Abstract [en]

This paper explores the current context of collabo­ration between small local food producers. The aim is to facilitate the design and maintenance of trust­worthy collaborative e-marketplaces containing clusters of SMEs. An ethnographic approach was used and data was collected through observations, interviews and questionnaires. Our findings reveal both drivers to exploit and barriers to harness enabling trustworthy collaboration. Our current test bed is based on a research and design context that lacks mechanisms for governance. To take full advantage of the drivers and to tackle the barriers in a fruitful way, there is a need for a flexible infra­structure that allow for structured requirements, contractual agreements and validation of proposed collaboration services. To address this, we take advantage of recent developments in cloud computing, more specifically the integration of Platform as a Service (PaaS) in the support system.

Abstract [en]

This thesis reports a research effort that comprises six papers and a cover paper. In essence, the thesis contributes to the understanding of collaborative settings by introducing the perspective of ‘places of collaboration’. This perspective is particularly important when designing computer-based technologies that support collaborative settings.

 

The starting point and overall research aim is to understand people’s efforts to configure their current context for the purposes of collaboration. The cover paper of the thesis comprises a theoretical reflection and examination of four collaborative settings. The settings have been studied in situ through ethnographic inquiry and the results are reported in the six papers enclosed in the thesis. In my theoretical reflection, the concepts of ‘place’, ‘space’ and ‘boundary objects’ are central.

 

The studies revealed that people’s efforts to configure the current context create and reflect a ‘place of collaboration’. In other words, the effort to configure the context results in a practice characterized by an understanding of how to cooperate; a collaborative practice that constitutes a ‘place of collaboration’. During this configuration, the space and the use of materiality in this space are important parts in the creation of a place of collaboration. In addition, people configure collaborative contexts of intersecting practices by creating boundary objects. Boundary objects serve as mediators in a place-making process for the integration of places into a ‘place of collaboration’ for several practices. What is more, the dynamics of a place of collaboration may affect changes in existing modes of working and in computer-based tools that have been introduced into the workplace. The people and practices that constitute the place will in turn re-configure the place of collaboration, including the space and objects available due to the new circumstances.

 

People’s configuration of their current context reveals crucial aspects about the place of collaboration that must be considered also when designing to support this setting. However, this configuration may not necessarily equal efficiency and effectiveness, as evaluated by actors external to this context. The conclusion of this thesis is that future research and design should consider how to support people in their own effort to configure their collaborative context.

Abstract [en]

In this presentation we will describe the Kamimo project, a two year cooperation (2007-2008) between the University of Kalmar (Sweden), University College Molde (Norway) and Central Missouri University (USA) and sponsored by the Norwegian Open University (Norgesuniversitet). The project aims to investigate the potential uses of virtual worlds in higher education by carrying out a number of courses, projects and collaborative work in Second Life.  The project has established two virtual islands, Kamimo Island and Virtual Montmartre in cooperation with external consultants who have assisted with the building and establishment of the islands.   The main objectives of the project are to:  1) Create a stimulating virtual learning environment in SL   2)  Test and evaluate different teaching and learning activities in SL (courses, projects, meetings, roleplay)   3) Test and evaluate how effectively SL can be used in fostering cooperation (between faculties, universities, business)   4) Test selected learning tools or elements together with the virtual environment  The project supports learning activities for different segments of the partner organizations student populations as well as allowing for cross communication between the student bodies. We have offered two courses in English presentation skills run completely in Second Life, several student projects designing and building virtual environments in SL as part of an ongoing degree program, courses for information technology majors and further integration and testing of the virtual world elements for learning and for support of learning and communication between groups within the business sector. These activities are being evaluated and we aim to present research papers based on the findings at a later date.  Our partners at Central Missouri University have built a simulation of Montmartre, Paris as it was in the 1920s in order to provide students with an engaging and immersive learning environment for studies in Afro-American culture and in particular the growth of jazz in post-WW1 Paris. The use of virtual worlds to facilitate immersive role play and enable students to recreate convincingly the era they are studying is being investigated as part of the project and will be presented at the conference. In the evaluation of the project activities we have focused on examining how far teaching methods used in Second Life exhibit affective support for the involvement of learners. We examine how the use of virtual worlds can add a social dimension to distance learning not present in existing learning management systems.  In this presentation we will describe our reasons for working in Second Life, conclusions based on our teaching experience there, ongoing research and thoughts on the future relevance of virtual worlds in higher education. The presentation will use PowerPoint slides as well as a live demonstration of Second life and a meeting on our own Kamimo Island. Several of the project group will participate via Second life as well as possibly a representative from one of the other universities we have collaborated with over the last year.  The Kamimo project group consists of: Björn Jaeger, University College Molde (Norway) Judith Molka-Danielsen, University College Molde (Norway) Dr. Bryan Carter, Central Missouri University (USA) Alastair Creelman, University of Kalmar (Sweden) David Richardson, University of Kalmar (Sweden)  Project blog - http://kamimo-islands.blogspot.com/
