International competition in services: banking building software know-how--
The international competitiveness of American firms in most manufacturing industries has been in decline, in large part because of growing competence in other parts of the world. As this assessment shows, the United States remains highly competitive in many service industries, But trade in services will remain small compared to trade in goods, and many of the benefits from foreign investments by American service firms accrue to the host nations where U.S.-based banks, insurance companies, accounting firms, and other suppliers of services do business, Services cannot right the Nation’s trade balance, even granting the many ways in which a strongly competitive service sector benefits the competitiveness of American manufacturing firms.

Oblate-prolate shape competition in Z = 34 to 38 nuclei
Now magic numbers for deformed shapes are established at N and Z of 38 and N of 60. These shell gaps at large deformation (..beta.. approx. = 0.4) are magic when the proton and neutron shell gaps reinforce each other. Other shell gaps for 34 and 36 are predicted to be important for oblate deformation. The competition between these oblate and the 38 prolate gaps as well as the 40 spherical shell gap are considered. In /sup 71/Se coexistence of oblate (..beta.. approx. = -0.24) and large prolate (..beta.. approx. = 0.4) shapes are observed. In /sup 72/Se the excited prolate band with large deformation which coexists with the near-spherical ground state is found to dominate the yrast spectrum to 28/sup +/. The moment of inertia of this band is essentially that of a rigid body. This moment of inertia supports the suggestion that the ''super deformation'', ..beta.. approx. = 0.4, being observed in this region may be associated with a collapse of pairing.

Genetic algorithms and classifier systems: Foundations and future directions
Theoretical questions about classifier systems, with rare exceptions, apply equally to other adaptive nonlinear networks (ANNs) such as the connectionist models of cognitive psychology, the immune system, economic systems, ecologies, and genetic systems. This paper discusses pervasive properties of ANNs and the kinds of mathematics relevant to questions about these properties. It discusses relevant functional extensions of the basic classifier system and extensions of the extant mathematical theory. An appendix briefly reviews some of the key theorems about classifier systems. 6 refs.

Analytical and numerical analysis of finite amplitude Rayleigh-Taylor instability
We summarize the results obtained in the last year. These include a simple model of bubble competition in Rayleigh-Taylor unstable flows which gives results which are in good agreement with experiment. In addition the model has been compared with two dimensional numerical simulations of inviscid Rayleigh-Taylor instability using the cloud-in-cell method. These simulations can now be run into the late time regime and can track the competition of as many as ten bubbles. The improvement in performance over previous applications of the cloud-in-cell approach is due to the application of finite difference techniques designed to handle shock-like structures in the vorticity of the interface which occur at late times. We propose to extend the research carried thus far to Rayleigh-Taylor problems in three dimensional and convergent geometries as well as to two-fluid instabilities in which interface roll-up is observed. Finally we present a budget for the fiscal year 1987-1988. 6 refs.

Rumeurs (Place Ransbeck)
Access:
Use of this item is restricted to the UNT Community
A rumor is a sound in the air. Elusive, we seek to capture it, fearing that it may concern us, that it may hold a part of shameful truth. Fleeting, it cannot be caught. As soon as it materializes, it vanishes, leaving only traces in our memories. Here, nothing is certain. Where does this sound come from? What is it made of? The piece endlessly oscillates between pure sound and meaning, without ever resolving to one or the other. The piece is at the limit between texture and image, between material and anecdote. And rumors go by, always surrounding us. Here and there, sounds reach us like faint echoes of the world. If you believe hearing things about you, why worry? After all they're only rumors... and if you listen carefully, you may find the key. ... (Place de Ransbeck) A small square in Ohain (Belgium), home of studio Métamorphoses d'Orphée where the piece was produced in June, 1987.

Campaign Financing
This is one report in the series of reports that discuss the campaign finance practices and related issues. Concerns over financing federal elections have become a seemingly perennial aspect of our political system, centered on the enduring issues of high campaign costs and reliance on interest groups for needed campaign funds. The report talks about the today’s paramount issues such as perceived loopholes in current law and the longstanding issues: overall costs, funding sources, and competition.

Microrreflexiones
Access:
Use of this item is restricted to the UNT Community
The play was performed at GRM studios, Radio France, in 1987. This is an illustration of Paul Eluard's poem "The Phoenix.” The music, produced from the voice of the mezzo-soprano Anne Gilbert, follows the different situations suggested by the poem, in a sort of semantic game where the meaning will be lost and found by producing a narrative musical and episodic form evoking the shape that follows. As its title suggests, the play is made up of small moments that follow each other, while the text frames the overall form of this polysemic diversity. "Microrreflexiones" won the 2nd Prize of Electroacoustic Music at Program of the International Competition of Bourges, 1988.

Third-harmonic generation and multiphoton ionization spectroscopy
Nonlinear phenomena, such as multiphoton excitation (MPE) processes leading to ionization and third-harmonic generation (THG) in gases have become the issue of extensive studies over recent years. Studies in rare gases in particular have resulted in several interesting observations in this respect. Thus, it has been established that three-photon resonantly enhanced multiphoton ionization (MPI) in the vicinity of states which are single photon optically coupled to the ground state may occur in efficient competition with THG. The present work demonstrates several new effects which may appear when third-harmonic radiation is present during MPI.

The effect of fluoride and aluminum on the anion exchange of plutonium from nitric acid
Anion exchange in nitric acid is a prominent aqueous process used to recover and purify plutonium from impure nuclear materials. This process is sensitive to fluoride ion, which complexes plutonium in competition with the anionic nitrato complex that is strongly sorbed on the anion exchange column. Fluoride interference traditionally has been counteracted by adding a masking agent, such as aluminum, that forms competing complexes with fluoride. The interfering effect of fluoride is known to be a function not only of the fluoride-to-aluminum ratio but also of the fluoride-to-plutonium ratio. This report summarizes a Los Alamos study of the effect of 25 fluoride-aluminum-plutonium conmbinations on the anion exchange sorption of plutonium. Five aluminum-to-plutonium ratios ranging from 0.10 to 10 were each evaluated at five fluoride-to-aluminum ratios that ranged from 0 to 6. The fluoride-to-plutonium ratio has a greater influence on plutonium sorption than does the fluoride-to-aluminum ratio. Aluminum was less effective as a masking agent than had been assumed, because measurable fluoride interference occurred at all levels of added aluminum.

Corrosion of ferritic steels by molten lithium: Influence of competing thermal gradient mass transfer and surface product reactions
An Fe-12Cr-1MoVW steel was exposed to thermally convective lithium for 6962 h. Results showed that the weight change profile of Fe-12Cr-1MoVW steel changed substantially as the maximum loop temperature was raised from 500 to 600/sup 0/C. Furthermore, for a particular loop experiment, changes in the structure and composition of the exposed surfaces did not reflect typical thermal gradient mass transfer effects for all elements: the surface concentration of chromium was often a maximum at intermediate temperatures, while nickel (present at low concentrations in the starting material) tended to be transported to the coldest part of the loop. Such data were interpreted in terms of a qualitative model in which there are different dominant reactions or the various constituents of the ferritic steels (surface product formation involving nitrogen and/or carbon and solubility-driven elemental transport). This competition among different reactions is important in evaluating overall corrosion behavior and the effects of temperature. The overall corrosion rate of the 12Cr-1MoVW steel was relatively low when compared to that for austenitic stainless steel exposed under similar conditions.

Thin film microstructures: Simulation and theory
The nature of the microstructure of physical vapor-deposited films depends sensitively on the substrate temperature during deposition. At low temperatures the microstructure is porous and ballistic aggregation-like, at intermediate temperatures the microstructure is columnar, and at elevated temperatures the grains are three dimensional. These different microstructural regimes are known as Zone I, II, and III, respectively. A theoretical analysis is presented in which the temporal evolution of the columnar microstructure (Zone II) is studied. The columnar microstructure is shown to be a balance between shadowing (which results in Zone I microstructures) and surface diffusion (which tends to smooth the surface). In addition to predicting the proper microstructure, this analysis properly predicts the temperature at which the Zone II to Zone I microstructural transition occurs. Since bulk diffusion is negligible and surface diffusion controls the microstructure in Zone II, the microstructure in the bulk of the film, may be viewed as frozen and all microstructural evolution occurs at the current, or active, surface. A Monte Carlo computer simulation technique which models the microstructural evolution of the surface is presented. The simulation follows the temporal evolution of realistic three dimensional Zone II microstructures and accounts for growth competition between adjacent grains and …

Life History Biology of the Desert Nesting Seagull Larus modestus
Gray gulls Larus modestus are unique among birds of northern Chile as the only species nesting in the interior Atacama Desert, and the only seagull nesting far (30 - 100 km) from surface water. During breeding-nesting (August - February) gray gulls congregate on the coast of northern Chile where they feed and initiate courtship. As early as August, breeding pairs commute daily to the inner desert to establish nesting territories, round-trip distances of 60-200 Km. During incubation (30 days) and brooding (7 days) adults alternate daily foraging flights to the coast. Afterwards, both adults forage daily for their chick(s) until fledging (ca. 60 days). Foraging flights and thermoregulatory costs during the period of maximal solar radiation, when ground temperatures may reach 61 C in the day and drop to 2 C at night, have selected for adaptations which minimize those costs: tolerance of hypothermia and hyperthermia; dark plumage; low egg-shell water vapor conductance; low standard metabolic rate; elaborate repertory of thermoregulatory behavior which allow adults to take advantage of microclimatic variations in the desert and minimize costs relative to a sympatric congenor, Larus belcheri scheduling foraging flights to take advantage of optimal atmospheric conditions and presence of forage fish (anchovies) …

Les Morceaux de Concours de Flûte du Conservatoire de Paris: A Structural Comparison of Selected Works of Jean-Louis Tulou and Joseph-Henri Altès: A Lecture Recital Together with Three Recitals of Selected Works of Mozart, Halffter, Gaubert and Others
The lecture was presented April 7, 1987. This presentation centered on the flute music literature used for the Concours of the Conservatoire de Paris from 1828 through 1893. The historical parameter began with Jean-Louis Tulou's tenure as flute professor at the Conservatoire and ended with Joseph-Henri Altes'tenure in the same capacity. The Concours is an annual performance competition to determine which students on each instrument will graduate from the Conservatoire. The majority of Concours pieces for flute during the tenures of professors from Tulou through Altes were composed by those two men. Short biographies of Tulou and Altes were presented. Discussion of interim professors Victor Coche and Vincent-Joseph Dorus was included, with focus on the role of these two men in bringing acceptance of the Boehm system flute to the Conservatoire. Tulou's fifteen Grands Solos were compared in form, key center and tonal progression. His themes and passagework are constructed to best display the conical-bore, old system-flute with small toneholes. His Solos continued to be used for the Concours, in alternation with Altes', throughout the tenures of both Vincent-Joseph Dorus and Altes. Tulou's Cinquieme Grand Solo was used for more detailed analysis and performance. Altes wrote his Solos de Concours …

From the Journals of Felix Bosonnet
Access:
Use of this item is restricted to the UNT Community
The text heard in this piece is the last insert in the journals of the Swiss artist Felix Bosonnet (1943-1985), written shortly before his suicide. It was written in three parts, the third left unfinished. The music simply places the text in a sound setting. The sounds in the first two parts are derived from cowbells recorded in the Swiss Alps. In the third part, one of the sources is a small crystal glass. The piece was composed at the Brooklyn College Center for Computer Music on a DEC PDP-11/44 computer, using Music 11 and the C programming language. "From the Journals of Felix Bosonnet" received an honorary mention at the 16th International Electroacoustic Music Competition and is recorded on the 1989 International Computer Music Conference compact disc. The reader is Christoph Gaugler. I. I cannot claim I know no-one, but nobody knows me. On the other hand, it would seem to me pretentious to describe myself as a man of great trials.

Fuel cells for extraterrestrial and terrestrial applications
The fuel cell is a nineteenth century invention and a twentieth century technology development. Due to the high power and energy density, high efficiency, reliability, and production of pure water, hydrogen-oxygen fuel cell systems have no competition as auxiliary power sources for space vehicles. The alkaline fuel cell system is a well developed and proven technology for this application. The solid polymer electrolyte system may be its future competitor. The energy crisis of 1973 stimulated research, development and demonstration of the phosphoric acid, molten carbonate, solid oxide and solid polymer electrolyte fuel cell systems using natural gas, petroleum or coal derived hydrogen (and carbon monoxide for the high temperature systems) for terrestrial applications. The direct methanol-air fuel cell is still an electrochemist's dream. Though considerable technological advances have been made, the present price of crude oil, and the high capital costs and limited lifetime of fuel cell systems impede their terrestrial applications in the developed countries. Conversely, the potential for lower capital costs of labor intensive manufacturing processes and the relatively higher fossil fuel prices make these systems more attractive for such applications in the developing countries. 11 refs.

Triathlon: an Original Screenplay
A young man, out of college and work, sets out to make his mark on the world, by winning the endurance sport of the eighties: the Hawaiian Ironman Triathlon. As he eats, sleeps and breaths "Ironman," he shuts others out of his life because he feels that he must do it alone for the victory to be genuine; a philosophy that has been dogging him all his life.

Retail Buyers Saleability Judgements: A Comparison of Merchandise Categories
The purpose of this study was to investigate the saleability judgements of retail store buyers of women's and men's wear. A sample of 81 women's and men's wear buyers, representing two specialty stores and one mass merchandiser, was sent questionnaires. Principal Components Factor Analysis with Varimax Rotation was used to reduce the number of product, vendor and information source variables to eight factors. Three significant differences existed between the women's wear and men's wear buyers, verifying that not all retail buyers are alike. Results will benefit educators in preparing students to become more effective buyers, retail management can incorporate this same information into a buyer training program and apparel manufacturers can use the study in planning product strategies to retailers.
