Sexual exploration is a natural part of adolescent development; yet, unmediated internet access has enabled teens to engage in a wider variety of potentially riskier sexual interactions than previous generations, from normatively appropriate sexual interactions to sexually abusive situations. Teens have turned to online peer support platforms to di...

Gender diversity in open source software development continues to be a topic of growing interest among researchers, practitioners, and organizations. To date, research has revealed disparities in participation between developers on the basis of gender, with women being significantly underrepresented in open source development. Using a large data se...

In this study, we explore the future of work by examining differences in productivity when teams are composed of only humans or both humans and machine agents. Our objective was to characterize the similarities and differences between human and human–machine teams as they work to coordinate across their specialized roles. This form of research is i...

It is widely understood that diffusion of and simultaneous interactions between narratives -- defined here as persistent point-of-view messaging -- significantly contributes to the shaping of political discourse and public opinion. In this work, we propose a methodology based on Multi-Variate Hawkes Processes and our newly-introduced Process Influe...

Since the start of coronavirus disease 2019 (COVID-19) pandemic, social media platforms have been filled with discussions about the global health crisis. Meanwhile, the World Health Organization (WHO) has highlighted the importance of seeking credible sources of information on social media regarding COVID-19. In this study, we conducted an in-depth...

The modern information environment provides an opportunity for cognitive engineering to inform the study of information operations, which involve strategic, often politically-motivated actions to manipulate a targeted audience. In this paper we integrate interdisciplinary theoretical concepts to provide a foundation for a model of persuasion in inf...

Recent advances in uncertainty visualization research have focused not only on design features to support decision making, but also on challenges of evaluating the effectiveness of uncertainty visualizations, such as the degree to which individuals’ baseline task comprehension may alter their performance on experimental tasks regardless of a visual...

This paper describes an approach integrating cognitive engineering with computational social science in the context of open source software (OSS) development. Through an analysis of large-scale collaborations in a complex operational setting, we study how expertise and task complexity predict changes in productivity when knowledge loss occurs. Usin...

This study examined how human-robot interaction is influenced by individual differences in theory of mind ability. Participants engaged in a hallway navigation task with a robot over a number of trials. The display on the robot and its proxemics behavior was manipulated, and participants made mental state attributions across trials. Participant abi...

Empirical evaluations of uncertainty visualizations often employ complex experimental tasks to ensure ecological validity. However, if training for such tasks is not sufficient for naïve participants, differences in performance could be due to the visualizations or to differences in task comprehension, making interpretation of findings problematic....

This study investigated how humans interact socially with robots. Participants engaged in a hallway navigation task with a robot. Throughout twelve trials, the display on the robot and its proxemics behavior was varied while participants were tasked with first, reacting to the robot’s actions and second, interpreting its behavior. Results indicated...

As a result of fundamental changes in organizational needs and practices, social coding, a facet of modern collaboration, has become a prevalent phenomenon in software development. While the adoption of social media platforms for social coding, like GitHub, has enabled distributed, asynchronous collaboration among software developers, the structure...

Traditional studies in uncertainty visualization often require naive participants to complete complex, domain-specific tasks in order to examine how effectively a visualization conveys uncertainty to support decision making. However, without assessing whether participants understand such tasks, it can be difficult to determine whether differences i...

Environmental sustainability has grown as a topic of interest in the scientific community and has gained mainstream attention. This paper focuses on issues to consider when designing and assessing the effectiveness of virtual reality (VR) as persuasive technology. We propose a set of research guidelines to inform future work on how to enhance VR’s...
