Use Of Web-Based Lessons Of Statistical Concepts With Graphics And Animation To Enhance The Effectiveness Of Learning, Lavanya Pillala

Browse all Theses and Dissertations

Statistics is of critical importance to engineers. However, many engineering students struggle to grasp the meaning of statistical concepts and the idiosyncrasies of statistical methodologies. Because of this problem, instructors of statistics are constantly searching for better ways to help students understand statistical concepts. The goal of this project is to design and develop web-based lessons that use graphics and animations to enhance the effectiveness of students' learning of statistical concepts.

Lessons of three important statistical concepts have been developed for this thesis - normal distribution, central limit theorem and confidence & tolerance intervals - following well-recognized instructional design development …

Domain-Specific Core Self-Evaluations And Stressors As Predictors Of Strains, Michael Raymond Hoepf

Browse all Theses and Dissertations

The current study examines the use of a frame-of-reference (FOR) in the evaluation of core self-evaluations, stressors and strains. The study investigates the prediction that using a FOR that matches predictors and outcomes will result in a stronger relationship between the constructs being measured, specifically CSE, stressors, and strains. In addition, the study examines the extent to which following this procedure will add incremental validity after non-contextualized predictors are controlled. The hypotheses in this study were generally supported, although the hypotheses related to the school domain were not supported as strongly as those related to general and work domain. The …

An Improved Genetic Algorithm For Knapsack Problems, Taskiran, Gamze Kilincli

Browse all Theses and Dissertations

In this study, an improved genetic algorithm (GA) is presented to solve the multidimensional 0-1 knapsack problem (MKP). The MKP is a well-known combinatorial optimization problem and has received wide attention from the operations research community for decades. Although recent advances in computing and optimization technologies have made the solution of small and medium size instances possible, this NP-hard problem, in general, still remains one of the challenging problems yet to be solved.

Of the various algorithms developed to solve the MKP, GA seems to be one of the best methods pointed out in the literature. A GA is an …

Impact Of Culture And Age On The Use Of Social Networking Websites, Ramya Reddy Ponnavolu

Browse all Theses and Dissertations

Social networking websites have become very popular amongst people of all ages in recent times. These websites have brought into existence a new form of data - 'User generated content'. Companies everywhere have begun to identify the potential of these sites and have commenced efforts to take advantage of the profitable opportunities available. In spite of all this, it is reasonable to say that the latent possibilities in social networking sites are yet to be fully explored. This is due to the fact that the technology is still young and research on its potential is still ongoing. The current research …
