Sometimes we punish non-cooperators in our society. Such behavior could be derived from aversive emotion for inequity (inequity aversion) to make non-cooperators cooperative. Thus, punishing behavior derived from inequity is believed to be important for maintaining our society. Meanwhile, our daily experiences suggest that the degree of cooperation by the members of society (cooperation level o...

The European Society for Blood and Marrow Transplantation was established in 1974 to enable scientists and physicians involved in clinical bone marrow transplantation to share their experience and develop cooperative studies. The organization celebrated its 40th anniversary with a meeting that considered hematopoietic stem cell transplantation not as a standalone procedure, but as part of a com...

Modelling a society of cooperative and autonomous mobile robots can be viewed as a multi-agent issue, i.e., the task to determine a multi-agent architecture for a robot society according to this two requirements. In this paper, we motivate a multi-layered approach to fulfill cooperation and autonomy. We propose an agent model together with an interaction model based on this approach. Features o...

We analyze the structure of a society driven by power relations. Our model has an exogenous power relation over the set of coalitions of agents. Agents determine the social order by forming coalitions. The power relations determine the ranking of agents in society for any social order. We study a cooperative game in partition function form and introduce a solution concept, the stable social ord...

Cooperative Co-evolutionary Algorithms: A Society Model Qiangfu Zhao The University of Aizu, Japan 965-80 E-mail: [email protected] Abstract| Compared with the conventional algorithms, the evolutionary algorithms (EAs) are usually more e cient for system design because they can provide higher opportunity for obtaining the global optimal solution. However, the EAs cannot be used directly to d...

The cost of living is high in Juba, the capital of the world’s youngest nation, the Republic of South Sudan.1 Decades of conflict have wiped out basic infrastructure and destroyed what production capacity it once had. So most goods—including food, basic inputs and construction materials—must be imported. That can be costly and slow. An entrepreneur in Juba would have to spend $9,429 to import a...

1 The issue The purpose of this essay is to shed some light on a certain type of sentence, which I call a borderline contradiction. A borderline contradiction is a sentence of the form F a ∧ ¬F a, for some vague predicate F and some borderline case a of F , or a sentence equivalent to such a sentence. For example, if Jackie is a borderline case of 'rich', then 'Jackie is rich and Jackie isn't r...

Exchanging ideas with like-minded, enthusiastic people interested in the same topic is crucial for the advancement of a scientist's career. Several Regional Student Groups (RSGs) of the International Society for Computational Biology (ISCB) Student Council have cooperated in the last six years to organize scientific workshops and conferences. With motivated students, it is possible to create a ...
