Flexibly Instructable Agents

This paper presents an approach to learning from situated, interactive tutorial instruction within an ongoing agent. Tutorial instruction is a flexible (and thus powerful) paradigm for teaching tasks because it allows an instructor to communicate whatever types of knowledge an agent might need in whatever situations might arise. To support this flexibility, however, the agent must be able to learn multiple kinds of knowledge from a broad range of instructional interactions. Our approach, called situated explanation, achieves such learning through a combination of analytic and inductive techniques. It combines a form of explanation-based learning that is situated for each instruction with a full suite of contextually guided responses to incomplete explanations. The approach is implemented in an agent called Instructo-Soar that learns hierarchies of new tasks and other domain knowledge from interactive natural language instructions. Instructo-Soar meets three key requirements of flexible instructability that distinguish it from previous systems: (1) it can take known or unknown commands at any instruction point; (2) it can handle instructions that apply to either its current situation or to a hypothetical situation specified in language (as in, for instance, conditional instructions); and (3) it can learn, from instructions, each class of knowledge it uses to perform tasks.Comment: See http://www.jair.org/ for any accompanying file

Argument maps as policy memories for informed deliberation: A research note

This is an eGISE network paper. A significant area within eGovernment is concerned with systems to support democratic policy formation and decision making processes. In modern government, both local and national, consultation with interested parties is an important element in maintaining the democratic process. To date online consultation tools have has used existing software tools, which are simple text based tools that were not tailored to the process. This project proposes to develop an online tool that will visualise the issues and arguments graphically as the consultation process proceeds. Using Discourse Analysis and Ontological Engineering it will create Argument Maps that will server not only to inform participants but also the archive record of the consultation – the Policy Memory. We hypothesise that such a tool would allow citizens to be come more engaged with policy formation and enhance democratic participation

Citizen Participation in Rulemaking: Past, Present, and Future

Administrative law scholars and governmental reformers argue that advances in information technology will greatly expand public participation in regulatory policymaking. They claim that e-rulemaking, or the application of new technology to administrative rulemaking, promises to transform a previously insulated process into one in which ordinary citizens regularly provide input. With the federal government having implemented several e-rulemaking initiatives in recent years, we can now begin to assess whether such a transformation is in the works-or even on the horizon. This paper compares empirical observations on citizen participation in the past, before e-rulemaking, with more recent data on citizen participation after the introduction of various types of technological innovations. Contrary to prevailing predictions, empirical research shows that e-rulemaking makes little difference: citizen input remains typically sparse, notwithstanding the relative ease with which individuals can now learn about and comment on regulatory proposals. These findings indicate that the more significant barriers to citizen participation are cognitive and motivational. Even with e-rulemaking, it takes a high level of technical sophistication to understand and comment on regulatory proceedings. Moreover, even though information technology lowers the absolute cost of submitting comments to regulatory agencies, it also dramatically decreases the costs of a wide variety of entertainment and commercial activities that are much more appealing to most citizens. Given persistent opportunity costs and other barriers to citizen participation, even future e-rulemaking efforts appear unlikely to lead to a participatory revolution, but instead can be expected generally to deliver much the same level of citizen involvement in the regulatory process

Towards a personal best : a case for introducing ipsative assessment in higher education

The central role that assessment plays is recognised in higher education, in particular how formative feedback guides learning. A model for effective feedback practice is used to argue that, in current schemes, formative feedback is often not usable because it is strongly linked to external criteria and standards, rather than to the processes of learning. By contrast, ipsative feedback, which is based on a comparison with the learner's previous performance and linked to longterm progress, is likely to be usable and may have additional motivational effects. After recommending a move towards ipsative formative assessment, a further step would be ipsative grading. However, such a radical shift towards a fully ipsative regime might pose new problems and these are discussed. The article explores a compromise of a combined assessment regime. The rewards for learners are potentially high, and the article concludes that ipsative assessment is well worth further investigation. © 2011 Society for Research into Higher Education

Principles in Patterns (PiP) : Heuristic Evaluation of Course and Class Approval Online Pilot (C-CAP)

The PiP Evaluation Plan documents four distinct evaluative strands, the first of which entails an evaluation of the PiP system pilot (WP7:37). Phase 1 of this evaluative strand focuses on the heuristic evaluation of the PiP Course and Class Approval Online Pilot system (C-CAP). Heuristic evaluation is an established usability inspection and testing technique and is most commonly deployed in Human-Computer Interaction (HCI) research, e.g. to test user interface designs, technology systems testing, etc. The success of heuristic evaluation in detecting 'major' and 'minor' usability problems is well documented, but its principal limitation is its inability to capture data on all possible usability problems. For this reason heuristic evaluation is often used as a precursor to user testing, e.g. so that user testing focuses on deeper system issues rather than on those that can easily be debugged. Heuristic evaluation nevertheless remains an important usability inspection technique and research continues to demonstrate its success in detecting usability problems which would otherwise evade detection in user testing sessions. For this reason experts maintain that heuristic evaluation should be used to complement user testing. This is reflected in the PiP Evaluation Plan, which proposes protocol analysis, stimulated recall and pre- and post-test questionnaire instruments to comprise user testing (see WP7:37 phases 2, 3 and 4 of PiP Evaluation Plan). This brief report summarises the methodology deployed, presents the results of the heuristic evaluation and proposes solutions or recommendations to address the heuristic violations that were found to exist in the C-CAP system. It is anticipated that some solutions will be implemented within the lifetime of the project. This is consistent with the incremental systems design methodology that PiP has adopted

Power, norms and institutional change in the European Union: the protection of the free movement of goods

How do institutions of the European Union change? Using an institutionalist approach, this article highlights the interplay between power, cognitive limits, and the normative order that underpins institutional settings and assesses their impact upon the process of institutional change. Empirical evidence from recent attempts to reinforce the protection of the free movement of goods in the EU suggests that, under conditions of uncertainty, actors with ambiguous preferences assess attempts at institutional change on the basis of the historically defined normative order which holds a given institutional structure together. Hence, path dependent and incremental change occurs even when more ambitious and functionally superior proposals are on offer

The politics of IMF–EU cooperation : institutional change from the Maastricht Treaty to the launch of the Euro

How do regional changes affect the process of global governance? This article addresses this question by examining how the International Monetary Fund (IMF) responded to the challenges presented by Economic and Monetary Union (EMU) between the signing of the Maastricht Treaty in 1992 and the launch of the euro in 1999. Based on primary research from the IMF archives, the article illustrates how the IMF's efforts to reconfigure its relationship with European institutions evolved gradually through a logic of incremental change, despite initial opposition from member states. The article concludes that bureaucratic actors within international organizations will take advantage of informal avenues for promoting a new agenda when this fits with shared conceptions of an organization's mandate. The exercise of informal influence by advocates for change within an international organization can limit the options available to states in formal decision-making processes, even when these options cut across state preferences

Smarter Programming of the Female Condom: Increasing Its Impact on HIV Prevention in the Developing World

The purpose of this study was to investigate the relative value of the female condom for HIV prevention within heterosexual relationships in the developing world. In the last ten years, the world has witnessed both historic financial commitments to HIV/AIDS and new prevention options, including biomedical prevention research, male circumcision, and a dramatic scale-up of voluntary counseling and testing. At the same time, where HIV remains at epidemic levels in many countries, there has been a growing commitment to treatment access alongside prevention programs. However, portions of populations, particularly youth and women, remain highly vulnerable to HIV infection. Accordingly, the global health community can benefit from a better understanding of how existing prevention options should be effectively and efficiently delivered to reduce HIV in the developing world. This report provides guidance for the global health community for considering how the female condom fits within the set of prevention interventions currently available

The Correlation Between Ecclesial Communion and the Recognition of Ministry

Recognition of an imperfect communion between churches, the recognition of ecclesial communities as churches, and the mutual recognition of ministry are treated as separate and discrete topics in ecumenical conversations. Nevertheless, an ecclesiology of communion suggests that ecclesial recognition and recognition of ministry within a relationship of imperfect communion should be correlated with each other in such a way that an imperfect ecclesial communion contributes to an incremental recognition of ministry in ecumenical relationships. This essay explores this question with specific references to the concept of communion in Chapter II, part D and E of the World Council of Churches document, The Church: Towards a Common Vision (2013)

A holistic multi-methodology for sustainable renovation

A review of the barriers for building renovation has revealed a lack of methodologies, which can promote sustainability objectives and assist various stakeholders during the design stage of building renovation/retrofitting projects. The purpose of this paper is to develop a Holistic Multi-methodology for Sustainable Renovation, which aims to deal with complexity of renovation projects. It provides a framework through which to involve the different stakeholders in the design process to improve group learning and group decision-making, and hence make the building renovation design process more robust and efficient. Therefore, the paper discusses the essence of multifaceted barriers in building renovation regarding cultural changes and technological/physical changes. The outcome is a proposal for a multi-methodology framework, which is developed by introducing, evaluating and mixing methods from Soft Systems Methodologies (SSM) with Multiple Criteria Decision Making (MCDM). The potential of applying the proposed methodology in renovation projects is demonstrated through a case study
