This study compared reading and mathematics growth trajectories in a statewide dataset of 33,715 students across third through fifth grades. Specifically, we examined growth for English Learners (ELs) who were reclassified as no longer needing English Language services at different grade levels as compared to their never-EL peers. Overall, EL students performed significantly below never-EL students on reading and mathematics assessments at Grade 3, with EL students making greater academic gains across time points than never-EL students. Students who were reclassified after third grade and after fourth grade closed, or began to close, the academic opportunity gap by the end of fifth grade, providing promising evidence suggesting that reclassification policies are adequate for identifying those students who no longer need EL services. Students who continued to be classified as EL from third through fifth grades continued to score significantly lower than never-ELs, and in many cases other EL groups, indicating that there exists a group of EL students who continue to make inadequate reading and mathematics gains across late elementary school. Implications for policy and practices that support EL students' mathematics and reading growth are discussed.

Descartes' systematic physics had little to do with his quantitative accounts of natural phenomena. The former was metaphysical and was concerned with uncovering the causes operating in nature, while the latter dealt with establishing mathematical relations between various natural quantities. I reconstruct a dominant interpretation in recent literature which argues that the two practices are autonomous, and that quantitative problem-solving is normatively subordinated to metaphysical physics.

Natural single-chain nanoparticles (SCNPs) such as proteins have inspired research into the formation and application of synthetic SCNPs. Although the latter can mimic general aspects of the self-assembly behavior of their biological counterparts, these systems remain relatively understudied. In this respect, a systematic series of amphiphilic statistical copolymers (ASC) of different molecular weights, with a hydrophilic comonomer (methacrylic acid) and varying hydrophobic comonomer to encompass methacrylates of different hydrophobicity, are synthesized.

Background: Missing observations within the univariate time series are common in real-life and cause analytical problems in the flow of the analysis. Imputation of missing values is an inevitable step in every incomplete univariate time series. Most of the existing studies focus on comparing the distributions of imputed data.

Objectives: We aimed to study the association between early-onset neonatal infection in near-term and term children and school performance based on mandatory tests in reading and mathematics.
Methods: We conducted a nationwide register-based cohort study including all Danish near-term and term singletons born from 1997 to 2009. Early-onset infection was defined as an invasive bacterial infection during the first week of life.

BACKGROUND Patient monitoring systems (PMSs) are essential for monitoring and managing the condition of critically ill patients. In low-resource settings, limited access to technology, low-level digital literacy, and power outage challenges are usability concerns. The main aim of this study was to evaluate the usability of the IMPALA (Innovative Monitoring in Paediatrics in Low-resource settings: an Aid to save lives) PMS optimized for use in low-resource settings by assessing the opinions and experiences of 24 healthcare professionals.
