An Assessment of the Use of Seeding, Mowing, and Burning in the Restoration of an Oldfield to Tallgrass Prairie in Lewisville, Texas

An Assessment of the Use of Seeding, Mowing, and Burning in the Restoration of an Oldfield to Tallgrass Prairie in Lewisville, Texas

Date: August 1999
Creator: Windhager, Steven
Description: An examination of the effectiveness of seeding, burning, and mowing in the reestablishment of tallgrass prairie species on overgrazed and abandoned pastureland. The study site is a 20 acre tract on U.S. Corps of Engineers land below Lake Lewisville in Denton County, Texas. The site was partitioned into thirty-nine 40 by 40 meter plots with seeding (carried out in 1996) and management treatment (burning, mowing, and no maintenance carried out in 1998) randomly applied following a two level design. For each plot, nine stratified-random 0.1 m2 subplots were examined and shoot counts for each species recorded. The effects of the treatments on individual species and species richness were analyzed with a two-way ANOVA followed by a SNK multiple range test, both on ranked data. Community level analysis was conducted with both a MANOVA on ranked data and a Canonical Correspondence Analysis on raw data. Results indicate that seeding positively affected species richness, particularly when combined with either burning or mowing in the early spring. Mowing also significantly increased species richness in areas that were not seeded, while burning negatively affected species richness on unseeded plots. Treatments significantly affected community composition with treatments having the most clear effect on spring and ...

Girl Power: Feminism, Girlculture and the Popular Media

Girl Power: Feminism, Girlculture and the Popular Media

Date: August 1999
Creator: Smith, Ashley Lorrain
Description: This project is an interrogation of three examples from recent popular culture of girlculture, specifically texts that target young female consumers: the Spice Girls, Scream and Buffy the Vampire Slayer. These examples are fundamentally different than texts from earlier female targeted generic models because they not only reflect the influence of the feminist movement, they work on feminism's behalf. The project's methodology grows out of feminist film theories and cultural studies theories. One chapter is dedicated to each text, and each reading works to reappropriate girlculture texts for a counter-hegemonic agenda by highlighting the moments when each text manages to subvert its mass mediated conservative biases.

The Effects of Shaping and Instruction-based Procedures on Behavioral Variability during Acquisition and Extinction

The Effects of Shaping and Instruction-based Procedures on Behavioral Variability during Acquisition and Extinction

Date: December 1999
Creator: McCary, Donald
Description: This study examined effects of two response acquisition procedures on topography of responding using the revealed operant technique and compared results to previous experiments on this topic. Subjects emitted 100 repetitions each of 4 response patterns on a continuous schedule of reinforcement. A 30-min extinction condition followed acquisition. One group of subjects learned the first response through a series of shaping steps designed to reduce acquisition variability. Another group of subjects was instructed in the correct response topography and was told there was no penalty for attempting other sequences. The first group of subjects produced high variability during extinction despite reduced variability in acquisition. The second group of subjects responded with moderate to high variability during extinction and little variability during acquisition. Most extinction responses for the first group were variations of the last pattern reinforced. Most extinction responses for the second group were repetitions of the last pattern reinforced.
