Strategic and tactical price decisions in hotel revenue management

Dynamic pricing techniques allow using a number of variables in a tactical way compared to standard catalogue prices. This study merges in a conceptual model the relevance of the tactical and the strategic dimension of these variables, classified according to their tangible, reputational or contextual nature. To empirically validate the hypotheses, a database of 21.596 price observations was retrieved from booking.com. The study presents a hedonic price function, using the Shapley-Owen decomposition of the Rsquared to elicit the importance of each group of factors. Further, a hierarchical cluster analysis measures the presence of heterogeneity across operators. The results show that online reputation is gaining importance over the traditional star rating. Despite the tangible variables remain of paramount importance, the findings suggest the relevant role of contextual variables in short-run price variations. The players operating in the tourism and hospitality industries should integrate these findings when designing pricing strategies

Up to 4 × 192 LTE-A radio waveforms transmission in a point to multipoint architecture for massive fronthauling solutions

In this work, a novel point-to-multipoint fronthauling architecture based on the use of a Multi-Output Erbium Doped Fibre Amplifier (MO-EDFA), to deliver several digital signal processing (DSP) aggregated analogue radio waveforms, is proposed and experimentally analysed. The transmission of 4x192 20 MHz radio waveforms, according to the DSP-aggregated fronthauling (DSP-AF) Frequency Division Multiplexed (FDM) architecture originally proposed in [1]. Using the MO-EDFA, we are able to feed up to 24 remote radio head (RRH) units, experimentally demonstrating successful transmission over a link with up to 25 dB of optical path losses, including 37 km of single mode fibre

Rate coefficient and mechanism of the OH-Initiateddegradation of 1-chlorobutane: atmospheric implications

In this work, we investigate the degradation process of 1-chlorobutane, initiated by OH radicals, under atmospheric conditions (air pressure of 750 Torr and 296 K) from both experimental and theoretical approaches. In the first one, a relative kinetic method was used to obtain the rate coefficient for this reaction, while the products were identified for the first time (1-chloro-2-butanone, 1-chloro-2-butanol, 4-chloro-2-butanone, 3-hydroxy-butanaldehyde, and 3-chloro-2-butanol) using mass spectrometry, allowing suggesting a reaction mechanism. The theoretical calculations, for the reactive process, were computed using the BHandHLYP/6-311++G(d,p) level of theory, and the energies for all of the stationary points were refined at the CCSD(T) level. Five conformers for 1-chlorobutane and 33 reactive channels with OH radicals were found, which were considered to calculate the thermal rate coefficient (as the sum of the site-specific rate coefficients using canonical transition state theory). The theoretical rate coefficient (1.8 × 10-12 cm3 molecule-1 s-1) is in good agreement with the experimental value (2.22 ± 0.50) × 10-12 cm3 molecule-1 s-1 determined in this work. Finally, environmental impact indexes were calculated and a discussion on the atmospheric implications due to the emissions of this compound into the troposphere was given.Fil: Jara Toro, Rafael Alejandro.
