Effect of Canal Length and Curvature on Working Length Alteration with WaveOne Reciprocating Files
No full textThe article “Effect of Canal Length and Curvature on Working Length Alteration with WaveOne Reciprocating Files” by Elio Berutti, Giorgio Chiandussi, Davide Salvatore Paolino, Nicola Scotti, Giuseppe Cantatore, Arnaldo Castellucci and Damiano Pasqualini (J Endod 37[12]:1687–90; 2011] should have included this statement in the author information section: “Giuseppe Cantatore, Arnaldo Castellucci, and Elio Berutti declare that they have financial involvement (patent licensing arrangements) with Dentsply Maillefer with direct financial interest in the materials discussed in this article.” In addition, Dentsply provided some of the instruments used in this study." The authors regret this omission
An assessment of worldwide airline productivity for the years 1980-2013
No full textThis paper applies a stochastic frontier analysis approach to a sample of 77 worldwide airlines for the period 1980-2013. We compute and decompose the total factor productivity growth into efficiency, technical and scale efficiency change. Our results show that on average airlines increased productivity over the period. Efficiency and technical change improved, while scale efficiency shows that the average airline moves away from the most productive scale size (especially in the first two decades). Comparison between geographical area, business models, network and alliances are also provided
Price asymmetries in European airfares
No full textThis research analyses airlines' pricing decisions in response to changes in the market conditions. We estimate the effects of jet fuel price changes on European airfares at airline/route level by discriminating on the grounds of supplied capacity and markets’ competitive structure. Our results show that airlines tend to adjust fares asymmetrically following a “rocket and feather” behaviour. The asymmetric pricing is marked in periods of decreasing capacity when the increases of fuel price are passed at a higher degree than fuel cost savings. In contrast, when capacity increases the asymmetry is lowered. Moreover, we show that highly competitive markets are characterized by a lower price asymmetry compared to low competition markets. Finally, our results show that airline price asymmetry reaches its maximum when capacity is reduced and competition is low
SCOTTI: Efficient Reconstruction of Transmission within Outbreaks with the Structured Coalescent.
No full textExploiting pathogen genomes to reconstruct transmission represents a powerful tool in the fight against infectious disease. However, their interpretation rests on a number of simplifying assumptions that regularly ignore important complexities of real data, in particular within-host evolution and non-sampled patients. Here we propose a new approach to transmission inference called SCOTTI (Structured COalescent Transmission Tree Inference). This method is based on a statistical framework that models each host as a distinct population, and transmissions between hosts as migration events. Our computationally efficient implementation of this model enables the inference of host-to-host transmission while accommodating within-host evolution and non-sampled hosts. SCOTTI is distributed as an open source package for the phylogenetic software BEAST2. We show that SCOTTI can generally infer transmission events even in the presence of considerable within-host variation, can account for the uncertainty associated with the possible presence of non-sampled hosts, and can efficiently use data from multiple samples of the same host, although there is some reduction in accuracy when samples are collected very close to the infection time. We illustrate the features of our approach by investigating transmission from genetic and epidemiological data in a Foot and Mouth Disease Virus (FMDV) veterinary outbreak in England and a Klebsiella pneumoniae outbreak in a Nepali neonatal unit. Transmission histories inferred with SCOTTI will be important in devising effective measures to prevent and halt transmission
