Under the STORMTOOLS initiative, maps of the impact of sea level rise (SLR) (0 to 12 ft), nuisance flooding (1–10 yr), 25, 50, and 100 yr storms, and hindcasts of the four top ranked tropical storms have been developed for the coastal waters of Rhode Island (RI). Estimates of the design elevations, expressed in terms of the Base Flood Elevation (BFE) and thus incorporating surge and associated wave conditions, have also been developed, including the effects of SLR to facilitate structural design. Finally, Coastal Environmental Risk Index (CERI) maps have been developed to estimate the risk to individual structures and infrastructure. CERI employs the BFE maps in concert with damage curves for residential and commercial structures to make estimates of damage to individual structures. All maps are available via an ArcGIS Hub. The objective of this senior design capstone project was to develop STORMTOOLS Design Load maps (SDL) with a goal of estimating the hydrostatic, hydrodynamic, wave, and debris loading, based on ASCE/SEI 7–16 Minimum Design Standards methods, on residential structures in the RI coastal floodplain. The resulting maps display the unitized loads and thus can be scaled for any structure of interest. The goal of the maps is to provide environmental loads that support the design of structures, and reduce the time and cost required in performing the design and the permitting process, while also improving the accuracy and consistency of the designs. SDL maps were generated for all loads, including the effects of SLR for a test case: the Watch Hill/Misquamicut Beach, Westerly, along the southern RI coast. The Autodesk Professional Robot Structural Analysis software, along with SDL loading, was used to evaluate the designs for selected on-grade and pile-elevated residential structures. Damage curves were generated for each and shown to be consistent with the US Army Corps of Engineers empirical damage curves currently used in CERI.

- Abstract
Here we describe the generation and characterization of a Cre knock-in mouse line that harbors a Cre insertion in the 3'UTR of the κ opioid receptor gene ( Oprk1 ) locus and provides genetic access to populations of κ opioid receptor (KOR)-expressing neurons throughout the brain. Using a combination of techniques including RNA in situ hybridization and immunohistochemistry, we report that Cre is expressed with high fidelity in KOR-expressing cells throughout the brain in this mouse line. We also provide evidence that Cre insertion does not alter basal KOR function. Baseline anxiety-like behaviors and nociceptive thresholds are unaltered in Oprk1-Cre mice. Chemogenetic activation of KOR-expressing cells in the basolateral amygdala (BLA
KOR cells) resulted in several sex-specific effects on anxiety-like and aversive behaviors. Activation led to decreased anxiety-like behavior on the elevated plus maze and increased sociability in female but not in male Oprk1-Cre mice. Activation of BLAKOR cells also attenuated KOR agonist-induced conditioned place aversion (CPA) in male Oprk1-Cre mice. Overall, these results suggest a potential role for BLAKOR cells in regulating anxiety-like behaviors and KOR-agonist mediated CPA. In summary, these results provide evidence for the utility of the newly generated Oprk1-Cre mice in assessing localization, anatomy, and function of KOR circuits throughout the brain., (Copyright © 2023 Paliarin et al.)- Published

- Abstract
Purpose: Primary progressive aphasia (PPA) is a clinical neurodegenerative dementia syndrome characterized by early, selective, and progressive language impairment. PPA onset is gradual, providing time to potentially identify additional or alternative expressive communication modes; however, reports of communication mode use and effectiveness by persons with PPA have not been described. This study characterized the use, frequency, and perceived effectiveness of communication modes reported by individuals with PPA., Method: Forty-one participants with mild-to-moderate PPA completed a structured interview detailing the type, frequency, and perceived effectiveness of 12 potential communication modes, categorized by technology required (no-tech, low-tech, and high-tech). The ratio of modes used was compared across technology categories with a repeated-measures generalized linear model assuming a binomial distribution with an overall Wald chi-square statistic, followed by pairwise post hoc t -test comparisons., Results: Of the 12 communication modes assessed, participants reported using a median of eight (range: 5-10). All participants affirmed using speech, facial expressions, and talking on the phone. Frequency and perceived effectiveness ratings for these three modes were endorsed at the "some/most of the time" level for more than 80% of the participants. No-tech mode use was significantly higher than reported high-tech and low-tech modes ( p = .004 and p < .0001, respectively). Even so, while some high-tech modes (apps) and some low-tech modes (nonelectronic augmentative and alternative communication) had fewer users, effectiveness ratings were moderate to high for all but one user., Conclusions: Persons with mild-to-moderate language impairment due to PPA report using a range of communication modes with moderate-to-high frequency and perceived effectiveness. These outcomes provide practical information when considering mode refinement or expansion during intervention to maximize communication participation. Barriers to modality use may include low awareness or access, which could be queried by future studies and supported by speech and language interventions., Supplemental Material: https://doi.org/10.23641/asha.21614262.

- Abstract
Objectives: Previous reports established the feasibility of a telehealth model for delivering speech-language therapy via Internet videoconferencing, which connects individuals with primary progressive aphasia (PPA) to an expert speech and language pathologist for treatment. This study reports feasibility of the same telehealth intervention in a larger set of progressive aphasia participants and explores factors potentially influencing functional intervention outcomes., Methods: Participants with PPA or progressive aphasia in the context of a neurodegenerative dementia syndrome and their communication partners were enrolled into an 8-session intervention, with 3 evaluations (baseline, 2 months, and 6 months postenrollment). Half of the participants were randomized into a "check-in" group and received 3-monthly half-hour sessions postintervention. Mixed linear models with post hoc testing and percent change in area under the curve were used to examine communication confidence over time, as well as the influence of check-in sessions and the role of communication partner engagement on communication confidence., Results: Communication confidence improved at the 2-month evaluation and showed no significant decline at the 6-month evaluation. Item-level analysis revealed gains in communication confidence across multiple communication contexts. Gains and maintenance of communication confidence were only present for the engaged communication partner group and were not bolstered by randomization to the check-in group., Discussion: Internet-based, person-centered interventions demonstrate promise as a model for delivering speech-language therapy to individuals living with PPA. Maintenance is possible for at least 6 months postenrollment and is better for those with engaged communication partners, which supports the use of dyadic interventions., (© The Author(s) 2021.

- Abstract
Purpose: The use of telepractice in the field of communication disorders offers an opportunity to provide care for those with primary progressive aphasia (PPA). The Western Aphasia Battery-Revised (WAB-R) is used for differential diagnosis, to assess severity of aphasia, and to identify a language profile of strengths and challenges. Telehealth administration of the WAB-R is supported for those with chronic aphasia due to stroke but has not yet been systematically explored in neurodegenerative dementia syndromes. To fill this gap, in-person and telehealth performance on the WAB-R from participants with mild to moderate PPA was compared., Method: Nineteen participants with mild to moderate PPA were administered the WAB-R in person and over videoconferencing. Videoconferencing administration included modifications to the testing protocol to ensure smooth completion of the assessment. Subtest and Aphasia Quotient (WAB-AQ) summary scores were compared using concordance coefficients to measure the relationship between the administration modes., Results: In-person and telehealth scores showed strong concordance for the WAB-AQ, Auditory Verbal Comprehension subtest, and Naming & Word Finding subtest. The Spontaneous Speech test summary score had slightly lower concordance, indicating the need for caution when comparing these scores across administration modes., Conclusion: These findings support extending the use of telehealth administration of the WAB-R via videoconferencing to those with mild to moderate PPA given appropriate modifications to testing protocol.
