An usual assumption underlying the use of wavelet shrinkage is that the regression function is assumed to be either periodic or symmetric. However, such an assumption is not always realistic. This paper proposes an e5ective method for correcting the boundary bias introduced by the inappropriateness of such periodic or symmetric assumption. The idea is to combine wavelet shrinkage with local pol...

According to literature, penetration pricing is the dominant pricing strategy for network effect markets. In this paper we show that diffusion of products in a network effect market does not only vary with the set of pricing strategies chosen by competing vendors but also strongly depends on the topological structure of the customers' network. This stresses the inappropriateness of classical "i...

In recent years, a local, or even grammatical analysis of implicatures has gained popularity in pragmatics, especially to account for implicatures triggered by disjunctions embedded under other operators. Against this trend, in this paper a more traditional—and perhaps more Gricean—global analysis of implicatures is defended. Crucial use is made of facts, which provide a more fine-grained notio...

Using detailed statistical analysis of data taken from simulations and test-bed experiments, we have recently reported the inappropriateness of a queue-decoupling approximation that has been implicitly adopted by many distinct authors to incorporate queueing behavior in analytic models of finite load 802.11 networks. In the present paper we show that this flawed hypothesis leads to network thro...

A recent editorial in PLoS Biology by MacCallum and Hill (2006) pointed out the inappropriateness of studies evaluating signatures of positive selection based solely in single-site analyses. Therefore the rising number of articles claiming positive selection that have been recently published urges the question of how to improve the bioinformatics standards for reliably unravel positive selectio...

Background: A huge portion of health expenditure is attributed to hospital services. Thus, it is important to use the resources appropriately. Many studies have measured inappropriate admissions and hospitalizations. The aim of this study was to review them systematically and determine the pooled quantity as well as the reasons behind such admissions and hospitalizations.    Methods: PubMed, S...
