Aspects of the Thermal Ecology of Largemouth Bass (Micropterus salmoides) in North Central Texas (open access)

Aspects of the Thermal Ecology of Largemouth Bass (Micropterus salmoides) in North Central Texas

The coefficient of body temperature change (K) ranged from -0.53 to -0.072 for bass weighing 73-1440 g. The double log regression of K on weight was similar to that reported for other poikilotherms (slope = -0.57; R = 0.93). Fingerling bass were eurythermal, being capable of surviving instantaneous temperature changes over a 20 C range at acclimation temperatures of 15, 25 and 30 C and over a 15 C range at acclimation temperatures of 20 and 35 C. Preferred temperatures for adult bass measured in the laboratory ranged from 27-32 C with no relationship to day or night. The overall mean preferred temperature was 29 C. The laboratory determined preferred temperatures were supported by limited field determined body temperatures taken in a vertical temperature gradient near the discharge of a power plant effluent. Routine metabolic rates of bass from a heated reservoir and a nearby hatchery were similar from 10-30 C in summer and winter. The weight exponent (0.77) and Q^gS (1*6-2.9) were similar to those published for more northern bass populations; however, the Texas bass had lower metabolic rates than those published for the northern populations. Bass exposed to rapid temperature increase (0.2 C/min) from 25-30 C increased their …

Charlotte Perkins Gilman: A Humanist Approach to Feminism (open access)

Charlotte Perkins Gilman: A Humanist Approach to Feminism

Charlotte Perkins Gilman (1860-1935), writer and lecturer, provided philosophical guidance to the feminist movement of the late nineteenth and early twentieth centuries, During a career spanning the years 1890 to 1935 she published eleven books, wrote articles for popular magazines, and lectured throughout the United States and Europe. Between 1909 and 1916 she wrote, edited, and published a monthly magazine entitled The Forerunner. Gilman's efforts dealt primarily with the status of women, but she described herself as a humanist rather than a feminist. She explained that her interest in women arose from a concern that, as one-half of humanity, their restricted role in society retarded human progress. Thus, Gilman's contribution to feminism must be viewed within the context of her humanist philosophy. Gilman's contribution to feminism lies in her diagnosis of woman's predicament as ideological rather than political and, hence, subject to self-resolution. The uniqueness of Gilman's approach is in the autonomous nature of her solution: Woman, through the full use of her human powers, could achieve the equality that decades of political agitation had failed to accomplish. The rationale for this dissertation lies in the premise that Gilman's humanist approach to feminism made a significant contribution in her own …

A Study of Executive Professional Leadership of Principals within the Elementary Schools of Texas (open access)

A Study of Executive Professional Leadership of Principals within the Elementary Schools of Texas

This study investigated the relationship of Executive Professional Leadership of principals in the elementary schools of Texas with specific factors which influence the quality of instruction. The primary purpose was to determine the significance to which the level of Executive Professional Leadership correlates with teacher morale, teacher performance, school organizational climate, and selected personal attributes of the elementary school principal. This study concluded that the elementary school principal who is effective in motivating his staff and improving its standards and performance in teaching (1) creates a social climate conducive to the development of high morale in the teachers, (2) sets the standard of behavior expected of his staff, (3) creates the kind of organizational climate conducive to the development of a quality school program, and (4) has the ability to effectively handle delicate situations such as complaints by parents and problems of discipline. Also, this study concluded that (1) experience in elementary teaching, (2) level of self-assessment as an educational leader, (3) internalization of the professional leadership definition, and (4) importance of routine administrative functions have no bearing on the elementary school principal's effectiveness in motivating his staff and improving its standards and performance in teaching.

The Impact of a Model Cities Program on the Convergence of Crime Rates in a Model City Area and Residual Areas (open access)

The Impact of a Model Cities Program on the Convergence of Crime Rates in a Model City Area and Residual Areas

One purpose of the national Model Cities Program was to reduce the incidence of crime and delinquency in poverty blighted areas to levels prevailing in the remainder of the community. A measurable goal projected by the Austin program was to reduce crime in its Model City Area (in comparison to the rest of the city) by at least 8.73 per cent during the operational years of the program. The central problem of the study was to examine the relationships between official crime rates in the Austin Model City Area in comparison to residual areas of the city. Robbery, burglary, and auto theft rates were singled out for intensive study over the six year operational period of the program to see if they were converging with comparable rates in the rest of the city. Ultimate implication: the Model Cities Program was probably a contributing factor in the reduction of selected crimes in the Model Neighborhood and census tracts containing it.

A Comparison of Job Corps Graduates and Non-Graduates with Respect to Selected Academic and Psychological Variables (open access)

A Comparison of Job Corps Graduates and Non-Graduates with Respect to Selected Academic and Psychological Variables

The problem with which this investigation is concerned is that of determining the academic as well as psychological differences between the McKinney Texas Job Corps graduates and non-graduates. The purpose of the study is to gain knowledge that will be useful in the guidance of Job Corps students. Nine hypotheses were formulated to investigate the relationship between academic achievement and certain selected academic and psychological variables. It was concluded that significant personality differences do exist among the McKinney Job Corps graduates and non-graduates. Chronological age is a significant variable with respect to success at the Job Corps Center. Academic variables are not useful indicators of success at the Job Corps training program.

The Origins and Development of Black Religious Colleges in East Texas (open access)

The Origins and Development of Black Religious Colleges in East Texas

This work is a study of the origins, development, and contributions of the black religious colleges of East Texas. The central purpose of the study is to reexamine the role Wiley, Bishop, Texas, and Jarvis colleges have played in black higher education. Although prior to 1960 most studies of Negro institutions of higher education described such schools as total failures in their effort to uplift American Negroes, since that time many scholars have published works which pointed up the achievements as well as the problems of those colleges. In addition to their efforts to provide the Negro community with capable leaders, the black religious colleges of East Texas also directed public service projects. Especially beneficial, these efforts, which included farm demonstration programs and home demonstration classes, were designed to help black people at whatever level needed. Wiley, Bishop, Texas College, and Jarvis have not been total failures. Although always academically weak, they have served the black community well. However, in spite of the valuable service they have rendered, unless these schools can generate new and larger sources of revenue, they stand little chance of remaining viable institutions. Each of these colleges desperately needs more money. Ironically, it may be that …
