“The Goal Is To Help The Community”: Motivations And Experiences Of Diverse Families In A Special Education Parent Advocacy Program, Diana Cruz

Dissertations

The Individuals with Disabilities Education Act (IDEA, 2004) entitles parents of eligible students with disabilities to meaningful participation in their children’s educational planning. Despite this mandate, many parents encountered barriers that limited their ability to participate in special education processes. These challenges were amplified for culturally and linguistically diverse (CLD) families who often lacked the social and cultural capital needed to navigate the system (Trainor, 2010b). Culturally and linguistically diverse parents experience systemic barriers such as limited interpretation, discrimination, and cultural differences that restrict their engagement (Buren et al., 2018; Doucet, 2011; Harry, 2008; Kalyanpur et al., 2000; Sanders-Smith et …

A Lineage Of Contemporary Jazz Violin, Tsu Hao Kuo

Dissertations

The development of jazz violin has always been multifaceted. Not only has it followed the evolution of jazz, but it has also established its own parallel genres. Since the swing era, the violin no longer remains a top choice for jazz musicians as opposed to early jazz musicians who often doubled on string instruments. Intriguingly, the decline of its popularity in larger ensembles did not inhibit the growth of the jazz violin. Not only did jazz violinists thrive in small jazz ensembles, but its distinct blend with other string music genres also reached styles beyond the common narrative of jazz …
