An Inquiry into Selected Communication Problems Inherent in Financial Statement Certification and Investor/Creditor Response in Light of the Recommendations of the Commission on Auditors' Responsibilities
Business organizations disclose financial Information to a wide range of audiences through the medium of audited financial statements. Distinct classes of readers come in contact with these statements—each reader possessing varying degrees of financial expertise. Readers as "semantic reactors" develop their own expectations and interpretations of the messages management and the auditor are attempting to convey. In the process, many readers look upon the auditor's report as a "symbol" or seal of approval. The purposes of this study were to assess the role that communication theory plays In the auditor's attestation, to examine the perceived communication effects of the expanded auditor's certificate versus the current auditor's certificate, and to recommend ways in which communication problems can be dealt with more effectively. It was concluded that a communication problem does exist in relation to the auditor's report, and communication theory can play a distinctive role in reducing the magnitude of this problem. The profession should continue to seek answers as to the proper role of the auditor and management in relation to audited financial statements, as well as to settle the question concerning whom the statements are intended to serve.

Kindergarten Children and Their Concepts About Print: A Developmental Study Based on Bloom's Theory of School Learning
This study describes the developmental movement of kindergarten children from oral language toward written communication. The study describes and documents evidence of a sample of kindergarten children as they interact with print concepts in a kindergarten environment. The subjects were thirty kindergarten students randomly selected from three specific kindergartens identified as implementing the Key Vocabulary approach of Sylvia Ashton-Warner. The classrooms were public school kindergartens located in a suburban area of North Central Texas. From the findings several conclusions can be drawn. The learning of kindergarten children can be documented and a profile of that learning can be developed that will have possible future use in the learning career of the child. Kindergarten children may perceive the reading of a story to the group differently from the teacher. The perception of the process of writing by kindergarten children may be different from that of adults. There was evidence of children's writing in their movement from oral language toward print.

New methods in nuclear reaction theory
Standard nuclear reaction methods are limited to treating problems that generalize two-body scattering. These are problems with only one continuous (vector) degree of freedom (CDOF). The difficulty in extending these methods to cases with two or more CDOFs is not just the additional numerical complexity: the mathematical problem is usually not well-posed. It is hard to guarantee that the proper boundary conditions (BCs) are satisfied. Since this is not generally known, the discussion is begun by considering the physics of this problem in the context of coupled-channel calculations. In practice, the difficulties are usually swept under the rug by the use of a highly developed phenomenology (or worse, by the failure to test a calculation for convergence). This approach limits the kind of reactions that can be handled to ones occurring on the surface of where a second CDOF can be treated perturbatively. In the past twenty years, the work of Faddeev, the quantum three-body problem has been solved. Many techniques (and codes) are now available for solving problems with two CDOFs. A method for using these techniques in the nuclear N-body problem is presented. A set of well-posed (connected kernal) equations for physical scattering operators is taken. Then it …

The Effect on Marital Adjustment of Teaching Basic Marital Communication in a Conjoint Couples' Group Using Videotape Feedback
The purposes of this study were (1) to determine the immediate effects, if any, on marital adjustment of a marital enrichment program entitled Marital Skills Training. Program (MSTP); (2) to determine the residual effects, if any, on marital adjustment after MSTP had been terminated; and (3) to determine the differences, if any, in the effect on marital adjustment of an on-going group and extended session group using MSTP. Measures of marital communication and marital adjustment served as the dependent variables while the MSTP training served as the independent variable. Instruments used for data collection were the Marital Adjustment Test (Short Form), the Primary Communication Inventory, and the Semantic Differential. The study concluded that teaching marital communication skills in a conjoint couples' group in an on-going setting is an effective way to increase marital adjustment. However, the passage of time appears to be a necessary factor in integrating MSTP into behaviors which affect marital adjustment since the significant increase did not appear until five weeks following training and was found to exist only in the On-going training group.

Compact torus theory: MHD equilibrium and stability
Field reversed theta pinches have demonstrated the production and confinement of compact toroidal configurations with surprisingly good MHD stability. In these observations, the plasma is either lost by diffusion or by the loss of the applied field or is disrupted by an n = 2 (where n is the toroidal mode number) rotating instability only after 30 to 100 MHD times, when the configuration begins to rotate rigidly above a critical speed. These experiments have led one to investigate the equilibrium, stability, and rotation of a very elongated, toroidally axisymmetric configuration with no toroidal field. Many of the above observations are explained by recent results of these investigations which are summarized.

Perturbation and sensitivity theory for reactor burnup analysis
Perturbation theory is developed for the nonlinear burnup equations describing the time-dependent behavior of the neutron and nuclide fields in a reactor core. General aspects of adjoint equations for nonlinear systems are first discussed and then various approximations to the burnup equations are rigorously derived and their areas for application presented. In particular, the concept of coupled neutron/nuclide fields (in which perturbations in either the neutron or nuclide field are allowed to influence the behavior of the other field) is contrasted to the uncoupled approximation ( in which the fields may be perturbed independently).

Recent developments in electron degradation theory: selected topics
The electron degradation spectrum, essentially an energy distribution function of an irradiated system, provides a general basis for determining, not only the fate of the incident (or internally produced) radiation, but also for determining the initial or primary yields of the various excited states of the medium. The degradation spectrum thus describes the initial response of the medium to the radiation. This review-type paper focuses on results obtained in calculations for molecular hydrogen gas. The treatment is presented under the following headings: bookkeeping methods; definition of the degradation spectrum; collision data; water vapor; the total ionization cross section; modification of Gerhart's data; sensitivity of the computed degradation spectrum and mean energy per ion pair; initial yields in H/sub 2/; spectra of sub-excitation electrons; and spatial distributions. 70 references, 3 figures, 2 tables.

Inclusion of mobile helium in a rate theory model of void swelling
The effect of mobile helium on swelling has been studied by using a rate theory model of void growth. The partitioning of mobile helium to various internal sinks and the trapping of interstitial helium atoms by vacancies were included in the model. Helium gas generated during neutron irradiation increases swelling at temperatures above the peak void swelling temperature. Two temperature regimes of enhanced swelling are related to gas-assisted void growth and gas-driven bubble growth. Swelling due to void and bubble growth in a fusion reactor first wall is predicted using nickel as an example, and the effects of dislocation density and grain size on swelling are discussed. It is found that, as compared to simultaneous helium injection during heavy-ion bombardment, the method of helium preinjection is inadequate in simulating a fusion reactor condition.

Application of generalized perturbation theory to fast reactor safety sensitivity studies
A new sensitivity analysis method based on generalized perturbation theory is applied to a typical fast reactor safety code. The adjoint equations are provided for the coupled, nonlinear, conduction--convection equations as they are implemented in MELT-IIIA. An expression for the sensitivity of any temperature to problem input data is presented. In this initial application of the new methodology, two simple transient problems for the Fast Flux Test Facility are considered. Sensitivity results for various temperature responses to all thermal input data are presented. Conclusions are drawn about the practicality and advantages of developing this new sensitivity methodology. Comparisons of perturbation theory with response surface methodologies are also made throughout the paper.

Stability of cable-in-conduit, force-cooled conductors: elementary theory
The recovery of cable-in-conduit conductors cooled by supercritical helium has been studied. The initial perturbation is a sudden, uniform deposition of heat. The problem has been solved, and answers have been obtained in the form of simple closed formulas under the simplifying assumption of constant thermophysical properties. Stability-optimized conductors have been identified and simple formulas for their material composition are given. A rule of design of cable-in-conduit conductors based on the existence of stability-optimized conductors is suggested. Some ''zero-flow'' experiments of Miller et al. have been analyzed, and it has been determined that for these experiments the effective heat transfer coefficient during the period of recovery is approximately 1000 Wm/sup -2/K/sup -1/.

Statistical mechanics and field theory. [Path integrals, lattices, pseudofree vertex model]
Field theory methods are applied to statistical mechanics. Statistical systems are related to fermionic-like field theories through a path integral representation. Considered are the Ising model, the free-fermion model, and close-packed dimer problems on various lattices. Graphical calculational techniques are developed. They are powerful and yield a simple procedure to compute the vacuum expectation value of an arbitrary product of Ising spin variables. From a field theorist's point of view, this is the simplest most logical derivation of the Ising model partition function and correlation functions. This work promises to open a new area of physics research when the methods are used to approximate unsolved problems. By the above methods a new model named the 128 pseudo-free vertex model is solved. Statistical mechanics intuition is applied to field theories. It is shown that certain relativistic field theories are equivalent to classical interacting gases. Using this analogy many results are obtained, particularly for the Sine-Gordon field theory. Quark confinement is considered. Although not a proof of confinement, a logical, esthetic, and simple picture is presented of how confinement works. A key ingredient is the insight gained by using an analog statistical system consisting of a gas of macromolecules. This analogy allows …

Algorithms and computer codes for atomic and molecular quantum scattering theory. Volume I
The goals of this workshop are to identify which of the existing computer codes for solving the coupled equations of quantum molecular scattering theory perform most efficiently on a variety of test problems, and to make tested versions of those codes available to the chemistry community through the NRCC software library. To this end, many of the most active developers and users of these codes have been invited to discuss the methods and to solve a set of test problems using the LBL computers. The first volume of this workshop report is a collection of the manuscripts of the talks that were presented at the first meeting held at the Argonne National Laboratory, Argonne, Illinois June 25-27, 1979. It is hoped that this will serve as an up-to-date reference to the most popular methods with their latest refinements and implementations.

Economic sensitivity study of UCG based on field performance, theory, and operational experience
This paper provides the results of an economic analysis in which uncertainty has been minimized through the use of the following three types of information: (1) theoretical and experimental correlations of underground coal gasification (UCG) operating parameters; (2) detailed process design based on operational experience; and (3) sensitivity variables. Independent variables cannot be fixed with certainty - for example, gas heating values are known for short-term field tests but remain uncertain for a long-term commercial operation. Such variables are designated sensitivity variables and are over their entire probable range. Other sensitivity variables are percent gas loss, well spacing, and the volumetric combustion sweep efficiency (VCSE). Depth and thickness of the coal seam are also designated sensitivity variables because they are strictly site-specific. A total of 1,296 cases have been considered in order to cover a full range of all sensitivity variables. Only-dirty gas selling prices are calculated in order to avoid assumptions concerning unproven methods of gas cleanup. Results show that the seam depth/thickness ratio is the most important variable affecting the economics of UCG. Low BTU gas from a thick coal seam of moderate depth (30 ft. seam at 600 ft.) can compete with current natural gas prices on …

Multiple scattering theory and applications for intermediate energy reactions of nuclei. [50 to 1050 MeV]
Interactions of two composite clusters are treated in a multiple scattering framework whereby many-particle operators are decomposed into a systematic and finite series such that there is an ordered sequestering according to particle rank. Thus, an N-body operator is written as the superposition of all distinct groupings of interactions that occur between particle pairs, triplets, quartets, etc., such that all groupings contain at least one particle from each of the composite systems. It is demonstrated how the transition operator, a reaction operator, and an optical potential may be described in this context. The general structure of such decompositions is shown, and the connection to the standard multiple-scattering prescriptions, delineated. The direct reaction amplitude for stripping and pickup is described, and the two potential formula of Gell-Mann and Goldberger is derived. The multiple scattering formalism for direct reactions is constructed in the eikonal approximation. The sensitivity of the transition cross section to the target density and nucleon-nucleon density correlations are examined in this framework. The limitations of the zero-range approximation to the deuteron vertex function are examined by comparison with the finite-range vertex function at a range of energies. 25 figures, 5 tables.

The Development and Evaluation of a Series of Video-Tape Lessons to Supplement a College Course in Advanced Music Theory
The purpose of the study was to develop and evaluate a series of video-tape lessons to supplement the traditional lecture-discussion method of teaching a college course in advanced music theory. The specific problems investigated were: 1) to evaluate the effect of video-tape material on achievement in an advanced music theory course. 2) To assess the effect of the video-tape materials on the achievement in harmony, keyboard, sight singing, and ear training for students who had differential learning ability levels. 3) To assess the attitudes toward music theory and the use of the supplemental lessons. 4) To assess attitudes toward music theory and the use of the supplemental lessons and achievement for all students involved in the study. Analysis of co-variance, simple analysis of variance, t tests, and Pearson correlations produced statistical results that led to the following conclusions: 1) Students who used the video-tape supplemental lessons did not score higher on achievement tests in harmony, keyboard, sight singing, and ear training than the students who did not use those lessons. 2) Students who used the video-tape lessons had greater variance among the ability levels on the achievement tests; and for those using the lessons, students in the low beginning-ability level …

Single determinantal reaction theory as a Schroedinger analog: the time-dependent S-matrix Hartree-Fock method
It is suggested that the TDHF method be viewed, not as an approximation to but as a model of the exact Schroedinger system; that is, as a gedanken many-body experiment whose analysis with digital computers provides data worthy in itself of theoretical study. From such a viewpoint attention is focused on the structural analogies of the TDHF system with the exact theory rather than upon its quantitative equivalence, and the TDHF many-body system is studied as a challenge of its own which, although much simpler than the realistic problem, may still offer complexity enough to educate theorists in the present state of knowledge. In this spirit, the TDHF description of continuum reactions can be restructured from an initial-value problem into a form analogous to the S-matrix version of the Schroedinger theory. The resulting TD-S-HF theory involves only self-consistent single determinantal solutions of the TDHF equations and invokes time averaging to obtain a consistent interpretation of the TDHF analogs of quantities which are constant in the exact theory, such as the S-matrix and the asymptotic reaction channel characteristics. Periodic solutions then play the role of stationary eigenstates in the construction of suitable asymptotic reaction channels. If these periodic channel states occur …

Neutron cross section calculations for fission-product nuclei. [0. 001 to 20 MeV, Hauser-Feshbach theory]
To satisfy nuclear data requirements for fission-product nuclei, Hauser-Feshbach statistical calculations with preequilibrium corrections for neutron-induced reactions on isotopes of Se, Kr, Sr, Zr, Mo, Sn, Xe, and Ba between 0.001 and 20 MeV. Spherical neutron optical parameters were determined by simultaneous fits to resonance data and total cross sections. Isospin coefficients appearing in the optical potentials were determined through analysis of the behavior of s- and p-wave strengths as a function of mass for a given Z. Gamma-ray strength functions, determined through fits to stable-isotope capture data, were used in the calculation of capture cross sections and gamma-ray competition to particle emission. The resulting (n,..gamma..), (n,n'), (n,2n), and (n,3n) cross sections, the secondary neutron emission spectra, and angular distributions calculated for 19 fission products will be averaged to provide a resulting ENDF-type fission-product neutronics file. 11 references.

An Index of Interpersonal Communicative Competence and Its Relationship to Selected Supervisory Demographics, Self-Actualization and Leader Behavior in Organizations
The purpose of this study was basically twofold: 1) to develop an evaluative instrument to measure interpersonal communicative competence, and 2) to determine its relationship to three other supervisory variables—demographic characteristics, self-actualization, and leader behavior. Hypotheses testing, via the Pearson correlation coefficient, indicated the following relationships between interpersonal communicative competence (as measured by the IICC) and supervisory demographics, self-actualization (as measured by the POI), and leader behavior (as measured by the SBDQ): 1) The age of the supervisor was negatively related to the IICC at the .001 level of statistical significance. 2) Years of formal education was positively related to the IICC at the .001 level. 3) The sex of the supervisor (females scoring higher) was related to the IICC at the .01 level. 4) No significant relationship existed between years of supervisory experience and the IICC. 5) Six scales of the POI (I, Ex, Fr, S, A, C) were related to the IICC at the .001 level of statistical significance, one scale (Sy) at the .01 level and two scales (Tc, Sa) at the .05 level. Three scales (SAV, Sr, Nc) were not significantly related to the IICC. 6) No significant relationship existed between the IICC and the two …
