The History of Underground Communication in Russia Since the Seventeenth Century
The purposes of this study were (1) to identify the reasons for and the processes of underground communication in Russia since the seventeenth century and (2) to utilize the information to interpret the clandestine media's significance. The study concluded: (1) underground media have evolved because Russian governments have oppressed free speech; (2) dissidents have shared similarities in the methods of illicit communications; (3) whereas the earlier clandestine press tended to be either literary or political, today's samizdat is a synthesis of many varieties of dissent; (4) underground media have reflected the unique characteristics of Russian journalism; and (5) the Chronicle of Current Events is unparalleled as a news journal in the history of Russian dissent.

The Role of Simulation in the Teaching of Interpersonal Communication: a Descriptive Case Study
This investigation opened with justification of the association of simulation and rhetoric found in the works of Bitzer, Bryant, Burke, and Nichols. It then focused on some advantages that association provides in the classroom: provides learning experiences for diverse groups, applies to problem solving, gives variety to lecture approach, develops social behavior, and increases awareness of alternatives. A list of simulation procedures was provided for specific rhetorical principles: cooperation/competition; decision making; reasoning; recall; perspective; negotiation; and goal setting. Existing, modified, and original games were included. Simulation with a college Interpersonal Communication class provided two case studies. Procedures, results, and evaluative feedback described degrees of effectiveness, and future application and research were also provided.

A Comparison of the Company Magazine and the Grapevine as Selected Communication Channels at the Southland Corporation
This thesis set out to evaluate and compare two communism cation channels at Southland, the company magazine and the grapevine. Data were obtained through a survey in the Summer, 1975, magazine. Following an introduction, explanation of data-collection procedure of the survey, overview of communication in formal and informal organizations, and analysis of the survey data, conclusions were drawn that the magazine is an effective formal communication tool, but that it cannot serve all the formal communication needs of the company, and that expansion of the company's formal communication program is needed. Even so, the formal communication tool, The Southland Family, remains a more effective channel of.communication than the grapevine.

A Comparative Study of Communication Skills in Technical-Vocational and College Parallel Students
This study is an investigation of: the communication skill proficiency of two-year technical-vocational students; the effects of age, ethnic background, and socio-economic index on standardized reading and writing test performance; and of communication skill priorities with respect to content emphasis as perceived by technical-vocational teaching personnel within the Tarrant County Community College system. The purpose of this study is to provide information pertinent to; the development of a functional communication skills program which will complement the occupational student's trade skills; the further development of a pre-technical program currently in operation at Tarrant County Junior College; and the construction of similar programs in other community college systems. This study concludes that the research evidence warrants unique support curriculum programs designed to provide compensatory work and specific training for terminal students in general academic skill areas such as communications.

Toward a Phenomenological Theory of Literature
The problem is the investigation of the possibility of an alternative theory of literature that attempts to show literature's relation to human consciousness. A phenomenological theory of literature is presented as a comprehensive theory of literature as opposed to extrinsic theories that are not comprehensive. The basic assumption is that a comprehensive theory of literature must take into account literature's relationship to human consciousness. The shortcomings of traditional modes of literary theory are discussed in order to provide grounds for the proposed intrinsic alternative. The philosophical foundations for the proposed alternative are laid in the phenomenology of Husserl, Ingarden, Heidegger, and the French existentialists. These four positions are mediated through the introduction of the philosophy of Paul Ricoeur. Finally, the proposed alternative theory of literature is applied to the test case of Joseph Conrad's Lord Jim.

Theory of radiation induced defect production
The theory of defect production in solids by neutron irradiation is reviewed, including discussions of the nuclear reactions which produce the primary recoils and the loss of energy from the displacement cascade by electron excitations. The theoretical predictions are compared with the limited available experiments on thermal and fast neutron irradiation. The results are in rough agreement in most instances, but further improvements in the theory are clearly needed. (auth)

Transmissivity iterative calculation routine: theory and numerical implementation
A computer routine, the Transmissivity Iterative Routine (TIR), has been developed for calculating the hydraulic conductivity distribution in highly heterogeneous aquifers where characterization by field measurement methods alone would be prohibitive in cost. The routine yields the two-dimensional distribution of hydraulic conductivity averaged over the aquifer thickness. The agreement between the calculated and actual average conductivity is dependent on the degree to which the groundwater system satisfies the Dupuit assumption. The program was written for an interactive computer system with a light-pen, CRT display and graphical digitizer, which allow rapid reinterpretation and evaluation of groundwater contours. Testing of the computer program on a synthetic surface identified a set of control parameters that resulted in a maximum computational error of +-5 percent. This maximum error occurred as streamtubes passed near stagnation points where the groundwater hydraulic potential gradients and radii of curvature were small. Sensitivity tests on the Hanford unconfined aquifer indicated that the hydraulic conductivity calculation is not particularly sensitive to errors in the storage coefficient distribution over much of the aquifer. These tests also illustrated the power of the TIR method to evaluate the validity of field data.

Geometrical theory of nonlinear phase distortion of intense laser beams
Phase distortion arising from whole beam self-focusing of intense laser pulses with arbitrary spatial profiles is treated in the limit of geometrical optics. The constant shape approximation is used to obtain the phase and angular distribution of the geometrical rays in the near field. Conditions for the validity of this approximation are discussed. Geometrical focusing of the aberrated beam is treated for the special case of a beam with axial symmetry. Equations are derived that show both the shift of the focus and the distortion of the intensity distribution that are caused by the nonlinear index of refraction of the optical medium. An illustrative example treats the case of beam distortion in a Nd:Glass amplifier.

Determination of Fluid-Induced Loads From Strain Gages: Theory, Equations, and Error Analysis
Strain gages are to be used on the LOFT piping to determine load resultants during the subcooled portion of blowdown in Loss-of-Coolant Experiments. This report discusses the configuration of strain gages to be installed. The selected configuration is shown to: be sufficient to determine the desired load resultants; provide for measurement redundancy; and provide an evaluation of the applicability of the analytical assumptions made in obtaining load resultants from the measured strains. Data reduction equations are derived and an error analysis is performed. Data obtained from an analytical model of a Loss-of-Coolant Experiment is analyzed, showing that the error bounds on the load resultants are less than 12 percent of the load, provided the analytical assumptions are not violated.

The Role of the Peasant Masses in Marxian Political Theory and Practice: a Comparison of Classical and Indian Marxian Views
The central thesis is classical Marxian views concerning the peasant masses have been adopted regarding India; two causal factors are the Hindu Caste system and parliamentary democracy. Descriptive and analytical methodology is utilized to study classical and Indian Marxian theory and its relationship to "Marxist" practice in India. Four major elements involved are: wealthy landowners, poor and landless peasants, the Indian government, and Indian communists. Nonimplemented land reforms and recent capitalist farming compounded the problem. Attacks were launched on the Congress government by three communist parties. Government coalition has included the CPI, and has implemented agrarian reforms advocated by the CPI(M), thereby postponing possible militant communist success.

A Comparison of the Effects of Highly Structured, Partially Structured, and Non-Structured Human Relations Training for Married Couples on the Dependent Variables of Communication, Marital Adjustment, and Personal Adjustment
This study compared the effects of three treatment approaches to training married couples in communication skills on the dependent variables of marital communication, marital adjustment, and the personality characteristics of extraversion/introversion and stability/instability. The initial focus of the study was to determine whether any of the treatment programs--a highly structured (T3), a partially structured (T1 ) or a non-structured (T 2) program -- were superior to any other or to the control group in affecting change in the participants level of communication or in their marital or personal adjustment. The structured programs were derived from the human relations training programs of Carkhuff as well as Rappaport and Harrell's Behavior Exchange Model of conjoint marriage counseling, and adapted for use in a short-term group training procedure. The unstructured training utilized the client-centered approach to couple counseling as developed by Rogers. The number of activities and amount of time spent on each exercise was more rigidly set in the highly structured training than in the partially structured approach. The twenty-four training programs were conducted by two doctoral students in counseling over a seven-week period. A pretest/ post-test, control group experimental design was employed in the research; the data were analyzed using the …

VENTURE: a code block for solving multigroup neutronics problems applying the finite-difference diffusion-theory approximation to neutron transport
The computer code block VENTURE, designed to solve multigroup neutronics problems with application of the finite-difference diffusion-theory approximation to neutron transport (or alternatively simple P$sub 1$) in up to three- dimensional geometry is described. A variety of types of problems may be solved: the usual eigenvalue problem, a direct criticality search on the buckling, on a reciprocal velocity absorber (prompt mode), or on nuclide concentrations, or an indirect criticality search on nuclide concentrations, or on dimensions. First- order perturbation analysis capability is available at the macroscopic cross section level. (auth)

Continuum Theory of Ductile Rupture by Void Nucleation and Growth. Part I. Yield Criteria and Flow Rules for Porous Ductile Media
Widely used constitutive laws for engineering materials assume plastic incompressibility and no effect on yield of the hydrostatic component of stress. However, void nucleation and growth (and thus bulk dilatancy) are commonly observed in some processes which are characterized by large local plastic flow, such as ductile fracture. The purpose of this work is to develop approximate yield criteria and flow rules for porous (dilatant) ductile materials, showing the role of hydrostatic stress in plastic yield and void growth. Other elements of a constitutive theory for porous ductile materials, such as void nucleation, plastic flow and hardening behavior, and a criterion for ductile fracture will be discussed in Part II. The yield criteria are approximated through an upper bound approach. Simplified physical models for ductile porous materials (aggregates of voids and ductile matrix) are employed, with the matrix material idealized as rigid-perfectly plastic and obeying the von Mises yield criterion. Velocity fields are developed for the matrix which conform to the macroscopic flow behavior of the bulk material. Using a distribution of macroscopic flow fields and working through a dissipation integral, upper bounds to the macroscopic stress fields required for yield are calculated. Their locus in stress space forms the …

Interpretation of Inelastic Hadron-Nucleus Collisions
In the interaction of high energy ({approx}> 100 GeV) hadron with a nucleus, there are several interesting points which are not fully explained by the existing models. Firstly, the cross section does not obey the simple A{sup 2/3}-rule. Increase of multiplicities with A is rather slower than expect3ed. Some models are proposed to explain this point. Angular distributions are also to be explained. Here they propose two models which seem to explain various experimental results fairly well. The cross section does not depend on the type of intranuclear interactions.

Application of generalized classical trajectories in nuclear physics
A new semi-classical method, the so-called uniform semiclassical approximation, is described briefly and then applied to two nuclear physics problems. The basic features of this method are that the dynamics of the problem is treated completely classically (that is, one solves classical equations of motion), but the quantum mechanical superposition principle is retained by evaluating a phase along the classical trajectory and adding probability amplitudes for indistinguishable processes rather than probabilities themselves. The first problem considered is the backscattering from a deformed nucleus and the excitation of rotational states in the target at energies up to the Coulomb barrier. The multiple Coulomb excitation calculations are in quantitative agreement with a very different method (the de Boer-Winther code). A nuclear optical potential is also considered and the nuclear-Coulomb interference for heavy ions is studied. The second problem considered is the tunneling through a two-dimensional barrier. This problem (which is supposed to simulate the penetration through a two-dimensional fission barrier) is investigated by a fully quantum-mechanical coupled-channel calculation and by the uniform semiclassical approximation. A quantitative agreement is found. (auth)

The Ratio rho (p p ---> pi0 X) / rho (pi+ p ---> pi0 X) at Large Momentum Transfer and Quark - Quark Scattering
The authors present a phenomenological 'first look' at new Fermilab inclusive data on large p{sub {perpendicular}}{pi}{sup 0} production in pp and {pi}{sup +}p collisions at {theta}{sub cm} {approx} 90{sup o}. Predictions are made using a simple model in which particles are produced at large transverse momentum by a single, hard, large-angle scattering between quarks (q + q {yields} q + q). In this model the ratio R = {sigma}(pp {yields} {pi}{sup 0}X)/{sigma}({pi}{sup +}p {yields} {pi}{sup 0}X) is determined by the difference in the structure functions of the incident proton or pion. This interpretation is consistent with the new {theta}{sub cm} = 90{sup o} data and suggests the importance of measuring R at other {theta}{sub cm} values.

Finite difference solution of the time dependent neutron group diffusion equations
In this thesis two unrelated topics of reactor physics are examined: the prompt jump approximation and alternating direction checkerboard methods. In the prompt jump approximation it is assumed that the prompt and delayed neutrons in a nuclear reactor may be described mathematically as being instantaneously in equilibrium with each other. This approximation is applied to the spatially dependent neutron diffusion theory reactor kinetics model. Alternating direction checkerboard methods are a family of finite difference alternating direction methods which may be used to solve the multigroup, multidimension, time-dependent neutron diffusion equations. The reactor mesh grid is not swept line by line or point by point as in implicit or explicit alternating direction methods; instead, the reactor mesh grid may be thought of as a checkerboard in which all the ''red squares'' and '' black squares'' are treated successively. Two members of this family of methods, the ADC and NSADC methods, are at least as good as other alternating direction methods. It has been found that the accuracy of implicit and explicit alternating direction methods can be greatly improved by the application of an exponential transformation. This transformation is incompatible with checkerboard methods. Therefore, a new formulation of the exponential transformation has …

Consistency among differential nuclear data and integral observations: the ALVIN code for data adjustment, for sensitivity calculations, and for identification of inconsistent data
Successful nuclear design requires adequate prediction of integral design parameters, and this in turn requires an adequate differential nuclear data base. Data bases that apparently permit reduced biases and design margins have been developed by a) least squares adjustment of differential data or b) trial-and-error selection from alternative evaluated data sets. Criticisms and defenses of such procedures are discussed. Useful data adjustment is related to consistency of the combined differential-integral data set and consistency tests related to least squares adjustment procedures are described. An approach to data adjustment is suggested that is contingent on consistency analysis. A FORTRAN code ALVIN has been developed to carry out the indicated data consistency and adjustment calculations, and to compute required sensitivities of integral parameters to nuclear data changes. The sensitivity modules of ALVIN are validated by computing with two distinct methods the cross-section sensitivity profile for neutron penetration through a thick iron shield. The data consistency and adjustment modules DAFT2 (for arbitrary variance-covariance data) and DAFT3 (for differential data base of arbitrary size uncorrelated with integral data) are validated by comparing their results for a set of data for three ZPR criticals. 2 figures, 5 tables, 51 references (auth)
