The ability of certain RNAs to fold into complicated secondary and tertiary structures provides them with the ability to perform a variety of functions in the cell. Since the secondary and tertiary structures formed by certain RNAs in the cell are central to understanding how they function, one of the most active areas of research has been how to accurately and reliably predict RNA secondary structure from sequence; better known as the RNA Folding Problem. This dissertation examines two fundamental areas of research in RNA structure prediction, free energy minimization and comparative analysis. The most popular RNA secondary structure prediction program, Mfold 3.1 predicts RNA secondary structure via free energy minimization using experimentally determined energy parameters. I present an evaluation of the accuracy of Mfold 3.1 using the largest set of phylogenetically diverse, comparatively predicted RNA secondary structures available. This evaluation will show that despite significant revisions to the energy parameters, the prediction accuracy of Mfold 3.1 is not significantly improved when compared to previous versions. In contrast, RNA comparative analysis has repeatedly demonstrated the ability to accurately and reliably predict RNA secondary structure. The downside is that RNA comparative analysis frequently requires an expert systems methodology which is predominately manual in nature. As a result, RNA comparative analysis is not capable of scaling adequately to be useful in the genomic era. Therefore, I developed the Comparative Analysis Toolkit (CAT) which is intended to be the fundamental component of a vertically integrated software infrastructure to facilitate high-throughput RNA comparative analysis using an expert systems methodology.

With federal gender equity mandates in place, some may assume that schools are now havens were children are protected from discrimination based on failure to conform to stereotypical notions of masculinity and femininity. Yet, research suggests that the school literacy curriculum serves as a site that privileges gender performances consistent with the binary gender order. This pattern has been observed such that school literacy practices reproduce the binary gender order through text, talk, and disciplining of the body. Informed by post structural feminist perspectives on discourse, power, and performativity, this qualitative case study employed feminist methodology to explore how power flowed through performances of gender within the context of one second grade literacy classroom. Data sources included participant observation field notes, informal student and teacher interviews, video and audio recordings, and the collection of literacy related objects/documents. Results of the analysis suggest that there were two distinct literacy spaces within the classroom: the teacher-controlled official literacy space and the student-governed unofficial literacy space. Within the official literacy space, particular teaching moves made at the intersection of gender and literacy could later be linked to particular students’ gender performances. In the unofficial literacy space of the classroom, some students’ gender performances diverged greatly from those they performed in the official literacy space thus making visible how power operates within embodied acts. Lastly, in looking across the two distinct literacy spaces of the classroom, it was revealed how the flow of power through performances of gender and thus, the discursive practices that hold existing gendered structures in place, were more visible in unofficial literacy spaces than in official literacy spaces. Therefore, results of the analysis suggest that looking to unofficial literacy spaces will provide invaluable guidance when reconceptualizing how official literacy spaces might better support gender equity within the early elementary literacy classroom.

Problem. The purpose of this study was to assess the effectiveness of elementary school teachers who had received intensive training in the Essential Elements of Instruction model, a teaching methodology composed of specific teacher behaviors. Teacher effectiveness was measured by analyzing student achievement results in reading. Procedure. Elementary teachers at specified grade levels in two selected school districts were divided into two groups: Group A, teachers who had received training in the Essential Elements of Instruction, and Group B, teachers who had not received this training. In School District I, a student population of approximately two hundred and twenty-five students was selected as the treatment group and a student population of approximately two hundred and ten students was selected as the control group. In School District II, a student population of approximately one hundred and forty-five students was selected as the treatment group and a student population of approximately one hundred and forty students was selected as the control group. The Gates-MacGinitie Reading Test (Form A-E) was used as the post test measure of achievement for all students. This test was used to determine if a teacher's training in the Essential Elements of Instruction model would result in greater student achievement gains as measured by the selected reading test. Results. The analysis of variance treatment of the data indicated that there were significant differences between the reading scores of students whose teachers had received training in the Essential Elements of Instruction model and those students whose teachers did not receive this training. Thus, the data did allow for the rejection of null Hypothesis 1. The analysis of variance treatment of the data indicated that there were no interaction effects of teacher training and student reading achievement by the grade level of the student, the socioeconomic level of the student, or the interaction of student grade level and student socioeconomic level. Thus, the data did not allow for the rejection of null Hypothesis 2, null Hypothesis 3 and null Hypothesis 4.

Mini-dissertation was submitted in partial compliance with the requirements for the Master's Degree in Technology: Homoeopathy, Durban Institute of Technology, 2007. / The first formal Homeopathic education programme in South Africa began in 1989 and was instituted by Technikon Natal, now Durban University of Technology – DUT. The course offers a Master’s Degree in Technology in Homeopathy. Similarly Witwatersrand Technikon now University of Johannesburg began offering the course from 1993. Since the first (from DUT) intake there have been 13 years of graduates. Included in the course is excellent homeopathic training and a comprehensive medical training programme, consisting of anatomy, physiology, pathology, histology and diagnostics subjects. Although a statutory requirement no postgraduate internship training regarding graduates of this programme has been formalised. Thus this study was deemed valuable as it aimed to provide clarity on past internship received and a perception of what an internship ought to entail. The purpose of this retrospective survey was to determine the perceptions and opinions of M.Tech:Homeopathy graduates around the current non-implementation of statutory internship, in order to inform the formulation of an appropriate and effective homoeopathic internship, as required by Act 63 of 1982 (as amended). Other objectives included gathering data/perceptions regarding the contents and outcomes of a proposed Homeopathic internship as perceived by M.Tech:Homeopathy graduates. As well as assessing/determining the possible existence of associations between demographic factors and the perceptions around internship regarding its recommended contents and outcomes. / M

This quantitative, non-experimental study was conducted to investigate the link between school principal influence actions, climate, culture, and school performance. Additionally, this study sought to determine if the influence of these variables or the relationship among them is altered by individual and/or institutional characteristics. The first phase of the study was conducted to determine whether or not the Customer Survey aligned to distinct dimensions. Two factors were identified: Staff Attitudes and Student Disruptions. The second part used regression to examine the relationships among four constructs and test the seven hypotheses. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection
