The preface to this collection of poems, "Memory and The Myth of Lost Truth," explores the physical and metaphysical roles memory plays within poetry. It examines the melancholy frequently birthed from a particular kind poetic self-inquiry, or, more specifically, the feelings associated with recognizing the self's inability to re-inhabit the emotional experience of past events, and how poetry can redeem, via engaging our symbolic intuition, the faultiness of remembered history. Dawn in the Empty House is a collection of poems about the implications of human relationships, self-deception, and memory as a tool for self-discovery.
In the preface to this collection, "Poetry and History: Finding 'What Will Suffice,'" I show how Czeslaw Milosz's "Dedication" and Jorie Graham's "Guantánamo" embody the virtues of philosophical meditation and the moral imagination to create a unique poetry of witness. These poems also provide American poets with an example of how they can regain the trust of an apathetic general reading audience. Tinder for the Bathhouses is a collection of poems in which I use the moral imagination to indirectly bear witness to events as far ranging as the Holocaust and the Iraq War. Using the family as a foundation, I show how historical narratives can provide a poet with the tools to think about larger metaphysical questions that poetry can raise, such as the nature of beauty and the purpose of art.
The preface to this collection, "Against Expectation: The Lyric Narrative," highlights the ways James Wright, Stephen Dunn, and C.K. Williams use narrative to strengthen their poems. Where My Own Grave Is is a collection of poems that uses narrative to engage our historical fascination with death.
This study explored the state of art education in Turkey as revealed by pre-service art education university instructors, and the potential of incorporating visual culture studies in pre-service art education in Turkey. The instructors' ideas about visual culture, and popular culture, the impact it might have, the content (objects), and the practices within the context of Turkey were examined. Visual culture was examined from an art education perspective that focuses on a pedagogical approach that emphasizes the perception and critique of popular culture and everyday cultural experiences, and the analysis of media including television programs, computer games, Internet sites, and advertisements. A phenomenological human science approach was employed in order to develop a description of the perception of visual culture in pre-service art education in Turkey as lived by the participants. In-person interviews were used to collect the data from a purposive sample of 8 faculty members who offered undergraduate and graduate art education pedagogy, art history, and studio courses within four-year public universities. This empirical approach sought to obtain comprehensive descriptions of an experience through semi-structural interviews. These interviews employed open-ended questions to gather information about the following: their educational and professional background; their definitions of art education and art teacher education and what it means for them to teach pre-service art education; critical reflections on the educational system of Turkey; perceptions of visual and popular culture; and finally individual approaches to teaching art education. This study was conducted for the purpose of benefiting pre-service art teacher education in general and specifically in Turkey. It provided the rationale, the nature, and pedagogy of visual culture as well as the why and how of visual culture art education in the context of Turkey. Furthermore, it provided insights into the potential contribution of the concept of visual culture to the understanding ...
Glutathione syntethase (GS) is an enzyme that belongs to the ATP-grasp superfamily and catalyzes the second step in the biosynthesis of glutathione. GS has been purified and sequenced from a variety of biological sources; still, its exact mechanism is not fully understood. Four highly conserved residues were identified in the binding site of human GS. Additionally, the G-loop residues that close the active site during catalysis were found to be conserved. Since these residues are important for catalysis, their function was studied computationally by site-directed mutagenesis. Starting from the reported crystal structure of human GS, different conformations for the wild type and mutants were obtained using molecular dynamics technique. The key interactions between residues and ligands were detected and found to be essential for enzyme activity.
The purposes of this dissertation were to define enterprise resource planning (ERP) systems, assess the varying performance benefits flowing from different ERP system implementation statuses, and investigate the impact of critical success factors (CSFs) on the ERP system deployment process. A conceptual model was developed and a survey instrument constructed to gather data for testing the hypothesized model relationships. Data were collected through a cross-sectional field study of Indian production firms considered pioneers in understanding and implementing ERP systems. The sample data were drawn from a target population of 900 firms belonging to the Confederation of Indian Industry (CII). The production firms in the CII member directory represent a well-balanced mix of firms of different sizes, production processes, and industries. The conceptual model was tested using factor analysis, multiple linear regression analysis and univariate Anova. The results indicate that the contributions of different ERP system modules vary with different measures of changes in performance and that a holistic ERP system contributes to performance changes. The results further indicate that the contributions of CSFs vary with different measures of changes in performance and that CSFs and the holistic ERP system influences the success achieved from deployments. Also, firms that emphasize CSFs throughout the ERP implementation process achieve greater performance benefits as compared to those that focus on CSFs during the initial ERP system deployment. Overall, the results of the study support the relationships hypothesized in the conceptual model.
The state of Texas passed the Student Success Initiative (SSI) in 1999 which requires all 3rd graders to pass the reading portion of the Texas Assessment of Knowledge and Skills (TAKS) test to be promoted to the 4th grade, and for 5th graders to pass the reading and math portions of the TAKS test to be promoted to the 6th grade. Beginning in spring 2008, 8th graders will also need to pass the reading and math portions of the TAKS test to be promoted to the 9th grade. The purpose of this study was to examine the academic performance of 3rd and 5th grade students who did not meet the passing standard on the TAKS test and were retained during the 2005-2006 school year. The population of this study included 33 3rd graders and 49 5th graders who were retained during the 2005-2006 school year due to not meeting the promotion requirements of the SSI. There was also a second population of 49 5th graders who were retained in 3rd grade during the 2003-2004 school year due to not meeting the promotion requirements of the SSI. These students were enrolled in the 5th grade for the first time during the 2005-2006 school year. Their TAKS scores were examined to see whether students were still benefiting from the year of retention in 3rd grade. Results for all populations were broken down by ethnicity and program codes. The results of the study showed a statistically significant gain in 3rd grade reading and 5th grade math scores. The 5th grade reading scores did have a statistically significant improvement even though the reading mean score was still below the minimum passing score even after a year of retention. A cross tabulation done on students who had been retained in 3rd grade due to SSI ...
N-Acylethanolamines (NAEs) are endogenous lipid metabolites that occur in a variety of dry seeds, and their levels decline rapidly during the first few hours of imbibition (Chapman et al., 1999, Plant Physiol., 120:1157-1164). Biochemical studies supported the existence of an NAE amidohydrolase activity in seeds and seedlings, and efforts were directed toward identification of DNA sequences encoding this enzyme. Mammalian tissues metabolize NAEs via an amidase enzyme designated fatty acid amide hydrolase (FAAH). Based on the characteristic amidase signature sequence in mammalian FAAH, a candidate Arabidopsis cDNA was identified and isolated by reverse transcriptase-PCR. The Arabidopsis cDNA was expressed in E. coli and the recombinant protein indeed hydrolyzed a range of NAEs to free fatty acids and ethanolamine. Kinetic parameters for the recombinant protein were consistent with those properties of the rat FAAH, supporting identification of this Arabidopsis cDNA as a FAAH homologue. Two T-DNA insertional mutant lines with disruptions in the Arabidopsis NAE amidohydrolase gene (At5g64440) were identified. The homozygous mutant seedlings were more sensitive than the wild type to exogenously applied NAE 12:0. Transgenic seedlings overexpressing the NAE amidohydrolase enzyme showed noticeably greater tolerance to NAE 12:0 than wild type seedlings. These results together provide evidence in vitro and in vivo for the molecular identification of Arabidopsis NAE amidohydrolase. Moreover, the plants with altered NAE amidohydrolase expression may provide new tools for improved understanding of the role of NAEs in germination and seedling growth.
Ninety elementary public school teachers were surveyed to find out where they obtained their teaching ideas. Seven popular elementary-level teaching periodicals, dated 1989-1999, were analyzed for aging-related content, and compared with 27 of the National Academy for Teaching and Learning about Aging (NATLA) aspects of aging recommended for students' learning. Results indicate that public elementary teachers obtain their teaching ideas from various places: teaching institutes or workshops; other teachers; ideas or lessons they develop themselves; and teaching periodicals. A large percentage obtain lesson ideas from teaching periodicals that they browse or read. This finding may assist NATLA in making recommendations to particular editorial boards. Surprisingly, few teachers obtain their teaching ideas from state and local curricular mandates. When the periodical issues were analyzed, aging-related content was categorized in four ways: informational articles with selected teaching or learning activities; articles describing intergenerational programs or activities; book reviews with selected learning activities; and book review titles mentioning older adult characters. Category totals among the 7 periodicals were highest in book review titles mentioning older adult characters and book reviews with selected learning activities. The content was compared to NATLA's recommendations for students' learning. The findings were not significant. The aging aspect that appeared most often in book reviews with selected learning activities was that most living things have life cycles of patterned biological changes, and/or that death and disability can occur at any age. Whether we formally teach them about aging or not, children learn about it. Earlier studies indicate that even preschool children may stereotype the aging process and/or older adults. Curricular and instructional ideas provided in teaching materials, even in an informal format can provide education, which prepares children for real life experiences.
Due to concern about diminishing landfill space, the City of Denton contracted a municipal solid waste characterization study in 1999 that would identify materials for diversion. This paper describes the results of 5 1-week waste sorting events, a scale-house analysis, a recycling participation study, a recycler profile and a similar city study. The results of the characterization studies suggest that at least 50% of each waste stream is recyclable or divertible though paper products accounted for no more than 45% by weight of any waste stream. Curbside recycling participation rate was 71% during the 6-week study period though the average weekly set-out rate was 37%. Recycling participation rates varied significantly by zip code and by home value categories but not by gender. Denton is fairly progressive in its waste management approach when compared to demographically similar cities on a 15-question assessment though recommendations for improvement have been identified.
All information for this study was obtained by original source documents, interviews with the principal participants and the personal observations of the writer. A complete transcript of interviews with Daron Aric Hagen Michael Haithcockand Robert De Simone are included as appendices. In1961 the College Band Directors National Association (CBDNA) created its commissioning project for the purpose of contracting prominent composers to contribute works of high quality to the growing wind repertoire. Recently, CBDNA commissioned works that sought to collaborate with other disciplines within the artistic community. These collaborative works added new depth to the wind repertoire and helped advance the genre to new levels of prominence. CBDNA commissioned Daron Aric Hagen to write an opera using winds in the pit. He titled the work Bandanna, based on Shakespeare's Othello. Hagen contracted Paul Muldoon to write the libretto. A consortium of 79 member schools contributed to the project. A total of $100,000.00 was paid to the composer. The Director of Bands at Baylor University conducted the premiere performance of Bandanna during the 1999 CBDNA convention on 25 February 1999. Hagen assigned instrumental, thematic and harmonic attributes to each character. There are literally thousands of interactions between these elements that weave a tight pattern of organic unity into the entire work, making it exceptionally rich with symbolism and innuendo. Though still in its infancy, the uniqueness of this work both in the manner in which it came into being and through its artistic merits are fascinating. Only the future will determine whether Bandanna has true longevity or will fade into the background as a historical curiosity.
A longitudinal study of infants and their mothers was conducted to explore the development of imitation and approximations to imitation. During a 10-minute unstructured play session, researchers observed two mother-infant dyads once per week for twelve weeks, while they played at home. The data presented represents infants between the ages 5 and 34 weeks. The methodology employed was based on the methods described by Hart and Rilsey (1999). Observations were coded based on the topography of the mother's and infant's behavior and included vocalizations, facial movements, motor movements, and object manipulation. The data are analyzed and discussed in terms of its relevance to autism intervention.
Texas programs in pre-service art teacher preparation vary little. Since 1970, the National Art Education Association (NAEA) has created voluntary standards in hopes of decreasing variability among programs. In 1999, the NAEA published Standards for Art Teacher Preparation, outlining 20 content areas that art pre-service programs should provide their students. To obtain information on the implementation and the extent to which these 20 standards are being implemented, a questionnaire was sent to all programs in Texas. The 20 standards were the dependent variable for the study. The four independent variables used in this ex post facto study were: the size of the institution where the program exists; the number of full-time art faculty; the number of full-time art education faculty; and, the number of undergraduate art education students who graduated last year. The 20 standards or provisions were scored on a Lickert scale with six options: zero (not taught) to five (comprehensively taught). The response size (N = 23) was 47% of the state's 49 approved programs. The results from the survey suggest no significant difference among programs. However, the results showed a significant difference in the number of provisions taught between programs with no art educators and those with 1 to 3 art educators. One art educator seemed to increase the number of pedagogical provisions taught but did not increase the extent or enhance the degree to which each provision was taught. A comprehensively taught response to the NAEA provisions on the questionnaire was further investigated through analysis of catalog course descriptions and correspondence with participants. The results are estimated in credit hours and indicate that there may be a point where time on task decides the limit that constitutes a comprehensive preparation. Perspectives on content are discussed and regarded as too subjective to define comprehensive preparation. Comprehensive time ...
The purpose of this study was to determine whether coaching behavior preferences of interscholastic athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnaire (CBQ; Martin & Barnes, 1999) was administered to 372 interscholastic athletes. The mean scores of the participants' responses to each subscale on the CBQ were the dependent variables and gender and type of sport were the independent variables. Descriptive statistics revealed that female and male interscholastic athletes who perform on coactive, mixed, and interactive sport teams preferred coaches who engage in supportive and instructional behaviors, as opposed to non-responses or negative responses. A 2 (Gender) X 3 (Type of Sport) MANOVA and discriminant function analyses indicated that gender and the degree of interdependency between group members affects preferred coaching behavior. Thus, coaches should consider situational factors and personal characteristics when working with interscholastic athletes.
Let H be a separable infinite dimensional complex Hilbert space, let U(H) be the Polish topological group of unitary operators on H, let G be a Polish topological group and φ:G→U(H) an algebraic isomorphism. Then φ is a topological isomorphism. The same theorem holds for the projective unitary group, for the group of *-automorphisms of L(H) and for the complex isometry group. If H is a separable real Hilbert space with dim(H)≥3, the theorem is also true for the orthogonal group O(H), for the projective orthogonal group and for the real isometry group. The theorem fails for U(H) if H is finite dimensional complex Hilbert space.
Expanding interests may be a behavioral cusp, resulting in widespread changes across skills, and therefore is particularly relevant in intervention programs for children with autism. Little research has addressed directly increasing the diversity of activities and interests for this population. This study describes a program developed to increase activities and interests in a girl dually-diagnosed with pervasive developmental disorder (PDD-NOS) and Downs syndrome (DS). A multiple-baseline design across stimuli was employed to evaluate the program. The results show that the program increased number of total and different toy interactions. No effects were observed for overall duration of toy interactions. Results are discussed in relation to play skill instruction and preference assessment literature, the cusp, and autism intervention programs.
Computer technology has been used in education for years, and the government budgets large amounts of money to foster technology. However, it is still a debated whether computer technology makes a difference in students' learning outcomes. The purpose of this study is to find if any relationship exists between computer use by teachers and students and the students' academic achievement in math and reading for both traditional populations and English language learner (ELL) tenth graders. Computer use in this study included the computer activities by students and teachers, in terms of the time, frequency, activities types, the places students use computers, teachers' computer activities, and the training teachers received. This study used data gathered from tenth grade students from the dataset Education Longitudinal Study of 2002 (ELS:2002) of the National Center for Education Statistics (NCES). Fifteen thousand, three hundred and sixty-two students were randomly selected to represent all U.S. tenth-graders attending schools in 2002. The findings showed diverse relationships consistent with the literature. Based on the findings, some suggestions were made to teachers and parents about the quality of school work and computer use by students and teachers.
This study sought to discover job satisfaction factors of African American faculty at a historically black university and a predominantly white institution. Data were gathered through the use of semi-structured interviews of 6 faculty members from a historically black university and 5 faculty from a predominantly white institution. Several themes emerged from the study. The most salient was that African American faculty at the historically black university were satisfied by their work with students, satisfied with the flexibility of their schedules, and dissatisfied with their pay, workload, and the lack of recognition that they receive from their institution. African American faculty at the predominantly white institution were satisfied by the impact the programs and courses they developed had upon students, satisfied with their job's freedom and flexibility, and dissatisfied with the ideas of being micromanaged or working with people who are not open and honest. The findings of this study showed that service is an important factor to job satisfaction of African American faculty and that there is a distinction between factors faculty are dissatisfied with but willing to endure and those that would cause them to leave an institution.
Jazz improvisation provides a case context for examining information in music; entropy provides a means for representing music for retrieval. Entropy measures are shown to distinguish between different improvisations on the same theme, thus demonstrating their potential for representing jazz information for analysis and retrieval. The calculated entropy measures are calibrated against human representation by means of a case study of an advanced jazz improvisation course, in which synonyms for "entropy" are frequently used by the instructor. The data sets are examined for insights in music information retrieval, music information behavior, and music representation.
The purpose of this research is to empirically investigate consumers' health care decision choices in a dynamic market setting. The unprecedented demands on the U.S. health care system coupled with the mounting controversies surrounding health care reform suggest that consumers' health care decisions warrant empirical research attention. Toward this end, this dissertation empirically explored (1) the characteristics of consumers who possess a willingness to use non-conventional treatments over conventional treatments, (2) the characteristics of consumers who elect self-medication in lieu of health care practitioner-directed medication, and (3) the salient dimensions of consumers' channel choice for the procurement of health care products. Each of these decision choice factors were tested across two U.S. generational segments to assess whether differences existed across Baby Boomers' and Gen Yers' health care decision choices. The conceptual framework for empirical assessment is Bandura's (1986) social cognitive theory. From Bandura's social cognitive theory, a general model of healthcare decision choice is proposed to assess consumers' states of mind, states of being and states of action (decision choice). Results indicate that social cognitive factors (e.g., self-efficacy, objectivism) play an important role in each of the decision domains explored in this dissertation. Moreover, health value was found to be an important moderator between the social cognitive factors and health care decision choices. The predictors of the health care decision choices were found to vary across the Baby Boomers and Generation Yers on several dimensions, confirming the notion that generational differences may be a salient dimension of consumers' health care decision choice. The research offers several implications for practitioners, academicians and policy makers. Both descriptive and normative implications are gleaned from the research findings. Most notably, the results indicate that consumers' social cognitive factors and health value may be mechanisms for managing health care decisions.
Watershed I/IV, for Solo Percussion and Real-time Computer Spatialization was composed in 1995 by Pulitzer prize-winning composer Roger Reynolds. This work is a 25-minute choreographed music drama for one multiple-percussionist, in which Reynolds incorporates the musical transformation of percussion instrument families, the physical gestures of the performer, and the spatialization of processed sounds around the audience. This dissertation addresses several aspects of Watershed, which include: the expressive intent and extra-musical concepts; the formal organization, and several non-musical tools that Reynolds utilized in designing the piece (e.g. logarithmically derived sequences); the primary musical motives; the instrument setup and how the resulting physical gestures contribute to the musical intent; and the real-time computer spatialization. Throughout the document, specific musical passages are demonstrated with notated musical examples and embedded video/audio clips. In addition, transcripts of my interviews with composer Roger Reynolds, percussionist Steven Schick (premiere performer of Watershed) and engineer/technician Greg Dixon (engineer for my performances of Watershed IV) are also included.
Oxygen deprivation can be pathological for many organisms, including humans. Consequently, there are several biologically and economically relevant negative impacts associated with oxygen deprivation. Developing an understanding of which genes can influence survival of oxygen deprivation will enable the formulation of more effective policies and practices. In this dissertation, genes that influence adult anoxia survival in the model metazoan system, C. elegans, are identified and characterized. Insulin-like signaling, gonad function and gender have been shown to influence longevity and stress resistance in the soil nematode, C. elegans. Thus, either of these two processes or gender may influence anoxia survival. The hypothesis that insulin-like signaling alters anoxia survival in C. elegans is tested in Aim I. The hypotheses that gonad function or gender modulates anoxia survival are tested in Aim II. Insulin-like signaling affects anoxia survival in C. elegans. Reduction of insulin-like signaling through mutation of the insulin-like receptor, DAF-2, increases anoxia survival rates in a gpd-2/3 dependent manner. The glycolytic genes gpd-2/3 are necessary for wild-type response to anoxia, and sufficient for increasing anoxia survival through overexpression. Gonad function and gender both affect anoxia survival in C. elegans. A reduction of ovulation and oocyte maturation, as measured by oocyte flux, is associated with enhanced anoxia survival in all cases examined to date. Reduction of function of several genes involved in germline development and RTK/Ras/MAPK signaling reduce ovulation and oocyte maturation while concurrently increasing anoxia survival. The act of mating does not influence anoxia survival, but altering ovulation through breeding or chemical treatment does. The male phenotype also increases anoxia survival rates independent of genotype. These studies have identified and characterized over ten different genotypes that affect adult survival of anoxia in C. elegans. Before these studies were conducted, there were no genes known to influence adult anoxia survival in C. ...
As one of the most remarkable of the Scottish Covenanters, George Gillespie had a reputation in England and Scotland as an orthodox Puritan theologian and apologist for Scottish Presbyterianism. He was well known for his controversial works attacking the ceremonies of the Church of England, defending Presbyterianism, opposing religious toleration, and combating Erastianism. He is best remembered as one of the Scottish Commissioners to the Westminster Assembly in London, which sought to reform the English Church and establish a uniform religion for the two kingdoms. This study assesses his life, ideas, and legacy. In Gillespie's estimation revelation and reason played complementary roles in the Christian life. While the Fall had affected man's reasoning abilities, man could rely upon natural law and scholarship as long as one kept them within the limits of God's truth revealed in Scripture. Moreover, he insisted that the church structure its worship ceremonies, government, and discipline according to the pattern set forth in the Bible. In addition, he emphasized the central role of God's Word and the sacraments in the worship of God and stressed the importance of cultivating personal piety. At the heart of Gillespie's political thought lay the Melvillian theory of the two kingdoms, which led him to reject Erastianism as subordinating the church to the power of the state. Furthermore, his delineation of the limits of the authority of the civil magistrate, presented a challenge to the state's authority and led him to formulate a radical version of the Covenanter doctrine of resistance to the state. While Gillespie supported uniformity of religion between England and Scotland, opposed religious toleration, and rejected the Engagement with King Charles, none of these causes proved successful in his lifetime. Yet these ideas influenced generations of Resolutioners, Protestors, Cameronians, and other heirs of the Scottish Covenanter tradition.
This abstract is for the thesis on the Cathedral of Hope (CoH). The CoH is currently the largest church in the world with a predominantly gay and lesbian congregation. This work tells the history of the church which is located in Dallas, Texas. The thesis employs over 48 sources to help tell the church's rich history which includes a progressive Christian philosophy, an important contribution to the fight for gay civil rights, and fine examples of courage through social activism. This work makes a contribution to gay history as well as civil rights history. It also adds to the cultural and social history which concentrates on the South and Southwestern regions of the United States.
The purpose of the current study was to explore the relationship between cognitive status and depression in a sample of geriatric patients. Participants included 282 geriatric patients ranging in age from 65 to 96 years who were classified according to diagnosis as: DAT, VaD, MCI, and Norm. All were referred for neurocognitive testing from the Geriatric Assessment Program (GAP) at the University of North Texas Health Science Center (UNTHSC) in Fort Worth, Texas. This study sought to identify factor structures for two versions of the GDS using a geriatric sample of cognitively impaired and intact patients. It then compared these factors to each other to determine whether the GDS-15 is truly a shorter version of the GDS-30. These were then compared to a previously determined factor structure. This study explored whether the four-factors of the GDS-30 are able to differentiate cognitive diagnostic groups. Further, this study sought to identify whether the severity of cognitive decline impacted GDS factor score for each of the cognitively impaired groups. Results revealed a two-factor model of the GDS - 15 and a four-factor model with the GDS - 30. The GDS-15 factors did not differ from the first two factors of the GDS-30. Comparison between the GDS-30 factor structure and that reported by Hall and Davis (in press) revealed no significant differences despite the inclusion of a normal, non-demented group in the current study. Comparisons of subscale scores revealed that DAT patients tended to score lower than the other groups on all but the cognitive impairment subscale. Severity level analyses indicated that as severity of deficits increases, awareness of deficits decreases. This study found that although the GDS-30 is a good screening tool for depression in geriatric patients, it is not particularly useful in differentiating cognitive status group. Also, the GDS-15 was not found ...
The purpose of this study was to use the Global Water Stormwater Sampler SS201 to characterize the urban runoff in Pecan Creek. Location of the samplers was influenced by land use and ease of installation. Determination of the constituents for analysis was modeled after those used in the NPDES permit for seven cities within the Dallas/Ft.Worth metroplex. Some metals, notably cadmium and arsenic, exceeded the U.S. EPA's MCL's. Statistical analysis revealed first flush samples to be significantly more concentrated than composite samples. Minimum discharge loadings were found to be significantly lower than maximum discharge loadings. Additionally there were significant differences of specific constituents between station locations and storm events.
Composed for soprano, tenor, and baritone voices, woodwind, percussion, and string instruments, Three Voices is a polyglotic work that includes German, Chinese, and Spanish texts. The texts are chosen from Brecht Bertolt's Das Schiff, Po Chu I's Lang T'ao Sha, and Frederico Garcia Lorcá's Mar. Significant features of the piece are 1) application of Chinese operatic singing methods to vocal material in the sections that use Chinese text, 2) use of western instruments to emulate the sound of certain Chinese instruments, and 3) employment of Sprechstimme and dramatically inflected speech to create theatrical effects and highlight the sections that use German and Spanish texts.
To illustrate the intersection of ethical language and ethical frameworks within technical communication, this dissertation analyzes the history and documentation of the human radiation experiments of the 1940s through the 1970s. Research propositions included clarifying the link between medical documentation and technical communication by reviewing the literature that links the two disciplines from the ancient period to the present; establishing an appropriate historiography for the human radiation experiments by providing a context of the military, political, medical, and rhetorical milieu of the 1940s to the 1970s; closely examining and analyzing actual human radiation experiment documentation, including proposals, letters, memos, and consent forms, looking for established rhetorical constructions that indicate a document adheres to or diverts from specific ethical frameworks; and suggesting the importance of the human radiation documents for studying ethics in technical communication. Close rhetorical analysis of the documents included with this project reveals consistent patterns of metadiscourse, passive and nominal writing styles, and other rhetorical constructions, including negative language, redundancies, hedges, and intensifiers, that could lead a reader to misunderstand the writer's original ethical purpose. Ultimately this project finds that technical communicators cannot classify language itself as ethical or unethical; the language is simply the framework with which the experimenters construct their arguments and communicate their work. Technical communicators can, however, consider the ethical nature of behavior according to specific ethical frameworks and determine whether language contributes to the behavior.
The purpose of this study was to determine the effectiveness of Filial Therapy training in increasing teachers of deaf and hard of hearing preschool students': 1) empathic responsiveness with their students; 2) communication of acceptance to their students; 3) allowance of self-direction by their students. A second purpose was to determine the effectiveness of Filial Therapy training in reducing experimental group students': 1) overall behavior problems; 2) internalizing behaviors; and 3) externalizing behavior problems. Filial Therapy is a didactic/dynamic modality used by play therapists to train parents and teachers to be therapeutic agents with their children and students. Teachers are taught primary child-centered play therapy skills for use with their own students in weekly play sessions with their students. Teachers learn to create a special environment that enhances and strengthens the teacher-student emotional bond by means of which both teacher and child are assisted in personal growth and change. The experimental group (N=24) consisted of 12 teachers, who participated in 11 weekly Filial Therapy training sessions (22 total instructional hours) during the fall semester at the preschool of a center for communications disorders, and 12 students chosen by the teachers as their student of focus. Teachers and students met once a week during the training for 30 minute teacher student play sessions in a room specified for this purpose. The non-treatment comparison group received no training during the 11 weeks. Teacher participants completed two written instruments: the Child Behavior Checklist/Caregiver-Teacher Report Form and the Meadow-Kendall Social-Emotional Assessment Inventory for Deaf and Hearing Impaired Students. Teachers who received Filial Therapy training were videotaped during student teacher play sessions. The videotaped sessions were used for pretest and posttest evaluation for the Measurement of Empathy in Adult-Child Interaction. Analysis of covariance revealed the children in the experimental group significantly decreased overall behavior problems. ...
This study was designed to determine the effectiveness of a filial/play therapy training model with high school juniors and seniors enrolled in a Peer Assistance and Leadership program (PALs). Filial/play therapy is an intervention that focuses on strengthening and enhancing adult-child relationships. The high students are trained to be a therapeutic change agent for primary school children identified as having adjustment difficulties by utilizing basic child-centered play therapy skills in weekly play sessions with young children. Specifically, this study is designed to determine the effectiveness of filial therapy in increasing: 1) the high school students' observed empathic behavior with young children, 2) the high school students' observed attitude of acceptance toward young children, 3) the high school students' observed ability to allow self-direction in young children, and 4) the high school students' observed level of involvement with young children. The experimental group, consisting of 16 volunteer high school students enrolled in a PALs class for high school credit, received a total of 24 weeks of filial/play therapy didactic training, application, and supervision for the playtimes they conducted with pre-kindergarten/kindergarten students identified with adjustment difficulties. The comparison group consisted of 15 volunteer high school students enrolled in a PALs class for high school credit. The comparison group received the standard PALs class curriculum. All students were videotaped playing with a young child 4 to 6 years of age before and after the training as a means of measuring empathic behavior with young children. An Analysis of Covariance revealed statistically significant findings in all four hypotheses. Specifically, the experimental group of high school students exhibited statistically significant increases in empathic interactions with young children when compared to the comparison group. The experimental group also exhibited statistically significant increases in communication of acceptance of young children's feelings and behaviors, acceptance and behavioral willingness ...
The Electoral College and Jacksonian Democracy are two subjects that have been studied extensively. Taken together, however, little has been written on how the method of choosing presidential electors during the Age of Jackson changed. Although many historians have written on the development of political parties and the increase in voter participation during this time, none have focused on how politicians sought to use the method of selecting electors to further party development in the country. Between 1824 and 1832 twelve states changed their methods of choosing electors. In almost every case, the reason for changing methods was largely political but was promoted in terms of advancing democracy. A careful study of the movement toward selecting electors on a general ticket shows that political considerations in terms of party and/or state power were much more important than promoting democratic ideals. Despite the presence of a few true reformers who consistently pushed for a constitutional amendment guaranteeing that all states used the same method, the conclusion must be that politics and party demanded a change. This study relies heavily on legislative records at both the state and national level and newspapers throughout t the country from the period. Beginning with a brief history of the office of the president and an overview of the presidential elections prior to 1824, the author then carefully analyzes the elections of 1824, 1828, and 1832, as well as the various efforts to amend the constitutional provisions dealing with the Electoral College. Particular emphasis is placed on political factions at the state level, the development of the Democratic and National Republican parties nationally, and how each party used and at time manipulated the electoral process to secure a favorable outcome for their candidates.
This thesis examines the history of the Greater Dallas Crime Commission and its effectiveness within the criminal justice system. It is a private agency established fifty (50) years ago to monitor and investigate the criminal justice system. Today, it serves as a source of funding for criminal justice agencies, provides awards and recognition forums for law enforcement and lobbies for legal revisions of the criminal code. The research is designed to examine their role within the criminal justice system. Whether current crime theories are supported by the commission is central to the thesis. There are no prior studies available of crime commissions perhaps because they are privately funded and operated by civilians. Crime commissions do exert influence, politically and financially, upon law enforcement. It is reflected often in their history. The extent of this effect is the subject of the paper. To this end, the commission's role in changing state laws, providing funds for police training, recognizing prosecutors and paying awards to informants lends credibility to their role in the criminal justice system. Their function has often changed during the fifty-year history. If there is a deficit, it may be that the commission has the capability, through its sphere of influence, of encouraging civilian actions that may conflict with law enforcement policy. Some examples of these are included in the study.
A 1H, 13C, and 6Li NMR study of 2-ethyl-1-butyllithium indicated that 2-ethyl-1-butyllithium exists only as a hexameric aggregate over the entire temperature range of 25 to - 92.1 ° C in cyclopentane. Reacting 2-ethyl-1-butyllithium with 2-ethyl-1-butanol resulted in alkyllithium/lithium alkoxide mixed aggregates, apparently of the form Ra(RO)bLia+b. A multinuclear, variable temperature NMR study of samples with O:Li ratios of 0.2 and 0.4 showed, in addition to the alkyllithium, the formation of four mixed aggregates, one of them probably an octamer. Higher O:Li ratio samples showed the formation of several other mixed aggregates. Mixing 2-ethyl-1-butyllithium with independently prepared lithium 2-ethyl-1-butoxide formed the same mixed aggregates formed by in situ synthesis of lithium alkoxide. Lithium 2-ethyl-1-butoxide also exists as aggregates in cyclopentane.
This research focuses on the association between law enforcement training and implementation of hate crime legislation. The Anti-Defamation League's state hate crime statutory provisions and the Federal Bureau of Investigation's Hate Crime Reporting by States data are examined. Section one includes the following: What Constitutes Hate?, The History of Hate Crime Legislation, and Issues Facing Hate Crime Legislation. Section two surveys literature on both Hate Crime Legislation and the training of law enforcement officers. Section three discusses the Anti-Defamation League and FBI data in detail and explains the methods used to test the association between law enforcement training and reporting of hate crime legislation. Findings yield a statistically significant association between law enforcement training and reporting of hate crime legislation.
The oboe, which first came into being in the middle of the seventeenth century in France, underwent a number of changes throughout the following century. French instruments were influenced both by local practices and by the introduction of influences from other parts of Europe. The background of the makers of these instruments as well as the physical properties of the oboes help to illuminate the development of the instrument during this period. The examination of measurements, technical drawings, photographs, and biographical data clarify the development and dissemination of practices in oboe building throughout eighteenth-century France. This clarification provides new insight into a critical period of oboe development which has hitherto not been exclusively addressed.
Aggression in dogs is a significant public health concern with 7.2 mortality cases per 100 million inhabitants and approximately 4.7 million dog bites annually. Canine aggression is typically viewed as a genetic trait and treated as pathology through the use of medical or respondent behavioral procedures. In this study the effects of the differential negative reinforcement of safe, alternative behaviors to aggression using distancing as the reinforcer were evaluated. The results demonstrated that even when the aggression was in evidence throughout most of the dog's lifetime, it responded quickly to changes in reinforcement contingencies.
This dissertation chronicles my search to engage high school English students in inquiry as part of a formal research process. The perspective of critical literacy theory is used to describe the four phases of the problem posing process in shaping student research and action. Grounded in Freire's approach and consistent with Dewey and others who advocate inquiry, action and relevance, Wink's process is built into the instructional plan described in this study. Because of the real-life context of the classroom and the complex social phenomena being considered, a case study methodology was utilized in which multiple sources of data converged to develop the themes. Data sources included the work and artifacts of ten students in a tenth grade English class during the spring semester of 2008. The analysis focuses on the supports, the constraints and the impact of problem posing on the high school research assignment. The analysis, findings, and conclusions contribute to the literature in three areas: audience, reflection and grading.
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 the learning objectives identified and individual student needs.
This study examined the consistency between verbal responses to hypothetical conflict scenarios and the actual conflict resolutions techniques children apply in everyday play. Twenty-one children were interviewed and observed in order to determine their conflict resolution strategies. During the interview process, each child was asked to finish 6 hypothetical conflict scenarios. During the observation portion, each child was observed in 2 conflict scenarios. Significant (p < .05) differences were found with regards to verbal responses for 3 scenarios, verbal and behavioral responses of females (females exhibited more socially acceptable conflict resolution strategies in their verbal responses, yet less socially acceptable conflict resolution strategies in their behavioral responses), and socially acceptable responses to conflict in verbal strategies. Results were discussed in light of previous research comparing gender differences and peer relationships to conflict resolution strategies.
Symmetry suppression was conducted for five subjects who demonstrated a tendency to derive equivalence relations based on conditional discrimination training in a match-to-sample procedure. Symmetry suppression was applied in three consecutive sessions in which symmetrical responses were suppressed for one stimulus class in the first condition, two stimulus classes in the second condition, and all three stimulus classes in the final condition. Symmetry suppression slowed the emergence of transitivity for two subjects and prevented it for the other three. Results indicated that unplanned features of stimulus configurations emerged as discriminative variables that controlled selection responses and altered the function of consequent stimuli. Disruption of cognitive development by conflicting contingencies in natural learning environments is discussed.
The pilot study used in this thesis examined the attitudes and perceptions of a small group of students at the University of North Texas. The participants in this pilot study (n=22) were administered an online music file sharing survey, a Defining Issues Test (DIT), and participated in a small focus group. This thesis also outlined the history and progression of online music piracy in the United States, and addressed four research questions which aimed to determine why individuals choose to engage in the file sharing of copyrighted music online.
Terrorism is a historical problem; however, it becomes one of the biggest problems in 21st century. September 11 and the following Madrid, Istanbul and London attacks showed that it is the most significant problem threatening world peace and security. Governments have started to deal with terrorism by improving security measurements and making new investments to stop terrorism. Most of the governments' and scholars' focus is on immediate threats and causes of terrorism, instead of looking at long-term solutions such as root causes and underlying reasons of terrorism, and the recruitment style of terrorist organizations If terrorist recruitment does not stop, then it is safe to say terrorist activities cannot be stopped. This study focused on the recruitment process by observing two different terrorist organizations, DHKP/C and Turkish Hezbollah. The researcher brings 13 years of field experience and first-person data gathered from inside the terrorist organizations. The research questions of this study were: (i) How can an individual be prevented from joining or carrying out terrorist activities?; (ii) What factors are correlated with joining a terrorist organization?; (iii) What are the recruitment processes of the DHKP/C, PKK, and Turkish Hezbollah?; (iv) Is there any common process of being a member of these three terrorist organizations?; and (v) What are the similarities and differences these terrorist organizations? As a result of this analysis, a terrorist recruitment process map was created. With the help of this map, social organizations such as family and schools may be able to identify ways to prevent individuals from joining terrorist organizations. Also, this map will also be helpful for government organizations such as counterterrorism and intelligence to achieve the same goal.
Media sociologists have produced much research on the systems of production of media content. Photojournalism, however, largely has been ignored in these studies. This paper presents the findings of an ethnographic study of work routines and photojournalism practices at three newspapers. The study explored the extent to which routines and practices are affected by professional norms and values and organizational needs and beliefs. The study also explored how these factors influence the content and aesthetic qualities of newspaper photographs. Findings suggest that photo editors and photojournalists operate under many of the same constraints as other media workers. The findings also show that photojournalists are socialized to newspapers. expectations by fellow photographers and photo editors. To gauge professional accomplishments, photojournalists rely on peers, professional organizations and competitions.
In a world that is increasingly united in time and distance, I examine why the world is increasingly divided socially, economically, and digitally. Using data for 35 variables from 93 countries, I separate the countries into groups of 31 each by gross domestic product per capita. These groups of developed, lesser developed and least developed countries are used in comparative analysis. Through a review of relevant literature and tests of bivariate correlation, I select eight key variables that are significantly related to information communication technology development and to human development. For this research, adoption of the Internet in the developing world is the innovation of particular interest. Thus, for comparative purposes, I chose Internet Users per 1000 persons per country and the Human Development Index as the dependent variables upon which the independent variables are regressed. Although small in numbers among the least developed countries, I find Internet Users as the most powerful influence on human development for the poorest countries. The research focuses on key obstacles as well as variables of opportunity for Internet usage in developing countries. The greatest obstacles are in fact related to Internet availability and the cost/need ratio for infrastructure expansion. However, innovations for expanded Internet usage in developing countries are expected to show positive results for increased Internet usage, as well as for greater human development and human capital. In addition to the diffusion of innovations in terms of the Internet, the diffusion of cultures through migration is also discussed in terms of the effect on social capital and the drain on human capital from developing countries.
Supply chain management (SCM) is an area that offers organizations significant opportunities for both cost reductions and revenue enhancement. In their article, "Supply Chain Management: Implementation Issues and Research Opportunities," Lambert, Cooper and Pagh defined SCM as the "integration of key business processes from end user through original suppliers that provides products, services, and information that add value for customers and other stakeholders." Adopting and implementing appropriate technology has emerged as a source of competitive advantage for supply chain member firms through the integration of business processes with suppliers and customers. It is important to understand the factors influencing an organization's decision to acquire such technology. In the context of this study, connective technologies are defined as wireless communication devices and their accompanying infrastructure and software which may enhance coordination among supply chain partners. Building on previous literature in the areas of supply chain management, marketing strategy, and organizational innovation, a model was developed to test the relationships between organizational, interorganizational, and technology-related factors and the adoption of advanced connective technology, using radio frequency identification (RFID) as the test case, in the supply chain. A Web-based survey of supply chain professionals was conducted resulting in 224 usable responses. The overall model was statistically significant with four of the predictors significantly influencing the adoption of RFID in the supply chain. Size, centralization, new product advantage and time to achieve targeted ROI were significantly related to adoption of connective technology (RFID). Interorganizational related factors were not significant predictors of connective technology adoption. The study contributes to theory by testing scales from marketing and management in a supply chain context in order to better understand behavioral dimensions of supply chain management and logistics. The conceptualization and measurement of market orientation at the interfirm level advances the market orientation literature. Finally, the study contributes ...
This dissertation addresses the delicate problem of establishing the statistical mechanical foundation of complex processes. These processes are characterized by a delicate balance of randomness and order, and a correct paradigm for them seems to be the concept of sporadic randomness. First of all, we have studied if it is possible to establish a foundation of these processes on the basis of a generalized version of thermodynamics, of non-extensive nature. A detailed account of this attempt is reported in Ignaccolo and Grigolini (2001), which shows that this approach leads to inconsistencies. It is shown that there is no need to generalize the Kolmogorov-Sinai entropy by means of a non-extensive indicator, and that the anomaly of these processes does not rest on their non-extensive nature, but rather in the fact that the process of transition from dynamics to thermodynamics, this being still extensive, occurs in an exceptionally extended time scale. Even, when the invariant distribution exists, the time necessary to reach the thermodynamic scaling regime is infinite. In the case where no invariant distribution exists, the complex system lives forever in a condition intermediate between dynamics and thermodynamics. This discovery has made it possible to create a new method of analysis of non-stationary time series which is currently applied to problems of sociological and physiological interest.
Computational techniques were employed to investigate pathways that would improve the properties and characteristics of transition metal (i.e., ruthenium) catalysts, and to explore their mechanisms. The studied catalytic pathways are particularly relevant to catalytic hydroarylation of olefins. These processes involved the +2 to +3 oxidation of ruthenium and its effect on ruthenium-carbon bond strengths, carbon-hydrogen bond activation by 1,2-addition/reductive elimination pathways appropriate to catalytic hydrogen/deuterium exchange, and the possible intermediacy of highly coordinatively unsaturated (e.g., 14-electron) ruthenium complexes in catalysis. The calculations indicate a significant decrease in the Ru-CH3 homolytic bond dissociation enthalpy for the oxidation of TpRu(CO)(NCMe)(Me) to its RuIII cation through both reactant destabilization and product stabilization. This oxidation can thus lead to the olefin polymerization observed by Gunnoe and coworkers, since weak RuIII-C bonds would afford quick access to alkyl radical species. Calculations support the experimental proposal of a mechanism for catalytic hydrogen/deuterium exchange by a RuII-OH catalyst. Furthermore, calculational investigations reveal a probable pathway for the activation of C-H bonds that involves phosphine loss, 1,2-addition to the Ru-OH bond and then reversal of these steps with deuterium to incorporate it into the substrate. The presented results offer the indication for the net addition of aromatic C-H bonds across a RuII-OH bond in a process that although thermodynamically unfavorable is kinetically accessible. Calculations support experimental proposals as to the possibility of binding of weakly coordinating ligands such as dinitrogen, methylene chloride and fluorobenzene to the "14-electron" complex [(PCP)Ru(CO)]+ in preference to the formation of agostic Ru-H-C interactions. Reactions of [(PCP)Ru(CO)(1-ClCH2Cl)][BAr'4] with N2CHPh or phenylacetylene yielded conversions that are exothermic to both terminal carbenes and vinylidenes, respectively, and then bridging isomers of these by C-C bond formation resulting from insertion into the Ru-Cipso bond of the phenyl ring of PCP. The QM/MM and DFT calculations on full complexes ...
In this research, a security architecture based on the feedback control theory has been proposed. The first loop has been designed, developed and tested. The architecture proposes a feedback model with many controllers located at different stages of network. The controller at each stage gives feedback to the one at higher level and a decision about network security is taken. The first loop implemented in this thesis detects one important anomaly of virus attack, rate of outgoing connection. Though there are other anomalies of a virus attack, rate of outgoing connection is an important one to contain the spread. Based on the feedback model, this symptom is fed back and a state model using queuing theory is developed to delay the connections and slow down the rate of outgoing connections. Upon implementation of this model, whenever an infected machine tries to make connections at a speed not considered safe, the controller kicks in and sends those connections to a delay queue. Because of delaying connections, rate of outgoing connections decrease. Also because of delaying, many connections timeout and get dropped, reducing the spread. PID controller is implemented to decide the number of connections going to safe or suspected queue. Multiple controllers can be implemented to control the parameters like delay and timeout. Control theory analysis is performed on the system to test for stability, controllability, observability. Sensitivity analysis is done to find out the sensitivity of the controller to the delay parameter. The first loop implemented gives feedback to the architecture proposed about symptoms of an attack at the node level. A controller needs to be developed to receive information from different controllers and decision about quarantining needs to be made. This research gives the basic information needed for the controller about what is going on at individual nodes of ...
Kurt Vonnegut's early science fiction novels depict societies and characters that, as in the real world, have become callous and downtrodden. These works use supercomputers, aliens, and space travel, often in a comical manner, to demonstrate that the future, unless people change their concepts of humanity, will not be the paradise of advanced technology and human harmony that some may expect. In fact, Vonnegut suggests that the human condition may gradually worsen if people continue to look further and further into the universe for happiness and purpose. To Vonnegut, the key to happiness is dignity, and this key is to be found within ourselves, not without.
