Denae Ford: Paradise Unplugged

On April 30, Denae Ford, PhD candidate in CS at NCSU, gave a talk titled Paradise Unplugged.

Denae Ford: Paradise Unplugged

Abstract:
Online question-and-answer (Q&A) communities, like Stack Overflow, have norms that are not obvious to all users. For example, novice users create and post programming questions without feedback, and the community enforces site norms through public downvoting and commenting. This can leave users discouraged from participating due to community barriers such as posting is hard, friends are easy; fear of negative feedback; and onboarding hoops.To determine how to increase participation, we investigate two mechanisms relating to 1) identity-based signals and 2) mentorship. First, we investigate peer parity and find that women re-engage significantly sooner after receiving answers from other women on their first question. Then, we conduct a month-long study in which we redirect Stack Overflow novices in the process of asking a question to an on-site Help Room. In the Help Room, novices received feedback on their question drafts from experienced Stack Overflow mentors. We present examples and discussion of various question improvements including question context, code formatting, and wording that adheres to on-site cultural norms. We find that mentored questions are substantially improved over non-mentored questions, with average scores increasing by 50%. These results suggest we can challenge socio-technical communities to recreate onboarding experiences across domains to increase participation.
 
Bio:
Denae Ford is a Doctoral Candidate in the Department of Computer Science at North Carolina State University where she is a member of the alt-code lab, advised by Dr. Chris Parnin. Her research identifies cognitive and social barriers to participation in online socio-technical ecosystems. A few of these ecosystems include remote technical interviews, Stack Overflow, and GitHub using biometric sensing through eye movements and nonverbal cues. Her most recent work dismantles barriers to participation taking advantage of identity deployment, peer parity, and community mentorship.
During her tenure at North Carolina State University, she has collaborated with researchers from MIT Lincoln Laboratory, Microsoft Research, Stack Exchange, Carnegie Mellon, University of Rochester and others. These collaborations have resulted in ACM and IEEE publications which have been presented at international conferences in software engineering and human-computer interaction.
 
Denae is a recipient of the National GEM Consortium Fellowship, National Science Foundation Graduate Research Fellowship, and Microsoft Research Ph.D. Fellowship. She holds a Bachelor of Science and Master of Science degree in Computer Science from North Carolina State University where she also minors in Cognitive Science.

Christine Bassem Receives NSF Grant on Mobility Coordination of the Crowds in Mobile Crowd Sensing Platforms

Christine Bassem, Lecturer in Computer Science, has been awarded a National Science Foundation grant to study “Mobility Coordination of the Crowds in Mobile Crowd Sensing Platforms.” The grant of $154,434 will support Christine’s work with student researchers on the intersection of algorithms, systems, mobile computing, and social computing.

Coordinated mobility depends on two areas: the mechanisms via which tasks/routes are assigned to agents; and the mechanisms via which agents are compensated for conformance, creating a rich set of problems in the fields of optimization problems, graph and data mining, and crowd economics. This project contributes towards the advancement of mobile crowd sensing for solving larger problems, with a great impact on smart cities initiatives, and the advancement of Internet of Things solutions.

Valerie Zhao ’18 recognized in CRA Undergrad Researcher Awards

Valerie Zhao ’18 was recognized with an Honorable Mention in the 2018 Computing Research Association Outstanding Undergraduate Researcher Awards.  Valerie’s summer research was previously featured here.  Valerie is currently pursuing research on the design of dynamic binary instrumentation tools for analyzing software at the machine code level, advised by Ben Wood.

Wellesley at SPLASH 2017, Valerie Zhao ’18 places 3rd in Student Research Competition

Valerie Zhao ’18 and Ben Wood participated in SPLASH 2017, the ACM SIGPLAN Conference on Systems, Programming Languages, Applications: Software for Humanity, in Vancouver, BC, in late October. SPLASH is an umbrella for several conferences and workshops in the area of programming languages.

Valerie won 3rd prize in the undergraduate category of the Student Research Competition, where she presented a poster and talk on her summer research work, Abstracting Resource Effects, undertaken at Carnegie Mellon University with Darya Melicher, Jonathan Aldrich, and Alex Potanin. Valerie’s collaborator Darya Melicher, a PhD student at CMU, presented more of their work at the OCAP workshop. Their work introduces a novel effect system that supports rigorous checking of how programs use system resources in a security-focused programming language.

Ben gave a talk on his OOPSLA paper, Instrumentation Bias for Dynamic Data Race Detection, with collaborators from Google, The Ohio State University, and the University of Washington. Their work introduced a software system for accurately detecting data races, a problematic type of concurrent programming error. The analysis helps eliminate a source of performance overhead in error detection by exploiting properties of common program patterns.

Earlier in October, Ben’s collaborator gave a talk on their paper, PARSNIP: Performant Architecture for Race Safety with No Impact on Precision, at the 50th ACM/IEEE Symposium on Microarchitecture (MICRO), in Cambridge.  This work, with collaborators at U. Penn, designed efficient hardware support for data race detection that, combined with software techniques, could eventually provide always-on concurrency error detection much like modern memory-safe languages provide explicit runtime exceptions for null dereferences or array bounds errors.

Three new faculty join Wellesley CS

Wellesley CS is delighted to welcome three new faculty members to the department for Fall 2017.

Assistant Professor Ada Lerner studies computer security and privacy, especially in interaction with social systems, the law, and human needs.  They combine low-level measurement studies and systems building projects with high-level human subjects work in order to design and build tools that solve human problems, with an eye especially for needs of underprivileged groups. Ada’s recent work explored the security and privacy needs of journalists building and evaluating Confidante, a usable encrypted email system.  Ada joins us from the University of Washington in Seattle, where they recently received their PhD.  Ada is teaching CS 230 this fall. Come introduce yourself to Ada in SCI E120!

Assistant Professor Catherine Grevet Delcourt ’09 prototypes social systems to study how people relate to each other through social technologies.  She uses the lenses of human-computer interaction and social computing to develop novel prototyping methods for social systems research and to explore the role of social media in political polarization, identity and anonymity in online conversations, personal information management, and personal informatics.  Catherine, a Wellesley alum, returns to join us via PhD work at Georgia Tech and research on social systems at Yik Yak.  She is teaching CS 115 this fall. Stop by to meet Catherine in SCI E104!

Hess Fellow Cibele Freire is a theoretical computer scientist whose research focuses on computational complexity and the theoretical foundations of databases. Her recent work has characterized several classes of database queries with respect to the notion of “resilience” — quantifying the minimal database changes required to cause a query to return different results. Cibele’s work has applications in efficiently updating database views and in explaining query results.  Cibele joins us from the University of Massachusetts at Amherst, where she conducted her PhD work.  She is teaching CS 235 this fall.  Come meet Cibele in SCI S160!

Please join us in extending a warm welcome to Ada, Catherine, and Cibele!
