A model is developed and demonstrated for simulating echosounder and sonar observations of fish schools with specified shapes and composed of individuals having specified target strengths and behaviors. The model emulates the performances of actual multi-frequency echosounders and multi-beam echosounders and sonars and generates synthetic echograms of fish schools that can be compared with real...

This study investigates one dimension of personality, extroversion-introversion, and examines its potential impact on learner L2 oral performance. The study is innovative in that it analyzes not only the correlation between degree of extroversion and assessment scores based on analytic scoring but also the correlation between degree of extroversion and the discourse measures of accuracy, fluenc...

Existing research that estimates principals’ effects on student achievement has employed value-added models that have only limited usefulness for actual performance evaluation systems. Principals’ effects are typically identified through school leadership changes, meaning that effectiveness data cannot be generated for all principals and that effects are comparable only within small groups of s...

Selective attention and efficacy are important components of scholastic performance in school children. While attempts are being made to introduce new methods to improve academic performance either as part of curricular or extracurricular activities in schools, the success rates are minimal. Hence, this study assessed the effect of yoga-based intervention on psychomotor performance and self-eff...

This thesis aims at filling this gap. We use experimental and quasi-experimental data and rely on both program evaluation and structural approaches. The thesis is organized in 5 chapters. After introduction in Chapter 1, Chapter 2 uses a quasi-experimental data to assess the impacts of meal and deworming programs taken on isolation. We study the impact of these programs on school performances m...

In this Chapter, we critically review the sizable literature that values school quality and performance through housing valuations. While highly variable in terms of research quality, the literature consistently finds housing valuations to be significantly higher in places where measured school quality is higher. Thus parents are prepared to pay substantial amounts of money to get their childre...

AIM The aims of this study were to determine the relationship between performances of students in clinical skills laboratory and real life clinical practice and to determine the experiences and views of instructors as it relates to teaching in skills laboratory. METHODS The performances of two randomly selected sets of graduates in the operative examinations conducted in skills laboratory wer...

Objective. Many organization theories suggest that divergent goals can hamper an organization’s pursuit of its primary mission. This study analyzes the effect of the pursuit of divergent goals on American public schools. Methods. Using an educational production function, this paper assesses the relationships between athletic budgets and various aggregate measures of academic performance. Result...

BACKGROUND Students' perspective on education is of crucial importance for its effectivity, but students' opinions are seldom acknowledged by teachers and designers. Student participation in the educational design process could be a suitable tool to better take students' preferences into account. However, for effective participatory design, it is necessary to know whether students have stable p...
