- Conference PosterBlockchain 4 Education(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Kolvenbach, Sabine; Ruland, Rudolf; Gräther, Wolfgang; Prinz, WolfgangCertificates play an important role in education and companies, where individual learning records become essential for people’s professional careers. It is therefore important that these records are stored in long-term available and tamper-proof ledgers. Until today, training facilities, educational institution or certification authorities issue paper-based certificates and certification processes are not digitized. Blockchain technology could support this transformation form paper certificates to digital certificates and it could help to generate learning histories. In this demonstration, we present the Blockchain for Education platform as a practical solution for issuing, monitoring, validating and sharing of certificates. The Blockchain for Education platform is based on the Ethereum blockchain and it uses smart contracts to support the certification process.
- Conference PosterLacomo: A Layer to Develop Collaborative Mobile Applications(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Pichiliani, Mauro Carlos; Dewan, Prasun; Hirata, Celso MassakiNowadays, there is little support for developers to transform single user applications to collaborative ones in the mobile domain. We present Lacomo, a new software layer to build collaborative mobile applications with accessibility, screen sharing, and application rewriting technologies that reduce costs to prototype collaboration features, thereby increasing the range of supported applications without deep application knowledge. We comparing it to an ad hoc approach. Users using Lacomo performed a testing task faster, with less effort and errors at a higher completion time.
- Conference PosterLABORe: Collaborative Assessment of Work-Disruptive Technologies(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Lima, Yuri; de Souza, Jano MoreiraThere are several examples of a crowd collaborating to help experts such as citizen science and human sensoring. In this paper, we present LABORe, one of such efforts, a crowd-based system for the collaborative assessment of work-disruptive technologies. Our goal is to present the prototype of the system – the result of the first cycle of the Soft Design Science Research methodology – and to propose an evaluation methodology to test this system with the help of the ECSCW attendants.
- Conference PosterFostering the appropriation of socially collaborative technologies as a strategy to tackle third-level digital divide(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Bettega, Mela; Teli, MaurizioFinding perspectives that contrast the traditional digital divide literature aiming at «bridging the technology gap», is increasingly common. In this paper, we introduce the case of Madeira, a small Portuguese island characterised by low-pace digitisation and significant socioeconomic unbalance. Through this example, we hypothesize that in a close future, facing the spread of ICT use, a lower-educated population may underestimate the downsides of capitalistic digital tools adoption. Nevertheless, we also introduce the idea that scarcely digitised environment may constitute privileged location where to facilitate the spread of socially collaborative technologies.
- Conference PosterExtending the Gmail User-Interface to Leverage Prediction of Response Times and Hierarchical Recipients(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Li, Danwei; Bartel, Jacob; Dewan, PrasunRecent work has shown how the Gmail user-interface can be extended to make use of algorithms for predicting a flat list of email recipients. We build on this work by addressing how this user-interface be extended to make use of external algorithms for predicting (a) a hierarchical list of email recipients, and (b) the expected time to get a response from a recipient. We have augmented the existing view for sending messages to allow users to view predictions of response times and hierarchical recipients, and use one click to select a subgroup of predicted recipients. We have also added new folder- specific commands to the views for browsing folders that allow users to use one click to highlight, un-highlight, and select messages whose responses have not arrived or been sent within the predicted times. We have also developed a new configuration view for determining which predictions should be displayed and how often new training data should be used to change the prediction model. The user-interface is implemented as a Chrome extension that communicates with an external server to receive predictions and send training data. This architecture decouples the implementation of the user-interface and algorithms. However, our extension is intimately tied to the extended user-interface, as it reads and augments existing views and menus of Gmail.
- Conference PosterThe Role of Culturally Intelligent Team Leaders on Task Performance(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Pacheco, Dulce; Stevens, ScottWorkforces are becoming increasingly more diverse, as they function in disciplinary and culturally diverse environments. There is a growing need for effective leadership in these settings. Research shows that cultural values influence both role expectations and perceptions of role expectations and correlate to poor performance evaluations. We hypothesize that leaders with a better understanding of cultural values would lead their teams to higher task performance. A study was conducted with a sample of 19 students, all team leaders working in a project-based class for one semester in a disciplinary and culturally diverse graduate program. Cultural intelligence or cultural quotient (CQ) was measured by the Cultural Intelligence Scale (CQS) and experts evaluated team task performance. Results indicate that Cognitive CQ and Motivational CQ positively correlate to task performance. The outcomes of this study can be used in the selection, training, and development of leaders of culturally diverse teams.
- Conference PosterThe Influence of the Leaders’ Selection Method on Team Performance(Proceedings of 16th European Conference on Computer-Supported Cooperative Work - Panels, Posters and Demos, 2018) Pacheco, Dulce; Soares, LuísaLeadership impacts team performance. More effective leadership at the workplace may improve team performance and, consequently, increase both employees and employers work satisfaction. There is a wide array of studies on effective leadership, but the influence of the way the leader is select on team performance and is not yet clear. We discuss the relationship between the methods used to select the leader and team performance. A study was conducted with a sample of 112 bachelor students working in 17 teams during an 8-week long class project. Team performance was measured by the sub- scale Perceived Team Collaboration of the instrument Team Collaborator Evaluator (TCE) and also by the final project grade given by the instructors. Results show that teams have higher performances when their members unanimously choose the leader. Practical implications for the selection of team leaders are discussed.
