The purpose of this thesis was to relate experiences and philosophies of James Surls to his art in order to determine changes in his artistic style. The problem was to study Surls' sculpture in approximately one decade in order to determine changes in his style, to determine which sculptures are important in making these changes, and to analyze how and why these changes occurred.

The purpose of this research was to study children's ability to recognize partially occluded images. Tasks were constructed which consisted of occluded images from video games, trademarks, and household objects. The tasks were administered to third and sixth grade students at two elementary schools in Arlington, Texas. The researcher discovered no significant differences between the scores of males and females except for the males' higher score on the video game task .

The problem with which this thesis is concerned is that of writing and directing an adaptation of the classic fairy tale, Cinderella. This study is a culmination of research on children's theatre, and the writing and producing of children's plays. The research led to the writing of the first draft of Cindy's Feller, an adaptation of Cinderella, beginning with a scenario which utilized a country-western theme. Upon completion of the first draft, the play was produced at North Texas State University during the summer of 1981. Stage directions of the play, a director's log of daily rehearsals, and an evaluation of the final productions were recorded to provide a stimulus for the writing of a final draft of Cindy's Feller and the preparation of this thesis.

Cell cultures were examined for percentage of fragile sites seen in straight-stained, Q-stained and reverse fluorescent-stained preparations. In all cases, percentage of fragile site expression was decreased when compared to straight-stained preparations. However, fragile sites seen in Q- and RF-stain could be identified as on X chromosomes.

The work presented here included the development of a highly sensitive method to estimate the size and complexity of poly(ADP-ribose). This involved radiolabeling of the precursor pools, purification of polymers using a boronate resin, polymer fractionation according to size by molecular sieve chromatography and analysis of polymer complexity by enzymatic digestion to nucleotides which were quantified by strong anion exchange chromatography.

The problem of this study was to conduct a systematic application and evaluation of the appropriateness of a computerized voice control system with a subject having the severe multihandicaps of profound mental retardation, quadriplegia, and limited communication skills. This research was an effort to establish if a computer could compensate for some of the physical limitations of the subject.

Several researchers have suggested that fluctuating estrogen levels may be responsible for certain physiological changes in the female body. The purpose of this study was to determine whether significant changes in the soprano voice quality occur due to the use of oral contraceptives.

Heinrich Zille (1858-1929), an artist whose creative vision was concentrated on Berlin's working class , portrayed urban life with devastating accuracy and earthy humor. His direct and often crude rendering linked his drawing and prints with other artists who avoided sentimentality and idealization in their works.

In Memoriam H. W. Reese is written for chamber orchestra and small mixed chorus, in honor of the composer's father, Hardy W. Reese (March 22, 1926-Nov. 23, 1982). The piece is written in one continuous movement with a total duration of approximately fifteen minutes. Within the work there are three distinct sections, each on texts dealing with a different stage in the process of reconciliation with death.

Two species of cyanobacteria (Fischeralla sp. 29161 and Phormidium autumnale) and one species of green algae (Fritschiella tuberosa) were found to promote survival of Legionella pneumophila in mineral salts medium cocultures. During the early stage of incubation Fischerella sp. supported growth of Legionella pneumophila even though the bacteria would not grow in the algae-free basal medium.

Carotenoids in W. dermatitids were found to be associated with membranes of lipid globules and/or proteins dispersed in the lipids in the yeast-phase of the organism. The lipid globules increase in size and the pigment concentrations increase with age of the cell. Electron micrographs show these organelles to be surrounded by a single unit membrane. The free carotenoids are extractable with ethyl ether from pigmented fractions of osmotically ruptured protoplasts only after the sample has been treated with acetone, indicating the pigment is non-covalently bound, presumably to a protein.

Histone proteins were examined during development in the meiotic elongate and a genetically close line N6HT. Histones were also extracted from an F1 (el x N6Ht). Comparisonc beteen the histone samples from each line of N6HT and elongate, and the F1 for leaf, root, and stem were inconclusive. A tassel sample form elongate exhibited a markedly slower migrating band that was not present in N6HT. The histone profiles of elongate and N6HT also differed. Each line N6HT and elongate exhibited three protein bands in the H1 region. Maize histone samples have been shown to exhibit four major H1 bands. The possibility exists that an H1 protein altered in its molecular weight and possibly in its interaction with the chromosome is present in elongate.

Missa Salve Regina, a five movement work, is approximately twenty minutes in duration. The work is a setting of the Ordinary of the Mass in Latin with additional text in the vernacular drawn from the writings of Miguel de Unamuno. The composition is scored for four speaking soloists (SATB), mixed chorus (SATB, percussion (player 1: tam tam, three suspended cymbal, bass drum, three tom-toms, glockenspiel, maracas, and marimba), and digital synthesizer optionally on tape. The Missa Salve Regina is concerned with the spiritual implications of the mass and its ritual. The music is composed for both concert presentation and use within the liturgy and deals with the conflict between faith and reason in the human mind, discussed at length, by Unamuno.

Glycogen synthase, the enzyme that catalyzes the rate-limiting reaction of glycogen syntheses has been purified and characterized from Ascaris suum muscle. Glycogen in the crude extract was digested to release the enzyme, eluted from a DE52 cellulose column and then applied to a Sepharose affinity column. The purified Ascaris enzyme was found to be homologous to the mammalian enzyme with regard to subunit and holoenzyme Mr^3 allosteric activation, substrate affinity and covalent modification. However, the association between Ascaris glycogen synthase and endogenous glycogen differed from that in mammalian systems.

One characteristic of abused children that is often observed but not yet empirically examined is social hypervigilance. In this study, 20 abused and 20 distressed children were compared using WISC-R subtests, two measures of locus of control and need for attention.

Score based on on a story from Fun With Your New Head, by Thomas M. Disch.

The Squirrel Cage is an intermedia composition set in three scenes and two interludes. The composition is based on the short story "The Squirrel Cage" by Thomas M. Disch. Robin Kay Willoughby created the libretto for the composition. The drama for The Squirrel Cage focuses on the actor who is being held captive in a white, padded cell. He does not know how long he has been in the cell or even why he is being held. His only source of stimulation is through the broadcast of National Public Radio that he hears in his cell. The only way he can attempt to communicate with the outside world is through the microphone in his cell, though he never knows if anyone hears his pleas for help. The music is constant expression of his environment and friendly responds directly to the performer's gestures. This volume contains the dissertation text.

This study explores general stylistic characteristics of a sample of frequently performed works for solo tuba with prepared tape. Preliminary material includes a brief overview of the status of electronic music in the solo tuba repertoire as well as a short survey of the development of electronic music.
