Chasing the Chatbots: Directions for Interaction and Design Research

Big tech-players have been successful in pushing the chatbots forward. Investments in the technology are growing fast, as well as the number of users and applications available. Instead of driving investments towards a successful diffusion of the technology, user-centred studies are currently chasing the popularity of chatbots. A literature analysis evidences how recent this research topic is, and the predominance of technical challenges rather than understanding users’ perceptions, expectations and contexts of use. Looking for answers to interaction and design questions raised in 2007, when the presence of clever computers in everyday life had been predicted for the year 2020, this paper presents a panorama of the recent literature, revealing gaps and pointing directions for further user-centred research

Managing innovation in English language education, state of the art review.

Innovation in English language education (ELE) has become a major ‘growth area’ in recent years. At the same time, an ELE innovation management literature has also developed, based on insights from innovation theory and their application, both from outside and within ELE, and concerned with attempting to critically evaluate and inform ELE innovation practice. Thus, using a well-established three-part framework for distinguishing the main stages involved in innovation project management, this review describes and discusses the main features of this body of work. After defining terms and clarifying its scope, it considers what is said about the innovation ‘initiation’ phase, in terms of innovation causes, characteristics and contexts. It then examines conceptualisations of the innovation ‘implementation’ stage, by distinguishing main overall approaches, frameworks for identifying and configuring roles, underlying psychological processes, and the use of evaluation techniques. Lastly, the literature relating to innovation ‘institutionalisation’ stage is analysed. The article concludes by identifying overall trends and areas for further development. In particular, it is argued that ELE innovation work needs to become more informed by many of the concepts and procedures which the ELE innovation management literature contains

Dynamics of Information Distribution on Social Media Platforms during Disasters

abstract: When preparing for and responding to disasters, humanitarian organizations must run effective and efficient supply chains to deliver the resources needed by the affected population. The management of humanitarian supply chains include coordinating the flows of goods, finances, and information. This dissertation examines how humanitarian organizations can improve the distribution of information, which is critical for the planning and coordination of the other two flows. Specifically, I study the diffusion of information on social media platforms since such platforms have emerged as useful communication tools for humanitarian organizations during times of crisis. In the first chapter, I identify several factors that affect how quickly information spreads on social media platforms. I utilized Twitter data from Hurricane Sandy, and the results indicate that the timing of information release and the influence of the content’s author determine information diffusion speed. The second chapter of this dissertation builds directly on the first study by also evaluating the rate at which social media content diffuses. A piece of content does not diffuse in isolation but, rather, coexists with other content on the same social media platform. After analyzing Twitter data from four distinct crises, the results indicate that other content’s diffusion often dampens a specific post’s diffusion speed. This is important for humanitarian organizations to recognize and carries implications for how they can coordinate with other organizations to avoid inhibiting the propagation of each other’s social media content. Finally, a user’s followers on social media platforms represent the user’s direct audience. The larger the user’s follower base, the more easily the same user can extensively broadcast information. Therefore, I study what drives the growth of humanitarian organizations’ follower bases during times of normalcy and emergency using Twitter data from one week before and one week after the 2016 Ecuador earthquake.Dissertation/ThesisDoctoral Dissertation Business Administration 201
