In this study organisms that can be subcultured from lake water, using a prescribed procedure, limit, to an extent, the population, or portions of the population, that can be monitored. In essence, what is taking place is that a set of conditions is set forth and a study is made of the bacteria that will grow under these prescribed conditions.

The purpose of this thesis is to provide a descriptive study of psychiatric and social variables related to aged first admissions to a private psychiatric hospital in the calendar years 1959 through 1963. The study also seeks to determine what, if any, relationship exists between background characteristics of the patients and their diagnoses. Finally, the diagnosis of the patient is compared with a series of patient outcome variables to determine the relationship, if any, between diagnosis and selected recovery variables. Due to the nature of the data used, the emphasis of the thesis is upon describing relationships rather than testing hypotheses.

This study was conducted to determine if high-creative college students differ from low-creative college students on an objective measure of personality. An additional purpose was to determine if university drama majors are more creative than non-drama majors.

It was the purpose of this study to attempt to discover if the educational background and judgment ability of juvenile delinquents are markedly impaired, as indicated by the Information and Comprehension subtest scores of the Wechsler Intelligence Scale for Children.

It is the aim of this investigation to compare the use of normally recommended toys, ordinarily used in the play-therapy setting, with more sophisticated, "grown-up" toys, when working with twelve-year-old children.

The present study is an attempt to determine which of several different types of reinforcers is most effective in discrimination learning using institutionalized mentally retarded boys of different intellectual levels as subjects. If one type of reinforcement works more effectively in conditioning one level of institutionalized mentally retarded subject, then that type of reinforcement could be used to greater advantage in controlling behavior than some other, less effective kind of reinforcer.

The major problem investigated was to ascertain the extent to which a training program designed specifically to increase frustration tolerance would reduce selected behavioral problems in institutionalized mentally retarded children. Of lesser importance was the problem of examining the extent to which the prescribed training program had differential effects on brain-injured and non-brain-injured retarded children.

It has not yet been demonstrated that music can be used therapeutically with profoundly retarded children. One way these children might be helped to respond to music, and therapeutically benefit from it, would be to use operant conditioning in an effort to enhance gross motor activity and then progressively shape responses until more complex behavior patterns are formed. Once these children can respond motorically in the presence of musical stimuli, continuation of responding may be possible by pairing motor activity with musical stimuli. This experiment investigated the effects of operant conditioning and music on the motor activity of profoundly retarded children in an effort to determine the therapeutic usefulness of music with such children.

This study is concerned with the political impact of the Supreme Court's decisions concerning state legislative apportionment. First, an attempt is made to describe the political environment in which they were made, with special reference to the existing bases of representation in the states and the political reaction to the decisions. Secondly, the study traces the major issues relating to judicial enforcement of the apportionment standards enunciated by the Supreme Court and the modification and development of those standards that followed the initial decisions. Finally, the extent to which reapportionment has been successfully enforced by the courts may suggest some tentative conclusions about the viability and utility of the equal population doctrine as a constitutional standard, as well as some of the possible political consequences of enforcement of that standard.

This thesis relates the expeditions of General Narcio Lopez in 1850-1851, and the influence he had in the southern United States.

The question of maladjustment of individuals with speech defects and its subsequent manifestation is the basic issue of this thesis. The study was conducted to answer the question: "What is the incidence of speech defects among juveniles exhibiting antisocial aggressive behavior?"

The purpose of this research is to determine whether or not meaningful differences exist along these dimensions in the manner in which social workers view their work role, and whether or not any such differences are related to the bureaucratic and professional nature of the agencies and their employees. The analysis will attempt to define the points at which the bureaucratic organization conflicts with professional patterns of organization and attempt to discover the mode of accommodation which results from these conflicts.

The purpose of this study was to investigate the various aspects of low-power frequency modulation educational broadcasting and to formulate from the findings a guide for the establishment of stations on campuses as exemplified at Oklahoma Baptist University. It is hoped that this report will provide detailed information of interest and value to that university, its staff, its present and future scholars, and to other school and individuals interested in building an educational broadcast facility.

The purpose of this study was to determine the relationship between articulation ability and reading ability, between articulation ability and language development, and between language development and reading ability. This study examined children with minor difficulties and children with a history of more severe articulation problems separately in order to determine whether severity of articulation disability is related to reading ability.

This thesis describes the history surrounding Silas Wright and the anti-rent agitation in New York during the 1840's.

The problem of this study was the relationship between practices reported by American history teachers in selected Texas secondary schools and practices recommended by three groups of social studies authorities.

The major purposes of this study were (1) to obtain information relating to the number and types of areas of work included in the routine duties performed by the maintenance employees employed in a selected group of Acme Brick Company production plants, (2) to determine the nature of any training that may have assisted in the development of their ability to perform the skills normally involved in each area of work, and (3) to recommend to Acme Brick Company areas of instruction to be included in a training program for its employees.

The major purposes of this study were to gather information on the employment status and location of students who completed four or more courses in the technical-industrial program at Tyler Junior College, Tyler, Texas; to identify factors that influenced them in selecting Tyler Junior College and taking courses in the technical-industrial program; to ascertain in some measure the effectiveness of the training these students received in preparing them for the positions they have held and now hold; and to secure data and information which the faculty and administration at Tyler Junior College may use in evaluating the present program with respect to future changes and improvements.

The purpose of this study was to indicate if there exists a need for additional learning experiences in the area of vocational and industrial arts education at Lawrence D. Bell High School. The information acquired from the check list, combined with other related studies, should help establish valid guide lines for curriculum development in this area. This study should provide information as to whether or not the needs of the terminal student and the college preparatory student are dissimilar.

This is a study to develop standards to be use by industrial arts teachers, school administrators, and architects when planning new industrial arts laboratories or renovating existing industrial arts laboratories for grades seven through twelve in the State of Texas.

The design of this experiment was developed to investigate the presence of success-striving and failure-avoidant motivational patterns in the level of aspiration behavior of retarded subjects. The primary objective of this study is to show that success-strivers are present in mentally retarded groups, even if in the minority.

This thesis describes experimental work done in art education with a small group of children that met each Saturday at Dallas Services for the Blind over a two year period. The research used textured collage art projects as the medium of artistic expression for the children.
