Las percepciones del clima escolar por directivos, docentes y alumnado mediante el empleo de «redes semánticas naturales». Su importancia en la gestión de los centros educativos
Given the high indicators of various reported investigations with regard to stress and teacher illness, and acknowledging the official indicators that position the teaching profession as a profession of risk to the mental health, the present investigation assumes the objectives to investigate into the perceptions of the current state of the educational climate, and into the elements constituting obstacles of the same in changes times. Methodologically the investigation, at the phase which is described in this article, possesses a qualitative-quantitative design, with the use of 'natural semantic networks' in 189 subjects of establishments of several educational institutions from Temuco (Chile). Among the results we found that teachers and directors preponderantly relate the educational climate with interpersonal relations in the center, while students relate it exclusively to the learning contexts. Subsequently we found revealing findings between those obstacles of the educational climate, where an institutional level of the actors showed an evidence of greater semantic weight of the communication problems and the leadership style. Also, they recognized elements such as envy, intolerance, selfishness, rumors, irresponsibility, as obstacles of the person itself, elements related as much to the person of the teacher as well as the professional role. This evidences that when the educational climate is intervened these two dimensions must be addressed, without forgetting other aspects linked to the tension areas, especially the characteristics of the dynamic relationship among colleagues.Dados los altos índices que diversas investigaciones reflejan respecto al estrés y malestar docente, y reconociendo los indicadores oficiales que posicionan a la profesión docente como una profesión de riesgo para la salud mental, la presente investigación asume el objetivo de indagar en las percepciones del estado actual del clima escolar, y en los elementos obstaculizadores de éste, en tiempos de cambios complejos como los que estamos viviendo. Metodológicamente la investigación, en la fase que se describe en este artículo, posee un diseño cualitativo-cuantitativo, con empleo de «redes semánticas naturales» en 189 sujetos pertenecientes a instituciones educativas, tanto públicas (municipales), como concertadas (subvencionadas) y privadas (particulares), de la ciudad de Temuco (Chile). Entre los resultados más destacados, hemos constatado que docentes y directivos vinculan el clima escolar, mayoritariamente, a las relaciones interpersonales que tienen lugar en el centro, mientras que los alumnos y alumnas lo vinculan exclusivamente a los contextos de aprendizaje. También hemos encontrado hallazgos reveladores entre los obstaculizadores del clima escolar. En este sentido, en el ámbito institucional, los actores evidencian con mayor peso semántico los problemas de comunicación y el estilo de liderazgo ejercido. Igualmente, reconocen como obstaculizadores propios de la persona, aspectos como la envidia, la intolerancia, el egoísmo, los rumores y la irresponsabilidad, elementos que se vinculan tanto a la persona del docente, como a su rol profesional. Esto nos hace considerar que para mejorar el clima escolar debemos atender a estas dos dimensiones, sin olvidar los demás aspectos vinculados a los focos de tensión, especialmente las características de la dinámica relacional entre colegas

A dramatic isotope effect in the reaction of ClSiH with trimethylsilane-1-d: experimental evidence for intermediate complexes in silylene Si-H(D) insertion reactions
A kinetic isotope effect (kD/kH) of 7.4 has been found for the reaction of chlorosilylene with trimethysilane (Me3SiD vs Me3SiH). Such a value can be accounted for by theoretical modelling, but only if an internal rearrangement of the initially form complex is included in the mechanism. This provides the first concrete evidence for such complexes
Mars and the ESA Science Programme - the case for Mars polar science
Current plans within the European Space Agency (ESA) for the future investigation of Mars (after the ExoMars programme) are centred around participation in the Mars Sample Return (MSR) programme led by NASA. This programme is housed within the Human and Robotic Exploration (HRE) Directorate of ESA. This White Paper, in response to the Voyage 2050 call, focuses on the important scientific objectives for the investigation of Mars outside the present HRE planning. The achievement of these objectives by Science Directorate missions is entirely consistent with ESA’s Science Programme. We illustrate this with a theme centred around the study of the Martian polar caps and the investigation of recent (Amazonian) climate change produced by known oscillations in Mars’ orbital parameters. Deciphering the record of climate contained within the polar caps would allow us to learn about the climatic evolution of another planet over the past few to hundreds of millions of years, and also addresses the more general goal of investigating volatile-related dynamic processes in the Solar System
Climate Change & Tourism Literature Review
Climate change and global warming have become hot topics of research over the past decade. Tourism is intimately a part of the climate change issue. The purpose of this literature review was to identify and understand where, how much, and what type of topics related to climate change and tourism currently exist in the literature
Influence of Congruity in Store-Attribute Dimensions and Self-Image on Purchase Intentions in Online Stores of Multichannel Retailers
Online stores of multichannel retailers continue to lag pure internet retailers with reference to consumers\u27 shopping intentions and sales. This study develops and tests a framework in which (a) trust and attitude (conceptualized as a second-order construct with hedonic and utilitarian dimensions) influence purchase intentions, (b) congruity between the multichannel retailer\u27s land-based and online stores (conceptualized as a second-order constructs made up of seven dimensions: aesthetic appeal, navigation convenience, transaction convenience, atmosphere, service, price orientation, and security) influences trust in and attitude toward the online store, and (c) congruity between consumers\u27 self-image and perceived image of the online store influences trust in and attitude toward the online store. The findings provide robust support for the framework and have strong implications for theory and practice
Optimización integral del centro de mantenimiento de intendencia
Las exigencias de la vida moderna, obligan a las instituciones públicas y privadas, a involucrarse en los avances y desarrollos tecnológicos, a fin de alcanzar un alto rendimiento en su producto o servicio que les permita el ingreso a nuevos mercados locales e internacionales, los cuales se vuelven cada vez más exigentes y competitivos. La Globalización, los cambios vertiginosos en los cuales se desenvuelve las organizaciones, son tan rápidos que han inducido a que instituciones como Fuerzas Armadas, y dentro de esta a la industria metalmecánica, opten por un cambio de filosofía en su cultura organizacional, en donde no existe otra alternativa que aprender a competir y buscar nuevas oportunidades para mejorar su potencial operativo tanto interno como externo en busca de un constante crecimiento y desarrollo institucional

Aiding Fair Trade Online Through Place Branding
With the increased awareness of developed nations about social inequities in the world, fair trade has become in vogue. The Internet provides an opportunity for fair trade organizations (FTOs) to market their goods and take advantage of the desire of customers in developed nations to pay greater than free trade prices to reduce social inequities. FTOs, however, lack resources and knowledge to compete online against established retailers and/or branded products. We argue that through place branding FTOs can maximize their Internet retailing presence and expand their reach while increasing awareness of ethical consumerism. Free trade and place branding are reviewed and suggestions for the adoption of place branding online are discussed
Generation of two-photon EPR and Wstates
In this paper we present a scheme for generation of two-photon EPR and W
states in the cavity QED context. The scheme requires only one three-level
Rydberg atom and two or three cavities. The atom is sent to interact with
cavities previously prepared in vacuum states, via two-photon process. An
appropriate choice of the interaction times one obtains the mentioned state
with maximized fidelities. These specific times and the values of success
probability and fidelity are discussed.Comment: 4 pages, 5 figure
