BACKGROUND Despite being central to achieving improved population health outcomes, primary health centres in low- and middle-income settings continue to underperform. Little research exists to adequately explain how and why this is the case. This study aimed to test the relevance and usefulness of an adapted conceptual framework for improving our understanding of the mechanisms and causal pathw...

Maintaining a semantic cache of materialized XPath views inside or outside the database, is a novel, feasible and efficient approach to accelerate XML query processing. However, the main problems of existing approaches are that, they either can not exploit sufficient potential cached views to answer an issued query or need too much time for cache lookup. In this paper, we propose, SCEND, an eff...

Quora is one of the most popular community Q&A sites of recent times. However, many question posts on this Q&A site often do not get answered. In this paper, we quantify various linguistic activities that discriminates an answered question from an unanswered one. Our central finding is that the way users use language while writing the question text can be a very effective means to characterize ...

Promptly and accurately answering questions on products is important for e-commerce applications. Manually product (e.g. community question platforms) results in slow response does not scale. Recent studies show that reviews are a good source real-time, automatic (PQA). In the literature, PQA formulated as retrieval problem with goal to search most relevant answer given question. this paper, we...

Implementation often occupies a problematic position in accounts of strategy. It is often seen as a separate and low level activity. The assumption of separateness contradicts empirical evidence, while the assumption of low level activity portrays implementation as simple and automatic despite evidence that implementation often fails. We propose to resolve this difficulty by regarding implement...

In this paper, we propose a method for maintaining a semantic cache of materialized XPath views. The cached views include queries that have been previously asked, and additional selected views. The cache can be stored inside or outside the database. We describe a notion of XPath query/view answerability, which allows us to reduce tree operations to string operations for matching a query/view pa...

As a simple XML query language but with enough expressive power, XPath has become very popular. To expedite evaluation of XPath queries, we consider the problem of caching results of popular XPath queries to answer queries. Existing semantic caching systems can answer queries that have been already cached, but can’t combine cached results of multiple XPath queries to answer new queries. In this...

K-Anonymity has been proposed as a mechanism for privacy protection in microdata publishing, and numerous recoding “models” have been considered for achieving kanonymity. This paper proposes a new multidimensional model, which provides an additional degree of flexibility not seen in previous (single-dimensional) approaches. Often this flexibility leads to higher-quality anonymizations, as measu...
