This research examines mechanisms underlying the primacy in processing of elements over relations. It is hypothesized that elements are detected atomatically even when the task is to ignore them, and this automatic detection may interfere with the processing of relations. In Experiment 1, 4 year-olds and adults were asked to ignore elemental features and to match a test item to a target by dete...

In order to publish a nested XML document from flat relational data, multiple SQL queries are often needed. The efficiency of publishing relies on how fast these queries can be evaluated and their results shipped to the client. We illustrate novel optimization techniques that enable computation sharing between queries that construct sibling elements in the XML tree. Such queries typically share...

Recent evidence suggests that the hippocampus may integrate overlapping memories into relational representations, or schemas, that link indirectly related events and support flexible memory expression. Here we explored the nature of hippocampal neural population representations for multiple features of events and the locations and contexts in which they occurred. Hippocampal networks developed ...

Let T be a non empty FR-structure. We say that T is lower if and only if: (Def. 1) {−↑x : x ranges over elements of T} is a prebasis of T . Let us note that every non empty reflexive topological space-like FR-structure which is trivial is also lower. One can verify that there exists a top-lattice which is lower, trivial, complete, and strict. We now state the proposition (1) For every non empty...

Visualization based on graph drawing is a powerful tool to analyze relational information evolution. It is based on big data corpora synthesis. It makes it possible to identify and to evaluate passed and current structures, and to deduce the future ones between actors and concepts. In this context, IRIT SIG team propose the strategic data analyzes platform Tetralogie and the gate Web Xplor dedi...

Spatial data can refer to elements that help place a certain object in a certain area. These elements are latitude, longitude, points, geometric figures represented by points, etc. However, when translating these elements into data that can be stored in a computer, it all comes down to numbers. The interesting part that requires attention is how to memorize them in order to obtain fast and vari...

Structured distributional semantic models aim to improve upon simple vector space models of semantics by hypothesizing that the meaning of a word is captured more effectively through its relational — rather than its raw distributional — signature. In accordance, they extend the vector space paradigm by structuring elements with relational information that decompose distributional signatures ove...

A negative database is a representation of all elements not contained in a given database. A negative database can enhance the privacy of sensitive information without resorting to encryption. This can be useful in settings where encryption is too expensive, e.g., some sensor networks, or for applications where searches or other operations on stored data are desired. The original negative datab...

Previous research has shown that vertical learning alliances help suppliers acquire knowledge to forge new capabilities and attain performance improvements. We ask whether such supplier improvements are exclusive to the learning partnership, or available in other average partnerships. We integrate theoretical elements from the resource-based and relational views to theorize that partnership exc...

Previous studies using a categorical recognition task (Sloutsky & Yarlas, 2000a, 2000b; Yarlas & Sloutsky, 2000) elicited three reliable findings in feature processing of arithmetic equations: 1) participants were capable of representing both elementary and relational features of equations, 2) elements and relations were processed serially, with elements processed prior to relations, and 3) par...
