Acts of Survival: the Plight and Prospects of Dallas Theatre

Description: A comprehensive investigation examines the decline and changes that have affected Dallas regional theatre development from the dream of Margo Jones in the 1940s to the proliferation of emerging theatres in 1993. Changing economic conditions, lack of audience support, and shortages of performance space have contributed to an exodus of Dallas actors and artists. Reviewed are measures to reverse this trend, including funding changes, awareness campaigns, improved inter-theatre cooperation, and guidelines for audience development. The study's conclusion notes that theatres do, indeed, have a natural life cycle, but with renewed emphasis on audience development and self-sufficiency, theatres in Dallas can endure and contribute to an enlarged sense of civic pride.

Seasonality of Birth in Schizophrenia in Taiwan

Description: The phenomenon of seasonality of birth in schizophrenia is important in the study of the etiology of this mental disorder because it helps to give directions for further research. Patients' hospital files from 1981 to 1991 of two of the largest hospitals with psychiatric wards in Taiwan were reviewed, and dates of birth collected on 3346 patients diagnosed with schizophrenia. After adjusting for the variations of the total monthly births in the population, an Auto-Regressive Integrated Moving Average (ARIMA) model was applied. Results support a seasonality phenomenon and indicate a disproportional excess of births in schizophrenia in the cold months (Nov. to Feb.) compared to the hot months (May to Aug.). These findings are compatible with many other studies in other countries and climates. Further investigations of season-related environmental factors in the etiology of schizophrenia are recommended.

Women Becoming: a Feminist Critical Analysis of Mother-Daughter Relationships in Amy Tan's "The Joy Luck Club" and "The Kitchen God's Wife"

Description: This analysis of Tan's first two novels reveals that her female characters suffer from the strains critics like Amy Ling say result from the double paradox of filling the roles of mother or daughter as minority women in a white, male society. Recognizing this double paradox offers Tan's characters, and her readers, the opportunity to resolve the conflicts between mothers and daughters in The Joy Luck Club. Using the theories of psychologist Kathie Carlson helps readers understand how the protagonist of The Kitchen God's Wife resolves similar conflicts with her daughter and her own mother by seeking support from a mythic mother-figure, a Goddess of her own making.

Kinetic Studies of the Reactions of Cl and Br with Silane and Trimethylsilane

Description: The temperature dependence of the reactions of halogen atoms Cl and Br with SiH4 and (CH3)3SiH have been investigated with the flash photolysis-resonance fluorescence technique. CCI4 and CH2Br2 were used as precursors to produce Cl and Br atoms, respectively. Experiments gave {k(Cl + SiH4) (295 - 472 K)} = (1.56 +0.11) x 10-1 exp[(2.0 + 0.2) kJ mol'/RT] cm3 s4, {k(Br + SiH4)(295 - 575 K)} = (9.0 + 1.5) x 10-" exp[-(17.0 + 0.6) Id mol'/RT] cm3 s', {k(Cl + (CH3)3SiH)(295 - 468 K)} = (1.24 0.35) x 104 exp[(1.3 + 0.8) Id mol4/RT] cm3 s', and {k(Br + (CH3)3SiH)(295 - 456 K)} = (7.6 + 3.3) x 1010 exp[-(28.4 + 1.3) Id mol'/RT] cm3 s'. The results were compared with values from earlier work.

Cardiovascular and Hormonal Responses to Orthostasis Following Four Hours of Head-Down Rest in Endurance-Exercise-Trained and Untrained Subjects

Description: Cardiovascular and hormonal responses to +700 head-up tilt (HUT: orthostatic challenge) were compared between six endurance exercise trained (ET) and six untrained (UT) subjects prior to and immediately following 4 hours of -60 head-down rest (HDR). The ET subjects showed a significant (P < 0.05) decrease in orthostatic tolerance time (pre syncopal symptoms) during post-HDR HUT, while no difference was observed between ET and UT groups in pre-HDR HUT. The volume regulatory hormonal responses were similar between ET and UT groups whether during HUT or HDR. The pre-syncopal subjects had a greater increase in plasma arginine vasopressin and less increase in plasma renin activity and plasma aldosterone during HUT than was observed in non syncopal subjects. These data suggest that HDR deconditioning was more effective in the ET subjects.

Albert Speer at Nuremberg

Description: This thesis examines Albert Speer, minister of armaments in Germany during World War II, and the charges against him during the trial of the major war criminals in Nuremberg, Germany, 1945-1946. This thesis portrays Albert Speer as a good man enticed by the power of his position and subsequently playing a role in the crimes of the Third Reich. Primary sources included the Nuremberg Trial proceedings published by the International Military Tribunal and Speer's books, Inside the Third Reich; Spandau: The Secret Diaries; and Infiltration. The thesis has six chapters: preface, biography, the charges against Speer, the verdict, the aftermath concerning his time in Spandau Prison, and a conclusion. Albert Speer accepted his guilt, yet came to resent his imprisonment and questioned the validity of the trial.

Roads for Texas: Creation of a State Highway Department

Description: The work traces the early history of the Texas State Department of Highways. Beginning with the first efforts to create a department, the study focuses on the period between 1917 and 1923. Much attention goes to the legislative background of the early actions of the department. Subsequently, the work examines various statistical measures of the department's performance. This includes comparisons between Texas and nearby states, and the national highs, lows, and averages. Concluding the study is an examination of the department's immediate goals and long range plans in the years after 1923. The general conclusion of the study is that the department played a useful role in the development of state roads in Texas.

Mark Di Suvero's Sculpture: From the Found-Object Sculpture of the Nineteen Sixties to the Monumental Sculpture of the Nineteen Eighties, A Study in Continuity

Description: This thesis analyzes technical and stylistic aspects of Mark di Suvero's nineteen sixties found-object works, and his monumental I-beam sculptures of the nineteen seventies and eighties to demonstrate their consistency despite the apparent contrasts in form, materials, and process. Primary data, sculpture of Mark di Suvero. Secondary data obtained from major art periodicals, newspapers, and exhibition catalogs. The artist was interviewed by author at the retrospective exhibition in Nice, France, Septermber, 17, 1991. Examination of primary and secondary data reveals a strong continuity by the artist in his approach to his work despite obvious external changes in materials and process.

Evidence for the Interaction of GTP with Rat Liver Glyoxalase II

Description: Glyoxalase 11, the second enzyme of the glyoxalase system, hydrolyzes S-D-lactoylglutathione (SLG) to regenerate glutathione (GSH) and liberate free D-lactate. It was found that GTP binds with Gil from rat liver and inhibits Gil activity. Preincubation experiments showed that the binding is relatively tight, since more than 15 minutes are required to release GTP from the complex following dilution. Inhibition kinetics studies indicate that GTP is a "partially competitive inhibitor"; Thus, it would appear that the binding sites for substrate (SLG) and inhibitor (GTP) are different, but spatially close. Glyoxalase 11 binds to a GTP affinity medium, and with polyacrylamide gel electrophoresis, Gil has a higher relative mobility when GTP is present (ATP has no effect). The functional consequences of GTP binding with a specific site on Gil are still unclear. It is speculated that Gil may interact with tubulin by serving as a dissociable GTP carrier, delivering GTP to the tubulinGTP binding site, and thus facilitating tubulin polymerization.

The Torus Does Not Have a Hyperbolic Structure

Description: Several basic topics from Algebraic Topology, including fundamental group and universal covering space are shown. The hyperbolic plane is defined, including its metric and show what the "straight" lines are in the plane and what the isometries are on the plane. A hyperbolic surface is defined, and shows that the two hole torus is a hyperbolic surface, the hyperbolic plane is a universal cover for any hyperbolic surface, and the quotient space of the universal cover of a surface to the group of automorphisms on the covering space is equivalent to the original surface.
