The Role of Information Technology Support Mechanisms in Coordination Management for Virtual Teams
The purpose of this research is to examine virtual team members' use and perceptions of information technology (IT) support mechanisms. The study identifies the IT support mechanisms currently in use and focuses on differences between virtual and non-virtual teams in control and coordination, IT acceptance, and IT adoption.
Social Validation of Intervention Procedures for Emotionally Disturbed Students : Effects on Regular Education Students
The purpose of this study was to explore regular education student perceptions of the effects of implementing behavioral interventions for seriously emotionally disturbed students (SED) in the regular classroom. Student perceptions of classroom friction or disruptiveness, apathy, and general enjoyment or satisfaction were evaluated. It was predicted that regular education students would report more classroom friction, increased apathy, and less satisfaction when interventions were implemented in the regular classroom for a target SED student.
A Study of the Effects of Using Complete Hypertext Compared with the Effects of Using Focused Hypertext in the Delivery of Computer Based Instruction
The purpose of the study was to examine the impact that hypertext and hypertext design on the cognitive process. The study used two identical computer based lessons. One set of lessons used a complete set of hypertext resources that supported all of the learning objectives throughout the lessons. The other set of lessons focused the hypertext resources by limiting them to the immediate learning objective.
A Study of the Relationships among Teachers' Immediacy of Dress Factors and Affective Learning Factors: a Relational Communication Perspective
This thesis examined the relationships among immediacy of dress factors and affective learning factors as they pertain to relational communication. College students (N = 482) completed questionnaires indicating perceptions of selected nonverbal immediacy behaviors associated with their teacher's attire. The research predicted that there would be relationships between and among power and affinity of dress, dress immediacy and nonverbal immediacy. Further predictions were made concerning the associations among these variables, affective learning outcomes, and other teacher criteria. Analysis indicated that power of dress, affinity of dress and dress immediacy were viable nonverbal immediacy concepts which related to affective learning outcomes. Research findings indicated that certain instructor variables may also influence these relationships.
Susceptibility of College Students to Alcohol Abuse and Alcohol Related Problems: the Impact of Family Environmental Factors
The purpose of this study was to examine the impact of parental divorce, level of family conflict, and family history of alcoholism on the alcohol use patterns of college students. Gender differences were also explored. Multivariate Analysis of Variance revealed mixed results. Parental marital status was found to have no significant effect on college students' alcohol behavior. High family conflict had a significant impact on both level of current alcohol use and level of alcohol related problems. A positive family history of alcoholism was found to have effects on the level of alcohol related problems encountered by students. Gender played a significant role, with males reporting higher levels of alcohol-related problems. No significant interactions were found. Results, contributions and limitations of the study are discussed.
Transcendentalism and Intertextuality in Charles Ives's War Songs of 1917
This thesis examines a collection of three songs, "In Flanders Fields," "He Is There!," and "Tom Sails Away," written by Charles Ives in 1917, from primarily a literary perspective involving Transcendentalism and intertextuality. Ives's aesthetic builds upon the principles of Transcendentalism. I examine these songs using the principles outlined by the nineteenth-century Transcendentalists, and Ives's interpretations of these beliefs. Another characteristic of Ives's music is quotation. "Intertextuality" describes an interdependence of literary texts through quotation. I also examine these songs using the principles of intertextuality and Ives's uses of intertextual elements. Familiarity with the primary sources Ives quotes and the texts they suggest adds new meaning to his works. Transcendentalism and intertextuality create a greater understanding of Ives's conflicting views of the morality of war.
Trust and Governance in Hybrid Relationships: An Investigation of Logistics Alliances
Transaction cost economics (TCE) theorists traditionally have classified transactions between firms as governed by either market or hierarchy. By assessing characteristics of the transaction - asset specificity, uncertainty, and frequency - firms choose the governance form which minimizes transaction costs, the costs of administering the business deal. During the 1980s, however, TCE has found itself unable to explain the proliferation of strategic alliances. These hybrid relationships seek the benefits of both markets and hierarchies, including quasi-integration, the control of assets without actual ownership. Further, hybrids tend to prefer trust-based relational contracting. TCE's acknowledgment of hybrids, however, raises other questions surrounding the behavioral assumptions which supposedly influence the transaction characteristic governance linkage. Various dissenting researchers have theorized that (1) trust is more dominant in business than opportunism (2) the behavioral assumptions actually function as variables in different contexts, and (3) trust offers an integration mechanism for behavioral variables.
Two-Fold Role of Randomness: A Source of Both Long-Range Correlations and Ordinary Statistical Mechanics
The role of randomness as a generator of long range correlations and ordinary statistical mechanics is investigated in this Dissertation. The difficulties about the derivation of thermodynamics from mechanics are pointed out and the connection between the ordinary fluctuation-dissipation process and possible anomalous properties of statistical systems is highlighted.
Using Assessment as a Method for Surfacing Tacit Knowledge to Influence Business Strategy: a Case Study
In a small, owner-managed, knowledge work firm, assessments were completed on the owners as a method to complete job analysis—surfacing tacit knowledge such as personal characteristics, cognitive style, values and philosophy that contributed to success. Business strategy is often strongly influenced by the tacit knowledge and competencies of the owners, and their unique perspective on the company and marketplace.

Adjustment of Kindergarten Children through Play Sessions Facilitated by Fifth Grade Students Trained in Child-Centered Play Therapy Procedures and Skills
This research study investigated the effectiveness of the application of child-centered play therapy procedures and skills by trained fifth grade students in play sessions with kindergarten children who had adjustment difficulties. Specifically, this research determined if play sessions with trained fifth grade students facilitated change in kindergarten children's self concept, internalizing behavior, and externalizing behavior and their parents' stress level.
An Analysis of Program Options for Gifted Middle School Students
The purpose of this study was to compare three different types of programming options for identified gifted and talented middle school students.
An Analysis of Status: Women in Texas, 1860-1920
This study examined the status of women in Texas from 1860 to 1920. Age, family structure and composition, occupation, educational level, places of birth, wealth, and geographical persistence are used as the measurements of status. For purposes of analysis, women are grouped according to whether they were married, widowed, divorced, or single.
Analyzing the Financial Condition of Higher Education Institutions Using Financial Ratio Analysis.
The problem concerned the financial indicators used to evaluate the financial condition of the six sister higher education institutions under the authority of the Board of Regents of Oklahoma Colleges. The purposes were to determine the financial ratios that best indicate financial condition; to calculate those financial ratios for the six designated Oklahoma higher education institutions; and to evaluate and compare the financial condition of the six institutions. This study attempted to further the use of financial ratio analysis as an objective addition to subjective studies that examine an institution's definition of its mission, objectives, and goals and its own assessment of the degree to which its resources allow it to attain those goals. The data were obtained from the Integrated Postsecondary Education Data System; the financial reports were audited by independent certified public accountants and presented to the Board of Regents of Oklahoma Colleges; and John Minter Associates, Inc., provided the national norms. The set of financial ratios identified provides a means to study a single higher education institution through trend analysis and in comparison to national norms. It also works well with a sample of homogeneous institutions with interinstitutional comparison. The techniques are intended to provide a general profile of an institution’s financial health. Cause-and-effect ratio analysis has been proposed as another technique to aid administrators in determining changes in their financial statements and what may have caused them. The study identified a set of financial ratios that summarize the financial condition of a higher education institution. The ratios helped to analyze the financial solvency and viability of the six Oklahoma higher education institutions and focused on the ability of the institutions to meet current and future financial requirements. The importance of financial statement analysis should not be underestimated. The understandable format of financial ratios allows virtually any stakeholder to acquire a basic comprehension of the most critical financial policies of institutions and their financial condition.
The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan
The United Kingdom's postwar economic recovery and the usefulness of Marshall Plan aid depended heavily on a rapid increase in exports by the country's manufacturing industries. American aid administrators, however, shocked to discover the British industry's inability to respond to the country's urgent need, insisted on aggressive action to improve productivity. In partial response, a joint venture, called the Anglo-American Council on Productivity (AACP), arranged for sixty-six teams involving nearly one thousand people to visit U.S. factories and bring back productivity improvement ideas. Analyses of team recommendations, and a brief review of the country's industrial history, offer compelling insights into the problems of relative industrial decline. This dissertation attempts to assess the reasons for British industry's inability to respond to the country's economic emergency or to maintain its competitive position faced with the challenge of newer industrializing countries.
The Applicability of SERVPERF in Judging Service Quality for Biomedical Information Professionals
The applicability of SERVPERF as a tool for judging the quality of services used by biomedical information professionals was tested using standard statistical procedures. Data was gathered nationally via a combination of electronic and non-electronic forms, from Area Health Education Center (AHEC) information professionals and the results consolidated to provide information for the study. It was determined that SERVPERF was applicable in making judgements about service quality for AHEC information professionals. Their perceptions about service quality tended to have a greater influence than did their level of actual satisfaction on whether or not they planned to use a particular service in the future. There is currently no validated tool available to ascertain the quality of services offered to these valuable members of the rural health care team. This dissertation proposes to provide such a tool, and to serve as a guide or template for other professionals seeking a means to judge service quality in their own disciplines.
Assembly of Pseudomonas putida Aspartate Transcarbamoylase and Possible Roles of the PyrC' Polypeptide in the Folding of the Dodecameric Enzyme
Aspartate transcarbamoylase (ATCase) of Pseudomonas putida consists of two different polypeptides, PyrB and PyrC' (Schurr et al, 1995). The role of the PyrC' and the assembly of PyrB and PyrC' have been studied. The ATCase made in vitro of P.putida PyrB with P.putida PyrC', and of E.coli PyrB with P.putida PyrC ' were generated under two different conditions, denaturation and renaturation, and untreated. It was found that PyrC' plays a role in the enzymatic regulation by ATP, CTP and UTP. In addition to playing a role in substrate binding, the PyrB polypeptide is also involved in effector binding (Kumar et al., manuscript in preparation). The most energetically preferred form of the P.putida WT is a dodecamer with a molecular mass of 480 kDa. The ratio between the PyrB and the PyrC' is 1:1. In studies of nucleotide binding, it was discovered that the P.putida PyrB was phosphorylated by a protein kinase in the cell extract. In the presence of 20 mM EDTA, this phosphorylation was inhibited and the inhibition could be overcome by the addition of divalent cations such as Zn2+ and Mg2+. This result suggested that the phosphorylation reaction required divalent cations. In the CAD complex of eukaryotes, phosphorylations of the CPSase and the linker region between ATCase and DHOase did not occur in the presence of UTP and it was hypothesized (Carrey, 1993) that UTP and phosphorylation(s) regulated the conformational change in the enzyme complex. Therefore, the same idea was approached with P.putida ATCase, where it was found that 1.0 mM UTP inhibited the phosphorylation of PyrB by more than 50%. These results suggested that the regulation of the conformational change of the P.putida ATCase might be similar to that of CAD. Furthermore, peptide mapping for phosphorylation sites was performed on P.putida ATCase WT, WT --11 amino acids and WT --34 amino acids from the N-terminus of the PyrB polypeptide. The results showed that the phosphorylation sites were located on the fragment that contained amino acid number-35 to amino acid number-112 from the N-terminus of the PyrB polypeptide.
Assessing Effects of an Environmental Education Field Science Program Fostering Responsibility at an Urban Middle School
The study investigated the ability of an extracurricular program to influence environmental responsibility of sixth and seventh graders. The Children's Environmental Attitude and Knowledge Survey (CHEAKS) was evaluated for appropriateness in assessing the worth of this particular environmental education strategy emphasizing water quality fieldwork and technology. CHEAKS is designed with psychometric reliability and validity that may be used in comparing disparate programs. Wilcoxon two sample tests were used to analyze data gathered from two student groups; one participated in an "Enviro-Mentals Club"; the other received no treatment. Analysis showed no significant change in environmental attitudes between groups, but did show significance (p <= 0.05) in environmental knowledge growth. Therefore, the investigated program had marginal success in influencing environmental responsibility.
Assessment and Analysis of Per Pupil Expenditures: a Study Testing a Micro-Financial Model in Equity and Student Outcome Determination
The purpose of this study was to examine district level financial data to assess equity across districts, to compare equity benchmarks established in the literature using selected functions from the state's financial database, and to determine the predictive value of those functions to the Texas Assessment of Academic Skills (TAAS) tests of 1997.
Attribution to Deviant and Nondeviant Social Roles.
A questionnaire was used to study causal attribution to social roles as influenced by perceived deviance of the role, instructions to identify with the role, and participant gender. The perceived deviance or nondeviance of the roles was determined by a pilot study. The roles were varied randomly through 12 hypothetical events, and identification or nonidentification instructions randomly assigned. The participants were 194 male and female university students. Participants gave the cause of each event and rated the cause on five dimensions: internality, externality, stability, globality, and controllability. Causal attribution to deviant social roles was found to result in a significantly higher across-scales score and to be more internal, less external, and more global than attribution to nondeviant roles. Participant gender showed an interaction with deviance overall and on the dimensions of stability and globality due to significantly higher ratings by women participants than those by men. Identification instructions did not produce a significant effect.
"But a Mournful Remedy": Divorce in Two Texas Counties, 1841-1880
Little scholarship has been dedicated to nineteenth-century Texas family life and no published scholarship to date has addressed the more specific topic of divorce. This study attempts to fill that gap in the historiography through a quantitative analysis of 373 divorce actions filed in Washington and Harrison Counties. The findings show a high degree of equity between men and women in court decisions granting divorces, and in property division and custody rulings. Texas women enjoyed a relatively high degree of legal and personal autonomy, which can be attributed, in part, to a property-rights heritage from Spanish civil law.
Chaucer and the Rhetorical Limits of Exemplary Literature
Though much has been made of Chaucer's saintly characters, relatively little has been made of Chaucer's approach to hagiography. While strictly speaking Chaucer produced only one true saint's life (the Second Nun's Tale), he was repeatedly intrigued and challenged by exemplary literature. The few studies of Chaucer's use of hagiography have tended to claim either his complete orthodoxy as hagiographer, or his outright parody of the genre. My study mediates the orthodoxy/parody split by viewing Chaucer as a serious, but self-conscious, hagiographer, one who experimented with the possibilities of exemplary narrative and explored the rhetorical tensions intrinsic to the genre, namely the tensions between transcendence and imminence, reverence and identification, and epideictic and deliberative discourse.
Client/Server Systems Performance Evaluation Measures Use and Importance: a Multi-Site Case Study of Traditional Performance Measures Applied to the Client/Server Environment
This study examines the role of traditional computing performance measures when used in a client/server system (C/SS) environment. It also evaluates the effectiveness of traditional computing measures of mainframe systems for use in C/SS. The underlying problem was the lack of knowledge about how performance measures are aligned with key business goals and strategies. This research study has identified and evaluated client/server performance measurements' importance in establishing an effective performance evaluation system. More specifically, this research enables an organization to do the following: (1) compare the relative states of development or importance of performance measures, (2) identify performance measures with the highest priority for future development, (3) contrast the views of different organizations regarding the current or desired states of development or relative importance of these performance measures.
Cognitive Interference in the Perception of Pitch and Loudness in a Five-note Musical Pattern
The purpose of the study was to explore whether musicians experience Garner interference among the auditory dimensions of pitch and loudness. Specifically, the study explored whether the dimensions of intonation and loudness, when presented to musicians in a five-note musical pattern, were perceived as integral or separable in nature.
A Comparative Analysis of Intensive Individual Play Therapy and Intensive Sibling Group Play Therapy with Child Witnesses of Domestic Violence
This study was designed to determine the effectiveness of intensive sibling group play therapy in: (a) improving the self-concept of child witnesses of domestic violence; (b) reducing internalizing behavior problems, such as withdrawal, somatic complaints, anxiety and depression, of child witnesses of domestic violence; (c) reducing externalizing behavior problems, such as aggression and delinquency, of child witnesses of domestic violence; and (d) reducing overall behavior problems of child witnesses of domestic violence. A second objective of this study was to compare the effectiveness of intensive sibling group play therapy and intensive individual play therapy on the above identified dimensions.
A Comparison of Economic Development in Latin America, Middle Eastern Europe and Asia in the 1990s
The 1990s were characterized by severe turbulence in the global economy. Economic and financial crises occurred in Latin America, Middle and Eastern Europe and Asia. This analysis distinguishes between the two socioeconomic criteria "transitional" and "emerging" region. Transitional countries are former centrally planned socialist economies and emerging countries former agricultural-oriented classical developing economies with mostly a history of military or some other kind of autocratic dictatorship. The resources for the analysis are data sets regarding investment, exchange rate behavior, government finance, international liabilities of monetary authorities and inflation. The study reveals macroeconomic patterns associated with economic development in each socioeconomic region. It is shown that similar patterns are responsible for successful and non-successful performance in each region. A comparison of different regions shows many parallels between emerging economies, but only little similarity between transitional economies.
A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, TX Based on Chlorophyll A
Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.
A Computer-Based Process Control System for a Target Station in a LINAC Facility
An event-driven, sequential, process control system was designed for International Isotopes, Inc., to automate and remotely control a target station at the company's linear accelerator facility. The designed system consisted of two major sections: a software program (virtual instrument), which was developed by LabVIEW, and a hardware interface (FieldPoint Modular Distributed I/O System by National Instrument), which had to be a pre-developed system that did not require customization. The designed virtual instrument was tested on a simulation model that mimed the target station. The result was a valid design.
Construction of a Physical Map of Moraxella (Branhamella) catarrhalis Strain ATCC25238
In order to gain a better understanding of this microorganismand its role in human pathogenesis, a physical map of Moraxella catarrhalis type strain ATCC25238 was constructed using pulsed field gel electrophoresis (PFGE) in combination with Southern hybridization techniques. Restriction endonucleases Not I, Rsr II, and Sma I were used to digest the chromosomal DNA. An overlapping circular map was generated by cross-hybridization of isolated radiolabeled fragments of Moraxella catarrhalis genomic DNA to dried PFGE gels. The number and location of the 16S and 23S ribosomal RNA genes were determined by digestion with l-Ceul enzyme and by Southern hybridization. Virulence-associated genes, the gene for β-lactamase, and housekeeping genes were also placed onto the physical map.
Continuity Expectations in Vertical Marketing Systems: a Dyadic Perspective of Domestic and International Franchising
An emerging paradigm shift in the marketing discipline has prompted renewed research interest in the nature and scope of exchange. A common theme in the research to date is a departure from the traditional transactional orientation to a relational perspective of exchange. The relational emphasis is particularly germane to contractual Vertical Marketing Systems (VMS) where the emphasis is on long-term, mutually beneficial interaction between various channel members. The franchisor-franchisee relationship, a type of contractual VMS, is governed by norms that impact system efficiency and effectiveness. Despite the unprecedented growth of international franchising systems in the marketplace, a paucity of empirical attention has focused on cross-national franchisor-franchisee relationships. With many U.S.-based business format franchisors penetrating foreign markets, the primary purpose of the dissertation is to provide insights into tools which franchisors, and franchisees can use during the evolution of the exchange relationship. To identify differences across geographic boundaries, the dissertation simultaneously studies domestic and cross-border franchisor-franchisee relationships.
Cultural Influences on the ABC Implementation under Thailand's Environment
This study examines the influences of culture on the implementation of a U.S.-based Activity-Based Costing (ABC) in three Thai organizations.
Design of a Monitoring System for a Plasma Cleaning Machine
Plasma cleaning is the most effective dry process to remove surface contaminates from a SAW (Surface Acoustical Wave) device. Consistent gas pressures, flows, and good electrical connections between the chamber shelves are necessary for the process to function predictably. In addition, operation of the monitoring system must be transparent to the plasma cleaning unit. This thesis describes a simple solution to the complex problem of monitoring a plasma cleaning system. The monitoring system uses the LabVIEW® G programming language and hardware, both products of National Instruments, Inc.®, to monitor critical parameters necessary to achieve a consistent process when cleaning these devices.
Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems
The current study discussed the development and validation of the Checklist for Differential Diagnosis of Attentional Problems (CDDAP), a tool for use with adults seeking diagnosis and treatment of an Attention Deficit Hyperactivity Disorder. Normative data are provided on three subject groups (ADHD adults, controls, and adults with other psychiatric disorders). Convergent validity was established with the SCL-90, and criterion validity established through comparing scaled scores with final diagnoses. Overall, this measure was accurate at differentiating adults with ADHD from controls and adults with other psychiatric disorders. Results indicated that the CDDAP was also able to identify other psychiatric disorders with 71 to 92% accuracy, depending on the disorder.
Development and Validity of the Teachers' Attitude, Comfort and Training Scale (TACTS) on Sexuality Education
The purpose of the study was to design and validate an instrument designed to investigate teachers' attitudes in regard to adolescent sexuality education. Test development adhered to the guidelines of Aligna and Crocker. Cronbach alpha was performed on the entire instrument and determined the reliability to be .8003, thus the instrument was consistent in measuring the domain areas. A panel of experts assessed content validity of items. A principal component factor analysis and a Pearson's product moment correlation were used for construct validity. Teacher concerns about curriculum implementation, teacher comfort with the subject matter, course-specific teacher attitudes, teacher interest about curriculum content, and teacher attitudes toward sexuality were found to be the constructs of the TACTS.
A Different Drummer: A Chamber Opera
Access: Use of this item is restricted to the UNT Community.
A Different Drummer is a chamber opera adaptation of Donald Davis's story "A Different Drummer" from his collection Listening for the Crack of Dawn, published by August House. The opera lasts about seventy minutes, and calls for a cast of three and an orchestra of sixteen players. It contains a prologue, epilogue and four scenes in a single act. The score is prefaced by a paper describing the musical strategies employed in setting the story as an opera. Three chapters describe the adaptation from short story to opera, the essential musical elements, and details of the application of the musical elements in each scene of the opera. The libretto is presented in the fourth chapter.
The Effect of Presence of Support Systems and Level of Agreement on the Performance of Work Groups
In the study of team-based organizations most of the research has focus on the internal make-up and structure of teams. Recently there has been more interest in the effects that environment has on teams. With this new focus Support Systems in organizations have become an area of interest. Examining the perceptions of workers with respect to support systems of organizations could give insight into performance. This study specifically examines the interaction between a team's shared perception of the support in their environment and the level of support in their environment. The interaction between the two does seem to have a strong relationship with perceived performance. How do the two concepts interact, and what does this mean for organizational designers? Both questions are discussed.
The Effects of a Brain-based Learning Strategy, Mind Mapping, on Achievement of Adults in a Training Environment with Considerations to Learning Styles and Brain Hemisphericity
This study examined the effectiveness of Mind Mapping (a diagram of the structure of ideas in an associative manner, using graphics, color and key words) as a note-taking device in a training course in a large, high-tech corporation, as compared to traditional note-taking. The population for this study consisted of personnel employed by a major high-tech firm, that had voluntarily registered for a Mind Mapping training class. The effect of Mind Mapping was measured by the pre-test and post-test of the control and experimental groups.
Effects of Instructional Methods on Student Performance in Postsecondary Developmental Mathematics
This study examined success rates and end-of-semester grades for three instructional methods used in developmental algebra and college algebra. The methods investigated were traditional lecture, laboratory, and computer mediated learning. The population included the 10,095 students who had enrolled in developmental algebra and college algebra at Richland College in Dallas, Texas, for five semesters. Success was defined as earning a grade of A, B, C, or D in a course.
The Effects of Organic Surface Amendments on Soil Nutrients and Initial Tree Establishment
This study examined the effects of replicating woodland soil surface horizonation on the nutrient status of underlying soils and the initial establishment and growth of trees. A total of 283 container grown trees were planted in a bufferzone around a future landfill site. Control amendments consisted of an 8 cm layer (0.5 m3) of wood chips applied in a circular area of 4.6 m2 around the trees' planting pit. For the treatment, a 2.5 cm layer of composted biosolids (0.15 m3 or 80 Mg/ha) was applied in a circular area of 4.6 m2 around the trees' planting pit followed by an 8 cm layer (0.5 m3) of wood chips. The results indicate that the replication of woodland soil surface attributes using composted biosolids can significantly improve the nutrient status of underlying soil. Some significant effects were seen under control conditions, too. However, the effects on tree establishment and growth parameters were, for the most part, not statistically significant.
The Effects of Task-Based Documentation Versus Online Help Menu Documentation on the Acceptance of Information Technology
Access: Use of this item is restricted to the UNT Community.
The objectives of this study were (1) to identify and describe task-based documentation; (2) to identify and describe any purported changes in users attitudes when IT migration was preceded by task-based documentation; (3) to suggest implications of task-based documentation on users attitude toward IT acceptance. Questionnaires were given to 150 university students. Of these, all 150 students participated in this study. The study determined the following: (1) if favorable pre-implementation attitudes toward a new e-mail system increase, as a result of training, if users expect it to be easy to learn and use; (2) if user acceptance of an e-mail program increase as expected perceived usefulness increase as delineated by task-based documentation; (3) if task-based documentation is more effective than standard help menus while learning a new application program; and (4) if training that requires active student participation increase the acceptance of a new e-mail system. The following conclusions were reached: (1) Positive pre-implementation attitudes toward a new e-mail system are not affected by training even if the users expect it to be easy to learn and use. (2) User acceptance of an e-mail program does not increase as perceived usefulness increase when aided by task-based documentation. (3) Task-based documentation is not more effective than standard help menus when learning a new application program. (4) Training that requires active student participation does not increase the acceptance of a new e-mail system.
The Electronic Ranch: the Information Environment of Cattle Breeders
The present study was a longitudinal analysis of the information needs of Red Angus cattle breeders and their use of networked information services. It was based on two surveys. The first, conducted in 1995--96, polled all 1067 ranches of the Red Angus Association of America. Responses from 192 Red Angus breeders were used to determine the value of different information types and to evaluate perceptions of the greatest barriers to the adoption of network information services. The second survey, mailed to 41 Red Angus breeders in 1998, focused on early adopters and likely users of network services. Responses from 15 breeders were used to evaluate perceptions of the greatest barriers to the effective use of Web-based information services.
Ethnically mixed individuals: Cultural homelessness or multicultural integration?
Studies addressing racial/ethnic identity development have often overlooked the developmental cultural context. The impact of growing up with contradictory cultures has not been well explored. Immersion in multiple cultures may produce mixed patterns of strengths deficits. This study reviews the literature's currently inconsistent usage of the terms race, ethnicity, and culture; introduces the concept and theoretical framework of Cultural Homelessness; relates CH to multicultural integration; and develops two study-specific measures (included) to examine the construct validity of CH. The sample’s (N = 448, 67% women) racial, ethnic, and cultural mixture was coded back three generations using complex coding criteria. Empirical findings supported the CH-specific pattern of cognitive and social strengths with emotional difficulties: social adaptability and cross-cultural competence but also low self-esteem and shame regarding diff
Everything and Nothing at the Same Time
This paradoxically titled collection of poems explores what the blues and blindness has come to mean to the author.
Evolution of Vacancy Supersaturations in MeV Si Implanted Silicon
High-energy Si implantation into silicon creates a net defect distribution that is characterized by an excess of interstitials near the projected range and a simultaneous excess of vacancies closer to the surface. This defect distribution is due to the spatial separation between the distributions of interstitials and vacancies created by the forward momentum transferred from the implanted ion to the lattice atom. This dissertation investigates the evolution of the near-surface vacancy excess in MeV Si-implanted silicon both during implantation and post-implant annealing. Although previous investigations have identified a vacancy excess in MeV-implanted silicon, the investigations presented in this dissertation are unique in that they are designed to correlate the free-vacancy supersaturation with the vacancies in clusters. Free-vacancy (and interstitial) supersaturations were measured with Sb (B) dopant diffusion markers. Vacancies in clusters were profiled by Au labeling; a new technique based on the observation that Au atoms trap in the presence of open-volume defects. The experiments described in this dissertation are also unique in that they were designed to isolate the deep interstitial excess from interacting with the much shallower vacancy excess during post-implant thermal processing.
Faculty Identification: Effects on Culture in a Metropolitan Research University
This utilized identification theory to determine if faculty identify with the university and recognize its mission. The study also explored how faculty differentiate between a traditional university and a metropolitan research university. Finally, the study explored whether the faculty consider the University of North Texas to be a Metropolitan Research University. UNT full-time faculty members (N=224) completed questionnaires to indicate their identification with the university and their recognition of the university mission. Analysis showed that faculty have not come to a consensus on the definition of a MRU and that they do not identify with UNT.
From Skeletons to Orchards
This thesis is a creative work that is segmented into three main phases in order to display the developing poetic growth and control in the work of Paul Andrew Thies. The first phase is titled "Skeletons and Rhinoceri." It was a phase where I focused on more classical forms of poetry, namely accentual and syllabical sonnets. This phase was greatly influenced by both Charles Baudelaire and William Butler Yeats. The second phase, titled "Clandestinies," was one in which I tried to develop a more dense form. Lord Byron and Pablo Neruda were the two main influences on my work at this time, largely in terms of imaginative exoticism and figurative energy. The third section of this thesis, titled "Graffiti in the Orchard," is an exploration of my current work as a poet. In this phase, Rainer Maria Rilke was the primary influence as I began to develop a more fluid and expressive style.
Image and Identity at El Santuario de Chimayo in Chimayo, New Mexico
El Santuario de Chimayo is a small community shrine that combines both native Tewa Indian and Christian traditions. This study focuses on the interaction between traditions through analysis of the shrine's two major artworks: a crucifix devoted to El Senor de Esquipulas (Christ of Esquipulas) and a statue of the Santo Nino (Holy Child). The shrine and its two primary artworks are expressions of the dynamic interaction between native and European cultures in New Mexico at the beginning of the nineteenth century. They frame the discussion of native and Christian cultural exchange about the relationships between religious images, how they function, and how they are interpreted.
Interspecific Competition between Hygrophila polysperma and Ludwigia repens, Two Species of Importance in the Comal River, Texas
Hygrophila polysperma is a plant native to Asia that has been introduced into the Comal River, TX and is thriving while Ludwigia repens, a species native to the river appears to be declining. Both plants have similar morphologies and occupy similar habitats in the river. Two plant competition experiments were conducted to examine the competitive interactions between the two species. First, an experimental design was developed in which established Ludwigia plants were 'invaded' by sprigs of Hygrophila to determine if established Ludwigia populations would be negatively impacted by invasion. The second experiment focused on establishment and growth of sprigs of each species under three competition scenarios. Results show that the continued growth of well-established Ludwigia plants was significantly depressed by the invasion of Hygrophila in comparison with those that had not been invaded. Furthermore, the growth of Hygrophila sprigs was uninhibited by the presence of Ludwigia, but the presence of Hygrophila negatively impacted the growth of Ludwigia sprigs. There was no difference in the growth of Hygrophila sprigs whether planted alone, with Ludwigia sprigs or even if planted into stands of established Ludwigia.
An Investigation of the Efficacy of Play Therapy with Young Children
This study was designed to determine the effectiveness of play therapy as a method of intervention for children with a variety of emotional and behavioral problems. Specifically, the study was aimed at determining the effectiveness of play therapy in: (a) improving self-concepts of children with adjustment difficulties; (b) reducing internalizing behavior problems, such as withdrawal, somatic complaints, anxiety, and depression; (c) reducing externalizing behavioral problems such as aggression and delinquent behaviors; (d) reducing overall behavior problems, social problems, thought problems, and attention problems of children with adjustment difficulties; and (e) reducing parenting stress of parents of children who were experiencing adjustment difficulties.The experimental group consisted of 15 children who were experiencing a variety of adjustment difficulties and received play therapy once per week for 7 to 10 weeks. The control group consisted of 14 children who were experiencing a variety of adjustment difficulties and who were on a waiting list to receive intervention, and therefore, did not receive any treatment during the time of data collection. Experimental and control group children were administered the Joseph Pre-School and Primary Self-Concept Screening Test and parents of all participants completed the Child Behavior Checklist and the Parenting Stress Index at pretest and posttest data collection times. A gain scores analysis revealed that children in the experimental group demonstrated a significant improvement on internalizing behavior problems. Also, a reduction in externalizing behavior problems and parenting stress was observed. No improvement in self-concept was demonstrated. This study provides evidence that play therapy is a viable intervention for treating a variety of emotional and behavioral difficulties in young children, particularly children who are experiencing internalizing behavior problems.
