. These traits can also be head in earlier Neue Sachlichkeit pieces by Hindemith such as Hin und zuruck, op. 45a (1927), Das Marienleben (1922/23, rev. 1948) and Neues vom Tage (1929). Chapter 2 examines the Neue Sachlichkeit movement within the fine arts. Chapter 3 gives a brief biography of Paul Hindemith with a concentration on his influence of Neue Sachlichkeit music of the 1920s and 1930s. This chapter also relates …

Faculty Members' Readiness for E-learning in the College of Basic Education in Kuwait (open access)

Faculty Members' Readiness for E-learning in the College of Basic Education in Kuwait

E-learning exposes students and instructors to different learning models such as constructivism rather than the traditional learning. E-learning as a part of today's technology has proven that it is appropriate for most students' mentalities and is a mind tool which promotes different learning models, such as problem solving strategy, collaborative learning, and critical thinking. The Public Authority for Applied Education and Training (PAAET) in Kuwait consists of more than 10 academic colleges with a total number of 120 faculty members. The College of Basic Education (CBE) is one of them. The implementation of e-learning at the College of Basic Education requires that all the learning community members, instructors and students, understand that an e-learning course is like a learning community with the privilege of sharing knowledge, opinions, experiences related to class subject, and productive outcomes that are beneficial to this learning community. This study indentified the statistically significant differences in demographic characteristics of e-learning adopters and non-adopters among faculty members at CBE, examining faculty members' attitudes and skills toward e-learning readiness. The study will explore perceived barriers that face e-learning at CBE. Applying the Rogers diffusion of innovation theory, the influence of 4 factors was examined regarding faculty readiness for …

The Works for Clarinet Commissioned by the Concours International d'Exécution Musicale de Genève: A Critical Survey and Performance Guide (open access)

The Works for Clarinet Commissioned by the Concours International d'Exécution Musicale de Genève: A Critical Survey and Performance Guide

Beginning in 1939, the Concours International d'Exécution Musicale de Genève (CIEM; Geneva International Music Competition) is unique among international music competitions in its multidisciplinary approach. To date, fifteen works have been commissioned for clarinet for the years in which the clarinet was involved. The most well-known of these works is the unaccompanied work by Heinrich Sutermeister, Capriccio for Solo Clarinet in A, written in 1946 for the 1947 competition. This work is a staple in the unaccompanied clarinet repertoire. However, the other fourteen works commissioned for the competition are little known and to date no document has been prepared that examines each of these works in the context of the competition and clarinet literature. While perhaps less notable, works were also commissioned for a sight reading portion of the competition for many of the years in which the clarinet was a discipline chosen for the competition, two of which were published. These works are examined as well. This survey provides a critical, analytical, historical, performance-related and biographical review of the published and unpublished works commissioned for the clarinet by CIEM. The composers, competitors and the significance of these works and winners in the clarinet literature and history are included. A …

Hepatotoxicity of Mercury to Fish (open access)

Hepatotoxicity of Mercury to Fish

Tissue samples from spotted gar (Lepisosteus oculatus) and largemouth bass (Micropterus salmoides) were collected from Caddo Lake. Gar and bass livers were subjected to histological investigation and color analysis. Liver color (as abs at 400 nm) was significantly correlated with total mercury in the liver (r2 = 0.57, p = 0.02) and muscle (r2 = 0.58, p = 0.01) of gar. Evidence of liver damage as lipofuscin and discoloration was found in both species but only correlated with liver mercury concentration in spotted gar. Inorganic mercury was the predominant form in gar livers. In order to determine the role of mercury speciation in fish liver damage, a laboratory feeding study was employed. Zebrafish (Danio rerio) were fed either a control (0.12 ± 0.002 µg Hg.g-1 dry wt), inorganic mercury (5.03 ± 0.309 µg Hg.g-1 dry wt), or methylmercury (4.11 ± 0.146 µg Hg.g-1 dry wt) diet. After 78 days of feeding, total mercury was highest in the carcass of zebrafish fed methylmercury (12.49 ± 0.369 µg Hg.g-1 dry wt), intermediate in those fed inorganic mercury (1.09 ± 0.117 µg Hg.g-1 dry wt), and lowest in fish fed the control diet (0.48 ± 0.038 µg Hg.g-1 dry wt).

Well-Being and Academic Success in Gifted College Students: Early-College Entrants and Honors College Students

As a society, we seek to have our young people, including the gifted, be healthy and happy, and go to good schools with good teachers. Framed by Sayler's theoretical model of giftedness and thriving, this study examined psychological constructs (i.e. general self-efficacy, theories of intelligence, hope, gratitude, religiosity, disposition, and resiliency) to determine their mediating effect on personal well-being and academic success in gifted college students. The 213 subjects for this study included gifted college students from two distinct programs at the University of North Texas. One hundred twenty-two participants were students from the Texas Academy of Mathematics and Science (TAMS). TAMS is an early-college entrance program allowing gifted students to enter college after their sophomore year of high school. Ninety-one participants attended the UNT Honors College. Honors College students are gifted students who enter college after high school graduation. Latent transition, latent class, general linear model repeated measures, and regression analyses were used in the examination of the data. Results of the study revealed that positive disposition and hope-agency were significantly related to the development of personal well-being for gifted students during their first year of college. The ability to identify pathways to goals and the self-theory of intelligence …

Using Financial Rankings to Identify Characteristics of Libraries Serving Highly Profitable Private Law Firms

This purpose of this study was to develop evidence of a relationship between law libraries and private law firm profitability for law library administrators to use when making strategic decisions that influence the value of their libraries. The highest ranked administrator at each private law firm listed on the 2008 Am Law 200 was invited to complete an online benchmarking survey. The adjusted sample population totaled 179 firms. Fifty-one valid surveys were completed for a 28.5% response rate. Descriptive and statistical analyses were conducted using 26 independent variables (law library characteristics) and a single dependent variable, Revenue per Equity Partner, developed from data published for the Am Law 200. The most significant contributions of this study are: development of important law library financial and return on investment benchmarks; a listing of characteristics that have been empirically shown to impact law firm productivity; identification of optimum reporting structure for the law library administrator. Six characteristics positively impact Revenue per Equity Partner: to whom the library Administrator reports, number of library staff per library, number of Library staff per library, range in hourly bill rate for library staff time, practice areas most often supported. Two monetary measures were also established. The cost …

"The Wider View": Engaging a New Generation of Singers through African-American Art Song

Through studying the poetry and its context, the lives of the poets and composers, and the musical choices which emerged from these combined influences, students of the "Millennial" generation may experience a deeper connection to art song and its role in defining and reflecting national character. Not yet a part of the traditional canon of American art song, the songs of African-American composers are of particular value in this regard, offering teachers, students, and recitalists less frequently-performed repertoire to explore. Representing a broad spectrum of literary and cultural influences, these songs are just as diverse, multi-faceted, and full of variety as any other body of art song repertoire and richly contribute to the past and present life of the genre. Going beyond the music and the words can only reinforce the study of technique and enrich the studio experience, while at the same time providing a multicultural learning environment which more accurately reflects the America in which these same students will become the singers and voice teachers of tomorrow.

Functional Neural Toxicity and Endocrine Responses in Mice Following Naphthalene Exposure (open access)

Functional Neural Toxicity and Endocrine Responses in Mice Following Naphthalene Exposure

Polycyclic aromatic hydrocarbons (PAHs) are a well studied and diverse class of environmental toxicants. PAHs act via the aryl hydrocarbon receptor (AhR), and studies have suggested that PAHs may elicit neurological and estrogenic effects. Doses of PAHs between 50 to 150 ppm may elicit neurotoxicity in rodent models. The present study investigated the effects of naphthalene on in vivo steroidogenesis in Swiss Webster male mice, and in vitro neural function of Balb-C/ICR mice frontal cortex neurons. These data suggest that naphthalene may not elicit steroidogenic effects at concentrations ranging from 0.2 to 25 mg/kg/day, following a 7 day subcutaneous dosing regime. In addition, naphthalene may cause functional toxicity of frontal cortex neurons at concentrations of 32 to 160 ppm naphthalene.

Life without Parole for Juvenile Offenders: Questions of Legality and Adolescent Culpability (open access)

Life without Parole for Juvenile Offenders: Questions of Legality and Adolescent Culpability

Life without parole for juvenile offenders is a controversial issue across the globe. Recently, the United States stands alone as the only country in the world that allows juvenile offenders to be sentenced to life time confinement without the possibility of parole. Furthermore, the U.S. has seen an increase in juvenile waivers and blended sentences, which has resulted in harsher penalties for juvenile offenders who have committed serious and violent crimes. This analysis examines scientific evidence that shows juveniles are different from adults in terms of brain development, rational decision making abilities, and maturity levels. These findings have questioned the reasoning behind imposing adult punishment on adolescent behavior. This analysis also presents the legal arguments suggesting that juvenile life without parole is unconstitutional and violates the Eighth and Fourteenth Amendments. Arguments for and against life sentences were also presented. This study concludes with a discussion of policy implications, whether the U.S. Supreme Court should abolish juvenile life without parole sentencing practices and explores the possible future direction of juvenile sentencing in the United States.

The Cimbasso and Tuba in the Operatic Works of Giuseppe Verdi: A Pedagogical and Aesthetic Comparison (open access)

The Cimbasso and Tuba in the Operatic Works of Giuseppe Verdi: A Pedagogical and Aesthetic Comparison

In recent years, the use of the cimbasso has gained popularity in Giuseppe Verdi opera performances throughout the world. In the past, the tuba or the bass trombone was used regularly instead of the cimbasso because less regard was given to what Verdi may have intended. Today, one expects more attention to historical precedent, which is evident in many contemporary Verdi opera performances. However, the tuba continues to be used commonly in performances of Verdi opera productions throughout the United States. The use of the tuba in the U.S. is due to a lack of awareness and a limited availability of the cimbasso. This paper demonstrates the pedagogical and aesthetic differences between the use of the tuba and the modern cimbasso when performing the works of Giuseppe Verdi operas.
