“Hey Google, Do Unicorns Exist?”: Children Finding Answers Through Conversational Agents

Description:: Children are known to be curious and persistent question-askers. The pervasiveness of voice interfaces represents an opportunity for children who are still learning to read and write to independently search the Internet by directing questions at conversational agents such as Amazon’s Alexa, Apple’s Siri, and the Google Assistant. However, little...

There's Hope in the System: Towards a Strength-Driven Design Approach to Support the Information Work of Sheltered Emerging Adults

Description:: This dissertation asks how can researchers more equitably design sociotechnical interventions to support the information work of sheltered emerging adults. Through two research studies, I explore the technology use in fulfilling the information needs among this population as well as how their environment impacts their strengths and information practices. I...

Model Positionality: A Novel Framework for Data Science with Subjective Target Concepts

Description:: Data Science and related fields like Artificial Intelligence, Machine Learning, and Statistics provide indispensable research methods for understanding a wide variety of phenomena from large datasets. However, as methodical and empirical as these methods aim to be, there are many subjective and discretionary choices that the data scientist must make...

Biases as Values: Evaluating Algorithms in Context

Description:: This dissertation asks how researchers can create more equitable algorithmic systems. Ultimately, this thesis explores methods and implications of representing subjects of analysis in the design and evaluation of algorithmic systems. I also unpack how algorithmic tools measure and quantify human behavior, giving heed to the potential impacts of these...

Presenting the Self on Unstable Ground: Adaptive Folk Theorization as a Path to Algorithmic Literacy on Changing Platforms

Description:: Algorithmically-driven social platforms present a challenge for self-presentation and identity management by obscuring audiences behind algorithmic mechanisms. Users are increasingly aware of this and actively adapting through folk theorization, but we do not know how users are coping with the constant change endemic to these platforms. We also do not...

Caring Together: A Digital Ethnography of How People with Mental Illness Participate Online

Description:: Social media and online forums provide spaces where people can gather beyond restrictions of geographic proximity. For some individuals with mental illness, these spaces are vital; providing outlets and communities where a multitude of experiences are accepted and understood, rather than judged against normative, often ableist standards. For nearly three...

The Effect of Availability, Message Attributes, and Relational Variables on Predicting Mobile Responsiveness

Description:: Responsiveness -- the time it takes for a message recipient to respond to a message -- has long been of interest to scholars in the fields of computer-mediated communication and human-computer interaction. It has been hypothesized that responsiveness is used to signal emotional information, and many empirical studies have demonstrated...
