Balanced scorecard to improve strategic management control at School of Mines and Energy, Universidad Politécnica de Madrid

We studied the situation in Spanish public universities regarding the use of the Balanced Scorecard (BSC), as an instrument of control and strategic management. Also, we studied its application to the School of Mines and Energy at Universidad Politécnica de Madrid. The main advantage of the BSC is that improves the organizational structure of the workplace and the achievement of the objectives that ensure long-term success. First we review the strategy for success used in the Spanish educational system and specifically in the Spanish public universities. Then using the BSC and applying the main strategic lines for the successful management of the School of Mines and Energy at Universidad Politécnica de Madrid. The strategic lines affect all the college groups and the success of the BSC tool is to increase communication between the faculties, personal auxiliary, students and society in general that make up the university. First we performed a SWOT analysis (DAFO in Spanish) there are proposed different perspectives that focus the long-term strategic objectives. The BSC is designed based on the strategic objectives that set the direction through using indicators and initiatives, the goals are achieved up to the programmed schedule. In the perspective of teaching, objectives are set to update facilities and increase partnerships with other universities and businesses, encouraging ongoing training of staff and improved coordination and internal communication. The internal process perspective aims at improving the marketing, the promotion of the international dimension of the school through strategic alliances, better mobility for students and professors and improved teaching and research quality results. It continues with improving the image of the school between customer?s perspective, the quality perceived by students and the loyalty of the teaching staff by retaining talent. Finally, the financial perspective which should contain costs without harming the quality, improving the employability of students and achieve relevant jobs at teaching and research through international measurement standards.

Enhancing K-12 science education through a multi-device web tool to facilitate content integration and e-infrastructure access

An effective K-12 science education is essential to succeed in future phases of the curriculum and the e-Infrastructures for education provide new opportunities to enhance it. This paper presents ViSH Viewer, an innovative web tool to consume educational content which aims to facilitate e-Science infrastructures access through a next generation learning object called "Virtual Excursion". Virtual Excursions provide a new way to explore science in class by taking advantage of e-Infrastructure resources and their integration with other educational contents, resulting in the creation of a reusable, interoperable and granular learning object. In order to better understand how this tool can allow teachers and students a joyful exploration of e-Science, we also present three Virtual Excursion examples. Details about the design, development and the tool itself are explained in this paper as well as the concept, structure and metadata of the new learning object.

The water footprint of a river basin with a special focus on groundwater: The case of Guadalquivir basin (Spain).

In addition to revealing the hidden link between products or consumption patterns of populations and their needs in terms of water resources, the water footprint (WF) indicator generates new debates and solutions on water management at basin scale. This paper analyses the green and blue WF of the Guadalquivir basin and its integration with environmental water consumption, with a special emphasis on the WF from groundwater and its consequences on current and future depletion of surface water. In a normal year, green WF (agriculture and pastures) amounts to 190 mm on a total green water consumption of 410 mm, while the blue WF (50 mm) represents half of the total blue water flows. This constitutes a first overview and alternative interpretations of the WF as human water appropriation are introduced. The blue WF is almost entirely associated to agriculture (40 mm). The presentation of its evolution over the period 1997?2008 reveals the rising WF from groundwater (13 mm in 2008), 86% being current consumption of surface flows. This evolution is particularly ascribed to the recent development of irrigated olive groves from groundwater. To prevent a higher pressure on the environment, this new use, like all others (thermo-solar plants, tourism, etc.), could have been obtained from the reallocation of water from crops with low water productivity. It means that water is not lacking in the Guadalquivir basin if the governance setting integrates more flexibility and equity in the allocation of water to address climatic variability and the emergence of new demands.

Integration of congestion pricing and intertemporal preferences rate integration in social welfare function

Many researchers have used theoretical or empirical measures to assess social benefits in transport policy implementation. However, few have measured social benefits by using discount rates, including the intertemporal preference rate of users, the private investment discount rate, and the intertemporal preference rate of the government. In general, the social discount rate used is the same for all social actors. This paper aims to assess a new method by integrating different types of discount rates belonging to different social actors to measure the real benefits of each actor in the short term, medium term, and long term. A dynamic simulation is provided by a strategic land use and transport interaction model. The method was tested by optimizing a cordon toll scheme in Madrid, Spain. Socioeconomic efficiency and environmental criteria were considered. On the basis of the modified social welfare function, the effects on the measure of social benefits were estimated and compared with the classical welfare function measures. The results show that the use of more suitable discount rates for each social actor had an effect on the selection and definition of optimal strategy of congestion pricing. The usefulness of the measure of congestion toll declines more quickly over time. This result could be the key to understanding the relationship between transport system policies and the distribution of social actors? benefits in a metropolitan context.

Integrated studies for the evaluation of conservation treatments on buildings materials from archaeological sites: application to the case of Merida (Spain)

The application of conservation treatments, such as consolidation and protection ones, has been demonstrated ineffective in many cases, and even harmful. Evaluation studies should be a mandatory task, ideally before and after the intervention, but both tasks are complex and unusual in the case of archaeological heritage. This study is mainly focused on analyzing changes in petrophysical properties of stone material from archaeological sites of Merida (Spain), evaluating, both on site and in laboratory, effects derived from different conservation treatments applied in past interventions, throughout the integration of different non-destructive techniques (NDT) and portable devices of analysis available at the Institute of Geosciences (CSIC,UCM). These techniques allow, not only assessment of effectiveness and alteration processes, but also monitoring durability of treatments, focused mainly on 1996 intervention in the case of Roman Theater, as well as different punctual interventions from the 90?s until date in the House of Mitreo. Studies carried out on archaeological sites of Merida permit us to compare outcomes and also check limitations in the use of those equipments. In this paper we discuss about the use of some techniques, their integration and limits, for the assessment of conservation treatments, showing some examples of Merida?s case study.

First steps of Roman Cement in Spain

Natural cement was patented in 1796 but it didn’t arrive in Spain until 1835. No one knows exactly where the production started in Spain, because it emerged independently at the same time in many places. Most of these outbreaks are concentrated in the north and northwest of Spain: Basque Country (Zumaya and Rezola) and Catalonia (San Celoní and San Juan de las Abadesas).Natural cement was extensively used to decorate historical buildings during the nineteenth and beginning of twentieth century in Madrid. It was the building material which realised the architects and builders dreams of mass-produced cast elements in a wide variety of styles. Its arrival replaced traditional materials that were used previously (lime, gypsum and hydraulic limes). However, its use was not extended in time, and soon it was replaced by the use of artificial Portland cements. During 20th century this building material disappeared from use. What remains is it’s memory, in thousands and thousands of “stone witnesses” in our cities. Final properties of the cement largely depend on raw materials used and its combustion temperature. However, it was characterised by an easily implementation on facade masonry, fast-setting (about 15 minutes), good resistance , an agreeable structural consistency and colour.This article aims to show first steps, evolution and decay of Natural Cement Industry in Spain and its application in Madrid.

COST Action Urban Agriculture Europe Training School «Urban agriculture inside the city:alternatives for vacant lots and public space»

The third Training School of the Action took place in Vitoria-Gasteiz (Basque country, Spain) from 24th to 26th September 2014. Vitoria-Gateiz has experimented an important urban outgrowth in the last decade, mainly through the planning and development of two new neighborhoods, Zabalgana and Salburúa, situated at the eastern and western border of the city, by the Greenbelt. These new development are well-equipped and designed according to sustainability principles. Nevertheless, among the main problems they present is their over-dimensioned public space, which creates some areas lacking enough density and mix of uses. On the other hand it is very expensive for the municipality to maintain these public space with the high Vitorian urban standards for public space. The proposed solution for this problem is a strategy of "re-densification" through the insertion of new uses The debate has arisen about which are the most adequate uses to insert in order to get an increasing of urban vitality, specially considering that housing has reached its peak and that Vitoria-Gasteiz is well served with social and sport amenities. The main goal of the TS was to offer an opportunity for the reflection about how urban agriculture might be an optimal alternative for the re-qualifying of this over-dimensioned public space in the new neighbourhoods, especially considering it synergic potential as a tool for production, leisure and landscaping, including the possibility of energy crops within the limits of urban space. Continuity with rural and natural surrounding area through alternatives for urban fringe at the small scale is a relevant issue to be considered as well within the reflection. Taking Zabalgana neighbourhood as a practical field for experiment, the Training School is conceived as a practical and intensive design charrette to be held during a whole day after two days of local knowledge-deepening through field visits and presentations.

Integration of physical, chemical and biological tactics against insect pests and virus diseases in horticultural crops

Actualmente, la gestión de sistemas de Manejo Integrado de Plagas (MIP) en cultivos hortícolas tiene por objetivo priorizar los métodos de control no químicos en detrimento del consumo de plaguicidas, según recoge la directiva europea 2009/128/CE ‘Uso Sostenible de Plaguicidas’ (OJEC, 2009). El uso de agentes de biocontrol como alternativa a la aplicación de insecticidas es un elemento clave de los sistemas MIP por sus innegables ventajas ambientales que se utiliza ampliamente en nuestro país (Jacas y Urbaneja, 2008). En la región de Almería, donde se concentra el 65% de cultivo en invernadero de nuestro país (47.367 ha), MIP es la principal estrategia en pimiento (MAGRAMA, 2014), y comienza a serlo en otros cultivos como tomate o pepino. El cultivo de pepino, con 8.902 ha (MAGRAMA, 2013), tiene un protocolo semejante al pimiento (Robledo et al., 2009), donde la única especie de pulgón importante es Aphis gossypii Glover. Sin embargo, pese al continuo incremento de la superficie de cultivo agrícola bajo sistemas MIP, los daños originados por virosis siguen siendo notables. Algunos de los insectos presentes en los cultivos de hortícolas son importantes vectores de virus, como los pulgones, las moscas blancas o los trips, cuyo control resulta problemático debido a su elevada capacidad para transmitir virus vegetales incluso a una baja densidad de plaga (Holt et al., 2008; Jacas y Urbaneja, 2008). Las relaciones que se establecen entre los distintos agentes de un ecosistema son complejas y muy específicas. Se ha comprobado que, pese a que los enemigos naturales reducen de manera beneficiosa los niveles de plaga, su incorporación en los sistemas planta-insecto-virus puede desencadenar complicadas interacciones con efectos no deseables (Dicke y van Loon, 2000; Jeger et al., 2011). Así, los agentes de biocontrol también pueden inducir a que los insectos vectores modifiquen su comportamiento como respuesta al ataque y, con ello, el grado de dispersión y los patrones de distribución de las virosis que transmiten (Bailey et al., 1995; Weber et al., 1996; Hodge y Powell, 2008a; Hodge et al., 2011). Además, en ocasiones el control biológico por sí solo no es suficiente para controlar determinadas plagas (Medina et al., 2008). Entre los métodos que se pueden aplicar bajo sistemas MIP están las barreras físicas que limitan la entrada de plagas al interior de los invernaderos o interfieren con su movimiento, como pueden ser las mallas anti-insecto (Álvarez et al., 2014), las mallas fotoselectivas (Raviv y Antignus, 2004; Weintraub y Berlinger, 2004; Díaz y Fereres, 2007) y las mallas impregnadas en insecticida (Licciardi et al., 2008; Martin et al., 2014). Las mallas fotoselectivas reducen o bloquean casi por completo la transmisión de radiación UV, lo que interfiere con la visión de los insectos y dificulta o impide la localización del cultivo y su establecimiento en el mismo (Raviv y Antignus, 2004; Weintraub, 2009). Se ha comprobado cómo su uso puede controlar los pulgones y las virosis en cultivo de lechuga (Díaz et al., 2006; Legarrea et al., 2012a), así como la mosca blanca, los trips y los ácaros, y los virus que estos transmiten en otros cultivos (Costa y Robb, 1999; Antignus et al., 2001; Kumar y Poehling, 2006; Doukas y Payne, 2007a; Legarrea et al., 2010). Sin embargo, no se conoce perfectamente el modo de acción de estas barreras, puesto que existe un efecto directo sobre la plaga y otro indirecto mediado por la planta, cuya fisiología cambia al desarrollarse en ambientes con falta de radiación UV, y que podría afectar al ciclo biológico de los insectos fitófagos (Vänninen et al., 2010; Johansen et al., 2011). Del mismo modo, es necesario estudiar la compatibilidad de esta estrategia con los enemigos naturales de las plagas. Hasta la fecha, los estudios han evidenciado que los agentes de biocontrol pueden realizar su actividad bajo ambientes pobres en radiación UV (Chyzik et al., 2003; Chiel et al., 2006; Doukas y Payne, 2007b; Legarrea et al., 2012c). Otro método basado en barreras físicas son las mallas impregnadas con insecticidas, que se han usado tradicionalmente en la prevención de enfermedades humanas transmitidas por mosquitos (Martin et al., 2006). Su aplicación se ha ensayado en agricultura en ciertos cultivos al aire libre (Martin et al., 2010; Díaz et al., 2004), pero su utilidad en cultivos protegidos para prevenir la entrada de insectos vectores en invernadero todavía no ha sido investigada. Los aditivos se incorporan al tejido durante el proceso de extrusión de la fibra y se liberan lentamente actuando por contacto en el momento en que el insecto aterriza sobre la malla, con lo cual el riesgo medioambiental y para la salud humana es muy limitado. Los plaguicidas que se emplean habitualmente suelen ser piretroides (deltametrina o bifentrín), aunque también se ha ensayado dicofol (Martin et al., 2010) y alfa-cipermetrina (Martin et al., 2014). Un factor que resulta de vital importancia en este tipo de mallas es el tamaño del poro para facilitar una buena ventilación del cultivo, al tiempo que se evita la entrada de insectos de pequeño tamaño como las moscas blancas (Bethke y Paine, 1991; Muñoz et al., 1999). Asimismo, se plantea la necesidad de estudiar la compatibilidad de estas mallas con los enemigos naturales. Es por ello que en esta Tesis Doctoral se plantea la necesidad de evaluar nuevas mallas impregnadas que impidan el paso de insectos de pequeño tamaño al interior de los invernaderos, pero que a su vez mantengan un buen intercambio y circulación de aire a través del poro de la malla. Así, en la presente Tesis Doctoral, se han planteado los siguientes objetivos generales a desarrollar: 1. Estudiar el impacto de la presencia de parasitoides sobre el grado de dispersión y los patrones de distribución de pulgones y las virosis que éstos transmiten. 2. Conocer el efecto directo de ambientes pobres en radiación UV sobre el comportamiento de vuelo de plagas clave de hortícolas y sus enemigos naturales. 3. Evaluar el efecto directo de la radiación UV-A sobre el crecimiento poblacional de pulgones y mosca blanca, y sobre la fisiología de sus plantas hospederas, así como el efecto indirecto de la radiación UV-A en ambas plagas mediado por el crecimiento de dichas planta hospederas. 4. Caracterización de diversas mallas impregnadas en deltametrina y bifentrín con diferentes propiedades y selección de las óptimas para el control de pulgones, mosca blanca y sus virosis asociadas en condiciones de campo. Estudio de su compatibilidad con parasitoides. ABSTRACT Insect vectors of plant viruses are the main agents causing major economic losses in vegetable crops grown under protected environments. This Thesis focuses on the implementation of new alternatives to chemical control of insect vectors under Integrated Pest Management programs. In Spain, biological control is the main pest control strategy used in a large part of greenhouses where horticultural crops are grown. The first study aimed to increase our knowledge on how the presence of natural enemies such as Aphidius colemani Viereck may alter the dispersal of the aphid vector Aphis gossypii Glover (Chapter 4). In addition, it was investigated if the presence of this parasitoid affected the spread of aphid-transmitted viruses Cucumber mosaic virus (CMV, Cucumovirus) and Cucurbit aphid-borne yellows virus (CABYV, Polerovirus) infecting cucumber (Cucumis sativus L). SADIE methodology was used to study the distribution patterns of both the virus and its vector, and their degree of association. Results suggested that parasitoids promoted aphid dispersal in the short term, which enhanced CMV spread, though consequences of parasitism suggested potential benefits for disease control in the long term. Furthermore, A. colemani significantly limited the spread and incidence of the persistent virus CABYV in the long term. The flight activity of pests Myzus persicae (Sulzer), Bemisia tabaci (Gennadius) and Tuta absoluta (Meyrick), and natural enemies A. colemani and Sphaerophoria rueppellii (Weidemann) under UV-deficient environments was studied under field conditions (Chapter 5). One-chamber tunnels were covered with cladding materials with different UV transmittance properties. Inside each tunnel, insects were released from tubes placed in a platform suspended from the ceiling. Specific targets were located at different distances from the platform. The ability of aphids and whiteflies to reach their targets was diminished under UV-absorbing barriers, suggesting a reduction of vector activity under this type of nets. Fewer aphids reached distant traps under UV-absorbing nets, and significantly more aphids could fly to the end of the tunnels covered with non-UV blocking materials. Unlike aphids, differences in B. tabaci captures were mainly found in the closest targets. The oviposition of lepidopteran T. absoluta was also negatively affected by a UV-absorbing cover. The photoselective barriers were compatible with parasitism and oviposition of biocontrol agents. Apart from the direct response of insects to UV radiation, plant-mediated effects influencing insect performance were investigated (Chapter 6). The impact of UV-A radiation on the performance of aphid M. persicae and whitefly B. tabaci, and growth and leaf physiology of host plants pepper and eggplant was studied under glasshouse conditions. Plants were grown inside cages covered by transparent and UV-A-opaque plastic films. Plant growth and insect fitness were monitored. Leaves were harvested for chemical analysis. Pepper plants responded directly to UV-A by producing shorter stems whilst UV-A did not affect the leaf area of either species. UV-A-treated peppers had higher content of secondary metabolites, soluble carbohydrates, free amino acids and proteins. Such changes in tissue chemistry indirectly promoted aphid performance. For eggplants, chlorophyll and carotenoid levels decreased with supplemental UVA but phenolics were not affected. Exposure to supplemental UV-A had a detrimental effect on whitefly development, fecundity and fertility presumably not mediated by plant cues, as compounds implied in pest nutrition were unaltered. Lastly, the efficacy of a wide range of Long Lasting Insecticide Treated Nets (LLITNs) was studied under laboratory and field conditions. This strategy aimed to prevent aphids and whiteflies to enter the greenhouse by determining the optimum mesh size (Chapter 7). This new approach is based on slow release deltamethrin- and bifenthrin-treated nets with large hole sizes that allow improved ventilation of greenhouses. All LLITNs produced high mortality of M. persicae and A. gossypii although their efficacy decreased over time with sun exposure. It was necessary a net with hole size of 0.29 mm2 to exclude B. tabaci under laboratory conditions. The feasibility of two selected nets was studied in the field under a high insect infestation pressure in the presence of CMV- and CABYV-infected cucumber plants. Besides, the compatibility of parasitoid A. colemani with bifenthrin-treated nets was studied in parallel field experiments. Both nets effectively blocked the invasion of aphids and reduced the incidence of both viruses, however they failed to exclude whiteflies. We found that our LLITNs were compatible with parasitoid A. colemani. As shown, the role of natural enemies has to be taken into account regarding the dispersal of insect vectors and subsequent spread of plant viruses. The additional benefits of novel physicochemical barriers, such as photoselective and insecticide-impregnated nets, need to be considered in Integrated Pest Management programs of vegetable crops grown under protected environments.

Integrated Studies for the Evaluation of Conservation Treatments on Stone Material from Archaeological Sites. Application to the Case of Merida (Spain)

The research analyzes in detail and from different scales 15 houses in different climatic conditions and geographic regions in order to go deeper into the specific characteristics of each one of them from the perspective of sustainability. These houses are located in Tenerife, Salamanca, Huelva, Granada, Toledo, Madrid, Menorca, Alicante, Mallorca, Almería, La Coruña, Cantabria, Huesca and Lugo. The article analyzes the traditional dwelling, the natural environment and conditions that surround it and intends to discover the formal dialogue among them, as well as the origin of the design strategies

Country reports. Spain

Many diversified activities can be reported from the Spanish INHIGEO group. The International Year of Crystallography was celebrated on St. Albertus Magnus Day (January 28) at the National University of Distance Education at (Madrid). The scientist Santiago Garcia Granda, President of the European Association of Crystallography, was commissioned to present a lecture titled, Crystals and diffraction: 100 years of scientific milestones. An exhibition of minerals was held at the Madrid Mining School (November 24-29).

Construction History in Spain: the Discipline's Foundation

In the past two decades the History of Construction has started to become an independent discipline. On one hand, the number of articles, theses and books that could be assigned to this field has grown exponentially. Furthermore, there have been numerous and remarkably successful Congresses: 12 National (Spain 8; France 2; United Kingdom 1; Germany 1) and 4 International Congresses (Madrid 2003, Cambridge 2006, Cottbus 2009, Paris 2012), see Table 1 below. However, the situation is far from that corresponding to an already recognized discipline, such as the History of Art or the History of Science. There are no University chairs and departments, and in the reference databases “Construction History” is not listed as a common descriptor. This is not surprising; it reflects the inertia of academia to accept new disciplines. In what follows we will discuss the current state of discipline in Spain. Previous articles have tackled the matter. We will try to avoid unnecessary repetitions and concentrate on: 1) The activities of the Spanish Society of Construction History; 2) Its consequences on teaching and research, taken as a case study the experience in the School of Architecture of Madrid, and 3) We will give a provisional List of dissertations on Construction History read in Spain in the last forty years. First, we will try to define with the least possible ambiguity its field and its objectives. The intention is not to enter into the actual debate on the "definition" of Construction History, but to expose, in as detached as possible way, the ideas behind the actions made.

Discourses and values underpin public debate on fracking in Spain: a case study at the crossroad

In the EU context extraction of shale and oil gas by hydraulic fracturing (fracking) differs from country to country in terms of legislation and implementation. While fossil fuel extraction using this technology is currently taking place in the UK, Germany and France have adopted respective moratoria. In between is the Spanish case, where hydrocarbon extraction projects through fracking have to undergo mandatory and routine environmental assessment in accordance with the last changes to environmental regulations. Nowadays Spain is at the crossroad with respect to the future of this technology. We presume a social conflictt in our country since the position and strategy of the involved and confronted social actors -national, regional and local authorities, energy companies, scientists, NGO and other social organization- are going to play key and likely divergent roles in its industrial implementation and public acceptance. In order to improve knowledge on how to address these controverted situations from the own engineering context, the affiliated units from the Higher Technical School of Mines and Energy Engineering at UPM have been working on a transversal program to teach values and ethics. Over the past seven years, this pioneering experience has shown the usefulness of applying a consequentialist ethics, based on a case-by-case approach and costs-benefits analysis both for action and inaction. As a result of this initiative a theoretical concept has arisen and crystallized in this field: it is named Inter-ethics. This theoretical perspective can be very helpful in complex situations, with multi-stakeholders and plurality of interests, when ethical management requires the interaction between the respective ethics of each group; professional ethics of a single group is not enough. Under this inter-ethics theoretical framework and applying content analysis techniques, this paper explores the articulation of the discourse in favour and against fracking technology and its underlying values as manifested in the Spanish traditional mass media and emerging social media such as Youtube. Results show that Spanish public discourse on fracking technology includes the costs-benefits analysis to communicate how natural resources from local communities may be affected by these facilities due to environmental, health and economic consequences. Furthermore, this technology is represented as a solution to the "demand of energy" according to the optimistic discourse while, from a pessimistic view, fracking is often framed as a source "environmental problems" and even natural disasters as possible earthquakes. In this latter case, this negative representation could have been influenced by the closure of a macro project to store injected natural gas in the Mediterranean Sea using the old facilities of an oil exploitation in Amposta (Proyecto Cástor). The closure of this project was due to the occurrence of earthquakes whose intensity was higher than the originally expected by the experts in the assessment stage of the project.
