- The corrosion behavior of magnesium-aluminum (Mg-Al) alloy AM50 produced by a rheocasting (RC) technique was examined in the presence and absence of CO2 at three temperatures -4, 4 and 22 degrees C. The slurry preparation in the RC material was performed with the newly developed RheoMetal process. For reference, 99.97% Mg was included in the corrosion exposures. The influence of the microstructure on the atmospheric corrosion of alloy AM50 produced by RC and high pressure die casting (HPDC) was investigated. The RC AM50 alloy showed better corrosion resistance than HPDC AM50 in all the exposure environments studied. For both materials, there was a strong positive correlation between temperature and the atmospheric corrosion rate. The superior atmospheric corrosion behavior of RC AM50 compared to HPDC AM50 is carefully discussed in relation to differences in the as-cast microstructure. This study demonstrates that producing the alloy AM50 by this type of RC technique opens the door to Mg-Al alloys as a promising candidate for various applications where corrosion resistance is of importance.

- Research has shown that collaboration and co-creation among different groups of stakeholders add complexity and challenges to the innovation process. In this paper a study of co-creation in a multi-stakeholder innovation process is presented. The co-creation is explored and described from a boundary practice perspective. The empirical data presented in the study is based on a user-centric innovation project, Free2Ride, where researchers, developers and members of two equestrian clubs co-created a piece of ICT safety equipment consisting of a transmitter (on the horse) and a receiver (application on a smartphone) to be used by equestrian club members during their everyday riding activities. Three episodes were extracted from the empirical data and presented in the paper. From these episodes the researchers have identified four characteristics of the spanning of boundaries in co-creation from a boundary practice perspective. One of the contributions in the papers is a description of boundary practice-spanning. The research approach adopted in the study is the action case approach.

Konferensbidrag (refereegranskat)abstract
- This paper is based on a user-centric innovation project, Free2Ride, which is seen as an example of community interaction that overcomes boundaries. The Free2Ride projects goal was to develop a piece of ICT safety equipment consisting of a sender (on the horse) and a receiver (application in a smartphone) to be used by equestrian club members during their everyday riding activities. We will answer the research question of what the characteristics of a boundary dialogue in user-centric innovation activities are. The aim of the paper is to propose a model describing the characteristics of boundary dialogue in user-centric innovation that involve different communities of practices such as ICT developers, users and researchers. An important element of that model is the mental wandering, inwards and outwards, by core members in a community. We discuss the temporal as well as the symbolic nature of the mental wandering during the boundary dialogue in user-centric innovation activities. We applied a combination of research approaches consisting of action research and engaged scholarship approach. The theoretical framework for analyzing our findings is communities of practices with a specific interest in boundary spanning and learning dialogues.

Dynamics in an innovation boundary context : exploring a living labprocess from a community of practice perspective

Konferensbidrag (refereegranskat)abstract
- This paper is based on studies of a living lab process, which is an open, user-centric, innovation approach, where several actors from industry, user groups and academia are involved. We aim to describe and analyze the dynamics in an innovation boundary context based on a living lab process. An action-oriented research approach was applied and the empirical results are from The Find Project (TFP), with the aim of customizing an ICT product based on the needs of a user group. The findings are analyzed from a community of practice perspective where the three different communities i) researchers from Halmstad Living Lab (HLL), ii) ICT developers (ICTD), and iii) next of kin's to demented elderly persons (NOKD) represented the units of analysis. The analysis identified several boundary situations that played a vital role for the innovation process. The contribution of our research to innovation theory is a process model describing the dynamics in an innovation boundary context with regard to boundary objects-in-use as well as to brokering. The research highlights two different levels of brokering: i) product/service brokering; and ii) process brokering.

Assessing the business value of electronic order-to-payment cycle
- 2009
-
Ingår i: ECIS 2009 Proceedings.
-
Konferensbidrag (refereegranskat)abstract
- In this paper, we build an evaluation tool for assessing the business impacts of an electronic order-topayment cycle. Based on a literature review and expert interviews, we formulate a three-stage model which includes performance indicators for electronic order, electronic invoice, and electronic payment processes. In addition, we pinpoint the inter-process linkages. We test the proposed evaluation tool in a business context and find that the impacts of automating the order-to-payment cycle relate closely to cost avoidance. However, a strong emphasis on asset utilization can be observed as well – better use of IT could enhance utilization of existing human resources and capital, affecting company profitability.

Attitudes to information technology in health care professions
- 2009

Ingår i: The 17th European Conference on Information Systems, Verona, june 8-10, 2009..

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this paper is to explore attitudes towards IT among various categories of health care staff; health care professions. We will identify problem areas that may be the reasons for why different attitudes among different professions at a healthcare organisation exist, and subsequently we will analyse how this may have impact on how to make sense of IT use. The research question is: What factors may explain differences regarding attitudes to IT among different professions in a health care organisation?The paper reports from a particular study of the “NU” healthcare organisation in west Sweden. The results reveal two main problem areas: i) the infrastructural and; ii) the socio-organisational. These are discussed as analytical implications for bridging the gaps between different professions in health care organisations.

From Tutor to Producer : Changes in the design space of online education
- 2010

Ingår i: Proceedings of the 33rd IRIS Seminar. 2010.. - Rebild, Denmark.

Konferensbidrag (refereegranskat)abstract
- In recent years online and blended learning has scaled up from being a pilot endeavour driven by pioneers, to constituting a large portion of many institutions of higher education. In the process, the conditions for the online teacher has gradually changed, and the situation of today is in many ways problematic where student interaction and dialogue has to stand back in favour of time consuming content production, material delivery, and technical problem solving. This paper draws on the experiences from a Scandinavian University to illustrate how this transition can be understood in the light of rapid technological development in combination with slow evolution of pedagogical models for online education.
