Frames Of Error: Three Behavioral Approaches To Reducing Stigma Towards People With Disabilities, Rocco Giovanni Catrone

Dissertations

What makes a person disabled is a much-debated topic with some focusing on the individuals impairments (putting the onus of disability on the individual) while others focus on how the environment (both architectural and social) exacerbates an individual’s impairments and creates the conceptualization of disability (putting the onus of disability on society). No matter how a person with a disability (PWD) is categorized, they are met with healthcare, education, and work disparities that are perpetuated both unintentionally and intentionally. This paper examines the various ways disability and subsequently stigma arises from a variety of viewpoints both within and outside the …

An Intensive Longitudinal Functional Lineary Model With Multiple Time Scales, Mostafa Zahed Dec 2020

An Intensive Longitudinal Functional Lineary Model With Multiple Time Scales, Mostafa Zahed

Dissertations

In this study an intensive longitudinal functional model with multiple time-varying scales with scalar outcome, multiple functional predictors, one or more scalar covariates and subject-specific random intercepts through mixed model equivalence was proposed. The framework consists of estimating a time-varying coefficient function that is modeled as a linear combination of time-invariant functions with time-varying coefficients. The model uses information structure of the penalty, while the estimation procedure exploits the equivalence between penalized least squares estimation and a linear mixed model representation. The process is empirically evaluated with several simulations. The simulation suggested that as the sample size and level of …
