Which senses dominate at different stages of product experience?
In the area of product design, sensory dominance can be defined as the relative importance of different sensory modalities for product experience. Since product experience is multisensory, it is interesting to know which sensory modality plays a leading role in a particular experience, so that designers could concentrate on the creation of the most relevant product properties. It is often assumed that vision dominates other senses. In the present study, we investigated the importance of different sensory modalities during various episodes of product usage. We asked 120 respondents to describe their experiences with consumer products in the following situations: while buying a product, after the first week, the first month, and the first year of usage. The data suggest that the dominant modality depends on the period of product usage. At the moment of buying, vision is the most important modality, but at later stages other modalities become more important. The dominance of a particular modality may depend on its appropriateness for the particular task. During long-term usage, modality importance depends on product functions and the characteristics of the user-product interaction. We conclude that to create a long-lasting positive product experience, designers need to consider the user-product interaction at different stages of product usage and to determine which sensory modality dominates product experience at each stage.

Functions of innovation systems as a framework to understand sustainable technological change: empirical evidence for earlier claims
Understanding the emergence of innovation systems is recently put central in research analysing the process of technological change. Especially the key-activities that are important for the build up of an innovation system receive much attention. These are labeled ‘functions of innovation systems’. In most cases the authors apply this framework without questioning its validity. This paper builds on five empirical studies, related to renewable energy technologies, to test whether the functions of innovation systems framework is a valid framework to analyse processes of technological change. We test the claim that a specific set of functions is suitable. We also test whether the claim made in previous publications that the interactions between system functions accelerate innovation system emergence and growth is valid. Both claims are confirmed.
Cumulative causation in the formation of a technological innovation system: The case of biofuels in the Netherlands
Despite its worldwide success, the innovation systems approach is often criticized for being theoretically underdeveloped. This article aims to contribute to the conceptual and methodical basis of the (technological) innovation systems approach. We propose an alteration that improves the analysis of dynamics, especially with respect to emerging innovation systems. We do this by expanding on the technological innovation systems and system functions literature, and by employing the method of 'event history analysis'. By mapping events, the interactions between system functions and their development over time can be analysed. Based on this it becomes possible to identify forms of positive feedback, i.e. cumulative causation. As an illustration of the approach, we assess the biofuels innovation system in The Netherlands as it evolved from 1990 to 2005.
Understanding the build-up of a Technological Innovation System around Hydrogen and Fuel Cell Technologies
This study provides insight into the development of hydrogen and fuel cell technologies in the Netherlands (1980-2007). This is done by applying a Technological Innovation System (TIS) approach. This approach takes the perspective that a technology is shaped by a surrounding network of actors, institutions and technologies. When a technology is in an early stage of development, a TIS has yet to be built up in order to propel technological progress. This paper focuses on the historical build-up of the hydrogen and fuel cell innovation system in the Netherlands. The research focuses on processes that accelerated or slowed down the developments of hydrogen and fuel cell technologies. We suggest that this framework is helpful for actors who intend to accelerate the development and deployment of hydrogen and fuel cells in other countries.fuel cell; technological innovation system; system functions; cumulative causation.
Innovation barriers for small biotech, ICT and clean tech firms:Coping with knowledge leakage and legitimacy deficits
Innovative high-tech small and medium sized enterprises (SMEs) are thought to be drivers of economic renewal and growth. However, due to their limited size, SMEs face two fundamental innovation barriers: the risk that other organizations appropriate the returns to the newly created knowledge by SMEs (knowledge leakage), and a lack of understanding and recognition of their business on the part of potential stakeholders (legitimacy deficits). Based on a panel study of 196 SMEs this paper shows that biotech, ICT and clean tech firms choose different strategies to deal with knowledge leakage and legitimacy deficits. To prevent knowledge leakage, high-tech SMEs are very selective in choosing their R&D partners and collaborate with basic rather than applied technology developers. Furthermore, to gain organizational legitimacy, high-tech SMEs pursue activities that focus not only on product development but also on generating awareness and understanding of their technologies. �
Contemporary Innovation Policy and Instruments: Challenges and Implications
In this paper we review major theoretical (neoclassical economics, evolutionary, systemic and knowledge-based) insights about innovation and we analyse their implications for the characteristics of contemporary innovation policy and instruments. We show that the perspectives complement each other but altogether reveal the need to redefine the current general philosophy as well as the modes of operationalisation of contemporary innovation policy. We argue that systemic instruments ensuring proper organisation of innovation systems give a promise of increased rates and desired (more sustainable) direction of innovation.systemic instruments, innovation policy, innovation theory, policy mix, innovation system, sustainability
Flexible transition strategies towards future well-to-wheel chains: an evolutionary modelling approach
Well to wheel (WTW) analyses mainly focus on alternative road fuel/vehicle systems that are very different from the current crude oil based individual transport system. A large share of WTW chains evaluated require changes in the energy source, new fuel production facilities, different fuel distribution systems and also modifications of the vehicles. An immediate transition to such a new system would be an unprecedented technological discontinuity. Historical examples of successful technological changes are characterized by stepwise transitions of subsystems. In this paper, we present a model that identifies likely sequences of stepwise transitions in analogy to the fitness landscape model in evolutionary biology. Applying this methodology allows for a dynamic interpretation of otherwise static WTW information. We show that sequences of transitions are path dependent, so that current decisions predetermine the future WTW system. We, therefore, argue that flexible initial transition steps that allow for different transition paths later on are favorable. Results suggest that improvements of vehicle technologies are most flexible if decision makers focus on decreasing WTW energy requirements. A full transition to diesel, as a first step, is advisable if WTW greenhouse gases should be reduced.Alternative fuels, Hydrogen, Lock-in, Fitness-landscape
A complex systems methodology to transition management
There is a general sense of urgency that major technological transitions are required for sustainable development. Such transitions are best perceived as involving multiple transition steps along a transition path. Due to the path dependent and irreversible nature of innovation in complex technologies, an initial transition step along some preferred path may cut off paths that later may turn out to be more desirable. For these reasons, initial transition steps should allow for future flexibility, where we define flexibility as robustness regarding changing evidence and changing preferences. We propose a technology assessment methodology that identifies the flexibility of initial transition steps in complex technologies. We illustrate our methodology by an empirical application to 2646 possible future car systems.NK-model, complexity, flexibility, irreversibility, path dependence, transition path, transition management, sustainable development, car technology
Stellar molecular jets traced by maser emission
Highly collimated jets found in AGB and post-AGB stars are expected to play
an important role for shaping planetary nebulae. Recent VLBI observations of
H2O maser sources have revealed that some of the spatio-kinematical structures
of H2O maser sources exhibit stellar jets with extremely spatially and
kinematically high collimation. Such stellar H2O maser jets, so-called "water
fountain" sources, have been identified in about 10 sources to date. Here we
review recent VLBI observations and relevant observational results of the water
fountain sources. They have revealed a typical dynamical age and the detailed
kinematical structures of the water fountains, possibility of the existence of
"equatorial flows", and the evolutionary status of the host stars. The location
and kinematics of one of the water fountain sources in the Galaxy is also
revealed and shown here.Comment: 8 pages, 6 figures, in the Proceedings of the IAU Symposium 242:

Understanding the formative stage of Technological Innovation System development. The case of natural gas as an automotive fuel
This study contributes to insights into mechanisms that influence the successes and failures of emerging energy technologies. It is assumed that for an emerging technology to fruitfully develop, it should be fostered by a Technological Innovation System (TIS), which is the network of actors, institutions and technologies in which it is embedded. For an emerging technology a TIS has yet to be built up. The research focuses on the dynamics of this build-up process by mapping the development of seven key activities: so-called system functions. The main contribution revolves around the notion of cumulative causation, or the phenomenon that the build-up of a TIS may accelerate due to system functions reinforcing each other over time. As an empirical basis, an analysis is provided of the historical development of the TIS around automotive natural gas technology in the Netherlands (1970-2007). The results show that this TIS undergoes a gradual build-up in the 1970s, followed by a breakdown in the 1980s and, again, a build-up from 2000-2007. It is shown that, underlying these trends, there are different forms of cumulative causation, here called motors of innovation. The study provides strategic insights for practitioners that aspire to support such motors of innovation.functions of technological innovation systems; cumulative causation; automotive natural gas.
