Decision support in interest based negotiation support systems: the AssetDivider system

Negotiation Support Systems (NSS) model the process of negotiation from basic template support to more sophisticated decision making support. The authors attempt to develop systems capable of decision support by suggesting possible solutions for the given dispute. Current Negotiation Support Systems primarily rely upon mathematical optimisation techniques and often ignore heuristics and other methods derived from practice. This chapter discusses the technology of several negotiation support systems in family law developed in their laboratory based on data collected and methods derived from practise. The chapter explores similarities and differences between systems the authors have created and demonstrates their latest development, AssetDivider.

Managing negotiation knowledge with the goal of developing negotiation decision support systems

While Information Technology has been used to support negotiation there is little research in the domain of knowledge management in legal negotiation. In this paper we discuss the nature of negotiation knowledge and how such knowledge can be utilized to construct negotiation decision support systems. We conduct an in-depth examination of the notion of a BATNA (Best Alternative to a Negotiated Agreement) and given a useful BATNA, how we can use issue and preference elicitation and compensation and trade-off strategies to provide negotiation decision support. We conclude by indicating how current negotiation support systems can be extended to support Online Dispute Resolution and haw we can extend the Family_Winner system in light of the need to more adequately manage negotiation knowledge.

Bargaining in the shadow of the Law - using utility functions to support legal negotiation

Most dispute resolution is settled by negotiation rather than litigation. However, such bargaining often occurs in the shadow of the law. To help support interest-based negotiation, we explore the use of utility functions to support negotiation analysis. We discuss in detail a utility function we have developed in the area of family-law mediation. This function is currently being used as the basis of an online dispute resolution system.

Incorporating fairness into development of an integrated multi-agent online dispute resolution environment

The paper describes the development of an integrated multi-agent online dispute resolution environment called IMODRE that was designed to assist parties involved in Australian family law disputes achieve legally fairer negotiated outcomes. The system extends our previous work in developing negotiation support systems Family_Winner and AssetDivider. In this environment one agent uses a Bayesian Belief Network expertly modeled with knowledge of the Australian Family Law domain to advise disputants of their Best Alternatives to Negotiated Agreements. Another agent incorporates the percentage split of marital property into an integrative bargaining process and applies heuristics and game theory to equitably distribute marital property assets and facilitate further trade-offs. We use this system to add greater fairness to Family property law negotiations.

Developing negotiation decision support systems that support mediators : a case study of the Family_Winner system

Negotiation Support Systems have traditionally modelled the process of negotiation. They often rely on mathematical optimisation techniques and ignore heuristics and other methods derived from practice. Our goal is to develop systems capable of decision support to help resolve a given dispute. A system we have constructed, Family_Winner, uses empirical evidence to dynamically modify initial preferences throughout the negotiation process. It sequentially allocates issues using trade-offs and compensation opportunities inherent in the dispute.

How information technology can support family law and mediation

In Australia, before a divorcing couple can have their case heard by the Family Court, they must undertake mediation. Thus it is useful to develop information technology tools to support negotiation and mediation in family law. Most negotiation support systems focus upon integrative bargaining. In doing so, they tend to ignore issues of fairness. In Australian Family Law, the interests of the children, as opposed to those of their parents/guardians, are paramount. We investigate the use of providing BATNAs and integrative bargaining in providing family mediation decision support. The discussion is highlighted with examples taken from the domain of Australian Family Law

A visual language and environment for enterprise system modelling and automation

Objective: We want to support enterprise service modelling and generation using a more end user-friendly metaphor than current approaches, which fail to scale to large organisations with key issues of "cobweb" and "labyrinth" problems and large numbers of hidden dependencies. Method: We present and evaluate an integrated visual approach for business process modelling using a novel tree-based overlay structure that effectively mitigate complexity problems. A tree-overlay based visual notation (EML) and its integrated support environment (MaramaEML) supplement and integrate with existing solutions. Complex business architectures are represented as service trees and business processes are modelled as process overlay sequences on the service trees. Results: MaramaEML integrates EML and BPMN to provide complementary, high-level business service modelling and supports automatic BPEL code generation from the graphical representations to realise web services implementing the specified processes. It facilitates generated service validation using an integrated LTSA checker and provides a distortion-based fisheye and zooming function to enhance complex diagram navigation. Evaluations of EML show its effectiveness. Conclusions: We have successfully developed and evaluated a novel tree-based metaphor for business process modelling and enterprise service generation. Practice implications: a more user-friendly modelling approach and support tool for business end users.

AssetDivider : a new mediation tool in Australian family law

This article describes research in a new theory of decision support in negotiation in family law mediation. AssetDivider was based on the principles of Family_Winner. As a Negotiation Decision Support System Family_Winner takes ratings assigned to items by the parties involved and develops a list of allocations to each party; based on trade-offs inherently present in the dispute. Given advice provided from our industry partners Relationships Australia (Queensland) - RAQ, AssetDivider uses an ideal “percentage split” to guide the development of an allocation list for parties. The system has been tested informally by our contacts at RAQ, and we now look forward to extensive testing and evaluation by mediators at RAQ in the near future. We hope to report on a comprehensive evaluation which will report on the effectiveness of this program in practice.

A suite of visual languages for model-driven development of statistical surveys and services

Objective: To provide statistician end users with a visual language environment for complex statistical survey design and implementation. Methods: We have developed, in conjunction with professional statisticians, the Statistical Design Language (SDL), an integrated suite of visual languages aimed at supporting the process of designing statistical surveys, and its support environment, SDLTool. SDL comprises five diagrammatic notations: survey diagrams, data diagrams, technique diagrams, task diagrams and process diagrams. SDLTool provides an integrated environment supporting design, coordination, execution, sharing and publication of complex statistical survey techniques as web services. SDLTool allows association of model components with survey artefacts, including data sets, metadata, and statistical package analysis scripts, with the ability to execute elements of the survey design model to implement survey analysis. Results: We describe three evaluations of SDL and SDLTool: use of the notation by expert statistician to design and execute surveys; useability evaluation of the environment; and assessment of several generated statistical analysis web services. Conclusion: We have shown the effectiveness of SDLTool for supporting statistical survey design and implementation. Practice implications: We have developed a more effective approach to supporting statisticians in their survey design work.

A taxonomy and mapping of computer-based critiquing tools

Critics have emerged in recent times as a specific tool feature to support users in computer-mediated tasks. These computer-supported critics provide proactive guidelines or suggestions for improvement to designs, code, and other digital artifacts. The concept of a critic has been adopted in various domains, including medical, programming, software engineering, design sketching, and others. Critics have been shown to be an effective mechanism for providing feedback to users. We propose a new critic taxonomy based on extensive review of the critic literature. The groups and elements of our critic taxonomy are presented and explained collectively with examples, including the mapping of 13 existing critic tools, predominantly for software engineering and programming education tasks to the taxonomy. We believe this critic taxonomy will assist others in identifying, categorizing, developing, and deploying computer-supported critics in a range of domains.

Examples of individual supported living for adults with intellectual disability

BACKGROUND: This article provides a qualitative account of four models of support for adults with intellectual disability in individual supported living (ISL) arrangements. MATERIALS AND METHODS: Completion of the first 50 evaluations of 150 arrangements for the third phase of the ISL project provided the examples. RESULTS: Four approaches are described: living alone, co-residency, relationship and host family. Within each type, wide variations occur particularly based on security of tenure, formal and informal support and management variations. CONCLUSION: Fifty evaluations so far illustrated a wide range of approaches to ISL, providing evidence of the critical importance of the formal and informal support environment and reinforcing the contention that ISL is appropriate for people with high support needs.

Awareness support in a component-based collaborative environment

The awareness support for activities in collaborative environments is important for effective collaboration and coordination. It helps people know who else is doing what in a shared workspace. The amount of awareness needed varies due to specific roles users undertake during collaboration. While emphasizing the importance of roles, we introduced related research on awareness and a component-based collaboration metamodel. Based on that metamodel, several awareness elements were discussed and implemented in a collaborative environment LiveNet4. Model view controller pattern used to construct the Web-based interface of LiveNet4 was also introduced at the end of this paper.

Converged learning environment to support all learners

Universities face an uncertain future unless they significantly alter their teaching and learning approaches and become more client focused. They need to reach more and more students who do not fit the standard residential degree. This has meant that lecturers have had to facilitate learning for on-campus students on local and overseas campuses as well as for off-campus students based locally and globally. Given the context, flexibility has been recognised as a key idea making it imperative to explore innovative models for flexibility that bring together and accommodate and support all learner groups.

This paper describes a project to support students of an undergraduate Business Law unit via the development of such a converged learning environment. It attempts to draw together the different communities of students (on-campus and off-campus based locally and overseas) enrolled in that unit. In order to assist others interested in supporting flexible learning in a similar way, the paper shares details of formative evaluation and planned summative evaluation, together with reflections on lessons learned by the teaching academic and educational designer during its development process.
