Parents' Understanding of Developmentally Appropriate Practice in Early Childhood Education

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.

Comparative Mitochondrial DNA Sequence Diversity in Isolated and Open Populations of Southern Flying Squirrels

Description: Three populations of Southern flying squirrels were studied in the Ouachita Mountains of Arkansas to assess the impact of population subdivision-due to island formation--on the population genetics of Glaucomys volans. One island, one mainland, and one open population were investigated. A 367 nucleotide hypervariable region of mitochondrial DNA was sequenced in individuals from each population. Individuals and populations were compared to assess relatedness. Higher sequence diversity was detected in the open and island populations. One island individual shared characters with both the island and mainland populations. Results support the hypothesis that the mainland population may have reduced gene flow. Also, the island population may have been originally founded by at least two maternal lineages.

A Multimedia Atlas of Dissection for Comparative Anatomy of the Vertebrates

Description: Traditional methods of teaching the laboratory course for Comparative Anatomy of the Vertebrates could be improved by applying current computer technology to construct an interactive, multimedial atlas of dissection. Five specimens used in comparative anatomy courses at most institutions were chosen as representative members of the Phylum Chordata: amphioxus, lamprey, dogfish shark, mud puppy, and cat. Specimens were dissected according to the modified method of Wischnitzer, 1993, and each stage was photographed with a Kodak DC120 digital zoom camera. These images were processed on a Power Macintosh 7600 computer with Adobe Photoshop v. 5.0. The atlas was constructed from these images using Macromedia Authorware v. 4.0.3. Each image contains a series of interactive objects that display a highlight and descriptive text as the cursor passes over each object.

Harbor: The Act of Autobiography

Description: This written thesis accompanies a sixteen-minute documentary video, Harbor, in which the filmmaker explores her relationship with her father who has suffered a stroke. Detailed accounts of the pre-production, production and post-production of the video allow the reader to understand the challenging and rewarding process of making an autobiographical documentary. Theoretical issues are also discussed, including the validity, criticisms, artistic nature and ethical concerns of autobiographical filmmaking. The filmmaker stresses the universality of her story, and how, despite the film's very personal nature, it is applicable for anyone who has dealt with the illness and/or disability of a parent.

Development of a Coaxiality Indicator

Description: The geometric dimensioning and tolerancing concept of coaxiality is often required by design engineers for balance of rotating parts and precision mating parts. In current practice, it is difficult for manufacturers to measure coaxiality quickly and inexpensively. This study examines feasibility of a manually-operated, mechanical device combined with formulae to indicate coaxiality of a test specimen. The author designs, fabricates, and tests the system for measuring coaxiality of holes machined in a steel test piece. Gage Repeatability and Reproducibility (gage R&R) and univariate analysis of variance is performed in accordance with Measurement System Analysis published by AIAG. Results indicate significant design flaws exist in the current configuration of the device; observed values vary greatly with operator technique. Suggestions for device improvements conclude the research.

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques

Description: Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4’-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC). The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC and temperature-modulated DSC (TMDSC), thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram for rapid determination of processing parameters in the processing of prepregs.

Hospitality Students' Attitudes and Behavioral Intentions toward Learning and Using Computer Technology

Description: Following Ajzen/Fishbein's 1980 Theory of Reasoned Action, influences of hospitality students' external variables (age, gender, university classification, and work experience) on computer attitudes, and relationships between computer attitudes and intentions to learn and use computers were tested. A sample of 412 hospitality students completed two measurements: Loyd/Gressard's 1984 Computer Attitude Scale, and Behavioral Intentions to Learn and Use Computers. Males and females had positive computer attitudes. Graduates had more positive computer attitudes. No interaction effect existed between gender and classification. No relationships existed between age and work experience on computer attitudes. Computer attitudes positively correlated with intentions to learn and use computers. Results supported the Theory of Reasoned Action. External variables partially influence attitudes and attitudes influence intentions.

Techniques of Sensual Perception: The Creation of Emotional Pathways

Description: Some artists strive to create artwork that has aesthetic value. If a piece of artwork has the ability to capture the attention of an audience, it must contain strong sensual attributes. Thus, understanding how to design an art form to contain strong sensual attributes may increase the possibility of an aesthetic experience. Since aesthetics is an experience of sensations perceived when in contact with a creative form in any artistic discipline, it is necessary for an artist to understand the nature of the sensual experience. In understanding the sensual experience, artists may be able to create techniques to enhance the aesthetic experience of their work. My video piece, entitled Ararat is a study of methods to enhance the sensual experience. I hope to accomplish this by means of using techniques that optimize an audience's perceptual experience.

The Luxury of Tears: A Secondary Survivor's Story

Description: As the written accompaniment for The Luxury of Tears, a twelve-minute documentary video exploring the emotional impact of sexual assault on male survivors and their partners, this document examines the visual texts of both the fiction and nonfiction genres. Specifically, I contend that fiction film manufactures male survivorship with regard to rape events in such manner which contributes to the thematization of social silence. Such silence perpetuates the feminization of rape as a social problem, and dissolves the development of male survivor resources. A discussion of production processes, challenges, and resolutions is included.

The Potential of Coelomocyte Chemotaxis as an Immune Biomarker in the Earthworm, Lumbricus terrestris

Description: Coelomocyte migration responses, both random and chemotatic, were examined in the earthworm Lumbricus terrestris. Coelomocyte random migration patterns towards non-stimulatory, non-chemotatic solutions were described. Migration responses to immunostimulatory agents lipopolysaccharides (LPS), N-formly-methionyl-leucyl-phenylalanine (FMLP), sheep erythrocytes, Saccharomyces cerevisiae, Aeromonas hydrophila, Eisenia fetida and Rhabditis pellio were characterized. Chemotaxis was reported to LPS, FMLP, sheep erythrocytes, S. cerivesae and E. fetida. Bio-indicator potential of chemotaxis is discussed relative to variability in migration responses.

As Darkness Falls: A Composition for Wind Ensemble

Description: As Darkness Falls is a composition that explores our interaction with several aspects of darkness through the use of musical imagery. The imagery attempts to reflect the moods, feelings, and impressions of a person as he or she interacts with darkness. The non-programmatic character of the composition allows listeners to superimpose their own experiences onto the musical tapestry in order to manifest a personal connection between the listener and the music. As Darkness Falls is a composition scored for a minimum instrumentation of piccolo, 6 flutes, 3 oboes, 3 bassoons, 9 B-flat clarinets, B-flat bass clarinet, 2 E-flat alto saxophones, B-flat tenor saxophone, E-flat baritone saxophone, 4 B-flat trumpets, 4 horns in F, 3 tenor trombones, bass trombone, 2 euphoniums, 2 tubas, timpani, and 4 percussionists. The music consists of three movements (slow-slow-fast) lasting a total of approximately seventeen minutes. The duration of each of the three movements is six minutes, four and one-half minutes, and six and one-half minutes, respectively. The document also contains an analysis of the work by the composer. The analysis explores the compositional style of the work, focusing on musical aspects within each movement that were governing parameters in the compositional process.

Evidentiary Value of Condoms: Comparison of Durable Physical and Chemical Characteristics of Condoms

Description: Condom trace evidence must not be overlooked in sexual assault cases; understanding the chemical and physical characteristics of condoms is imperative if condoms are to be useful evidence. Previous research shows that condom identification is possible, but it is equally important to evaluate durability of condom residues versus time. Using FT-IR, this study examined vaginal swabs from subjects who self-sampled at intervals for up to 72 hours after having intercourse with a condom. This study investigated whether age and the stage of the menstrual cycle affected the durability of residues in the vagina over time. This study revealed that condoms containing nonoxynol-9, silicone-based lubricants, and particulates provide valuable information for identification, and that nonoxynol-9 specifically withstands the vaginal environment for up to 72 hours. Additionally, age and menstrual cycle both appeared to have an effect on the durability of residues although larger sample size is desirable.

Parents' Beliefs and Knowledge Regarding Child Development and Appropriate Early Childhood Classroom Practices

Description: The intent of this study was to assess low-income parents knowledge and beliefs regarding child development and appropriate classroom practice and to compare their responses with those obtained from a previous survey of upper-income parents (Grebe, 1998). This study group (N=21) consisted of parents or guardians with children in a federally subsidized child-care center. Results indicated a high level of knowledge regarding developmentally appropriate practice and child development. Overall, there were no significant differences in the knowledge between the two income-levels, however, responses to several questions revealed slight differences in beliefs.

Depression, Anxiety, Self-Esteem, and Coping in Children and Adolescents Newly Diagnosed with Cancer and Children and Adolescents on Cancer Treatment for a Period of Seven Months or Longer

Description: Differences in self-reported depression, anxiety, self-esteem, and coping were evaluated in two groups of pediatric oncology patients: newly diagnosed (less than six months post-diagnosis) (n=5) and patients on cancer treatment for seven months or longer (n=5). Participants (6 males, 4 females, ages 7-17 years) completed the Children's Depression Inventory (CDI), the State-Trait Anxiety Inventory for Children (STAIC), and the Culture-Free Self-Esteem Inventory (CFSEI-2); nine of the ten participants discussed in a semi-structured interview their personal experiences and feelings about having cancer. Although the newly diagnosed group had a higher mean score on the CDI than the 7 months or greater group, the difference was not significant (p = .054). The newly diagnosed group also had higher mean state and trait anxiety scores on the STAIC, indicating higher anxiety levels, and a slightly lower CFSEI-2 mean score, indicating slightly lower self-esteem than the 7 months or greater group, but differences were not at a statistically significant level (p>.05).

An Analysis of the Composition Process of Bartók's Eight Improvisations on Hungarian Peasant Songs, Op. 20

Description: This is a study of Bartók's compositional process as it relates to the Improvisations, Op. 20. The study, which focuses on the analysis of the draft manuscript 50PS1, compares the draft and other relevant sources with the final composition. Bartók's framework for the entire Improvisations is based on a compositional strategy of pairing individual improvisations combined with systematic revision of the draft copy by the introduction of tritones as tonal equivalents and movement by fifths from semitones, to achieve structural coherence in the individual improvisations. The tonic-dominant relationship is used to rearrange the individual improvisations in the draft and tritones as tonal equivalents are used to propel the movement between the improvisations to produce a coherent whole.

Utilization of the family medical leave act: A case study

Description: American businesses have confronted a changing world economy marked by increasing competition , technological innovation, and instability. Many more women have entered the labor force. Many families' caregiving needs are now being met by family members who also are holding down jobs. This, in turn, has fueled the rising need among employees for workplace policies that enable them to meet the often competing demands of job and home. In 1993, Congress passed the Family and Medical Leave Act (FMLA of the Act) to provide a national policy that supports families in their efforts to strike a workable balance between the competing demands of the workplace and the home. The objective of this study is to examine the amount of FMLA lost time at one particular company in order to determine a demographic and job characteristic profile of employees who take time away from their jobs for reasons that are protected by the Act.

The Reformation-Era Church Courts of England: A Study of the Acta of the Archidiaconal and Consistory Court at Chester, 1540-1542

Description: Much work has been done over the last fifty years in the study of the English ecclesiastical courts. One court that thus far has escaped much significant scholarly attention, however, is the one located in Chester, England. The author analyzes the acta of that court in order to determine what types of cases were being heard during the years 1540-42. His analysis shows that the Chester court did not deviate significantly from the general legal and theological structure and function of Tudor church courts of the period.

Macroinvertebrate Community Structure as an Indicator of Watershed Health in the Upper Trinity River Basin, North Central Texas

Description: This study describes macroinvertebrate community structure and assesses its potential in detecting point and non-point sources of disturbance associated with rural and urban areas in the Upper Trinity River Basin. Geospatial techniques were used to quantify landuse within the watershed in a GIS. At rural sites near the headwaters of the Trinity River, collector-gathering burrowers that are adapted to minimal flow comprised the majority of taxa. Destinies of taxa compositions at downstream sites increased and shifted toward psammophilic and rheophilic invertebrates, including primarily collector-filtering clingers, that are characteristic of shifting sand habitats in large prairie rivers. Benthic community structure generally benefited from point source impacts including wastewater treatment plant effluents that maintained higher flow. Community indices were negatively associated with forest landuse and positively associated with urban landuse. Partial CCA determined that flow and landuse contributed equally to species dispersions. Comparisons with historical biomonitoring studies in upper Trinity River Basin indicate improved watershed health.

Stretched Out On Her Grave: The Evolution of a Perversion

Description: The word "necrophilia" brings a particular definition readily to mind – that of an act of sexual intercourse with a corpse, probably a female corpse at that. But the definition of the word did not always have this connotation; quite literally the word means "love of the dead," or "a morbid attraction to death." An examination of nineteenth-century literature reveals a gradual change in relationships between the living and the dead, culminating in the sexualized representation of corpses at the close of the century. The works examined for necrophilic content are: Mary Wollstonecraft’s Mary, A Fiction, Mary Shelley’s Frankenstein, Emily Brontë’s Wuthering Heights, and Bram Stoker’s Dracula and The Jewel of Seven Stars.

Inquiry-based science for high school students: a forensic unit

Description: This project constitutes an instructional unit for honors biology that involves the use of science in the field of criminal investigation and forensics. Before beginning the unit, the learners should have mastered basic laboratory skills, including use of the microscope. They should also have an understanding of the basic structure and function of DNA and its role in heredity and protein synthesis. The standard time frame is 24 days with 70-minute periods, but can be easily adjusted to meet classroom needs. Several instructional strategies enhance student learning and make science fun. The unit is inquiry-driven and activity-based. Students are surprised by the crime, gather and analyze evidence, and work towards proposing an explanation. This real world problem involves the use of cooperative learning and a variety of assessment techniques.

Characterizing the Municipal Solid Waste Stream in Denton, Texas

Description: Forty-two commercially collected dumpsters from Denton’s Municipal Solid Waste Stream were emptied, sorted and weighed to characterize the material types and make preliminary recycling policy recommendations. The general composition of Denton’s solid waste stream was not significantly different from the composition of the nation’s solid waste stream. Fifty-eight percent of the observed waste stream was recyclable. Paper made up the largest portion of recyclable materials and the "grocery" source category had more paper than any of the other five categories. Based on these findings, an incrementally aggressive approach is recommended to reduce certain types of wastes observed in the waste stream. This would include a Pay-As-You-Throw Program followed by an Intermediate Processing Center that can be converted to a Materials Recovery Facility.
