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

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

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 …

Authors, Protagonists, and Moral Decision Making in Contemporary Young Adult Realistic Fiction: a Content Analysis (open access)

Authors, Protagonists, and Moral Decision Making in Contemporary Young Adult Realistic Fiction: a Content Analysis

The purpose of this study was to investigate if there is a difference in the way male and female authors of contemporary realistic fiction for young adults portray decision making by their male or female protagonists. Questions asked in the study were: (1) Do female writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for male protagonists involved in moral decision making? (2) Do female writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for female protagonists involved in moral decision making? (3) Do male writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for male protagonists involved in moral decision making? and (4) Do male writers of contemporary young adult realistic fiction employ an ethic of justice or an ethic of care for female protagonists involved in moral decision making? Content analysis was used as the method of collecting data. The sample consisted of 194 novels written from 1989 to 1998, 53 of which contained a moral dilemma. A discussion of the novels included examples of moral dilemmas, alternative solutions, dilemma resolutions, and resolutions based …

The Blurred Boundaries between Film and Fiction in Salman Rushdie's Midnight's Children, The Satanic Verses, and Other Selected Works (open access)

The Blurred Boundaries between Film and Fiction in Salman Rushdie's Midnight's Children, The Satanic Verses, and Other Selected Works

This dissertation explores the porous boundaries between Salman Rushdie's fiction and the various manifestations of the filmic vision, especially in Midnight's Children, The Satanic Verses, and other selected Rushdie texts. My focus includes a chapter on Midnight's Children, in which I analyze the cinematic qualities of the novel's form, content, and structure. In this chapter I formulate a theory of the post-colonial novel which notes the hybridization of Rushdie's fiction, which process reflects a fragmentation and hybridization in Indian culture. I show how Rushdie's book is unique in its use of the novelization of film. I also argue that Rushdie is a narrative trickster. In my second chapter I analyze the controversial The Satanic Verses. My focus is the vast web of allusions to the film and television industries in the novel. I examine the way Rushdie tropes the "spiritual vision" in cinematic terms, thus shedding new light on the controversy involving the religious aspects of the novel which placed Rushdie on the most renowned hit-list of modern times. I also explore the phenomenon of the dream as a kind of interior cinematic experience. My last chapter explores several other instances in Rushdie's works that are influenced by a filmic …

Breast Cancer Screening Behaviors of Women of Mexican Descent: A Grounded Theory Approach (open access)

Breast Cancer Screening Behaviors of Women of Mexican Descent: A Grounded Theory Approach

A culturally-based theoretical model about how cultural beliefs about cancer and breast cancer screening techniques influence the screening behaviors of women of Mexican descent was developed using grounded theory. Across levels of acculturation and socioeconomic status, 34 women (49 to 81 years old) were interviewed through focus groups. Women who hold more traditional health beliefs about causes, nature, and responsibility with regard to breast cancer are more likely to "feel healthy" and not engage in breast cancer screening. Women who hold more traditional beliefs about propriety of female and health care provider behavior are more likely to "feel indecent" and also not engage in screening. The cultural health belief model is integrated within a sociocultural and a socioeconomic context.

Brief Symptom Inventory: Music and Non-Music Students (open access)

Brief Symptom Inventory: Music and Non-Music Students

The present study is a comparison of music and non-music students with respect to their response patterns on the Brief Symptom Inventory as well as several demographic questions. The sample consisted of 148 non-music students and 141 music students at three levels: (1) freshmen/sophomore; (2) juniors/seniors; and (3) graduate students. Music students consisted of volunteers from several different music classes and non-music students were volunteers from non-music classes. There were no significant differences found among or between groups for the BSI subscales. However, music students were significantly less likely to have gone to counseling in the past and to seek professional counseling for future problems. Recommendations for psycho-educational interventions with musicians are discussed as well as suggestions for future research.

Characteristics of Children With Behavior Disorders Who Drop Out of Therapy (open access)

Characteristics of Children With Behavior Disorders Who Drop Out of Therapy

The purpose of this study was to examine the characteristics that distinguish children with behavior disorders who drop out of psychotherapy treatment from those who remain in treatment. The sample included 379 children (268 male and 111 female) who were diagnosed with a behavior disorder at Dallas County Mental Health/Mental Retardation (MH/MR), a community mental health clinic in Dallas, Texas. The results indicated that certain characteristics increased the likelihood that a child would drop out of therapy, including reliance on aid, the presence of maternal psychopathology, and more severe externalizing and internalizing behaviors. This study also found that younger children with behavior disorders had a greater probability of dropping out of treatment. Minority status, gender, parent marital status, and referral source were not found to be associated with dropping out of treatment. Future studies should focus on specific interventions that clinicians could employ to deter premature termination from treatment.

Characterization of Low Barrier Hydrogen Bonds in Enzyme Catalysis: an Ab Initio and DFT Investigation (open access)

Characterization of Low Barrier Hydrogen Bonds in Enzyme Catalysis: an Ab Initio and DFT Investigation

Hartree-Fock, Moller-Plesset, and density functional theory calculations have been carried out using 6-31+G(d), 6-31+G(d,p) and 6-31++G(d,p) basis sets to study the properties of low-barrier or short-strong hydrogen bonds (SSHB) and their potential role in enzyme-catalyzed reactions that involve proton abstraction from a weak carbon-acid by a weak base. Formic acid/formate anion, enol/enolate and other complexes have been chosen to simulate a SSHB system. These complexes have been calculated to form very short, very short hydrogen bonds with a very low barrier for proton transfer from the donor to the acceptor. Two important environmental factors including small amount of solvent molecules that could possibly exist at the active site of an enzyme and the polarity around the active site were simulated to study their energetic and geometrical influences to a SSHB. It was found that microsolvation that improves the matching of pK as of the hydrogen bond donor and acceptor involved in the SSHB will always increase the interaction of the hydrogen bond; microsolvation that disrupts the matching of pKas, on the other hand, will lead to a weaker SSHB. Polarity surrounding the SSHB, simulated by SCRF-SCIPCM model, can significantly reduce the strength and stability of a SSHB. The residual strength …

Charge conjugation invariance of the spectator equations (open access)

Charge conjugation invariance of the spectator equations

In response to recent criticism, the authors show how to define the spectator equations for negative energies so that charge conjugation invariance is preserved. The result, which emerges naturally from the application of spectator principles to systems of particles with negative energies, is to replace all factors of the external energies W {sub iota} by {radical} W{sup 2} {sub iota}, insuring that the amplitudes are independent of the sign of the energies W {sub iota}.
