Combining strength and uncertainty for preferences in the graph model for conflict resolution with multiple decision makers

A hybrid preference framework is proposed for strategic conflict analysis to integrate preference strength and preference uncertainty into the paradigm of the graph model for conflict resolution (GMCR) under multiple decision makers. This structure offers decision makers a more flexible mechanism for preference expression, which can include strong or mild preference of one state or scenario over another, as well as equal preference. In addition, preference between two states can be uncertain. The result is a preference framework that is more general than existing models which consider preference strength and preference uncertainty separately. Within the hybrid preference structure, four kinds of stability are defined as solution concepts and a post-stability analysis, called status quo analysis, which can be used to track the evolution of a given conflict. Algorithms are provided for implementing the key inputs of stability analysis and status quo analysis within the extended preference structure. The new stability concepts under the hybrid preference structure can be used to model complex strategic conflicts arising in practical applications, and can provide new insights for the conflicts. The method is illustrated using the conflict over proposed bulk water exports from Lake Gisborne in Newfoundland, Canada.     

Responding to September 11: A Conflict Resolution Scholar/Practitioner's Perspective

We find ourselves thrust into a deadly conflict of potentially very large scale. This conflict may proceed in several different directions, some of which might prove quite destructive, involving high numbers of further civilian casualties on all sides. There are lessons to be drawn from both theory and practice in the field of conflict resolution that may be helpful in considering how to proceed. In this paper, we review a few important concepts from the field of conflict resolution, attempt to point out where some of these dynamics are occurring in the current situation, and highlight some potential pitfalls. Specific policy recommendations based on this analysis are offered, and the question of how we can best ensure that our response to the attacks does not lead to a degenerative cycle of violence that further destabilizes the Middle East and undermines American long-term interests is addressed.     

Domination structures and multicriteria problems in n-person games

Multiple criteria decision problems with one decision maker have been recognized and discussed in the recent literature in optimization theory, operations research and management science. The corresponding concept with n-decision makers, namely multicriteria n-person games, has not yet been extensively explored.In this paper we first demonstrate that existing solution concepts for single criterion n-person games in both normal form and characteristic function form induce domination structures (similar to those defined and studied by Yu [39] for multicriteria single decision maker problems) in various spaces, including the payoff space, the imputation space and the coalition space. This discussion provides an understanding of some underlying assumptions of the solution concepts and provides a basis for generalizing and generating new solution concepts not yet defined. Also we illustrate that domination structures may be regarded as a measure of power held by the players.We then illustrate that a multicriteria problem can naturally arise in decision situations involving (partial) conflict among n-persons. Using our discussion of solution concepts for single criterion games as a basis, various approaches for resolving both normal form and characteristic function form multicriteria n-person games are proposed. For multicriteria games in characteristic function form, we define a multicriteria core and show that there exists a single game point whose core is equal to the multicriteria core. If we reduce a multicriteria game to a single criterion game, domination structures which are more general than classical ones must be considered, otherwise some crucial information in the game may be lost. Finally, we discuss a parametrization process which, for a given multicriteria game, associates a single criterion game to each point in a parametric space. This parametrization provides a basis for the discussion of solution concepts in multicriteria n-person games.     

A taxonomy of all ordinal 2 × 2 games

The 2 × 2 game is the simplest and most commonly employed representation of strategic conflict. The 78 strict ordinal 2 × 2 games have been used as conflict models extensively, and have been related in several different taxonomies. However, interest has recently focussed on the full set of 726 general ordinal games, in which one or both players may have equal preferences for two or more outcomes. This paper describes the development of a practical taxonomy of all 726 ordinal 2 × 2 games. The taxonomy provides for rapid identification of particular games, gives a convenient ordering, is as consistent as possible with previous work, and yet is not tied to any specific solution concepts. As well, definitions of several significant game properties are developed or extended to general ordinal games and applied in conjunction with the taxonomy.     

Experiments on bilateral bargaining in markets

We present experimental data on a simple market game. Several solution concepts from cooperative game theory are applied to predict the observed payoff distributions. Notably, a recently introduced solution concept meant to capture the influence of outside options on the payoff distribution within groups fares better than most other solution concepts under consideration. Our results shed some light on the effects of scarcity relations on markets on bargaining outcomes within negotiating dyads.     

Social Conflict: Implications for Casework Practice

Summary The concept of social conflict is examined in terms of its usefulnessin refining and extending social casework theory. Attentionis given to the influence of the homeostatic approach to caseworkpractice versus an approach utilizing a conflict orientation.Primary emphasis is given to Coser's sociological theory ofconflict in an effort to discover heuristic concepts which areconsidered to be applicable in the practice of social casework.Specifically, seven of Coser's original sixteen propositionsrelated to conflict theory have been selected for analysis.It is concluded that a conflict orientation would serve to clarifythe functional aspects of conflict as they relate to the dyadiccasework relationship     

Social organizations and matching theory

We generalize the Gale-Shapley matching theory to the formation of social units consisting of more than two individuals and each individual having more than one role.We show how social preferences and social structure could conflict with freedom. In the absence of such a conflict, we define stability and show that this could conflict with social preferences and social structure. Next, we define Rawlsian justice in case of stability and show how social preferences and social structure can conflict with justice. Thus, it is the social preferences and social-structure which decide whether our concepts of freedom, stability, and justice are achievable or not.     

On the evaluation of solution concepts

It is proposed that solution concepts for games should be evaluated in a way that is analogous to the way a logic is evaluated by a model theory for the language. A solution concept defines a set of strategy profiles, as a logic defines a set of theorems. A model theoretic analysis for a game defines a class of models, which are abstract representations of particular plays of the game. Given an appropriate definition of a model, one can show that various solution concepts are characterized by intuitively natural classes of models in the same sense that the set of theorems of a logic is characterized by a class of models of the language. Sketches of characterization results of this kind are given for rationalizability, Nash equilibrium, and for a refinement of rationalizability —strong rationalizability — that has some features of an equilibrium concept. It is shown that strong rationalizability is equivalent to Nash equilibrium in perfect information games. Extensions of the model theoretic framework that represent belief revision and that permit the characterization of other solution concepts are explored informally.     

On games under expected utility with rank dependent probabilities

Expected utility with rank dependent probabilities is a generalization of expected utility. If such preference representations are used for the payoffs in the mixed extension of a finite game, Nash equilibrium may fail to exist. Set-valued solutions, however, do exist even for those more general utility functions. But some set-valued solutions may have certain conceptual shortcomings. The paper thus proposes a new set-valued solution concept, called fixed sets under the best reply correspondence. All set-valued solution concepts are robust to perturbations of the expected utility hypothesis.

An Empirical Comparison of Probabilistic Coalition Structure Theories in 3-Person Sidepayment Games

This article reports a comparative test of the central-union theory vis-à-vis several other game-theoretic solution concepts in 3-person sidepayment games. Based on a laboratory experiment, this comparison utilizes nine games in characteristic function form. The solution concepts under test include the equal excess model, the Myerson–Shapley solution, the kernel, and two variants of the central-union theory (CU-1 and CU-2). With regard to the player's payoffs, results show that the CU-1, CU-2, kernel, and equal excess theories have essentially equal predictive accuracy and that all of these are more accurate than Myerson–Shapley. When the solution concepts are extended and coalition structure probability predictions are incorporated in the test, one version of the central-union theory (CU-2) is overall more accurate than the other solutions.     

Mainland Chinese Adolescents' Judgments and Reasoning about Self-determination and Nurturance Rights

Younger (13 years) and older (17 years) adolescents (N  =  160) from urban and rural China responded to written scenarios in which children's rights to self-determination and nurturance conflicted with the desires of authorities. They also evaluated scenarios in which children's desire to exercise self-determination was in conflict with their own welfare interests (nurturance). Older participants and those from urban settings were more likely than younger participants and those from rural settings to endorse self-determination, both when in conflict with authority and nurturance. When supporting self-determination, participants appealed to individual rights, autonomy, and personal choice in their justifications. The findings indicate that concepts of diverse types of rights are maintained by adolescents from both modern and traditional settings in China.     

Dialogical Demand: Discursive Position Repertoires for a Local and Global UK Sex Industry

The increasing incidence of ‘trafficking’ has added an incontestably disturbing dimension to the contestable nature of a ‘non‐trafficked’ UK sex industry. Men who buy sex remain under‐researched, though some studies have indicated ambivalence within men's attitudes. This study combines a critical discursive psychology in support of dialogical self theory. Secondary data, from prominent UK media resources, were analysed using Edley's (2001) method of combining ‘interpretative repertoires’, ‘ideological dilemmas’ and ‘subject positions’. Contrasting discursive practices indicative of wider ideological conflict were found. Discursive concepts were ‘mapped’ onto Hermans and Hermans‐Konopka's (2010) ‘I‐positions’ to explore how these potentially dilemmatic positions might be understood in terms of identity production. The function of ‘uncertainty’, particularly salient with the increasing complexity of globalisation, was considered a factor in how men's identities might be limited by the current discursive space. A ‘dialogical’ model of self is introduced as a framework for understanding how men who buy sex might take up new, inclusive, positions. A corollary is reflected upon; that researchers, activists and buyers alike, who remain ideologically inflexible, may be sustaining the conditions for coercion through their contribution to the discursive conflict. The synthesis of discursive and dialogical analytical tools is recommended for investigating the production of selves in contested spaces.     

Dynamics of Young Children's Socially Adaptive Resolutions of Peer Conflict

How do young children negotiate conflicts with peers that result in mutually beneficial resolution and peaceful interaction after conflict? A few studies suggest that when children use conciliatory strategies in conflict, socially adaptive outcomes are more likely to be achieved. The present study explores the relative associations of types of children's conciliatory conflict resolution strategies (i.e., prosocial, compliance‐oriented, solution‐oriented, and verbal clarification/apology) with conflict outcomes to contribute to knowledge of the discrete behaviors that might have salience for conflict resolution training. Socially adaptive conflict outcomes were expected to strongly relate to children's resolution strategies of a prosocial nature as well as to teacher or peer interventions encouraging prosocial behavior or empathy. Sampled conflicts (N = 521) were collected through field observations of 107 ethnically/racially and socioeconomically diverse four‐ to seven‐year‐old children. Logistic regression analyses with bootstrap‐based inference suggested that children's prosocial behaviors in conflict were most strongly tied to mutually beneficial resolution and peaceful postconflict interaction, when controlling for relevant covariates. Other conciliatory strategies varied in their association with socially adaptive outcomes. The hypothesis regarding third‐party interventions encouraging prosociability or empathy could not be examined due to infrequent occurrence. Insights for future research on children's socially adaptive conflict negotiations are discussed.     

The Interdependence of Israeli and Palestinian National Identities: The Role of the Other in Existential Conflicts

The interactions between identity groups engaged in a protracted conflict lack the conditions postulated by Gordon Allport in The Nature of Prejudice (1954) as necessary if contact is to reduce intergroup prejudice. The article examines the Israeli-Palestinian conflict from this perspective. After summarizing the history of the conflict, it proposes that a long-term resolution of the conflict requires development of a transcendent identity for the two peoples that does not threaten the particularistic identity of each. The nature of the conflict, however, impedes the development of a transcendent identity by creating a state of negative interdependence between the two identities such that asserting one group's identity requires negating the identity of the other. The resulting threat to each group's identity is further exacerbated by the fact that each side perceives the other as a source of some of its own negative identity elements, especially a view of the self as victim and as victimizer. The article concludes with a discussion of ways of over-coming the negative interdependence of the two identities by drawing on some of the positive elements in the relationship, most notably the positive interdependence between the two groups that exists in reality. Problem-solving workshops represent one setting for equal-status interactions that provide the parties the opportunity to "negotiate" their identities and to find ways of accommodating the identity of the other in their own identity.     

Using Student Task Groups to Teach Group Process and Development

This article discusses an experiential assignment used in a group work course. Student groups meet throughout the semester with the task of developing a major group presentation. The assignment has the dual purpose of increasing student knowledge of diverse group approaches and providing opportunities to experience, identify, and apply group work concepts to their small-group experiences. The article uses excerpts from students' discussions about their group experiences to demonstrate the effectiveness of the assignment. Three primary themes are explored: (1) group development and emerging norms and roles, (2) issues of leadership, and (3) the role of conflict in the groups.

Improving the approach to conflict in action research through deliberative policy analysis: a territorial development case in the Basque Country

ABSTRACT

This paper focuses on how theoretical work developed in deliberative policy analysis (DPA) can contribute to action research (AR) through a better understanding of the policy world. It is based on a programme in Gipuzkoa, Basque Country (Spain) where action researchers have been collaborating with policymakers since 2009. Our paper shows how concepts like pluralism, agonism and escalation have helped to reframe the approach to conflict in action research for territorial development (ARTD). The aim of the case is not exclusively to demonstrate how this can be done at a micro level, but also to show the usefulness of further interaction between the fields of DPA and AR, based on this experience.     

工作-家庭冲突、性别角色与工作满意度——基于第三期中国妇女社会地位调查的实证研究

本文使用2010年第三期中国妇女社会地位调查数据,研究了工作-家庭冲突对工作满意度的影响及其性别差异,发现来自工作和家庭两方面的角色压力是引发工作-家庭冲突的主要原因,而且无论是因工作影响家庭,还是因为家庭耽误工作,员工都会对工作表达不满。与男性员工相比,工作压力和家庭压力会使女性员工陷入更为严重的工作-家庭冲突,而且女性员工也更可能因为工作影响家庭而降低对工作的满意度。这些发现不仅为工作-家庭冲突及其相关后果的理论研究提供了丰富的经验证据,还为各级管理人员激励员工士气和提高组织绩效提供了很多实践上的启示。
