Authentic Representations of Youth Who Stutter: An Analysis of Children\u27s and Adolescent Literature
This analysis seeks to explore the way in which characters who stutter are portrayed in children’s and adolescent literature. Using Joan Blaska’s criteria for reviewing depictions of characters with disabilities, I consider eight texts in how affectively they present the disability of stuttering and their main character. The eight texts considered include picture books, graphic novels, and traditional novels all centering on the story of a main character who stutters were considered. Four of these books are designed for ages four to twelve and are analyzed as children’s literature and the other four are written for ages eleven to eighteen and are analyzed as adolescent literature. The authors of these books include career authors, speech pathologists, and people who stutter or previously stuttered. The essay seeks to provide an overview of stuttering and disability representation in literature as well as to identify common themes across texts
The effects of head posturing on the voice and listeners' perception of masculinity
PURPOSE: The purpose of this study was to investigate the impact of head position on unfamiliar listeners’ perception of vocal masculinity.
METHOD: Twelve cisgender women were recruited as speaking participants in this study. Participants were recorded reciting two voiced sentences at eight time points with varying head positions including baseline, flexed, and extended. Voice samples were cropped and fundamental frequency (fo) was resynthesized to control for any changes in fo across conditions. Twelve cisgender adults were recruited as listening participants. Listeners were presented with 144 paired comparisons of speaker samples and were prompted to select the sample that sounded more masculine in each presented pairing. Ratings of masculinity were analyzed using Thurstone’s law of comparative judgment. A repeated measures one-way analysis of variance (ANOVA) was used to assess the effect of head positioning and repetition, followed by Dunnett’s post hoc tests for significant factors.
RESULTS: The ANOVA showed a statistically significant effect of head position on listener perceptions of masculinity. Dunnett’s post hoc tests revealed a statistically significant effect of the flexed position and no statistically significant effect of the extended compared to the neutral condition.
CONCLUSION: Speakers’ voices in the flexed head position were perceived as most masculine by unfamiliar listeners. Overall, the results of this study support the use of head posture manipulation to achieve increased vocal masculinity, which adds to the limited research related to voice masculinization strategies for those seeking gender-affirming voice care
Projected resurgence of COVID-19 in the United States in July—December 2021 resulting from the increased transmissibility of the Delta variant and faltering vaccination
In Spring 2021, the highly transmissible SARS-CoV-2 Delta variant began to cause increases in cases, hospitalizations, and deaths in parts of the United States. At the time, with slowed vaccination uptake, this novel variant was expected to increase the risk of pandemic resurgence in the US in summer and fall 2021. As part of the COVID-19 Scenario Modeling Hub, an ensemble of nine mechanistic models produced 6-month scenario projections for July–December 2021 for the United States. These projections estimated substantial resurgences of COVID-19 across the US resulting from the more transmissible Delta variant, projected to occur across most of the US, coinciding with school and business reopening. The scenarios revealed that reaching higher vaccine coverage in July–December 2021 reduced the size and duration of the projected resurgence substantially, with the expected impacts was largely concentrated in a subset of states with lower vaccination coverage. Despite accurate projection of COVID-19 surges occurring and timing, the magnitude was substantially underestimated 2021 by the models compared with the of the reported cases, hospitalizations, and deaths occurring during July–December, highlighting the continued challenges to predict the evolving COVID-19 pandemic. Vaccination uptake remains critical to limiting transmission and disease, particularly in states with lower vaccination coverage. Higher vaccination goals at the onset of the surge of the new variant were estimated to avert over 1.5 million cases and 21,000 deaths, although may have had even greater impacts, considering the underestimated resurgence magnitude from the model
Impact of SARS-CoV-2 vaccination of children ages 5–11 years on COVID-19 disease burden and resilience to new variants in the United States, November 2021–March 2022: a multi-model studyResearch in context
Summary: Background: The COVID-19 Scenario Modeling Hub convened nine modeling teams to project the impact of expanding SARS-CoV-2 vaccination to children aged 5–11 years on COVID-19 burden and resilience against variant strains. Methods: Teams contributed state- and national-level weekly projections of cases, hospitalizations, and deaths in the United States from September 12, 2021 to March 12, 2022. Four scenarios covered all combinations of 1) vaccination (or not) of children aged 5–11 years (starting November 1, 2021), and 2) emergence (or not) of a variant more transmissible than the Delta variant (emerging November 15, 2021). Individual team projections were linearly pooled. The effect of childhood vaccination on overall and age-specific outcomes was estimated using meta-analyses. Findings: Assuming that a new variant would not emerge, all-age COVID-19 outcomes were projected to decrease nationally through mid-March 2022. In this setting, vaccination of children 5–11 years old was associated with reductions in projections for all-age cumulative cases (7.2%, mean incidence ratio [IR] 0.928, 95% confidence interval [CI] 0.880–0.977), hospitalizations (8.7%, mean IR 0.913, 95% CI 0.834–0.992), and deaths (9.2%, mean IR 0.908, 95% CI 0.797–1.020) compared with scenarios without childhood vaccination. Vaccine benefits increased for scenarios including a hypothesized more transmissible variant, assuming similar vaccine effectiveness. Projected relative reductions in cumulative outcomes were larger for children than for the entire population. State-level variation was observed. Interpretation: Given the scenario assumptions (defined before the emergence of Omicron), expanding vaccination to children 5–11 years old would provide measurable direct benefits, as well as indirect benefits to the all-age U.S. population, including resilience to more transmissible variants.

Evaluation of the US COVID-19 Scenario Modeling Hub for informing pandemic response under uncertainty
Abstract Our ability to forecast epidemics far into the future is constrained by the many complexities of disease systems. Realistic longer-term projections may, however, be possible under well-defined scenarios that specify the future state of critical epidemic drivers. Since December 2020, the U.S. COVID-19 Scenario Modeling Hub (SMH) has convened multiple modeling teams to make months ahead projections of SARS-CoV-2 burden, totaling nearly 1.8 million national and state-level projections. Here, we find SMH performance varied widely as a function of both scenario validity and model calibration. We show scenarios remained close to reality for 22 weeks on average before the arrival of unanticipated SARS-CoV-2 variants invalidated key assumptions. An ensemble of participating models that preserved variation between models (using the linear opinion pool method) was consistently more reliable than any single model in periods of valid scenario assumptions, while projection interval coverage was near target levels. SMH projections were used to guide pandemic response, illustrating the value of collaborative hubs for longer-term scenario projections
