The aim of the current study was twofold: (1) to validate the use of action sport cameras for quantifying focus of visual attention in sailing and (2) to apply this method to examine whether an external focus of attention is associated with better performance in upwind sailing. To test the validity of this novel quantification method, we first calculated the agreement between gaze location measures and head orientation measures in 13 sailors sailing upwind during training regattas using a head mounted eye tracker. The results confirmed that for measuring visual focus of attention in upwind sailing, the agreement for the two measures was high (intraclass correlation coefficient (ICC) = 0.97) and the 95% limits of agreement were acceptable (between -8.0% and 14.6%). In a next step, we quantified the focus of visual attention in sailing upwind as fast as possible by means of an action sport camera. We captured sailing performance, operationalised as boat speed in the direction of the wind, and environmental conditions using a GPS, compass and wind meter. Four trials, each lasting 1 min, were analysed for 15 sailors each, resulting in a total of 30 upwind speed trials on port tack and 30 upwind speed trials on starboard tack. The results revealed that in sailing - within constantly changing environments - the focus of attention is not a significant predictor for better upwind sailing performances. This implicates that neither external nor internal foci of attention was per se correlated with better performances. Rather, relatively large interindividual differences seem to indicate that different visual attention strategies can lead to similar performance outcomes.

On the internet we enjoy a continuously growing generation of web applications enabling anyone to create and publish online content in a simple way, to link content and to share it with others. The internet has become a social software platform sailing under the Web 2.0 flag, creating revolutionary changes along the way: the individual, the end-user, comes first and can benefit optimally from an environment which has the following keywords: radically user-oriented, de-centralized, collective and massive. An environment in which each participant not only listens, but can also make his own voice heard: the Social Web.

On the internet we see a continuously growing generation of web applications enabling anyone to create and publish online content in a simple way, to link content and to share it with others: wellknown instances include MySpace, Facebook, YouTube, Flickr, Wikipedia and Google Earth. The internet has become a social software platform sailing under the Web 2.0 flag, creating revolutionary changes along the way: the individual, the end-user, comes first and can benefit optimally from an environment which has the following keywords: radically user-oriented, decentralized, collective and massive. ‘An environment in which each participant not only listens, but can also make his own voice heard’: the Social Web. This document describes a brief exploration of this Social Web and intends to gain insight in possible fundamental changes this phenomenon is causing or might cause in our society. Particular attention will be paid to the impact of the Social Web on learning and education. For how do two apparently contrary developments touch and overlap? On the one side we have the rapid growth of technologies bringing individuals together to communicate, collaborate, have fun and acquire knowledge (social software). And on the other hand we have the just conviction within the world of education that young people should not only acquire knowledge and information, but should also have all kinds of skills and experience in order to meet social and technological changes deliberately, and prepare for a life long of learning.

RFID technology is a promising technology currently finding its way into the field of customer interaction strategy, supply chain accuracy and inventory management. Primarily, RFID tags are seen as substitutes of traditional barcodes, yet they can add a lot of value and functionality. Where barcodes require a scanning device to be placed directly in front of the tag to be read, RFID tag readers are able to scan all tags that are in the proximity of the scanner . The next difference is that whereas barcodes usually are the same for all articles of the of the same type (i.e. a jar of peanut butter of brand x), RFID tags will be unique for each individual product occurrence. This opens up the possibility of tracking the entire history of a specific occurrence of a product. Moreover, due to the nature of the scanning technology, it suddenly becomes achievable for manufacturers to track individual products through all stages of production and base inventory management and front office planning on real-time data at item level from production facilities.

De afgelopen jaren zijn grote stappen gezet op het gebied van dakloosheid, qua kwaliteit van de opvang en begeleiding. Tegelijkertijd is er nog steeds te weinig aandacht voor de structurele oorzaken, met voorop de bestaansonzekerheid en het tekort aan betaalbare woningen. Dit essay beschrijft de uitdagingen om te komen tot een betere aanpak. Opvallend: er is een gebrek aan eenduidigheid over wat dakloosheid is. Dat heeft gevolgen voor de politieke keuze hoeveel geld er beschikbaar is voor daklozen.

BACKGROUND: Non-use of and dissatisfaction with ankle foot orthoses (AFOs) occurs frequently. The objective of this study is to gain insight in the conversation during the intake and examination phase, from the clients’ perspective, at two levels: 1) the attention for the activities and the context in which these activities take place, and 2) the quality of the conversation. METHODOLOGY: Semi-structured interviews were performed with 12 AFO users within a two-week period following intake and examination. In these interviews, and subsequent data analysis, extra attention was paid to the needs and wishes of the user, the desired activities and the environments in which these activities take place. RESULTS AND CONCLUSION: Activities and environments were seldom inquired about or discussed during the intake and examination phase. Also, activities were not placed in the context of their specific environment. As a result, profundity lacks. Consequently, orthotists based their designs on a ‘reduced reality’ because important and valuable contextual information that might benefit prescription and design of assistive devices was missed. A model is presented for mapping user activities and user environments in a systematic way. The term ‘user practices’ is introduced to emphasise the concept of activities within a specific environment.

The promotor was Prof. Erik Jan Hultink and copromotors Dr Ellis van den Hende en Dr R. van der Lugt. The title of this dissertation is Armchair travelling the innovation journey. ‘Armchair travelling’ is an expression for travelling to another place, in the comfort of one’s own place. ‘The innovation journey’ is the metaphor Van de Ven and colleagues (1999) have used for travelling the uncharted river of innovation, the highly unpredictable and uncontrollable process of innovation. This research study began with a brief remark from an innovation project leader who sighed after a long and rough journey: ‘had I known this ahead of time…’. From wondering ‘what could he have known ahead of time?’ the immediate question arose: how do such innovation journeys develop? How do other innovation project leaders lead the innovation journey? And could I find examples of studies about these experiences from an innovation project leader’s perspective that could have helped the sighing innovation project leader to have known at least some of the challenges ahead of time? This dissertation is the result of that quest, as we do know relatively little how this process of the innovation project leader unfolds over time. The aim of this study is to increase our understanding of how innovation project leaders lead their innovation journeys over time, and to capture those experiences that could be a source for others to learn from and to be better prepared. This research project takes a process approach. Such an approach is different from a variance study. Process thinking takes into account how and why things – people, organizations, strategies, environments – change, act and evolve over time, expressed by Andrew Pettigrew (1992, p.10) as catching “reality in flight”.
