Cloning of Carbonic Anhydrase from Cotton (Gossypium hirsutum L.)

Cloning of Carbonic Anhydrase from Cotton (Gossypium hirsutum L.)

Date: December 1998
Creator: Local, Andrea
Description: Carbonic anhydrase is a ubiquitous zinc-metalloenzyme that catalyzes the interconversion of carbon dioxide and carbonate and has been found to play a wide range of roles in animals, plants and bacteria. Cotton genomic and cDNA libraries were screened for the plastidial isoform of carbonic anhydrase. The nucleotide sequences of two 1.2 Kb partial cDNA clones were determined. These clones exhibit high homology to carbonic anhydrases from other dicot plants and possess all the expected peptide motifs. For example, serine and threonine rich chloroplastic targeting peptide and conserved zinc binding residues are both present. These clones were utilized to isolate two carbonic anhydrase genes that were shown to encode different isoforms by PCR and RFLP analysis.

A Comparative Study of the Impact of the Total Quality Management Program on Exit Level Texas Assessment of Academic Skills Scores

A Comparative Study of the Impact of the Total Quality Management Program on Exit Level Texas Assessment of Academic Skills Scores

Date: December 1998
Creator: Maulding, Wanda Smith
Description: The management style being used by school personnel in Texas and across the nation today is predominately that of a bureaucracy. This model was organized around the industrial revolution that was exercising authority at the turn of the century. Writers and researchers have pointed out that such a model is not capable of providing students the knowledge and skills they will need to enter an increasingly demanding society. One management style relatively new to the educational arena today is that of Total Quality Management. This study reports the results of the impact of the training in those principles by measurement of student test scores.

Corporate Propaganda Analysis: a Case Study of Nike, Inc.

Corporate Propaganda Analysis: a Case Study of Nike, Inc.

Date: December 1998
Creator: Anderson, Christian S. (Christian Spencer)
Description: This study seeks to show how Nike, Inc. has effectively followed a strategy to increase the sale of its products that can be characterized as propaganda. Regarding method, this is a qualitative study which applied the propaganda analysis plan developed by Jowett & O'Donnell (1992) to examine and describe (1) Nike's ideology, (2) corporate structure and culture, (3) purpose, (4) targeted audiences, (5) the dissemination of the propaganda, (6) techniques for increasing its effectiveness, (7) existing counterpropaganda and contradictions, and (8) the effectiveness of the campaign. The study provides evidence that Nike engages in propaganda through an organized, systematic, and deliberate attempt to influence the beliefs, attitudes, perceptions, and actions of specific audiences for the purpose of accomplishing fixed objectives.

Cottonseed Microsomal N-Acylphosphatidylethanolamine Synthase: Identification, Purification and Biochemical Characterization of a Unique Acyltransferase

Cottonseed Microsomal N-Acylphosphatidylethanolamine Synthase: Identification, Purification and Biochemical Characterization of a Unique Acyltransferase

Date: December 1998
Creator: McAndrew, Rosemary S. (Rosemary Smith)
Description: N-Acylphosphatidylethanoiamine (NAPE) is synthesized in the microsomes of cotton seedlings by a mechanism that is possibly unique to plants, the ATP-, Ca2+-, and CoA-independent acylation ofphosphatidylethanolamine (PE) with unesterified free fatty acids (FFAs), catalyzed by NAPE synthase. A photoreactive free fatty acid analogue, 12-[(4- azidosalicyl)amino]dodecanoic acid (ASD), and its 125I-labeled derivative acted as substrates for the NAPE synthase enzyme.

Culture and Anxiety: a Cross-Cultural Study

Culture and Anxiety: a Cross-Cultural Study

Date: December 1998
Creator: Abbassi, Amir
Description: By measuring interactions among and between anxiety and the independent variables of country of origin, gender, level of education, and age, this study attempted to gain insight into how students from different countries experience anxiety on a U.S. college campus. Results of the Multivariate Analysis of Variance (MANOVA) and the univariate test(ANOVA) indicated that the gender and level of education of the subjects made no significant difference. However, when it came to country of origin, there were significant differences between two of the cultural groups and respective anxiety level. Findings also support a positive correlation between age and anxiety levels, with the youngest participants having the lowest anxiety levels.

The Determinants of Federal Spending for the Administration of Justice

The Determinants of Federal Spending for the Administration of Justice

Date: December 1998
Creator: Gabriano, Gina
Description: This study develops and empirically tests a model of the determinants of federal spending for crime-fighting policies. An inter-disciplinary approach to building the model is utilized that merges ideas from budgeting, policy analysis and criminology. Four factors hypothesized to impact federal spending for the administration of justice are operationalized as eight variables and tested using ordinary least squares regression analysis on time series data. The factors hypothesized to impact federal spending in this area are economic constraints imposed on government spending, the ideological makeup of Congress and the president, the actual crime rate, and the public's attitude toward crime. Five of the eight variables demonstrated statistical significance at the.10 level or better.

Do American Adults Know How to Exercise for a Health Benefit?

Do American Adults Know How to Exercise for a Health Benefit?

Date: December 1998
Creator: Krzewinski-Malone, Jeanette A. (Jeanette Aileen)
Description: Approximately 950,000 Americans die annually from cardiovascular disease. Physical activity is a major risk factor for the development of CVD and a risk factor for stroke. The purpose of this research was to determine whether American adults know how to exercise to achieve health benefits and whether this knowledge is a function of demographics. Items included knowledge of exercise guidelines and knowledge of traditional and non-traditional exercise activities. This information was obtained from 22 questions that were a part of a larger national survey of 2,002 American households. Statistical analyses of this sample, indicate American adults have knowledge which varies by demographic groups. Data revealed that overall the 61+, Less than High School, African-American, Hispanic-American, and Male groups have the least amount of knowledge about exercise. These data can provide health educators with important aspects of exercise knowledge for future health promotions/interventions.

Ecological Association Between the Red-Cockaded Woodpecker and Southern Pine Beetle in the Homochitto National Forest: a Geographic Information System Approach

Ecological Association Between the Red-Cockaded Woodpecker and Southern Pine Beetle in the Homochitto National Forest: a Geographic Information System Approach

Date: December 1998
Creator: Skordinski, Karen R. (Karen Renee)
Description: Since the introduction of management practices by the Forest Service to stabilize red-cockaded woodpecker (RCW) populations, the number of cavity trees killed by southern pine beetles (SPB) has increased. A model of the landscape ecology of RCW and SPB in the Homochitto National Forest was created using data collected from the Forest Service and Global Atmospherics. The conclusions of the study were that the RCW and SPB utilize the same type of habitat and the stand hazard maps are an accurate means of determining the locations of SPB infestations. The functional heterogeneity maps created for the SPB and RCW would be useful predictors of future occurrences of either species if complete data were obtained.
