Editors' Message

It is our great pleasure to welcome you to this issue of the Proceedings of the ACM on Human Computer Interaction, the second to focus on the contributions from the research community Computer-Supported Cooperative Work and Social Computing (CSCW). This journal model allows for rapid publication of papers shortly after acceptance as well as... (more)

Quotidian Report: Grassroots Data Practices to Address Public Safety

We examine the local data practices of citizens in Mexico who use Facebook sites as a platform to report crimes and share safety-related information. We conducted 14 interviews with a variety of participants who collaborate as administrators and contributors of these online communities. The communities we examined have two central components: the... (more)

Hackers, Computers, and Cooperation: A Critical History of Logo and Constructionist Learning

This paper examines the history of the learning theory "constructionism" and its most well-known implementation, Logo, to examine beliefs involving both "C's" in CSCW: computers and cooperation. Tracing the tumultuous history of one of the first examples of computer-supported cooperative learning (CSCL) allows us to question some present-day... (more)

Testing Waters, Sending Clues: Indirect Disclosures of Socially Stigmatized Experiences on Social Media

Indirect disclosure strategies include hinting about an experience or a facet of one's identity or relaying information explicitly but through another person. These strategies lend themselves to sharing stigmatized or sensitive experiences such as a pregnancy loss, mental illness, or abuse. Drawing on interviews with women in the U.S. who use... (more)

Acting the Part: Examining Information Operations Within #BlackLivesMatter Discourse

This research examines how Russian disinformation actors participated in a highly charged online conversation about the #BlackLivesMatter movement and police-related shootings in the USA during 2016. We first present high-level dynamics of this conversation on Twitter using a network graph based on retweet flows that reveals two structurally... (more)

With Few Eyes, All Hoaxes are Deep

Quality control is critical to open production communities like Wikipedia. Wikipedia editors enact border quality control with edits (counter-vandalism) and new article creations (new page patrolling) shortly after they are saved. In this paper, we describe a long-standing set of inefficiencies that have plagued new page patrolling by drawing a... (more)

Framing Effects: Choice of Slogans Used to Advertise Online Experiments Can Boost Recruitment and Lead to Sample Biases

Online experimentation with volunteers relies on participants' non-financial motivations to complete a study, such as to altruistically support science or to compare oneself to others. Researchers rely on these motivations to attract study participants and often use incentives, like performance comparisons, to encourage participation. Often, these... (more)

Departing and Returning: Sense of Agency as an Organizing Concept for Understanding Social Media Non/use Transitions

Recent work has identified a variety of motivations for various forms of technology use and non-use. However, less work has closely examined relationships between those motivations and the experiences of transiting among these different forms of use and non-use. This paper fills that gap by conducting a qualitative interview- and diary-based study... (more)

Efficient Crowd Exploration of Large Networks: The Case of Causal Attribution

Accurately and efficiently crowdsourcing complex, open-ended tasks can be difficult, as crowd participants tend to favor short, repetitive "microtasks". We study the crowdsourcing of large networks where the crowd provides the network topology via microtasks. Crowds can explore many types of social and information networks, but we focus on the...

#pray4victims: Consistencies in Response to Disaster on Twitter

This paper studies commonalities in response across disasters in online social networks (OSNs), specifically Twitter. After presenting an algorithm for extracting vocabularies across disasters, we extract type-specific vocabularies for terrorist attacks, earthquakes, and climate-related disasters between 2012 and 2017. Disaster type drives... (more)

Supporting Collaboratively Constructed Independence: A Study of Spinal Cord Injury

Independence is a central concern for people in the care of many chronic conditions. It is often viewed as a goal that can be facilitated with the use... (more)

Investigating Crowd Creativity in Online Music Communities

Crowd creativity is typically associated with peer-production communities focusing on artistic products like animations, video games, and music, but... (more)


Proceedings of the ACM on Human Computer Interaction (HCI) is a journal for research relevant to multiple aspects of the intersection between human factors and computing systems. Characteristics of humans from individual cognition, to group effects, to societal impacts shape and are shaped by computing systems. Human and computer interactions affect multiple aspects of daily life, shape mass social changes, and guide novel computing experiences. These interactions are studied via multiple methods, including ethnography, surveys, experiments, and system implementation among others. PACMHCI covers a broad range of topics and methods that help illuminate the intersection between humans and computing systems. The scope of this journal includes research contributions in new systems for input and output, studies of user experiences with computing systems, scholarship on the individual and group effects of computer mediation, and societal impacts of new human computer interactions. PACMHCI also welcomes contributions on new methodologies, tools, theories and models, as well as visionary and survey papers that help advance the field.
