Adolescent Pregnancy: Voices Heard in the Everyday Lives of Pregnant Teenagers: The purpose of this study is to examine the problems that pregnant teenagers encounter at school and at home while they are trying to complete their high school education. Data were collected by in-depth interviews. Twenty pregnant adolescents, who were between the ages of 15 through 18, and were participants in a special teen pregnancy program were interviewed. The major findings in this study included the respondents': 1) unstable family life histories, 2) denial that they were pregnant, 3) need for self-identity as an adult, 4) conflict with parents and 5) motivation to complete their high school education. This study points to the need for more research on the problems that pregnant adolescents encounter in their everyday lives.
An Algorithm for the PLA Equivalence Problem: The Programmable Logic Array (PLA) has been widely used in the design of VLSI circuits and systems because of its regularity, flexibility, and simplicity. The equivalence problem is typically to verify that the final description of a circuit is functionally equivalent to its initial description. Verifying the functional equivalence of two descriptions is equivalent to proving their logical equivalence. This problem of pure logic is essential to circuit design. The most widely used technique to solve the problem is based on Binary Decision Diagram or BDD, proposed by Bryant in 1986. Unfortunately, BDD requires too much time and space to represent moderately large circuits for equivalence testing. We design and implement a new algorithm called the Cover-Merge Algorithm for the equivalence problem based on a divide-and-conquer strategy using the concept of cover and a derivational method. We prove that the algorithm is sound and complete. Because of the NP-completeness of the problem, we emphasize simplifications to reduce the search space or to avoid redundant computations. Simplification techniques are incorporated into the algorithm as an essential part to speed up the the derivation process. Two different sets of heuristics are developed for two opposite goals: one for the proof of equivalence and the other for its disproof. Experiments on a large scale of data have shown that big speed-ups can be achieved by prioritizing the heuristics and by choosing the most favorable one at each iteration of the Algorithm. Results are compared with those for BDD on standard benchmark problems as well as on random PLAs to perform an unbiased way of testing algorithms. It has been shown that the Cover-Merge Algorithm outperforms BDD in nearly all problem instances in terms of time and space. The algorithm has demonstrated fairly stabilized and practical performances especially for big PLAs under a wide …
An Analysis of Factors That Influence the Involvement of Faculty in Learning Communities: This research study attempts to analyze variables that influence the extent of faculty involvement in learning communities. A theoretical framework identifies three primary variable sets—faculty background, structural, and organizational/environmental.
Anxiety, Locus of Control and Stress in Adoptive and Biological Parents of Adolescents: The purpose of this study was to critically examine differences in levels of anxiety, locus of control and stress between adoptive and biological parents of adolescents.
An Argument for the Reassessment of Stravinsky's Early Serial Compositions: Between 1952 and 1957, Igor Stravinsky surprised the world of music by gradually incorporating serialism into his style of composition. Although Stravinsky still used the neo-classical trait of making strong references to the music of earlier periods, musical analyses of this transitional period have focused on serial aspects to the exclusion of anachronistic elements. Evidence of Stravinsky's possible use of musical structures adapted from earlier times is found in his consistent use of musical figures that are closely related to the cadences of the late Medieval and Renaissance eras. By fully addressing these neo-classical traits in future analyses, music theorists will gain an additional perspective, which is helpful in understanding the music of Stravinsky's transitional period.
The Arrangement of Ezra Pound's Personae (1926) : An Interpretive Application of Editorial and Critical Theory: Pound foregrounded the importance of "shaping" poetic books through particular arrangements of individual poems by using his ideogrammic method as the crucial organizational principle for constructing Personae (1926). Critics have long understood Pound's use of the ideogrammic method in individual poems, but have so far ignored his application of it to the structuring of poetic books and sequences. Lea Baechler and A. Walton Litz, the editors of a 1990 edition of Personae (1926), however, have moved a crucial section of poems, and their rearrangement of the original text both disregards evidence of authorial intention and obscures Pound's innovative principles for arranging his shorter poems into meaningful sequences.
The Assessment of Cognitive Functioning of Persons with Schizophrenia: Identification of Neuropsychological Markers: The present study was conducted to clarify and expand knowledge of cognitive functioning in chronic schizophrenia patients (N=21) as compared to a bipolar group (N=20) and a normal group (N=20).
An Assessment of Learning Outcomes of Students Taught a Competency-Based Computer Course in an Electronically-Expanded Classroom: This study sought to determine whether there was a difference in subject matter knowledge as measured by a pretest and posttest, a difference in final course grade as a numeric score, and a difference in attitudes toward computers between students in a competency-based ("hands-on") computer applications course taught in an electronically-expanded classroom compared to students taught in a traditional classroom setting. In addition, students taught in the electronically-expanded classroom completed a questionnaire assessing attitudes toward the presentation method. Another purpose of this study was to evaluate the feasibility of applying distance education techniques to teach what was, in essence, an on-campus course. The vehicle for this investigation was an electronically-expanded classroom. The electronically-expanded classroom utilized distance education technology (video, audio, and computer networking) to connect two classrooms in the one building. Students in these two classrooms were the treatment group. Students taking the course in a traditional setting functioned as the comparison group. A total of 109 participants completed the study. Results of the study revealed no significant difference in scores on the subject matter posttest, the final course grade as a numeric score, and attitudes towards computers posttest between students taught the course in an electronically-expanded classroom and students taught the course in the traditional classroom. Results of the survey to measure satisfaction with the presentation method revealed that students in the receive room were slightly more satisfied than students in the send room with the presentation method, but the difference was not significant. The survey indicated that participants in the study were sensitive to technical problems, especially audio-related difficulties. While participants noted some dissatisfaction with audio quality, it had no apparent effect on learning outcomes and attitudes for this study. The study concluded that students taking a course in an electronically-expanded classroom have learning outcomes and attitudes toward …
Attention and Information Processing Variables in Hypothetically Psychosis-Prone College Students: Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment than would the more molecular tasks. The results of the study did not support the hypotheses as there were no significant differences between the schizotypy group and the nonschizotypy group and the measures of a more molar nature did not better predict social adjustment. Further research might consider increasing the sample size, applying more stringent cut-off criteria for the schizotypy group, and verifying the validity of using PER-MAG, COGLAB, and PAS with this population. Further research also needs to clarify the ways in which those identified as psychosis-prone process information like (or unlike) nonschizotypes and how their current social functioning …
Attributional Style as a Predictor of Academic Success for Students with Learning Disabilities and Attention Deficit Disorder in Postsecondary Education: Thirty one students with learning disabilities (LD) and/or with Attention Deficit Hyperactivity Disorder (ADHD) completed a combined Academic Attributional Style and Coping with Academic Failures Questionnaire. The reformulated learned helplessness model (Abramson, Seligman, & Teasdale, 1978) predicted that students with negative attributional styles (i.e., internal-stable-global attributions) experienced motivational, cognitive, and emotional deficits. The present study examined college achievement (grade point average) of students with LD and/or ADHD. The Prediction that students with LD and/or ADHD with negative attributional styles would achieve less academic success than comparable students with positive attributional styles (i.e., extenal-unstable-specific attributions) was supported by the research results.
Benjamin West's St. Paul Shaking the Viper from his Hand After the Shipwreck: Altarpiece of 1789 and Designs for Other Decorative Works in the Chapel of St. Peter and St. Paul, The Royal Naval College, London: This thesis analyzes Benjamin West's altarpiece St. Paul Shaking the Viper from His Hand After the Shipwreck and his designs for thirty-three related artworks in the Royal Naval College Chapel, Greenwich, England, as a synthesis of the major influences in his life and as an example of both traditional and innovative themes in his artistic style of the late eighteenth century. This study examines West's life, the Greenwich Chapel history, altarpiece and decorative scheme, and concludes that the designs are an example of West's stylistic flexibility and are related thematically to his Windsor Royal Chapel commission.
Biodegradation of Certain Petroleum Product Contaminants in Soil and Water By Selected Bacteria: Soil contamination by gasoline underground storage tanks is a critical environmental problem. The results herein show that in situ bioremediation using indigenous soil microorganisms is the method of choice. Five sites were selected for bioremediation based on the levels of benzene, toluene, ethylbenzene and xylene and the amount of total petroleum hydrocarbons in the soil. Bacteria capable of degrading these contaminants were selected from the contaminated sites and grown in 1,200 I mass cultures. These were added to the soil together with nutrients, water and air via PVC pipes.
Brain Topography of Leadership: Neurophysiological Correlates of the Leadership Opinion Questionnaire: Laboratory research was performed to understand leadership by attempting to link EEG baseline frequency patterns with data from the Leadership Opinion Questionnaire (LOQ) assessment survey. Research began with 293 right-handed males, 18 to 26 years-old, who completed the LOQ. Based on their scores, 61 subjects, grouped by the Ohio State Leadership Quadrants, were tested using brain-mapping technology.
Bureaucracy and the Mexican American Elderly: Utilization of Formal and Informal Social Services: Using the National Survey of Hispanic Elderly People, 1988, this study examines the support system of the Mexican American elderly and their utilization of formal social services. Two major research questions were addressed: 1) How does the Mexican American family provide assistance to their elderly family members? and 2) How does the bureaucratic structure affect the Mexican American elderly's access and utilization of formal social services?

Written for the Copenhagen Wind Quintet in 1922, it is also considered a pivotal composition in Nielsen's artistic output. This treatise offers a brief biography of Carl Nielsen, documents the history and significance of the Quintet for Winds, Op. 43, and presents a critical edition that will enable more accurate performances of this important composition.
Cell-Free Recovery and Isotopic Identification of Cyanide Degrading Enzymes from Pseudomonas Fluorescens: Cell-free extracts from Pseudomonas fluorescens NCIMB 11764 catalyzed the degradation of cyanide into products that included C02, formic acid, formamide and ammonia. Cyanide-degrading activity was localized to cytosolic cell fractions and was observed at substrate concentrations as high as 100 mM. Two cyanide degrading activities were identified by: (i) the determination of reaction products stoichiometries, (ii) requirements for NADH and oxygen, and (iii) kinetic analysis. The first activity produced CO2 and NH3 as reaction products, was dependent on oxygen and NADH for activity, and displayed an apparent Km for cyanide of 1.2 mM. The second activity generated formic acid (and NH3) pfus formamide as reaction products, was oxygen independent, and had an apparent Km of 12 mM for cyanide. The first enzymatic activity was identified as cyanide oxygenase whereas the second activity consists of two enzymes, a cyanide nitrilase (dihydratase) and putative cyanide hydratase. In addition to these enzymes, cyanide-grown cells were also induced for formate dehydrogenase (FDH), providing a means of recycling NADH utilized by cyanide oxygenase.
Characterization of Tolerance and Cross-tolerance between Noncompetitive N-methyl-D-aspartate (NMDA) Antagonists in Rats Trained to Self-administer Ketamine: Ketamine and phencyclidine (PCP) are noncompetitive antagonists of the N-methyl-D-aspartate (NMDA) type of ligand-gated glutamate receptors. Both agents have high abuse liability, and may produce dependence. Tolerance to the reinforcing effects of drugs of abuse is widely regarded as a key component of the dependence process. Therefore, the present study was conducted to examine whether tolerance develops to the reinforcing effects of ketamine, and whether PCP and dizocilpine, a noncompetitive NMDA antagonist with negligible abuse liability, produce cross-tolerance to the reinforcing effects of ketamine. Further, identification of the neural mechanisms that underlie tolerance to the reinforcing effects of drugs may yield information regarding drug dependence.
College Students at Risk of Academic Failure: Neurocognitive Strengths and Weaknesses: This study examined the neurocognitive skills, incidence of mild head injury, incidence of learning disabilities, and study habits among college students with grade point average of 2.00 or below (N = 25) as contrasted with college students with grade point average above 2.00 (N = 70). The intent of this research was to extend the work of Segalowitz and Brown (1991) and Segalowitz and Lawson (1993) who found significant associations between reported history of mild head injury and developmental disabilities among high school and college samples. MANOVAs conducted on measures of academic achievement, global cognitive skills, verbal and nonverbal memory, motor and tactile functioning, and study habits did not discriminate between probationary and non-probationary students. Probationary and non-probationary students also did not differ with regard to incidence of reported head injury, frequency of diagnosed learning disabilities, and study habits. Measures of neurocognitive functioning and study habits did not contribute to the prediction of grade point average over and above that predicted by Scholastic Aptitude Test composite score. Several exploratory analyses were performed examining the relationship between study habits and neurocognitive skills. Gender differences, implications for future research and development of study skills courses, and limitations of this study were discussed.
A Communication Based Model of Power: We are affected greatly by power, and often do not understand what power is, how it is used, and its many other facets. Power and communication are interrelated, but how they relate to each other has been hard to understand. The model presented in this thesis explicates the relationship between the two critical variables. Power is portrayed as a hierarchical structure that is based on influence (communication) where the intensity and likelihood of success of power attempts increase as the level of power increases. The hierarchical structure has four levels, including influence at its base, and prominence, authority and control at the higher levels.
A Comparative Analysis of the Effects of Video-Based versus Live Presentation Staff Development on Teachers' Cognitive Learning and Attitudes: The problem of this study was the identification of effective and efficient means of providing quality staff development for reading instruction within a school-district setting. The study investigated the comparative effectiveness of two staff development delivery systems measured by 1) a cognitive test of a school district's reading program and 2) an affective measure of teacher attitudes toward staff development. The sample was drawn from the teacher population of a large urban school district. The 46 subjects were elementary school teachers in grades K-5 randomly divided into two groups: Group A (videotape with a trained on-site facilitator) and Group B (face-to-face live presenter). Participants in the study received training using "The Fort Worth Reading Program," a staff development program designed by the researcher. In addition to the presentation of content information, which is the central component, the program features small group discussions, off-line activities, and question and answer periods. Both groups received the same treatment with the following exception. A central component to the Group A training was the presentation of content information in a videotape format. Group B did not view the videotape, but received the same information via live presenter. Two instruments developed by the researcher were used in the study: 1) The Teacher Staff Development Questionnaire, a Likert-type survey to obtain teacher attitudes toward staff development, and 2) The Cognitive Test of Reading Knowledge, an instrument designed to measure cognitive objectives of the district's reading program. A multivariate analysis of covariance revealed no statistically significant differences between the groups. It was concluded that elementary classroom teachers, regardless of their attitudes toward staff development, learn content material equally well with either of the two delivery systems explored in this study. Specific suggestions and recommendations for further studies are addressed and discussed. Examples of the measurement instruments are included.
A Comparison of Knowledge and Attitudes between Directors of Athletics and Head Trainers in the Southwest and Southland Conferences Regarding HIV-transmission Issues in Athletics: The purpose of this study was to investigate and compare knowledge and attitudes of directors of athletics and head trainers in the Southwest (Division 1A) and the Southland (Division 1AA) Conferences concerning HIV/AIDS issues related to transmission, prevention, and protection within college athletics programs. The results of this qualitative study provided descriptive data from university administrators within the athletics setting who are responsible for providing adequate student athlete health care services from developed and implemented administrative policies that directly or indirectly affect a student athlete's physiological and psychological well-being.
Concertino for Flute, Timpani and String Orchestra: Concertino for Flute, Timpani, and String Orchestra is a three movement piece that blends Western European forms with Korean idioms. The following essay addresses pitch materials, melodic structure, rhythm, form, instrumentation, vertical structures, and developmental procedures used in the work.
Convexity-Preserving Scattered Data Interpolation: Surface fitting methods play an important role in many scientific fields as well as in computer aided geometric design. The problem treated here is that of constructing a smooth surface that interpolates data values associated with scattered nodes in the plane. The data is said to be convex if there exists a convex interpolant. The problem of convexity-preserving interpolation is to determine if the data is convex, and construct a convex interpolant if it exists.
A Correlational Study Using the Behavior Dimensions Rating Scale & the Behavior Assessment System for Children with Two Groups of Elementary School-Aged Students in Special Programs: This study examined the correlation between two commercially available behavior rating scales. The two scales used were the Behavior Dimensions Rating Scale (BDRS) and the Behavior Assessment System for Children (BASC). Students from a special education behavior management class (primarily students with emotional disabilities) were rated on the two scales and students from a general education behavior management class (primarily students with conduct problems without disabilities) were rated on the two scales.
Cost of Issuing Debt: An Analysis of the Factors Affecting the Net Interest Cost of State Bonds: The major purpose of this dissertation is to explore the determinants of interest cost for state bonds. Various kinds of variables pertaining to issue characteristics, market characteristics, economic conditions, and political variables were statistically tested to assess their impact on the interest cost of state bonds. This research examines the variables found to be significant for local bonds, as well as some factors unique to state bonds, e.g., the types state agencies issuing debt and the effect of different state income tax policies.
A Cross-Sectional Study of Custodial Grandparenting: Stresses, Coping Skills, and Relationships with Grandchildren: This cross-sectional study compared three groups of grandparents, two custodial and one noncustodial, to identify and delineate the unique challenges and expectations faced by custodial grandparents due to their nontraditional roles while attempting to disentangle grandparental role demands from child-specific problems as sources of distress. Those grandparents raising grandchildren demonstrating neurological, physical, emotional, or behavioral problems exhibited the most distress, the most disruption of roles, and the most deteriorated grandparent-grandchild relationships. Although the custodial grandparents raising apparently normal grandchildren demonstrated less distress, less disruption of roles, and less deterioration of the grandparent-grandchild relationship than those grandparents raising grandchildren displaying problems, they still demonstrated higher levels than did traditional grandparents. Those grandparents who reported fewer resources, demonstrated poor attitudes regarding seeking mental health services, and reported raising grandchildren displaying problems had the lowest levels of adjustment.
Cultural Differences in Pain Experience and Behavior among Mexican, Mexican American and Anglo American Headache Pain Sufferers: Review of previous research on cultural differences in pain experience and/or pain behavior revealed that cultural affiliation affects pain perception and response. Unfortunately, the many inconsistent findings in the literature on cultural differences in pain experience and behavior have made interpretations and comparisons of results problematic. These inconsistent findings could be attributed to variations in acculturation level among cultural groups. The purpose of this study was to investigate cultural differences in pain experience (assessed by McGill Pain Questionnaire, the Box Scale, the Headache Pain Drawing, and the Headache Questionnaire) and pain behavior (measured by determining medication use and interference of daily functioning due to headaches) among Mexican (n = 43), Mexican American (n = 36), and Anglo American (n = 50) female chronic headache pain sufferers. The contribution of acculturation to differences in pain experience and behavior among cultural groups was measured by the Acculturation Rating Scale for Mexican Americans. The three cultural groups of women significantly differed on pain experience and pain behavior. Specifically, Mexican women experienced their headache pain more intensely, severely, and emotionally than Mexican American and Anglo American women. Furthermore, Mexican women were more willing to verbally express their pain than the other two groups. As for pain behavior, Mexican women took more medication and reported more severe inhibition of daily activities due to headaches than Mexican American and Anglo American women. Ethnic identity, ethnic pride, and language preference were factors in the acculturation process which contributed the most to women's chronic pain experience and behavior. The greatest variability occurred within the Mexican American group of women who perceived themselves as being more Mexican in attitudes and/or behaviors, but more similar to Anglo American in their pain experience and pain behavior. Results are explained using biocultural multidimensional pain theory, social learning theory, and acculturation theory.
The Cultural Politics of Baldur von Schirach, 1925-1940: This thesis examines the career of Baldur von Schirach, who headed the National Socialist Students' Union from 1928 to 1931 and the Hitler Youth from 1931 until 1940.
Daniel's Battery: A Narrative History and Socio-Economic Study of the Ninth Texas Field Battery: This thesis combines a traditional narrative history of a Confederate artillery battery with a socio-economic study of its members. A database was constructed using the Compiled Service Records, 1860 census, and county tax rolls. The information revealed similarities between the unit's members and their home area. Captain James M. Daniel organized the battery in Paris, Texas and it entered Confederate service in January 1862. The battery served in Walker's Texas Division. It was part of a reserve force at the Battle of Milliken's Bend and was involved in the battles of Bayou Bourbeau, Mansfield, and Pleasant Hill. The battery also shelled Union ships on the Mississippi River. Daniel's Battery officially surrendered at Natchitoches, Louisiana, in May 1865.
Designing a Social Marketing Plan to Promote Hispanic Participation at Prostate Cancer Screenings: Prostate cancer is the most commonly occurring cancer and the second leading cause of cancer death for men in the United States. Because early prostate cancer is frequently without symptoms and data on how to prevent prostate cancer is lacking, early detection has the greatest potential for decreasing mortality. Studies have shown Hispanics/Latinos to be less likely than whites or African-Americans to utilize prostate cancer screening exams. The purpose of this descriptive study was to design a social marketing plan which could be used as a model to promote Hispanic/Latino participation at prostate cancer screenings. Information obtained through medical and marketing literature review, the author's experiences serving on the promotion committee of a community-sponsored prostate cancer screening project, and interviews with 51 Hispanic/Latino prostate cancer screening participants is described and incorporated into a guide with recommendations for future program planners.
Differences in Marketing Mainstream and Independent Feature Films in the United States (1990-1995): The purpose of this study is (1) to examine mainstream studio films and their marketing (2) to examine independent films and their marketing (3) to explore the marketing challenges of independent films (4) to explore new developments in independent film and the emergence of crossover films (5) to explore the benefits of alliances between the major studios and independent film distributors (6) to examine the diminishing differences between major studio films and independent films.
Do Non-Native Grammars Allow Verbs to Raise to Agreement?: The purpose of this thesis is to determine whether the setting of the verb movement parameter in L2 is dependent on agreement acquisition. The Optionality hypothesis (Eubank, 1994) is tested by examining the L2 grammar of Chinese learners of English. To test this hypothesis, the sentence matching procedure originally described in Freedman and Forster (1985) is used. It is found that no current theory truly accounts for the results that are obtained.
The Dostoevskyan Dialectic in Selected North American Literary Works: This study is an examination of the rhetorical concept of the dialectic as it is realized in selected works of North American dystopian literature. The dialectic is one of the main factors in curtailing enlightenment rationalism which, taken to an extreme, would deny man freedom while claiming to bestow freedom upon him. The focus of this dissertation is on an analysis of twentieth-century dystopias and the dialectic of Fyodor Dostoevsky's Grand Inquisitor parable which is a precursor to dystopian literature. The Grand Inquisitor parable of The Brothers Karamazov is a blueprint for dystopian states delineated in anti-utopian fiction. Also, Dostoevsky's parable constitutes a powerful dialectical struggle between polar opposites which are presented in the following twentieth-century dystopias: Zamiatin's Me, Bradbury's Farenheit 451, Vonnegut's Player Piano, and Atwood's The Handmaid's Tale. The dialectic in the dystopian genre presents a give and take between the opposites of faith and doubt, liberty and slavery, and it often presents the individual of the anti-utopian state with a choice. When presented with the dialectic, then, the individual is presented with the capacity to make a real choice; therefore, he is presented with a hope for salvation in the totalitarian dystopias of modern twentieth-century literature.
Early Communicative Behaviors in a Two Year Old Child with a Cochlear Implant in an Auditory-Verbal Program: The communicative interchanges of a congenitally deaf child who received a cochlear implant at 24 months of age were videotaped in fifteen hourly sessions over a nine month period while she participated in auditory-verbal therapy prior to and following implantation. The present study examined selected early communicative behaviors. Using Tait's (1993) protocol for charting communicative adult-child interaction, gestures, eye-gaze, and sound uttered either by the child or an adult during communicative interchanges were transcribed from the videotapes. Results corresponded with Tait's, revealing growth in the child's communicative interaction across sessions. In less than three months following implantation phonemic measures rose dramatically. Almost all phonemic measure correlations were significant, high, and positive.
The Eclectic Paradigm of Salesperson Compensation: a New Framework for Investigating the Role of Salary versus Commission: Numerous researchers, employing theories from either psychology or economics, have investigated the circumstances under which firms are likely to adopt salary-based versus commission-based compensation plans. This study integrates the most common theoretical bases of salesperson compensation literature into a broad framework labeled the Eclectic Paradigm of Salesperson Compensation (EPSC). The EPSC proposes that there is a positive association between a firm's salary orientation and resource commitment, and a firm's salary orientation and firm control. There should be a negative association between salary orientation and dissemination risk, and salary orientation and salesperson motivation/performance. Twenty-three hypotheses originating from the EPSC were tested using a pretest sample of 48 real estate salespersons and a test sample of 311 real estate salespersons. The data were analyzed using common factor analysis, logistic regression, multivariate analysis of variance, and median tests. Of the 23 hypotheses, 10 were supported, 7 were partially supported, and 6 were not supported. The results suggest that the eclectic paradigm of salesperson compensation is a promising initial step toward developing a comprehensive model for understanding the determinants of salary versus commission.
The Effectiveness of Institutionalization of a Curricular Change in Department of Defense Dependents' Schools: In this study factors which affect the degree of implementation of a curricular change were examined to determine how well a specific curricular change was implemented in relation to the original intent. The change, Developmentally Appropriate Practice, was implemented in Department of Defense Dependents Schools, Germany Region, beginning in school year 1991-1992 in grades kindergarten through two. During school year 1993-1994, grade three began the transition to Developmentally Appropriate Practice. Several factors which influence teacher behavior during the implementation process were investigated to determine if there is a correlation between those factors and degree of implementation, the dependent variable. The independent variables in this study were school culture; administrators' leadership effectiveness; teacher concerns about the implementation; and teacher characteristics including age, years teaching experience, years experience in Department of Defense Dependents' Schools, and training. The degree of implementation, the dependent variable, was defined in terms of the extent to which teachers had changed their behavior to become congruent with behavior required by the change. Teachers were identified as high, moderate, or low implementers, based on classroom observations. One purpose of the study was to increase understanding of implementation by analyzing the factors which affect the behavior of teachers in the change process. A second purpose of the study was to add to the body of research that explains why so many educational changes fail to become established practice. To establish interobserver reliability, two observers rated teachers using the same protocol. The interobserver reliability coefficient found was reported at .9820. The participants in the study completed the Stages of Concern Questionnaire, the Administrative Effectiveness Survey, the School Culture Survey, and a demographic survey. The results were correlated with the Early Childhood Classroom Observation form. Amount of training was found to have a statistically significant positive relationship with degree of implementation (p=.006). …
The Effects of Computer Intensive Classwork on the Critical Thinking Skills of Community College Students: To determine the relationship between computer intensive classwork and change in critical thinking skills exhibited by college students, the Watson-Glaser Critical Thinking Appraisal, which generates Inference, Assumptions, Deduction, Interpretation, Arguments, and Total scores, was administered as pretest and post-test to students enrolled in four sections of a freshman level writing class at a community college, where two sections each were taught by computer intensive (computer) and traditional (non-computer) methods. Students completed a Demographic Questionnaire regarding previous computer experience, gender, and ethnicity. Where available, reading skills information was obtained from college records.
Effects of External Electric Fields on Light Transmittance in Isolated Crayfish Nerves: Acute effects of a pulsed external electric field (PEEF) at 20 V/cm and a d.c. EEF at 90 V/cm on light transmittance in an isolated compound crayfish nerve was measured. In a third series, the nerve was pre-treated with the Na+ channel blocker tetrodotoxin (TTX). A PEEF produced an irreversible increase in the variation of light transmittance in normal nerves but a reversible increase in TTX treated nerves. This data was statistically insignificant. The d.c. EEFs produced a reversible and statistically significant enhancement of variation in light transmittance in both untreated and TTX-treated nerves. The findings may be due to either (1) an alteration in the ion/fluid flux within the nerve or (2) a physical alteration of protein molecules in the membranes.
An Examination of the Presence of Schön's Concept of "Reflective Conversation" as a Defining Component in the Applied Studio Music Lesson: The purpose of this study was to examine the presence of Schön's concept of reflective conversation as a defining component in the applied studio music lesson. The research problems were (1) to determine the presence of complete and incomplete reflective conversations; (2) to determine the verbally exhibited knowledge base within complete conversations in relationship to conversation length; and (3) to establish an instructional profile of stable behaviors based on reflective conversation as a distinguishing characteristic among selected teachers. Videotapes of twenty-six applied studio music lessons of thirteen university teachers were analyzed according to problem solving, on-the-spot experimentation, and evaluation. An observation form was developed and was a reliable tool to collect information concerning number and type of reflective conversations, conversation length, and the teachers' verbally demonstrated knowledge base. Knowledge base was obtained by using the procedural model of Flanagan's critical incident technique. Reflective conversations existed and were a distinguishing characteristic of the teachers. With the exception of two teachers, a stable use of both number and length of reflective conversations, and knowledge base areas, was found. A discernible difference in the teachers' knowledge base within conversation length existed, and thus established instructional profiles for the teachers. Complete reflective conversations ranged from one-sixth to over half of total lesson time. Within instrument categories, teachers generally revealed a dissimilar knowledge usage. Some teachers exhibited fast-paced problem solving, in one minute or less, and named one or two knowledge areas. Others had longer conversations, up to five minutes, with more deliberate problem solving, and as many as twelve knowledge areas named. Results indicated that a practically significant situation can be examined by establishing teacher instructional profiles based upon reflective conversation. Methods employed in this study could be used to document teacher problem-solving and teacher knowledge in a variety of settings.
Graduate Students' Perceptions of the Effectiveness of a Two-Way Audio/Video Distance Learning Session and of Its Effects on Graduate Students' Comfort Level: The purposes of this study were to (a) determine graduate students' perceptions of the effectiveness of the delivery system and their level of comfort with the delivery system, (b) determine graduate students' perceptions of the effectiveness of the delivery system and their level of comfort with the teacher, (c) determine graduate students' level of comfort with the delivery system and their level of comfort with the teacher, (d) determine differences in graduate students' ratings of the effectiveness of the delivery system before a distance education session and after a distance education session, and (e) determine differences in graduate students' level of comfort with the teacher before a distance education session and after a distance education session.
How Adult Readers Navigate Through Expository Text in a Hypermedia Environment to Construct Meaning: Research methods from both the qualitative and quantitative paradigms were used to answer the question concerning how adult readers navigate through informational text embedded in a hypermedia environment to construct meaning.
India Vaale in the United States: This documentary reveals the thoughts and feelings of seven Indian students at the University of North Texas, Denton, Texas. It portrays that better material comforts in the U.S. condition the decision of Indian students in not returning to India even after the completion of their studies. It also shows their feelings of nostalgia for the social and cultural milieu of their home country, India. For this project 18 Indian students at the University of North Texas were interviewed and seven of them became part of the final documentary.
Interactions Between Texts, Illustrations, and Readers: The Empiricist, Imperialist Narratives and Polemics of Sir Arthur Conan Doyle: While literary critics heretofore have subordinated Conan Doyle to more "canonical" writers, the author argues that his writings enrich our understanding of the ways in which Victorians and Edwardians constructed their identity as imperialists and that we therefore cannot afford to overlook Conan Doyle's work.

Memory Functions among Children Irradiated for Brain Tumor: Children who have received radiation therapy for the treatment of brain tumors have been shown to experience neurocognitive deficits which appear to increase over time. The purpose of this study was to examine the memory functioning of 22 children irradiated for brain tumor and 22 healthy children of the same age who had not received irradiation. Subjects were administered a brief form of the WISC-III, to obtain an IQ, and the Wide Range Assessment of Memory and Learning (WRAML), to evaluate visual and verbal memory. Results indicated that, although there were no significant differences between the IQ scores of healthy children and children who had been irradiated, children who have received radiation therapy for brain tumor evidence memory deficits which effect visual and verbal memory abilities. Among the children who had been irradiated, as time since treatment increased, visual memory and overall memory functioning appeared to decline. Findings also suggested that children who received total tumor resection may evidence greater memory deficits than those who received only a partial resection. Visual memory was more closely related to IQ in the children irradiated for brain tumor than in the healthy children. The overall importance of research with this population lies in refining the understanding of memory deficits and strengths in order to formulate more effective remediation compensation, strategies.

Municipal Bond Ratings and the Willingness to Issue Debt: A Pooled Cross-sectional Analysis of Texas Cities: This dissertation deals with one aspect of how city officials respond to community needs. It is about the decisions of governments on how to secure the financial resources needed to fulfill their obligations to the public. The study explores the factors that influence officials' decisions to issue debt. It is different from other municipal bond studies in that it focuses on the behavior of bond issuers rather than bond investors and the rating agencies.

Parenting Stress and the Family Environment of Mothers Who Have Returned to College: Stress plays a key role in our daily lives, influencing our emotional state, productivity, and health. One particular role in life, being a parent, has attracted significant attention in the research world in terms of the amount of stress parents experience in relation to different aspects of being parents. A life change that many parents, particularly mothers, are experiencing in increasing numbers is their return to college. This study compared reports of parenting stress and perceptions of the family environment between two groups of mothers. The first is a group of 32 mothers who were working 30 or more hours a week outside the home and were not enrolled in college while the second group consists of 31 mothers who were in college full-time and working less than 10 hours a week outside the home. All of the mothers were between the ages of 25 and 45 and had at least one child between the ages 5 and 12 years old. In both groups the mothers verified that their child(ren) was (were) without any diagnosis of an emotional, behavioral, or learning problem. A series of one-way multivariate analysis of variance (MANOVAs) were performed. Results indicated there were no significant group effects related to the overall parenting stress expressed by the mothers. A significant group effect was noted (F = 5.31;\ p < .05) in that the working mothers reported a greater level of perceived poor health than the mothers who were attending college full-time. In relation to the mothers' perception of their family environment, a significant group effect (F = 6.23;\ p < .05) was found indicating that the working mothers reported a greater emphasis on ethical and religious issues and values.
