In 1951 Professor weimin Zheng returned to the People＇s Republic of China from the United Kingdom to assist in building his country into a modern nation. Rather than pursue a doctoral degree at the California Institute of Technology, or Caltech as it is popularly called, Professor Zheng, unselfishly and patriotically, decided that he would devote his many talents to providing a first-class education to Chinese students within a strong university system. In particular,

The strategic decisions and resulting consequences surrounding the conflict between the United States of America (US) and Iran regarding the Iranian nuclear program are formally investigated using a flexible decision methodology called the Graph Model for Conflict Resolution (GMCR). This highly controversial dispute caught the world's attention as concerns were growing that Iran would reach a position where it would be able to build nuclear weapons, thereby posing a risk to world security. while Iran insisted on its rights for the peaceful use of nuclear technology;the international community;led by the US, tried to discourage the nuclear activities of Iran to ensure its obligations to the non-proliferation of nuclear weapons. This led to an escalation of tension on both sides, with an extension of the nuclear program by Iran and an increase in sanctions by the US, before it was possible to arrive at a negotiated agreement. As demonstrated in this paper, a systematic GMCR investigation provides valuable strategic insights into this important conflict. Further, it illustrates ways in which the conflict could have evolved, as well as mechanisms for stopping an escalation like this in the future.

Insightful theorems are established on interrelationships among coalition and noncooperative stability concepts defined within the paradigm of the Graph Model for Conflict Resolution. More specifically, the newly defined coalition stability def＇mitions that are considered are coalition Nash stability （CNash）, coalition general metarationality （CGMR）, coalition symmetric metarationality （CSMR） and coalition sequential stability （CSEQ）, along with their earlier-defined noncooperative versions. A range of interesting new theorems are derived to establish connections among these coalition stability concepts as well as between noncooperative and coalition stability definitions. Applications with respect to the games of Prisoner＇s Dilemma and Chicken, as well as a groundwater contamination dispute, demonstrate how the various stability definitions can be applied in practice and confirm the validity of some of the theorems as well as point out, by example, certain types of relationships which cannot hold.

Formal systems engineering approaches to modeling misperceptions and attitudes are employed within the framework of the graph model for conflict resolution to systematically study the war of 1812 between the United States of America and Great Britain in order to provide enhanced insights into the causes of the war. More specifically, relational definitions for preferences, movements and stability concepts are defined for describing the attitudes and associated behavior of decision makers involved in a conflict. To capture misperceptions of decision makers in the war of 1812, attitudes are studied within the structure of a hypergame. Combining attitudes and misperceptions within the paradigm of the graph model furnishes the flexible analytical tool which demonstrates that misunderstanding of attitudes by Great Britain and the United States may have contributed to the outbreak of this nasty war.

A formal policy development framework, based on a system of systems （SOS） approach, is synthesized to systematically address, in an integrative and adaptive fashion, major global challenges, such as the current food and fjnancial crises, and their interactions with other key natural, societal, and technological systems. A SoS approach seeks to respect the different value systems of multiple participants, to harness complexity through effective integration, and to engage the world of uncertainty and unpredictability with an adaptive response. Faced with the present global challenges, what is needed are strategic and operational methods which lead to ethical policies, enhance integrative and adaptive management practices, and are able to direct conflict resolution in a positive direction. Policy makers need tools to model and analyze complex systems which they are trying to responsibly govern, taking into account values and risks to design and evaluate different policies. A preliminary investigation into the global food system is undertaken to understand the SoS and to provide insights on how to carry out policy development using the proposed framework.

New solution concepts for n-decision maker conflicts based on generalized metarationalities for modelling possible human behaviour under conflict are proposed.A classification of these solution concepts,also called stability definitions,is presented both to simplify understanding and to illustrate important differences among different stability *** relationships among solution concepts are explored and new,more specific results are obtained in the comparison among existing stability concepts and the newly proposed *** informative example is used to demonstrate the applicability and insights of these solution concepts.

A formal methodology for analyzing the importance of weighing a decision maker＇s attitudes in a conflict is introduced and applied to the problem of negotiating a fair transfer of a brownfield property. A decision maker＇s attitudes are expressed in his consideration of his own preferences, as well as those of his opponents. Dominating attitudes are used to suggest that in a circumstance in which a decision maker takes into account multiple perspectives due to his attitudes, he may favor one perspective more heavily. The analysis of a brownfield acquisition conflict illustrates the types of insights that this methodology reveals.

The nitrogen (N) cycle is essentially 'leaky'. The losses of small amounts of nitrate to waters and of ammonia and nitrous oxide to the atmosphere are a part of the global biogeo-chemical N cycle. However, intensive agricultural production, industry and vehicle use have more than doubled the amount of 'reactive' N in the environment, resulting in eutrophication, ecosystem change and health concerns. Research has identified agricultural practices that cause large losses of N and, in some cases, developed solutions. This paper discusses the problems of maintaining productivity while reducing N losses, compares conventional with low input (integrated) and organic farming systems, and discusses wider options. It also looks at the need to integrate studies on N with other environmental impacts, set in the context of the whole farm system, to provide truly sustainable agricultural systems.

The key objective of this special issue of the Journal of Systems Science and Systems Engineering (JSSSE) is to assess papers con? taining leading-edge ideas on the theory and practice of conflict resolution and group decision making. Earlier versions of these fine papers were originally delivered by the authors at the 18th International Conference on Group Decision and Negotiation (GDN) which was held in Nanjing, China, from June 9 to 13,2018 (GDN 2018), and which appeared as extended abstracts in a conference proceedings ed让ed by Jiang et al.
