A mid-level approach to modeling scientific communities

A socio-epistemic approach to identify communities of scientific collaboration

The processes that drive collaboration in scientific environments are embedded within the social, technical, cultural and epistemic practices of the constituent research communities. This poster presents a methodology to unpack specific social and epistemic dimensions of scientific collaboration using, as a case study, a “little science” research center: the Center for Embedded Networked Sensin...

A Mid-Level Approach to Contour-based Categorical Object Recognition

This paper proposes a method for detecting generic classes of objects from their representative contours that can be used by a robot with vision to find objects in cluttered environments. The approach uses a mid-level image operator to group edges into contours which likely correspond to object boundaries. This mid-level operator is used in two ways, bottom-up on simple edges and top-down incor...

Moral mid-level principles in modeling

Modeling plays a substantial role in decision-making and therefore many models raise moral issues. Modelers, especially in operations research, become increasingly aware that this poses new problems to modeling. This paper addresses two questions: (1) How do moral issues in modeling arise? (2) How can these moral issues be resolved? In this article I trace the origins of moral issues in modelin...

A Metaphysiological Approach to Modeling Ecological Populations and Communities

A Cybernetic Approach to the Modeling of Agent Communities

In an earlier paper [ 1] examples of agent technology in a NASA context were presented. Both groundbased and space-based applications were addressed. This paper continues the discussion of one aspect of the Goddard Space Flight Center's continuing efforts to develop a community of agents that can support both ground-based and space-based systems autonomy. The paper focuses on an approach to age...
