Nowadays, AI systems have been applied widely in a variety of predictive tasks, from objective detection to text classification. These AI systems have greatly advanced automated decision-making. However, sometimes humans and AI systems think in very different ways, which means humans and AI systems might use different evidence to make predictions. In this study, we are using sentiment analysis of Amazon product reviews as a case study. Humans will judge sentiments of different words with different AI explanations. Human and AI judgments will be compared to find to which extend human and AI knowledge align.

In this study, we want to learn more about how informational professionals interact with large language models such as ChatGPT, Bing AI, and Google Bard. We are interviewing and conducting diary studies with information professionals (e.g. finance, law, IT, business, academia, journalism, and consulting) who regularly use these systems in their work to understand the information practices they engage in while using these systems. Previous study participants have noted that the diary entries enabled them to reflect more deeply on their use of these tools and the interview has helped synthesized what they have documented. We hope you may find such benefits in your participation as well.

For my dissertation, I am broadly interested in looking at the effects that the latest wave of the feminist movement in Latin America has had on women's lives. I am particularly interested in looking at the past 7 years, starting in 2015, during which the movement has grown and peaked to become the most active political force in the region (Gutierrez 2019). While most research examining the rise of this movement has focused on theorizing its agenda, consisting of novel organizing and coalition-building strategies (Gago 2020; Furtado and Sosa 2020), I am interested in understanding how this movement shapes lived experiences and concrete social outcomes in women's lives-which we currently know little about.

We're all different. But when we visit the doctor, our treatments are often the same. We think one day health care should be tailored for you. This is called precision medicine. And research can help us get there. Taking part in the All of Us Research Program involves sharing information about your health, habits, and what it's like where you live. If you are 18 or older and live in the United States, you may be able to take part!

We are doing a study to help us adapt a physical activity program for adults with intellectual disabilities. We are looking for adults with intellectual disabilities, parents/caregivers, support staff, and exercise professionals to complete a survey and take part in interviews or focus groups to provide feedback on a physical activity program. The program includes weekly group fitness meetings, one-to-one coaching meetings, and an app to support setting, monitoring, and achieving exercise goals.
