Reinforcement learning has recently received much attention as a learning method for complicated systems, e.g., robot systems. It does not need prior knowledge and has higher capability of reactive and adaptive behaviors. However increase in dimensionality of the action-state space makes it diffcult to accomplish learning. The applicability of the existing reinforcement learning algorithms are effective for simple tasks with relatively small action-state space. In this paper, we propose a new reinforcement learning algorithm: “Q-learning with Dynamic Structuring of Exploration Space (...) Based on Genetic Algorithm ”. The algorithm is applicable to systems with high dimensional action and interior state spaces, for example a robot with many redundant degrees of freedom. To demonstrate the effectiveness of the proposed algorithm simulations of obstacle avoidance by a 50 links manipulator have been carried out. It is shown that effective behavior can be learned by using the proposed algorithm. (shrink)

Reinforcement learning is very effective for robot learning. Because it does not need priori knowledge and has higher capability of reactive and adaptive behaviors. In our previous works, we proposed new reinforcement learning algorithm: “Q-learning with Dynamic Structuring of Exploration Space Based on Genetic Algorithm (QDSEGA)”. It is designed for complicated systems with large action-state space like a robot with many redundant degrees of freedom. And we applied it to 50 link manipulator and effective behavior is acquired. However optimality and (...) fault tolerance of the proposed algorithm were not considered and to demonstrate effectiveness of the proposed algorithm other applications are necessary. Acquiring of locomotion patterns by a multi-legged robot is a very interesting problem. As it has many redundant degrees of freedom, application of usual reinforcement learning is difficult and an optimal locomotion has not been acquired using previous reinforcement learning algorithm. And the redundancy of the robot is effective to the fault tolerance and various locomotion patterns can be acquired for adapting the faults of the legs. In this paper, we applied QDSEGA to acquiring of locomotion pattern by the multi-legged robot and considered the optimality and fault tolerance. Effective behavior has been obtained by using our proposed algorithm. (shrink)

This paper examines how Japanese multinational companies manage corporate social responsibility (CSR). It considers how the concept has come to be framed within Japanese business, which is increasingly globalized and internationally focused, yet continues to exhibit strong cultural specificities. The discussion is based on interviews with managers who deal with CSR issues and strategy on a day-to-day basis from 13 multinational companies. In looking at how CSR practice has been adopted and adapted by Japanese corporations, we can begin to see (...) what implications arise from the fact that CSR is a Western-led concept, so opening up critical questions about the future development and evolution of CSR practice within a global context. In being exposed to the concept of CSR as practiced vigilantly in western countries, Japanese multinational company managers have certainly come to re-evaluate aspects of business likely to need rectifying (with potential concerns being gender inequalities, discrepancies in employee conditions, and issues over human rights and supply chains). Japan can be thought to be lagging behind in its understanding and adoption of CSR, in part because corporations do not necessarily state their policies as formally as might be expected. Yet, by analyzing more deeply the kinds of responses gained from CSR managers in Japan (and by placing their remarks within a broader context of Japanese culture and business practices) a far more subtle and revealing picture becomes apparent, not least a more complex picture of the local/global interaction of the frames of reference of corporate responsibility.
