“Happy Rides Are All Alike; Every Unhappy Ride Is Unhappy in Its Own Way”: Passengers’ Emotional Experiences while Using a Mobile Application for Ride-sharing
Peking University, China, People's Republic of
Ride-sharing is a rising approach that provides more convenience and flexibility for road users. Previous research has examined the process, existing forms, and matching algorithms of real-time dynamic ride-sharing technology, but we know little about how users feel when they use a ride-sharing application. In this paper, we describe a study that investigates passengers’ emotional experiences when us-ing a ride-sharing application and examines factors related to passengers’ emo-tional experiences. We conducted a survey with 1,129 users of a major ride-sharing app from four cities in China. Results show that: (1) passengers feel more positive emotional experiences (75%) such as “satisfaction” (47%) than negative emotions; (2) negative emotional experiences (worry, disappointment, anger) differ from each other in causal agency, emotional outlet, and action ten-dency; (3) context of use, interaction, and user characteristics are related to pas-sengers’ emotional experiences. The results provide some preliminary under-standing of the passengers’ emotional experiences, and could be helpful to im-prove the design of such socio-technical solutions.
From Paper Forms to Electronic Flowsheets: Documenting Medical Resuscitations in a Time of Transition

Electronic Health Records (EHRs) have a critical role in supporting continuity of patient care and effective clinical decision-making. Although EHRs are widespread today, many emergency departments (EDs) have been slow in adopting them for documenting time-critical scenarios such as resuscitations. Introduction of an electronic flowsheet for documenting medical resuscitations at our research site provided a unique opportunity for studying the nuances of the transition from paper to electronic documentation. We observed 44 medical resuscitations and conducted post-event interviews with 24 nurse documenters to examine their interactions and behaviors with the newly implemented electronic flowsheet. While our findings showed many advantages of electronic documentation, such as improved access to patient records and auto-population of flowsheet sections, we also identified several challenges associated with the flowsheet navigation, technical issues, and lack of practice and use opportunities. We observed different workarounds used by nurse documenters to overcome these challenges, including the use of paper-based mechanisms, free-text fields, and simultaneous documentation by two nurses. Based on our findings, we provide design guidelines for improving the electronic flowsheet to support its use during resuscitations.
Firefighters’ Strategies for Processing Spatial Information During Emergency Rescue Searches

Firefighters face a unique wayfinding situation when they are in emergency situations. This study aims to examine the strategies that firefighters use when in an emergency situation with the goal being to use these insights in future research. In this study, we interview 12 firefighters from around the USA about the methodologies they use when in an emergency situation. After analyzing the results using grounded theory as a basis, we found that firefighters around the country use similar rules that allow them to either 1) build a path 2) use visual aids 3) use cognitive strategies and 4) use directional aids. From here, we hope we can link these strategies to actual tools that can help firefighters save lives.
