We analyzed the effects of R&D cooperation with users and the intensity/continuity of such cooperation on firms’ innovation output—whether radical or incremental. We also examined the moderating effect of firm size on these relationships. Results show that cooperation with users favours the development of both radical and incremental product innovations. In addition, we found that the higher th...

In this paper, we investigate the benefits and drawbacks of different approaches for solving a cooperative foraging task with two robots. We compare a classical clonal approach with an additional approach which favors the evolution of heterogeneous behaviors according to two defining criteria: the evolvability of the cooperative solution and the efficiency of the coordination behaviors evolved....

In this study, we analyse incremental cooperative communication for wireless body area networks (WBANs) with different numbers of relays. Energy efficiency (EE) and the packet error rate (PER) are investigated for different schemes. We propose a new cooperative communication scheme with three-stage relaying and compare it to existing schemes. Our proposed scheme provides reliable communication ...

This paper presents an approach we have recently developed for multi robot cooperation It is based on a paradigm where robots incrementally merge their plans into a set of already coordinated plans This is done through exchange of informa tion about their current state and their future actions This leads to a generic framework which can be applied to a variety of tasks and applications The para...

The present study analyses the profile of firms cooperating with users and estimates the effect of this cooperation on firms’ innovation activities. This issue is particular novel and important as users provide information that will be very useful for generating new products and making the innovation process more efficient. The findings confirm that cooperation with users is a tool for progress...

Marshall was the great synthesiser of neoclassical economics. Yet with his qualified assumption of self-interest, his emphasis on variation in economic evolution, and his cautious attitude to the use of mathematics, Marshall differs fundamentally from other leading neoclassical contemporaries. Metaphors inspire more specific analogies and ontological assumptions, and Marshall used the guiding m...

An explosion of recent research suggests that religious beliefs and behaviors are universal, arise from deep-seated cognitive mechanisms, and were favored by natural selection over human evolutionary history. However, if a propensity towards religious beliefs is a fundamental characteristic of human brains (as both by-product theorists and adaptationists agree), and/or an important ingredient o...

iran has had incremental incidence of traffic accident mortality since introduction of mechanization about a century ago. but the newest data from iran show decrease in the absolute number of deaths, death per 10,000 vehicles and death per 100, 000 populations. despite its huge impact on health and economy, research in the field of traffic crashes is still scant and there are still deficiencies...
