First Impressions of Therapists: the Effect of Therapist Gender, Gaze, Smiling and Subject Gender
Conceptualization psychotherapy as an interpersonal influence process emphasizes how a therapist is perceived by a client. Factors affecting a client's early impressions of a therapist could influence therapeutic interactions since first impressions are relatively stable. The study investigated effects of nonverbal behavior and gender during a simulated initial meeting between a therapist and client. Undergraduates (N = 466) viewed a male or female therapist interviewing with a new female client. Therapist gaze .(100%, 80%, 40%) and smiling (high, low) were manipulated. After subjects viewed one of 12 videotapes, they completed questionnaires rating therapist expertness, trustworthiness, attractiveness, masculinity and femininity. A comparison of the therapist with subjects' expectations of a therapist in general was obtained by pre- and post-testing utilizing a measure of client expectations. MANOVAs were performed on all ratings except expectation scores, where an ANCOVA was utilized. Main effects for therapist gender indicated the female therapist was rated as significantly more expert, attractive, trustworthy and feminine than the male (ps < .81). For ratings of masculinity, subject gender interacted with therapist gender (p < .001). Wain effects showed that high smiling was rated as more attractive and more feminine (ps < .01). Smiling and level of gaze interacted on …

An Exploratory Study of the Relationship Between Curiosity and Print Awareness of Four-Year-Old Children
This study has five chapters, organized in the following manner: (1) Chapter I contains the introduction, statement of the problem, purpose of the study, questions, significance of the study, and definition of terms; (2) Chapter II is a review of the literature; (3) Chapter III is a description of subjects and tests and procedures for treating the data; (4) Chapter IV contains the statistical technique of the analysis and the findings related to the questions, and (5) Chapter V consists of the summary, findings, conclusions, and recommendations. The problem of the study was to explore the relationship between curiosity and print awareness among four-year-old children. Subjects participating in the study were 71 four-year-old children from six licensed child care and preschool settings located in different geographical sections of a north central Texas city. The study included thirty-four girls and thirty-seven boys. Instruments used to collect the data were Kreitler, Zigler, and Kreitler's battery of curiosity tasks and Goodman's Signs of the Environment and Book Handling Knowledge tasks. Canonical I correlation analyses do not yield a significant relationship between variables of curiosity and print awareness. An alternate Pearson Product Moment correlation yielded some specific pairwise correlations between certain curiosity variables and …

Speech Recognition Using a Synthesized Codebook
Speech sounds generated by a simple waveform synthesizer were used to create a vector quantization codebook for use in speech recognition. Recognition was tested over the TI-20 isolated word data base using a conventional DTW matching algorithm. Input speech was band limited to 300 - 3300 Hz, then passed through the Scott Instruments Corp. Coretechs process, implemented on a VET3 speech terminal, to create the speech representation for matching. Synthesized sounds were processed in software by a VET3 signal processing emulation program. Emulation and recognition were performed on a DEC VAX 11/750. The experiments were organized in 2 series. A preliminary experiment, using no vector quantization, provided a baseline for comparison. The original codebook contained 109 vectors, all derived from 2 formant synthesized sounds. This codebook was decimated through the course of the first series of experiments, based on the number of times each vector was used in quantizing the training data for the previous experiment, in order to determine the smallest subset of vectors suitable for coding the speech data base. The second series of experiments altered several test conditions in order to evaluate the applicability of the minimal synthesized codebook to conventional codebook training. The baseline recognition rate …

The Manager as a Source of Departmental Power in a Manufacturing Company
The purpose of this study is to explore the relationship between position-related sources of power and person-related sources of power in organizations. The subject is the power of an organizational sub-unit compared to other units. Theory on the structural sources of power is well established in the literature. The question in this study is whether the individual manager, the person, is another major source of power for the organizational unit. A major objective of the study is to fill this gap in the literature on power in organizations. A secondary objective of this study is to see if one can rank the individual position-related sources of power and person-related sources of power, identified through a literature review, within each group in terms of their relative importance. The type of this study is exploratory. It is a descriptive study explaining the "what is" about the relationship between position and person sources of power in a manufacturing company. Results indicate that there is a two-way relationship between manager power and department power, and that one can rank order the sources of power in terms of their contribution to a department's or manager's power. Power is defined in this study as the ability …

The Relationship of Student Mathematics Scores on the Scholastic Aptitude Test to Teacher Effectiveness as Measured by the Texas Teacher Appraisal System
The purposes of this study were (1) to determine the scores on the quantitative portion of the SAT for 110 students and these students' math teachers' ratings on the TTAS, (2) to determine the nature of the relationship of the students' SAT scores to their teachers' TTAS ratings, and (3) to determine the nature of the relationship of the students' SAT scores to their sex. It was hypothesized that (1) there would be no significant relationship between a student's math score as measured by the quantitative portion of the SAT and the effectiveness of the student's math teacher as measured by the TTAS, and (2) there would be no significant relationship between a student's math score as measured by the quantitative portion of the SAT and the student's sex. The 110 subjects (60 males and 50 females) In this study took the quantitative portion of the SAT during the 1986-87 school year. This sample was drawn from a large suburban high school in the North Texas area. The effectiveness of the math teachers who taught the 110 students was measured by the Texas Teachers Appraisal System (TTAS). The statistical analyses indicated that (1) there was no significant relationship between a …

Influence of Significant Other and Locus of Control Dimensions on Women Entrepreneur Business Outcomes
The personality characteristic locus of control internality is widely-accepted as a trait possessed by women entrepreneurs. Recent research also suggests the presence of a coexisting attribute of similar strength, characterized as influence of a significant other. The presence of one personality characteristic implying perception of self-directed capability, together with indication of need for external assistance, poses a theoretical paradox. The study's purpose was to determine the nature and extent of direct and interactive effects which these and related variables had on entrepreneur return on investment. It was hypothesized that dimensions of significant other, as operationalized for this research, would support internality of locus of control and also modify constraining effects of educational and experiential disadvantage which the literature cites as pertinent to women entrepreneurs. This was nonexperimental, exploratory research of correlational cross-sectional design which examined hypothesized variable linkages. A convenience sample from a women's entrepreneur networking group was surveyed. Significant other elements were derived from factor analysis, resulting in four common dimensions. These factors, together with Rotter's Locus of Control instrument scores, reports on levels of education and experience, and hypothesized interactions, were independent variables. Hierarchial multiple regression was used to test a proposed path model. Two interpretable four-factor solutions …

A Study of the Relationships between Employee Stock Ownership Plans and Corporate Performance
This work collected four years of financial data from an employee-owned firm and a traditionally-owned firm from the same industry. The data were then organized to provide measures of three dimensions of corporate performance: (1) employee turnover, (2) productivity, and (3) profitability. Based upon a review of the literature, employee stock ownership plans (ESOP) are reported to enhance corporate performance after their adoption. Additionally, ESOPs are purported to perform better than traditionally-owned companies. This dissertation developed hypotheses to ascertain whether or not the particular ESOP used in this study conformed to these expectations. The first set of three hypotheses was tested using multiple regression techniques to determine if the ESOP experienced a reduction in turnover, an improvement in productivity, and an increase in profitability following its conversion to employee-ownership. The results of the regressions found that there was no incremental significance. There was no improvement noted in the performance of the ESOP firm. Another component of this investigation was to determine whether improvements in corporate performance were temporary or permanent phenomena. This portion of the research was rendered superfluous when no improvements were available for analysis. The final question that was examined was whether the ESOP would demonstrate better performance …

Effect of the New Criteria for Accreditation on Reaffirmation of Accreditation in the South
This study was concerned with characteristics of the process of reaffirmation of accreditation in the Southern region among institutions that completed reaffirmation under the revised _Criteria for Accreditation_ and those that completed reaffirmation under the former _Standards of the College Delegate Assembly._ The institutions that had completed reaffirmation under the new _Criteria_ were identified. A matching group of equivalent institutions which had last completed reaffirmation under the _Standards_ was created. Each group contained 66 institutions. Data were collected using the records of the Commission on Colleges of the Southern Association of Colleges and Schools. Four areas were identified in which the implementation of the _Criteria_ might affect the process of reaffirmation of accreditation: (a) institutional organization for the self-study, (b) visiting committee composition, (c) number of recommendations by visiting committees, and (d) substance of recommendations by visiting committees. A series of nine hypotheses were tested to assess these effects. The process of reaffirmation of accreditation does not appear to have been substantially affected by the implementation of the new _Criteria for Accreditation._ Institutional organization for the self-study appears unaffected by the implementation of the Criteria for most institutions. There appears, however, to be evidence that the _Criteria_ have effected change …

Transposition and the Transposed Modes in Late-Baroque France
The purpose of the study is the investigation of the topics of transposition and the transposed major and minor modes as discussed principally by selected French authors of the final twenty years of the seventeenth century and the first three decades of the eighteenth. The sources are relatively varied and include manuals for singers and instrumentalists, dictionaries, independent essays, and tracts which were published in scholarly journals; special emphasis is placed on the observation and attempted explanation of both irregular signatures and the signatures of the minor modes. The paper concerns the following areas: definitions and related concepts, methods for singers and Instrumentalists, and signatures for the tones which were identified by the authors. The topics are interdependent, for the signatures both effected transposition and indicated written-out transpositions. The late Baroque was characterized by much diversity with regard to definitions of the natural and transposed modes. At the close of the seventeenth century, two concurrent and yet diverse notions were in evidence: the most widespread associated "natural" with inclusion within the gamme; that is, the criterion for naturalness was total diatonic pitch content, as specified by the signature. When the scale was reduced from two columns to a single one, …

Group Counseling as an Intervention in Anger Expression and Depression in Older Adults
Depression is believed to be the most prevalent mental dysfunction among older adults, and depression and anger are frequently linked in theory and in therapy. This study was undertaken to determine whether participation in group counseling sessions would increase awareness and expression of anger and decrease depression levels in women aged 65 and older. Treatment group members were compared to a matching control group. Both groups completed the Anger Self Report Questionnaire and the Beck Depression Inventory. Comparison of the ASR subscale scores, Awareness of Anger, Expression of Anger, Guilt, Condemnation of Anger, and Mistrust, revealed no significant differences between the treatment and control groups. However, the treatment group scored significantly higher on the BDI than did the control group. Analysis of variance of the ASR and the BDI, and the variables upon which the treatment and control groups were matched revealed some significant differences, and comparison of the women in this study with the two groups upon whom the ASR was validated showed this study's older women scored significantly lower than the validation groups on the ASR. The author concluded that six sessions is not long enough to effect change in either anger awareness or expression in older women, …

The Effects of Cognitive Style and Socialization Background on Patterns of Behavior: Integrating Individual Differences (Using the MBTI) with Meadian Socialization Theory
The general purpose of this study is to examine the effects of socialization background and cognitive style on individuals' patterns of behavior. The more specific purpose is to integrate the individual differences factor using the Myers-Briggs Type Indicator with Meadian Theory of Socialization in order to explore the ways in which a group of incarcerated individuals with prior felony and misdemeanor convictions and a group of college students are different regarding their different socialization background and cognitive styles. Data for this study were collected from a university and a county jail in Texas. During the process of data collection, two questionnaires consisting of 117 items were used to measure individual characteristics and elements of socialization background. This study is organized into four different chapters. Chapter I involves a detailed review of related literature, the purpose of the study, stated hypotheses, significance of the study, and limitations. Chapter II discusses methodological procedures and Chapter III presents the findings of the study. The last chapter includes a detailed conclusion and practical implications of the study. The findings in this study indicated that the group of incarcerated individuals and the group of college students are significantly different in terms of their different individual …

A Path Analysis of a Job Burnout Model Among Firefighers
The purpose of this study was to propose an exploratory causal model that examines the influence of several antecedent variables on burnout. The antecedent variables included age, marital status, education, tenure, Type A personality, Jungian types, death anxiety, leadership style, job satisfaction, stress, coping efficacy, and marital satisfaction. The validity of the causal model was tested by using path analysis. Subjects were 100 male firefighters who completed self-report measures of the predictor variables. Instruments included the Jenkins Activity Survey, Myers- Briggs Type Indicator, Collett-Lester Attitudes Toward Death Scale, Leader Behavior Description Questionnaire, Job Descriptive Index, Perceived Job Stress, The Coping Inventory, Dyadic Adjustment Scale, and the Maslach Burnout Inventory. Perceived work stress made the only direct contribution to the variance in burnout. Direct paths were found to stress from job satisfaction, Type A personality, and single marital status. Job satisfaction was directly related to leadership (consideration) and the Jungian Introversion, Feeling, and Perceiving preferences. Direct paths were found to marital satisfaction from death anxiety, leadership (consideration), and leadership (structure). Leadership (consideration) was directly related to structure. From the above results, it can be concluded that perception of stress is an important factor in predicting burnout. Other factors are important contributors …

Purchasing Power Parity and the Efficient Markets: the Recent Empirical Evidence
The purpose of the study is to empirically determine the relevance of PPP theory under the traditional arbitrage and the efficient markets (EPPP) frameworks during the recent floating period of the 1980s. Monthly data was collected for fifteen industrial nations from January 1980 to December 1986. The models tested included the short-run PPP, the long-run PPP, the EPPP, the EPPP with deviations from expectations, the forward rates as unbiased estimators of future spot rates, the EPPP and the forward rates, and the EPPP with forward rates and lagged values. A generalized regression method called Seemingly Unrelated Regression (SUR) was employed to test the models. The results support the efficient markets approach to PPP but fail to support the traditional PPP in both the short term and the long term. Moreover, the forward rates are poor and biased predictors of the future spot rates. The random walk hypothesis is generally supported.

Life Histories Behavior and Space Partitioning in Selected Species of Western North American Plecoptera
Five species of stoneflies (Zapada haysi, Plumiperla diversa, Taenionema pacificum, Isoperla petersoni, Arcynopteryx compacta) from the North Slope and Interior of Alaska were examined for seasonal patterns of emergence of adults and growth of nymphs. Generally growth was retarded during the winter in this region, and all species except I. petersoni completed growth prior to January. The life cycles of six stonefly species (Prostoia besametsa, Triznaka signata, Sweltsa coloradensis. Isoperla fulva, Skwala parallela, Claassenia sabulosa) are described from northern New Mexico. In this region growth was generally less retarded during the winter than in Alaska; P. besametsa completed all nymphal growth during late fall and winter. Drumming behavior of a Colorado population of Pteronarcella badia was described using an evolutionary framework to explain the maintenance of signal variation in this species. Laboratory experiments were used to explore the effect of intraspecific and interspecific interactions on spatial partitioning in P. badia and Claassenia sabulosa. P. badia exhibited clumping and distributed itself as the surface area of substrate in low densities; however, in the presence of C. sabulosa its distribution was random and different from available surface area. A field study was used to examine spatial partitioning by three New Mexico stonefly …

An Empirical Investigation of the Lobbying Influence of Large Corporations on Selected FASB Standards
The Financial Accounting Standards Board is a private sector rule making body. Congressional inquiries have questioned whether the setting of accountin standards should remain in the private sector. Congressional critics have charged that the FASB has been captured by special interests and recommended that a governmental agency assume responsibility for standard setting. Specifically, critics charge that large corporations capture the Big Eight accounting firms who, in turn, have captured the FASB. Previous capture studies have concluded that the standard setting process is pluralistic and that the FASB has not been captured. The studies have focused on the influence of the Big Eight to determine if the FASB has been captured. They assume if standards do not reflect the expressed preferences of the Big Eight, then Congressional criticisms are invalid. The studies also assume a unidirectional influence between participants in the process and have ignored the intensity of preferences of the respondents.The purpose of this study is to provide a theoretical framework to specify selection of standards that would be expected to be subject to capture. This framework also recognizes the duo-directional nature of influence. The allegations of capture were tested using the standards selected in accordance with the theoretical framework. …

A Follow-Up Study of Autistic and Autistic-Like Children
Autism is a lifelong handicapping disorder that occurs on a continuum of severity. Children who show mild autistic behaviors but do not meet the criteria for a diagnosis of autism are often called autistic-like, but it is not known if their development and functioning are similar to that of autistic children. A follow-up study was done on 35 autistic and autistic-like children who were an average of 3 years of age when initially seen. Initial test scores indicated that the children were similar on measures of intellectual/developmental functioning, receptive vocabulary, and adaptive functioning. Approximately 4 years later they were evaluated again. Using the Childhood Autism Rating Scale, the children were divided at follow-up into three groups: nonautistic, mildly/moderately autistic, and severely autistic. Most children made gains on intelligence tests and displayed a diminishing number of autistic symptoms. Changes in nonverbal intelligence, adaptive functioning and receptive vocabulary scores depended on group membership. The results are discussed in relation to the reported stability of cognitive functioning in young autistic children and the implications for clinical practice, early intervention, and research on attachment. The nature of the syndrome of autism is also discussed, particularly in its relation to the milder, atypical children. The …

Professional Commitment, Organizational Commitment, and Organizational-Professional Conflict in the Internal Audit Function Model: Development and Test
This dissertation is a descriptive, exploratory examination of professional commitment, organizational commitment, and conflict between those commitments in the internal audit profession. That conflict has been suggested in prior studies as the source of dysfunctional outcomes such as increased role stress, high turnover, decreased job satisfaction, and the exercise of improper judgment leading to audit failures. The descriptive aspect of this study deals with the development of a more comprehensive structural model of the factors and relationships involved in commitment and conflict than has been developed by previous research dealing with accountants. The exploratory aspect deals with the testing and refinement of the developed model utilizing the internal audit profession as the field of examination. The model developed in this study is derived from the synthesis of factors suggested by role theory, the concept of side bets, the cosmopolitan-local construct, and the concept of commitment as a process. This research utilizes a questionnaire administered to 205 practicing internal auditors in order to test 30 hypothesized relationships. Path analysis is used to determine the significant direct relationships between variables with a process of theory trimming being conducted in order to produce more parsimonious structural models. Indirect relationships between significant variables are …

Analysis of Acid Gas Emissions in the Combustion of the Binder Enhanced d-RDF by Ion Chromatography
Waste-to-energy has become an attractive alternative to landfills. One concern in this development is the release of pollutants in the combustion process. The binder enhanced d-RDF pellets satisfy the requirements of environmental acceptance, chemical/biological stability, and being storeable. The acid gas emissions of combusting d-RDF pellets with sulfur-rich coal were analyzed by ion chromatography and decreased when d-RDF pellets were utilized. The results imply the possibility of using d-RDF pellets to substitute for sulfur-rich coal as fuel, and also substantiate the effectiveness of a binder, calcium hydroxide, in decreasing emissions of SOx. In order to perform the analysis of the combustion sample, sampling and sample pretreatment methods prior to the IC analysis and the first derivative detection mode in IC are investigated as well. At least two trapping reagents are necessary for collecting acid gases: one for hydrogen halides, and the other for NOx and SOx. Factors affecting the absorption of acid gases are studied, and the strength of an oxidizing agent is the main factor affecting the collection of NOx and SOx. The absorption preference series of acid gases are determined and the absorption models of acid gases in trapping reagents are derived from the analytical results. To prevent …

The American University of Beirut and Its Educational Activities in Lebanon, 1920-1967
The purpose of this study was to trace the historical development of the American University of Beirut and its educational contributions in Lebanon and the Middle East from 1920 to 1967. Through their activities in the Levant in the early nineteenth century, the American missionaries virtually laid the foundations of the Syrian Protestant College, later known as the American University of Beirut. Though religion was the cornerstone in the founding of the University, under the pressure of the local environment, its secular character was to be substituted for the religious one. The establishment of the University in 1866 marked the beginning of the system of higher education in the Arab world. As the first established institution of higher learning, the University played a significant role in raising the level of literacy throughout the region. Despite the difficult times that the University faced throughout its history, it survived and continued its dedicated mission to serve the people of Lebanon and the entire area. For the University, the first 50 years under Ottoman rule was a period of surviving and maintaining its existence. With the freedom it came to enjoy during the French Mandate and later during independence, the University moved into …
