Phagocytosis by Earthworm Coelomocytes : A Biomarker for Immunotoxicity of Hazardous Waste Site Soils

Phagocytosis by Earthworm Coelomocytes : A Biomarker for Immunotoxicity of Hazardous Waste Site Soils

Date: December 1997
Creator: Giggleman, Marina A.
Description: Several biomarkers (cell viability and phagocytosis) based on earthworm (Lumbricus terrestris) immune cells (coelomocytes), together with whole-worm mortality (LC/LD50's), were used to assess a bioremediation attempt to reduce pentachlorophenol (PCP) toxicity in a former wood processing hazardous waste site (HWS).

Pieter Bruegel the Elder's Apocalyptic Fortitude

Pieter Bruegel the Elder's Apocalyptic Fortitude

Date: December 1997
Creator: Burris, Suzanne Lynn
Description: This thesis examines Pieter Bruegel the Elder's Fortitude, 1560, a print from the Seven Virtues series. Fortitude stands out as an anomaly within the cycle because it contains several allusions to the Book of Revelation. The linkage of Fortitude to the writings of St. John is important because it challenges previous iconographic and iconological analyses of the composition. Analysis of Fortitude's compositional elements is provided, along with an examination of the virtue tradition. Additionally, an exploration of sixteenth-century apocalypticism is included, as well as an examination of the artistic influences that may have inspired Bruegel. This thesis concludes that Fortitude's apocalyptic allusions do not seem unusual for an artist familiar with St. John's prophecies, influenced by Hieronymus Bosch, and living in an age of apocalypticism.

Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904

Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904

Date: December 1997
Creator: Carawan, James T. (James Terry)
Description: This thesis challenges the traditional interpretation of the history of Populism in America through the use of an intensive regional study. Using precinct-level returns, this thesis proves that, contrary to the conclusions of more general studies, voters from predominately Populist areas in North Texas did not support the poll tax amendment that passed in November 1902. The Populists within this region demonstrated their frustration and distrust of the political process by leaving the polls in higher percentages than other voters between 1896 and 1902. The Populists that did participate in 1902 reentered the Democratic Party but did not support the poll tax, which was a major plank within the Democratic platform. This thesis also proves that the poll tax had a significant effect in reducing the electorate in North Texas.

The Process of Sharing Team Leadership : A Study of Key Leadership Behaviors and Who Exhibits Them

The Process of Sharing Team Leadership : A Study of Key Leadership Behaviors and Who Exhibits Them

Date: December 1997
Creator: Horner, Melissa A. (Melissa Amy)
Description: Using a manufacturing setting that is organized into self-managed teams, the current study identified and measured key leadership behaviors within the teams. Questions that were asked include: are some team leadership behaviors more critical to a team's level of functioning than other behaviors? and do successful self-managed teams rely on formal leadership to a lesser extent than members of less successful teams? These questions were asked in the context of leadership as a process, not an individual.

The Relationship between Hardiness and Responses to Life Events in Adulthood

The Relationship between Hardiness and Responses to Life Events in Adulthood

Date: December 1997
Creator: Crowley, Barbara Jo
Description: The relationship between psychological hardiness and individuals' coping with two life events, involuntary job loss and post-parental launching of adolescent children, was investigated in a sample of 146 adults, 83 of which had experienced job loss and 61 of which had experienced the empty nest. Volunteers completed questionnaires which measured hardiness, distress, coping strategies, neuroticism, and extraversion. Multivariate analyses were performed, both with and without covariates, for overall hardiness as well as the hardiness subscales of control, commitment, and challenge. Significant hardiness by life event interactions on escape-avoidance coping were found in both sets of analyses. Main effects for hardiness, however, disappeared when controls for neuroticism and extraversion were utilized. Findings underscore the necessity of employing neuroticism controls in future hardiness research.

The Relationship of Developmentally Appropriate Beliefs and Practices of Greek Kindergarten Teachers

The Relationship of Developmentally Appropriate Beliefs and Practices of Greek Kindergarten Teachers

Date: December 1997
Creator: Syrrakou, Ioanna
Description: Sixty Greek kindergarten teachers were surveyed regarding their teaching beliefs and practices using the Teachers Questionnaire based on guidelines recommended by the National Association for the Education of Young Children. A Varimax factor analysis produced four factors for the Teacher Belief Scale and five factors for the Instructional Activities Scale. Scores on developmentally appropriate factors were consistently higher than factors classified developmentally inappropriate. Correlation between appropriate beliefs and activities was significant (r = .470); correlation between inappropriate beliefs and practices was significant (r = .475). However, developmentally inappropriate beliefs were also positively correlated with developmentally appropriate practices (r = .537). Developmentally appropriate beliefs were not correlated with inappropriate practices. Results were discussed with possible theoretical and practical implications for future research and teacher development.

The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations

The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations

Date: December 1997
Creator: Michniewicz, Leslie (Leslie A.)
Description: The role of point loss for symmetrical relations introduced simultaneously with probe trials in the absence of original relations on all probe trial performances was evaluated. Training was completed after six conditional discriminations were established in two contexts. Point loss was introduced simultaneously with probe trials in the absence of original relations in the first context. Probe trials with no point loss in the absence of original relations were introduced in the second context. The simultaneous introduction of probe trials and the point loss contingency may in some cases prevent the emergence of an equivalence class in the context that contained the point loss as well as in the context where no point loss occurred.

Saving Society Through Politics: the Ku Klux Klan in Dallas, Texas in the 1920s

Saving Society Through Politics: the Ku Klux Klan in Dallas, Texas in the 1920s

Date: December 1997
Creator: Morris, Mark N. (Mark Noland)
Description: This study analyzes the rise of the 1920s Ku Klux Klan in Dallas, Texas, in the context of the national Klan. It looks at the circumstances and people behind the revival of the Klan in 1915. It chronicles the aggressive marketing program that brought the Klan to Dallas and shows how the Dallas Klavern then changed the course of the national Klan with its emphasis on politics. Specifically, this was done through the person of Hiram Wesley Evans, Dallas dentist and aspiring intellectual, who engineered a coup and took over the national Klan operations in 1922. Evans, as did Dallas's local Klavern number 66, emphasized a strong anti-immigrant, anti-Catholic ideology to recruit, motivate, and justify the existence of the Ku Klux Klan. The study finds that, on the local scene, the Dallas Klavern's leadership was composed of middle and upper-middle class businessmen. Under their leadership, the Klan engaged in a variety of fraternal and vigilante activities. Most remarkable, however, were its successful political efforts. Between 1922 and 1924, the Klan overthrew the old political hierarchy and controlled city and county politics to such a degree that only the Dallas school board escaped the Invisible Empire's domination. Klavern 66 also wielded ...
