The purpose of this dissertation was to gain new insight into video game playing, exposure, and preferences as well as perceptions toward success with computers between students in computer related disciplines (CRD) and students in non computer related disciplines (NCRD). Perceptions toward success with computers were measured using a slightly…

We develop a variational theory of hot nuclear matter in neutron stars and supernovae. It can also be used to study charged, hot nuclear matter which may be produced in heavy-ion collisions. This theory is a generalization of the variational theory of cold nuclear and neutron star matter based on realistic models of nuclear forces and pair…

The purpose of this study was to investigate whether any statistically significant differences in mathematics and reading academic achievement and academic gains of male and female students taught in single-sex classes existed when compared to male and female students taught in coeducational classes. This study reported findings from mathematics…

Many factors that contribute towards the perception of second language (L2) sounds and the subsequent establishment of L2 phonetic categories have been the focus of past research. However, learning a third language, unlike SLA, may be influenced by additional factors attributed to the presence of two language systems in a bilingual instead of one…

According to Gilroy (2007) individuals with learning disabilities (LD) represent the fastest growing population of disabled college students. The purpose of this qualitative study was to investigate and to report the types of support services offered to LD students enrolled in four Western Pennsylvania universities. The researcher conducted…

This empirical study evaluates the document category prediction effectiveness of Naive Bayes (NB) and K-Nearest Neighbor (KNN) classifier treatments built from different feature selection and machine learning settings and trained and tested against textual corpora of 2300 Gang-Of-Four (GOF) design pattern documents. Analysis of the experiment's…

The purpose of this study was to investigate teachers' perceptions use of a state developed educational portal. The research evaluated the differences in the quality, usefulness, and relevance of learning objects found on the website based on teachers' gender and grade level they taught. Grade level taught referred to those grades that are the…

The career development and decision-making process of student-athletes has been found to be a complex process (Brown, Glastetter-Fender, & Shelton, 2000; Lally & Kerr, 2005; and Sandstedt, Cox, Martens, Ward, Webber, & Ivey, 2004). Intertwined with issues not found within the general student population career development and decision-making…

Evidence indicates that after-school programs are beneficial to children in the elementary school years, especially when they target more than just problem behaviors, but also focus on a wide range of positive developmental outcomes such as critical thinking, self-awareness and self-confidence (Catalano et al., 2002). The most effective programs…

In light of continuing educational reform and the increased focus on student achievement, school districts, states, and other constituents involved in preparing K-12 public school teachers have increasingly come under scrutiny as to how they have been and are continuing to prepare future educators. One area that has garnered increased attention is…

We establish an isoperimetric inequality for the fundamental tone (first nonzero eigenvalue) of the free plate of a given area, proving the ball is maximal. Given tau greater than 0, the free plate eigenvalues omega and eigenfunctions upsilon are determined by the equation Delta Delta upsilon - tau Delta upsilon = omega upsilon together with…

The graphic rating scale, a measurement tool used in many areas of psychology, usually takes a form of a fixed-length line segment, with both ends bounded and labeled as extreme responses. The raters mark somewhere on the line, and the length of the line segment from one endpoint to the mark is taken as the measure. An item response unfolding…

The soybean cyst nematode (SCN), "Heterodera glycines" is an obligate plant parasite that can cause devastating crop losses. To aide in the study of this pathogen, the SCN genome and the transcriptome of second stage juveniles and eggs were shotgun sequenced. A bioinformatic screen of the data revealed nine genes involved in the "de novo"…

This study focuses on the analysis of the behavior of unbound aggregates to offset wheel loads. Test data from full-scale aircraft gear loading conducted at the National Airport Pavement Test Facility (NAPTF) by the Federal Aviation Administration (FAA) are used to investigate the effects of wander (offset loads) on the deformation behavior of…

Methanogens are strictly anaerobic Archaea that derive their energy for growth by reducing a limited number of substrates to methane. "Methanosarcina" spp. utilize the methylotrophic pathway to grow on methanol, methylamines and methylsulfides. These compounds enter the methylotrophic pathway as methyl-coenzyme M, the synthesis of which is…
