We evaluated the effects of faking on mean scores and correlations with self-reported counterproductive behavior of integrity-related personality items administered in single-stimulus and forced-choice formats. In laboratory studies, we found that respondents instructed to respond as if applying for a job scored higher than when given standard or “straight-take” instructions. The size of the me...

Analyses were performed on brain MRI scans from individuals who were frequent cannabis users (N = 10; 9 males, 1 female, mean age 21.1 +/- 2.9, range: 18-27) in adolescence and similar age and sex matched young adults who never used cannabis (N = 10; 9 males, 1 female, mean age of 23.0 +/- 4.4, range: 17-30). Cerebral atrophy and white matter integrity were determined using diffusion tensor ima...

Query folding is a technique for determining how a query may be answered using a given set of resources, which may include materialized views, cached results of previous queries, or queries answerable by other databases. The power of query folding can be considerably enhanced by taking into account integrity constraints that are known to hold on base relations. This paper describes an extension...

Database replication protocols check read-write and/or write-write conflicts. If there are none, then protocols propagate transactions to the database, assuming they will eventually commit. But commitment may fail due to integrity constraints violations. Also, the read actions of integrity checking may give raise to new conflicts. Thus, some more care must be taken if, in addition to the consis...

Assuring that system files have not been tampered with over time is a vital, but oftoverlooked, aspect of system security. File integrity checkers provide ways to assure the validity of files on a system. This paper concerns itself with a review of file integrity checkers. It pays particular attention to what the minimum requirements for an integrity checker are, the different approaches taken ...

This paper presents a solution to check referential integrity constraints and conjunctive global constraints in a relational multi database system. It also presents the experimental results obtained by implementing this solution over a PC cluster with Oracle9i DBMS. The goal of those experimentations is to measure the time spent to check global constraints in a distributed systems. The results ...
