Background: Literacy is championed as a pathway out of poverty, yet it is vulnerable to the risk circumstances it seeks to mitigate. This study explored the developmental circumstances that gave rise to stark inequalities in reading achievement in Australian children across 6 years of school.
Methods: We used data from : the Longitudinal Study of Australian Children linked to Australia's National Assessment Program-Literacy and Numeracy across school years 3, 5, 7 and 9. Latent class analysis and growth curve modelling (n=4983) were used to identify risk profiles for reading achievement for children (ages 8.2-15.2).
Results: Four distinct profiles were identified: developmentally enabled profile (62% of children); sociodemographic risk profile (25% of children); child development risk profile (11% of children); and sociodemographic and child development (double disadvantage) risk profile (2% of children). Children with a developmentally enabled profile achieved the expected rate of growth of 1.0 year per year of school across years 3, 5, 7 and 9. By comparison, children with sociodemographic and/or child development risk profiles started behind their developmentally enabled peers, and lost ground over time.
Discussion: Across 6 years of school, multiple risk-exposed children lagged behind low risk-exposed children in the order of years of lost gains in reading achievement. The results point to the complex contexts of educational disadvantage and the need for cross-cutting social, health and education policies and coordinated multiagency intervention efforts to break the cycle of educational disadvantage.

Child-directed speech (CDS), which amplifies acoustic and social features of speech during interactions with young children, promotes typical phonetic and language development. In autism, both behavioral and brain data indicate reduced sensitivity to human speech, which predicts absent, decreased, or atypical benefits of exaggerated speech signals such as CDS. This study investigates the impact of exaggerated fundamental frequency (F0) and voice-onset time on the neural processing of speech sounds in 22 Chinese-speaking autistic children aged 2-7 years old with a history of speech delays, compared with 25 typically developing (TD) peers.

Background: Private-part skin diseases (PPSDs) can cause a patient's stigma, which may hinder the early diagnosis of these diseases. Artificial intelligence (AI) is an effective tool to improve the early diagnosis of PPSDs, especially in preventing the deterioration of skin tumors in private parts such as Paget disease. However, to our knowledge, there is currently no research on using AI to identify PPSDs due to the complex backgrounds of the lesion areas and the challenges in data collection.

The association between school students' social background and school achievement is well documented. Recent studies demonstrated that this association might be moderated by the level of cognitive potential. Based on these results, we recruited an elementary school sample ( = 837) and an adolescent sample at the end of their compulsory school time ( = 2100) to investigate whether the associations between students' social background and their academic achievement in math and language arts were moderated by the level of their general cognitive competencies, i.

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.

Despite advancements in antiretroviral therapy (ART) that reduces the viral load to undetectable levels and improve CD4 T cell counts, viral eradication has not been achieved due to HIV-1 persistence in resting CD4 T-cells. We, therefore, characterized the gene, which is essential for HIV-1 replication and pathogenesis, from 20 virologically controlled aging individuals with HIV (HIV) on long-term ART and improved CD4 T-cell counts, with a particular focus on older individuals. Peripheral blood mononuclear cell genomic DNA from HIV were used to amplify gene by polymerase chain reaction followed by nucleotide sequencing and analysis.
