Local XML functional dependencies

Proceedings of the fifth ACM international workshop on Web information and data management - WIDM '03, 2003
Keys and functional dependencies play a fundamental role in relational databases where they are used in integrity enforcement and in database design. Similarly, these constraints will play a fundamental role in XML and recently keys and functional dependencies in XML have been defined.

A Unified Hierarchy for Functional Dependencies, Conditional Functional Dependencies and Association Rules

2009
Conditional Functional Dependencies (CFDs) are Functional Dependencies (FDs) that hold on a fragment relation of the original relation. In this paper, we show the hierarchy between FDs, CFDs and Association Rules (ARs): FDs are the union of CFDs while CFDs are the union of ARs.

Neuropsychological functioning and alcohol dependence

Current Opinion in Psychiatry, 2005
Alcohol dependence is a significant challenge to society and health-care services. The associated cognitive deficits are thought to affect behavioral control, therapy and liability to relapse. The present review demonstrates important new findings.Recent interest focused on compensatory functional circuits, components of executive functioning ...
