Roadmapping, originated from industry as a strategic planning tool, is attracting increasing applications in academy. Based on the recognition that roadmapping is a knowledge creation process, this paper analyzes what kind of support is needed or helpful for establishing a creative environment for roadmapping in academy and reviews various types of such support from the perspective of i-system methodology. As case studies of such support, this paper further introduces roadmapping pratices in Janpan Advanced Institute of Science and Technology.

The dynamic effects of smoke are impressive in illustration design,but it is a troublesome and challenging issue for inexpert users to design smoke effects without domain knowledge of fuid *** this work,we propose DualSmoke,a two-stage globalto-local generation framework for interactive smoke illustration *** the global stage,the proposed approach utilizes fluid patterns to generate Lagrangian coherent structures from the user's hand-drawn *** the local stage,detailed flow patterns are obtained from the generated coherent ***,we apply a guiding force field to the smoke simulator to produce the desired smoke *** construct the training dataset,DualSmoke generates flow patterns using finite-time Lyapunov exponents of the velocity *** synthetic sketch data are generated from the fow patterns by skeleton *** user study verifies that the proposed design interface can provide various smoke illustration designs with good user *** code is available at https://***/shasph/DualSmoke.

The relationship between tacit knowledge and informal networks has not been fully explored. Tacit knowledge cannot be well managed directly, because it is deeply embedded in individual actions and experiences. This study proposes an approach to managing informal networks as a new middle way to facilitate the sharing and transferring of tacit knowledge, owing to the fact that tacit knowledge is mostly shared and transferred through informal networks. To support the idea of the approach, an empirical case study of applying the approach to management of a large scientific project is also included. Our findings suggest that informal networks play essential roles for management of tacit knowledge, and thus good management of informal networks can lead to efficient sharing and transferring of tacit knowledge.

The purpose of this paper is to generalize Landscape theory proposed by R. Axelrod and, then, to apply it to the civil aviation industry for simulating alliance formations in it. Landscape theory provides a well-known agent-based simulation model for analyzing alliance (or coalition) formation process. When a set N of agents or autonomous decision makers is given, the theory assumes that each agent tries to make a coalition in such a way that the resulting alliance minimizes its frustration. The theory is essentially based on two premises. One is that a propensity is symmetric, i.e., the propensity of agent i toward j is exactly the same as that of j toward i for any agents i and j in N. The other is that the number of alliances is restricted to two, i.e., at any moment N is partitioned into two parties. Though the two basic premises underpin the theory and make the model simple and operational, they do not always reflect alliance formation processes in a realistic way. A generalized Landscape theory that this paper proposes removes them and allows asymmetric propensity and existence of alliances of any number. Since the premises are essential for the model, the generalization requires a drastic reconstruction of the whole idea of the theory. Finally, we analyze a real alliance formation process in the civil aviation industry. This analysis provides interesting insights about the industry as well as some validation of our generalized Landscape theory.

Graduate students who are beginning academic research want to learn how to create and verify new knowledge in their research. Their supervisors, on the other hand, are seeking appropriate research environments including effective research guidance methods. In order to meet these demands, this paper proposes a knowledge creation model that supports the objectives of both graduate students and their supervisors. This is an academic knowledge creation model for individuals supported by a group and its origin can be traced back to a famous organizational knowledge creation model. Since this type of model is constructed from empirical knowledge, it is not easy to prove its objective significance. But, this paper tries to show the effectiveness of the proposed model as an initial stage of model validation based on a questionnaire survey of students in a graduate school in China.
