Analysis of options to move beyond 20% greenhouse gas emission reductions and assessing the risk of carbon leakage
This paper responds to the mandate given in the Emissions Trading Directive (EU ETS directive, Article 10b) to the Commission to submit by end of June 2010 an analytical report assessing the situation of energy-intensive sectors that have been determined to be exposed to significant risks of carbon leakage in the light of the international negotiations.

Analysis of options to move beyond 20% greenhouse gas emission reductions and assessing the risk of carbon leakage
This paper analyze the possible effects of implementing all high end pledges put forward by countries under the Copenhagen Accord. Among other analysis, the report predict that, (if the Copenhagen Accord would be fully implemented), the world could bridge a major part of the required efforts by 2020 in order to keep average global temperature increase below 2ºC. However, the report also argue that most high end targets are conditional on others taking similar action, on a legally binding international agreement or on the need for further international financial or technical support making their degree of implementation uncertain.

An Analysis of Performance Differences Between Self-Directed and Teacher-Directed Alternative Education Campuses in Texas
This study was conducted to analyze the performance differences between alternative education campuses in Texas that used teacher-directed strategies and those that used self-directed strategies. The study was also conducted to inform educators of the results these two strategies had achieved with at-risk students during the three years of 2006-2008. The study used the results from the Texas Assessment of Knowledge and Skills test as reported in the AEIS annual reports from the Texas Education Agency. Alternative education schools were grouped according to the strategy used to educate at-risk students. The results of the statistical tests showed the two strategies had similar performance results and there was no statistical difference between the two. The results offered several implications concerning the ability of at-risk students to achieve in alternative education schools including possible reasons why students who were previously unsuccessful became successful in alternative settings. The report also addressed the number of students who continued to be unsuccessful even when placed on an alternative education campus. Possible reasons for this continued inability to succeed are discussed. Recommendations for further research were listed at the conclusion of the study.

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.

An Analysis of UNT Commuting Patterns
Academic institutions have recently organized to address their campus' greenhouse gas emissions. Along those lines, the University of North Texas (UNT) pledged to minimize the campus' environmental impact, and conducted a transportation survey in May 2009. The analyses confirm that commuting to campus was the second highest source (29%) of UNT's greenhouse gas emissions, following purchased electricity (48%). Students, faculty and staff drive over 89 million miles per year, 84% of which comes from students. Forty‐two percent of student driving trips originate in the primary and secondary core areas surrounding Denton, which are partially served by buses. However, because these core areas are in close proximity to the campus, they contribute only 8% of the total student driving distance. Beyond the Denton core, the inner periphery of Denton County contributes another 22% of driving mileage. Students living in the outer periphery (outside Denton County) contribute the remaining 70% of total driving distance, and carpooling is currently their only alternative.

Analyzing Contingencies of Behavioral and Cultural Selection
A choice paradigm was used to evaluate allocation of interlocking behavior of two groups of two participants between responses having operant consequences only and responses having cultural consequences. In a discrete trial BABABAB design, each participant could select one of three options, which delivered either 3 or 5 points. In B (cultural consequence) conditions, two of the options had additional effects: the 3-point option also added 3 points to the other participant's earnings, and one of the 5-point options also subtracted 5 points from the other participant's earnings. The third option was unchanged in both conditions and delivered 5 points to the participant who selected it. Results indicated that participants in both groups initially frequently produced response combinations that earned 8 points for one or the other individual (and 0 or 3 points for the other), but allocation of responding increasingly changed to combinations that produced 6 points for each individual. This shift in performances away from maximum individual reinforcement towards maximum group reinforcement indicates cultural contingencies did not act in concert with operant contingencies, suggesting they are different mechanisms of selection.

Anchor Nodes Placement for Effective Passive Localization
Wireless sensor networks are composed of sensor nodes, which can monitor an environment and observe events of interest. These networks are applied in various fields including but not limited to environmental, industrial and habitat monitoring. In many applications, the exact location of the sensor nodes is unknown after deployment. Localization is a process used to find sensor node's positional coordinates, which is vital information. The localization is generally assisted by anchor nodes that are also sensor nodes but with known locations. Anchor nodes generally are expensive and need to be optimally placed for effective localization. Passive localization is one of the localization techniques where the sensor nodes silently listen to the global events like thunder sounds, seismic waves, lighting, etc. According to previous studies, the ideal location to place anchor nodes was on the perimeter of the sensor network. This may not be the case in passive localization, since the function of anchor nodes here is different than the anchor nodes used in other localization systems. I do extensive studies on positioning anchor nodes for effective localization. Several simulations are run in dense and sparse networks for proper positioning of anchor nodes. I show that, for effective passive localization, the …

Antonín Dvořák’s Piano Concerto in G Minor, Opus 33: A Discussion of Musical Intent and Pianistic Effectiveness in Vilém Kurz's Version of the Solo Piano Part
Since its premiere in 1878, Antonín Dvořák’s Piano Concerto in G Minor has been underrated and held in low regard by musicologists, critics, performers and audiences alike. Vilém Kurz (1872-1945), a Czech pianist and pedagogue, revised and reworked the piano solo part to incorporate what he considered to be added brilliance and pianistic effectiveness. However, the revised version has not increased the popularity of the work. In recent decades, this concerto has begun to appear more often in the programs and recordings are currently available, utilizing either the original piano part or Kurz's revision or a combination of both. In order to gain a broader analytical perspective and achieve a more authentic interpretation of the piece, a thorough understanding of the relation between Dvořák’s work and Kurz's revisions is indispensable. This study examines these adaptations and compares them with Dvořák’s scoring in order to gain further insight to Kurz's musical intent and pianistic aims. Examples from all movements are evaluated vis-à-vis the original to determine their purpose and musical validity.

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy
This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but …

Archaeological Proteomics: Method Development and Analysis of Protein-Ceramic Binding
The analysis of protein residues recovered from archaeological artifacts provides a unique opportunity to reveal new information about past societies. However, many scientists are currently unwilling to accept protein-based results due to problems in method development and a basic lack of agreement regarding the ability of proteins to bind to, and preserve within, artifacts such as pottery. In this paper, I address these challenges by conducting a two-phase experiment. First, I quantitatively evaluate the tendency of proteins to sorb to ceramic matrices by using total organic carbon analysis and spectrophotometric assays to analyze samples of experimentally cooked ceramic. I then test a series of solvent and physical parameters in order to develop an optimized method for extracting and preparing protein residues for identification via mass spectrometry. Results demonstrate that protein strongly sorbs to ceramic and is not easily removed, despite repeated washing, unless an appropriate extraction strategy is used. This has implications for the future of paleodietary, conservation ecology and forensic research in that it suggests the potential for recovery of aged or even ancient proteins from ceramic matrices.

An Assessment of Consumers' Willingness to Patronize Foreign-Based Business Format Franchises: An Investigation in the Fast-Food Sector
This study aimed to address consumers' stereotypical categorizations in the form of essentialist views about foreign cultures and their effect on individual consumers, including their negative or aroused emotions and subsequent retail patronage behaviors. The research mission was to empirically assess the salient dimensions of consumers' states of mind (positive and negative affect, psychological essentialism, epistemic curiosity), states of being (store atmospherics), and states of action (retail patronage behaviors) in a cultural context based on Mehrabian-Russell theory of environmental psychology. Specifically, the retail patronage setting was selected as foreign-based fast-food franchises because it represents both a relevant and timely situational context for consumer behavior. This dissertation makes several contributions to international retail patronage literature. First, it frames curiosity as an aroused emotional state and finds support for the relationship between consumer epistemic curiosity and retail patronage. Second, it provides support for the linkage between consumer affect and retail patronage in an international retail setting. Third, it reveals that affect has a greater impact on retail patronage than epistemic curiosity. The overarching finding of this study is an inability to tie the cultural elements in retail atmospherics, including signs, symbols, and artifacts, to consumer emotions. In addition, we were unable to …

An Assessment of Undergraduate Course Syllabi in the Departments of English at Universities in Taiwan
This exploratory, qualitative research explored the extent that course syllabi in the Departments of English in 13 public and 9 private universities in Taiwan reflect the inclusion of syllabus components to promote learning as recommended in the literature in the United States. Research questions included: what components can be inferred from the literature in the U.S. for the recommended components of a course syllabus, for the components for a learning-centered syllabus, and for a model to analyze Bloom's cognitive level of learning? And when these are applied to analyze course syllabi in English courses, are syllabi in these universities congruent with the models? The research identified and analyzed 235 course syllabi from the core courses listed online at these universities. The findings indicated that these syllabi are highly congruent with the syllabus components template; 68% of the syllabi included seven or more of the ten components. Additionally, these syllabi reflect medium congruency with the learning-centered syllabus template. Verbs used in objectives and learning outcomes in different English courses indicate different levels of cognitive learning goals as identified by Bloom's cognitive domain. Additional findings indicate that there was no difference in inclusion of components based on where faculty earned their doctoral …

Atomistic Studies of Point Defect Migration Rates in the Iron-Chromium System
Generation and migration of helium and other point defects under irradiation causes ferritic steels based on the Fe-Cr system to age and fail. This is motivation to study point defect migration and the He equation of state using atomistic simulations due to the steels' use in future reactors. A new potential for the Fe-Cr-He system developed by collaborators at the Lawrence Livermore National Laboratory was validated using published experimental data. The results for the He equation of state agree well with experimental data. The activation energies for the migration of He- and Fe-interstitials in varying compositions of Fe-Cr lattices agree well with prior work. This research did not find a strong correlation between lattice ordering and interstitial migration energy

Attenuation of the Squared Canonical Correlation Coefficient Under Varying Estimates of Score Reliability
Research pertaining to the distortion of the squared canonical correlation coefficient has traditionally been limited to the effects of sampling error and associated correction formulas. The purpose of this study was to compare the degree of attenuation of the squared canonical correlation coefficient under varying conditions of score reliability. Monte Carlo simulation methodology was used to fulfill the purpose of this study. Initially, data populations with various manipulated conditions were generated (N = 100,000). Subsequently, 500 random samples were drawn with replacement from each population, and data was subjected to canonical correlation analyses. The canonical correlation results were then analyzed using descriptive statistics and an ANOVA design to determine under which condition(s) the squared canonical correlation coefficient was most attenuated when compared to population Rc2 values. This information was analyzed and used to determine what effect, if any, the different conditions considered in this study had on Rc2. The results from this Monte Carlo investigation clearly illustrated the importance of score reliability when interpreting study results. As evidenced by the outcomes presented, the more measurement error (lower reliability) present in the variables included in an analysis, the more attenuation experienced by the effect size(s) produced in the analysis, in this …

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.

Bad Blood: Impurity and Danger in the Early Modern Spanish Mentality
The current work is an intellectual history of how blood permeated early modern Spaniards' conceptions of morality and purity. This paper examines Spanish intellectuals' references to blood in their medical, theological, demonological, and historical works. Through these excerpts, this thesis demonstrates how this language of blood played a role in buttressing the church's conception of good morals. This, in turn, will show that blood was used as a way to persecute Jews and Muslims, and ultimately define the early modern Spanish identity.
