Native American Indian Female Students In Higher Education, Becky Youngbear Jan 1998

Native American Indian Female Students In Higher Education, Becky Youngbear

Graduate Research Papers

Colleges and universities have witnessed a significant increase in the number of underrepresented student populations but are just beginning to become aware of their needs. These students encounter academic and social problems prior to and after entering colleges and universities. Institutional awareness and support are just a start in an effort to retain and assist underrepresented students in college. Among these underrepresented groups are Native American Indians who are challenged to succeed in a Eurocentric higher education setting.

Instructional Technology In The School System, Sherri Sue Zanotti Jan 1998

Instructional Technology In The School System, Sherri Sue Zanotti

Graduate Research Papers

Analyses of the deployment of technology in schools have tended to note its failure to affect the daily values and practices of teachers and students. This absence is generally regarded as an implementation failure, or as resulting from some temperamental shortcoming on the part of the teachers or technologists. Such a construction is predicated on the assumption that the technology is value free and its implementation a struggling playing field. This paper proposes that no instructional technology is ever neutral. Its value and practices must support the organization into which it is placed. The failures of technology to look and …

Classroom Discussion: A Journey To Decentralizing The Classroom, Mike Suther Jan 1998

Classroom Discussion: A Journey To Decentralizing The Classroom, Mike Suther

Graduate Research Papers

Throughout history of the United States, teachers have instigated classroom discussion about text in hopes that talk enhanced understanding. More recently, Vygotsky (1978) produced evidence of the importance of social talk in learning. It is through this social interaction or discussion that students construct and negotiate meaning of text. What constitutes social interaction or discussion is what leads some teachers to disagree. The literature on discussion has classified it into two types: recitation and discussion.

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The presence of dissolved organic matter (DOM) in a wastewater treatment system can significantly affect the uptake of heavy metals by sludge particulates. The characteristics of DOM, its concentration, and the solution pH are important parameters governing the heavy metals uptake reaction. The characteristics of DOM of various wastewater and sludge (primary, secondary, and tertiary) samples collected from four municipal wastewater treatment plants were investigated. Results showed that the dissolution of DOM from sludge is significantly affected by pH and suspended solids concentration. Results also showed that DOM contains two discrete acid groups that are available for metals complexation. The …

Growth Traits Among Sorghum Genotypes In Response To Aluminum, J. H. Bernal, R. B. Clark Jan 1998

Growth Traits Among Sorghum Genotypes In Response To Aluminum, J. H. Bernal, R. B. Clark

Department of Agronomy and Horticulture: Faculty Publications

Aluminum (Al) has many detrimental effects on plant growth, and shoots and roots are normally affected differently. A study was conducted to determine differences among sorghum [Sorghum bicolor (L.) Moench] genotypes with broad genetic backgrounds for growth traits of plants grown at 0,200,400,600, and 800 uM Al in nutrient solutions (pH 4.0). Genotypes were categorized into "Al-sensitive", "intermediate Al-tolerant", "Al-tolerant", and SC 283 (an Al-tolerant standard). As Al increased, shoot and root dry matter (DM), net main axis root length (NMARL), and total root length (TRL) became lower than controls (0 Al). Aluminum toxicity and/or nutrient deficiency symptoms become …

Genetic Algorithm Development For Multiobjective Optimization Of Structures, Franklin Y. Cheng, Dan Li Jan 1998

Genetic Algorithm Development For Multiobjective Optimization Of Structures, Franklin Y. Cheng, Dan Li

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Genetic algorithms (GAs) have the characteristic of maintaing a population of solutions and can search in a parallel manner for many nondominated solutions. These features coincide with the requirement of seeking a Pareto optimal set in a multiobjective (multicriteria, vector) optimization problem. The retionale for multiobjective optimization via GAs is that at each generation, the fitness of each individual is defined according to its nondominated property. Because nondominated individuals are assigned the highest fitness values, the convergence of a population will go th the nondominated zone: the Pareto optimal set. Based on this concept, a Pareto, GA, whose goal is …

Contribution Of Externally Bonded Frp To Shear Capacity Of Rc Flexural Members, Ahmed Khalifa, William J. Gold, Antonio Nanni, M. I. Abdel Aziz

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Fiber reinforced polymer (FRP) materials are continuing to show great promise for use in strengthening reinforced concrete structures. These materials are an excellent option for use as external reinforcing because of their light weight, resistance to corrosion, and high strength. Externally bonded FRP sheets have been used to increase moment capacity of flexural members and to improve confinement in compression members. Investigations into the use of externally bonded FRP sheets for shear strengthening have also been conducted and have been shown to be viable. The objectives of this study were to review the current research on shear strengthening with FRP …

Optimizing Multiagent, Multi-Injected Swell Modifier, Marshall B. Addison, Thomas M. Petry

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Interactions of expansive clay soils with transportation facilities have caused billions of dollars of damage. In the process of determining agents and methodologies to overcome expansive clay behavior, multiple injections of chemical agents into the subgrade to modify clay behavior are most promising. A study was conducted to optimize a potassium-rich solution of four parts. The modifying solution has been injected into expansive clay subgrades with success since the early 1970s. A laboratory methodology was developed to inject specimens multiple times and to conduct swell tests. Screening tests were conducted to evaluate linear effects that each of the four constituents …
