Comfort zone: Model or metaphor?
The comfort zone model is widespread within adventure education literature. It is based on the belief that when placed in a stressful situation people will respond by overcoming their fear and therefore grow as individuals. This model is often
presented to participants prior to activities with a highly perceived sense of risk and challenge which arouses strong emotional and physical responses to novel tasks (e.g., ropes courses or rock climbing activities). Students are encouraged to think about
āstretching themselvesā by moving outside their comfort zone, to expand their preconceived limits and by inference learn (and become better people). This paper explores theories from cognitive and social psychology, based on the work of Piaget
and Festinger respectively, that underpin the comfort zone model. The perpetuation of this model which uses risk to promote situations of disequilibrium/dissonance does not find strong support in educational literature. It is therefore suggested that the comfort zone model be reframed as a metaphor, for possible discussion post activity, rather than being used as a model to
underpin programming and pedagogy in adventure education settings
Reason Maintenance - State of the Art
This paper describes state of the art in reason maintenance with a focus on its future usage in the KiWi project. To give a bigger picture of the field, it also mentions closely related issues such as non-monotonic logic and paraconsistency. The paper is organized as follows: first, two motivating scenarios referring to semantic wikis are presented which are then used to introduce the different reason maintenance techniques
Logic, self-awareness and self-improvement: The metacognitive loop and the problem of brittleness
This essay describes a general approach to building perturbation-tolerant autonomous systems, based on the conviction that artificial agents should be able notice when something is amiss, assess the anomaly, and guide a solution into place. We call this basic strategy of self-guided learning the metacognitive loop; it involves the system monitoring, reasoning about, and, when necessary, altering its own decision-making components. In this essay, we (a) argue that equipping agents with a metacognitive loop can help to overcome the brittleness problem, (b) detail the metacognitive loop and its relation to our ongoing work on time-sensitive commonsense reasoning, (c) describe specific, implemented systems whose perturbation tolerance was improved by adding a metacognitive loop, and (d) outline both short-term and long-term research agendas
Resistance to change. Exploring the convergence of institutions, organizations and the mind toward a common phenomenon
Resistance to change is not a new concept in economic literature (Coch and French 1948, Boulding 1956). However, in the last few decades it has acquired specific connotations and meanings that deserve attention. The first aim of the paper is to analyze how the concept has evolved since its introduction by Lewin (1946) and how it has diversified. Having acknowledged that resistance characterizes institutions, organizations and the mind, we suggest that the convergence toward such phenomenon is not surprising. Indeed, it may be explained by taking the bounds that affect the cognitive and emotional counterparts of economic behavior into account. We finally reinterpret resistance to change as a heuristic that helps manage the natural tendency of human beings to fear, uncertainty and its expected effects.Change - cognitive economics - heuristic - emotions - resistance
A Guide to Kantās Treatment of Grace
This Guide is designed to restore the theological background that informs Kantās treatment of grace in Religion to its rightful place. This background is essential not only to understand the nature of Kantās overall project in this book, namely, to determine the āassociationā or āunionā between Christianity (as a historical faith) and rational religion, but also to dispel the impression of āinternal contradictionsā and conundrumsā that contemporary interpreters associate with Kantās treatment of grace and moral regeneration. That impression, we argue, is the result of entrenched interpretative habits that can be traced back to Karl Barthās reading of the text. Once we realize that such a reading rests on a mistake, much of the anxiety and confusion that plague current discussions on these issues can be put to rest
Verification of knowledge shared across design and manufacture using a foundation ontology
Seamless computer-based knowledge sharing between departments of a manufacturing enterprise is useful in preventing unnecessary design revisions. A lack of interoperability between independently developed knowledge bases, however, is a major impediment in the development of a seamless knowledge sharing system. Interoperability, being an ability to overcome semantic and syntactic differences during computer-based knowledge sharing can be enhanced through the use of ontologies. Ontologies in computer science terms are hierarchical structures of knowledge stored in a computer-based knowledge base. Ontologies have been accepted by all as an interoperable medium to provide a non-subjective way of storing and sharing knowledge across diverse domains. Some semantic and syntactic differences, however, still crop up when these ontological knowledge bases are developed independently. A case study in an aerospace components manufacturing company suggests that shape features of a component are perceived differently by the designing and manufacturing departments. These differences cause further misunderstanding and misinterpretation when computer-based knowledge sharing systems are used across the two domains. Foundation or core ontologies can be used to overcome these differences and to ensure a seamless sharing of knowledge. This is because these ontologies provide a common grounding for domain ontologies to be used by individual domains or department. This common grounding can be used by the mediation and knowledge verification systems to authenticate the meaning of knowledge understood across different domains. For this reason, this research proposes a knowledge verification framework for developing a system capable of verifying knowledge between those domain ontologies which are developed out of a common core or foundation ontology. This framework makes use of ontology logic to standardize the way concepts from a foundation and core-concepts ontology are used in domain ontologies and then by using the same principles the knowledge being shared is verified. The Knowledge Frame Language which is based on Common Logic is used for formalizing example ontologies. The ontology editor used for browsing and querying ontologies is the Integrated Ontology Development Environment (IODE) by Highfleet Inc. An ontological product modelling technique is also developed in this research, to test the proposed framework in the scenario of manufacturability analysis. The proposed framework is then validated through a Java API specially developed for this purpose. Real industrial examples experienced during the case study are used for validation

Set-related restrictions for semantic groupings
Semantic database models utilize several fundamental forms of groupings to increase their expressive power. In this paper we consider four of the most common of these constructs; basic set groupings, is-a related groupings, power set groupings, and Cartesian aggregation groupings. For each, we define a number of useful restrictions that control its structure and composition. This permits each grouping to capture more subtle distinctions of the concepts or situations in the application environment. The resulting set of restrictions forms a framework which increases the expressive power of semantic models and specifies various set-related integrity constraints
An extensible benchmark and tooling for comparing reverse engineering approaches
Various tools exist to reverse engineer software source code and generate design information, such as UML projections. Each has specific strengths and weaknesses, however no standardised benchmark exists that can be used to evaluate and compare their performance and effectiveness in a systematic manner. To facilitate such comparison in this paper we introduce the Reverse Engineering to Design Benchmark (RED-BM), which consists of a comprehensive set of Java-based targets for reverse engineering and a formal set of performance measures with which tools and approaches can be analysed and ranked. When used to evaluate 12 industry standard tools performance figures range from 8.82\% to 100\% demonstrating the ability of the benchmark to differentiate between tools. To aid the comparison, analysis and further use of reverse engineering XMI output we have developed a parser which can interpret the XMI output format of the most commonly used reverse engineering applications, and is used in a number of tools
Educational potential of teaching evolution as an interdisciplinary science
Evolution education continues to struggle with a range of persistent challenges spanning aspects of conceptual understanding, acceptance, and perceived relevance of evolutionary theory by students in general education. This article argues that a gene-centered conceptualization of evolution may inherently limit the degree to which these challenges can be effectively addressed, and may even precisely contribute to and exacerbate these challenges. Against that background, we also argue that a trait-centered, generalized, and interdisciplinary conceptualization of evolution may hold significant learning potential for advancing progress in addressing some of these persistent challenges facing evolution education. We outline a number of testable hypotheses about the educational value of teaching evolutionary theory from this more generalized and interdisciplinary conception
