This exploratory study examines documentation practices and processes in ten small non-profit organizations. The objectives of this study were to answer the following two research questions: (1) What organizational needs do small non-profit organizations have that are relevant to technical communication? and (2) How are small 501(c)(3) organizations attempting to meet these needs? Which of these attempted solutions are ineffective? Semi-structured interviews were conducted with two people from each organization: the executive director and a volunteer. Interviews were transcribed and analyzed, and grounded theory was used to identify coding categories related to documentation development. Primary findings suggest that interviewees are aware that they need documentation, yet they often postpone developing such documentation until problems develop. The study findings also suggest that interviewees across different nonprofit organizations value documentation for similar reasons. Strategies are provided for technical communicators interested in working with nonprofit organizations, and additional research avenues are identified.

Condensation of 2,3-dichloromaleic anhydride and o-phenylenediamine in refluxing toluene affords the three compounds 2,3-dichloro-N-o-C6H4(NH2)maleimide (1), N,N¢-o-C6H4-bis(2,3-dichloromaleimide) (2), and 2,3-dichloropyrrolo[1,2-a]benzimidazol-1-one (3), with compound 1 as the major product. Repeating the same reaction in the presence of added PTSA furnishes compound 3 as the major product. Treatment of 3 with methylthiol in the presence of pyridine affords monosulfide compounds 2-chloro-3-methylthiopyrrolo[1,2-a]benzimidazol-1-one (4) and and the disulfide derivatives 2,3-di(methylthio)pyrrolo[1,2-a]benzimidazol-1-one (5). The substitution of the first chlorine group in compound 3 occurs regioselectively at C-3 to produce compound 4, followed by replacement of the remaining chlorine group to furnish the disulfide compounds 5. The new compounds 1-5 have been isolated by column chromatography and characterized by IR, NMR, XRD, CV and etc.

The goal of this thesis is to study of the evolution of 3D electrically charged liquid droplets of fluid evolving under the influence of surface tension and electrostatic forces. In the first part of the thesis, an appropriate mathematical model of the problem is introduced and the linear stability analysis is developed by perturbing a sphere with spherical harmonics. In the second part, the numerical solution of the problem is described with the use of the boundary elements method (BEM) on an adaptive mesh of triangular elements. The numerical method is validated by comparison with exact solutions. Finally, various numerical results are presented. These include neck formation in droplets, the evolution of surfaces with holes, singularity formation on droplets with various symmetries and numerical evidence that oblate spheroids are unstable.

The purpose of dissertation is to utilize connotative messages for enhancing image retrieval and browsing. By adopting semiotics as a theoretical tool, this study explores problems of image retrieval and proposes an image retrieval model. The semiotics approach conceptually demonstrates that: 1) a fundamental reason for the dissonance between retrieved images and user needs is representation of connotative messages, and 2) the image retrieval model which makes use of denotative index terms is able to facilitate users to browse connotatively related images effectively even when the users' needs are potentially expressed in the form of denotative query. Two experiments are performed for verifying the semiotic-based image retrieval model and evaluating the effectiveness of the model. As data sources, 5,199 records are collected from Artefacts Canada: Humanities by Canadian Heritage Information Network, and the candidate terms of connotation and denotation are extracted from Art & Architecture Thesaurus. The first experiment, by applying term association measures, verifies that the connotative messages of an image can be derived from denotative messages of the image. The second experiment reveals that the association thesaurus which is constructed based on the associations between connotation and denotation facilitates assigning connotative terms to image documents. In addition, the …

In the essay A Rhetorical Guide to Ebb I explore the diverse array of influences in art, and music that guided the creation of the composition Ebb, for 13 musicians and electronics. Of those influences, the boxes of the American artist Joseph Cornell played a particularly important role. Having based the conceptual framework for Ebb on ideas taken from Cornell, the essay, instead of being driven by a single thesis, involves the creation of conceptual boxes. These conceptual boxes emphasize the influence of the artist Joseph Cornell, along with the composers Iannis Xenakis and Gérard Grisey. In addition, a time line documenting the stages in Ebb's creation is included.

The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences between the proximal and distal portions of the DA with regard to lumen occlusion, endothelial cells, smooth muscle and elastin. Endothelial cell proliferation begins to occur as early as external pipping, with the lumen almost completely occluded by the 3rd day of post-hatching life. Expression of vascular endothelial growth factor (VEGF) increases in avian endothelial cells during hatching. I provide a morphological timeline of changes in the DA as the chicken develops from embryo to hatchling.

According to Alexis de Tocqueville, humanity is entering a new age of political and social equality, a new epoch in which the human race has no historical example or experience. As a result, he holds humanity's future will be largely determined by the political and moral choices made in this transitional time. For Tocqueville, the new egalitarian era is a forgone conclusion, but for him, the pressing question is whether humanity will choose a future in which it enchains itself to new forms of tyranny, or, whether the human race can establish the political and moral institutions designed to assure human freedom and dignity. In Tocqueville's view, liberty or slavery are the two choices modern men and women have in front of them, and it is the intent of this dissertation to explore Tocqueville's warning in regard to the latter choice. Tocqueville warns us that modern democratic peoples must beware of the moral and political effects of a new type of political philosophy, a political theory he terms democratic pantheism. Democratic pantheism is a philosophic doctrine that treats egalitarianism as a "religion" in which all social and political striving is directed toward realizing a providentially ordained strict equality of conditions. …

The Iwahori-Hecke algebras of Coxeter groups play a central role in the study of representations of semisimple Lie-type groups. An important tool is the combinatorial approach to representations of Iwahori-Hecke algebras introduced by Kazhdan and Lusztig in 1979. In this dissertation, I discuss a generalization of the Iwahori-Hecke algebra of the symmetric group that is instead based on the complex reflection group G(r,1,n). Using the analogues of Kazhdan and Lusztig's R-polynomials, I show that this algebra determines a partial order on G(r,1,n) that generalizes the Chevalley-Bruhat order on the symmetric group. I also consider possible analogues of Kazhdan-Lusztig polynomials.

Partial order planning is an important approach that solves planning problems without completely specifying the orderings between the actions in the plan. This property provides greater flexibility in executing plans; hence making the partial order planners a preferred choice over other planning methodologies. However, in order to find partially ordered plans, partial order planners perform a search in plan space rather than in space of world states and an uninformed search in plan space leads to poor efficiency. In this thesis, I discuss applying a reinforcement learning method, called First-visit Monte Carlo method, to partial order planning in order to design agents which do not need any training data or heuristics but are still able to make informed decisions in plan space based on experience. Communicating effectively with the agent is crucial in reinforcement learning. I address how this task was accomplished in plan space and the results from an evaluation of a blocks world test bed.

I start writing by conjuring up an image in my mind. Sometimes it will be something that I have thought about for a while, sometimes it will be something that I sit around attempting to create. Either way, it is simply the idea that I need in order to get started. People will say, "Just sit down and write" which I can do, but it does not mean I will end up anywhere worthwhile. In my writing I need a focus. I need an idea or just one image to get me writing and I can base an entire story off of that one image. I think the reason this works for me is because in my mind it is an illustration and always something that is vibrant and unique. I want the image to stand out and to mean something because I feel that it comes to me for a specific reason, I just have to piece it all together and let the characters and plot unfold for themselves. People often say this, that the characters end up running the story. I think this is true, but in my case my stories are not so driven by character or …

This dissertation is a study of morale in the western Confederacy from early 1864 until the Civil War's end in spring 1865. It examines when and why Confederate morale, military and civilian, changed in three important western states, Mississippi, Alabama, and Tennessee. Focusing on that time frame allows a thorough examination of the sources, increases the opportunity to produce representative results, and permits an assessment of the lingering question of when and why most Confederates recognized, or admitted, defeat. Most western Confederate men and women struggled for their ultimate goal of southern independence until Federal armies crushed those aspirations on the battlefield. Until the destruction of the Army of Tennessee at Franklin and Nashville, most western Confederates still hoped for victory and believed it at least possible. Until the end they drew inspiration from battlefield developments, but also from their families, communities, comrades in arms, the sacrifices already endured, simple hatred for northerners, and frequently from anxiety for what a Federal victory might mean to their lives. Wartime diaries and letters of western Confederates serve as the principal sources. The dissertation relies on what those men and women wrote about during the war - military, political, social, or otherwise - …

The purpose of this study was to examine and document second language teachers' perceptions of their implementation of a meaning-making approach, known as the Acquisition Model, to second language instruction. Of particular focus were the concerns and strategies the second language teachers experienced when changing their pedagogical practice from mechanical to meaning making. The main research question, which guided this study, was: "What is the 'lived experience' of L2 teachers as they implement an innovative pedagogy to teach a second language?" The researcher addressed this research question through Max van Manen's (1990) six step phenomenological method, "Researching Lived Experience" and image-based research techniques (i.e., photo elicitation and reflexive photography). In addition, the researcher also created and applied an innovative data collection technique, which she called Collaborative Imagery. Findings from this study generated various implications in the areas of second language education, curricular change, teacher reflection, image-based research, and educational research.

While literature in areas of constructivism learning theory, use of computer technology in education, and the implementation of project-based learning in the classroom have received widespread attention, there is no reported research that specifically examines the effectiveness of using a project-based learning model for computer technology instruction for pre-service teachers' programs in general, and in art education in particular. Thus, the research problem was to examine through pre- and post-test control-group experimental research design whether two different teaching methods, constructivism teaching approach (project-based learning) and traditional (step-by-step) teaching approach, result in significant differences in learning computer usage, the application of computer technical skills, design projects, and attitudes toward using of technology. The research was conducted at University of North Texas during the fall semester of 2004. Both quantitative and qualitative methods were used to collect the data. The quantitative data, collected from a pre-post test and pre and post questionnaire, was analyzed using a t-test. No significant difference was found between the groups as it relates to computer usage, one aspect of the application of computer technical skills (Photoshop usage), and attitudes towards technology. There was, however, a statistical difference between the groups in the use of the other aspect …

This study sought to answer if the Home Instruction for Parents of Preschool Youngsters (HIPPY) program had a positive academic impact on Hispanic English language learners (ELL). HIPPY is a free, 2-year, home-based early intervention program for 4-and 5-year-old children. The program is intended to provide educational enrichment to at-risk children from poor and immigrant families, increase school readiness, and foster parent involvement in their children's education. A quasi-experimental design and quantitative measures were used to measure the academic success of Hispanic ELL students in reading, mathematics, and language arts. The sample included an experimental group and a purposeful control group. Hispanic students who attended an early childhood school as 4 year olds and participated in the HIPPY 4 and 5 programs were compared to Hispanic students who attended an early childhood school as 4 year olds and did not participate in HIPPY. Results from the Texas-mandated criterion referenced Texas Assessment Knowledge and Skills (TAKS™) Test and the TerraNova® and TerraNova SUPERA® norm referenced tests were used in this study. Results from the TAKS Reading and TAKS Mathematics Grade 3 and the TerraNova reading, language, mathematics, and total composite scores were analyzed using a one-way analysis of variance. The treatment …

In this dissertation we study graph directed Markov systems (GDMS) and limit sets associated with these systems. Given a GDMS S, by the Hausdorff dimension spectrum of S we mean the set of all positive real numbers which are the Hausdorff dimension of the limit set generated by a subsystem of S. We say that S has full Hausdorff dimension spectrum (full HD spectrum), if the dimension spectrum is the interval [0, h], where h is the Hausdorff dimension of the limit set of S. We give necessary conditions for a finitely primitive conformal GDMS to have full HD spectrum. A GDMS is said to be regular if the Hausdorff dimension of its limit set is also the zero of the topological pressure function. We show that every number in the Hausdorff dimension spectrum is the Hausdorff dimension of a regular subsystem. In the particular case of a conformal iterated function system we show that the Hausdorff dimension spectrum is compact. We introduce several new systems: the nearest integer GDMS, the Gauss-like continued fraction system, and the Renyi-like continued fraction system. We prove that these systems have full HD spectrum. A special attention is given to the backward continued fraction …

For most of the past century, the positive outcome of grief in the West was characterized as the relinquishment of the bond to the deceased. Phrases such as "let go", "move on", and "get over it" were, and continue to be, common to the language of this pursuit. This 'breaking bonds' perspective does not take into account other means of grief resolution, nor does it consider historical or cultural findings. Consequently, reports of bereaved parents who indicate resolution of grief yet maintain a continued relationship with their deceased child were not given much attention until the 1990s. This research employed a Durkheimian approach, taking the social bond as the starting point of inquiry and examined continuing bonds of parents to their murdered children. How these bonds were related to the parents' attitudes of re-investing in life and their level of grief was measured. The relationship between the parents' level of grief and their life attitudes was also assessed. The sample consisted of 46 parents living in North Texas whose child had been murdered three or more years ago. A triangulated methodology was utilized and the data were collected by means of participant observation, unstructured interviews, and a mailed questionnaire which …

This study examines occupational aspiration and choice of traditional first-time college students utilizing longitudinal data from the Cooperative Institutional Research Program (CIRP). Focus is given to beliefs about the importance of family and money in relation to selection of an occupation that is classified as sex-typed. Change from one occupational category to another is also considered. The dissonance between students' beliefs about the importance of family and money as associated with their sex-typed occupational choice is explored. Understanding students' occupational plans that subsequently determine future prestige, wealth, and status is vital to higher educational professionals who facilitate students in their career selection and major. Therefore, environmental factors of satisfaction with career counseling and academic advising are examined. The U.S. Census Equal Employment Opportunity (EEO) data is applied in the classification of sex-typed occupations. Race and ethnicity is investigated to determine if the same gender patterns exist among cultural groups with regards to their occupational selection. The results indicate that students' occupational aspirations were influenced by their belief regarding the importance of family or money. In addition, their beliefs regarding family and money changed after four years of college with family increasing in importance. Strong beliefs that were, either concordant or …

Objective: Differences between biologic and non-biologic parents' acceptance and use of ordinary corporal punishment and use of explaining/reasoning as a disciplinary tool are examined from a sociobiological theoretical perspective. Method: Cross tabulations are used on data from a national survey conducted by the Gallup Organization in 1995. Results: Contrary to predictions, differences between biologic and non-biologic parents' acceptance of ordinary corporal punishment and the use of explaining/reasoning are not statistically significant. In addition, biologic parents are found to use ordinary corporal punishment significantly more often than non-biologic parents. Conclusions: The sociobiological theoretical perspective likely underestimates the influence of culture and social structure on parent-child interactions.

The purpose of this study was to determine the effectiveness of and the subjects' overall satisfaction with the implementation of an internally created performance appraisal system. The system was implemented at a major technology consulting firm in the US. The subjects of this study were manager level employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of managers' responses to six key questions in the Career Development category were analyzed. Managers' perceptions of their contribution to the firm, their understanding of what career paths are available to them, their understanding of the requirements for promotion, as well as their overall satisfaction with the implementation of the performance appraisal system were captured by this survey. Trend analysis indicates that managers at the firm perceived their career path knowledge improved and their understanding of promotion criteria improved as a result of the implementation. Overall satisfaction with the implementation did not improve enough to site confidence in managers' perceptions for the period immediately after the implementation; managers' responses to the actual implementation were disagreeable to neutral. Managers did not feel their impact on the organization improved as …

Educators can no longer simply look at student totals to distribute instructional dollars. Databased decision-making must be instituted to overcome achievement gaps between white and non-white students. In low-socioeconomic (SES) settings, districts must increase expenditure per pupil (EPP) as low-SES rates rise for all students as district administrators must be in a position to show product rather than process. It was attempted to determine if a positive or negative relationship existed between Anglo, Hispanic, and African-American student test scores and wealth factors on the Texas Assessment of Academic Skills tests in 2000 and 2002. Wealth factors studied included EPP and SES. Data analysis was carried out on 974 independent and consolidated school districts in Texas. Low-SES was found to be a negative predictor of higher test performance on standardized reading and mathematics tests. To varied degrees, low-SES affected all students from all ethnicities as well as affluent students. EPP was attributed with a positive effect on student test performance. Increases of $1,000 or more at one time produce performance increases from 0.20 to 0.40 points. In making specific recommendations, the researcher advises increasing expenditures low-SES districts, schools, and classrooms through the creation of specific district linear equations exhibited in this …

Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better …

Johann Sebastian Bach's chorale preludes are varied and artistic not only in the treatment of chorale melodies, but also in the accompaniments of those chorale melodies. This study examines the accompaniments of Bach's long chorale preludes, focusing on identifying the various types and the characteristics that make them unique. This study investigates the two broad categories of accompaniments depending on whether the motives are chorale-derived or independent of the chorale. While the chorale prelude accompaniments in the first large group are closely related, the accompaniments of the chorale preludes in the second group stand independently and illustrate the vast range of Bach's compositional skill. Both groups demonstrate Bach's interest in expanding his predecessors' models, a trait that can be traced throughout all of Bach's compositional history.

This creative thesis is comprised of five original short stories and a critical preface. The preface discusses the changing cultural, sociopolitical, and socioeconomic landscape of the modern American South and the effects-positive, negative, and neutral-these changes have had on the region's contemporary literature, including the short stories contained within.

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 …
