Social responsibility act against the manager and itsrelationship with the butterfly effect

Este trabajo tiene por objeto identificar la actuación del Gerente, frente a la responsabilidad social en su labor diaria dentro de las organizaciones; relacionando el efecto mariposa y las consecuencias que este puede ocasionar en el quehacer de la dirección, generando resultados positivos o negativos en el desarrollo organizacional. El principal aporte del trabajo es dejar la reflexión profesional del actuar; conformado por los apartes de Responsabilidad social y efecto mariposa.This work aims to identify the performance of the Manager, versus social responsibility in their daily work within organizations; relating the butterfly effect and the consequences that this may result in the work of leadership, generating positive or negative results in the organizational development. The main contribution of this paper is to let professional reflection act, made up of excerpts of Social Responsibility and the butterfly effect

Magnetothermal Conductivity of Highly Oriented Pyrolytic Graphite in the Quantum Limit

We report on the magnetic field (0T$\le B \le 9$T) dependence of the longitudinal thermal conductivity $\kappa(T,B)$ of highly oriented pyrolytic graphite in the temperature range 5 K $\le T\le$ 20 K for fields parallel to the $c-$axis. We show that $\kappa(T,B)$ shows large oscillations in the high-field region (B > 2 T) where clear signs of the Quantum-Hall effect are observed in the Hall resistance. With the measured longitudinal electrical resistivity we show that the Wiedemann-Franz law is violated in the high-field regime.Comment: 4 Figures, to be published in Physical Review B (2003

Micromecanizado Láser de Componentes de Gran calidad de Acabado Superficial

El uso de láseres pulsados con anchos temporales de nanosegundos y longitudes de onda en el rango Ultravioleta, permiten un preciso control del material abferido, convirtiendo dicha técnica en una herramienta fundamental para mecanizados que requieren de una gran calidad y acabado, con relaciones de aspecto muy altas. Este trabajo presenta un análisis paramétrico de la influencia de las distintas variables de proceso para diferentes tipos de materiales (metálicos, dieléctricos, materiales orgánicos, etc) en la calidad y acabado final. The use of nanoseconds U.V. lasers permits a precise control in ablation’s processes. As a result this tool plays a fundamental role in machining where a high quality and good aspect ratios are required. This paper presents a parametric analysis of the influence of some processing parameters for different types of materials

Integer Quantum Hall Effect in Graphite

We present Hall effect measurements on highly oriented pyrolytic graphite that indicate the occurrence of the integer quantum-Hall-effect. The evidence is given by the observation of regular plateau-like structures in the field dependence of the transverse conductivity obtained in van der Pauw configuration. Measurements with the Corbino-disk configuration support this result and indicate that the quasi-linear and non-saturating longitudinal magnetoresistance in graphite is governed by the Hall effect in agreement with a recent theoretical model for disordered semiconductors.Comment: 3 figures, to be published in Solid State Communication (2006

Introduced marine macroflora of Lebanon and its distribution on the Levantine coast

The marine macroflora introduced into Lebanon was studied through an analysis of historical data and field studies carried out since 1991. A total of 29 introduced species have been listed: 3 Chromobionta, 13 Rhodobionta, 12 Chlorobionta and 1 Streptobionta. Among them, Caulerpa taxifolia var. distichophylla, Spatoglossum variabile and Womersleyella setacea are recorded for the first time from Lebanon. Among them, Asparagopsis taxiformis, C. taxifolia var. distichophylla, Cladophora patentiramea, Codium arabicum, Codium parvulum, Galaxaura rugosa, Halophila stipulacea, Hypnea cornuta, Laurencia cf. chondrioides, Lophocladia lallemandii, Stypopodium schimperi, Ulva lactuca and Womersleyella setacea are potentially invasive species, and several of them already occupy extensive stretches of the Lebanese coast. The distribution of species on the Levantine coast, their dynamics and the current status of their populations are discussed.The surveys in 2012, 2013 and 2016 were conducted within the framework of the MedMPAnet Project, implemented by UNEP/MAP-RAC/SPA and funded by RAC/SPA, the European Commission (EC), the Spanish Agency for International Cooperation for Development (AECID), and the French Global Environment Facility (FFEM)

Social deprivation and exposure to health promotion. A study of the distribution of health promotion resources to schools in England

This article has been made available through the Brunel Open Access Publishing Fund and is available from the specified link - Copyright @ 2010 Chivu and ReidpathBACKGROUND: Area deprivation is a known determinant of health. It is also known that area deprivation is associated with lower impact health promotion. It is less well known, however, whether deprived areas are less responsive to health promotion, or whether they are less exposed. Using data from a national, school-based campaign to promote vaccination against the human papilloma virus (HPV), the relationship between area deprivation and exposure was examined. METHODS: Taking advantage of a health promotion campaign to provide information to schools about HPV vaccination, a cross sectional study was conducted to examine the relationship between area level, social deprivation, and take-up of (i.e., exposure to) available health promotion material. The sample was 4,750 schools across England, including government maintained and independent schools. The relationship between area deprivation and exposure was examined using bi- and multivariate logistic regression. RESULTS: It was found that schools in the least deprived quintile had 1.32 times the odds of requesting health promotion materials than schools in the most deprived areas (p = .01). This effect was independent of the school size, the type of school, and the geographic region. Conclusion The relationship between area deprivation and the impact of health promotion may be due, at least in part, to differential levels of exposure. The study was limited in scope, pointing to the need for more research, but also points to potentially important policy implications
