Computer-mediated communication (CMC) has become the new normal in the era of pandemic-induced physical distancing. CMC has dramatically reduced business travel and daily commuting for knowledge workers able to work from home, which in turn reduces carbon emissions and energy expenditure. CMC offers a different communication experience compared to in-person interactions, and its impact on the success of communication is complex. Here, we report the Communication Objectives Model (COM), a framework developed to: a) understand differences in the performance of communication objectives between CMC and face-to-face interactions, and b) guide future research on measurement of such communication objectives. Given that ...

An Investigation Of Barriers And Facilitators To Living Kidney Donation, Rachel E. Crenshaw 2021 University of Louisville

An Investigation Of Barriers And Facilitators To Living Kidney Donation, Rachel E. Crenshaw

Electronic Theses and Dissertations

There is strong interest in increasing living kidney donation, as the need for kidney transplants is quite high. Although previous studies outline some barriers and facilitators associated with donating, living kidney donation comprises only a small percentage of overall kidney transplants and thus further research on factors influencing the decision to donate is needed to find ways to increase the donor pool. Ten semi-structured interviews of living kidney donors were completed and analyzed for common themes that either support the current literature or surface additional barriers and facilitators. In addition, a systematic review and analysis of social medial support groups ...

This study examines employees’ training, years of experience, and performance to gauge any correlations among these variables in the area of hazard awareness. The goal of this study is to help individuals to recognize blind spots in their knowledge to identify ...


The Effectiveness Of Locomotion Interfaces Depends On Self-Motion Cues, Environmental Cues, And The Individual, Jonathan W. Kelly, Stephen B. Gilbert 2021 Iowa State University

The Effectiveness Of Locomotion Interfaces Depends On Self-Motion Cues, Environmental Cues, And The Individual, Jonathan W. Kelly, Stephen B. Gilbert

Industrial and Manufacturing Systems Engineering Publications

The proliferation of locomotion interfaces for virtual reality necessitates a framework for predicting and evaluating navigational success. Spatial updating—the process of mentally updating one’s self-location during locomotion—is a core component of navigation, is easy to measure, and is sensitive to common elements of locomotion interfaces. This paper highlights three factors that influence spatial updating: body-based self-motion cues, environmental cues, and characteristics of the individual. The concordance framework, which characterizes locomotion interfaces based on agreement between body movement and movement through the environment, serves as a useful starting point for understanding the effectiveness of locomotion interfaces for enabling ...
