Projecting biodiversity and wood production in future forest landscapes: 15 key modeling considerations
2017
A variety of modeling approaches can be used to project the future development of forest systems, and help to assess the implications of different management alternatives for biodiversity and ecosystem services. This diversity of approaches does however present both an opportunity and an obstacle for those trying to decide which modeling technique to apply, and interpreting the management implications of model output. Furthermore, the breadth of issues relevant to addressing key questions related to forest ecology, conservation biology, silviculture, economics, requires insights stemming from a number of distinct scientific disciplines. As forest planners, conservation ecologists, ecologica…
Estudio de la variabilidad genética de repoblaciones de Quercus ilex L. subsp. ballota (Desf.) Samp. in Bol. en Andalucìa
2005
An adequate management of the reproductive material for reforestation activities is fundamental in the conservation of forest genetic resources. In the present work the levels of genetic diversity and differentiation between artificial stands of Quercus ilex and the adjacent natural stands are assessed with nuclear microsatellites. Also, it was possible to analyse the natural population used as seed source for one of the reforestations studied. The levels of genetic differentiation between natural and artificial stands and the decrease of genetic diversity from the seed origin population to the reforestation are discussed in relation to the transference of seed among provenance regions and …
Protection of Trees against Lightning Strikes as a Measure to Prevent Fires and Loss of Human Life
2021
Lighting strikes have been the catalyst of massive uncontrolled fires in areas of combustible vegetation. In some regions, lightning strikes may be a relatively unusual occurrence (e.g., California), but instead they seem to have become a major contributor to the propagation of wildfires, as a byproduct of climate change. Given such unusual weather, wildfires originating from lightning are an increasing threat. In this paper, the authors discuss the withstand capability of trees against lightning and introduce a proactive approach to prevent wildfires by the deployment of tree lighting protection systems (TLPS) to protect forested areas, where deemed necessary by the tree risk assessment.
RED. Revista de educación a distancia
2021
El mundo requiere personas con conocimientos, habilidades y actitudes que permitan un desarrollo completo de la ciudadanía en un ecosistema digital. Una respuesta educativa a esta exigencia social es la competencia digital. Así, esta finalidad exige niveles óptimos de desarrollo de la Competencia Digital Docente (CDD), en especial en el sector de la Formación Profesional (FP). Con la idea de atender este contexto educativo, en este trabajo se propone un marco de comprensión que integra de forma unitaria la visión sobre la pedagogía, los recursos y la evaluación para entender, evaluar y proponer mejoras en la competencia digital del profesorado de FP. Empleando un enfoque cualitativo, se rea…
Los centros de formación y educación profesional: una alternativa para el desarrollo local.
2014
Este artículo presenta una propuesta educativa de índole técnico pero con bases enraizadas en la educación popular (Freire, 1970). La misma pretende dar luces de cómo la educación profesional podría tener una vinculación para el desarrollo local del territorio. El desarrollo local tiene sus máximos exponentes en los ámbitos de la recuperación de las fuentes endógenas y en la articulación del tejido asociativo (Herrera, 2009), con el consecuente beneficio de la potenciación de instrumentos participativos que mejoren los intercambios democráticos del territorio. Los centros educativos pueden tener una visión privilegiada del territorio, ya que confluyen en el mismo algunos elementos, actores …
The quality of life in the Finnish game industry
2013
Tässä tutkimuksessa tutkitaan työntekijöiden elämänlaatua Suomen peliteollisuudessa. Tutkimus perustuu International Game Developers Associationin (IGDA) vastaavanlaiseen tutkimukseen, joka toteutettiin huhtikuussa 2004. Tavoitteena on tarkastella ongelmia, jotka ovat nähtävissä peliyritysten työympäristössä. Päätavoitteena tässä laadullisessa tapaustutkimuksessa oli selvittää, mitkä ovat yleisiä elämänlaatuun liittyviä ongelmia pelinkehitysyrityksissä ja mitkä olisivat parhaat käytännöt ehkäisemään tai vähentämään elämänlaatuun liittyviä ongelmia. Tutkimuksen tulokset osoittavat, että suomalaisella pelialalla on tällä hetkellä pula osaavista työntekijöistä. Vaikka peliteollisuus on nopeast…
Theoretical Game Approach for Mobile Users Resource Management in a Vehicular Fog Computing Environment
2018
Vehicular Cloud Computing (VCC) is envisioned as a promising approach to increase computation capabilities of vehicle devices for emerging resource-hungry mobile applications. In this paper, we introduce the new concept of Vehicular Fog Computing (VFC). The Fog Computing (FC) paradigm evolved and is employed to enhance the quality of cloud computing services by extending it to the edge of the network using one or more collaborative end-user clients or near-user edge devices. The VFC is similar to the VCC concept but uses vehicles resources located at the edge of the network in order to serve only local on-demand mobile applications. The aim of this paper is to resolve the problem of admissi…
Fuzzy logic controller and game theory based distributed energy resources allocation
2020
Energy management and demand control through conventional energy generation sources are challenging for energy providers. Distributed energy resources (DERs) allocation near load centers may provide a suitable solution. The main contribution of the paper improves the voltage profile and reduce the active and reactive power losses in the distribution network. DERs are integrated with IEEE 33 bus system using fuzzy logic controller (FLC) and game theory for two different cases with unity and 0.9 power factor (PF) and compares with conventional methods of integration (i.e., modified novel method, power loss sensitivity method, voltage sensitivity analysis method). The capacity of DERs is optim…
A game theoretic approach to MAC design for infrastructure networks
2010
Wireless network operation intrinsically assumes different forms of cooperation among the network nodes, such as sharing a common wireless medium without interfering, relaying frames belonging to other nodes, controlling the transmission power for optimizing spectrum reuse, coding cooperatively multiple frames for improving information redundancy, and so on. For this reason, Game Theory has been extensively employed to model wireless networks. In particular, we propose a game-theoretic approach for defining a generalized medium access protocol for slotted contention-based channels. Contention-based channels are largely adopted in data networks, e.g. in WiFi and WiMax networks and in some em…
Paroles de chef : modèles communicationnels d’une organisation professionnelle
2016
Dans un restaurant, communiquer correspond à informer la clientèle, dialoguer avec elle, collaborer avec les équipes, et diffuser une image du restaurant, des mets et du chef. La communication apparente du chef de cuisine précise le lien qui existe entre lui et son personnel, lui et les clients, lui et les fournisseurs, et plus rarement entre lui et les médias ou supports de communication. Apportant la communication organisationnelle, formelle et normative, auprès de ses subalternes comme de ses fournisseurs, le chef cuisinier tente de diffuser une communication mi-naturelle afin de parfaire une certaine convivialité, et mi-formelle afin de transmettre ou confirmer son savoir-faire. Il s’ag…
