Perceptions of Administrators and Faculty Members of a Faculty Development Plan

Perceptions of Administrators and Faculty Members of a Faculty Development Plan

Date: May 1990
Creator: Tawasay, Prasit
Description: This study was a comparison of the perceptions of administrators and faculty members regarding the actual and expected role of selected components of a faculty development plan at Srinakharinwirot University-Phitsanulok, Thailand. The study also investigated whether the demographic classifications of administrators and faculty members were related to their perceptions regarding the actual and expected role of selected components of a faculty development plan. Forty-one administrators and sixty full-time faculty members completed the survey instrument. Statistical tests used to summarize and analyze the data included mean, standard deviation, t test, chi-square, and correlation ratio. The results and findings of this study showed that (a) there were no major differences between administrators and faculty members related to their perceptions of a faculty development plan; (b) faculty members perceptions of the actual and expected role of selected components of a faculty development plan were consistent to a greater degree than were the perceptions of administrators; (c) significant differences between the perceptions of administrators regarding the actual and expected role of selected components of a faculty development plan were found for only one item: study leaves; (d) there were significant differences between the perceptions of administrators and faculty members regarding the actual role of ...

Effect of Modern Training Techniques on Economically-Disadvantaged Homeless People

Effect of Modern Training Techniques on Economically-Disadvantaged Homeless People

Date: August 1990
Creator: Frankenberger, John J. (John Joseph)
Description: This study examined a segment of the homeless population who participated in a jobs training program. The research investigated the effect of socioeconomic status, self-esteem, and locus of control on the clients in getting and keeping jobs. The training was a comprehensive 36-day treatment dealing with three major areas: (a) how to get a job, (b) how to keep a job, and (c) how to develop life-coping skills. A quasi-experimental research design was used for testing by t-tests, two-by-two repeated-measured anova, chi-square tests, and regression analysis. The findings showed that high socioeconomic status clients demonstrated higher self-esteem and internal locus of control than low socioeconomic status clients at the start of the treatment. The treatment had a significant effect on both groups with an increase in self-esteem and internal locus of control and a decrease in both external locus of control dimensions of powerful others and chance. The treatment had a greater effect on the low socioeconomic status clients than on the high socioeconomic status clients on increases in self-esteem and locus of control—internal. Both groups were successful in finding jobs, with 79% for high socioeconomic status clients and 74% for low socioeconomic status clients having jobs at the end ...

Personality Characteristics Associated with Pet Ownership: Validating the Theoretical Propositions of Boris Levinson

Personality Characteristics Associated with Pet Ownership: Validating the Theoretical Propositions of Boris Levinson

Date: August 1990
Creator: Esparza, Jana Scoville
Description: The purpose of the present study was to provide validation for Levinson's theory about pets and human personality development. Levinson (1978) proposed that the personality development of individuals who have pets to which they are attached differs from that of those who do not have pets and that pets play an important role in facilitating the development of certain adaptive personality traits. In the present study, specific areas that were addressed included differences in certain personality characteristics between life-long pet owners who were strongly attached to their pets, life-long pet owners who were less strongly attached to their pets, and people who had owned pets for only a limited period of time in their lives. One hundred undergraduates completed the Pet Attitude Scale, the Tennessee Self Concept Scale, the Personality Research Form - Form E, the Hogan Empathy Scale, the Fundamental Interpersonal Relations Orientation - Behavior (FIRO-B), and the IPAT Anxiety Scale Questionnaire. No significant differences were found between the three pet owner groups in levels of affiliation with other people, impulse control, nurturance, succorance, capacity for empathy, and anxiety levels. In addition, no significant differences were found between the three pet owner groups in interpersonal behavior characteristics or self-esteem. ...

An Investigation of Selected Female Singing- and Speaking-Voice Characteristics Through Comparison of a Group of Pre-Menarcheal Girls to a Group of Post-Menarcheal Girls

An Investigation of Selected Female Singing- and Speaking-Voice Characteristics Through Comparison of a Group of Pre-Menarcheal Girls to a Group of Post-Menarcheal Girls

Date: May 1990
Creator: Williams, Bonnie Blu
Description: The purpose of this study was to compare the speaking fundamental frequency, physiological vocal range, singing voice quality, and self-perceptions of the singing and speaking voice between two groups of girls ages 11 through 15 years, who were pre-menarcheal by 6 months and post-menarcheal by 10 months or more. Subjects were volunteers who attended a North Texas public school system. Each subject was examined by an otolaryngologist. Age, height, weight, a hearing screening, and information on music classes and/or private music lessons were obtained. The speaking fundamental frequency measure was obtained by having each subject speak for 30 seconds on a subject of choice and read a passage of approximately 100 syllables. The vocal range measure was obtained by having each subject begin at an arbitrary pitch and sing mah and moo up the scale as high as possible and mah and moo down the scale as low as possible. These four measures were repeated with the researcher giving visual gestures. For singing-voice quality, each subject sang "America" in the key of her choice and again in the key of F major. Each subjects singing voice was rated according to breathiness. Data regarding self-perceptions of the singing and speaking voice ...

Parental Cultural Mistrust, Background Variables, and Attitudes Toward Seeking Mental Health Services for Their Children

Parental Cultural Mistrust, Background Variables, and Attitudes Toward Seeking Mental Health Services for Their Children

Date: August 1990
Creator: Ahluwalia, Ekta
Description: Attitudes toward mental illness and the willingness to seek psychological treatment for their children among ethnic minority group parents were investigated. Participants consisted of black, Hispanic, Native American and Asian parents. All parents were given the Terrell and Terrell Cultural Mistrust Inventory, Cohen and Struening Opinions About Mental Illness Scale, Reid-Gundlach Social Services Satisfaction Scale, Fischer-Turner Attitudes Toward Seeking Professional Help Scale, and Ahluwalia Parents' Psychological Help-Seeking Inventory. A multiple regression model was used to explore the purpose of this study. Parental mistrust level, ethnicity, education, income level, and opinions about mental illness served as predictor variables. The criterion variables consisted of scores on the Social Services Satisfaction Scale and Attitudes Toward Seeking Professional Psychological Help Scale. The results indicated that the most significant predictor of psychological help-seeking was parental cultural mistrust level. Parents with higher cultural mistrust levels were less likely to seek help. Education was also predictive of black and Native American parents' help-seeking attitude and willingness to seek psychological help for their children. Black and Native Americans with lower levels of education were less willing to seek treatment for their children than members of those ethnic groups with higher levels of education. Ethnicity was also related to ...

Agenda-Setting by Minority Political Groups: A Case Study of American Indian Tribes

Agenda-Setting by Minority Political Groups: A Case Study of American Indian Tribes

Date: May 1990
Creator: McCoy, Leila M. (Leila Melanie)
Description: This study tested theoretical propositions concerning agenda-setting by minority political groups in the United States to see if they had the scope to be applicable to American Indian tribes or if there were alternative explanations for how this group places its agenda items on the formal agenda and resolves them. Indian tribes were chosen as the case study because they are of significantly different legal and political status than other minority groups upon which much of the previous research has been done. The study showed that many of the theoretical propositions regarding agenda-setting by minority groups were explanatory for agenda-setting by Indian tribes. The analyses seemed to demonstrate that Indian tribes use a closed policy subsystem to place tribal agenda items on the formal agenda. The analyses demonstrated that most tribal agenda items resolved by Congress involve no major policy changes but rather incremental changes in existing policies. The analyses also demonstrated that most federal court decisions involving Indian tribes have no broad impact or significance to all Indian tribes. The analyses showed that both Congress and the federal courts significantly influence the tribal agenda but the relationship between the courts and Congress in agenda-setting in this area of policy ...

The Prediction of Industrial Bond Rating Changes: a Multiple Discriminant Model Versus a Statistical Decomposition Model

The Prediction of Industrial Bond Rating Changes: a Multiple Discriminant Model Versus a Statistical Decomposition Model

Date: December 1985
Creator: Metawe, Saad Abdel-Hamid
Description: The purpose of this study is to investigate the usefulness of statistical decomposition measures in the prediction of industrial bond rating changes. Further, the predictive ability of decomposition measures is compared with multiple discriminant analysis on the same sample. The problem of this study is twofold. It stems in general from the statistical problems associated with current techniques employed in the study of bond ratings and in particular from the lack of attention to the study of bond rating changes. Two main hypotheses are tested in this study. The first is that bond rating changes can be predicted through the use of financial statement data. The second is that decomposition analysis can achieve the same performance as multiple discriminant analysis in duplicating and predicting industrial bond rating changes. To explain and predict industrial bond rating changes, statistical decomposition measures were computed for each company in the sample. Based on these decomposition measures, the two types of analyses performed were (a) a univariate analysis where each decomposition measure was compared with an industry average decomposition measure, and (b) a multivariate analysis where decomposition measures were used as independent variables in a probability linear model. In addition to statistical decomposition analysis, multiple ...

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

Date: May 1990
Creator: Nagel, Jeffrey A.
Description: The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one ...

The Influence of the First Amendment on Academic Freedom

The Influence of the First Amendment on Academic Freedom

Date: May 1990
Creator: Ferdon, Douglas Robert, 1945-
Description: Academic freedom has gone through three distinct eras yet each era overlaps a great deal with the one following it. The first era was the bureaucratic. It was exemplified by the negotiations between administrators and professors in the 1920s. The American Association of University Professors and the American Association of Colleges began cooperating and a hierarchical structure emerged, with the tenured professor at the top of the faculty. The second era was the political era and it was mainly a result of loyalty oaths, which began after the first World War and then escalated again during the 1930s when communism became a major concern. The political era then gave way to the legal era when the first academic freedom cases went to the United States Supreme Court in the 1950s. The first cases were the result of political pressures that became legal pressures. Most of the early court cases were based on communism. The legal era has produced changes. There are now more rights; for students and teachers of all levels, including pre-college levels, are guaranteed some academic freedom rights. However, the First Amendment and academic freedom are not synonymous because a professor usually cannot win a case based solely ...

Toxicity of Chromium and Fluoranthene From Aqueous and Sediment Sources to Selected Freshwater Fish

Toxicity of Chromium and Fluoranthene From Aqueous and Sediment Sources to Selected Freshwater Fish

Date: May 1990
Creator: Gendusa, Tony C.
Description: Research efforts in aquatic toxicology have historically centered on the chemical analyses and toxic effects of waters to aquatic organisms. More recently, sediment-source toxicity has been explored, with efforts concentrated on establishing sensitive and accurate methodologies. This study focused on the toxicity of trivalent chromium, hexavalent chromium, and fluoranthene to Pimephales promelas, Ictalurus punctatus, and Lepomis macrochirus. Test fish were exposed to both water-borne and sediment-source toxicants for 96 hours (h) and 30 days (d). A 96-h and 30-d LC50 (mg/L Cr, ug/L Fluoranthene) was determined for each fish species exposed to aqueous toxicants. In addition, 96-h and 30-d LC50s were determined for each fish species from sediment chromium concentrations (mg/kg) and sediment fluoranthene concentrations (ug/kg). Although lethality endpoints were used throughout this research, acute effects other than mortality were determined for Lepomis macrochirus exposed to hexavalent chromium. Lethal toxicity values (96-h and 30-d LC50 and their 95% confidence limits) for trivalent chromium could not be determined since trivalent chromium concentations above 6.0 mg/L could not be obtained at water pHs compatible with these fish species. Trivalent chromium addition to test waters at pHs compatible with fish survival resulted in a chromium precipitate that was not lethal to test fish. ...

A Cost-Benefit Analysis of the Implementation of Texas House Bill 72 in Selected Texas Public School Districts

Date: May 1990
Creator: Bradford, Ronald W. (Ronald Wayne)
Description: This study was conducted to analyze the effect of implementation of Texas House Bill 72 on budgets of selected Texas public school districts and to ascertain educational benefits to students derived from implementation of the bill as perceived by superintendents. Questionnaires were sent to superintendents of the Region 10 Education Service Center to determine perceived educational benefits to students. A demographic data sheet provided information for classifying respondents by educational experience, superintendent experience, and district enrollment classifications. Sixty-two districts responded. Official public school budget data for each district were analyzed for fiscal years 1983 through 1986 as were data from the questionnaire. Overall statistical information was gleaned through CONDESCRIPTIVE. Mean total expenditures, mean total tax rate, and state fiscal aid data were compiled, tabulated, and reported for each enrollment classification and entire sample. In addition, a t-test between the difference of two independent means at a probability level of .05 was applied. The two independent means were the averages of data for the two years prior to and after implementation of the law for expenditures, tax rates, and state fiscal contributions. Data comparing local and state expenditures were compiled, tabulated, and reported for each group to compare local and state ...

A Model for Predicting Bereavement Outcome in Widowhood

A Model for Predicting Bereavement Outcome in Widowhood

Date: May 1990
Creator: Allen, Susan Elise
Description: The present longitudinal study examined the effects and interactions of several variables thought to affect adjustment to conjugal bereavement. Questionnaires were administered to 147 conjugally bereaved subjects and to 46 persons bereaved of close relatives other than spouse. Independent variables included experienced competence (self-esteem, locus of control, coping self-efficacy, and prior coping strategies), impact of loss (anticipation and preventabillty of loss, centrality of relationship and life change), and perceived resources. All of the independent variables were found to be important predictors of adjustment in conjugal bereavement. However, hypothesized interactions among variables were generally not found. Experimental variables were better predictors of adjustment in conjugal bereavement than were demographic variables. Contrary to prediction, widowed subjects tended to become more lonely and showed increased bereavement adjustment difficulties over a six month period of time. However, post hoc analysis suggested that levels of adjustment do not decline over the long term in widowhood. The present study supports a view of widowhood as a multidimensional event, characterized by seemingly contradictory feelings, experiences, and behaviors.

The Development and Interpretation of Several Symbolic Models of Thought

The Development and Interpretation of Several Symbolic Models of Thought

Date: May 1986
Creator: Keyton, Michael M. (Michael Murray)
Description: Philosophical and physiological investigations define thought to be the result of thinking. psychological Inquiry has mainly focused on discovery of the mechanisms and topology of thought. Philosophical Inquiry either has explored the mind-body problem or has analyzed the linguistics of the expression of a thought. However, neither has Investigated adequately phenomenal characteristics of thought Itself, the Intermediary between the production and the expression of a thought. The use of thought to analyze phenomenal characteristics of thought engenders a paradox. If the expression of thought requires finite series of linked words with rules governing syntax, then analysis of both the thought and the expression of the thought must necessarily transcend the linguistic level. During the last century many examples of logical paradoxes In linguistics of thought have been given. The culminating difficulty of dealing with a finite structure, a characteristic of any language, Is Godel's Incompleteness Theorem, which says in essence that in order to render all decisions about a finite system requires the use of material outside the system. Thus, a potentially complete interpretation of thought must use some technique which is basically non-linguistic . Wittgenstein proposed such a method with his "Picture theory. " This technique solves the major ...

A Comparative Study of Internal and External Auditors' Judgment of Internal Auditor Independence

A Comparative Study of Internal and External Auditors' Judgment of Internal Auditor Independence

Date: May 1986
Creator: Pei, Ker-Wei
Description: The purpose of this study is to provide empirical evidence relevant to perceptions of internal auditor independence. Specifically, this study investigates how the auditor practitioners (both internal and external auditors) perceive the importance of five selected factors that characterize the organizational settings of an internal audit department. Role theory is the frame of reference used to develop the conceptual model for this study in which the judgment of internal auditor independence is viewed as the role perception of internal auditors. A modified version of the Brunswik's lens model was developed to provide "paramorphic" representation of judgment of independence. The research methodology of this study is based upon a laboratory experiment in which a replicated factorial design was used to elicit the subjects' judgments of independence. The data collected from this experiment were analyzed by three statistical methods: conjoint measurement, multiple regression, and cluster analysis. The major findings follow. First, the five selected factors were not perceived as equally important by the subjects. In general, internal auditor's scope of audit. scope o^ service, and reporting level were perceived as more important than adequacy of organizational support. and formalization of audit policies. Second, the two groups of auditors disagree, significantly, on the ...

The Genetics of Pigmentation in Corynebacterium poinsettiae ATCC 9682

Date: August 1986
Creator: Campbell, Alan L. (Alan Lee)
Description: Corynebacterium poinsettiae mutant strains blocked in carotenoid biosynthesis were obtained by treatment with the mutagen N-methyl-N1-nitro-N-nitrosoguanidine. Additional carotenoid (Crt) mutant strains were obtained from a previous study conducted in our laboratory. Fifty-nine Crt mutants affected in carotenoid biosynthesis were examined by a normal phase high performance liquid chromatography (HPLC) system. Pigment extracts of Crt mutants and C. poinsettiae wild type strains were resolved by an isocratic system with hexane:acetone:dicholoromethane, 11.35:1.73:1.00 (by vol.) as the eluting solvent. In addition to the five major peaks, twelve minor peaks were observed in the wild type C. poinsettiae strain used in this study. Crt mutant and wild type strain peak heights were measured from the individual chromatograms and the peak height data set created was analyzed using the Statistical Analysis System program to perform a cluster analysis. The cluster analysis revealed five carotenoid mutant groups. Carotenoid pigments which accumulated or were absent in each of the cluster groups are reported. Cluster group 1 mutants (CrtA) are blocked in the dehydrogenase(s) which is(are) responsible for the dehydrogenations between phytoene and lycopene. Cluster group 2 mutants (CrtB) appear to be blocked at a second dehydrogenase specific for the dehydrogenation from C.p. 470 to C.p. 496. Cluster ...

Relationship of Sex Role Orientation to Preference for Type of Response in Counseling

Relationship of Sex Role Orientation to Preference for Type of Response in Counseling

Date: May 1985
Creator: Workman, William J. (William John)
Description: This study compared beginning and advanced counselor education students on self-reported sex-role orientation and preference for selected counseling responses. It was assumed that sex-role socialization leads to restrictive attitudes that make it difficult for students to acquire and use selected interpersonal counseling skills. It was anticipated that counselor education training programs would provide a means for students to overcome the limitations imposed by sex-role socialization practices. Subjects in this study were 87 counselor education graduate students, 34 advanced students enrolled in the final two courses required for the master's degree and 53 beginning students enrolled in the first course in the master's degree sequence. Based on scores obtained from the Bern Sex-Role Inventory, subjects were divided into three groups: (1) feminine, (2) androgynous, (3) masculine. The Response Alternatives Questionnaire was used to determine subjects' preference for counseling responses.

A Quasi-Experimental Study of Behavior in the Professional Negotiation Process: An Analysis of the Nigerian Setting

Date: August 1986
Creator: Akiri, Agharuwhe Anthony, 1950-
Description: The problem investigated by this study was that of understanding types of behaviors exhibited by participants in negotiations processes and impact of behaviors on collective bargaining in Nigeria. The study's three purposes were to describe the nature and extent of interpersonal conflict that occurs in collective bargaining, to determine the consequences that stem from such conflict, and to suggest the behaviors and performances during the face-to-face negotiations that should exist to enhance labor-management relations in Nigerian public education. This study examined behavior in negotiations by using simulation, i.e., a quasiexperimental method. Four outcomes of negotiations--time required to reach agreement, terms of agreements, verbal behavior exhibited during negotiations, and satisfaction derived by negotiators in negotiations—were examined.

Chromatographic and Spectroscopic Studies on Aquatic Fulvic Acid

Chromatographic and Spectroscopic Studies on Aquatic Fulvic Acid

Date: August 1986
Creator: Chang, David Juan-Yuan
Description: High Performance Liquid Chromatography (HPLC) was used to investigate the utility of this technique for the analytical and preparative separation of components of aquatic fulvic acids (FA). Three modes of HPLC namely adsorption, anion exchange and reversed phase were evaluated. Aquatic fulvic acids were either extracted from surface water and sediment samples collected from the Southwest of the U.S., or were provided in a high purity form from the USGS. On the adsorption mode, a major fraction of aquatic fulvic acid was isolated on a semipreparative scale and subjected to Carbon-13 NMR and FAB Mass Spectroscopy. Results indicated that (1) The analyzed fraction of fulvic acid contains more aliphatic than aromatic moieties; (2) Methoxy, carboxylic acids, and esters are well-defined moieties of the macromolecule; (3) Phenolic components of the macromolecules were not detected in the Carbon-13 NMR spectrum possibly because of the presence of stable free radicals. Results of the anion exchange mode have shown that at least three types of acidic functionalities in aquatic fulvic acid can be separated. Results also indicated that aquatic fulvic acid can be progressively fractionated by using subsequent modes of HPLC. Results of reversed phase mode have shown that (1) The fractionation of aquatic ...

Methods Development for Ion Chromatography

Methods Development for Ion Chromatography

Date: May 1986
Creator: Supachai Maketon
Description: Ion chromatography (IC) as developed by Small et. al. in 1975 has become an efficient and reliable analytical technique for simultaneous analysis of multiple ions in solution. The principle requirement prior to use the IC for an analysis is sample preparation; these include sample decomposition, solvent extraction, and trapping in case the target element is in the gas phase, etc. Solvent extractions for fluoride, chloride, sodium, ammonium, and potassium ions which are soluble in soils are described. Sample decompositions include silicate rocks using hydrofluoric acid for the determination of phosphorus; organic pesticides using lithium fusion technique for the determination of halide and cyanide ions are also described. After these sample preparation techniques, the aqueous solutions obtained were analyzed on the ion chromatograph for the analyses of the anions and cations mentioned above. Recovery and reproducibility of each technique is in general quite good and the comparison between the results obtained from the IC method and other instrumentation are given.
