Ramble solves problems that accompany traditional journaling by making the journaling process more accessible and requiring less time from the user.

The Queer Dictionary, Mia Lew

Graphic Communication

With the government continually obstructing queer education in public schools, it becomes harder and harder for queer people to understand themselves than in turn, have the tools to explain what they are going through to others. This is a problem but in turn an opportunity. While there are queer literature and children’s books out there, they typically only encompass one story or one view on queerness. Thus, this project's main goal is to encompass queerness as a whole by using as many LGBTQ+ words as possible, people's stories under each word, historical graphics, highlights on the internationality of queerness, pronoun …

Find Your Flow: A Menstrual Health Social Media Campaign, Sarah Hamp-Adams

Kinesiology and Public Health

In many cultures, menstruation is surrounded by silence and shame instead of being celebrated as a sign of health and vitality. Globally, challenges, including stigma surrounding menstruation, create barriers for menstruators (White, 2013; Crawford, 2014; Garg, 2015). It proves to be difficult for young menstruators to navigate menarche due to the taboos and socio-cultural restrictions surrounding menstruation (Sharma,2015). Encouraging women to have open conversations about their periods is necessary to combat these challenges.

To understand how to address the stigmas around menstruation, the researchers first conducted a literature review, revealing that education messages via the Internet, posters, storytelling, and peer …
