Towards an Analytical Capacity in Costing of Abatement Options for Forestry and Agricultural Carbon Sinks
This document is part of Technical Report (ref: EUR 21758 EN) from the Joint Research Centre and presents part of the modelling work conducted by DG JRC/IPTS as a contribution to the DG ENV Communication on post-2012 climate policy analysis (June 2005). The analysis with the POLES and GEM-E3 models show that the costs of abatement policies, both in marginal terms and total terms, can be significantly reduced if emissions trading and project based mechanisms are used.

Michael Daugherty's Red Cape Tango: A Comparative Study of the Original Version for Symphony Orchestra and its Transcription for Wind Orchestra, with Four Recitals of Selected Works by Beethoven, Dvorák, Verdi, Bartók and Daugherty
Access:
Use of this item is restricted to the UNT Community
Michael Daugherty has created his niche in the music world by composing works inspired by icons of American popular culture. Red Cape Tango is the final movement of his Metropolis Symphony, a work inspired by the life and times of the comic book character Superman. This movement in particular deals with the death of the superhero through the use of musical elements, most notably the Latin Sequence of the Mass for the Dead, Dies irae. Daugherty's ingenuity in blending profoundly dark subjects with humor is particularly evident in this work. Death is personified as a temptress and lures Superman through the power of a seductive tango. This study concentrates on Daugherty's compositional style and its impact in musical circles. A transcription for wind orchestra was created by another composer/conductor precisely because of the need to bring such an important work to another medium, thus making it accessible to a wider audience. In addition, this study looks at the changes in instrumentation necessary to create a second, equally formidable version of the work.

Monte Carlo simulation and experimental studies of the production of neutron-rich medical isotopes using a particle accelerator.
Access:
Use of this item is restricted to the UNT Community
The developments of nuclear medicine lead to an increasing demand for the production of radioisotopes with suitable nuclear and chemical properties. Furthermore, from the literature it is evident that the production of radioisotopes using charged-particle accelerators instead of nuclear reactors is gaining increasing popularity. The main advantages of producing medical isotopes with accelerators are carrier free radionuclides of short lived isotopes, improved handling, reduction of the radioactive waste, and lower cost of isotope fabrication. Proton-rich isotopes are the result of nuclear interactions between enriched stable isotopes and energetic protons. An interesting observation is that during the production of proton-rich isotopes, fast and intermediately fast neutrons from nuclear reactions such as (p,xn) are also produced as a by-product in the nuclear reactions. This observation suggests that it is perhaps possible to use these neutrons to activate secondary targets for the production of neutron-rich isotopes. The study of secondary radioisotope production with fast neutrons from (p,xn) reactions using a particle accelerator is the main goal of the research in this thesis.

Gender and Desire in Thomas Lovell Beddoes' The Brides' Tragedy and Death's Jest-Book
Access:
Use of this item is restricted to the UNT Community
Thomas Lovell Beddoes' female dramatic characters are, for the most part, objectified and static, but these passive women perform a crucial narrative and thematic function in the plays. Alongside the destructive activity of the male characters, they dramatize masculine-feminine unions as idealized and contrived and, thus, unstable. Desire, power and influence, as well as the constrictive aspects of physicality, all become gendered concepts in Beddoes' plays, and socially normative relationships between men and women, including heterosexual courtship and marriage, are scrutinized and found wanting. In The Brides' Tragedy, Floribel and Olivia, the eponymous brides, represent archetypes of innocence, purity, and Romantic nature. Their bridegroom, Hesperus, embodies Romantic masculinity, desiring the feminine and aspiring to androgyny, but ultimately unable to relinquish masculine power. The consequences of Hesperus' attempts to unite with the feminine other are the destruction of that other and of himself, with no hope for the spiritual union in death that the Romantic Hesperus espouses as his ultimate desire. Death's Jest-Book expands upon the theme of male-female incompatibility, presenting heterosexual relationships in the context of triangulated desire. The erotic triangles created by Melveric, Sibylla, and Wolfram and Athulf, Amala, and Adalmar are inherently unstable, because they depend upon the …

Reproductive Health in Yemen: A Theoretical Approach
Several developing countries introduced family planning programs to reduce their population growth rates. The rapid spread of birth control programs in the developing countries was at times accompanied by measures which violated human rights. In response to the ethical violations and coercive policies on population control, toward the end of 1980s various international committees formulated a reproductive health approach to overcome the limited population control approach. Unlike other population control programs, the focus of reproductive health program is on “reproductive process,” where as the most immediate focus of family planning programs is on fertility. Although studies refer to reproductive health approach as an extension of fertility control approach, literature on reproductive health provides very few systematic approaches toward developing explanations of reproductive health. The current approaches on population control are influenced by the ideological shift towards a broad-based approach which involves fertility or family size as one of the components of reproductive health. The present study uses intermediate variables framework suggested by Davis and Blake to organize reproductive health explanations. The proposed framework suggests that the state of reproductive health is indicated by intercourse, conception, and gestation variables and assumes that reproductive health is a latent dimensional outcome indicated by …

Neckbones and Sauerfowches: From Fractured Childhood in the Ghetto to Constantly Changing Womanhood in the World
A collection of five memoiristic essays arranged about themes of family, womanhood and the African-American community with a preface. Among the experiences the memoirs recount are childhood abandonment; verbal and emotional child abuse; mental illness; poverty; and social and personal change. Essays explore the lasting impact of abandonment by a father on a girl as she grows into a woman; the devastation of family turmoil and untreated mental illness; generational identity in the African-American community. One essay describes the transition from the identity-forming profession of journalism to academia. The last essay is about complicated and conflicting emotions toward patriotism and flag-waving on the part of a black woman who has lived through riots, little known police shootings of students on black campuses, and many other incidents that have divided Americans.

Loss of Innocence
Loss of Innocence uses sculpture, two-dimensional imagery, and text to explore the moment when children lose their innocence or realize their mortality. In the introduction, I explain that there are many factors, such as age and personality, which determine how children will deal with traumatic events in their lives and the duration of time that must pass before they move past the event. Often, children will combine childhood fantasy with random facts to create their own satisfactory explanation of what has happened. In my problem in lieu of thesis, I discuss work that I created with these thoughts in mind. I explore how the sculpture, two-dimensional imagery, and text work together to convey the emotion of innocence lost.

A Comparison of Aural and Visual Instructional Methodologies Designed to Improve the Intonation Accuracy of Seventh Grade Violin and Viola Instrumentalists.
The purpose of the study was to compare two instructional methodologies designed to improve the intonation accuracy of seventh grade violin and viola instrumentalists. The collection of data was in regard to (1) instructional methodology: aural and aural/visual, (2) performance tasks: A, B, and C; (3) individual pitches (seven from each of the music tasks), and (4) differences between instrument groups: violin and viola. Sixty-eight seventh grade string students from three string classes of two middle schools were randomly assigned to two experimental groups: (a) aural and (b) aural/visual. The instructional period was implemented daily in ten-minute sessions during twenty days by the orchestra instructors of each school. A pretest-posttest format was used to determine if there were any changes in the subjects' intonation accuracy from prior to after the instructional phase was implemented, and if these changes could be attributed to any of the methodologies. The testing material used on both testing sessions included three performance tasks composed of seven notes each. Subjects were recorded on both testing occasions. The data were the scores of absolute pitch deviation, measured in cents from equal temperament, from the pre- and postest; these were treated with analysis of variance. The ANOVA on …

Molecular cloning and analysis of the genes for cotton palmitoyl-acyl carrier protein thioesterase (PATE) and Δ-12 fatty acid desaturase (FAD2-3) and construction of sense and anti-sense PATE plasmid vectors for altering oilseed composition of transgenic cotton plants.
A cotton PATE cDNA clone has a 1.7-kb insert with an coding region for 410 amino acids, lacking codons for the three N-terminal amino acids. The predicted amino acid sequence of the PATE preprotein has a characteristic stromal-targeting domain and a 63% identity to the Arabidopsis FatB1 thioesterase sequence. A cotton genomic clone containing a 17.4-kb DNA segment was found to encompass a palmitoyl-ACP thioesterase (FatB1) gene. The gene spans 3.6 kb with six exons and five introns. The six exons are identical in nucleotide sequence to the open reading frame of the corresponding cDNA, and would encode a preprotein of 413 amino acids. The preprotein is identified as a FatB thioesterase from its deduced amino acid sequence similarity to those of other FatB thioesterase preproteins. A 5'-flanking region of 914 bp was sequenced, with the potential promoter/enhancer elements including basic helix-loop-helix elements (E box). Alkaline blot hybridization of cotton genomic DNA suggests the presence at least two FatB1 thioesterase genes in cotton. Four plasmid constructs for both constitutive and seed-specific anti-sense RNA suppression and gene-transgene co- suppression of PATE gene expression were successfully generated. Two overlapping cotton genomic clones were found to encompass a Δ-12 fatty acid desaturase (FAD2-3) …

A Content Analysis of Reading Software Commercially Available for Pre-K to 3rd Grade Children.
The purpose of this qualitative study was to investigate the content and characteristics of the currently available commercial reading software for Pre-K through third grade children. The design of the study was a content analysis. Based on the evaluation rubric established by the researcher, ten commercial reading software were selected to be analyzed. By reviewing and transcribing, the data were obtained, and then coded, categorized, and interpreted. The findings from the analysis revealed that all reading software programs offered exercised for practicing basic phonics skills; the alphabetic principle, letter-sound association, word knowledge, sentence building, and reading comprehension. Depending on the software developers, phonics-based practice was presented in two ways; separate skill-based practice emphasis and storybook-reading emphasis. All software programs utilized drill-and-practice, direct instruction and mastery learning methods and utilized gaming strategies to motivate and engage the learners. Multimedia technology was used to make the software more appealing. All reading software programs were developed on the perspectives that view learning to read as the continuum of a child's oral language development and background experience about words. It is recommended that parents and teachers review and select the software based on reliable information sources, use the software as supplementary practice based on …

Autoradiographic Localization of Carbachol-Induced Second Messenger Response in the Rat Spinal Cord Following Inflammation.
This study examined central mechanisms of persistent pain using an autoradiographic technique to localize phosphoinositide hydrolysis (PI) in the rat spinal cord dorsal horn. The lateral half of laminae I-II showed the highest levels of baseline PI turnover and carbachol-stimulated PI turnover in normal animals as well as after inflammation. Inflammation resulted in increased baseline PI turnover in this region of the ipsilateral (76%) and contralateral (65%) dorsal horns. Carbachol increased PI turnover in this region in normal rats (55%) and following inflammation (ipsilateral: 46%, contralateral: 45%). The absolute magnitudes of these increases were 1.85, 2.71, and 2.51 nCi/mg, respectively. The results of this study demonstrate the involvement of PI turnover in neural mechanisms of persistent pain, and provide evidence for the involvement of cholinergic systems in this process. Because spinal cholinergic systems have been reported to be anti-nociceptive, the present results appear to reflect an upregulation of anti-nociceptive activity in response to inflammation. Thus, the spinal cholinergic system may be a regulatory site within the anti-nociceptive pathway, and may provide an attractive target for the development of new therapeutic agents.

Marxian and Weberian theory as explanations of the effects of industrialization on town development: A case study; Denison, Texas.
While a great deal of historical literature has concentrated on the effects of industrialization on town development, most of the accounts relate to the introduction of industrialization into an established town. This study attempts to analyze, in sociological terms, the effects of industrialization (in this case, the emergence of the railroad) on the social structure of Denison, Texas which was created by industrialization. It is an attempt to combine Marxian and Weberian theory to produce a multi-dimensional theory that can explain town development without the usual economic bias as evident in most contemporary theory. This study proceeds on the assumption that the social order of a newly formed community is not based solely on economic factors. While economic considerations were important for the town of the study, social stability of the town was maintained by other “non-economic” elements. The purpose of the study is to construct a composite theory that can be utilized to analyze town development. The thrust is not the creation of new theory, rather it attempts to combine existing “classical” theories to present a balanced and, to an extent, “objective” explanation of community development. Adding the social aspects of Weber's theory to Marx's theory results in a …

An evaluation of job satisfaction among salespersons in a small department store using four psychological measures.
The purpose of this study was to examine the potential of three independent psychological scales (Rotter's Locus of Control, Karasek's Job Content Questionnaire [non-injury job stress], and Rosenberg's Self-Esteem Scale) to predict job satisfaction, as measured by Brayfield and Rothe's Index of Job Satisfaction, among salespersons in a small independent department store in Wichita Falls, Texas. An 82-item survey which examined the dynamics of a salesperson's work life was administered to 20 individuals who were full-time employees of the department store. Demographic data were also gathered although these factors were not entered into the regression analysis. A multiple regression procedure examined the responses of the 20 employees who participated in the study. The R-squared coefficient indicates that 41 percent of the variance in Job Satisfaction was explained by the three predictor measures. A major proportion of this unexplained variance may be in variables outside the scope of this study, e.g., salaries, vacation time, benefits, bonuses, or commissions. Results suggest that the independent variables measured by the Locus of Control Scale and the Job Content Questionnaire in combination were the best predictors of job satisfaction with a significance level of .01. The single best predictor was the Job Content Questionnaire, significant …
