Exploring Consequences Of The Double Empathy Problem Across The Autistic Trait Spectrum: First Person Accounts, Cammy C. Peck

Theses and Dissertations

Historically, individuals on the autism spectrum were believed to have deficits in empathy. However, recent research suggests that empathy-related issues occur on both sides of the communication dynamic. This concept known as the Double Empathy Problem (DEP), posits that the perceived lack of empathy is not exclusive to autistic individuals; rather, neurotypical (NT) individuals also experience difficulty empathizing with autistic individuals (Milton, 2012). Milton et al. (2022) describes this as a "breakdown in mutual understanding". Such mutual misunderstanding can have adverse consequences for both autistic and neurotypical individuals. To our knowledge, no studies have directly examined these consequences in relation …

Latent Profiles Of Couples' Marital Power And Gender Ideologies: Associations With Physical Intimate Partner Violence, Rylie Speirs

Theses and Dissertations

This study aims to identify couple typologies regarding gender ideologies and marital power, and investigate how couple typologies relate to sociodemographic characteristics as well as rates of physical intimate partner violence (IPV). Several theoretical approaches connect marital power and gender ideologies to IPV but emphasize different couple typologies. For example, family violence perspectives suggest gender ideology mismatch is a stressor that increases the likelihood of either spouse reporting low power or engaging in physical IPV. Feminist theories add that men may use IPV to maintain patriarchal power dynamics when women deviate from traditional gender norms, emphasizing the risk of IPV …

Equiangularity From Compatible Orthobiangularity, Tyler J. Myers

Theses and Dissertations

An equiangular tight frame (ETF) is an equal norm sequence of vectors in a Hilbert space whose coherence achieves equality in the Welch bound. Such sequences necessarily have minimal coherence and thus are, in some sense, as "spread out" in space as possible. ETFs have a variety of applications, such as compressed sensing and waveform design. The main problem in the study of ETFs is determining the pairs (D, N) for which an ETF with N vectors in a D-dimensional space exists. Real ETFs are moreover equivalent to a special subset of a well-studied class of graphs known as strongly …
