Diversas técnicas têm sido propostas para a análise de diagnóstico nesses modelos. O objetivo deste trabalho é apresentar algumas das técnicas de diagnóstico disponíveis para os dois tipos de modelos e avaliá-las por meio de estudos de simulação. As técnicas apresentadas também foram aplicadas em um conjunto de dados reais. / Conditional and marginal models are among the possibilities in statistical literature to analyze data from studies with correlated observations. Several techniques have been proposed for diagnostic analysis in these models. The objective of this work is to present some of the diagnostic techniques available for both modeling approaches and to evaluate them by simulation studies. The presented techniques were also applied in a real dataset. equações de estimação generalizadas medidas repetidas modelos condicionais modelos lineares generalizados mistos modelos lineares mistos modelos marginais técnicas de diagnóstico conditional models diagnostic techniques generalized estimating equations generalized linear mixed models hierarchical generalized linear models linear mixed models marginal models repeated measures
72	Using a Repeated Measures ANOVA Design to Analyze the Effect Writing in Mathematics Has on the Mathematics Achievement of Third Grade English Language Learners and English Speakers Morales, Zoe A 07 November 2016 (has links) The gap that exists between English language learners and English speaking students’ achievement in mathematics continues to grow. Moreover, students are now required to show evidence of their mathematics knowledge through writing in standardized assessments and class assignments. The purpose of this study was to analyze students’ writing in mathematics and the metacognitive behaviors they portrayed through their writing as they solved mathematics problems. The instruments included a pretest, two biweekly tests, and a posttest. The writing instruction encompassed students learning to solve problems by using Polya’s four phases of problem solving which was completed in 12 sessions over a period of 6 weeks. Garofalo and Lester’s framework which renamed Polya’s phases into orientation, organization, execution, and verification, was used to look at the metacognitive behaviors students used. The participants included 67 students enrolled in four third grade classes, who were English language learners and English speakers. This research followed a quasi-experimental design, with a treatment group and a control group. A one-way repeated ANOVA was used to analyze the data. The findings showed no significant difference between the mathematics achievement scores of treatment and control. However, growth trends in achievement scores revealed that the treatment group scores were increasing faster than the control group scores across the four tests during the 6-week study. Moreover, significant differences were found between the treatment and the control groups when the problem solving with metacognitive behaviors scores were analyzed. Descriptive statistics showed the frequency of occurrence of each of the problem solving phases increased steadily across the four tests for the students in the treatment group. During the posttest, 100% of treatment group students wrote about metacognitive behaviors they used during the orientation and organization phases, 91.4% wrote about their metacognition for executing the solution, and 80% wrote about the verification process they followed. These findings are useful to education professionals who are interested in creating programs for teaching mathematics at the elementary level that include effective problem solving practices. This evidence-based method may be adopted in school districts with large populations of ELLs in order to assist these students when solving problems in mathematics. mathematics problem solving elementary education metacognitive behaviors writing in mathematics third graders ELLs quasi-experimental design one-way repeated measures ANOVA Curriculum and Instruction Educational Methods Elementary Education Elementary Education and Teaching Science and Mathematics Education
73	Managing Intellectual Property and Licensing: A Study on Cooperative Research Centres Sheen, Peter Bernard January 2005 (has links) This thesis examines the perceived importance by two-tiered management of Cooperative Research Centres (CRCs) for managing a range of intellectual property issues. Fifty survey items are presented to the executive directors and commercialization managers of 62 CRCs. The survey items are categorized under four themes: relationships with collaborators, project management; design and implementation of agreements; and specific licensing issues. An analysis of the data, using a series of independent samples t-tests, repeated measures t-tests, chi-square tests for independence or relatedness and goodness of fit, shows a range of results. There are significant differences between executive directors and commercialization managers on a number of issues. There are particular emphases or trends about certain issues for the whole sample of managers. These findings are compared with text analyses of 23 CRC strategic planning documents. This is done in order to explore any similarity, difference or nuance between what the managers say in response to the survey items, compared with what is stated in the codified policies of the CRCs. While there is a high degree of consistency among certain themes between the two sets of findings, the overall analysis points to the need for the CRCs to have a better understanding and practice of commercialization opportunities, especially through the involvement of third party commercial interests. It is argued that accommodating third party commercialization interests involves the application of an important knowledge economy principle that has an important bearing on the future economic viability and competitiveness of the CRCs.
