Some of them operate fast but generate results in contradiction to human perception. Others yield better results, especially the Earth Mover's Distance (EMD) (Rubner et al., Int J Comput Vis, 40(2):99-121, 2000), but its computational complexity prevents its usage in large databases (Ling et al., IEEE Trans Pattern Anal Mach Intell, 29(5):840-853, 2007). This paper presents a new intuitive intelligible approximation of EMD. The empirical study tries to answer the question whether the good results of EMD justify its long computation time.

Their functions, contributions and interactions within companies have been subject to numerous investigations. From a theoretical point of view, promotor theory focuses on several specialists to overcome different barriers to innovation, while champion theory concentrates on generalists playing multiple roles. Empirical results point to generalists being better suited for highly innovative projects, but on the other hand different roles should preferably be played by different key persons. A central gap in the literature is that this issue has not been investigated sufficiently so far in an inter-organizational context. The questions are: Is role accumulation beneficial for innovation project performance with respect to the key persons? Is role accumulation even more advantageous with increasing degrees of innovativeness? A sample of 107 innovation projects where small and medium-sized enterprises take part is used as a unit of analysis. The network manager served as the respondent. A measurement approach based on an extended Rasch scale was introduced for this purpose. The results show that indeed 'too many cooks spoil the broth': Instead of many single-role players in each organization, we need a few multiple role players in an inter-organizational context.}, language = {en} } @inproceedings{ReseKutschkeBaier, author = {Rese, Alexandra and Kutschke, Anke and Baier, Daniel}, title = {Analyzing the Relative Influence of Available Supply Factors on the Successful Development of New Energy Technologies}, series = {Proceedings of the 20th International Product Development Management Conference}, booktitle = {Proceedings of the 20th International Product Development Management Conference}, publisher = {EIASM}, address = {Brussels}, abstract = {Die Paper werden begutachtet: The goal of the review process is to select a number of papers that will stimulate discussion and the development of new knowledge, with preference given to empirical research.

Besides the limitations and critics that accompanied with stated importance techniques, a lot of research results show that it is better to use direct methods in place of indirect measures.

This is true not only for new users of goods or services, but also for their producers. They extend the insight into the acceptance of new goods and services, e.g. at the point of sale, from a mere sales and usage quantity oriented point of view to a cause and effect oriented one. Since online reviews by consumers of many goods and services are nowadays widespread and easily available on the internet, the question arises whether their analysis can replace the more traditional approaches to measure technology acceptance, e.g., using questionnaires with TAM (Technology Acceptance Model) items. This paper tries to answer this question using IKEA's mobile catalogue app as an example. For comparisons reasons, data on the acceptance of the current version of this catalogue is collected in four different ways, (1) as answers to batteries of TAM items, (2) as assignments to pre-defined adjective pairs, (3) as textual likes and dislikes of users (simulating online reviews), and (4) as publicly available (real) reviews by users. The source for (1)-(3) is a survey with a sample of respondents, the source for (4) an online forum. The data is analyzed using partial least squares (PLS) for TAM modelling and text mining for pre-processing the textual data. The results are promising: it seems that data collection via surveys can be replaced - with some reservations - by the analysis of publicly available (real) online reviews.}, language = {en} } @misc{SelkaBaier, author = {Selka, Sebastian and Baier, Daniel}, title = {Kommerzielle Anwendung auswahlbasierter Verfahren der Conjointanalyse: Eine empirische Untersuchung zur Validit{\"a}tsentwicklung}, series = {Marketing Zeitschrift f{\"u}r Forschung und Praxis}, volume = {36}, journal = {Marketing Zeitschrift f{\"u}r Forschung und Praxis}, number = {1}, issn = {0344-1369}, pages = {54 -- 64}, language = {de} }
