Expectations for Families to Care for Older Adults in the United States: Rapid Scoping Review 2011–2023

open access: yesJournal of Family Theory &Review, EarlyView.
ABSTRACT As the population ages and families become increasingly diverse, more work is needed to understand expectations for families to care for older adults. In this review, we discuss the theoretical frameworks and conceptualizations used to study care expectations, summarize overarching findings about theories of care expectations and corresponding

Deep dialogism, inner voices, and mental health

open access: yesMind &Language, EarlyView.
The idea that cognition involves dialogic interchange between mutually influencing “voices” has long featured in psychology and philosophy. While dialogic structure is most explicit in inner speech, some authors have argued that other types of mental activity can be (or always are) dialogic. We introduce two dimensions of dialogism, strength and depth,

A load estimator based-fast terminal super-twisting control strategy for performance improvement of induction machine system drive

open access: yesJournal of Applied Science and Engineering
In this work, a hybrid control strategy derived from the control literature for induction machines is proposed, where a sliding-mode controller paired with an estimator from the same function is incorporated to provide fast, robust speed regulation while
