abstract: This dissertation explores the technolinguistic brokering experience of adolescents and (im)migrant non-English speaking mothers in acculturating families. By focusing on the performance of cultural intermediation, I examine the dimensions of technolinguistic brokering and their influence upon the Adolescent Language Technology Broker (ALTB) and mother relationship. Additionally, I explore the factors of power present as a result of the complexities of the ALTBs role to connect their mother to the English speaking community. This research uses a qualitative approach to explore concepts of expertise, knowledge, (inter)dependence, relational maintenance and quality, and power in the dialogic cultural relationship. Research indicates that expertise in the form of culture, cultural interactions, multilingual, and relational maintenance and quality contribute to the ALTBs capabilities in building cultural relationships. Moreover, to assist in dealing with power tensions created by differing levels of expertise and knowledge, ALTBs and mothers communicatively construct an (inter)dependent cultural relationship. I highlight practical implications, discuss limitations, and provide recommendations for future directions. / Dissertation/Thesis / Doctoral Dissertation Communication 2020
