The MS-FNO demonstrated robustness in localizing and quantifying stiffness loss, with tolerable errors attributed to experimental noise and model simplifications.

A mapping relationship between material damage and component damage is established to facilitate practical engineering applications. The proposed method is applied to a 5-story, 4-span RC frame, followed by seismic fragility analysis of undamaged and damaged frames.

The purpose of this multilevel phenomenological qualitative study was to explore the assets, unique needs, and resources of rural-residing ADRD caregivers from the caregiver, provider, and policy influencers' perspectives. The study took place between 2019 through 2021 in northern Arizona, a largely rural and geographically vast area home to caregivers from diverse backgrounds. Twenty-seven caregivers to a loved one with ADRD participated in focus groups. Twelve health and social services providers and twelve policy influencers, those involved in leadership positions for aging programs or advocacy groups, completed individual interviews. Caregivers demonstrate many assets which contribute to their ability to manage and cope with their caregiving role. However, caregivers face a series of issues related to their caregiving role and need early and ongoing education regarding ADRD. There is a lack of resources available in rural areas, in particular providers, making it challenging to obtain needed resources necessary to support their loved one with ADRD. Furthermore, there is a need for more providers trained in working with aging adults and those experiencing ADRD, and a need for more culturally relevant resources.</p>","PeriodicalId":51387,"journal":{"name":"Qualitative Report","volume":"27 10","pages":"2343-2358"},"PeriodicalIF":1.1,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9682982/pdf/nihms-1851374.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40706420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
