The Effects of Modeling, Roleplaying and Feedback on the Performance of Teachers of Children with Autism

The Effects of Modeling, Roleplaying and Feedback on the Performance of Teachers of Children with Autism

Date: August 1999
Creator: Edwards, Carla Ward
Description: Teachers providing treatment to children with autism are responsible for implementing numerous procedures. Teacher training has not been addressed extensively in the literature. This study employed a multiple baseline design to evaluate the effects of a training package incorporating modeling, roleplaying and feedback on teacher performance. Results indicated that the teacher implemented correct teaching episodes following training. Changes in teacher performance were only observed when the training package was applied to each setting and skill area. As a result of changes in teacher behavior, the child demonstrated an increase in the number of desired responses. Results are discussed in the context of generalization, training package components, cost-benefit of single-subject designs, and limitations of the study.

The Effects of Music Training on Electroencephalographic Coherence of Preschool Children

The Effects of Music Training on Electroencephalographic Coherence of Preschool Children

Date: August 1999
Creator: DeBeus, Roger J. (Roger John)
Description: The purpose of this study was to examine the effects of music training on electroencephalographic (EEG) coherence of preschool children. EEG coherence is a measurement of brain wave activity that reflects anatomical and neurophysiological parameters and functional connectivity between areas of the brain. Participants were 4- to 6-year-old children divided into two groups: one received music training for 20 minutes twice a week for 10 weeks while the other group served as controls. Nineteen channels of EEG data were collected from each child pre- and post-training. Data were collected from three conditions: eyes-open resting, listening to music, and performing the Object Assembly subtest of the Weschler Preschool and Primary Scale of Intelligence - Revised (1989). The hypothesis was that the music training group would show increased EEG coherence as compared to controls. The EEG data was reduced into seven bandwidths and analyzed separately for each condition. Multiple ANCOVAs were used to factor out pre-test variability and to maximize connectivity changes between the two groups. The dependent measures were the post-QEEG electrode pairs and the covariates were the pre-QEEG electrode pairs. Results indicated the eyes-open and listening to music conditions showed more significant changes between the groups than the Object Assembly ...

Effects of Psychoeducation on Opinions about Mental Illness, Attitudes toward Help Seeking, and Expectations about Psychotherapy

Effects of Psychoeducation on Opinions about Mental Illness, Attitudes toward Help Seeking, and Expectations about Psychotherapy

Date: August 1999
Creator: Gonzalez, Jodi Marie
Description: The effect of psychoeducation on opinions about mental illness, attitudes toward help seeking, and expectations about psychotherapy were investigated. One group served as a control, one group read a written lecture on information about mental illness, and one group read a written lecture on information about psychotherapy. The control group, and experimental groups immediately after reading the lecture, completed demographic information, Attitudes Toward Help Seeking-Short Form, Expectations About Counseling-Brief Form, Nunnally Conceptions of Mental Illness Questionnaire, and three College Adjustment Scales (Depression, Anxiety, Self Esteem). Participants were asked to complete the same measures four weeks after the initial assessment. Results: No significant improvement in attitudes toward help seeking was demonstrated in either experimental group, at either time of testing. Expectations about psychotherapy were significantly improved in both experimental groups, which remained significant at Time 2. Opinions about mental illness demonstrated an immediate significant improvement in attitudes with the mental illness lecture group, however this effect did not remain at Time 2. The psychotherapy lecture group did not have significantly improved opinions about mental illness at either time of testing. The control group did not produce any significant changes between Time 1 and Time 2 testing. Experimental group scores demonstrated similarity ...

Ethnic identity, gay identity and sexual sensation seeking: HIV risk-taking predictors among men of color who have sex with men

Ethnic identity, gay identity and sexual sensation seeking: HIV risk-taking predictors among men of color who have sex with men

Date: August 1999
Creator: Géliga-Vargas, Jesús A.
Description: This study examined relationships among ethnic identity, gay identity, sexual sensation seeking, and HIV risk-taking behaviors among 302 men of color recruited from gay bars, bathhouses, community agencies, and the 1998 United States Conference on AIDS. The sample included 24% African American, 28% Latino, 25% Asian/ Pacific Islander, 19% Caucasian, 1% American Indian, and 3% other ethnicity. Logistic regression analysis identified sexual sensation seeking, having an undefined gay identity, being in a sexually exclusive relationship, not being HIV seronegative, and length of stay in the country (for those born overseas) as significant predictors of unprotected anal intercourse (insertive and penetrative) among men of color who have sex with men.

Exhibit Eh: Canadian Dependency, U. S. Hegemony, and the Amorphousness of English Canadian Culture

Exhibit Eh: Canadian Dependency, U. S. Hegemony, and the Amorphousness of English Canadian Culture

Date: August 1999
Creator: McIntosh, Andrew
Description: This thesis begins by examining the factors that have resulted in the dependent nature of Canada's political and economic structure, and proceeds to examine how this has contributed to the cultural amorphousness of English Canadian identity. The hegemonic authority of American and trans-national interests, established and maintained in the cultural sphere through the extensive monopoly of the distribution of cultural and media products, perpetuates the amorphousness of English Canadian culture through the appropriation of Canadian space by the international image industry. Such categorization of Canadian space reflects and perpetuates the imaginary representation of Canada within the dominant ideology as an indistinct and amorphous entity, and comes to usurp the materiality that constructs the lived identities of English Canadians.

Explorations with polycarbocyclic cage compounds

Explorations with polycarbocyclic cage compounds

Date: August 1999
Creator: Chong, Hyun-Soon
Description: A variety of novel cage-functionalized pyridyl containing crown ethers have been prepared for use in selective alkali metal complexation studies. A highly preorganized, cage-functionalized cryptand also has been designed and has been synthesized for use as a selective Li+ complexant. The alkali metal picrate extraction profiles of these cage-functionalized crown ethers also have been studied. Novel cage-functionalized diazacrown ethers have been prepared for selective alkali metal complexation studies. Alkali metal picrate extraction experiments have been performed by using this new class of synthetic ionophores to investigate the effects of cage-annulation and the influence of N-pivot lariat sidearms upon their resulting complexation properties. Novel pyridyl containing calix[4]arene receptors were prepared. Analysis of their respective 1H NMR and 13C NMR spectra suggests that calix[4]arene moieties in the ligand occupy the cone conformation. The complexation properties of these host molecules were estimated by performing a series of alkali metal picrate extraction experiments. An optically active cage-functionalized crown ether which contains a binaphthyl moiety as the chiral unit was prepared. The ability of the resulting optically active crown ether to distinguish between enantiomers of guest ammonium ions (i.e., phenylethylamonium and phenylglycinate salts) in transport experiments was investigated. Hexacyclo[11.2.1.02,12.05,10.05,15.010,14]hexadeca-6,8-diene-4,11-dione was prepared from hexacyclo[7.4.2.01,9.03,7.04,14.06,15] pentadeca-10,12-diene-2,8-dione. Unanticipated ...

Father Absence, Onset of Menarche, and Body Dissatisfaction: Importance of Father Absence

Father Absence, Onset of Menarche, and Body Dissatisfaction: Importance of Father Absence

Date: August 1999
Creator: Gartrell, Stacey R.
Description: Relationships between body dissatisfaction, dieting methods, father absence, and puberty timing were investigated in this study. Participants included adolescent females from Wave 1 of the National Longitudinal Survey of Adolescent Health. Logistic regression results indicated that girls without a biological father in the home were significantly more likely to have an early onset of puberty than on-time or late. Girls who experienced early puberty exhibited higher levels of body dissatisfaction, but didn't use more dieting methods. Early onset girls more likely used dieting methods if their biological father was present than absent; however, no significant difference in body dissatisfaction was shown. A negative relationship with fathers indicated more body dissatisfaction. None of the attained findings were found when the biological mother was absent, and having a stepfather did not seem to matter. Evidence was revealed that fathers play a role in their daughters' view of their own bodies.

The Fourteen Seréstas of Heitor Villa-Lobos (1887-1959)

The Fourteen Seréstas of Heitor Villa-Lobos (1887-1959)

Date: August 1999
Creator: Sánchez, Noé
Description: The Fourteen Seréstas of Heitor Villa-Lobos comprise a group of songs that expresses Villa-Lobos's compositional technique for the voice. These songs are challenging as a topic because not much historical or analytical research has been done on them. I approach the topic by providing historical background on the modinha and how it relates to the serésta. This is followed by a descriptive analysis in the order of the set, which includes musical examples, chart diagrams, and comparisons of the seréstas to other works. I hope to have contributed valuable information to the research of these songs since Villa-Lobos wrote over ninety solo vocal songs which still await analysis and discussion. This thesis is a contribution toward narrowing this gap.

Fractional Integration and Political Modeling

Fractional Integration and Political Modeling

Date: August 1999
Creator: Lebo, Matthew Jonathan
Description: This dissertation investigates the consequences of fractional dynamics for political modeling. Using Monte Carlo analyses, Chapters II and III investigate the threats to statistical inference posed by including fractionally integrated variables in bivariate and multivariate regressions. Fractional differencing is the most appropriate tool to guard against spurious regressions and other threats to inference. Using fractional differencing, multivariate models of British politics are developed in Chapter IV to compare competing theories regarding which subjective measure of economic evaluations best predicts support levels for the governing party; egocentric measures outperform sociotropic measures. The concept of fractional cointegration is discussed and the value of fractionally integrated error correction mechanisms are both discussed and demonstrated in models of Conservative party support. In Chapter V models of presidential approval in the United States are reconfigured in light of the possibilities of fractionally integrated variables. In both the British and American case accounting for the fractional character of all variables allows the development of more accurate multivariate models.
