Romaguera APPROVED: Dissertation Committee: Major Professor Valerie Karno Carolyn Betensky Ian Reyes Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2017 Abstract This dissertation explores the author-text-reader relationship throughout the publication of works of serial fiction in different media. Following Pierre Bourdieu’s notion of authorial autonomy within the fields of cultural production, I trace the outside influence that nonauthorial agents infuse into the narrative production of the serialized. To further delve into the economic factors and media standards that encompass serial publishing, I incorporate David Hesmondhalgh’s study of market forces, originally used to supplement Bourdieu’s analysis of fields.

At Amazon, the infrastructure powers over 25,000 skills deployed through the ASK, as well as AWS’s Amazon Lex SLU Service. The ASK emphasizes flexibility, predictability and a rapid iteration cy- cle for third party developers. It imposes inductive biases that allow it to learn robust SLU models from extremely small and sparse datasets and, in doing so, re- moves significant barriers to entry for software developers and dialogue systems arXiv:1711.00549v4 [cs.CL] 2 Mar 2018 researchers. 1 Introduction Amazon’s Alexa is a popular digital assistant that was not designed around a smart phone, but rather as a service for ambient computing [1] in the home. Due to the intuitiveness of the Voice User Interface (VUI), the demand from software engineering teams for voice controlled features far out- stripped the pace at which the language experts designing Alexa’s SLU system could accommodate them.

With Amazon Connect, Financial Services organizations can improve their customer engagement while reducing costs and simplifying their contact center technology stack. 2 Why did we build Amazon Connect?
