B2C eCommerce Strategy and Market Structure: The Survey Based Approach

This paper follows two objectives: (i) It demonstrates the merits of the survey based approach to B2C eCommerce characteristics and company strategy, and (ii) it presents empirical evidence of the crucial importance of size and marketing investment in B2C eCommerce markets. It presents econometric estimates of the effects of company characteristics and company strategies on the performance of Viennese B2C eCommerce companies in 2001. We provide econometric analysis of three dependent variables in turn: (i) number of B2C eCommerce customers in 2000, (ii) number of B2C eCommerce employees in January 2001 and (iii) revenue growth rate in 2001. The models do explain the data quite well: Size as well as endogenous sunk costs emerge as the main success factors. Furthermore, the results of nonparametric tests are presented. They mostly confirm the econometric evidence. We also show that the quantitative results are consistent with the qualitative results of the surveys. Finally, we argue that the survey based approach to B2C eCommerce is a method that provides reliable and consistent data, and that it complements the approach based on prices and consumer behavior commonly applied.B2C eCommerce, empirical evidence, success factors, endogenous sunk costs, market structure

Quantum breathing dynamics of ultracold bosons in 1D-harmonic traps: Unraveling the pathway from few- to many-body systems

Following a `bottom-up approach' in understanding many-particle effects and dynamics we provide a systematic ab initio study of the dependence of the breathing dynamics of ultracold bosons in a 1D harmonic trap on the number of bosons ranging from few to many. To this end, we employ the Multi-Layer Multi-Configuration Time-Dependent Hartree method for Bosons (ML-MCTDHB) which has been developed very recently [S. Kr\"onke, L. Cao, O. Vendrell and P. Schmelcher. {\it New J. Phys.} {\bf 15}, 063018 (2013)]. The beating behavior for two bosons is found numerically and consequently explained by an analytical approach. Drawing on this, we show how to compute the complete breathing mode spectrum in this case. We examine how the two-mode breathing behavior of two bosons evolves to the single-frequency behavior of the many-particle limit when adding more particles. In the limit of many particles, we numerically study the dependence of the breathing mode frequency on both the interaction strength as well as on the particle number. We provide an estimate for the parameter region in which Gross-Pitaevskii theory is well applicable

The use of supply chains and supply chain management in the production of forensic maps using data from a fraud case

This paper is a case study that describes the production of 3D visualisations for forensic maps that were used in a fraud case. The production path is followed from identifying the sources of data, the acquisition of the data (Source); the creation of the various 3D visualisations (Make); and to the final report (Deliver). The various production processes are the acquisition of the data, the selection of software, data clean-up and preparation, the 3D mapping, and the writing of the report based on the analysis. The production path is based on supply chains and supply chain management using the Supply-Chain Operations Reference (SCOR) model as a guideline. Three distinct periods of interest to the investigation were identified and mapped. The aim of the paper is to illustrate the use of supply chains and supply chain management to guide the production of maps. Supply chain management can be used for any type of project whether small or very large and complex.http://www.sajg.org.za/index.php/sajgam2017Geography, Geoinformatics and Meteorolog

The international repercussions of EC agricultural policy

The importance of the EC in international agricultural markets has grown steadily since the establishment of the Community and will receive another boost following its southward enlargement. Nevertheless, agricultural policy has been inward-looking and has paid, little heed to the external effects it engenders. Prof. Schmitz shows that EC agricultural policy has tended to depress world market prices, has increased their volatility and artificially distorted the price structure in the world market
