Knowledge/geometry-based Mobile Autonomous Robot Simulator (KMARS)
Ongoing applied research is focused on developing guidance system for robot vehicles. Problems facing the basic research needed to support this development (e.g., scene understanding, real-time vision processing, etc.) are major impediments to progress. Due to the complexity and the unpredictable nature of a vehicle's area of operation, more advanced vehicle control systems must be able to learn about obstacles within the range of its sensor(s). A better understanding of the basic exploration process is needed to provide critical support to developers of both sensor systems and intelligent control systems which can be used in a wide spectrum of autonomous vehicles. Elcee Computek, Inc. has been working under contract to the Flight Dynamics Laboratory, Wright Research and Development Center, Wright-Patterson AFB, Ohio to develop a Knowledge/Geometry-based Mobile Autonomous Robot Simulator (KMARS). KMARS has two parts: a geometry base and a knowledge base. The knowledge base part of the system employs the expert-system shell CLIPS ('C' Language Integrated Production System) and necessary rules that control both the vehicle's use of an obstacle detecting sensor and the overall exploration process. The initial phase project has focused on the simulation of a point robot vehicle operating in a 2D environment
Looking ahead to the future of GeogEd: creating spaces of exchange between communities of practice
As part of the special issue marking the transition of the Higher Education Research Group to the Geography and Education Research Group, in this final paper we argue that the reformed group has a key role to play in promoting spaces of exchange between the communities of practice that have a stake in the shared endeavours of geography and education. We draw on structured conversations from the group’s launch event, existing literature, and our particular vantage points to identify a range of influences – both heritages that we work with and challenges that we face – that shape the interplay of geography and education in our pedagogical contexts. We argue that the GeogEd Research Group can create spaces of productive exchange between three communities of practice: geographies of education research, geography education research, and pedagogic research. As the research group brings these communities of practice together, it facilitates dialogue, creates new avenues for research, and connects and enhances geography teaching practice across education levels

Bringing 'place' back in: regional clusters, project governance, and new product outcomes
We examine new product outcomes in the context of regional clusters. Based on past research on marketing relationships, clusters, and social networks, we propose that the overall configuration of a cluster helps promote particular governance practices among its members. These practices have distinct value-creating properties, and when they are brought to bear on a specific new product development project within a cluster, they promote performance outcomes like product novelty and speed to market. Ultimately, these performance effects are reinforced by the configuration of the cluster itself. In general, we propose that new product outcomes follow from complex interactions between a cluster's macro-level configuration and its micro-level governance processes. More broadly, our framework points to the importance of geographical variables and to the role of “place” in marketing decision-making
Assumption without representation: the unacknowledged abstraction from communities and social goods
We have not clearly acknowledged the abstraction from unpriceable “social goods” (derived from
communities) which, different from private and public goods, simply disappear if it is attempted to
market them. Separability from markets and economics has not been argued, much less established.
Acknowledging communities would reinforce rather than undermine them, and thus facilitate
the production of social goods. But it would also help economics by facilitating our understanding
of – and response to – financial crises as well as environmental destruction and many social problems,
and by reducing the alienation from economics often felt by students and the public
