The need to manage water resource within a holistic approach is crucial in Indonesia. Conflict situation which involves a variety of stakeholder needs an appropriate methodology to handle it. The purpose of this paper is to provide an integrated framework of a river basin pollution case in Indonesia. This research try to obtain an understanding of the complexity of inter-relationship between stakeholders of the Citarum River Basin and to give feasible recommendations based on a new developed integrated framework. We first describe the problem in a comprehensive way, then develop a framework to analyze the conflict. Next, we propose a general procedure to apply it, which we call Drama-theoretic Dilemma Analysis (DtDA). After analyzing the conflicts that arise there between stakeholders using DtDA, we will show how to resolve the dilemmas by using holistic as well as intensive approaches. By applying DtDA in stakeholder analysis and resolving the dilemmas that arise in the interactions between them, we can identify barriers for collaboration. 相似文献

This paper discusses the relationship of two independently developed models of games with incomplete information, hierarchical hypergames and Bayesian games. It can be considered as a generalization of the previous study on the theoretical comparison of simple hypergames and Bayesian games (Sasaki and Kijima, 2012) by taking into account hierarchy of perceptions, i.e., an agent’s perception about the other agents’ perceptions, and so on. The authors first introduce the general way of transformation of any hierarchical hypergames into corresponding Bayesian games, which was called as the Bayesian representation of hierarchical hypergames. The authors then show that some equilibrium concepts for hierarchical hypergames can be associated with those for Bayesian games and discuss implications of the results. 相似文献

1 Results Low-temperature synthetic techniques called “chimie douce“ have resulted in major developments in the field of solid state chemistry of transition metal oxides. The systematic study of oxide bronzes in the period 1950-1980 paved the way to further advances in the solid state chemistry of oxides, including the alkali metal intercalation(deintercalation chemistry by soft chemical and/or electrochemical methods. These techniques also gave access to new metastable compounds such as several new f... 相似文献

The present study discusses the relationships between two independently developed models of games with incomplete information,hypergames(Bennett,1977) and Bayesian games(Harsanyi, 1967).The authors first show that any hypergame can naturally be reformulated in terms of Bayesian games in an unified way.The transformation procedure is called Bayesian representation of hypergame. The authors then prove that some equilibrium concepts defined for hypergames are in a sense equivalent to those for Bayesian games.Furthermore,the authors discuss carefully based on the proposed analysis how each model should be used according to the analyzer’s purpose. 相似文献

This paper aims to propose ERT (Expected Reaching Time), a new risk adverse evaluation criterion of finite multiplication processes, and to examine its properties in relation to the dominance criterion. The ERT means the expected time that takes for an objective valiable to reach a target value. To deal with the environmental risk involved in the process, the expectation maximizing strategy may be the most well known. However, for many cases the dominance strategy rather than the expectation maximizing strategy is adopted and works very well. In this paper we first prove rigorously that minimization of the ERT is equivalent to the dominance criterion in the infinite period. Then we demonstrate by simulation that the ERT gives almost equal evaluation as the dominance criterion even for the finite multiplications, after showing that it is approximately proportional to the logarithm of the target value. 相似文献

A number of solution concepts of normal-form games have been proposed in the literature on subspaces of action profiles that
have Nash type stability. While the literature mainly focuses on the minimal of such stable subspaces, this paper argues that
non-minimal stable subspaces represent well the multi-agent situations to which neither Nash equilibrium nor rationalizability
may be applied with satisfaction. As a theoretical support, the authors prove the optimal substructure of stable subspaces
regarding the restriction of a game. It is further argued that the optimal substructure characterizes hierarchical diversity
of coordination and interim phases in learning. 相似文献

1 IntroductionThe purpose of this Paper is to generalize Landscape theory[1] proposed by R.AXeirod and,then, to apply it to the civil aviation industry for simulating ajliance formation in it.Landscape theory provides a well-known agent-based simulation model for analyzing andpredicting alliance (or coalition) formation process. The theory makes two basic assumptions.The first assumption is that an agent is myopic in its assessments. In Other words, an agenteclates how well it gets along wi… 相似文献

The liver and exocrine pancreas share a common structure, with functioning units (hepatic plates and pancreatic acini) connected to the ductal tree. Here we show that Sox9 is expressed throughout the biliary and pancreatic ductal epithelia, which are connected to the intestinal stem-cell zone. Cre-based lineage tracing showed that adult intestinal cells, hepatocytes and pancreatic acinar cells are supplied physiologically from Sox9-expressing progenitors. Combination of lineage analysis and hepatic injury experiments showed involvement of Sox9-positive precursors in liver regeneration. Embryonic pancreatic Sox9-expressing cells differentiate into all types of mature cells, but their capacity for endocrine differentiation diminishes shortly after birth, when endocrine cells detach from the epithelial lining of the ducts and form the islets of Langerhans. We observed a developmental switch in the hepatic progenitor cell type from Sox9-negative to Sox9-positive progenitors as the biliary tree develops. These results suggest interdependence between the structure and homeostasis of endodermal organs, with Sox9 expression being linked to progenitor status. 相似文献
