Exhibits, Films and Lectures Calendar
Opening Reception: April 28 at 7:00 p.m
James Walters, Department of Earth Science, will discuss his research on "Reconstructing Northeast Iowa's Periglacial Environment."
During late Pleistocene time, the landform region known as the Iowan Surface of Northeast Iowa, situated between the Des Moines Lobe glacial ice to the west and the Lake Michigan glacial lobe to the east, experienced a periglacial environment. The characteristics of this former environment are not well known, but the presence of features known as “ice-wedge casts” indicates that permanently frozen ground (permafrost) was present. The actual timing of this event is also not well known, but recent optically stimulated luminescence dating of sands from sand stringers overlying the pre-Illinoian till suggests that these events were taking place between about 24,000 and 16,500 years ago.
For the last several years, Walters has investigated the relict periglacial features of the Iowan Surface in an attempt to reconstruct the severity, timing and other characteristics of this environment.
Lynda Yates, Macquarie University, will address issues faced by adult second language learners as they seek to master not only the language but also the professional and community cultures’ underlying expectations about how they should talk at work. Recent research into the demands of three professions--childcare, teaching and medicine--will be considered.
Sponsored by the TESOL Club, the Anthropology Club (NISG) and the Department of Languages & Literatures.
A garden provided poor families and their neighbors with food and camaraderie after rioting in the early 1990's. The Garden explores the resiliency of Los Angeles farmers in creating a community plot. They confront the cordons of wealth and commerce: a bittersweet story of self-sufficiency and fortitude.
Designing Healthy Communities is a four-part series that takes a comprehensive look at the impact America’s built environment has on public health, and at the people and communities working to turn things around through innovative solutions.
In the final episode, "Searching for Shangri-La," Dr. Jackson searches past and present America for model communities large and small that embody the intricate balance of health promoting design and human needs. Does the perfect community exist?
View the evening sky from the UNI observatory located on the roof of McCollum Science Hall. Meet near the polar bear outside of room 137 before 9 p.m. to be escorted to the roof. The event goes forward regardless of the weather.
Sarah Diesburg, computer science, will present "Ghosts of Past Data: Challenges and Advances in Secure Deletion of Files."
"Secure deletion is the act of completely removing file data from electronic storage so that it cannot be recovered. This lecture will briefly outline why this is so challenging today and introduces TrueErase, my backwards-compatible secure-deletion framework. Bring your lunch; cookies will be provided.
