Through the Gates celebrates Valentine's Day with one of IU's beloved professors emeriti, Susan Gubar. Author of the new book Late-Life Love, Gubar talks with Dean Shanahan about the way love changes and remains the same as we age. They also discuss Gubar's life and New York Times blog Living With Cancer.
Since 2014, partners from Indiana University Bloomington (IUB) and Indiana University Purdue University Indianapolis (IUPUI) Libraries have been collaboratively developing new Samvera (formerly Hydra) software to manage and deliver page turning digital objects. In 2018, conversations with Enterprise Scholarly Systems (ESS), a partnership between IUB Libraries, IUPUI Libraries, and University Information Technology Services (UITS), expanded our project's scope. This presentation will highlight our development efforts, now known as the ESS Images project or ESSI.
In the past year, the ESSI team has developed numerous improvements to the Hyrax digital repository software, one of the Samvera community's most commonly-used open source platforms. These improvements include the ability to order, structure, and label pages within an item, replicating features available in the Pages Online service launched in 2017. Additionally, the project has implemented optical character recognition search in a community-accepted way, building upon components of the IMLS-funded Samvera Newspaper Works application.
This presentation will also discuss in-development improvements for our existing image collections. The Hyrax repository by default assumes every item can be described by the same group of metadata fields and labels, but in actuality, collections of digital images often have wildly different metadata profiles from each other. Our recent work has aimed to incorporate a model for flexible metadata developed by the Samvera Machine-readable Metadata Modeling Specification (M3) Working Group within Hyrax. This work will help IU, IUPUI, and the Samvera community better adapt Hyrax to manage and deliver a wide variety of digital library collections in a standardized way.
This presentation is a step toward understanding the problem of bias in metadata and how that impacts inclusivity in the research process. Original description provided for digital collection discovery and access as well as controlled vocabularies commonly used for subject headings (such as Library of Congress Subject Headings) have inherent biases which present challenges for researchers discovering and engaging with these collections, particularly researchers from underrepresented or historically marginalized populations. We’ll review work in this area to date and discuss possible approaches for where to go next to improve description and the academic research experience.
Using inclusive vocabularies, defined here as those vocabularies representative of and created by historically marginalized communities, is helpful for providing options when creating original description. Is it possible to also supply these vocabularies for use as a navigation aid into a system that only makes use of commonly used controlled vocabularies that are not as inclusive or representative, such as Library of Congress Subject Headings (LCSH)? This talk will explore progress in learning about the scope of available controlled vocabularies and classification schemes from marginalized communities and a proof-of-concept project to engage such a vocabulary as an information retrieval aid for search and discovery against a system using only LCSH for subjects (a typical library catalog).
This interactive workshop will consider how Open Educational Resources (OER) can alleviate the high cost Indiana University Bloomington undergraduate students pay for course materials (an estimated $1,034 each academic year). Data suggests that students will forgo purchasing expensive course materials, even when they know it will impact their success in the classroom. This session will introduce OER and discuss its benefits, critically think about challenges to OER adoption, and formulate strategies to support IU instructors in finding high-quality OER, adapting them to fit students’ needs, and creating (even in collaboration with students) customized course materials. Please bring a laptop or similar device.
As climate changes, so do pieces of culture. Pieces like car ownership, outdoor sports, and the drinks we share. This is the final episode in our beverage series, and it's all about coffee. We follow guests to Colombia, El Salvador, and Costa Rica to learn about the systems preventing coffee farmers from building climate resilience and possibilities for improvement.

Observational data often have issues which present challenges for the data analyst. The treatment status or exposure of interest is often not assigned randomly. Data are sometimes missing not at random (MNAR) which can lead to sample selection bias. And many statistical models for these data must account for unobserved confounding. This talk will demonstrate how to use standard maximum likelihood estimation to fit extended regression models (ERMs) that deal with all of these common issues alone or simultaneously.
Bayesian analysis has become a popular tool for many statistical applications. Yet many data analysts have little training in the theory of Bayesian analysis and software used to fit Bayesian models. This talk will provide an intuitive introduction to the concepts of Bayesian analysis and demonstrate how to fit Bayesian models using Stata. No prior knowledge of Bayesian analysis is necessary and specific topics will include the relationship between likelihood functions, prior, and posterior distributions, Markov Chain Monte Carlo (MCMC) using the Metropolis-Hastings algorithm, and how to use Stata’s Bayes prefix to fit Bayesian models.
Chuck Hughes, executive director of the Gary Chamber of Commerce, describes how the Chase Street spring water was like a treat for him and other children.

Gary Chamber of Commerce Executive Director Chuck Hughes shares a short history of his familial origins and what it was like for them to move from the South to the North. He compares the environment of Small Farms to that of rural Mississippi and Alabama, and describes the topography of the area, noting that it was wooded and had dirt roads. He also shares that he and other children had a "very creative childhood" because they used their imagination and surroundings in their play.

Gary Chamber of Commerce Executive Director Chuck Hughes describes his childhood in Small Farms. He says that he and his siblings thought they were "living large" in a big house filled with extended family members. Hughes' family were avid fishermen and would sometimes host fish fries for the neighborhood. He says as children they had everything they needed in Small Farms, and that "we essentially didn't leave that area...until it was time to start school."

Gary Chamber of Commerce Executive Director Chuck Hughes discusses life growing up in Small Farms. He shares stories of how he and other children were teased at school for where they came from. He attributes this treatment to the dirt and dust that settled on their clothing during their walk on dirt roads to get to school. Classmates called them "farmers from the Black Bottoms" (after a nickname used for Small Farms). But he says they were proud of their origins and the place they called home. As Hughes puts it, "We wore it as a badge of honor."

Kay Westhues interviews Kristin Huysken at Professor Hysken’s lab in Marram Hall, Indiana University in Gary, Indiana, on October 4, 2019. Professor Huysken is an Associate Professor of Geology and Chairperson in the Department of Geosciences at Indiana University Northwest. She describes the Introduction to Earth Science class field trips she led at two local artesian wells: the Gary spring on Chase Street, and the spring at Beverly Shores, Indiana. She describes the geological processes that produce an artesian well, and some specific geologic features in the region surrounding the spring. Part of the Spring at Small Farms Oral History Project.

Professor Kristin Huysken, an Associate Professor of Geology and Chairperson in the Department of Geosciences at Indiana University Northwest, discusses the science of artesian wells. She says that the purity of the water in these springs is dependent upon the amount of time the water spends in the aquifer. "The aquifer itself acts as a filter," she says. "The longer time the water can spend in that aquifer," she explains, "If the pore spaces are small enough and you know it takes enough time to get through, that's good. It means you're drinking old water."

Professor Kristin Huysken explains the proper conditions necessary for an artesian well to flow. "It has to be like...a sandwich," she says. "You have to have an impermeable layer...with a permeable layer between it," that filters the water. "The second criterion," she explains, "is that the recharge area...where the rain is coming in and charging, the system, has to be higher than the discharge area." Huysken then uses a diagram to provide a visual representation of how artesian wells work.
