The purpose of this study employing meta-analysis was to assess the impact that after-school programs have on reading and mathematics outcomes. The participants in the primary studies were students in Grades K through 8; years 200 through 2009. The study utilized the theory of change as its theoretical basis. This meta-analysis used the effect size as the standard measure. It began with an overall Cohen's d of .40 for the impact that after-school programs have on reading and mathematics outcomes, and then proceeded to analyze three moderator variables: subject, time periods, and grade level.The findings of the meta-analysis, both overall and sub analyses, show that the independent variable, after-school programs, has an impact on the dependent variable, reading and mathematics. The overall results indicated that after-school programs are educationally significant in the areas of reading and mathematics combined. As for the moderator variable, the results for the areas of (a) subject (reading and mathematics), (b) time period (2000-2002, 2003-2005 and 2006-2009), and (c) grade (middle, and middle plus elementary combined), all indicated educationally significant results. The notable exception was the grade moderator, elementary.This study provides more information for researchers, practitioners and policy makers upon which to make practical research based decisions about after-school programs for the purpose of determining the applicability of such in their educational setting.

Title: Evaluation of body composition analysis using anthropometric measurements and methods based on bioimpedance Aims: The main goal of this study is to analyze correlations of the data from bioimpedance with direct anthropometric measurements using statistical data analysis taking into consideration that the latter data is recognized as a gold standard. Methods: The sample of 42 men and 20 women was evaluated using standard anthropometric techniques. In addition, the dimensions, which are necessary to establish the weight of segments in upper and lower arms. The obtained data was firstly evaluated using a universal software ANTROPO. The both samples were concurrently investigated using the bioimpedance methods and the relationships between the aforementioned data and data from InBody was evaluated by three independent statistical methods such as substantive significance (Cohen's d), two-parameter linear regression and robust Passing- Bablok regression. Results: The results obtained enable to conclude that (with the exception of body height and BMI) the remaining parameters do not sufficiently correlate when using anthropometric measurements and data from InBody. As the relatively low number of participants may result in certain misrepresentation of the results, particularly in women, the...

The thesis deals with language ideologies in Czech public discourse. After introducing its topic, motivation and structure in the opening chapter, it devotes the second chapter to a thorough analysis of the research field of language ideologies. It presents various ways of defining them, two different approaches to them and a few key features which characterize language ideologies. The relation of language ideologies and other related notions is outlined, possibilities and ways of investigation are surveyed. Some remarks focus on existing lists or glossaries of language ideologies. The core of this chapter is an original, complex definition of language ideologies grounded in a critical reflection of approaches up to now. The third chapter summarizes relevant existing findings and on that basis, it formulates the main aim of the thesis - to make a contribution to knowledge on the foundations and ways of conceptualizing language in Czech public discourse. The fourth chapter elaborates the methodological frame of the thesis. Critical discourse analysis is chosen as a basis - its basics are summarized, main critical comments are considered and a partial solutions are proposed in use of corpus linguistics' tools. Another part of this chapter concerns with keyness as one of the dominant principles used...
