Recent literature on open innovation suggests that firms can improve their performance by “opening” their business models, in other words, they can reduce their R&D costs by incorporating external knowledge. This implies that firms will be able to capture value through knowledge produced outside the organization. This, however, presents a number of difficulties notably where the knowledge produ...

Students, researchers and professional analysts lack effective tools to make personal and collective sense of problems while working in distributed teams. Central to this work is the process of sharing—and contesting—interpretations via different forms of argument. How does the “Web 2.0” paradigm challenge us to deliver useful, usable tools for online argumentation? This paper reviews the curre...

In Japanese root clauses, most verbs must be paired with the morpheme -tei to form a complex predicate in order to denote a present state. However, in certain subordinate clauses including the relative clause, the presuppositional clause of a cleft sentence, and the comparative clause, this restriction is exempted. Semantic restrictions are also imposed on verbs, and the verbs which permit the ...

Vannevar Bush's 1945 article set a goal of fast access to the contents of the world's libraries which looks like it will be achieved by 2010, sixty-five years later. Thus, its history is comparable to that of a person. Information retrieval had its schoolboy phase of research in the 1950s and early 1960s; it then struggled for adoption in the 1970s but has, in the 1980s and 1990s, reached accep...

Abstract: Since its launch in early 2005, video sharing website YouTube has emerged as a culturally, politically and economically significant medium and as one of the inheritors of the social role played by broadcast television. However its continued growth and journey to profitability is not guaranteed. This paper queries the future of YouTube by exploring the tension inherent in the site’s 3 ...

quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

This article focuses on mapping the Sun's large-scale magnetic fields. In particular, the model considers how photospheric fields evolve in time. Our solar field mapping method uses Netlogo's cellular automata software via algorithms to carry out the movement of magnetic field on the Sun via agents. This model's entities consist of two breeds: blue and red agents. The former carry a fixed amoun...

With the increase of importance of bioenergy, the whole tree harvesting system was reconsidered. As a simple way of a whole tree harvesting system, this study analyzed two winching procedures in terms of productivity and influence from terrain conditions. One of the winching procedures was observed on flat terrain, where the felled trees were scattered and then, one-by-one, attached to the winc...

RÉSUMÉ. Les hiérarchies occupent une place importante pour l’analyse dans les entrepôts de données. Mais les modèles existants ne considèrent ce concept de hiérarchie qu’au niveau des axes d’analyse que constituent les dimensions, restreignant les possibilités d’interrogation par rapport à une éventuelle hiérarchisation sur les mesures. Par exemple, dans le cadre de données médicales, une tensi...
