Estrategias y ventajas competitivas de los hoteles españoles y su relación con el desempeño

Actualmente, el sector hotelero está inmerso en un entorno de alta incertidumbre y muy competitivo por lo que necesita información estratégica para la correcta gestión de sus establecimientos. Dicha información puede obtenerse a partir de la clasificación de los hoteles en grupos estratégicos. Esta investigación empírica presenta los grupos estratégicos en el sector hotelero como una herramienta muy útil para la planificación y la implantación de estrategias de los hoteles ya que permiten identificar las estrategias y las ventajas competitivas de este sector. Además, se analiza si existen diferencias de desempeño entre los distintos grupos estratégicos hoteleros obtenidos. Para la identificación y la caracterización de los grupos se emplean las dimensiones compromiso de recursos y alcance de las actividades hoteleras.

Storage of classical information in quantum spins

Digital magnetic recording is based on the storage of a bit of information in the orientation of a magnetic system with two stable ground states. Here we address two fundamental problems that arise when this is done on a quantized spin: quantum spin tunneling and backaction of the readout process. We show that fundamental differences exist between integer and semi-integer spins when it comes to both reading and recording classical information in a quantized spin. Our findings imply fundamental limits to the miniaturization of magnetic bits and are relevant to recent experiments where a spin-polarized scanning tunneling microscope reads and records a classical bit in the spin orientation of a single magnetic atom.

Information systems outsourcing satisfaction: some explanatory factors

Purpose – The purpose of this paper is to analyse Information Systems outsourcing success, measuring the latter according to the satisfaction level achieved by users and taking into account three success factors: the role played by the client firm’s top management; the relationships between client and provider; and the degree of outsourcing. Design/methodology/approach – A survey was carried out by means of a questionnaire answered by 398 large Spanish firms. Its results were examined using the partial least squares software and through the proposal of a structural equation model. Findings – The conclusions reveal that the perceived benefits play a mediating role in outsourcing satisfaction and also that these benefits can be grouped together into three categories: strategic; economic; and technological ones. Originality/value – The study identifies how some success factors will be more influent than others depending which type of benefits are ultimately sought with outsourcing.
