An Investigation of the Efficacy of Play Therapy with Young Children

An Investigation of the Efficacy of Play Therapy with Young Children

Date: May 1999
Creator: Brandt, Marielle Aloyse
Description: This study was designed to determine the effectiveness of play therapy as a method of intervention for children with a variety of emotional and behavioral problems. Specifically, the study was aimed at determining the effectiveness of play therapy in: (a) improving self-concepts of children with adjustment difficulties; (b) reducing internalizing behavior problems, such as withdrawal, somatic complaints, anxiety, and depression; (c) reducing externalizing behavioral problems such as aggression and delinquent behaviors; (d) reducing overall behavior problems, social problems, thought problems, and attention problems of children with adjustment difficulties; and (e) reducing parenting stress of parents of children who were experiencing adjustment difficulties.The experimental group consisted of 15 children who were experiencing a variety of adjustment difficulties and received play therapy once per week for 7 to 10 weeks. The control group consisted of 14 children who were experiencing a variety of adjustment difficulties and who were on a waiting list to receive intervention, and therefore, did not receive any treatment during the time of data collection. Experimental and control group children were administered the Joseph Pre-School and Primary Self-Concept Screening Test and parents of all participants completed the Child Behavior Checklist and the Parenting Stress Index at pretest and posttest ...

Photoelectric Emission Measurements for CVD Grown Polycrystalline Diamond Films

Photoelectric Emission Measurements for CVD Grown Polycrystalline Diamond Films

Date: August 1999
Creator: Hassan, Tarek
Description: We examined CVD grown polycrystalline diamond films having different methane concentrations to detect defects and study the possible correlation between the methane concentration used during the growth process and the defect density. SEM and Raman results show that the amorphous and sp2 carbon content of the films increases with methane concentration. Furthermore, photoelectric emission from diamond is confirmed to be a two-photon process, hence the electrons are emitted from normally unoccupied states. We found that the photoelectric yield, for our samples, decreases with the increase in methane concentration. This trend can be accounted for in two different ways: either the types of defects observed in this experiment decrease in density as the methane concentration increases; or, the defect density stays the same or increases, but the increase in methane concentration leads to an increase in the electron affinity, which reduces the overall photoelectric yield.

Ethnically mixed individuals: Cultural homelessness or multicultural integration?

Ethnically mixed individuals: Cultural homelessness or multicultural integration?

Date: May 1999
Creator: Navarrete-Vivero, Veronica
Description: Studies addressing racial/ethnic identity development have often overlooked the developmental cultural context. The impact of growing up with contradictory cultures has not been well explored. Immersion in multiple cultures may produce mixed patterns of strengths deficits. This study reviews the literature's currently inconsistent usage of the terms race, ethnicity, and culture; introduces the concept and theoretical framework of Cultural Homelessness; relates CH to multicultural integration; and develops two study-specific measures (included) to examine the construct validity of CH. The sample’s (N = 448, 67% women) racial, ethnic, and cultural mixture was coded back three generations using complex coding criteria. Empirical findings supported the CH-specific pattern of cognitive and social strengths with emotional difficulties: social adaptability and cross-cultural competence but also low self-esteem and shame regarding diff

A Different Drummer: A Chamber Opera

A Different Drummer: A Chamber Opera

Access: Use of this item is restricted to the UNT Community.
Date: May 1999
Creator: Friedman, Arnold Jacob
Description: A Different Drummer is a chamber opera adaptation of Donald Davis's story "A Different Drummer" from his collection Listening for the Crack of Dawn, published by August House. The opera lasts about seventy minutes, and calls for a cast of three and an orchestra of sixteen players. It contains a prologue, epilogue and four scenes in a single act. The score is prefaced by a paper describing the musical strategies employed in setting the story as an opera. Three chapters describe the adaptation from short story to opera, the essential musical elements, and details of the application of the musical elements in each scene of the opera. The libretto is presented in the fourth chapter.

Nucleotide Inhibition of Glyoxalase II

Nucleotide Inhibition of Glyoxalase II

Date: May 1999
Creator: Gillis, Glen S
Description: The glyoxalase system mediates the conversion of methylglyoxal, a toxic ketoaldehyde, to D-lactic acid. The system is composed of two enzymes, glyoxalase I (Glo-I) and glyoxalase II (Glo-II), and exhibits an absolute requirement for a catalytic quantity of glutathione (GSH). Glo-I catalyzes the isomerization of a hemithioacetal, formed non-enzymatically from methylglyoxal and GSH, to the corresponding a -D-hydroxyacid thioester, s-D-lactoylglutathione (SLG). Glo-II catalyzes the irreversible breakdown of SLG to D-lactate and GSH. We have observed that ATP or GTP significantly inhibits the Glo-II activity of tissue homogenates from various sources. We have developed a rapid, one step chromatography procedure to purify Glo-II such that the purified enzyme remains "sensitive" to inhibition by ATP or GTP (Glo-II-s). Studies indicate that inhibition of Glo-II-s by nucleotides is restricted to ATP, GTP, ADP, and GDP, with ATP appearing most effective. Kinetics studies have shown that ATP acts as a partial non-competitive inhibitor of Glo-II-s activity, and further suggest that two kinetically distinguishable forms of the enzyme exist. The sensitivity of pure Glo-II-s to nucleotide inhibition is slowly lost on storage even at -80° C. This loss is accelerated at higher temperatures or in the presence of ATP. Kinetics studies on the resultant "insensitive" ...

Attribution to deviant and nondeviant social roles.

Attribution to deviant and nondeviant social roles.

Date: May 1999
Creator: Rohlman, James E.
Description: A questionnaire was used to study causal attribution to social roles as influenced by perceived deviance of the role, instructions to identify with the role, and participant gender. The perceived deviance or nondeviance of the roles was determined by a pilot study. The roles were varied randomly through 12 hypothetical events, and identification or nonidentification instructions randomly assigned. The participants were 194 male and female university students. Participants gave the cause of each event and rated the cause on five dimensions: internality, externality, stability, globality, and controllability. Causal attribution to deviant social roles was found to result in a significantly higher across-scales score and to be more internal, less external, and more global than attribution to nondeviant roles. Participant gender showed an interaction with deviance overall and on the dimensions of stability and globality due to significantly higher ratings by women participants than those by men. Identification instructions did not produce a significant effect.

Parents' understanding of developmentally appropriate practice in early childhood education.

Parents' understanding of developmentally appropriate practice in early childhood education.

Access: Use of this item is restricted to the UNT Community.
Date: May 1999
Creator: Grebe, Julie M.
Description: The intent of this study was to determine what understanding and knowledge parents had of developmentally appropriate practice (DAP). The study examined whether the beliefs of parents who enrolled their children in a National Association for the Education of Young Children (NAEYC) accredited program had any impact on their expectations for a philosophy and curriculum that is centered around DAP. In addition, the study examined whether parents' understanding of DAP changed when their children transitioned from infant and toddler programs, to preschool. The study group consisted of parents with children in two privately owned NAEYC accredited centers in 1998 (N=131). Results from parent reports indicated a high level of parent knowledge regarding DAP.

What Spins Away

What Spins Away

Date: May 1999
Creator: Irwin, Keith
Description: What Spins Away is a novel about a man named Caleb who, in the process, of searching for a brother who has been missing for ten years, discovers that his inability to commit to a job or his primary relationships is both the result of his history with that older missing brother, and his own misconceptions about the meaning of that history. On a formal level, the novel explores the ability of traditional narrative structures to carry postmodern themes. The theme, in this case, is the struggle for a stable identity when there is no stable community against which or in relationship to an identity might be defined.

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.
