Breakdown curves of carbon-based molecules for astrochemistry

Breakdown curves (BDC), which are energy dependent fragmentation branching ratios, constitute a kind of "identity card" of an excited molecule or cluster. We developed a method for constructing semi-empirical BDC, based on fragmentation measurements and structural known quantities of the considered species. Calculations of BDC have been performed within the statistical M3C theory. We will present a comparison of the two methods for some species and discuss application of these results to astrochemistr

Yield Management, Dynamic Pricing and CRM in Telecommunications

The purpose of this paper is to show how yield management and dynamic pricing, which originated in the airline industry, are now diffusing in other service industries. The aim is to demonstrate that these techniques can be profitably applied to telecommunications and similar sectors and to examine the particular conditions of their implementation, development and efficiency

Just in time' pricing strategies in services: towards a concept of `customized management of service supply'

This article proposes a methodology based on capacity management and dynamic pricing strategies by questioning some of the traditional assumptions of Yield Management as they were first developed in the field of air transportation and extend the analysis to telecommunications and similar service sectors. Bearing in mind that the influence of dynamic pricing is not limited to the sole optimization of short term revenues but also applies to operations management and to long term investment policy, the authors present and discuss the concept of ‘just in time’ pricing strategies which aims at reaching a better compromise between the capacity of a company and demand in an environment where services cannot be sold in advance. In applying the concept to telecommunications, the authors then emphasize and demonstrate the strategic importance for a service company to have full command of its database and information networks and present the concept of ‘customized management of services supply’

Cross-Country Analysis of Price Levels and Dispersion in Online and Offline Environments. An Empirical Analysis in France and Germany

Our research paper takes into consideration the country effect in online and offline environments and compares price levels and dispersion online vs. offline across the two largest Continental European markets, thus adding a new dimension in price comparisons and multichannel pricing strategies. Based on an empirical analysis of data collected in one product category (CDs), our findings for France and Germany show that price levels -including shipping costs- are always higher online than offline in each country and price dispersion is persistent across markets. Calculating mean prices for the two countries, ANOVA tests reveal significant differences among the two sets of data. Using standard deviation as the measurement for price dispersion, Levene statistics reveal a higher degree of online price dispersion than offline and statistically significant differences between the two sample countries. Even if our approach need to be extended to more product categories and more countries, our article may be interesting for practitioners, policy makers and managers. It clearly shows that the \u201cfrictionless capitalism and cost transparency hypothesis\u201d has proven to be wrong most of the time even if many retailers still believe they must sacrifice the possibility of pricing up when they go on the internet. As demonstrated by our findings, retailers can take advantage of online relative indifference to price to capture some margin premium and enjoy excellent results. Our results also demonstrate that, even if results show some similarities and common trends, differences among France and Germany still remain important. As a consequence, marketers should continue to approach the European marketplace with full awareness of its diversity

A Cross European Comparison of Price Levels and Price Dispersion Among Bricks-and-Clicks, Pure Play and Multichannel Retailers

the paper offers a comparison of internet pricing strategies of three different types of retailers: online, multichannel and traditional retailers. An empirical analysis is developed in France and Ital
