Report on the Information Retrieval Festival (IRFest2017)
The Information Retrieval Festival took place in April 2017 in Glasgow. The focus of the workshop was to bring together IR researchers from the various Scottish universities and beyond in order to facilitate more awareness, increased interaction and reflection on the status of the field and its future. The program included an industry session, research talks, demos and posters as well as two keynotes. The first keynote was delivered by Prof. Jaana Kekalenien, who provided a historical, critical reflection of realism in Interactive Information Retrieval Experimentation, while the second keynote was delivered by Prof. Maarten de Rijke, who argued for more Artificial Intelligence usage in IR solutions and deployments. The workshop was followed by a "Tour de Scotland" where delegates were taken from Glasgow to Aberdeen for the European Conference in Information Retrieval (ECIR 2017
Persuasive design of a mobile energy conservation game with direct feedback and social cues
Pervasive gaming has the potential of transforming the
home into a persuasive environment in which the user can
learn about appliances and their electricity consumption.
Power Explorer is a mobile game with a special sensing
approach that provides real-time electricity measurements
and feedback when the user switches on and off devices in
the home. The game was developed based on persuasive
principles to provide an engaging means to learn about
energy with positive and negative feedback and social
feedback from peers on real energy actions in the home. We
present the design and rationale of this game and discuss
how pervasive games can be viewed from a persuasive and
learning point of view

#Bigbirds never die: Understanding social dynamics of emergent hashtag
We examine the growth, survival, and context of 256 novel hashtags during the 2012 U.S. presidential debates. Our analysis reveals the trajectories of hashtag use fall into two distinct classes: âwinnersâ that emerge more quickly and are sustained for longer periods of time than other âalso-ransâ hashtags. We propose a âconversational vibrancyâ framework to capture dynamics of hashtags based on their topicality, interactivity, diversity, and prominence. Statistical analyses of the growth and persistence of hashtags reveal novel relationships between features of this framework and the relative success of hashtags. Specifically, retweets always contribute to faster hashtag adoption, replies extend the life of âwinnersâ while having no effect on âalso-rans.â This is the first study on the lifecycle of hashtag adoption and use in response to purely exogenous shocks. We draw on theories of uses and gratification, organizational ecology, and language evolution to discuss these findings and their implications for understanding social influence and collective action in social media more generally

Development of a game-based learning tool for applied team science communication in a virtual clinical trial.
Educational tools for application of team science competencies in clinical research are needed. Our interdisciplinary group developed and evaluated acceptability of a virtual world game-based learning tool simulating a multisite clinical trial; performance hinges on effective intrateam communication. Initial implementation with clinical research trainees (n=40) indicates high satisfaction and perceived relevance to team science and research career goals. Game-based learning may play an important role in team science training
Building an excellent foundation for research: Challenges and current research needs
The delivery of research-informed education is a fundamental principle held by universities and is a principle that work-integrated education (WIL) should not be exempt from. In the 1980s and 1990s, critical reviews of the WIL literature suggested WIL research required significant development. Since these reviews were conducted a significant, well-developed body of literature has formed and increasingly WIL models of delivery are relying on research findings to inform program design. However, despite these successes, significant challenges and research gaps still exist. Authors in this APJCE special issue have given attention to a number of areas that present as challenges. The area of negative and neglected research findings are highlighted and the reexamining the nature of the relationship between the student and workplace supervisor has been discussed. A model of enabling transformative learning is presented and an investigation of the influence of WIL experiences on undergraduate student study direction choices has been reported. Other areas in need of further research attention are also discussed
