Organizational Support Systems for Team-Based Organizations: Employee Collaboration through Organizational Structures: The purpose of this study was to examine relationships between organizational support and Effectiveness, Empowerment, and team characteristics. Support was operationalized by nine systems: Executive Management, Direct Supervision, Group Design, Performance Definition, Performance Review, Training, Rewards, Information, and Integration. Support was rated in two ways: how important is support for performing work (Importance scales), and how does support describe work environments (Presence scales).
Determinants and Outcomes of Salespeople's Coping Style: Some salespeople cope with the chronic stress that accompanies sales jobs better than others. That is, while all salespeople possess some ability for coping with job stress, some coping mechanisms work better than others. Thus, it is critically important to identify the coping mechanismwhich are associated with the most positive organizational outcomes (i.e., higher performance, increased retention). Research on the coping mechanisms of salespeople is in its exploratory stage. Increased knowledge concerning how salespeople cope with chronic job stress would help researchers and managers to clarify why certain job outcomes occur instead of others (i.e., performance, retention, and burnout). This study proposes and tests a set of relationships pertaining to the dimensionality and the outcomes of salespeople's coping styles. The model identifies the antecedents of coping style and proposes three types of coping style salespeople employ to reduce job stress- emotion focused coping (EFC), problemfocused coping (PFC) and action oriented coping (AOC). It also elucidates the outcomes associated with EFC and PFC styles. The empiricalfindingssuggest that among salespeople, those who use PFC possess a more pronounced internal locus of control, perceive higher social support, and project higher continuance commitment, and higher self efficacy than those who use EFC. The findings also suggest that salespeople who use PFC tend to be more satisfied and express greater well being than those who use EFC. Additionally, salespeople who use EFC tend to exhibit greater propensity to burnout and greater tendency to withdraw than those who use PFC. The model holds considerable promise froma managerial standpoint. Because the model partially predicts whether the outcome of a particular coping style will be positive or negative, managers can train their salespeople to cope with job stress more effectively. Additionally, it may be significantly helpful to those who recruit salespeople. Sales recruiters ought to be able to …
The Effects of Child-Centered Play Therapy Training on Trainees: This study was designed to determine the effects of child-centered play therapy as a play therapy training model for beginning play therapy students. The purpose of this study was to determine the effects of child-centered play therapy training on play therapy trainees in (a) improving positive attitudes and beliefs toward children; (b) improving knowledge of child-centered play therapy; (c) improving confidence in applying child-centered play therapy skills; (d) reducing dominance tendencies in trainees' personality as measured by the California Psychological Inventory; and (e) increasing tolerance levels in trainees' personality as measured by the CPI. The experimental group, consisting of 37 counseling graduate students with a specialty in child counseling, received 45 clock hours of introduction to play therapy graduate course training at the University of North Texas, Denton. The control group, consisting of 29 counseling graduate students with a specialty in child counseling, received other counseling graduate courses training but no play therapy training at the time of their participation in this study at the University of North Texas. Both experimental and control group students completed the pretest and the posttest on the Play Therapy Attitude Knowledge Skills Survey and the California Psychological Inventory at the beginning and the end of the semester terms of Fall 1995, Spring 1996, and Summer 1996. Analyses of covariance revealed that students in the experimental group demonstrated (a) a significant improvement in their positive attitudes and beliefs toward children; (b) a significant improvement in their child-centered play therapy knowledge; (c) a significant improvement in their confidence in applying child-centered play therapy skills; and (d) a significant reduction in their dominance tendency. An insignificant result was found in their tolerance level. This study suggests that child-centered play therapy training is a viable training model for prospective and beginning play therapists.
The Impact of Contextual Variables on Internal Auditors' Propensity to Communicate Upwardly: The author examined whether contextual variables impact internal auditors' self-assessed likelihood of whistleblowing. The author synthesized a theoretical framework and developed research hypotheses that predict relationships between the self-assessed likelihood of whistleblowing and (1) magnitude of the consequences (2) channels of communication and (3) type of wrongdoing. To test these hypotheses, the author provided internal auditors (n=123) with a scenario and asked them to self-assess the likelihood of reporting evidence of a malfacation to their internal audit director even though their audit manager told them to ignore the wrongdoing.
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.
Adult Discouragement: Traditonal College Students: This study resulted in the development of the Discouragement Scale for Adults (DSA), an assessment instrument for the Adlerian construct of discouragement in adults more than 18 years of age. The DSA is a 60-item instrument that contains five sub-scales corresponding to five life tasks identified in Adlerian literature as work, love, society, self, and spirituality. Age, gender, and ethnicity norms were established for the DSA using a diverse sample (N=586). Additional normative data was developed with a presumed discouraged sample (N=47), and a special sample of traditional college students aged 18-27 years (N=531). Findings on the norm sample indicated that females are less discouraged than males on the Total DSA and on society and spirituality sub-scales. The 18-34 year old group was more discouraged than other age groups on the Total DSA and on work, society, and spirituality sub-scales. Presumed discouraged sample findings indicated that females were less discouraged than males on the society sub-scale. College student findings indicated that females were less discouraged than males on the Total DSA and sub-scales of love, society, spirituality, and work. A significant difference was found among ethnic groups in self sub-scales. Students with no absences per week were less discouraged than students with two absences per week. Students with lower grade point averages (GPA) were more discouraged on the Total DSA and work sub-scales. DSA internal consistency coefficients were .9392, .9496, and .9327 for norm, presumed discouraged, and college student samples respectively. Correlations between DSA and two social interest surveys reflect an inverse relationship between discouragement and social interest. Results indicate that the DSA is a useful assessment instrument for research and counseling purposes with college students. Further research should include greater geographical and ethnic diversity as well as validation among diverse college samples and non-traditional students. Additionally, a standard range …
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 Risks and Effects of Outsourcing on the Information Systems Function and the Firm: IS outsourcing, especially large-scale IS outsourcing, is a comparatively recent and rapidly growing IS phenomenon, but it is also an inherently risky activity. In an IS outsourcing arrangement, the outsourcing vendor accepts responsibility for IS resources and functions formerly controlled directly by the firm. This research examines IS outsourcing from two perspectives. (1) From an IS perspective, it examines the risk perceptions of IS managers of fourteen Fortune-500 firms who had recently conducted an outsourcing evaluation. (2) From a financial perspective, it examines the theoretical relationship of IS outsourcing with financial performance, and investigates the empirical effects of IS outsourcing on the firm's market value and market risk. This research views IS outsourcing as an independent variable whose effects on the firm may be measured as changes in security returns, changes in asset risk, changes in capital structure, and long-term changes in profitability. To accomplish this, it characterizes IS outsourcing as a sale-and-leaseback transaction.
Population Policy Implementation and Evaluation in Less Industrialized Countries: This study emphasizes the impact of family planning program components on contraceptive prevalence in less industrialized countries. Building on Lapham and Mauldin's "Program Effort and Fertility Decline" framework and policy evaluation's theory, the author developed two models to examine the impact of family planning programs on contraceptive prevalence and fertility under the constraints of socioeconomic development and demand for family planning. The study employed path analysis and multiple regression on data from the 1982 program effort study in 94 less developed countries (LDCs) by Lapham and Mauldin and 98 LDCs of the 1989 program effort study by Mauldin and Ross. The results of data analyses for all data sets are consistent for the most part. Major findings are as follows: (1) A combination of program effort and socioeconomic development best explains the variation of contraceptive prevalence. (2) Among socioeconomic variables, female literacy exerts the strongest direct and indirect influences to increase contraceptive prevalence and indirect influence to decrease total fertility rate. (3) Christianity performs a significant role in reducing contraceptive prevalence. (4) Among program effort components, availability and accessibility for fertility-control supplies and services have the most influence on contraceptive prevalence. (5) When controlling for demand for family planning, female literacy and Christianity have expected and significant relationships with contraceptive prevalence. Availability and accessibility to fertility-control supplies and services exerts a positive and statistically significant impact on contraceptive prevalence. Demand for family planning has a positive and statistically significant effect on program variables, availability, and contraceptive prevalence. (6) There is a strong inverse relationship between contraceptive use and fertility. Demand for family planning, program effort, and socioeconomic development influence fertility through contraceptive prevalence. The findings of this study suggest that governments in LDCs should give priorities to increasing female education and availability of contraception to effectively reduce fertility.
A Comparative Analysis of Curricular Programs in Private, Public Choice, and Public Attendance-Zone Schools in San Antonio, Texas: The purpose of this study was to examine curricular programs in private, public choice, and public attendance-zone schools to determine whether differences exist among curricular programs in the three types of schools. The findings from the student survey data indicated that private school students reported their curriculum to be more challenging than public school students, but no other significant differences were noted. Findings from the teacher survey showed more positive results for private schools in indicators of a challenging curriculum, expectations of students, school climate, and external support than public schools. This study showed that of the types of schools examined, Catholic schools exhibited the most consistent and well written curriculum that reflected the four research questions. Future research needs to be done to establish whether these indicators of a challenging curriculum result in higher student achievement.
The Relationships of Cross-Cultural Differences to the Values of Information Systems Professionals within the Context of Systems Development: Several studies have suggested that the effect of cultural differences among Information Systems (IS) professionals from different nations on the development and implementation of IS could be important. However, IS research has generally not considered culture when investigating the process of systems development. This study examined the relationship between the cultural backgrounds of IS designers and their process-related values with a field survey in Singapore, Taiwan, the United Kingdom and the United States. Hofstede's (1980) value survey module (i.e., Power Distance (PDI), Uncertainty Avoidance (UAI), InDiVidualism (IDV) and MASculininity/femininity) and Kumar's (1984) process-related values (i.e., technical, economic, and socio-political) were utilized in the data collection. The hypotheses tested were: whether the IS professionals differed on (H.,) their cultural dimensions based on country of origin, (Hg) their process-related values based on country of origin, and (H3) whether a relationship between their cultural dimensions and their process-related values existed. The countries were significantly different on their PDI, UAI and MAS, but not on their IDV. They significantly differed on their technical and sociopolitical values but not on their economic values. IDV and MAS significantly correlated with the process-related values in Singapore, Taiwan and the United States. In the United Kingdom, UAI significantly correlated with socio-political values; and MAS significantly correlated with technical and socio-political values. In Taiwan, UAI significantly correlated with technical and economic values. PDI did not illustrate any significant correlation with the IS process-related values in all four countries. In Singapore and the United States, UAI did not significantly correlate with any of these values. The results provide evidence that IS professionals differ on most of their cultural dimensions and IS process-related values. While IDV and MAS could be useful for examining the relationship between culture and systems development, research involving PDI and UAI might be of questionable benefit.
Visions of Light In the Poetry of William Blake and Emily Dickinson: In this study the author compares the broad outlines of Blake's and Dickinson's thought, pointing out evidence of decisive Biblical influence not only on the content of their thought but on their attitude toward language as well. the author argues that both poets assumed the philosophical position of Job as they interpreted the Bible independently and as they explored many dimensions of experience in the fallen world. The author represents their thought not as a fixed system but as a faith-based pattern of Christian/Platonic questing for truth.
Impacts of the Pyrethroid Insecticide Cyfluthrin on Aquatic Invertibrate Populations in Outdoor Experimental Tanks: The chemical fate and biological impacts of cyfluthrin in aquatic ecosystems were investigated using microcosms (1.9 m^3 concrete tanks) during 1989. Results were compared to a concurrent pesticide registration study using mesocosms (634.7 m^3 earthen ponds). Ten spray drift and five soil runoff simulations were conducted. Pesticide loadings were scaled by system volume, with the same experimental design in ponds and microcosms. Aqueous cyfluthrin concentrations and sediment residue values were generally higher in microcosms, while aqueous half-life was shorter in the smaller systems.
Three Essays in Corporate Governance: Corporate governance issues have become increasingly important to financial managers and shareholders. Firms that are plagued by poor performance, incompetent managers, or excess agency costs have become the subject of a dramatic increase in shareholder activism. Dissident shareholders, who are unable to launch costly takeover bids or proxy contests, have initiated a process of governance reform through the use of shareholder sponsored proposals. Shareholder proposals are a direct attempt to reverse operating or voting policies, such as a proposal to repeal a classified board. Managers announce shareholder proposals in a proxy statement and typically include a vote recommendation against the proposal. In the first essay, I find an unfavorable stock price reaction to the announcement of a shareholder proposal. In some cases, however, management supports the proposal and negotiates an agreement with the proposing shareholder. Stock prices react favorably to a settlement announcement. If managers are willing to negotiate with shareholders, they are perceived to be acting in the best interest of shareholders. If managers are unwilling, shareholders believe a severe agency problem exists. In the second essay, the effect that ownership structure has on voting outcomes of shareholder proposals is examined. I find a direct relationship between the percentage of votes cast in favor of the proposal and levels of institutional ownership. There is an inverse relationship between the percentage of votes and managerial ownership and firm size. Large firms with powerful owner-managers present the greatest obstacle to the success of shareholder proposals. The repeal of shareholder rights plans is one of the most frequently used shareholder proposals. By adopting the rights plan, managers increase the probability of defeating a takeover, but increase their power in negotiating with a potential acquiring firm. In the third essay, I find that firms who combine a rights plan with high debt levels …
Quantum-Confined CdS Nanoparticles on DNA Templates: As electronic devices became smaller, interest in quantum-confined semiconductor nanostructures increased. Self-assembled mesoscale semiconductor structures of II-VI nanocrystals are an especially exciting subject because of their controllable band gap and unique photophysical properties. Several preparative methods to synthesize and control the sizes of the individual nanocrystallites and the electronic and optical properties have been intensively studied. Fabrication of patterned nanostructures composed of quantum-confined nanoparticles is the next step toward practical applications. We have developed an innovative method to fabricate diverse nanostructures which relies on the size and a shape of a chosen deoxyribonucleic acid (DNA) template.
Citation Accuracy in the Journal Literature of Four Disciplines : Chemistry, Psychology, Library Science, and English and American Literature: The primary purpose of this study was to determine if there is a relationship between the bibliographic citation practices of the members of a discipline and the emphasis placed on citation accuracy and purposes in the graduate instruction of the discipline.
The Role of Contract Training by Academic Institutions in Corporate Education and Training Programs: This study explored the role of contract training provided by North Texas higher education institutions in the education and training programs administered by area businesses employing more than 100 people. A survey instrument was mailed to corporate trainers that were members of the Dallas Chapter of the American Society of Training and Development in businesses employing more than 100 people. A total list of 292 trainers generated 71 usable responses. The purposes of this study were to: (a) determine the extent to which corporations use academic institutions for contract training, (b) determine the academic institutions in North Texas that training managers in the Dallas area believe are suitable contract training partners, (c) identify what subject areas are perceived as top educational priorities by training managers and are perceived to be suitable for contract training by academic institutions, (d) determine educational and training subjects for which corporations would be willing or prefer to utilize contract training by academic institutions, and (e) identify the subjects in which corporations currently use contract training by academic institutions.
Analysis of Job Prospects and the Relevance of Printing Education to the Printing Industry: A Case of Nigeria: The overall purpose of this study was to determine the job prospects and relevance of printing education to the printing industry. The study was conducted in four Nigerian cities—Lagos, Kaduna, Kano and Benin City.
Beyond the Merchants of Death: the Senate Munitions Inquiry of the 1930s and its Role in Twentieth-Century American History: The Senate Munitions Committee of 1934-1936, chaired by Gerald Nye of North Dakota, provided the first critical examination of America's modern military establishment. The committee approached its task guided by the optimism of the progressive Social Gospel and the idealism of earlier times, but in the middle of the munitions inquiry the nation turned to new values represented in Reinhold Niebuhr's realism and Franklin D. Roosevelt's Second New Deal. By 1936, the committee found its views out of place in a nation pursuing a new course and in a world threatening to break out in war. Realist historians writing in the cold war period (1945-1990) closely linked the munitions inquiry to isolationism and created a one-dimensional history in which the committee chased evil "merchants of death." The only book-length study of the munitions investigation, John Wiltz's In Search of Peace, published in 1963, provided a realist interpretation. The munitions inquiry went beyond the merchants of death in its analysis of the post-World War I American military establishment. A better understanding emerges when the investigation is considered not only within an isolationist framework, but also as part of the intellectual, cultural, and political history of the interwar years. In particular, Franklin Roosevelt's political use of the investigation becomes apparent. Sources used include the committee's hearings, exhibits, and reports, the Gerald Nye Papers, the Franklin Roosevelt Papers, the Cordell Hull Papers, the R. Walton Moore Papers, the Henry Stimson Papers, the Homer Cummings Diaries, and the State Department's decimal files.
Women Who Survived Childhood Sexual Abuse: Do Their Coping Strategies Vary by Personality Type as Measured by the Myers-Briggs Type Indicator?: Through a phenomenological qualitative approach, this study examined possible differences of introverted versus extraverted adult female survivors of childhood sexual abuse with regard to the coping mechanisms they chose. Preference modalities of introversion and extraversion were measured by the Myers-Briggs Type Indicator and data was collected through a semi-structured interview designed by the researcher. The interview contained questions about the 21 subjects' perceptions of their abuse and the ways in which they coped. Specific coping mechanisms included but were not limited to eating disorders, alcohol and/or drug abuse, high risk behavior, depression, anxiety, and somatic complaints. Results indicated that for both groups, the degree to which each of the individual coping mechanisms was used congregated at the level of "a driven pattern of behavior lasting for at least 7 days" or "on-going use resulting in severe problems". Extraverts showed higher percentages of severe use of the six coping mechanisms than did introverts. Depression was the most frequently used coping mechanism of both the introverts and the extraverts. Introverts showed higher percentages of stopping the use of eating disorders, alcohol/drug abuse, high risk behavior, and depression. Extraverts had higher percentages of discontinued use of anxiety and somatic problems. Introverts reported more somatic complaints, while extraverts reported more severe somatic problems. The most often reported somatic complaints of both groups were arthritis, migraines, sleep difficulty, nightmares, and gastrointestinal problems. The majority of each group used most of the coping mechanisms at some time, suggesting a need for therapeutic intervention that considers the possibility of difficulties stemming from combined use of many of these coping mechanisms in addition to focusing on the trauma of the sexual abuse itself.
The Effects of Stock Delistings on Firm Value, Risk, Market Liquidity and Market Integration: With Evidence on Wealth Effects from the Stock Exchanges of Malaysia and Singapore, Using GARCH: This study examines the effects of delisting on firm value, risk and market liquidity. In a world where markets are becoming increasingly integrated, delistings may prove counter productive. We use the unique event, free from company specifics, that occurred on January 2, 1990 in the stock exchanges of Singapore and Malaysia to test for the above effects. On that day, dual listed companies were required to delist from the foreign stock exchange. We also use this event to test if the Singapore and Malaysia markets are globally integrated. Since financial data is found to show persistence in volatility, we model the return generating process in a generalized autoregressive conditionally heteroskedastic (GARCH) framework that takes into consideration changing volatility. For comparison purposes, OLS and Time-Deformation models are included. The study found delistings to decrease firm value, the size of which is related to how actively the stocks were previously traded on the foreign stock exchange. Risk levels increased following delistings. Nevertheless, thinly traded stocks showed significant changes in neither firm value nor riskiness. Further evidence of new listings to increase firm value was noted. Consistent with the political motive hypothesis, delisted stocks showed an increase in post-event volume, but however, lost relative liquidity compared with other stocks. While all portfolios considered show evidence for existence of conditional heteroskedasticity, comparison with standard OLS event-study results yields similar conclusions, although the return generating models with GARCH errors result in lower abnormal return variances. As for the time-deformation model, trading volume was found to be a good proxy for rate of information flow only for smaller capitalized stocks. Correlation and regression analyses showed that the Singapore and Malaysia markets are integrated to some degree with the international markets, such that a major delistings event between both markets did not change the pricing of risk …
An Analysis of Factors Associated with Voluntary Disclosure of Management's Responsibilities for Internal Control: The purpose of this study was to identify company characteristics associated with the presence of disclosures regarding internal control in the annual report. Gibbins, Richardson and Waterhouse [1990] have developed a framework from which to examine financial disclosure,. These authors define two dimensions of a company's disclosure position; opportunism and ritualism. I examined the association between variables representing the dimensions identified by these authors and a company's decision regarding disclosure of a management report on internal control. I compared specific characteristics of companies disclosing this information to those of companies not disclosing. The dependent variable represented the presence or absence of disclosure. I used logit analysis to test the significance of the chosen characteristics relative to the decision to include or exclude a management report on internal control in the annual report. My results were consistent with the existence of ritualism with respect to this issue. Reporting on internal controls was associated with membership in the Financial Executives Institute, auditor choice, certain industry designations and prior inclusion of such a report. FEI membership was closely related to initial reporting decisions as well'. I found evidence of opportunism as well. The likelihood of reporting on internal controls was related to company size (and presumably control strength), and growth rates. I also found an association between reporting and the issuance of publicly traded securities in the succeeding year and more moderate levels of debt relative to an industry average. In addition, I found that initial reporting decisions were associated with external events relating to potential legislation of the reporting issue. This research provides insight into the corporate response to reporting on internal controls.
A Collapsing Result Using the Axiom of Determinancy and the Theory of Possible Cofinalities: Assuming the axiom of determinacy, we give a new proof of the strong partition relation on ω1. Further, we present a streamlined proof that J<λ+(a) (the ideal of sets which force cof Π α < λ) is generated from J<λ+(a) by adding a singleton. Combining these results with a polarized partition relation on ω1
The Process of Sharing Team Leadership : A Study of Key Leadership Behaviors and Who Exhibits Them: Using a manufacturing setting that is organized into self-managed teams, the current study identified and measured key leadership behaviors within the teams. Questions that were asked include: are some team leadership behaviors more critical to a team's level of functioning than other behaviors? and do successful self-managed teams rely on formal leadership to a lesser extent than members of less successful teams? These questions were asked in the context of leadership as a process, not an individual.
Problem-Based Learning for Training Teachers of Students with Behavioral Disorders in Hong Kong: This study attempts to explore the perceived value of Problem-Based Learning (PBL) in training teachers of students with behavioral disorders (E/BD) in Hong Kong. It represents an effort to improve the predominately lecture focussed approach adopted in many preparation programs. Data on the training needs of Hong Kong teachers were also acquired and 31 knowledge/skills areas related to teaching students with E/BD were identified. Subjects viewed the PBL approach as dynamic, interesting and incentive driven. It develops skills involved in group learning, self-directed learning, use of information resources and problem-solving. Most important, teachers felt they were supported to explore the practical problems they personally encountered in the classroom and actions they could take to resolve them. Difficulties in using PBL included a lack of resources and the tendencies of most Chinese students to accept rather than challenge others' ideas.
Perceived Barriers to the Implementation of Site Based Management: The purpose of this study was to identify perceived barriers to the implementation of site-based management for administrators in the Region XII Service Center area in Texas.
Out with the Old? Voting Behavior and Party System Change in Canada and the United States in the 1990's: This study has attempted to explain the dramatic challenges to the existing party system that occurred in Canada and the United States in the early 1990s. The emergence of new political movements with substantial power at the ballot box has transformed both party systems. The rise of United We Stand America in the United States, and the Reform Party in Canada prompts scholars to ask what forces engender such movements. This study demonstrates that models of economic voting and key models of party system change are both instrumental for understanding the rise of new political movements.
Forest Landscape Dynamics: a Semi-Markov Modeling Approach: A transition model (MOSAIC) is used to describe forest dynamics at the landscape scale. The model uses a semi-Markov framework by considering transition probabilities and Erlang distributed holding times in each transition. Parameters for the transition model are derived from a gap model (ZELIG). This procedure ensures conceptual consistency of the landscape model with the fine scale ecological detail represented by the forest gap model. Spatial heterogeneity in the transition model is driven by maps of terrain with characteristics contained in a Geographic Information System (GIS) database. The results of the transition model simulations, percent cover forest type maps, are exported to grid-maps in the GIS. These cover type maps can be classified and used to describe forest dynamics using landscape statistics metrics. The linkage model-GIS enhances the transition model spatial analytical capabilities. A parameterization algorithm was developed that takes as input gap model tracer files which contain the percent occupation of each cover type through time. As output, the algorithm produces a file that contains the parameter values needed for MOSAIC for each one of the possible transitions. Parameters for the holding time distribution were found by calculating an empirical estimate of the cumulative probability function and using a non-linear least squares method to fit this estimate to an Erlang distribution. The algorithm provided good initial estimates of the transitions parameters that can be refined with few additional simulations. A method for deriving classification criteria to designate cover types is presented. The method uses cluster analysis to detect the number and type of forest classes and Classification and Regression Tree (CART) analysis to explain the forest classes in term of stand attributes. This method provided a precise and objective approach for forest cover type definition and classification. The H. J. Andrews forest in Oregon was used to demonstrate the …
A Comparison of the Personality Traits of Effective Teachers of Bilingual and English as a Second Language Students with the Personality Traits of Effective Teachers of Traditional Elementary School Students: The purpose of this study was to identify the personality traits of effective elementary bilingual/ESL teachers, to identify the personality traits of effective traditional elementary teachers, and to compare the two groups.
The Harpsichord Concertos of Wilhelm Friedemann Bach, a Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, W.F. Bach, D. Scarlatti, F. Couperin, J.J. Froberger, G. Ligeti, W. Byrd, and Others: The harpsichord concertos of Wilhelm Friedemann Bach (1710-1784) have suffered undeserved neglect. The four authenticated solo concertos remain in manuscript, with the result that his contribution to the history of the keyboard concerto has been largely overlooked. This study begins to correct this situation by examining these four concertos--F41 in D Major, F43 in E Minor, F44 in F Major, and F45 in A Minor--as well as the published two-harpsichord Concerto in E-Flat Major, F46, and the incomplete Concerto in E-Flat Major, F42 in order to assess W. F. Bach's contribution to the keyboard concerto following its origins in the early 1700s. The results of this investigation show that W. F. Bach took the early keyboard concerto of his father's generation and added many of the characteristics which became associated with the mid-eighteenth century concerto. Friedemann retained the polyphonic interplay between tutti and solo, harmonic language, and tonal plan of his father's compositions and added a wealth of rhythmic ideas and a more modern melodic style. He worked within an established four ritornello/three solo plan for the outer movements, but employed a variety of formal plans for the middle movements. Friedemann heightened the contrast between the solo and the orchestra and infused the solo part with formidable virtuosity. At the same time he ensured that the solo and tutti material was related so that the two forces would work together while maintaining distinct identities. This study shows the high merit of W. F. Bach's harpsichord concertos and adds to another chapter in the history of the pre-Classical keyboard concerto.
George Gershwin's Rhapsody in Blue (Solo Piano Version) : An Historical, Rhythmic and Harmonic Perspective, a Lecture Recital, Together with Three Recitals of Selected Works of R. Schumann, F. Liszt and Others: The evolution of twentieth century American music involves much more than the continuation of European tradition. The music of black Americans before and after the turn of the century had a profound impact on the musical sensibility of American culture in general. Additionally, the fledgling popular music publishing industry had a dramatic effect on the course of "classical" tradition. Nowhere was this more apparent than in the music of George Gershwin. Gershwin's importance in the history of American art music is undisputed. Why his music sounds the way it does is less understood. This paper considers the popular and folk genres that most influenced the young caiposer, and traces specific stylistic elements through their various popular and folk incarnations of the previous thirty years into Gershwin's Rhapsody in Blue of 1924.
Masculine Role Conflict in Gay Men: Mediation of Psychological Well-Being and Help-Seeking Behaviors: Gender role issues have been an integral part of psychology since the 1970s. More recently, theories and research have surfaced concerning the issues of maleness in our society. Most of these theories focus on masculine gender role and how it affects men in various ways, e.g., their psychological well-being, substance use, relational abilities, and help-seeking behaviors. One area of maleness that has consistently been left out of the Masculine Role Conflict (MRC) debate is that of homosexuality. As a gay man develops, he finds himself at odds with society over something that he experiences biologically as normal and appropriate. It is the contention of this paper that MRC is an issue related to psychological distress among gay men and not psychological weakness in gay men, per se.
Interactions of Clean and Sulfur-modified Reactive Metal Surfaces with Aqueous Vapor and Liquid Environments : A Combined Ultra-high Vacuum/electrochemistry Study: The focus of this research is to explore the molecular-level interactions between reactive metal surfaces and aqueous environments by combined ultra-high vacuum/electrochemistry (UHV-EC) methodology. The objectives of this work are to understand (1) the effects of sulfate ions on the passivity of metal oxide/hydroxide surface layer, (2) the effects of sulfur-modification on the evolution of metal oxide/hydroxide surface layer, and (3) the effects of sulfur adsorbate on cation adsorption at metal surfaces.
Factors Related to Student Retention in Community College Developmental Education Mathematics: This study investigated the factors related to student retention in a comprehensive community college developmental education mathematics program. The purpose was to identify and describe these factors and to develop strategies for improving retention in the community college developmental education mathematics program. Tinto's 1975 model of institutional departure was employed to examine different factors relating to retention in developmental education mathematics courses. In accordance with established criteria, data were collected using the Institutional Integration Scale (IIS) and Students Existing Records (SER). The IIS survey instrument questionnaire was completed by 41 students from a sample of 56 developmental education students enrolled in college level mathematics, and the data thus collected were used for analysis. Data were analyzed using frequency count, percentage, and the chi-square statistical analysis with a significant level of 0.05. The analysis of the data showed that the responding sample was primarily white, females aged 18 to 45. Most of the respondents had high grade point averages, did not miss any developmental education mathematics classes, and attended extra curricular activities infrequently. More fathers than mothers of the sample population had received a college education. Academic goal commitment, institutional experience, academic involvement, and placement grades were not statistically significant factors influencing retention. Among the major findings were: Development education instructors appeared to make the difference, institutional experience, academic goal commitment, and placement grades did not appear to play a major role; the students' academic involvement beyond classes appeared negligible; age, gender, grade point average, and parental educational levels were not significant factors for student retention in developmental education mathematics courses. Although statistical evidence did not support reversal of the proposed null hypotheses, pertinent issues for further research were raised.
The Role of the U.S. Mass Media in the Political Socialization of Nigerian Immigrants in the United States: A mail survey of Nigerian immigrants in Dallas, Texas, and Chicago, Illinois, was conducted during October and November 1995. Four hundred and sixty-eight Nigerian immigrant families in the two cities were selected by systematic sampling through the telephone books. Return rate was approximately 40% (187). The variables included in the study were media exposure variables, general demographics, immigration traits, U.S. demographics, Nigerian demographics, and political and cultural traits. New variables which had not been included in previous studies were also tested in this study: television talk shows, talk radio, diffuse support for the U.S. political system, authoritarianism, self-esteem, and political participation. This study employed multiple regression analysis and path analysis of the data. This study found that Nigerian immigrants have high preference for television news as their main source of political information. This finding is in consonance with previous studies. Nigerian immigrants chose ABC news stations as their number one news station for political information. Strong positive associations existed between media exposure and length of stay in the United States and interest in U.S. politics. Talk radio positively associated with interest in U.S. politics and negatively associated with length of stay in the United States. Thus, this finding likely means that talk radio is a good source of political socialization for more recently arrived immigrants and those interested in U.S. politics. Significant associations existed between diffuse support for the U.S. government and interest in politics and security of immigration status. This study also found that adjustment to U.S. political culture was a function of media exposure, pre-immigration social class, diffuse support for the U.S. political system, and political knowledge.
Adsorbate-enhanced Corrosion Processes at Iron and Iron Oxide Surfaces: This study was intended to provide a fuller understanding of the surface chemical processes which result in the corrosion of ferrous materials.
Chronically Ill Children: Maternal Stress and Psychological Symptomatology: This study used a parenting stress and coping model to identify predictors of symptomatology for 13 8 mothers of medically compromised children. This model proposed that: child characteristics (severity of the chronic illness and child related parenting stressors); parent characteristics (self-esteem, sense of competence, and parents' perceived stress/distress); and environmental characteristics (social support, general life stressor events, and demographic variables) contribute to psychological symptomatology for these mothers. Multiple regression analysis found a relationship between general life stressor events, severity of the children's chronic conditions, lower satisfaction with social support, lower self-esteem, and younger mothers' ages and greater symptomatology. Trends toward significance were found for more parenting stress and lower parenting sense of competence predicting greater symptomatology. Predicted relationships between family socioeconomic status and parenting daily hassles and symptomatology were not supported.
Parallels in the Development of Electronic and Percussion Music and an Examination of Performance Problems in Lejaren Hiller's Machine Music for Piano, Percussion and Two-Channel Tape Recorder with Three Recitals of Selected Works of Rolnick, Kessner, Xenakis, Winsor, Niimi, and Others: This study traces the significant developments in the late nineteenth and early twentieth centuries which led to the development of electronic music and increased writing for percussion. Whether by coincidence or premeditation, the field of percussion in Western culture and electronic music share many parallel aspects in their history. Carlos Chavez, Edgard Varese and John Cage foresaw a time when electronic music would allow composers to realize compositions with ease, provide new sounds to the spectrum of possible material for pieces and aid in the conception of works. Significantly, these same composers were important figures in the development of percussion composition. In many ways, Lejaren Hiller's Machine Music can be seen as a culmination of the developments which had been taking place in the history of electronic music and percussion music. A product of the innovations in both fields, it poses some formidable problems for the performers. This study will give some background into its composition, examine its structure and deal with its performance problems.
Selected Factors Associated With Reading Interests of Seventh- and Eighth-grade Pupils: This study sought to determine if there were differences in the types of reading interests of seventh- and eighth-grade pupils associated with their racial origins, their socioeconomic status, or their school environments. It also sought to consider the strength of reading interest scores as related to other variables and to consider the relationship between these scores and the number of hours spent in reading and the change in amount of reading since the previous school year.
The Prediction of Adjustment in Institutionalized Juvenile Offenders: Predictors of institutional adjustment for juvenile offenders were examined using a sample of 120 males in a detention facility. While demographic information failed to differentiate between well and poorly adjusted juveniles, psychological measures appeared to be more effective. Several MMPI-A clinical scales were useful predictors with the overall elevation in clinical scales being one of the strongest predictors. In addition, the Psychopathy Checklist - Clinical Version (PCL-CV) was a strong predictor of adjustment. Major ethnic differences occurred in the prediction of adjustment, with the MMPI-A and PCL-CV scales predicting infraction rates for the African American group but not Anglo American or Hispanic American groups.

Relation of Personal Characteristics to Type of Position Among Bibliographic Network Coordinators, Ex-coordinators, and Selected Library Depeartment Heads: The objectives of this investigation were two-fold. The first was to determine the personal characteristics of Bibliographic Network Coordinators, both past and present; the second was to compare these identified characteristics with those of persons working in traditional library positions at comparable levels of responsibility.
The Impact of Ambiguity and Risk on the Auditor's Assessment of Inherent Risk and Control Risk: The purpose of this study was to try to identify the impact of ambiguity and risk on the auditor's judgment about inherent risk and control risk when planning the audit. A second purpose was to determine how ambiguity tolerance/intolerance affects judgment.
Culture and Anxiety: a Cross-Cultural Study: By measuring interactions among and between anxiety and the independent variables of country of origin, gender, level of education, and age, this study attempted to gain insight into how students from different countries experience anxiety on a U.S. college campus. Results of the Multivariate Analysis of Variance (MANOVA) and the univariate test(ANOVA) indicated that the gender and level of education of the subjects made no significant difference. However, when it came to country of origin, there were significant differences between two of the cultural groups and respective anxiety level. Findings also support a positive correlation between age and anxiety levels, with the youngest participants having the lowest anxiety levels.
A Comparison of a Computer-Administered Test and a Paper and Pencil Test Using Normally Achieving and Mathematically Disabled Young Children: This study investigated whether a computer-administered mathematics test can provide equivalent results for normal and mathematically disabled students while retaining similar psychometric characteristics of an equivalent paper and pencil version of the test. The overall purpose of the study was twofold. First, the viability of using computer administered assessment with elementary school children was examined. Second, by investigating items on the computer administered mathematics test for potential bias between normally achieving and mathematically disabled populations, it was possible to determine whether certain mathematical concepts consistently distinguish between the two ability groups.

Alternative Funding Models for Financing Construction of Public School Facilities and Debt Retirement: The main purpose of this study was to examine the various finance models that are presently being used to finance facilities and to provide information for the Texas legislature, the Texas Education Agency, and local school districts concerning facilities funding models that might be used in Texas. Based on the information gathered and analyzed, several conclusions are drawn and recommendations regarding state funding of capital projects in the State of Texas are made. The model recommended for Texas is one that provides for an equalized grant and includes formulas for the distribution of state money.
How Computer Use Functions as an Aspect of Literacy Development : A Qualitative Description of a Second-grade Classroom: In this study, the researcher investigated how computer use functions as an aspect of literacy development within a second-grade classroom. The researcher sought to gather data to help define the role that computer use plays in the literacy development of elementary school students by concentrating on how computers are actually used in the classroom being studied, and by looking for relationships revealed by students' and teacher's beliefs about computer use in the classroom.
Theological Distance Learning through Trinity College and Theological Seminary: Programs, Problems, Perceptions, and Prospects: An international survey was conducted to assess theological higher education via distance learning as perceived by graduates of Trinity College and Theological Seminary's (Trinity) doctoral programs. The purpose of the study was to determine student-perceived strengths and weaknesses of Trinity's doctoral-level distance education theology programs. Also, the future of distance-learning mediated programs of theological higher education was speculated. A random sample of 400 doctoral recipients was selected from the population of 802 doctoral recipients who graduated from Trinity between the years of 1969 and March 1998. A mailed questionnaire was used to collect data. A total of 203 (50.0%) were returned. Frequency counts, percentage distributions, and chi-square tests of goodness-of-fit were employed to analyze the data. A profile of the modal type of student who would participate in theological distance education at the doctoral level was developed from the demographic variables queried. Responses to questions regarding respondents' educational experiences and coursework were solicited as well. Respondents identified five primary strengths of Trinity's distance education doctoral programs as: the convenience of the program; the immediate application of course content to personal and professional endeavors; the quality of education provided; the Biblical groundedness of the curricula, the materials, and the faculty; and the required reading and research. The three predominant weaknesses of Trinity's distance education doctoral programs as identified by program graduates include: the lack of interaction between students and faculty; the lack of regional accreditation; and course repetitiveness meaning that some courses offered repeated content from prior studies at a lower educational level. It was concluded that the future of theological higher education via distance learning is promising. Trinity has emerged as a dominant distance learning institution as a result of its continued exploration and advancements. However, Trinity and other similar distance education institutions must continually and consistently evaluate their programs …
Universal Branched Coverings: In this paper, the study of k-fold branched coverings for which the branch set is a stratified set is considered. First of all, the existence of universal k-fold branched coverings over CW-complexes with stratified branch set is proved using Brown's Representability Theorem. Next, an explicit construction of universal k-fold branched coverings over manifolds is given. Finally, some homotopy and homology groups are computed for some specific examples of Universal k-fold branched coverings.
