Purpose: The purpose of this study was to examine the effects of initial first and second language proficiencies as well as the language of instruction that a student receives on the relationship between native language ability of students who are English language learners (ELLs) and their development of early literacy skills and the second language.
Method: This study investigated the development of early language and literacy skills among Spanish-speaking students in 2 large urban school districts, 1 middle-size urban district, and 1 border district. A total of 1,016 ELLs in kindergarten participated in the study. Students were administered a comprehensive battery of tests in English and Spanish, and classroom observations provided information regarding the Spanish or English language use of the teacher.
Results: Findings from this study suggest that Spanish-speaking students with high Spanish letter name and sound knowledge tend to show high levels of English letter name and sound knowledge. ELLs with low Spanish and English letter name and sound knowledge tend to show high levels of English letter name and sound knowledge when they are instructed in English. Letter name and sound identification skills are fairly highly positively correlated across languages in the beginning of the kindergarten year. In addition, phonological awareness skills appear to be the area with the most significant and direct transfer of knowledge, and language skills do not appear to be a factor in the development of phonological awareness. Finally, the relationship between oral language skills across languages was low, suggesting little relationship between oral language skills across languages at the beginning of the kindergarten year.
Implications For Practice: Results from this study suggest that pedagogical decisions for ELLs should not only consider effective instructional literacy strategies but also acknowledge that the language of instruction for Spanish-speaking ELLs may produce varying results for different students.

Chronic exposure to traffic noise is associated with increased stress and sleep disruptions. Research on the health consequences of environmental noise, specifically traffic noise, has primarily been conducted in high-income countries (HICs), which have guided the development of noise regulations. The relevance of these findings to policy frameworks in low- and middle-income countries (LMICs) remains uncertain.

This letter proposed a sparse deconvolution localization method (FFT-L1ML2) driven by non-convex L1-αL2 regularization that more closely approximates the ideal L0 norm. It is an alternative that explores the sparse structure of sound sources to enhance localization accuracy, while the original sparse deconvolution beamforming lacks a sufficiently accurate sparse description. An optimization solver composed of forward gradient descent and backward proximal operator is then developed for the FFT-L1ML2 model to reconstruct the beamforming map.

Cochlear implantation is a well-established method for restoring hearing sensation in individuals with severe to profound hearing loss. It significantly improves verbal communication for many users, despite substantial variability in patients' reports and performance on speech perception tests and quality-of-life outcome measures. Such variability in outcome measures remains several years after implantation and could reflect difficulties in attentional regulation.

Much brain imaging work has underscored the functional connections among the inferior frontal gyrus (IFG; articulation), supramarginal gyrus (SMG; letter-sound correspondence), superior temporal gyrus (STG; sound) and fusiform gyrus (FFG; print) during basic reading processes. This reading network supports and coordinates the complex processes that contribute to successful reading. In line with the Hebbian notion that 'neurons that fire together, wire together' we examined cortical thickness among these regions and the extent to which these regions showed structural relationships in average and impaired readers.

Noise pollution has become an important type of environmental pollution, especially in populated areas, due to changes in transportation preferences and industry development. The World Health Organization reports that noise, along with air and water pollution, poses one of the most dangerous pollution threats in big cities. In this study, noise pollution measurements were carried in two different regions of a major city, focusing on sensitive points such as hospitals and schools.
