The topic of Data Quality (DQ) in the field of Information Management has been extensively researched. Within this field, DQ relevant for Public Health Administration has been relatively less explored. DQ research has traditionally focused on a select set of DQ factors (e.g. timeliness or accuracy etc.), however, advances in the field of Information Management triggered by emerging technology t...

Data quality (DQ) metadata is the set of quality measurements associated with the data. Literature has demonstrated that the provision of DQ metadata can improve decision performance. However, it also showed that DQ metadata can overload decision-makers and consequently have a negative impact on decision performance. In this paper, we describe a prototype system, SPIDEQ, for visualizing DQ meta...

Economic perspectives have raised growing attention in recent data quality (DQ) literature, as studies have associated DQ decisions with major cost-benefit tradeoffs. Despite the growing interest, DQ research has not yet developed a robust, agreedupon view for assessing and studying the link between DQ and economic outcome. As a contribution, this study proposes a framework, which links costs t...

Dynamic Querying (DQ) is a technique adopted in unstructured Peer-to-Peer (P2P) networks to minimize the number of peers that is necessary to visit to reach the desired number of results. In this paper we introduce the use of the DQ technique in structured P2P networks. In particular, we present a P2P search algorithm, named DQ-DHT (Dynamic Querying over a Distributed Hash Table), to perform DQ...

Deviation of the multiplicity distribution Pq in small bin from its Poisson counterpart pq is studied within the Ginzburg-Landau description for second-order quark-hadron phase transition. Dynamical factor dq ≡ Pq/pq for the distribution and ratio Dq ≡ dq/d1 are defined, and novel scaling behaviors between Dq are found which can be used to detect the formation of quark-gluon plasma. The study o...

BACKGROUND Epitopes are the sites to which antibodies bind. Both alpha and beta peptide chains of the human leukocyte antigen-DQ heterodimers (DQA1 and DQB1, respectively) contain polymorphic regions. We can identify DQA1 and DQB1 epitopes by DQ single antigen beads assay of the antibodies, correlating the beads' reaction patterns with either DQA1 or DQB1 alleles. METHODS Sera from 74 transpl...

Data Stream Management Systems (DSMS) have been proposed to address the challenges of applications which produce continuous, rapid streams of data that have to be processed in real-time. Data quality (DQ) plays an important role in DSMS as there is usually a trade-off between accuracy and consistency on the one hand, and timeliness and completeness on the other hand. Previous work on data quali...

Research Article Rosanne Price Monash University [email protected] Graeme Shanks The University of Melbourne [email protected] It has been proposed that metadata describing data quality (DQ), termed DQ tags, be made available in situations where decision makers are unfamiliar with the data context, for example, in data warehouses. However, there have been conflicting reports as to t...

The objective of this study was to examine the impact of chronic hyperoxic exposure (95% O2 for 48 h) on intact bovine pulmonary arterial endothelial cell redox metabolism of 2,3,5,6-tetramethyl-1,4-benzoquinone (duroquinone, DQ). DQ or durohydroquinone (DQH2) was added to normoxic or hyperoxia-exposed cells in air-saturated medium, and the medium DQ concentrations were measured over 30 min. DQ...

DQ-DHT is a resource discovery algorithm that combines the Dynamic Querying (DQ) technique used in unstructured peer-to-peer networks with an algorithm for efficient broadcast over a Distributed Hash Table (DHT). Similarly to DQ, DQ-DHT dynamically controls the query propagation on the basis of the desired number of results and the popularity of the resource to be located. Differently from DQ, ...
