Selected Factors Associated With Reading Interests of Seventh- and Eighth-grade Pupils
This study sought to determine if there were differences in the types of reading interests of seventh- and eighth-grade pupils associated with their racial origins, their socioeconomic status, or their school environments. It also sought to consider the strength of reading interest scores as related to other variables and to consider the relationship between these scores and the number of hours spent in reading and the change in amount of reading since the previous school year.

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.

The Perceptions of Junior High School Principals, Their Spouses and Their Building Counselors Regarding Occupational Sources of Stress for the Principals
The purpose of this study was to identify the perceptions held by junior high school principals, their spouses, and school counselors regarding occupational stressors of the junior high school principals in the State of Texas. The occupational stressors center around five areas of concern: (1) administrative constraints, (2) administrative responsibilities, (3) interpersonal relations, (4) intrapersonal conflicts, and (5) role expectations. A randomly selected sample of 300 junior high school principals were sent questionnaires for themselves, their spouses, and their school counselors. Descriptive statistical methods were employed to calculate means and standard deviations of the principals', spouses', and counselors' perceptions of the occupational stressors of the principals. T-test and one-way analysis of variance were used to analyze the data.

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.

Picosecond Measurement of Interband Saturation, Intervalence Band Absorption, and Surface Recombination in Germanium
The picosecond optical response of five thin germanium samples was measured following intense optical excitation using two variations of the excitation and probe technique. Seven-picosecond laser pulses of wavelength 1.054 um were used to measure the optical transmission of the samples for a variety of probe delays, excitation fluences, and sample temperatures. These parametric experiments were performed in an effort to determine if carrier cooling, carrier diffusion, or carrier recombination dominates the carrier dynamics immediately following excitation. The studies of a 5.7 um thick sample indicated that Auger recombination does not dominate the carrier dynamics, but that the carriers most likely cool immediately to within a few optical phonons of the lattice temperature. Lattice heating may also occur depending on excitation level. Neither cooling nor diffusion was ruled out as a major contributor to the transient optical response. A numerical analysis indicated that, although diffusion may be minimized in the thinner samples, the importance of surface recombination increases as the sample thickness decreases. The lattice temperature dependence of the optical transmission was found not to be in disagreement with the known temperature dependence of the low-density diffusion coefficient. Finally, new structure was observed in the data which is consistent with …

Environmental Effect: Activator of the Psychotic Process
The purpose of the present study was to determine specific psychotic factors associated with environmental sensitivities, the changes in those tendencies occurring with ecological treatment and the extent to which those behaviors could be attributed to the chronicity of the illness. An inpatient group of 42 environmental patients was compared to an inpatient population of 20 chronic spinal pain patients. Instruments utilized in the study included the Bender Gestalt Test of Motor Ability, the Minnesota Multiphasic Personality Inventory (MMPI) with the Harris and Lingoe subscales, and three subtests of the Wechsler Adult Intelligence Scale-Revised, Digit Symbol, Object Assembly, and Block Design. Data was analyzed via multivariate analysis of covariance, analysis of covariance, canonical analysis, and t tests for related and independent means.

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.

A Guide for the Identification and Research of Victorian Furniture in Six Historic House Museums in Texas
One hundred and seventy-eight pieces of Victorian furniture in six Texas historic house museums have been photographed and researched in order to fulfill the three-part problem. (1) to research and write descriptive essays of the four major Victorian substyles--Victorian Empire, Rococo Revival, Renaissance Revival, and Eastlake; (2) to identify and choose six Texas historic houses which are open to the public and which display these Victorian substyles in period room settings; and (3) to identify, photograph, measure, and catalogue each piece of authentic Victorian furniture, and to compile a research guide which includes each of these six houses and their Victorian furnishings. This six-part guide includes brief histories of each house and a catalogue of authentic pieces which represent the major substyles of Victorian furniture. To give the study a broad base, and to make it useful for all students, teachers, and professional interior designers in Texas, two houses which represented the best collections of furniture from each geographic location were chosen. These included: (1 ) from North Texas, the George House and Millermore, both in Dallas; (2) in Central Texas, East Terrace and Fort House, located in Waco; and (3) in South Texas, Fulton Mansion in Fulton Beach, and …

The Influence of Hypnotically-Induced Elevation of Mood on Learned Helplessness Deficits
This study evaluated the efficacy of hypnoticallyinduced mood elevation techniques for individuals exposed previously to an experimental learned helplessness condition. The treatment conditions in this investigation included the mood elevation with hypnotic induction group as well as a mood elevation group without the benefit of hypnotic induction. As experimental controls, a group was exposed to hypnotic relaxation and an attention-only treatment group was used. Measures of treatment success included the administration of•the Depression Adjective Checklist, backward digit span, and five—letter anagrams. In a series of factorial analysis of variance procedures no significant interaction was noted although the main effect for the presence of hypnotic induction was significant with the Depression Adjective Checklist. Post hoc analysis to examine gender differences demonstrated no significant performance discrepancy between the sexes. Limitations of the study were explored and avenues of further research discussed.

The Effects of Maternal Employment and Family Life Cycle Stage on Women's Psychological Well-Being
The study examined the impact of maternal employment and family life cycle stage on the psychological well-being o£ middle socioeconomic status women. One hundred twenty eight mothers of children at the stages of birth to 6 years, 7 to 12 years and 13 to 17 years, completed a self-report questionnaire. To test the hypothesis of the study, a 3 X 3 (employment X family life cycle stage) analysis of covariance was conducted with age, income, time employed and psychological resources as covariates. Results indicated that middle socioeconomic status mothers employed full-time experienced significantly higher levels of role overload, occupational strain, spouse support and job commitment. A post hoc exploratory analysis using conflict level between commitment to work and parenting, yielded data which indicated that individuals with a large discrepancy between commitment to one role versus the other, experienced the greatest degree of difficulty. Results were evaluated in the light of selective characteristics of the sample. Recommendations for future research included the use of projective assessment to reduce the effect of defensive response styles. A life span approach using the concept of perceived conflict between roles was advanced, instead of the age specific developmental construct of family life cycle stage.

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.

Allocation of Attention: Effects on Classical Conditioning
According to Deikman (1966), meditation (defined as a training to sustain attention) has a deautomatizing effect. This ascertion was utilized in the present study as a departure point and explored within an information processing framework for classical conditioning. A sample of 48 college students was selected and randomly assigned to four conditions with different instructional sets involving allocation of attention during a classical conditioning background situation. The basic hypothesis of the study was that provided arousal factors were controlled, focusing of attention upon internal stimulation (i.e. breathing) could delay or attenuate the affect of conditioning, habituation and extinction as compared with instructions to externally allocate attention (on the CS and US). A secondary hypothesis predicted that for subjects under switching conditions changing from internal to external allocation and vice versa would produce a more pronounced extinction pattern as compared with subjects under non—switching conditions.

Life History Energetics of The Red-Eared Turtle, Pseudemys scripta in North Central Texas
A population of the red-eared slider, Pseudemys scripta, in north central Texas was studied from 1975 to 1980. A life history energy budget was developed for a typical individual in the population and the population dynamics were estimated. A growth model relating growth rate to mean plastron length (PL) was developed from recapture data and used to 1) establish age classes and 2) age individuals. Growth rate was highly variable in both sexes. Females grew more rapidly than males and attained a larger maximum size (230 mm and 195 mm PL in females and males respectively). Females reached sexual maturity in their ninth year at a PL of 185-190 mm. Males matured in their sixth year at a PL of 90-100 mm. Females produced three clutches annually; clutch size ranged from 7 to 14 (X=10.3; N=20). Ova were enlarged in the early spring and ovulation began in late April and early May. Egg laying occurred from mid- May through June. Both egg size and clutch size increased with female body size. Lipid levels were variable within and among seasons. No annual lipid cycling pattern was evident in females. The proportion of assimilated energy devoted to reproduction, a measure of reproductive …
