This study investigated the predictive value of time on-task and error scores on tests administered through Control Data Corporation PLATO interactive computer graphics simulation as predictors of errors and time on-task for inertial navigation system equipment operation. In addition, the correlation between simulated pass/fail error and time on-task scores, and subsequent pass/fail criteria using actual equipment was investigated.

The problem of the investigation was to ascertain the contributions of various sociological theorists to a sociology of emotions. Emphasis was to be placed on the symbolic interactionist school. The method employed was that of a literature review, with an evaluative analysis of each of a number of writers as each contributed to a sociology of emotions. The study had the purpose of remedying the long-standing neglect of emotions by sociologists. This purpose was accomplished by indicating the distinctive contributions of each theorist and areas of convergence among theorists. The investigation was organized according to groups of theorists. Each theorist was examined for conceptions of human nature and of the relationship between the individual and society. Chapter I discussed the problem in general; the remaining chapters analyzed the theorists. Chapter II discussed the classical theorists Emile Durkheim, Max Weber, Georg Simmel, and Talcott Parsons. Chapter III presented the views of the symbolic interactionists George Herbert Mead, Charles Cooley, Herbert Blumer, Hans Gerth and C. Wright Mills, and Erving Goffman. Chapter IV treated contemporary theorists: Arlie Hochschild, Theodore Kemper, Susan Shott, and Norman Denzin.

This study examined the effectiveness of the Human Resource Development model of classroom social skills with intermediate elementary learning disabled children. A pretest posttest control group design was employed. The sample consisted of 40 fourth-, fifth-, and sixth-grade LD pupils who scored in the bottom fourth of their classes in peer acceptance. The subjects were randomly assigned to the treatment or control group. Treatment consisted of six daily one hour training sessions covering the five skills of physically attending, psychologically attending, greeting, making polite requests and complying with requests. Subjects met in groups of six to eight in lieu of learning assistance and were instructed through methods including modeling, demonstration, role playing, didactic instruction, feedback and self-monitoring. The control group received no treatment but went to learning assistance as usual.

The problem with which this study was concerned is an investigation of physics instruction in Texas public secondary schools. The purposes of this study were to investigate the status of physics instruction and to determine the in-service needs and preferences of the physics teachers in Texas public secondary schools. Data were collected by a questionnaire that was sent to a stratified random sample of 100 teachers. The questionnaire was evaluated by a panel of advisors and pilot tested. The bases for stratification were relative school size and geographic location. Usable returns were obtained from 69 respondents.

The comparability of PPVT and PPVT-R scores among retarded adults were examined. The sample consisted of 96 clients, who had been previously diagnosed as mildly, moderately, or severely retarded. The PPVT (Form A) and PPVT-R (Form L) were administered to all participants in counter balanced order. Significant correlations were found between the two tests for the total sample as well as for females and males. Additionally, the PPVT-R was found to be capable of discriminating differing levels or retardation. However, with the exception of the severely retarded group, mean PPVT-R Standard Score Equivalent (SSE) scores tended to be approximately 20 points lower than PPVT IQ scores. Some clinical implications of these results were discussed.

Unlicensed radio stations in 1933 tested the Radio Act of 1927 as to whether or not the Federal Radio Commission (FRC) had the right to regulate radio stations whose signals were allegedly intrastate. The FRC believed it could regulate such radio stations and proceeded to confiscate equipment, charge individuals with violation of the law, and bring them to trial, either in an injunction hearing, a criminal trial, or both. The most formidable case was that of United States v. Gregg et al. The challenge was met by the FRC and the judge, whose decision is still quoted in legal documents. The decision upheld the Radio Act of 1927 and the FRC's right to regulate all radio stations, licensed or unlicensed.

This thesis relates a technique for increasing the optical strength of NaCl and KCl single-crystal samples. The 1.06-μm pulsed laser damage thresholds were increased by factors as large as 4.6 for a bulk NaCl single-crystal sample. The bulk laser damage breakdown threshold (LDBT) of the crystal was measured prior to and after heat treatment at 800*C using a Nd:YAG laser operating at 1.06 μm. Bulk and surface LDBTs were also studied on samples annealed at 400° C. These samples showed differences in damage morphology on both cleaved and polished surfaces, and the cleaved surfaces had improved damage thresholds. However, neither the polished surfaces nor the bulk showed improved threshold at the lower annealing temperature.

This descriptive report is designed to document the development of this conceptual structure. The purpose is to clarify each aspect of the metaphor and its relationship to the conceptual structure thereby providing more organized , as well as new material to strengthen future work. This metaphor serves as a triggering mechanism for visual imagery.

The problem was to combine yarns and fabrics, through various textile processes, (off-loom and on-loom techniques may be incorporated), that involve a personal dimension and an aesthetic value. The specific questions to be examined were the following: 1. How are successful textural surfaces achieved? 2. What kinds of interdependence among color, surface texture, and imagery exist? 3. How foes scale affect the works? 4. In what ways are autobiographical images compatible with the processes?

In the visual arts, I was interested in creating patterns with clay, glass, and metal, utilizing the visual elements (line, color, shape and texture). I arranged, rearranged, and distorted the elements until I obtained a fragmented, yet, unified pattern. My visual ideas were rhythmical (gestural) in nature with or without the direct stimulus of music. Concepts originated in my mind with symbols and sounds simultaneously.

Descriptions of obesity, cerebral palsy, and scoliosis were rank-ordered (from one to twenty) and rated on a five-point scale by 75 college students. The descriptions were of two types: with the appearance of an individual on five levels of severity of a disorder and with the appearance and level of functioning of an individual on five levels of severity of a disorder. The ranking data indicated males rank-ordered descriptions of obese individuals different from cerebral palsy (p < 0.01) and scoliosis (p < 0.05) . The ratings of the descriptions were analyzed in two studies with 2 x 2 x 2 x 5 ANOVA's. Three-way interactions of the level of severity, complexity of description, and type of disorder rated were discussed in terms of likeability of handicapped individuals .

Poems contains fifty-two poems and an afterword that explains some of the ideas that prompted the poems as well as some information about the poetic techniques and allusions. Their primary purpose is to communicate the experiences of a woman living in a patriarchal society, which contemporary American society certainly is. The poems expose how a young woman fits into such a society as a human being and an artist . They stress the need for women writers to play ever-increasing roles in society.

LA31-NRK and B77-NRK are established cell lines that were normal rat kidney cells transformed with temperature-sensitive mutant (LA31) and wild-type Bratislava 77 (B77) of Rous sarcoma virus. It is recognized that many transformation-induced changes differentiate between normal and transformed cells. Morphology and four parameters of transformed cells such as saturation density, anchorage independence, plasminogen activator, and colony stimulating factor were used as indicators to observe the effect of human alpha interferon on the growth of NRK, LA31-NRK and B77-NRK. The results show that interferon could neither reverse the transformed cells to normal fashion nor change their behaviors or cause release of protease.

This study examines the organization, function, and role of public relations in Neiman-Marcus Fortnights. Fortnight is an annual October extravaganza combining cultural and community education with merchandising. Information was gathered by interviews with three people associated with Fortnight public relations. The public relations department follows general goals in planning Fortnight public relations activities. Audiences are not restricted. Public relations responsibilities are publicity, press relations, guest relations, community relations, and special events. Evaluations are made with respect to public relations activities of the previous Fortnight. Though public relations is of secondary importance to merchandising, the effectiveness of Fortnight activities would be improved with established objectives, specific audiences, and a formal means of evaluation.

This study investigated the emotionally disruptive effects of double binding communication, as compared with overtly punitive, and warm, accepting interactions. Forty-two college undergraduates scoring above the mean on the Neuroticism Subscale of Eysenck's Personality Questionaire were each directed to play the part of a small child in a spontaneous role-played family interaction. A pre-post mood test (Multiple Adjective Affect Check List), sensitive to changes in depression, hostility, and anxiety was administered. It was found that subjects in the double-bind and punitive conditions evidenced significant mood disturbance while subjects in the control group did not (all ps < .05). Implications for Double Bind Theory were discussed.

The Raman linewidths of the carbon-halogen stretching mode was measured as a function of temperature in ethyl bromide, isopropyl chloride, isopropyl bromide, t-butyl chloride, t-butyl bromide, chlorobenzene, bromobenzene, iodobenzene and o-dichlorobenzene. The vibrational relaxation times showed a very clear trend. Together with earlier work on methyl iodide, these results provide evidence that the vibrational dephasing efficiencies (T^-1_iso) of the carbon-halogen mode vary in the order of Cl > Br > I. Vibrational dephasing times were calculated from the Fischer-Laubereau Isolated Binary Collision Mode. If further work shows this transferability to extend to other types of skeletal modes in molecular systems, this would have significant ramifications on future vibrational lineshape studies.

Histamine is present in the central nervous system and is believed to be derived from neurons (50 percent) and mast cells (50 percent). This experiment was designed to analyze histologically the numbers and distribution of brain-associated mast cells in normal (+/+), mast cell deficient (W/W^v) and heterozygote (W/+, W^v/+) mice of the WBB6F_1 /J strain. Significant variations in the number and distribution of mast cells between the various genotypes were found. Based on the results, a hypothesis is proposed to account for the observed genotypical differences in mast cell numbers and distribution. Based on the total number of mast cells and the content of histamine in a typical mast cell, it is apparent that the mast cell is not a major source of brain histamine, suggesting that another non-neuronal pool of histamine must be present in the brain.

This paper will show that, despite the need for extension of foreign direct investment in the form of multinational corporations to capital-scarce, less developed countries, political risk creates a gap between the demand and supply of foreign investments. In Chapter II, the patterns of foreign direct investment are analyzed. Chapter III reviews the various sources of political risk and concludes that the existence of political risk is an obstacle to the formation of optimum level investment. Chapter IV discusses the relative positions of the less developed countries and the multinational corporations. Chapter V shows the problems caused by the absence of a universal, regulatory institution. Chapter VI presents case studies of corporations based in Chile, Peru, and Angola. Chapter VII suggests ways that political risk can be minimized.

Literature in semiotics lacks consideration of the elements in symbols that communicate specific concepts. Prohibition was the concept chosen for study. Potential prohibitors were represented by line configurations superimposed on background symbols. Seven prohibitors coupled with symbol backgrounds to form 49 experimental symbols were studied through a symbol inventory. Prohibitors constituted the independent variable, while dependent variables were verbal responses by 105 college students to the experimental symbols. Two hypotheses were tested: a) Prohibitors differ in effectiveness in communicating prohibition and b) Prohibitors differ in frequency of distortion of symbol meaning. Chi square analyses and comparisons of proportions showed diagonal lines most frequently elicited prohibition responses. A chi square analysis displayed no significant relationship between prohibitors in distortion of symbol meaning.

The objectives of these investigations were (1) the purification of MG reductase from sheep liver and (2) studies of some of its characteristics. MG reductase was purified 40 fold and showed a single band on SDS-PAGE. Molecular weight estimations with SDS-PAGE showed a molecular weight of 44,000; although gel filtration with Sephadex G-150 gave a molecular weight of 87,000 indicating that the enzyme might be a dimer. The Km for MG is 1.42 mM and for NADH it is 0.04 mM. The pH optimum for the purified enzyme is pH 7.0. Isoelectric focusing experiments showed a pI of 9.3. In vivo experiments involving rats treated with 3,3',5-triiodothyronine (T_3) and 6-n-propyl-2-thiouracil (PTU) indicated that MG reductase was depressed by T_3 and elevated by PTU.

Each design attempted to fulfill three requirements. The design should be effective as displayed in an exhibition; it should retain its sculptural effect when worn; and it should convey a feeling of envelopment for the wearer. In addition to these requirements, the seven pieces were designed and constructed with four problems in mind. First, how did changes in media or technique effect each garment in terms of surface embellishment, drapability, et cetera? Second, how did the scale of a garment alter the medium or technique used and the pattern shape used? Third, what were the design limitations of both the folded rectangle construction and the wing-sleeve design with triangular pattern shapes? Fourth, were some designs more successful than others in creating an envelopment for the body?

The purpose of this study was to bring a new conceptual quantitative balance to the existing elements in my work thereby establishing a new clarity. It was felt that the above accomplishment would bring about new worth; so that when my work was perceived it would have a greater impact upon the viewer. An expectant visual richness in the imagery would prove that it had been strengthened through simplification of the relationship of form to content. This new visual richness would bring about a new conceptual level to the work, because it had been synthesized into a meaningful statement.

The primary objective of this creative project was to create an environmental performance through the use of light as the principal medium. Most of the photographic imagery had been completed. The remaining task involved creating an effective and workable system to integrate the projected imagery with the neon light placements. Each system, illustrated in the figures, attempted to create a different approach in using the light mediums.

This project was designed to afford me the opportunity to work with the possibility of combining painting and music through the creation of narrative art. I endeavored to produce a body of work in which the individual paintings and songs would also stand on their own as autonomous works, and still function as components of a work that was larger in scope. The challenge was to develop the visual and verbal elements into a unified whole.
