Complexity Theory, Adaptation, and Administrative Law

Recently, commentators have applied insights from complexity theory to legal analysis generally and to administrative law in particular. This Article focuses on one of the central problems that complexity. theory addresses, the importance and mechanisms of adaptation within complex systems. In Part I, the Article uses three features of complex adaptive systems-emergence from self-assembly, nonlinearity, and sensitivity to initial conditions-and explores the extent to which they may add value as a matter of positive analysis to the understanding of change within legal systems. In Part H, the Article focuses on three normative claims in public law scholarship that depend explicitly or implicitly on notions of adaptation: that states offer advantages over the federal government because experimentation can make them more adaptive, that federal agencies should themselves become more experimentalist using the tool of adaptive management, and that administrative agencies shou Id adopt collaborative mechanisms in policymaking. Using two analytic tools found in the complexity literature, the genetic algorithm and evolutionary game theory, the Article tests the extent to which these three normative claims are borne out

The Case for a Cooperative Studio Classroom: Teaching Petrology in a Different Way

NOTE: This file size is large, 16.52 mb. This article describes one educator's attempts to modify his Petrology course, changing the lab-lecture format to one that emphasizes studio and cooperative learning. The goals of the changes are to improve student learning by covering a smaller number of topics in greater depth, deemphasize knowledge-based learning and emphasize development of higher order thinking skills (comprehension, application, analysis, synthesis, evaluation), and help students develop good habits of the mind and fundamental skills useful for lifelong learning. The reformatted course requires that students take more responsibility for their learning. Educational levels: Graduate or professional

Specifying computer-supported collaboration scripts

Collaboration scripts are activity programs which aim to foster collaborative learning by structuring interaction between learners. Computer-supported collaboration scripts generally suffer from the problem of being restrained to a specific learning platform and learning context. A standardization of collaboration scripts first requires a specification of collaboration scripts that integrates multiple perspectives from computer science, education and psychology. So far, only few and limited attempts at such specifications have been made. This paper aims to consolidate and expand these approaches in light of recent findings and to propose a generic framework for the specification of collaboration scripts. The framework enables a description of collaboration scripts using a small number of components (participants, activities, roles, resources and groups) and mechanisms (task distribution, group formation and sequencing)

Defining the mechanisms of a cooperative computer system based on theories of cooperation

There is a growing interest in the development of computer systems that are actively involved in the tasks of the users and serve to augment the users' creativity. Cooperative computing is a major contribution to this research field. A survey of current developments in knowledge based systems led to the conclusion that there has hitherto been an absence of a formal definition of the mechanisms of cooperative computer systems based on theories of cooperation. The work in this thesis seeks to provide a full definition of cooperation derived from the behaviours of living cooperative systems. Studies on human cooperation and cooperation in the animal kingdom, established that cooperation is a dynamic behaviour; in that the interaction processes between the cooperative partners serve to facilitate the achievement of a common goal, or a set of goals that are mutually desired by the partners. Partners in cooperation are interdependent: one member's actions are contingent on another. Therefore, the underlying processes which induce and maintain cooperation were identified. These are: communication between the partners; emergence of norms and roles governing the behaviour of the cooperating members; resolution of conflicts; distributed and coordinated activities. These factors were further elucidated within the context of small problem solving groups. A model of cooperationw hich encapsulatedth esef actors was produced. From the discussionso f the advantageso f cooperationw ithin different contexts, the potential for synergy was found to be the main benefit of cooperation. The potential for achieving this synergy between a human and a computer is the main motivation for the work undertaken in this research. From the theoretical analysis of cooperation, the underlying mechanisms of a cooperative computer were successfully defined. A conceptual model of human-computer cooperation was presented. It was established that the quality of cooperation is closely associated with the nature of the task. Therefore, it is not practicable to produce a general purpose cooperative system. A specific task must be used. Creative tasks of a problem identifying and solving nature, were found to be more suitable to cooperative behaviour than others. Typical of these, and the one selected, was computer screen design. Current screen design practice was analysed, and the functional requirements and knowledge base needs of the systems were established. The underlying mechanisms of cooperation were formalised and successfully implemented within a software exemplar, named COSY. COSY exhibits the behavioural characteristics of cooperation, and utilises the knowledge of screen design to support users in the task of formatting computer screens. COSY successfully demonstrated the synergistic relationship in its cooperation with the users. It is concluded that the approach undertaken in this thesis has lead to a successful definition and implementation of the formal mechanisms of cooperation in a computer system, one which potentially enhances the innovative and creative aspects of design work

UNDERSTANDING THE SOCIAL AND COGNITIVE EXPERIENCES OF CHILDREN INVOLVED IN TECHNOLOGY DESIGN PROCESSES

Technology has become ubiquitous not only in the lives of adults, but also in the lives of children. For every technology, there is a process by which it is designed. In many cases, children are involved in these design processes. This study examined the social and cognitive experiences of children who were integrally involved in a technology design process in partnership with adults. This research study employed a Vygotskian lens with a case study research method, to understand the cognitive and social experiences of child technology design partners over a one-year period of design and partnership. Artifact analysis, participant observation, and interviews were used to collect and analyze data. Results from this study demonstrated that children involved in technology design process in partnership with adults experienced social and cognitive experiences which fall into the areas of relationships, enjoyment, confidence, communication, collaboration, skills, and content

Critiquing: Effective Decision Support in Time-Critical Domains (Dissertation Proposal)

The effective communication of information is an important concern in the design of an expert consultation system. Several researchers have chosen to adopt a critiquing mode, in which the system evaluates and reacts to a solution proposed by the user rather than presenting its own solution. In this proposal, I present an architecture for a critiquing system that functions in real-time, during the process of developing and executing a management plan in time-critical situations. The architecture is able to take account of and reason about multiple, interacting goals and to identify critical errors in the proposed management plan. This architecture is being implemented as part of the TraumAID system for the management of patients with severe injuries

An Action Research Study on Using Cooperative Learning During Graphic Design Classroom Crits

The author of this action research study surveyed both graphic design students and graphic design instructors about their critique experiences to discover instructors and students both identified a lack of student participation as well as the issue of students getting hurt feelings and becoming discouraged as common critique concerns. The author designed and implemented a treatment called Design Structures to increase student participation during crits. To improve the quality of experience of design students during crits, the author incorporated cooperative learning strategies developed by Spencer and Miguel Kagan (2009) into the Design Structures treatment. The author used the experience sampling method (Csikzentmihalyi, Rathunde, & Whalen, 1993) to compare the quality of experience of community college design students during whole-class crits and during Design Structures crits. Quality of experience levels were consistently higher overall for students during cooperative learning -specifically in the areas of self-esteem, perceived importance of task, challenge, and skill. Furthermore, more design students were in flow and less apathetic during decentralized crits using Design Structures than centralized crits utilizing teacher-led whole-class instruction. In fact, results showed no design students as apathetic during Design Structures crits. The author interviewed design instructors to discover their perceptions, as well as misconceptions, of cooperative learning methodology in addition to their openness to learning more about how to effectively incorporate cooperative learning into their critique pedagogy
