Answering queries using views
- In PODS Conference
, 1995
"... We consider the problem of computing answers to queries by using materialized views. Aside from its potential in optimizing query evaluation, the problem also arises in applications such as Global Information Systems, Mobile Computing and maintaining physical data independence. We consider the probl ..."

Bypassing Joins in Disjunctive Queries
, 1995
"... In this paper we develop a novel optimization strategy for disjunctive queries involving join predicates. This work is an extension of our previously published approach [KMPS94] for optimizing disjunctive selection predicates by generating two output streams from selection operators: a "true&qu ..."

Disjunctive questions, intonation, and highlighting ⋆
"... This paper examines how intonation affects the interpretation of disjunctive questions. The semantic effect of a question is taken to be three-fold. First, it raises an issue. In the tradition of inquisitive semantics, we model this by assuming that a question proposes several possible updates of th ..."

are highlighted/suggested. We will introduce a compositional version of inquisitive semantics, and extend this framework in order to capture the highlighting- and suggestion potential of sentences. This will lead to a systematic account of the answerhood conditions and implications of disjunctive questions
On Disjunctive Cuts for Combinatorial Optimization
- J. OF COMB. OPT
, 2000
"... In the successful branch-and-cut approach to combinatorial optimization, linear inequalities are used as cutting planes within a branch-and-bound framework. Although researchers often prefer to use facet-inducing inequalities as cutting planes, good computational results have recently been obtaine ..."

Why the disjunction in quantum logic is not classical
- Foundations of Physics
, 2000
"... In this paper, the quantum logical ``or' ' is analyzed from a physical perspective. We show that it is the existence of EPR-like correlation states for the quantum mechanical entity under consideration that make it nonequivalent to the classical situation. Specifically, the presence of pot ..."

Parallel solution of disjunctive minlp problems
- Chem. Eng. Comm
, 2000
"... www.abo.fi/∼jbjorkqv In this paper, a system for parallel solution of large scale disjunctive optimization problems is presented. Disjunctive optimization problems occur in process engineering; both in production scheduling and in process synthesis. In general these problems are computationally very ..."

Splitting Heuristics for Disjunctive Numerical Constraints
"... Numerical constraint solving techniques operate in a branch& prune fashion, using consistency enforcement techniques to prune the search space and splitting operations to explore it. Extensions address disjunctions of constraints as well, but usually in a restrictive case and not fitting well th ..."

First experi-ments on CNF formulas show that interesting solving time gains can be achieved by choosing the right splitting points.
Hierarchical Knowledge Bases and Efficient Disjunctive Reasoning
, 1989
"... We combine ideas from relation-based data management with class hierarchies to obtain Hierarchical Knowledge Bases, which have greater expressive power while maintaining the benefits of predictable and efficient information processing. We then consider the problem of reasoning with certain limited f ..."

Cognitive and affective development in adolescence
- Trends in Cognitive Sciences 9: 69–74
, 2005
"... Questions about the nature of normative and atypical development in adolescence have taken on special significance in the last few years, as scientists have begun to recast old portraits of adolescent behavior in the light of new knowledge about brain development. Adolescence is often a period of es ..."

Taken together, these developments reinforce the emerging
Linguistic-pragmatic factors in interpreting disjunctions. Thinking and Reasoning
- in Thinking and Reasoning, 8(4
, 2002
"... The connective or can be treated as an inclusive disjunction or else as an exclusive disjunction. Although researchers are aware of this distinction, few have examined the conditions under which each interpretation should be anticipated. Based on linguistic-pragmatic analyses, we assume that interpr ..."
