Attractiveness and activity in Internet communities
Datasets of online communication often take the form of contact sequences --
ordered lists contacts (where a contact is defined as a triple of a sender, a
recipient and a time). We propose measures of attractiveness and activity for
such data sets and analyze these quantities for anonymized contact sequences
from an Internet dating community. For this data set the attractiveness and
activity measures show broad power-law like distributions. Our attractiveness
and activity measures are more strongly correlated in the real-world data than
in our reference model. Effects that indirectly can make active users more
attractive are discussed
GROUP 2018 Special Issue Guest Editorial: Another 25 Years of GROUP
For over 25 years, the ACM International Conference on Supporting GroupWork (GROUP) has been and will continue to be the premier venue for research on Computer-Supported Cooperative Work,HumanâComputer Interaction, Computer-Supported Collaborative Learning, and Socio-Technical Studies. The three papers in this special issue demonstrate GROUPâs continued commitment to diverse research approaches, emerging technologies, and collaborative work. We hope you enjoy these papers and, like us, look forward to another 25 years of GROUP.https://deepblue.lib.umich.edu/bitstream/2027.42/146739/1/Robert et al. 2018.pdfDescription of Robert et al. 2018.pdf : Articl
First Women, Second Sex: Gender Bias in Wikipedia
Contributing to history has never been as easy as it is today. Anyone with
access to the Web is able to play a part on Wikipedia, an open and free
encyclopedia. Wikipedia, available in many languages, is one of the most
visited websites in the world and arguably one of the primary sources of
knowledge on the Web. However, not everyone is contributing to Wikipedia from a
diversity point of view; several groups are severely underrepresented. One of
those groups is women, who make up approximately 16% of the current contributor
community, meaning that most of the content is written by men. In addition,
although there are specific guidelines of verifiability, notability, and
neutral point of view that must be adhered by Wikipedia content, these
guidelines are supervised and enforced by men.
In this paper, we propose that gender bias is not about participation and
representation only, but also about characterization of women. We approach the
analysis of gender bias by defining a methodology for comparing the
characterizations of men and women in biographies in three aspects: meta-data,
language, and network structure. Our results show that, indeed, there are
differences in characterization and structure. Some of these differences are
reflected from the off-line world documented by Wikipedia, but other
differences can be attributed to gender bias in Wikipedia content. We
contextualize these differences in feminist theory and discuss their
implications for Wikipedia policy.Comment: 10 pages, ACM style. Author's version of a paper to be presented at

Infrastructural Speculations: Tactics for Designing and Interrogating Lifeworlds
This paper introduces âinfrastructural speculations,â an orientation toward speculative design that considers the complex and long-lived relationships of technologies with broader systems, beyond moments of immediate invention and design. As modes of speculation are increasingly used to interrogate questions of broad societal concern, it is pertinent to develop an orientation that foregrounds the âlifeworldâ of artifactsâthe social, perceptual, and political environment in which they exist. While speculative designs often imply a lifeworld, infrastructural speculations place lifeworlds at the center of design concern, calling attention to the cultural, regulatory, environmental, and repair conditions that enable and surround particular future visions. By articulating connections and affinities between speculative design and infrastructure studies research, we contribute a set of design tactics for producing infrastructural speculations. These tactics help design researchers interrogate the complex and ongoing entanglements among technologies, institutions, practices, and systems of power when gauging the stakes of alternate lifeworlds
A Student-centered Regional Planning Group Activity for Non-science Majors
NOTE: This is a large file, 81.4 mb in size! This article describes the use of an authentic regional planning public workshop activity which was modified and used to introduce the Earth surface portion of an Earth Science lecture course for undergraduate non-science majors. Students applied map-reading skills and learned about the local environment while forming opinions about how the region should grow, exploring the potential consequences of their preferences (for both developers and the environment), and making judgments about the relative importance of various environmental challenges and hazards. A participant survey showed that most supported the continued development and re-use of the activity, as well as the development of one to three additional three-lecture-period activities.
