On Thursday, April 17 and Friday, April 18, Duke University will host a visit from Francesca Samsel, a visual artist who uses technology to develop work on the fulcrum between art and science. Francesca works as Research Assistant Faculty in the Computer Science department of the University of Texas at El Paso, is a Research Affiliate with the Center for Agile Technologies at the University of Texas at Austin, and is also a long-term collaborating partner with Jim Ahrens’ Visualization Research Team at Los Alamos National Labs.
Francesca will give two presentations during her visit. A presentation on Thursday afternoon for the Media Arts + Sciences Rendezvous series will address the humanities community and present recommendations for work with scientists and visualization teams. A presentation over lunchtime on Friday for the Visualization Friday Forum will describe a variety of collaborations with scientific teams and address the benefits that can come from incorporating artists into a scientific research team.
Francesca’s visit is sponsored by Information Science + Information Studies (ISIS), with additional support from Media Arts + Sciences. We hope you can join us for one or both of the presentations!
The second annual Duke Student Data Visualization Contest brought in another round of beautiful and insightful submissions from students across the university. The judging panel of five members of the Duke community evaluated the submission based on insightfulness, broad appeal, aesthetics, technical merit, and novelty. This year, the panel awarded a first place, second place, and two third place awards.
Each of these winners will be honored at a reception on Friday, April 4, from 2:00 p.m. to 4:00 p.m, in the Brandaleone Center for Data and GIS Services (Perkins 226). They will each receive a poster version of their projects and an Amazon gift card. The winners and other submissions to the contest will soon be featured on the Duke Data Visualization Flickr Gallery.

Please join us on the 4th to celebrate another year of exciting visualization work at Duke!
How do you support 57,860 online students learning R and statistics ? Late last fall, Data and GIS Services shared this challenge with Professor Mine Çetinkaya-Rundel and the staff of CIT as we sought to translate Professor Çetinkaya-Rundel’s successful Statistics 101 course to a Coursera class on Data Analysis and Statistical Inference. While Data and GIS Services has supported Statistics 101 students for several years identifying appropriate data and using the R statistical language for their assignments, the scale of the Coursera course introduced new challenges of trying to provide engaging data to a very large audience without having the opportunity to provide direct support to everyone in the class.
In our initial meetings with Professor Çetinkaya-Rundel, she requested that Data and GIS create data collections for the course that would provide easy access in R and would include a range of statistical measures that would appeal to the diverse audience in the class. The first challenge — easy access to R — required some translation work. While R excels in its flexibility, graphics, and statistical power, it lacks some of the built in data documentation features present in other statistical packages. This project prompted Data and GIS to reconsider how to provide documentation and pre-formatted R data to an audience that would likely be unfamiliar with R and data documentation.
The second challenge — finding data that covered a wide range of interesting topics — proved much easier. The General Social Survey with its diverse and engaging questions on a wide range of topics proved to be an easy choice for the class. The American National Election Studies, also offered a diverse set of measures of public opinion that suited the course well. With these challenges identified and addressed, we spent the end of 2013 selecting portions of the data for class (subsetting), abridging the data documentation for instructional use, and transforming the data to address its usage in an online setting (processing missing values for R, creating factor variables).
As Professor Çetinkaya-Rundel’s class launches on February 17th, this project has given us a new appreciation of providing data and statistical services in a MOOC while also building course materials that we are using in Statistics 101 at Duke. While students begin the Coursera course on Data Analysis and Statistical Inference, students in Professor Kari Lock Morgan’s Statistics 101 class will use these data in their on-campus Duke course as well. We hope that both collections will reduce some of the technological hurdles that often confront courses using R as well as improving statistical literacy at Duke and beyond.

Say you’ve been making hella maps or data stories all day. Now you need to move to your comfy work spot and you need your data to come with you. If you use Duke’s CIFS, moving around is easy, and all of your files are already backed-up.
In this example we follow the researcher, Ms. Stu Fac-Staff. Stu is part student, part faculty, and part staff at Duke University. She needs a portable place for her data and wants easy access from her home, lab, and devices. Stu also needs to easily share data with colleagues. No problem! Stu uses CIFS.
Here’s the scenario. Ms. Stu Fac-Staff walks into the Data & GIS Lab in the Duke University Libraries with a flash drive full of data tables. She gathers more supporting data and some advice about crunching the numbers. Stu finishes her day with a visualization and map. (Proudly, Stu imagines this is going to get the A. ”Is this grant worthy?” Stu asks herself. ”You bet your NSF Application it is!”) Meanwhile, her flash dive is now full and all she wants is to SAVE THE DATA, CONVENIENTLY for later retrieval back home. So Stu stores the data on the Duke Cloud (CIFS.)
How do I get the free CIFS Space and how much can I use/access?
- Duke University provides 5 GB (at least!) of easily accessible Cloud-storage space to all faculty, students, and staff
- If you need more space, larger quantities are available upon request
- The space is called CIFS and is an OIT supported personal home directory of portable file space; CIFS is a mappable drive on your device and the files are backed up
- Students are provisioned CIFS space automatically. Faculty & Staff must request the space through the OIT Service Desk
How do I access the data from my device?
- In the Data & GIS Lab, after using your NetID to login, open the Windows File Explorer and your CIFS space will be mapped as drive Z.
- After you leave our Data & GIS Lab, all you have to do is “map the drive” on your own machine
- Web – For easy distribution to colleagues, you might want to access or distribute your files through the web. To do this, store the files in your ‘public_html‘ directory inside of your CIFS space. Now the files can be downloaded via a web browser. This method is, by default, open to the world; you may want to take additional steps to secure this public_html directory (see below.)
Can I Secure the Data?
- Are you trying to access your mapped drive from off campus?
- Use the VPN directions
- The CIFS protocol encrypts NetID/password but it does not encrypt your data stream over the Internet. If you’re connecting from an unencrypted or untrusted network (e.g. wireless in the coffee shop), the VPN allows for a secure connection.
- Did you put files in your public_html folder?
- Unlike the default CIFS space, placing files in the ‘public_html’ directory means they become accessible to the world
- You can control and limit access by following OIT’s “htaccess” instructions
Data & GIS Services will soon be accepting submissions to its 2nd annual student data visualization contest. If you have a course project that involves visualization, start thinking about your submission now!
The purpose of the contest is to highlight outstanding student data visualization work at Duke University. Data & GIS Services wants to give you a chance to showcase the hard work that goes into your visualization projects.
Data visualization here is broadly defined, encompassing everything from charts and graphs to 3D models to maps to data art. Data visualizations may be part of a larger research project or may be developed specifically to communicate a trend or phenomenon. Some are static images, while others may be animated simulations or interactive web experiences. Browse through last year’s submissions to get an idea of the range of work that counts as visualization.
The Student Data Visualization Contest is sponsored by Data & GIS Services, Perkins Library, Scalable Computing Support Center, Office of Information Technology, and the Office of the Vice Provost for Research.
For more details, see the 2014 Student Data Visualization Contest page. Please address all additional questions to Angela Zoss (firstname.lastname@example.org), Data Visualization Coordinator, 226 Perkins Library.
On Friday, October 4, Dr. Christopher G. Healey will visit Duke University to speak at the Visualization Friday Forum.
Christopher G. Healey is an Associate Professor in the Department of Computer Science at North Carolina State University. He received a B.Math from the University of Waterloo in Waterloo, Canada, and an M.Sc. and Ph.D. from the University of British Columbia in Vancouver, Canada. He is an Associate Editor for ACM Transactions on Applied Perception. His research interests include visualization, graphics, visual perception, and areas of applied mathematics, databases, artificial intelligence, and aesthetics related to visual analysis and data management.
We hope you can join us at the Friday Forum!

Global Financial Data
Global Financial Data is a collection of financial and economic data provided in ASCII or Excel format. Data includes: long-term historical indices on stock markets; Total Return data on stocks, bonds, and bills; interest rates; exchange rates; inflation rates; bond indices; commodity indices and prices; consumer price indices; gross domestic product; individual stocks; sector indices; treasury bill yields; wholesale price indices; and unemployment rates covering over 200 countries.
The LandScan Global Population Database provides global population distribution in a gridded GIS format at 30 arc-second resolution (approximately 1×1 km cells). Oak Ridge National Laboratory developed modeling techniques to disaggregate and interpolate census data within administrative boundaries to create a GIS layer showing population distribution as accurately and as timely as possible. EastView provides this data to use in GIS software as a WMS (Web Mapping Service) or as a WCS (Web Coverage Service) to allow a user to incorporate population distribution into GIS mapping and analysis.
Data and GIS Services is happy to announce the launch of new service designed to provide detailed data management planning help online. As an increasing number of granting agencies require a data management plan as part of the grant application process, the DMPTool provides “an open source, web application that assists researchers in producing data management plans and delivering them to funders.” For Duke researchers, the tool provides constantly updated advice about how to complete a data management plan while simultaneously highlighting Duke resources available from a variety of data support providers for the planning, maintenance, and sharing of research data.
We hope that the DMPTool will streamline the grant writing process and help researchers make the appropriate connections to resources available both at Duke and beyond for data management planning. We welcome your comments and suggestions on this resource.
AboutData and GIS Services provides support for researchers at Duke in the areas of data visualization, data analysis, and data management.
