When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of informati...

Young orangutans are highly neophobic, avoid independent exploration and show a preference for social learning. Accordingly, they acquire virtually all their learned skills through exploration that is socially induced. Adult exploration rates are also low. Comparisons strongly suggest that major innovations, i.e. behaviours that have originally been brought into the population through individua...

Design space exploration is the process of analyzing several functionally equivalent alternatives to determine the most suitable one. The synchronous assumption has made it possible to develop e cient procedures for establishing functional equivalence betw een di erent implementations in the domain of synchronous circuits as well as in the domain of sync hronous reactive systems. We extend this...

Embedded systems usually have strict resource and performance constraints. Designers often need to improve the system design so that the system satisfies those constraints. In such case, performance bottlenecks should be identified and improved effectively. In this paper, we present a method to identify performance bottlenecks. Our method automatically identifies not only the bottlenecks but al...

Embodied computer vision considers perception for robots in novel, unstructured environments. Of particular importance is the embodied visual exploration problem: how might a robot equipped with camera scope out new environment? Despite progress thus far, many basic questions pertinent to this problem remain unanswered: (i) What does it mean an agent explore its environment well? (ii) Which met...

Although leadership has been studied extensively, most research has focused on the political and military spheres. More recent work has also examined the role of leadership in sectors such as manufacturing and technology, both areas where it is essential to encourage and nurture innovation. Yet, in the health sector, where innovation is now high on the policy agenda in many countries, there is ...

conclusions although evaluations of the initial vital signs and physical examinations are still important, the history regarding the source of the stab wounds (aisw vs. sisw) may be helpful in determining the appropriate treatment methods and predicting patient outcomes. results a total of 19 patients had undergone exploratory laparotomy. of the nine patients with sisw undergoing this procedure...
