Prototyping Futures
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Prototyping Futures gives you a glimpse of what collaborating with academia might look like. Medea and its co-partners share their stories about activities happening at the research centre – projects, methods, tools, and approaches – what challenges lie ahead, and how these can be tackled. Examples of highlighted topics include: What is a living lab and how does it work? What are the visions behind the Connectivity Lab at Medea? And, how can prototyping-methods be used when sketching scenarios for sustainable futures? Other topics are: What is the role of the body when designing technology? What is collaborative media and how can this concept help us understand contemporary media practices? Prototyping Futures also discusses the open-hardware platform Arduino, and the concepts of open data and the Internet of Things, raising questions on how digital media and connected devices can contribute to more sustainable lifestyles, and a better world.

- Firms face opposing incentives regarding when to take strategic decisions towards their exploration ventures. On the one hand, postponing can reduce uncertainty, but on the other, moving quickly allows capitalizing on a potential competitive advantage. Drawing on theories of entrepreneurship and real options reasoning, we suggest that firms resolve the competing tensions for acceleration and deceleration through an assessment of their venture portfolio and environment. An empirical study of the timing of termination and exploitation decisions taken with regard to 3,272 exploration ventures in Australia’s mining industry over the years 2002-2011 provides an insight into the drivers of decision timing. We find that venture portfolio composition is an important driver of timing— but only with regard to exploitation decisions. Higher levels of market uncertainty increase the time to venture termination but not exploitation, and a positive market trajectory increases the time to venture termination, yet decreases the time to exploitation. Finally, we find support for interaction effects between the portfolio and market. The overall pattern of findings sheds new light on the tension between deceleration and acceleration in entrepreneurial strategic decision making and highlights the importance of distinguishing between the timing of different types of decisions.

- Firms face opposing incentives regarding when to make strategic decisions about their exploration ventures. On the one hand, postponing a decision can reduce uncertainty, while on the other hand, moving quickly allows one to capitalize on favorable market conditions. Drawing on theories of entrepreneurship, real options reasoning, and decision speed, we suggest that firms resolve competing tensions between acceleration and deceleration through an assessment of their venture portfolio and environment. An empirical study of the timing of termination and exploitation decisions regarding 3,272 exploration ventures in Australia’s mining industry over the years 2002–2011 provides insights into the drivers of decision timing. We find that venture portfolio composition is an important driver of timing but only with regard to exploitation decisions. Higher levels of market uncertainty increase the time to venture termination but not exploitation, and a positive market trajectory increases the time to venture termination yet decreases the time to venture exploitation. We also find support for an interaction effect between the portfolio and market characteristics. This pattern of findings sheds light on the tension between acceleration and deceleration in strategic decision making and highlights the importance of distinguishing between the timing of different types of decisions.

Forskningsöversikt (refereegranskat)abstract
- A wealth of knowledge on the life and death of human neutrophils has been obtained by the in vitro study of isolated cells derived from peripheral blood. However, neutrophils are of main importance, physiologically as well as pathologically, after they have left circulation and transmigrated to extravascular tissues. The journey from blood to tissue is complex and eventful, and tissue neutrophils are in many aspects distinct from the cells left in circulation. Here we describe how to obtain human tissue neutrophils in a controlled experimental setting from aseptic skin lesions created by the application of negative pressure. One protocol enables the direct analysis of the blister content, infiltrating leukocytes as well as exudate fluid, and is a simple method to follow multiple parameters of aseptic inflammation in vivo. Also described is the skin chamber technique, a method based on denuded skin blisters which are subsequently covered by collection chambers filled with autologous serum. Although slightly more artificial as compared to analysis of the blister content directly, the cellular yield of this skin chamber method is sufficient to perform a large number of functional analyses of in vivo transmigrated cells.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present paper is to share our experience in battery safety testing and risk analysis from arecent project called BLIXT, which had the objective to speed up the progress of the paradigmatic shifttoward electric vehicles (EV). The batteries in question have been three different configurations of lithiumionbatteries (LiFePO4). The tests have involved fire, crash tests and sort circuit.
