Sharing Economy: A Business Perspective
2020
The developments in information technology on the one hand, and the reduced purchasing power of many people due to the global crisis as well as the increasing sustainability concerns on the other hand, have contributed in recent years to the creation of a multitude of Internet-enabled peer-to-peer platforms and the consequent rise of a new paradigm of economy, namely the sharing economy. Under this paradigm, consumers on a massive scale share and make use of underutilized resources upon payment. In this chapter, we present an overview of the sharing economy phenomenon from a business perspective by identifying the major factors guiding its emergence and growth, by presenting some important …
How Are Situation Picture, Situation Awareness, and Situation Understanding Discussed in Recent Scholarly Literature?
2019
There are several different definitions of situation awareness. However, all of them have in common is knowing and understanding of what is happening, an understanding of future changes or problems, and the prediction of the future situation and the decisions to be made on its basis. Situation picture and Situation Awareness are narrow. Situation understanding of the situation is the understanding of the decision-makers and their assistants about what has happened, the circumstances that have affected them, the goals of the different parties and the possible development options of the events needed to make decisions on a particular issue or subject. The results of this study indicate that t…
Extending the semiotics of embodied interaction to blended spaces.
2015
In this paper, we develop a new way of understanding interactions in blended spaces. We do this by developing ideas about embodied semiotics and then apply these ideas to the analysis of interaction in mixed-reality blended spaces (where the physical world and digital world are blended deliberately to provide new forms of interaction). We discuss how blended spaces provide a new medium within which people have experiences. The semiotic analysis reveals how blended spaces are constructed across the physical and the digital, highlighting the ontology, topology, volatility, and agency present within them. It shows how people move between the physical and digital spaces through the objects and …
DETECTING FALLS AT HOME: USER-CENTERED DESIGN OF A PERVASIVE TECHNOLOGY
2016
Falling is the main cause of domestic accidents and fatal injuries to seniors at home. In this paper, we describe the design process for a new pervasive technology (CIRDO). The aim of this technology is to detect falls (via audio and video sensors) and to alert the elderly's family or caregivers. Two complementary studies were performed. Firstly, the actual risk situations of older adults were analyzed. Secondly, social acceptance was investigated for the different homecare field stakeholders. Our results highlight the tensions among social actors towards the tool and their impacts on technology acceptance by the elderly. Also, we show a significant change in the fall process due to the dev…
The individuals’ interest in preventing everyday accidents and crises : A Swedish explorative study of the importance of motivation
2014
This explorative study presents an empirical examination of the connection between motivation and the measures individuals take to prevent everyday accidents and prepare for crises. Positional factors (age and gender) and situational factors (education, size of locality, and household composition) are included because the literature highlights their importance. The study used data gathered in a 2010/2011 poll of randomly selected Swedish residents aged 16–75 (N = 2000; 44.8% response rate). A factor analysis reduced the theoretical model for situational motivation (Guay, Vallerand, & Blanchard, 2000) from four to two dimensions: motivation and amotivation. Subsequent regression analyses sta…
Why Study Online in Upper Secondary School? Qualitative Analysis of Online Learning Experiences
2015
In Finland, online learning has become more common in recent years. In this study, we examined why adult students chose to study online for upper secondary school. The research also focused on the support needed for learning from a special education perspective. Both qualitative and quantitative data were collected using an electronic questionnaire. In total, 58 students responded. Data were analyzed qualitatively using the content analysis technique. The findings indicate that the main reasons for online studies are similar in Finland to those found internationally: flexibility of timetables, the student’s health condition, and family situations. The findings also indicate that a student’s…
Codesigning technology for a voluntary-sector organization
2019
© 2019 Khushnood Naqshbandi, Simon Hoermann, David Milne, Dorian Peters, Benjamin Davies, Sophie Potter, & Rafael A. Calvo. This paper presents an investigation into the experiences and perceptions of volunteers and community managers of an Australian voluntary-sector organization that supports young help-seeking people. The process focused specifically on the design of a chat tool, a rudimentary version of which was conceptualized and tested during a trial completed prior to this study. The process explored the motivations and experiences of these volunteers using a codesign approach, which led to the development of specific features of the chat tool that were tailored to the nature of the…
Help! Is my Chatbot Falling into the Uncanny Valley? : An Empirical Study of User Experience in Human-Chatbot Interaction
2019
Original article available at http://dx.doi.org/10.17011/ht/urn.201902201607 Advances in artificial intelligence strengthen chatbots’ ability to resemble human conversational agents. For some application areas, it may be tempting not to be transparent regarding a conversational agent’s nature as chatbot or human. However, the uncanny valley theory suggests that such lack in transparency may cause uneasy feelings in the user. In this study, we combined quantitative and qualitative methods to investigate this issue. First, we used a 2 x 2 experimental research design (n = 28) to investigate effects of lack in transparency on the perceived pleasantness of the conversation in addition to percei…

The impact of communicating digital technologies: How information and communication technology journalists conceptualize their influence on the audie…
2012
Information technology is ever-changing. Information and communication technology (ICT) journalists play a significant part in diffusing, explaining and interpreting these new technologies and in forging the societal understanding of future trends, influencing both their audience and the developers they cover. They are important gatekeepers and their coverage is – most likely – decisive for the success or failure of new products. To explore this function of ICT journalism, an online survey of 102 ICT journalists in Germany was conducted, including 32 journalists in managing roles. This study focuses on two research questions: (a) how do ICT journalists perceive their relationship to and the…
