Pulse*Star Inertial Confinement Fusion Reactor: heat transfer loop and balance of plant considerations
A conceptual heat transfer loop and balance of plant design for the Pulse*Star Inertial Confinement Fusion Reactor has been investigated and results are presented. The Pulse*Star reaction vessel, a perforated steel bell jar approximately 11 m in diameter, is immersed in Li/sub 17/Pb/sub 83/ coolant which flows through the perforations and forms a 1.5 m thick plenum of droplets around an 8 m diameter inner chamber. The reactor and associated pumps, piping, and steam generators are contained within a 17 m diameter pool of Li/sub 17/Pb/sub 83/ coolant to minimize structural requirements and occupied space, resulting in reduced cost. Four parallel heat transfer loops with flow rates of 5.5 m/sup 3//s each are necessary to transfer 3300 MWt of power. The steam generator design was optimized by finding the most cost-effective combination of heat exchanger area and pumping power. Power balance calculations based on an improved electrical conversion efficiency revealed a net electrical output of 1260 MWe to the bus bar and a resulting net efficiency of 39%. Suggested balance-of-plant layouts are also presented.

Proceedings of the Workshop on Electronic and Ionic Collision Cross Sections Needed in the Modeling of Radiation Interactions with Matter, Held at Argonne National Laboratory December 6-8, 1983
The term modeling in the Workship title refers to the mathematical analysis of the consequences of many collision processes for characterizing the physical stage of radiation actions. It requires as input some knowledge of collision cross sections. Traditionally, work on cross sections and work on the modeling are conducted by separate groups of scientists. It was the purpose of the Workshop to bring these two groups together in a forum that would promote effective communication. Cross-section workers described the status of their work and told what data were available or trustworthy. Modeling workers told what kind of data were needed or were most important. Twenty-two items from the workshop were prepared separately for the data base.

Comparative Ecology of Benthic Communities in Natural and Regulated Areas of the Flathead and Kootenai Rivers, Montana
A comparative study was made of environmental variables and the density, biomass, diversity, and species composition of macroinvertebrates in areas downstream from a dam with a hypolimnetic release (Hungry Horse Dam on the Flathead River) and a dam with a selective withdrawal system (Libby Dam on the Kootenai River). A major objective of this study was to examine the response of macroinvertebrate communities to defined environmental gradients in temperature, flow, substrate, and food-related variables (periphyton, particulate organic carbon in the seston). In addition, the effects of experimental manipulations in discharge on macroinvertebrate drift and stranding were assessed, and the effects of temperature on the growth rates and emergence of five species of insects were measured.

Sustenance Organization and the Repopulation of Nonadjacent Nonmetropolitan Counties in the State of Texas, 1970-1980
From 1970 to 1980 nonadjacent counties in Texas experienced an increase in net migration of 9.4 percent, significantly different from the 11.8 percent decrease experienced the previous decade. This study utilized the ecological perspective to study this redistribution pattern in Texas' nonadjacent counties between 1970 and 1980. Sustenance organization, defined as sustenance differentiation (the functional organization of sustenance activities and the dispersion of workers across these functional categories) and the mode of sustenance organization (the combinations of various sustenance activities) was identified as the primary independent variable. In addition, three secondary independent variables were included in the analysis (population per square mile, metropolitan dominance, and the percent who work outside the county of residence).

An Analysis of Teacher Perceptions of Inhibitors to Effective Classroom Teaching in Secondary Schools
The primary purpose of this study was to examine the inhibitors affecting classroom teaching by surveying the perceptions of secondary teachers. This purpose was based on the growing crisis of "teacher burnout" which was thoroughly documented. Since it appears that burnout most often affects those teachers who work in conventional classrooms, characteristics of teaching effectiveness within these classrooms were the basis for inhibitor comparison. Seven characteristics were produced by a crosstabulation of studies on effective teaching spanning the last fifty years. The inhibitor choices presented with these seven characteristics were extracted from an extensive list produced by the literature and classified under six areas of origin. The characteristics and inhibitors ultimately selected were surveyed among teachers in a large Southwest metropolitan area.

Genetic and Morphological Variation in Natural Populations of the Red Shiner, Notropis lutrensis, and their Relationship to Adaptation in a Generalist Species
Twenty-two natural populations of the red shiner minnow, Notropis lutrensis were examined for morphological and genetic variation. This research was aimed at testing the hypothesis that morphological and genetic variation was primarily influenced by the degree of gene flow between populations. Ten linear measurements were taken from each of 1320 specimens. Morphological characters were adjusted for differential growth by least squares linear regression techniques. Genetic variability was estimated for each individual red shiner through the methods of starch gel electrophoresis. Twenty presumtive gene loci were resolved.

Entry Level Competencies for Recreational Sports Personnel as Identified by Chairs of Preparatory Institutions
The problem of this study was to determine if the competencies identified by recreational sports practitioners as most needed for entry into the profession were the same as those identified by chairpersons of preparatory departments. Furthermore, this study determined if chairpersons of physical education and recreation curricula identified significantly different competency areas for entry level personnel. The two populations of respondents were from sixty seven institutions listed in the 1982 SPRE-NRPA Curriculum Catalog. Each subject was asked to complete a copy of the Jamieson Recreational Sports Competency Analysis. The criterion scores for each of the statements were divided into twelve competency areas for analysis.

Community in Japanese Political Organization
The most important long-term political forces operative in the Japanese political system are the interplay of decentralized community authority and the consolidation of that authority toward the top. The mura kyodotai (village community) concept is representative of both types of authority, neither of which has defined boundaries. An examination of the nature of indigenous community authority may provide the broad context for a valid understanding of Japanese decision making. Under the ideal of this order, Japanese political organization has valued the structure of Shinto: polytheistic local authority, plus conflated authority of church and state. Buddhism and Confucianism have provided direction and moral force to preserve traditional order.

Raman Studies of Molecular Dynamics and Interactions in Liquids
In order to explore the N-H stretching region of aliphatic amines, we performed a study of the Raman spectrum of n-propylamine at various concentrations in cyclohexane. Statistical analysis provided evidence of a second symmetric stretching vibration, which we were able to assign to nonhydrogen bonded NH2 groups. To obtain additional evidence on the existence of monomers in n-propylamine and to further study hydrogen bonding and Fermi resonance in aliphatic amines, we extended the investigation to the analysis of the Raman spectrum of this compound over an extended range of temperature in the neat liquid phase. This study corroborated our finding that the peak previously assigned to the symmetric stretching mode of hydrogen bonded amines is actually composed of two bands. Furthermore, trends in both the resolved band parameters and the Fermi resonance analysis were tabulated, allowing one to monitor the change in the N-H valence region with concentration and temperature.

Secondary Laboratory Teachers' Student Grouping Decisions: A Descriptive Study
Teachers use student grouping to reduce the complexities of the classroom. Grouping has been credited with making behavior more predictable, improving interpersonal skills, and making instruction easier by increasing homogeneity. Research suggests that teachers' grouping decisions are influenced by characteristics of the student, the teacher, the task, and the environment. Research on grouping has centered on elementary classes, with little investigation of secondary classes. The purpose of this study was to describe the influences on secondary laboratory teachers' grouping decisions in a naturally occurring secondary school setting.

The Objectives of Basic Political Science Courses in Texas Institutions of Higher Education as Perceived by Instructors of the Courses
The State of Texas requires the completion of all six semester hours of government for graduation from a public college, but does not provide detailed guidelines regarding content, and related objectives, for these courses. Thus instructors have considerable discretion in the setting of course objectives. The problem of this dissertation, therefore, is the determination of course objectives actually set and the general orientation within political education that the objectives may reflect.

Post-Traumatic Changes in Perceptions of Purpose in Life and Three Dimensions of Locus of Control in Stroke and Hip Surgery Patients
A survey of stress and crisis literature indicated traumatic events tend to initially overwhelm individual coping resources. The adjustment process following such events appears to be characterized by phases in which gradual perceptual and cognitive reorganization occurs. Emotional shock, denial processes, and intrusive ideation accompany initial phases.
