Don’t You Be Telling Me How Tah Talk: Education, Ebonics, and Code-switching

Ebonics, currently referred to as African-American English (AAE), is a highly-controversial topic inside and outside of the classroom. Many educators, scholars, and legislators debate how teachers should approach students who speak AAE and how they can fill the gap between African-American English and Standard English in a way that disbands the dialectal prejudices that may exist. This thesis focuses on code-switching as a pedagogical tool to help teachers instruct Black students in mastering Standard English on a proficient level, particularly Black students who speak AAE. This study explores current problems and practices in the way that English teachers approach AAE while attempting to provide a solution to this problem. This study includes various scholarly articles, information from Education Departments from Michigan, California, and Mississippi, and books from AAE scholars, such as Dr. William Labov, Geneva Smitherman, John Baugh, and Dr. Robert Williams

The Feasibility of the Disturbance Accommodating Controller for Precision Antenna Pointing

The objective of this study is to investigate the feasibility of a pointing (position loop) controller for the NASA-JPL Deep Space Network (DSN) antennas using the Disturbance Accommodating Control (DAC) theory. A model that includes state dependent disturbances was developed, and an example demonstrating the noise estimator is presented as an initial phase in the controller design. The goal is to improve pointing accuracy by the removal of the systematic errors caused by the antenna misalignment as well as sensor noise and random wind and thermal disturbances. Preliminary simulation results show that the DAC technique is successful in both cancelling the imposed errors and maintaining an optimal control policy

Forward with Dementia: process evaluation of an Australian campaign to improve post-diagnostic support

Background: Forward with Dementia is a co-designed campaign to improve communication of dementia diagnosis and post-diagnostic support. Methods: Webinars, a website, social and traditional media, and promotions through project partners were used to disseminate campaign messages to health and social care professionals (primary audience) and people with dementia and carers (secondary audience). The campaign ran between October 2021 and June 2022, with 3-months follow-up. The RE-AIM framework was used for process evaluation. Measurements included surveys and interviews, a log of activities (e.g. webinars, social media posts) and engagements (e.g. attendees, reactions to posts), and Google Analytics. Results: There were 29,053 interactions with campaign activities. More than three-quarters of professionals (n = 63/81) thought webinars were very or extremely helpful. Professionals and people with dementia and carers reported that the website provided appropriate content, an approachable tone, and was easy to use. Following campaign engagement, professionals planned to (n = 77/80) or had modified (n = 29/44) how they communicated the diagnosis and/or provided post-diagnostic information and referrals. Qualitative data suggested that the campaign may have led to benefits for some people with dementia and carers. Conclusions: Forward with Dementia was successful in terms of reach, appropriateness, adoption and maintenance for professionals, however flow-through impacts on people with dementia are not clear. Targeted campaigns can potentially change health professionals’ communication and support around chronic diseases such as dementia

A large genome-wide association study of age-related macular degeneration highlights contributions of rare and common variants

Advanced age-related macular degeneration (AMD) is the leading cause of blindness in the elderly with limited therapeutic options. Here, we report on a study of \u3e12 million variants including 163,714 directly genotyped, most rare, protein-altering variant. Analyzing 16,144 patients and 17,832 controls, we identify 52 independently associated common and rare variants (P \u3c 5×10–8) distributed across 34 loci. While wet and dry AMD subtypes exhibit predominantly shared genetics, we identify the first signal specific to wet AMD, near MMP9 (difference-P = 4.1×10–10). Very rare coding variants (frequency \u3c 0.1%) in CFH, CFI, and TIMP3 suggest causal roles for these genes, as does a splice variant in SLC16A8. Our results support the hypothesis that rare coding variants can pinpoint causal genes within known genetic loci and illustrate that applying the approach systematically to detect new loci requires extremely large sample sizes

Improving procedural fidelity of behavioural interventions for people with intellectual and developmental disabilities: A systematic review

Background: Despite its importance within behavioural intervention, it remains unclear how best to achieve high procedural fidelity. This paper reviewed studies on improving procedural fidelity of behavioural interventions for individuals with intellectual and developmental disabilities (IDD). Method: A systematic literature search was conducted, which identified 20 studies meeting inclusion criteria. Data were extracted on study design, participant characteristics, intervention, target behaviours, effect sizes, maintenance, generalisation, and social validity. A quality rating was also applied. Results: A total of 100 participants took part in the included studies. Most participants were teachers working with children in school settings. There was a significant positive correlation between level of procedural fidelity and client outcomes. Feedback was the most commonly employed intervention to improve procedural fidelity. Conclusions: More research should be conducted in environments with high levels of variability such as community homes to determine how to reach and maintain high levels of procedural fidelity
