, the brain is particularly sensitive to anoxia. The most critical problem for the anoxic brain is thought to be the matching of energy consumption with energy production. In the absence of oxygen, ATP can be produced only through anaerobic glycolysis, which yields about 8 % of the ATP produced from each mole of glucose during aerobic metabolism (Hochachka(More)
In the future, application mobility can play a crucial role and prove to be an enabler for next generation distributed applications. Application mobility lets an application follow the users while they roam between networks using several devices. In order to achieve seamless application mobility, several issues need to be considered such as device(More)
New mobile networks and new devices like smartphones and tablets are rapidly changing opportunities for public sector units delivering smart, mobile e-services to their citizens. Moreover, the upcoming HTML5 standard allows for cross-device and cross-browser support making service development and deployment much more easier than before at lower costs. This(More)
Application mobility is achieved when migrating an application with its code, states and all related information from one device to another during its execution. As traditional applications are being challenged by apps, we believe it is time to rethink the notion of application mobility and explore the concept from a web perspective. More specifically, this(More)
Services based on new information technology offering audio and video modality are viewed among the most important today. When users change location or device there is a need to keep these media sessions active. The main purpose of this article is to present a lightweight framework that allows session mobility through making profit of the cloud and(More)
The e-service area is faced with unique challenges and opportunities as a new mobile IT-landscape emerges. Technical challenges such as heterogeneous devices and networks, scalability and ability to deliver e-services anytime, anywhere to the users must be met with the careful design of functional application platforms and means of distributing e-services(More)
Like Nelson (2002), I make a case for bringing institutions into evolutionary economics. But unlike Nelson, who defines institutions as social technologies consisting of rules-routines, I define them in agreement with North (1990) as humanly devised rules-constraints — such as formal law and informal social norms — but also view them, to accommodate most of(More)
Mobility exists in many shapes; when migrating a running application (code, states and data) from one device to another, one has achieved application mobility. In this article we combine this mobility type with context awareness, defining context awareness supported application mobility (CASAM) as when using context in the act of moving an application(More)
In this paper we present a case study of a location-dependent service, aimed for tourists. Two applications are developed, one based on native technologies, the other on HTML5 and related frameworks. We provide implementation details and compare the different solutions in terms of location support, compliance with required features, and cross-platform(More)
Purpose – The purpose of this paper is to investigate the importance of the entrepreneur’s quest for independence and control over the firm for governance and financing strategies with a special focus on family firms and how they differ from nonfamily firms. Design/methodology/approach – The analysis is based on 1,000 telephone interviews with Swedish micro(More)
