We characterize those functions f : C → C definable in o-minimal expansions of the reals for which the structure (C,+, f) is strongly minimal: such functions must be complex constructible, possibly after conjugating by a real matrix. In particular we prove a special case of the Zilber Dichotomy: an algebraically closed field is definable in certain strongly minimal structures which are definabl...

Unit of analysis is a methodological staple in the constitution any learning theory, determining how different frameworks lead to kinds empirical observation. In this regard, emerging ecological—sociocultural and situative—approaches have been distinguished from more classical that their units are said expand beyond individual include social contexts or environments. However, elaborations on un...

In ontology-based data access (OBDA), ontologies are used as an interface for querying instance data. Since in typical applications the size of the data is much larger than the size of the ontology and query, data complexity is the most important complexity measure. In this paper, we propose a new method for investigating data complexity in OBDA: instead of classifying whole logics according to...

Throughout the computer graphics literature, but in modeling and animation lore in particular, the prevalent attitude seems to be that scripting and interaction are ir· reconcilably different types of user interface. This paper propounds the belief that this dichotomy is a myth and gives examples of systems which encourage thi8 belief. Two of the systems described are a keyframe animation progr...
