81. The Pleasures and Challenges of Collaborative Qualitative Research (1:11:38)

Armstrong, Elizabeth
Summary:
Contemporary qualitative research often involves teams of researchers collaborating on a project. Armstrong will discuss the pleasures and challenges of this style of research, drawing both on her experiences working with Indiana University sociology alum Laura Hamilton and a team of graduate and undergraduate researchers on Paying for the Party and her more recent experiences at the University of Michigan. Larger teams can collect more data and leverage the diverse social identities of researchers to gain entree to research sites and participants. Collaboration can also add rigor to data analysis, as classifications and interpretations are debated by the research team. However, collaboration introduces challenges of coordination at all stages of the process. These challenges grow with the size of the research team. In addition, the temptation to collect large volumes of data creates risks that the principal investigator may fall into the role of administrator rather than fieldworker and may lose touch with the data. Goffman argued for full immersion in the field and saw the ethnographer's embodied reactions as invaluable. This embodied knowledge can not easily inform the final product if the person who participated in the ethnographic or interview interactions is not the one doing the writing.

90. HathiTrust Research Center: Opportunities for Large-Scale Text Analysis in the Social Sciences (21:38)

Date:

Main contributors:
Kouper, Inna
Summary:
Textual analytics creates opportunities to ask new questions or test existing theories through a new lens. The HathiTrust (HT) collection can be considered one of the largest academic libraries in the US. How can a researcher unlock many insights of this digital library? What kinds of social science questions it can help to address? The HathiTrust Research Center (HTRC) has been developing computational tools to leverage the HathiTrust collection and its metadata. In this presentation we will provide an overview of the HathiTrust digital library and the suite of tools from the HTRC and invite participants to think creatively about how a corpus of ~14 billion volumes of text can be useful to them.

94. Introducing graphical access to IU's supercomputers with Karst Desktop Beta (1:01:57)

Date:
2016-01-29
Main contributors:
Thota, Abhinav
Summary:
Supercomputers are designed to use a command line interface and batch processing system. This means users accustomed to modern graphical interfaces must overcome a steep learning curve when switching to supercomputers. Learn how UITS Research Technologies is tackling this problem using a new graphical interface for the Karst supercomputer. Participants will have the opportunity to test the service after the presentation on their laptop/desktop devices. Abhinav Thota is a Principal Engineer in the Research Technologies division of UITS/PTI. He is part of the Scientific Applications and Performance Tuning (SciAPT) team and helps users efficiently use HPC resources at IU.

95. The Psychology of Risk (1:19:39)

Date:
2016-12-14
Main contributors:
Slovic, Paul
Summary:
Studies of risk perception examine the judgments people make when they are asked to characterize and evaluate hazardous activities and technologies. This research aims to aid risk analysis and policymaking by (i) providing a basis for understanding and anticipating public responses to hazards and (ii) improving the communication of risk information among lay people, technical experts, and decision makers. This work assumes that those who promote and regulate health and safety need to understand how people think about and respond to risk. Without such understanding, well-intended policies may be ineffective. Among the questions the lecturer will address are: How do people think about risk? What factors determine the perception of risk and the acceptance of risk? What role do emotion and reason play in risk perception? What are some of the social and economic implications of risk perceptions? Along the way, he will address such topics as the subjective and value-laden nature of risk assessment; the multidimensionality of risk; sex, politics, and emotion in risk judgments; risk and trust; and risk perception and terrorism.

96. Studying people through digital devices and social media (30:20)

Date:

Main contributors:
Crandall, David
Summary:
Over 2 billion people now own smartphones, which are actually sophisticated mobile computing devices that can run applications, take photos, access the internet, and collect GPS, motion, and other sensor data. Many people use these devices to access online social media sites, which have also exploded in popularity over the last few years. For example, *each day* over 1 billion people log in to Facebook, and collectively upload about 350 million photos and share nearly 5 billion status updates and other pieces of content. As people use their digital devices and services, they are (without necessarily realizing it) leaving behind "digital footprints" about themselves and their behavior, including the things they "like", the people they communicate with, the places they visit, the photos they take, and so on. This is creating huge datasets about the world and human behavior, that could potentially be used to aid studies in a range of scientific disciplines. In this talk, I'll give a high-level overview of some of our recent work that has used mobile devices and online social media to collaborate with studies in sociology, psychology, and ecology. I'll talk about some of the advantages and disadvantages of this type of analysis, including the many sources of potential bias, and very real concerns about privacy.
