On Grief and Grieving: Finding the Meaning of Grief through the Five Stages of Loss

We consider social media as a promising tool for public health, focusing on the use of Twitter posts to build predictive models about the forthcoming influence of childbirth on the behavior and mood of new mothers. Using Twitter posts, we quantify postpartum changes in 376 mothers along dimensions of social engagement, emotion, social network, and linguistic style. We then construct statistical models from a training set of observations of these measures before and after the reported childbirth, to forecast significant postpartum changes in mothers. The predictive models can classify mothers who will change significantly following childbirth with an accuracy of 71%, using observations about their prenatal behavior, and as accurately as 80-83% when additionally leveraging the initial 2-3 weeks of postnatal data. The study is motivated by the opportunity to use social media to identify mothers at risk of postpartum depression, an underreported health concern among large populations, and to inform the design of low-cost, privacy-sensitive early-warning systems and intervention programs aimed at promoting wellness postpartum.

Predicting postpartum changes in emotion and behavior via social media

Crowdfunding sites like Kickstarter--where entrepreneurs and artists look to the internet for funding--have quickly risen to prominence. However, we know very little about the factors driving the 'crowd' to take projects to their funding goal. In this paper we explore the factors which lead to successfully funding a crowdfunding project. We study a corpus of 45K crowdfunded projects, analyzing 9M phrases and 59 other variables commonly present on crowdfunding sites. The language used in the project has surprising predictive power accounting for 58.56% of the variance around successful funding. A closer look at the phrases shows they exhibit general persuasion principles. For example, also receive two reflects the principle of Reciprocity and is one of the top predictors of successful funding. We conclude this paper by announcing the release of the predictive phrases along with the control variables as a public dataset, hoping that our work can enable new features on crowdfunding sites--tools to help both backers and project creators make the best use of their time and money.

The language that gets people to give: phrases that predict success on kickstarter

LGBTQ+ (lesbian, gay, bisexual, transgender, queer) individuals are at significantly higher risk for mental health challenges than the general population. Social media and online communities provide avenues for LGBTQ+ individuals to have safe, candid, semi-anonymous discussions about their struggles and experiences. We study minority stress through the language of disclosures and self-experiences on the r/lgbt Reddit community. Drawing on Meyer's minority stress theory, and adopting a combined qualitative and computational approach, we make three primary contributions, 1) a theoretically grounded codebook to identify minority stressors across three types of minority stress-prejudice events, perceived stigma, and internalized LGBTphobia, 2) a machine learning classifier to scalably identify social media posts describing minority stress experiences, that achieves an AUC of 0.80, and 3) a lexicon of linguistic markers, along with their contextualization in the minority stress theory. Our results bear implications to influence public health policy and contribute to improving knowledge relating to the mental health disparities of LGBTQ+ populations. We also discuss the potential of our approach to enable designing online tools sensitive to the needs of LGBTQ+ individuals.

The Language of LGBTQ+ Minority Stress Experiences on Social Media

Videoconferencing (VC) is a type of online meeting that allows two or more participants from different locations to engage in live multi-directional audio-visual communication and collaboration (e.g., via screen sharing). The COVID-19 pandemic has induced a boom in both private and professional videoconferencing in the early 2020s that elicited controversial public and academic debates about its pros and cons. One main concern has been the phenomenon of videoconference fatigue. The aim of this conceptual review article is to contribute to the conceptual clarification of VC fatigue. We use the popular and succinct label “Zoom fatigue” interchangeably with the more generic label “videoconference fatigue” and define it as the experience of fatigue during and/or after a videoconference, regardless of the specific VC system used. We followed a structured eight-phase process of conceptual analysis that led to a conceptual model of VC fatigue with four key causal dimensions: (1) personal factors, (2) organizational factors, (3) technological factors, and (4) environmental factors. We present this 4D model describing the respective dimensions with their sub-dimensions based on theories, available evidence, and media coverage. The 4D-model is meant to help researchers advance empirical research on videoconference fatigue.

Videoconference Fatigue: A Conceptual Analysis

People turn to social media to express their emotions surrounding major life events. Death of a loved one is one scenario in which people share their feelings in the semi-public space of social networking sites. In this paper, we present the results of a two-part investigation of grief and distress in the context of messages posted to the profiles of deceased MySpace users. We present coding system for identifying emotion distressed content, followed by a detailed analysis of language use that lays a foundation for natural language processing (NLP) tasks, such as automatic detection of bereavement-related distress. Our findings suggest that in addition to words bearing positive or negative sentiment, linguistic style can be an indicator of messages that demonstrate distress in the space of post-mortem social media content. These results contribute to research in computational linguistics by identifying linguistic features that can be used for automatic classification as well as to research on death and bereavement by enumerating attributes of distressed self-expression in a post-mortem context.

Grief-Stricken in a Crowd: The Language of Bereavement and Distress in Social Media

We investigate self-perception in social media through the lens of personality theory. Two mixed-methods studies involving 148 participants examine if people self-report different personality traits in social media compared with their offline traits. We first compare offline and Facebook traits, finding that on Facebook people are less Neurotic, Open and Agreeable. A second study compared offline, Facebook and Snapchat traits, replicating and extending our initial results. Again Facebook personality was less Neurotic and less Open than offline. In contrast, Snapchat personality was more Extravert than both offline and Facebook and more Open than Facebook. Interviews indicate how personality differences arise from social media affordances. Anxiety about audience judgments leads people to curate posts to appear less Neurotic on social media, but the transience of Snapchat promotes greater Extraversion than offline and Facebook. We discuss theory and design implications.

Terms of Service (ToS) agreements are typically written to satisfy corporate legal requirements rather than user understanding. Users are often deeply dissatisfied with online ToS agreements, which they typically find incomprehensible. Nevertheless, users frequently agree to the ToS, potentially surrendering their data and rights. We therefore designed alternative ways of presenting existing ToS documents using crowdsourced sentiment highlighting, to make documents more readable. This highlighting visualizes different sections of the agreement as positive or negative. We evaluated the visualization, finding that participants recognized highlighted information better, and most participants praised the visualization. We discuss design implications and the next steps for more interactive ToS.

Beyond Avoidance and Passivity: Novel UIs to Make Terms of Service Comprehensible

It is difficult to run long-term in-the-wild studies with mobile robots. This is partly because the robots we, as human-robot interaction (HRI) researchers, are interested in deploying prioritize expressivity over navigational capabilities, and making those robots autonomous is often not the focus of our research. One way to address these difficulties is with the Wizard of Oz (WoZ) methodology, where a researcher teleop-erates the robot during its deployment. However, the constant attention required for teleoperation limits the duration of WoZ deployments, which in-turn reduces the amount of in-the-wild data we are able to collect. Our key insight is that several types of in-the-wild mobile robot studies can be run without autonomous navigation, using wandering instead. In this paper we present and share code for our wandering robot system, which enabled Kuri, an expressive robot with limited sensor and computational capabilities, to traverse the hallways of a $28,000 \text{ ft}^{2}$ floor for four days. Our system relies on informed direction selection to avoid obstacles and traverse the space, and periodic human help to charge. After presenting the outcomes from the four-day deployment, we then discuss the benefits of deploying a wandering robot, explore the types of in-the-wild studies that can be run with wandering robots, and share pointers for enabling other robots to wander. Our goal is to add wandering to the toolbox of navigation approaches HRI researchers use, particularly to run in-the-wild deployments with mobile robots.
