Training plans, manager’s characteristics and innovation in the accommodation industry.

This paper explores the effect of training plans and managerial characteristics on innovation activity in the hospitality sector. This sector is featured by being labor-intensive so the examination of employment and managers skills deserves attention in order to determine the level of quality and competitive advantage in the provision of services. The data in the paper comes from a questionnaire administered to hotel managers in a representative sample of hotels in the Balearic Islands, a leading tourist destination. Results suggest that training plans positively affect innovation-related decisions and the extent of their implementation; however, managers should have more than experience to manage the innovation change, specifically skills and capabilitiesInnovación; Hoteles; Formación;

Lagrangian transport in a microtidal coastal area: the Bay of Palma, island of Mallorca, Spain

Coastal transport in the Bay of Palma, a small region in the island of Mallorca, Spain, is characterized in terms of Lagrangian descriptors. The data sets used for this study are the output for two months (one in autumn and one in summer) of a high resolution numerical model, ROMS, forced atmospherically and with a spatial resolution of 300 m. The two months were selected because its different wind regime, which is the main driver of the sea dynamics in this area. Finite-size Lyapunov Exponents (FSLEs) were used to locate semi-persistent Lagrangian coherent structures (LCS) and to understand the different flow regimes in the Bay. The different wind directions and regularity in the two months have a clear impact on the surface Bay dynamics, whereas only topographic features appear clearly in the bottom structures. The fluid interchange between the Bay and the open ocean was tudied by computing particle trajectories and Residence Times (RT) maps. The escape rate of particles out of the Bay is qualitatively different, with a 32$$ more of escape rate of particles to the ocean in October than in July, owing to the different geometric characteristics of the flow. We show that LCSs separate regions with different transport properties by displaying spatial distributions of residence times on synoptic Lagrangian maps together with the location of the LCSs. Correlations between the time-dependent behavior of FSLE and RT are also investigated, showing a negative dependence when the stirring characterized by FSLE values moves particles in the direction of escape

La intervención de Q. Cecilio Metelo sobre las Baleares (123 a 121 a. C.). Condiciones previas y sus consecuencias

En este artículo se tienen en cuenta, a la hora de valorar el proceso de romanización de las Baleares, las culturas prerromanas, la talayótica en Mallorca y Menorca, y la púnica en las Pitiusas. Se analizan las circunstancias de la República Romana en el momento de tomar la decisión de intervenir militarmente sobre las Baleares. En este trabajo se entrelazan los datos procedentes de las fuentes literarias con los arqueológicos, mediante una interpretación de ese pasado, que lleva a plantear que el mayor interés de Roma sobre estas islas fue ponerlas bajo su órbita para asegurar la ruta marítima entre la Península Itálica y la Ibérica.This article presents the pre-Roman cultures prevailing in Mallorca and Menorca, Talayotic on the one hand and that of the Pitiusas islands on the other, Punic. It then sets out the circumstances of the Roman Republic leading to the decision to conquer the islands. It next analyses the response of the different cultures to the effects of Romanization. The work connects literary sources and archaeological evidence to interpret these events, showing that the primary reason for the conquest was the need for the maritime routes, and to obtain slings for war. It concludes by explaining the long term effect of the conquest on the two cultures

Private Multi-party Matrix Multiplication and Trust Computations

This paper deals with distributed matrix multiplication. Each player owns only one row of both matrices and wishes to learn about one distinct row of the product matrix, without revealing its input to the other players. We first improve on a weighted average protocol, in order to securely compute a dot-product with a quadratic volume of communications and linear number of rounds. We also propose a protocol with five communication rounds, using a Paillier-like underlying homomorphic public key cryptosystem, which is secure in the semi-honest model or secure with high probability in the malicious adversary model. Using ProVerif, a cryptographic protocol verification tool, we are able to check the security of the protocol and provide a countermeasure for each attack found by the tool. We also give a randomization method to avoid collusion attacks. As an application, we show that this protocol enables a distributed and secure evaluation of trust relationships in a network, for a large class of trust evaluation schemes.Comment: Pierangela Samarati.
