Analyses examined academic achievement data across third through eighth grades (N = 26,474), comparing students identified as homeless or highly mobile (HHM) with other students in the federal free meal program (FM), reduced price meals (RM), or neither (General). Achievement was lower as a function of rising risk status (General > RM > FM > HHM). Achievement gaps appeared stable or widened bet...

This paper proposes an improved evolutionary algorithm with parallel evaluation strategy (EAPES) for solving constrained multi-objective optimization problems (CMOPs) efficiently. EAPES stores feasible solutions and infeasible solution separately in different populations, and evaluates infeasible solutions in an unusual manner, such that not only feasible solutions but also useful infeasible so...

The goal of this study was to explore longitudinal associations between peer victimization and academic achievement in Chinese children. Participants were N = 805 3rd-grade students (486 boys, 319 girls; M(age) = 9.5 years, SD = 3 months) attending primary schools in Shanghai, People's Republic of China. At Time 1 and Time 2 (2 years later), peers nominated classmates who were victims of peer m...

BACKGROUND Most developmental disorders are defined by an achievement discrepancy in which achievement on one or more specific abilities is substantially less than a person's measured intelligence. We evaluated the validity of this discrepancy criterion by assessing parameters that determine variability across abilities and by assessing relationships between achievement discrepancies and behavi...

Abstract Students’ prior achievements in school have significant correlations with their later achievements. Specifically, students’ numeracy achievement is the most important predictor of success. However, assessment this across gender and its trend year levels often overlooked or not adequately investigated. This study examined relationships between influence on gender. A focus level also sup...
