Main contributors:
Blei, David
Summary:
Probabilistic topic models provide a suite of tools for analyzing large document collections. Topic modeling algorithms discover the latent themes that underlie the documents and identify how each document exhibits those themes. Topic modeling can be used to help explore, summarize, and form predictions about documents. Topic modeling ideas have been adapted to many domains, including images, music, networks, genomics, and neuroscience. Traditional topic modeling algorithms analyze a document collection and estimate its latent thematic structure. However, many collections contain an additional type of data: how people use the documents. For example, readers click on articles in a newspaper website, scientists place articles in their personal libraries, and lawmakers vote on a collection of bills. Behavior data is essential both for making predictions about users (such as for a recommendation system) and for understanding how a collection and its users are organized. In this talk, I will review the basics of topic modeling and describe our recent research on collaborative topic models, models that simultaneously analyze a collection of texts and its corresponding user behavior. We studied collaborative topic models on 80,000 scientists' libraries from Mendeley and 100,000 users' click data from the arXiv. Collaborative topic models enable interpretable recommendation systems, capturing scientists' preferences and pointing them to articles of interest. Further, these models can organize the articles according to the discovered patterns of readership. For example, we can identify articles that are important within a field and articles that transcend disciplinary boundaries. More broadly, topic modeling is a case study in the large field of applied probabilistic modeling. Finally, I will survey some recent advances in this field. I will show how modern probabilistic modeling gives data scientists a rich language for expressing statistical assumptions and scalable algorithms for uncovering hidden patterns in massive data.

Main contributors:
Herrera-Sobek, Maria, Winick, Stephen D.
Summary:
Some songs pertaining to the “música tropical” genre, or music exhibiting tropical rhythms from both the Pacific and Atlantic coasts, feature Afro-mestizo protagonists in their lyrics. My study explores the imaginaries constructing the subjectivities of Afro-mestizo men and women and posits that these gender constructions are different between the two sexes. Men tend to be depicted more harshly than women. Both, however, are depicted in a stereotypical and racist manner. My study incorporates feminist and critical race theories as well as postcolonial theories in the analy- sis and hermeneutics of the representation of Afro-mestizos in the lyrics of these songs.

Brady, Erika, Kruesi, Margaret, Primiano, Leonard Norman
Summary:
Many years ago as a graduate student studying William Langland’s Vision of Piers Plowman, I came upon what was evidently a popular scatological riddle pertaining to a profound theological teaching. Since that time I have continued to ruminate over the role of humor—especially sexual and scatological humor—arising from within vernacular Catholicism. In this talk, I will consider the serious play of such forms of expression and their significance for folklorists concerned with the nature of belief in the sacred.

25. "Contentless" Digital Collections (59:07)

Date:
2015-10-14
Main contributors:
Cowan, William, Floyd, Randall, Pierce, Daniel
Summary:
Generally, when we think of a digital collection or repository, we think of digital images, ebooks, audio and video files. But some important digital collections, such a bibliographies, don't have content per se but consist of metadata describing a physical object such as a book, a digital object such as an audio recording or an event such as an opera performance. Not surprisingly, this kind of "contentless" digital object is dependent on metadata to describe it. And while we have standards for bibliographic entries in books and articles, we need more complex metadata for digital bibliographic entries. For the past several months, the Library Technology Software Development group has been working on exactly how to represent these contentless digital objects in our Fedora digital repository using the Hydra based software development environment. Using The Televised Opera and Musical Comedy Database as a sample, we will discuss the work we have done to create a general bibliographic tool for the Fedora Digital Repository.

Main contributors:
Hardesty, Juliet, Halliday, Jim
Summary:
The Center for Biological Research Collections (CBRC) at Indiana University (http://www.indiana.edu/~cbrc/) is a consortium of research collections including botany, zooarchaeology, and paleontology collections. This group is digitizing biological specimens to make them available online for teaching and research. Some of these specimens will be digitized as 2-dimensional photographic images while others, particularly bone specimens, are being digitized in 3D to allow for manipulation and visualization in a standard web browser. The Libraries are teaming up with CBRC to help store these collections in a variety of file formats, along with accompanying metadata. The CBRC uses a pre-existing metadata management system called Specify (http://specifysoftware.org/) and we are working to bring the metadata in that system together with repository software we use (Hydra/Fedora) to ensure these digitized items can be archived and managed for the long-term, as well as made discoverable and accessible online. Join us to learn about this work, see some 3D content in action, and have some fun with science!

30. Digital History: From Design to Construction to Management to Maintenance (1:03:56)

Date:

Main contributors:
Dierks, Konstantin
Summary:
I have been the principal investigator for an ongoing digital history project entitled ‰ÛÏGlobalization of the United States, 1789-1861.‰Û As a trained historian I have had a steep learning curve in turning my historical vision into digital reality. This learning curve has involved many more steps and levels than I ever imagined. Indeed, now that the foundational website for this project is nearing stability, the maintenance phase is immediately presenting new technical challenges. This presentation is meant to walk through this learning curve from the perspective of a faculty scholar initiating and then overseeing a long-term digital history project. I shall start, necessarily, with the historical vision, digital ignorance, and management naivete I initially brought to the project. I shall then scrutinize each subsequent phase of the project: what had to be learned, what help was needed, what resources had to be marshaled, et cetera. We might ask ‰ÛÏhow was everything actually done each step of the way?‰Û but the important unavoidable fact is that I can only answer this question from a limited perspective. I thus can represent one portion of a digital history project: the faculty scholar with heavy research and teaching responsibilities who contributes their mite to a collaboration where all participants have heavy responsibilities of their own. For my part, I had to learn how to translate historical research into a digital format; I had to learn arcane technical vocabularies; and I had to learn how to manage a network of necessarily part-time work.

31. Maps for Our Maps: Improving Access to Historic Maps with Interactive Indexes (36:23)

Date:
2015-09-16
Main contributors:
Quill, Theresa
Summary:
The Herman B Wells Library at Indiana University has been digitizing its collection of Soviet Military Topographic maps from 1880 to the 1940s. These maps were created by the Soviet Military for internal intelligence purposes and classified as top secret. During World War II, some sheets were captured by German forces and were later captured by the U.S. Military. These maps bear stamps from Nazi Germany and are marked ‰ÛÏcaptured map.‰Û After the fall of the Soviet Union, many more maps made their way to libraries across the United States, including the library at Indiana University. Previously, in order for a user to find these topographic maps, he or she must be able to read an old and unclear index map to determine the appropriate sheet. This is especially vexing in the case of Eastern Europe, where borders and place names changed frequently in the early 20th Century. Based on a framework created by Christopher Thiry at the Colorado School of Mines, I used GIS to create an online, interactive index for this map set. The index allows for searching, panning, and zooming in a familiar online map environment. Eventually, all of the digitized maps will be linked to the interactive index and included in a collaborative index project hosted on ArcGIS Online with the goal of facilitating user interaction and of preserving the maps in this digitized environment.

32. Content Strategy as a Model of Web Stewardship (55:27)

Main contributors:
McDonald, Courtney Greene, Haines, Anne
Summary:
Content strategy is an emerging area of expertise related to user experience design work, defined as ‰ÛÏplanning for the creation, delivery, and governance of useful, usable content.‰Û This session will provide a brief overview of content strategy concepts and describe how a well-articulated content strategy can enable a better user experience through thinking holistically and strategically about web content -- in other words, in stewardship. We'll also present a brief case study of how, through implementing these tools and processes, our small department was empowered to stop simply chasing web pages around and instead invest our efforts into crafting a user-centric, sustainable web presence for the IUB Libraries (http://libraries.indiana.edu).

Summary:
Thanks to Mauri Williamson, the Pioneer Village has become one of the most popular and beloved activities of the Indiana State Fair. The Village celebrates Indiana’s agricultural heritage through displaying antique tractors and farm implements, as well as by hosting old-time craft and farm-life demonstrations. The roots of the Village date to 1961 when Mauri, then the Purdue Agricultural Alumni Association secretary, brought a collection of farming artifacts from the university to create an educational display at the Indiana State Fair. In 1968, the Village began to grow when the Fair built a barn dedicated to housing its unique collection. From fiddling and quilting to threshing and storytelling, today the Pioneer Village features dozens of musicians, artisans, and demonstrators who share their talents with fairgoers. More than just the founder of the Pioneer Village, for over 54 years Mauri Williamson has worked to make the Village a memorable experience for countless Hoosiers. The Indiana State Fair Master Award was established to recognize long-time fair participants, who share their knowledge and talents at the Fair. Indiana University's Traditional Arts Indiana and Indiana State Fair are Honored to name Mauri Williamson the 2015 Indiana State Fair Master.

36. Willow Work: Viki Graber, Basketmaker (07:50)

Date:
2015-08-18
Summary:
Folklorist Jon Kay made this short documentary for the exhibition, "Willow Work: Viki Graber, Basketmaker." The exhibit explored the work of Viki Graber a willow basketmaker from Goshen, Indiana. Viki learned willow basket weaving at the age of twelve from her father, who was recognized by the National Endowment for the Arts as a 2009 National Heritage Fellow. Where once her family plied their talents to make utilitarian workbaskets, Viki makes baskets for collectors and to sell at art shows and galleries. While using the same tools and methods as her great-grandfather, Viki's keen sense of color and innovative designs have elevated her family's craft to a new aesthetic level. Sponsored by the Indiana University College of Arts and Sciences as part of their Fall 2015 Themester @Work: The Nature of Labor on a Changing Planet, the exhibition and the video were on display at the museum from August 18 through December 20, 2015.

39. Moving Beyond Statistical Significance: Using Effect Sizes in NSSE (48:11)

Date:
2015-06-23
Main contributors:
Louis Rocconi, Robert M. Gonyea
Summary:
What constitutes a meaningful difference in your NSSE results? With large samples it is common for very small differences to be statistically significant. That's why effect sizes, which provide a measure of "practical" significance, are so important. Based on a recent analysis of statistical comparisons of Engagement Indicators and High-Impact Practices, we have derived new recommendations for interpreting small, medium, and large effect sizes. In this webinar, we will explain our recommendations and invite participants to consider their use with their NSSE results.

40. Tom Olin - ADA Legacy Bus Tour (18:24)

Date:
2015-06-19
Main contributors:
Indiana Disability History Project
Summary:
“The shot that was heard around the world for people with disabilities,” is how one of Tom Olin’s photographic images has been described. As part of the ADA at 25 Legacy Tour, the Monroe County History Center in Bloomington, Indiana hosted an exhibit of Tom Olin’s work. On June 19, 2015, Tom gave a public talk in association with the exhibition. He was also present as the driver of the touring ADA Legacy bus. It made Indiana stops in Bloomington, Monticello, and Indianapolis during a national tour celebrating the 25th anniversary of the Americans with Disabilities Act. Tom has become widely known for the powerful advocacy of his photography focusing on the disability rights movement. In this videotaped talk, he discusses how he became involved in documenting the struggle for the rights of people with disabilities, and provides information about photographs in the exhibit. Some of the iconic photographs he discusses include images of the event now referred to as the Capitol Crawl. Depicting the landmark protest where people got out of their wheelchairs to ascend the steps of the U.S. Capitol building, it became “the shot that was heard around the world.” The action on March 12, 1990 was initiated by the activist organization ADAPT (Americans Disabled for Accessible Public Transit ). Tom identifies disability leaders at the protest and points out that his eight-year-old niece, Jennifer Keelan, is among those shown crawling up the steps. Tom explains that even though the “Crawl” took place just a few months before the ADA was passed into law, there were numerous attempts being made to weaken its provisions. “In Congress, you had the Senate and the House conferring on the bill that was to be. And they had all these different ways of how they thought the bill should look like.” Tom also describes photographs in the exhibit documenting other ADAPT actions in Memphis and at the federal building in Atlanta. It’s up to us, he says, to make sure the work of grassroots activists continues. “I see things happening. You know, I'm really impressed with a lot of young people.”
