Olson’s analysis argues that the free-rider problem makes large groups less effective. In this paper, we challenge this view of group action with a very simple contest game that exhibits a bilateral interplay between intergroup interaction and within-group organization. In a static setting, because of the free-riding incentives, the larger group is disadvantaged in the competition with its riva...

The Convention on Rights of Persons with Disabilities (CRPD) took effect in May 2008, and the focus of this paper is on Article 23, which requires that there be international cooperation for the promotion of the CRPD in developing countries. A main research question here is how development assistance can be utilised to promote the rights of persons with disabilities in developing countries. In ...

In social dilemma games, human participants often show conditional cooperation (CC) behavior or its variant called moody conditional cooperation (MCC), with which they basically tend to cooperate when many other peers have previously cooperated. Recent computational studies showed that CC and MCC behavioral patterns could be explained by reinforcement learning. In the present study, we use a re...

Evolvability is the capacity to evolve. This paper introduces a simple computational model of evolvability and demonstrates that, under certain conditions, evolvability can increase indefinitely, even when there is no direct selection for evolvability. The model shows that increasing evolvability implies an accelerating evolutionary pace. It is suggested that the conditions for indefinitely inc...

BACKGROUND With the exception of key 'proven successes' in global health, the current regime of global health governance can be understood as transnational and national actors pursuing their own interests under a rational actor model of international cooperation, which fails to provide sufficient justification for an obligation to assist in meeting the health needs of others. An ethical commitm...

Economic transformation has had a positive influence in Poland on statistical indices that characterize occupational safety and health (OSH). Surprisingly, working conditions have not deteriorated. Methodological differences make comparing statistical data in various countries difficult. OHS standards in Poland are harmonized with European and international ones. Testing and certification, qual...

The paper shows how an incremental generator can be constructed based on the incremental parsing framework described in Dynamic Syntax (DS)(Kempson et al., 2001), without adding a generator-specific vocabulary or intermediate levels of representation. The resulting generator is defined purely in terms of the parsing process, together with a notion of tree subsumption. This is shown to have vari...

Two-point incremental forming method is considered a modern technique for manufacturing shell parts. The presence of bottom punch during the process makes this technique far more complex than its conventional counterpart i.e. single-point incremental forming method. Thus, the numerical simulation of this method is an essential task, which leads to the reduction of trial/error costs, predicts th...
