This study examines the relevance of environmental management as a source of competitive advantage for hotels. The relationship between the environmental proactivity of hotels located in the province of Alicante (Spain) and their economic performance levels was studied, and three…

Purpose – This study has a twofold purpose: to identify the competitive strategies and advantages of hotels located in the province of Alicante (Spain); and to inform hotel managers about how some key strategic variables (size, type of hotel management,…

The harmonic balance method is used to construct approximate frequency–amplitude relations and periodic solutions to the relativistic oscillator. By combining linearization of the governing equation with the harmonic balance method, we construct analytical approximations to the oscillation frequencies and periodic…

In this paper we present our software framework for robotic applications, jde-neoc. This is the second implementation of our cognitive behavior-based architecture JDE, and it is aimed to overcome some of the limitations observed in three years using the first…

In this work we present a reactive autonomous robot navigation system based only on omnidirectional vision. It does not rely on any prior knowledge about the environment apart from assuming a structured one, like indoor corridors or outdoor avenues. The…

The research presented in this paper approaches the issue of indoor localization using the fuzzy logic framework for modeling and dealing with the uncertainty of the position measurements. Fuzzy logic presents properties that make it suitable tool to represent and…

Background: Perpetrators’ experiences of violence during childhood are considered a risk factor for intimate partner violence (IPV). The objective of this study is to systematically review the characteristics and quality of papers which analyse the association between being battered during…

Angiotensin II (Ang II) highly stimulates superoxide anion production by neutrophils. The G-protein Rac2 modulates the activity of NADPH oxidase in response to various stimuli. Here, we describe that Ang II induced both Rac2 translocation from the cytosol to the…

Purpose – Faced with increasing environmental problems, traditional methods for transmitting information regarding corporate environmental actions are insufficient. Accordingly, the purpose of this paper is to suggest the environmental capital report, the knowledge map and the balanced scorecard as alternative…

Although radix 10 based arithmetic has been gaining renewed importance over the last few years, decimal systems are not efficient enough and techniques are still under development. In this paper, an improvement of the CORDIC (coordinate rotation digital computer) method…
