A comparative study of the use of the Abrams High School library in Bessemer, Alabama by two track program students, 1963
Get PDFThe differences between the leadership styles of male and female public school principals and the relationship to teachers' perceptions of effectiveness, 1997
Get PDFThis study investigated the leadership styles of male and female principals and the relationship to the teachers' perceptions of effectiveness. The study also investigated four categories of leadership style: Laissez Faire, Democratic-Cooperative, Autocratic-Submissive, and Autocratic-Aggressive, and how these styles impact the teachers' perceptions of the principals' effectiveness. Two questionnaires were administered to gather data from teachers and principals in the Fulton County School System, a large urban system in metropolitan Atlanta, Georgia. The Leadership Ability Evaluation (LAE) was completed by principals to determine their leadership style, and the Instructional Leadership Evaluation and Development Program (ILEAD) was completed by the teachers to determine their perceptions of the principals' effectiveness. The findings of this study determined that there is no significant difference between the leadership styles of male and female principals. The findings also suggests that there is a relationship between the principals' leadership style and the teachers' perceptions of effectiveness, however the relationship is not significant. Finally, the findings indicated that when gender is compared to leadership style and teachers' perceptions of effectiveness there was no significant relationship. The study is significant because not only does it add to the body of literature, but it also shows that leadership style is a greater determinant of teachers' perceptions effectiveness than gender. The findings of this study may also be used as a catalyst to encourage the placement of more females in leadership positions in order to make the percentage of female principals more consistent with the percentage of female teachers
An examination of the citizens' participation in development management in the region of Segou (Republic of Mali), 1989
Get PDFFrom mid 1970s, the Republic of Mali embarked on an administrative reform program aimed at encouraging citizens' participation in development. The purpose of this degree paper was to examine some of the problems associated with participatory development in Mali using the Region of Segou as a case study a decade after the formal declaration of the national policy. This study is significant because traditionally citizens were not allowed to participate whatsoever in the decision-making process. Even with the advent of independence, it was only the elites within the society who participated. Thus, this new approach at democratization of the decision-making process is both exciting and full of challenges. The major findings of the study are that in spite of the perception of the citizens that some improvements have taken place since the reforms of the 1970s, citizen participation has been plagued by four barriers, namely (a) socio-religious, (b) organizational, (c) legal and (d) economic. The primary source of information was the administration of a survey instrument to citizens. Secondary data were obtained from a variety of sources including government publications, books, and journals
A comparative study of microsclerotial development in wild type and microsclerotial mutants of verticillium dahi.iae, 1979
Get PDFThe purpose of this study was to compare a wild type strain of Verticillium dahliae (t9) with two of its mutants, albino 4 (aim 4) and brown 1 (brm 1). Techniques of phase contrast microscopy and electron microscopy were used. The strains were grown in a medium which allowed synchronous development of microsclerotia and were harvested at 3 days. Microsclerotia resulted from conidia that had enlarged followed by germination. An analysis of conidia production suggested that their modes of microsclerotia production were basically the same. The most noticeable differences at the electron microscopic level were differences in nuclear structure and occurrence of single and double membrane bound structures among the three strains. For example, aim 4 exhibited intensely stained chromatin material along with the appearance of virus like particles. The single membrane bound structures were found only in aim 4 and melanin producing (t9) strains, while the double membrane bound structures were found in all three strains

The relationship between temperature and the contraction and expansion of melanophores from tadpoles of rana pipiens grown in vitro, 1962
Get PDFDoes Frasier's black bourgeoisie describe Atlanta's blacks?, 1984
Get PDFThe purpose of this dissertation is to determine whether E. Franklin Frazier1s theses about the Black middle class are true of Atlantans. The most authoritative and comprehensive theory on the Black middle class remains his Black Bourgeoisie. Yet, Frazier's assertions ignited firestorms of controversy which rage to the present day. None of his major claims found universal acceptance. An examination of Frazier's purpose as well as his philosophical, theoretical, academic, and social background places Frazier's definitions and theses in the context of contemporary social scientists and reveals some of the confusions in Frazier's own writing and in that of his critics. The literature on Frazier and on the key assertions about the Black middle class were reviewed in order to determine both what is claimed about this phenomenon as well as what weaknesses in its investigation must be avoided if this controvery is to be resolved. These critiques are taken into account by an empirical investigation designed to either refute Frazier's claims or to remove those clouds. Three major types of original research are presented: content analyses of newspapers, analyses of election statistics, and 293 interviews with six groupings of Black bourgeoisie: business people, clergy, faculty, lawyers, doctors, and residents of middle class neighborhoods. The interviews focus on four key Frazier theses: social responsibility, accommodationism/conservatism, rejection as peers by whites, and negative self-assessment. Overall, Frazier's theses were confirmed for Atlantans. However, negative self-assessment is less today. Further, the Black bourgeoisie does not appear to have the degree of hostility toward the poor that Frazier claimed. The Atlanta's Black bourgeoisie continues to oppose invidious racial discrimination, but doubts were cast upon their vision, social responsibility, will, and power as leaders of the Black community in areas outside what Frazier defined as 'racial radicalism.' A philosophy, and a theory of race relations severely limits its ability to consider and implement the full range of available values, goals, and strategies. Since the works on the Black middle class can be characterized as footnotes to Frazier's classic, some of them should be reassessed. This includes at least parts of the work of Ronald Semone, Sidney Kronus, and Will Tate. This study confirmed the relevant parts of the work of Spencer Condie and James Christiansen, W. E. B. Du Bois, Gundar Myrdal, St. Clair Drake and Horace Cayton, Jack Walker, Nathan Hare, Floyd Hunter, Harry Holloway, and William Muraskin
A study of a nonseptate mutant of schizophyllum commune at the cellular level, 1984
Get PDFIn the tetrapolar bas i di omycete Schizophyl 1 uni commune a mutation in strain 9004 (chocolate) impairs hyphal growth as well as brings about an accumulation of extracellular granules and nonseptate condition. A higher amount of resi�dual glucose was observed in the growth medium of the choco�late mutant. Estimation of crude protein showed that the mutant contained more crude protein in its growth medium as compared to that of the wild-type. Partial and complete hydrolysis of the mutant cell wall demonstrated that it is mainly composed of small amounts of chit in and two glucans called S and R-glucan, and that its S/R ratio is low. The incorporation of labeled uridine diphosphate-N-acetyl-D-glucosamine in cell-free extracts of the chocolate mutant of Schizophyl1 urn commune showed very low incorporation into insoluble chitin of the mutant. All of the above evidence suggest that there is lesion or weak�ness in the chocolate cell wall and this may be affecting the general physiology of the mutant.An ultrastructural observation of the hyphae revealed a wider cell wall in the mutant as compared to that of the wild-type. Besides, the study showed that there is an increased number of vacuoles and intrusion in the subapical region. SEM and TEM exhibited cytoplasmic materials and exudate, respectively, which were secreted by the chocolate mutant
