For many years, researchers have sought to understand the reading development of deaf and hard of hearing (DHH) students. Guided by prior research on DHH and hearing students, in this study we investigate the hypothesis that for secondary school DHH students enrolled in American Sign Language (ASL)/English bilingual schools for the deaf, academic English proficiency would be a significant predictor of reading comprehension alongside ASL proficiency. Using linear regression, we found statistically significant interaction effects between academic English knowledge and word reading fluency in predicting the reading comprehension scores of the participants. However, ASL remained the strongest and most consistent predictor of reading comprehension within the sample. Findings support a model in which socio-demographic factors, ASL proficiency, and word reading fluency are primary predictors of reading comprehension for secondary DHH students.

Signing systems that attempted to represent spoken language via manual signs – some invented, and some borrowed from natural sign languages – have historically been used in classrooms with deaf children. However, despite decades of research and use of these systems in the classroom, there is little evidence supporting their educational effectiveness. In this paper, the authors argue against the use of signing systems as instructional tools. This argument is based upon research demonstrating that (1) signing systems are less comprehensible to learners who rely upon signs rather than speech, (2) signing systems are used inconsistently by teachers, and (3) signing systems often unintentionally exhibit features of natural signed grammar, leading to input that does not accurately convey spoken languages, which is the original intention of these systems. Instead, the authors advocate for a return to the use of natural signed languages in classrooms educating deaf children, with creative uses of interpretation to provide those students who may prefer or benefit from spoken English with its presence in the classroom. In addition, we note ways in which future research may explore how natural sign languages and deaf adults may benefit the educational experiences of deaf children.

This article explores the available research literature on language development and language interventions among deaf and hard of hearing (d/hh) children. This literature is divided into two broad categories: Research on natural languages (specifically American Sign Language and spoken English) and research on communication systems (specifically iterations of signed English and cued speech). These bodies of literature are summarized, with special attention paid to intervention research and research exploring the impacts of language skills on literacy development. Findings indicate that there is generally a stronger research base on natural languages as compared to communication systems, though more studies in both categories are necessary. Additionally, there are very few intervention studies and even fewer that aim to intervene upon language with the explicit goal of impacting literacy; therefore, there is little known about whether and how interventions that aim to support language development may have direct or indirect impacts on literacy within this population. Further research on this topic, as well as replication studies and research with larger sample sizes, is strongly recommended.

Active transdermal technology, commonly associated with drug delivery, has been used in recent years by the cosmetic industry for the aesthetic restoration of skin and delivery of cosmetic agents. In this article, we provide an overview of the skin's structure, various skin types, skin's self-repair mechanisms that are stimulated from the usage of cosmetic devices and discuss cosmetic applications. Summaries of the most common active transdermal technologies such as microneedles, iontophoresis, sonophoresis, lasers and microdermabrasion will be provided, in relation to the marketed cosmetic devices available that incorporate these technologies. Lastly, we cover combinations of active technologies that allow for more enhanced cosmetic results, and the current limitations of cosmetic devices.

Academic English is an essential literacy skill area for success in post-secondary education and in many work environments. Despite its importance, academic English is understudied with deaf and hard of hearing (DHH) students. Nascent research in this area suggests that academic English, alongside American Sign Language (ASL) fluency, may play an important role in the reading proficiency of DHH students in middle and high school. The current study expands this research to investigate academic English by examining student proficiency with a sub-skill of academic writing called superordinate precision, the taxonomical categorization of a term. Currently there is no research that examines DHH students’ proficiency with superordinate precision. Middle and high school DHH students enrolled in bilingual schools for the deaf were assessed on their ASL proficiency, academic English proficiency, reading comprehension, and use of superordinate precision in definitions writing. Findings indicate that student use of superordinate precision in definitions writing was correlated with ASL proficiency, reading comprehension, and academic English proficiency. It is possible that degree of mastery of superordinate precision may indicate a higher overall level of proficiency with academic English. This may have important implications for assessment of and instruction in academic English literacy.
