Data Warehouses (DWs) integrate data from different source systems that may have temporal support. However, current DWs only allow to track changes for measures indicating the time when a specific measure value is valid. In this way, applications such as fraud detection cannot be easily implemented since they require to know the time when changes in source systems have occurred. In this work, b...

Inclusion analysis is the name given by Operis to a black box testing technique that it has found to make the checking of key financial ratios calculated by spreadsheet models quicker, easier and more likely to find omission errors than code inspection. 1 CALCULATE MORE THAN ONCE One approach among many [Pryor, 2004] [Panko, 2006] for improving the chance that a spreadsheet delivers the results...

Purpose This study aims to examine whether social inclusion policies promote financial inclusion. Three were analyzed: gender equality policies, environmental sustainability and protection (SP) policies. Design/methodology/approach The used the panel fixed effect regression methodology analyze data from 48 low- medium-income countries. Findings results show that do not have a significant on Als...

BACKGROUND Studies included in a related systematic review used a variety of statistical methods to summarise clinical behaviour and to compare proxy (or indirect) and direct (observed) methods of measuring it. The objective of the present review was to assess the validity of these statistical methods and make appropriate recommendations. METHODS Electronic bibliographic databases were search...

This paper proves some results concerning the polar factorisation of an integrable vector-valued function u into the composition u = u ◦ s, where u = ∇ψ almost everywhere for some convex function ψ, and s is a measure-preserving mapping. Not every integrable function has a polar factorisation; we extend the class of counterexamples. We introduce a generalisation: u has a polar inclusion if u(x)...

We call markets in which intermediaries sell networks of suppliers to consumers who are uncertain about their needs "option demand markets." In these markets, suppliers may grant the intermediaries discounts in order to be admitted to their networks. We derive a measure of each supplier's market power within the network; the measure is based on the additional ex ante expected utility consumers ...
