The Effects of Lateralization of Task on the Use of the Dual Task Paradigm as a Measure of General Intelligence

Description: Stankov's work on attention and intelligence suggests that the dual task paradigm, requiring the division of attention, is a better measure of general intellectual ability than the single task paradigm which does not make this demand. Sixty right handed undergraduates remembered digit and visual-spatial sequences alone and in two dual task conditions involving lateralized key tapping as the primary task. R gher intercorrelations were found under dual task conditions in which the tasks competed for the same hemisphere's resources. Better memory performance resulted when both tasks were lateralized to the same hemisphere. Hierarchical models combining general attention resources with ,lateralized hemispheric resources best account for these resutsi

The Effects of Oat Fiber and Corn Bran on Blood Serum Cholesterol and Triglyceride Levels

Description: Forty Sprague Dawley rats were randomly placed in five groups with eight rats per group. Each group varied in dietary composition for fiber type and carbohydrate source. Groups one and two received oat fiber and either sucrose or corn starch as the carbohydrate source. Groups three and four received corn bran as the fiber source and either sucrose or corn starch as the carbohydrate source. Group five (considered the control group), received Purina standard rat chow. Analysis of variance showed only significant differences for food intake, and the control group had a significantly higher food intake. Weight gain, serum cholesterol and triglyceride levels showed no significant differences.

The Effects of Participation in a Buddy System on the Self-Concept, Academic Achievement, Attrition Rate, and Congruence Level of Community College Developmental Studies Students

Description: This dissertation sought to determine the effects of a buddy system on a student's self-concept, academic achievement, attrition rate, and congruence levels. The buddy system treatment randomly paired two students for the purposes of sharing ideas, working on assignments, getting to know each other, and supporting one another. The study included three randomly selected sections of pre-college level, developmental writing classes from the Brookhaven College of the Dallas County Community College District. Three other classes served as the control group, and one instructor taught all six sections of the course. Three instruments were used as measures of change: the Tennessee Self-Concept Scale (TSCS), designed by William H. Fitts, measured self-concept levels; the Personality and Educational Environment Scale (PEES), created by Roger Boshier, measured congruence levels; and a written paragraph measured achievement levels in English. Attrition percentages were based on the number of students enrolled during the second week of class who were not present during the sixteenth week of class. To test for significance, an analysis of covariance procedure was used on the TSCS, PEES, and written paragraph results, and a test for the difference between proportions for independent groups was used on the attrition percentages. The class sections were nested under either the experimental or the control group to identify significant differences between class sections. On the TSCS, a significance of .96 among sections and .48 between groups indicated no significant change had occurred in self-concept levels. For the PEES, a significance of .30 among sections and .75 between groups indicated no change had occurred in congruence levels. Finally, on the paragraph assessment, a significance of .87 among sections and .31 between groups showed no change had occurred in achievement levels. However, the test for significance of the difference between attrition percentages revealed that the buddy system treatment was ...

Effects of Water Source, Suspended Solids, and Acclimation on Biotransformation of 2 /4-Dichlorophenoxy Acetic Acid in Aquatic Systems

Description: In recent years there has been a great deal of scientific interest in processes that affect the fate of organic chemicals in the environment. one main reason for this increased interest is due to greater environmental concern over accidental or purposeful release of these chemicals into the environment by man. A major environmental concern is the increased use of pesticides over the last few years. In the thirty years prior to 1978 the use of pesticides has increased by a factor of forty (Ridgeway et al., 1978). Recently the use of herbicides has been increasing, but that of insecticides has stabilized (Willis, 1983). Detectable amounts of organic pesticides can be found in many areas of the biosphere. For toxic organic chemicals to be used safely, researchers must have a clear understanding of the fate and persistence of these chemicals when they are released into the environment. This understanding will also allow the development of new products that, when properly used, will not produce adverse effects to man or the environment (Weber, 1972). According to the Toxic Substance Control Act (TSCA) any new or expanded-use chemical that might be released into the environment must be tested for environmental hazard.

Emergence, Growth, Drift and Microdistribution of Stoneflies (Plecoptera) in an Ozark Foothills Stream, Delaware County

Description: Adult stonefly emergence, nymphal growth, drift and microdistribution were examined in Battle Branch, a secondorder, spring-fed stream, from November, 1982 to May, 1984. Adults of 22 species emerged successionally, with specific adults present every month. Searching emergent objects and the stream margin was best for collection of winter and early spring emerging species. Sweeping the streamside and light trapping were most efficient for late spring and summer emerging species. Nymphal growth for nine abundant species generally fit double log or semilog models. Drift was low, but did show a post-sunset pulse. Generally, leaf material was found to be significantly related (p<O.001) to density, diversity and biomass of stoneflies in Battle Branch.

An Empirical Investigation of the Complementary Value of a Statement of Cash Flows in a Set of Published Financial Statements

Description: This research investigates the complementary value of a statement of cash flows (SCF) in a set of published financial statements. Selected accounting studies and selected parts of communication theory are used to argue the case for treating an SCF as a primary financial statement. Ideas adapted from communication theory are also used to decide key issues involved in developing an SCF. Specifically, the study selects a direct rather than a reconciling format for an SCF; it also defines cash to include currency, bank accounts, and marketable securities and exclude claims to cash such as notes and accounts receivable. The definition of cash limits cash flow to strict receipts and disbursements; it excludes constructive receipts and disbursements.

An Empirical Investigation of the Discriminant and Predictive Ability of the SFAS No. 69 Signals for Business Failure in the Oil and Gas Industry

Description: In 1982, the Financial Accounting Board (FASB) issued Statment of Financial Accounting Standards No. 69 (SFAS No. 69) which required oil and gas producing companies to disclose supplementary information to the basic financial statements. These disclosures include, costs incurred, capitalized costs, reserve quantities, and a standardized measure of discounted cash flows. The FASB considered these disclosures to be necessary to compensate for the deficiencies in historical cost financial statements. The usefulness of the new signals created by SFAS No. 69, however, is an empirical question and research regarding that objective is lacking. The objective of the study is to test the usefulness of SFAS No. 69. The research strategy used to achieve that objective is to compare the discriminant and predictive power of SFAS No. 69 signals or SFAS No. 69 signals combined with financial signals to that of financial signals alone. The research hypothesized that SFAS No. 69 signals by themselves or as supplmentary to financial signals have more discriminant and predictive ability for business failure in oil and gas industry than do financial signals alone. In order to test that hypothesis, the study used the multiple discriminant analysis technique (MDA) to develop three equations. The first is based on SFAS NO. 69 signals, the second on financial statement signals, and the third on joint financial and SFAS No. 69 signals. Data were collected from the 10-K's arid the annual reports of 28 oil and gas companies (14 failed and 14 nonfailed). The analysis was repeated for four time bases, one year before failure, two years before failure, three years before failure, and the average of the three years immediately before failure. After assessing the discriminant and predictive ability of each equation in the four time bases, a t-test was used to determine a significant difference in the discriminant ...

An Empirical Study of the Effectiveness of Independence Discrimination Resulting from the Application of Aicpa Ethical Interpretation 101-3--Accounting Services

Description: Interpretation 101-3 of the AICPA Code of Professional Ethics provides four independence requirements for certified public accountants performing bookkeeping services. As such, these requirements are largely thought of as rules requiring compliance. The purpose of this study was to provide empirical evidence related to the question, "Can the guidelines in Interpretation 101-3 be effectively interpreted?" Accordingly, the research objectives were twofold: (1) to make an estimate of the effectiveness of independence discrimination resulting from the use of Interpretation 101-3 , and (2) to identify variables related to differences in CPAs' judgements of impairment and non-impairment of CPA independence in situations covered by Interpretation 101-3. The research methodology for this study was based on a case approach. Twelve situations developed from analysis of Interpretation 101-3 and discussions with practitioners were organized into twenty-four cases in which a CPA firm provided a variety of accounting services. These twenty-four cases were divided into two case sets of twelve cases each and then combined with two cases from a previous study by David Lavin. These cases were submitted to an expert panel for validation as to their relationship to Interpretation 101-3, and a predetermined "correct" judgement was established for use in analysis. A mail survey of the licensees of the Texas State Board of Public Accountancy was used for collecting data. The CPAs were provided with a copy of Interpretation 101-3 and asked to base their judgements exclusively on the standard. Hypothesis testing was used to determine the effectiveness of the independence discrimination resulting from the use of Interpretation 101-3. Statistical models were developed for evaluating differences in the effectiveness of independence discrimination and differences in the CPAs' judgements themselves.

An Environmental Evaluation and Public Opinion Survey Concerning Park and Recreation Development in Flower Mound, Texas

Description: An environmental evaluation concerning land designated for park and recreation development was conducted in Flower Mound, Texas. Results were compared with the findings of a public opinion survey of the citizenry of Flower Mound. The first section is an introduction to land use and recreation planning. Section two presents a review of pertinent literature concerning environmental evaluation and recreation and recreation planning. Third is a brief description of Flower Mound, Texas, and existing park properties. The fourth section discusses both the environmental evaluation and the survey research techniques employed. Results of the environmental evaluation are examined in section five. The public opinion survey results are discussed in the sixth section. Flower Mound is fortunate to have a number of sites suitable for recreational development. If recreational development is to be successful and satisfactory to the users, decisions will need to be made in an organized fashion. Park and recreation planning should be incorporated within a general land use planning framework.

The Equity Method of Accounting and Unconsolidated Subsidiaries: An Empirical Study

Description: The objectives of this study are to determine the effect on certain financial statement relationships of using the equity method to account for subsidiaries in lieu of consolidation and to gather evidence to suggest whether or not bond rating agencies take into consideration these effects in rating corporate bonds. Sixty manufacturing companies listed in COMPUSTAT as having a subsidiary accounted for by the equity method compose the experimental group. The remaining manufacturing companies in COMPUSTAT compose the control group. Computation of eight variables from COMPUSTAT provided data from the companies' original financial statements. Consolidating the subsidiaries of the experimental companies using annual 10-K data made it possible to recompute the same eight variables with these subsidiaries consolidated into the parents' statements. Comparison of the variables for the companies before and after consolidation revealed that five of the eight variables were substantially different and that the differences were statistically significant. Horrigan's multiple regression bond rating model provided indirect evidence to examine which method (equity or consolidation) bond raters use in their rating process. The model is a surrogate for the rating process. Use of the model necessitated calculation of two sets of regression coefficients—one using data in which subsidiaries were accounted for by the equity method and a second when the subsidiaries are consolidated. A derivation sample drawn randomly from both the experimental and control groups provided the data for computation of the coefficients. Comparison of predictions using the two sets of coefficients and validation sample company data revealed that the consolidated method data generated predictions in greater agreement with Moody's bond ratings than did the equity method data. The N-probit technique indicated that the predictions of Horrigan's model are not biased. The research suggests that bond raters find data based on consolidation of subsidiaries more important in their analyses than ...

An Evaluation of the Views of Black Journalists Working at Black Newspapers Concerning the Effects of the Civil Rights Movement on Their Black Newspapers from 1960 to 1985

Description: This study was designed to determine whether black journalists who work at black newspapers in Texas felt the Civil Rights movement had affected their industry. Although black newspapers lost an exclusive market for talent that now must be shared with majority-owned newspapers, this report concludes that the operation of black newspapers virtually was unaffected by the Civil Rights movement. It is recommended that this research serve as a starting point for a continuing examination of black newspapers. It would be particularly beneficial if more information could be gathered from people who have worked at now-defunct black newspapers.

An Examination of an Integrative Expectancy Model for Auditors' Performance Behaviors Under Time Budget Pressure

Description: In recent years there has been a growing use of expectancy theory to study motivation and performance in accounting environments. Such research efforts have resulted in reporting some inconsistent findings and low explanatory power for the expectancy model. In an attempt to increase the explanatory power of the model, several researchers have suggested the inclusion of nonexpectancy components in the model. This research was undertaken to develop an integrative expectancy model by incorporating some elements of goal setting theory and attribution theory into the expectancy formulation. The study was also designed to provide empirical evidence on the validity of a within-subject design of the proposed model through an empirical investigation of auditors* performance behaviors to meet budgeted time in public accounting firms. Alternative performance behaviors to meet budgeted time were modeled in three choice processes. The first deals with auditors choice to report unfiltered time (i.e. report actual time worked) as opposed to filtered time worked (i.e., underreporting and sign-off behaviors). The second process deals with auditors' choice to engage in underreporting as opposed to sign-off behaviors. The third process deals with auditors' choice to reduce or overrule some audit procedures based on professional judgment. Data were collected using an anonymous questionnaire from a sample of auditors at the staff, senior, and supervisory staff levels of fifty-three national, regional and local accounting firms in the Dallas- Fort Worth area. Data received from 671 participants were analyzed using th Automatic Interaction Detector (AID3) and multiple regression techniques. The findings of this research support the expectancy formulation and its relevancy to the accounting environments. However, five nonexpectancy variables were found to have significant relationships with auditors' choice processes to meet budgeted time. These five variables were supervision, budget feasibility, length of experience, organizational level and firm size classification.

Excuses for the Universe

Description: We create fictions--personal and literary--to cope with fear, and it is our choice whether or not these inventions affirm life. This collection presents many ways of "making excuses for the universe," both from a personal standpoint and also by using the voices and visions of created characters. The collection contains a section of family poems and three sets of character poems: Beverly and Nanci, Strange Mary, and Blue Donna. Following each section are two related poems for transition or amplification. The poems show a progressive change in writing techniques, especially experimentation with sound, as well as pursuing the central theme that perception is a desirable goal, well worth the price.

An Existence Theorem for an Integral Equation

Description: The principal theorem of this thesis is a theorem by Peano on the existence of a solution to a certain integral equation. The two primary notions underlying this theorem are uniform convergence and equi-continuity. Theorems related to these two topics are proved in Chapter II. In Chapter III we state and prove a classical existence and uniqueness theorem for an integral equation. In Chapter IV we consider the approximation on certain functions by means of elementary expressions involving "bent line" functions. The last chapter, Chapter V, is the proof of the theorem by Peano mentioned above. Also included in this chapter is an example in which the integral equation has more than one solution. The first chapter sets forth basic definitions and theorems with which the reader should be acquainted.

Exoprotease Production by Aeromonas hydrophila in a Chemically Defined Medium

Description: Wretlind, Heden, and Wadstrom found ammonium sulfate to be inhibitory for the formation of extracellular protease in Aeromonas hydrophila grown in Brain Heart Infusion medium. They demonstrated by manipulating the iron and zinc content within their medium that it is possible to differentially affect the accumulation of hemolysin and protease by A. hydrophila grown in batch culture. Further manipulation of the composition of this medium was done in the present study to determine the effect of other components on the production of protease. The purpose of this study was to determine the factors affecting the level of A. hydrophila protease produced in a chemically defined medium.

An Exploratory Study of Curiosity in Three-, Four- and Five-Year-Old Children

Description: This study investigated the development of curiosity in young children. A previous study by Kreitler, Zigler, and Kreitler had identified five specific types of curiosity, manipulatory curiosity, perceptual curiosity, conceptual curiosity, curiosity about the complex, and adjustive-reactive curiosity. The basic problem was to describe the development of these five types of curiosity in three-, four-, and five-year-old children. A secondary problem was to determine if children follow a predictable pattern in their development of the five types of curiosity. Five tasks, measuring nineteen variables of curiosity, were administered individually to thirty three-year-olds, thirty four-year-olds, and thirty five-year-olds by a trained rater. Mean scores for each variable and each type of curiosity were calculated for each group.

Fairy Tale Elements in Margaret Atwood's Novels: Breaking the Magic Spell

Description: This thesis traces Margaret Atwood's uses of three major elements of fairy tales in her novels. Atwood creates a passive, fairy-tale-like heroine, but not for the purpose of showing how passivity wins the prince as in the traditional tale. Atwood also uses the binary system, which provides a moralistic structure in the fairy tale, to show the necessity of moving beyond its rigidity. In addition, Atwood's novels focus on transformation as the breaking of a spell. However, the spell to be broken arises out of the fairy tales themselves, which create unrealistic expectations. Thus, Atwood not only presents these fairy tale elements in a new setting, but she also changes their significance.

Family Environment, Affect, Ambivalence and Decisions About Unplanned Adolescent Pregnancy

Description: This study investigated the relationships among family environment, demographic measures, the decisions made by unintentionally pregnant adolescents regarding post-delivery plans (stay single, get married, adoption), and the certainty with which these decisions were made. The Information Sheet, Family Environment Scale (Moos & Moos, 1981), and Multiple Affect Adjective Check List (Zuckerman & Lubin, 1965a) were administered to 17 5 pregnant adolescents, ages 14 through 22, who intended to carry their pregnancies to term. Pearson product-moment correlations and multiple regression analyses were utilized to assess the relationships between family environment and certainty of decision and between family environment and negative affect. Greater uncertainty was associated with nonwhite racial status and living with both natural parents or mother only. Higher levels of negative affect were related to lower levels of perceived family cohesion, independence, expressiveness, and intellectualcultural orientation. The demographic variables of age, trimester of pregnancy, and family constellation were also found to be useful in predicting levels of negative affect. Subjects who were older, further along in their pregnancies, and living with both natural parents or mother only tended to report greater negative affect. Findings of greater uncertainty and negative affect associated with living with the natural mother are consistent with previous reports of disturbed mother-daughter relationships among this population. Discriminant analysis revealed that subjects choosing adoption were more likely to be older and to be white than those choosing to keep the child. They also tended to perceive higher levels of expressiveness and independence in their families. Comparisons between the present sample and "normal" families revealed differences which were statistically significant, but quite small in terms of raw score units. Indeed, these groups may be more similar than has often been assumed. The implications of these findings for the delivery of services and for future research efforts in this area ...

Food Habits, Dietary Overlap and Electivity of Non-Game Insectivorous Fishes in an Ozark Foothills Stream

Description: Etheostoma spectabile, E. punctulatum, and Cottus carolinae were sampled Mar., 1983, - Feb., 1984, in Flint Creek, Oklahoma. Immature E. spectabile ate primarily microcrustaceans, while mature fishes relied more on mayflies and amphipods. Juvenile E. punctulatum fed upon mayflies, amphipods, and Asellus. Mature E. punctulatum ate primarily mayflies, and other relatively larger prey. Cottus carolinae consumed chironomids almost exclusively in Jan. - Feb., 1984, while mayflies were predominant the remainder of the year. No significant habitat partitioning between the two darters, and seasonal habitat segregation between C. carolinae and the two darters was found. Dietary overlap between the darters was significantly correlated (p<0.0005) to differences in x prey sizes.

Garden of Eden

Description: The Garden Of Eden is a ballet for four instrumental quintets: brass, woodwind, string, and percussion. Each ensemble is associated with one of four dancers: God, Adam, Eve, -and the Serpent, respectively. The duration of this ballet is approximately sixteen minutes and is divided into three parts depicting (1) the creation of the world and Adam; (2) the creation of Eve-and the warning about the tree of knowledge; and (3) the Serpent's temptation of the main characters, as well as their subsequent banishment from the garden by God. One of my reasons for composing this work was to answer an important question: how to control musical motion and emotion. Since ballet incorporates both motion in its choreography and emotion in its program, it provided a perfect medium in which to work.

Gender Specific Reactions to Incest

Description: The problem of incest is beginning to receive a recognition and research attention long overdue. Becoming more evident is the prevalence and far reaching effects of incest. Currently, little distinction is made between the treatment approach for males and females, yet research indicates differences between the two sexes. This study explores possible differences between male and female incest victims in (1) their moral ethic, (2) their self-definition, (3) the basis from which they felt compelled to comply with the incestuous abuse, (4) the reasons they believed the sexual abuse was right or wrong, (5) the reasons for telling someone or keeping the incest a secret, (6) how they decided whether or not they made the right choice, (7) the manner in which they have changed since the abuse began, (8) the content and degree of their own guilt and/or lowered esteem, and (9) the ideas they have of changes which could have prevented the abuse.

Gothic Elements in Selected Fictional Works by Nathaniel Hawthorne

Description: Gothicism is the primary feature of Nathaniel Hawthorne's fiction, and it is his skill in elevating Gothicism to the level of high art which makes him a great artist. Gothic elements are divided into six categories: Objects, Beings, Mental States, Practices and Actions, Architecture and Places, and Nature. Some devices from these six categories are documented in three of Hawthorne's stories ("Young Goodman Brown," "The Minister's Black Veil," and "Ethan Brown") and three of his romances (The Scarlet Letter, The House of the Seven Gables, and The Marble Faun). The identification of 142 instances of Hawthorne's use of Gothic elements in the above works demonstrates that Hawthorne is fundamentally a Gothic writer.

A Graphical, Database-Querying Interface for Casual, Naive Computer Users

Description: This research is concerned with some aspects of the retrieval of information from database systems by casual, naive computer users. A "casual user" is defined as an individual who only wishes to execute queries perhaps once or twice a month, and a "naive user" is someone who has little or no expertise in operating a computer and, more specifically for the purposes of this study, is not practiced at querying a database. The research initially focuses on a specific group of casual, naive users, namely a group of clinicians, and analyzes their characteristics as they pertain to the retrieval of information from a computer database. The characteristics thus elicited are then used to create the requirements for a database interface that would, potentially, be acceptable to this group. An interface having the desired requirements is then proposed. This interface consists, from a user's perspective, of three basic components. A graphical model gives a picture of the database structure. Windows give the ability to view different areas of the database, physically group together items that come under one logical heading and provide the user with immediate access to the data item names used by the system. Finally, a natural language query language provides a means of entering a query in a syntax (that of ordinary English) which is familiar to the user. The graphical model is a logical abstraction of the database. Unlike other database interfaces, it is not constrained by the model (relational, hierarchical, network) underlying the database management system, with the one caveat that the graphical model should not imply any connections which cannot be supported by the management system. Versions of the interface are implemented on both eight-bit and sixteen-bit microcomputers, and testing is conducted in order to validate the acceptability of the interface and to discover the ...
