A canonically defined mod 2 linear dependency current is associated to each collection ν of sections, ν 1 , ..., ν m , of a real rank n vector bundle. This current is supported on the linear dependency set of ν. It is defined whenever the collection ν satisfies a weak measure theoretic condition called " atomicity ". Essentially any reasonable collection of sections satisfies this condition, va...

This paper uses the tools of information theory to examine and reason about the information content of the attributes within a relation instance. For two sets of attributes, an information dependency measure (InD measure) characterizes the uncertainty remaining about the values for the second set when the values for the rst set are known. A variety of arithmetic inequalities (InD inequalities) ...

The paper presents the Meaning-Text linguistic theory, a theoretical framework for the construction of models of natural languages, called Meaning-Text Models. Since its beginnings, in the 1960’s, the Meaning-Text theory has placed strong emphasis on semantics and considered natural language primarily as a tool for expressing meaning. This basic insight underlies its interest in linguistic synt...

What can time-travel cases tell us about rational choice? In particular, what can we learn about rational choice from what we may call retroactive choice situations, that is, from time-travel cases in which the circumstances where an agent makes a choice depend causally on the choice the agent makes? Such cases have been thought to call into question the dominant theory of rational choice among...

We consider here scalar aggregation queries in databases that may violate a given set of functional dependencies. We show how to compute consistent answers (answers true in every minimal repair of the database) to such queries. We provide a complete characterization of the computational complexity of this problem. We also show how tractability can be obtained in several special cases (one invol...

We investigate the extent to which syntactic choice in written English is influenced by processing considerations as predicted by Gibson's (2000) Dependency Locality Theory (DLT) and Surprisal Theory (Hale, 2001; Levy, 2008). A long line of previous work attests that languages display a tendency for shorter dependencies, and in a previous corpus study, Temperley (2007) provided evidence that th...

In this paper, we propose a Connectivedriven Dependency Tree (CDT) scheme to represent the discourse rhetorical structure in Chinese language, with elementary discourse units as leaf nodes and connectives as non-leaf nodes, largely motivated by the Penn Discourse Treebank and the Rhetorical Structure Theory. In particular, connectives are employed to directly represent the hierarchy of the tree...

This study investigates the relationships between U.S. buying firms’ supplier development efforts, commitment, social capital accumulation with key suppliers, and buying firm performance. We identify linkages between supply chain management research on supplier development and organization theory research on social capital to consider how buying firm commitment to a long-term relationship, cogn...

3 theoretical approaches to the origin and development o f the infant-mother relationship are reviewed: psychoanalytic theories of object relations, social learning theories of dependency (and attachment), and an ethologically oriented theory o f attachment. "Object relations," "dependency," and "attachment," although overlapping, are seen to differ substantially. Among the concepts in regard t...
