Do PGI integrated farms perform better? The case of the beef farms in Spain

European rural development policy is gaining in importance through one of its key instruments, the Protected Geographical Indications (PGI) system, which is designed to improve quality standards. Previous research has shown that PGI-certified beef farms tend to be more extensively managed operations that are better adapted to mountainous areas. This paper describes a comparative study of two production systems, one with PGI certification and one without, focusing on a number of economic variables. The results show a positive association between PGI production and profitability. In efficiency terms, non-certified farms show better pure technical efficiency scores, while PGI-certified holdings score higher on scale efficiency.

The determinants of the quality of Sales-Marketing Interface in a Multinational Customer Brand Focused Company: The Latin American Branches

Customer evolution and changes in consumers, determine the fact that the quality of the interface between marketing and sales may represent a true competitive advantage for the firm. Building on multidimensional theoretical and empirical models developed in Europe and on social network analysis, the organizational interface between the marketing and sales departments of a multinational high-growth company with operations in Argentina, Uruguay and Paraguay is studied. Both, attitudinal and social network measures of information exchange are used to make operational the nature and quality of the interface and its impact on performance. Results show the existence of a positive relationship of formalization, joint planning, teamwork, trust and information transfer on interface quality, as well as a positive relationship between interface quality and business performance. We conclude that efficient design and organizational management of the exchange network are essential for the successful performance of consumer goods companies that seek to develop distinctive capabilities to adapt to markets that experience vertiginous changes

Analysis of the geometric altimetry to support aircraft optimal profiles within future 4D trajectory management

The use of barometric altimetry is to some extent a limiting factor on safety, predictability and efficiency of aircraft operations, and reduces the potential of the trajectory based operations capabilities. However, geometric altimetry could be used to improve all of these aspects. Nowadays aircraft altitude is estimated by applying the International Standard Atmosphere which differs from real altitude. At different temperatures for an assigned barometric altitude, aerodynamic forces are different and this has a direct relationship with time, fuel consumption and range of the flight. The study explores the feasibility of using sensors providing geometric reference altitude, in particular, to supply capabilities for the optimization of vertical profiles and also, their impact on the vertical Air Traffic Management separation assurance processes. One of the aims of the thesis is to assess if geometric altitude fulfils the aeronautical requirements through existing sensors. Also the thesis will elaborate on the advantages of geometric altitude over the barometric altitude in terms of efficiency for vertical navigation. The evidence that geometric altitude is the best choice to improve the efficiency in vertical profile and aircraft capacity by reducing vertical uncertainties will also be shown. In this paper, an atmospheric study is presented, as well as the impact of temperature deviation from International Standard Atmosphere model is analyzed in order to obtain relationship between geometric and barometric altitude. Furthermore, an aircraft model to study aircraft vertical profile is provided to analyse trajectories based on geometric altitudes.

Geometric Study of the Weak Equilibrium in a Weighted Case for a Two-Dimensional Competition Game

In this work, an improvement of the results presented by [1] Abellanas et al. (Weak Equilibrium in a Spatial Model. International Journal of Game Theory, 40(3), 449-459) is discussed. Concretely, this paper investigates an abstract game of competition between two players that want to earn the maximum number of points from a finite set of points in the plane. It is assumed that the distribution of these points is not uniform, so an appropriate weight to each position is assigned. A definition of equilibrium which is weaker than the classical one is included in order to avoid the uniqueness of the equilibrium position typical of the Nash equilibrium in these kinds of games. The existence of this approximated equilibrium in the game is analyzed by means of computational geometry techniques.

Analysis of the geometric altimetry to support aircraft optimal trajectories within the future 4d trajectory management

Over the past few years, the common practice within air traffic management has been that commercial aircraft fly by following a set of predefined routes to reach their destination. Currently, aircraft operators are requesting more flexibility to fly according to their prefer- ences, in order to achieve their business objectives. Due to this reason, much research effort is being invested in developing different techniques which evaluate aircraft optimal trajectory and traffic synchronisation. Also, the inefficient use of the airspace using barometric altitude overall in the landing and takeoff phases or in Continuous Descent Approach (CDA) trajectories where currently it is necessary introduce the necessary reference setting (QNH or QFE). To solve this problem and to permit a better airspace management born the interest of this research. Where the main goals will be to evaluate the impact, weakness and strength of the use of geometrical altitude instead of the use of barometric altitude. Moreover, this dissertation propose the design a simplified trajectory simulator which is able to predict aircraft trajectories. The model is based on a three degrees of freedom aircraft point mass model that can adapt aircraft performance data from Base of Aircraft Data, and meteorological information. A feature of this trajectory simulator is to support the improvement of the strategic and pre-tactical trajectory planning in the future Air Traffic Management. To this end, the error of the tool (aircraft Trajectory Simulator) is measured by comparing its performance variables with actual flown trajectories obtained from Flight Data Recorder information. The trajectory simulator is validated by analysing the performance of different type of aircraft and considering different routes. A fuel consumption estimation error was identified and a correction is proposed for each type of aircraft model. In the future Air Traffic Management (ATM) system, the trajectory becomes the fundamental element of a new set of operating procedures collectively referred to as Trajectory-Based Operations (TBO). Thus, governmental institutions, academia, and industry have shown a renewed interest for the application of trajectory optimisation techniques in com- mercial aviation. The trajectory optimisation problem can be solved using optimal control methods. In this research we present and discuss the existing methods for solving optimal control problems focusing on direct collocation, which has received recent attention by the scientific community. In particular, two families of collocation methods are analysed, i.e., Hermite-Legendre-Gauss-Lobatto collocation and the pseudospectral collocation. They are first compared based on a benchmark case study: the minimum fuel trajectory problem with fixed arrival time. For the sake of scalability to more realistic problems, the different meth- ods are also tested based on a real Airbus 319 El Cairo-Madrid flight. Results show that pseudospectral collocation, which has shown to be numerically more accurate and computa- tionally much faster, is suitable for the type of problems arising in trajectory optimisation with application to ATM. Fast and accurate optimal trajectory can contribute properly to achieve the new challenges of the future ATM. As atmosphere uncertainties are one of the most important issues in the trajectory plan- ning, the final objective of this dissertation is to have a magnitude order of how different is the fuel consumption under different atmosphere condition. Is important to note that in the strategic phase planning the optimal trajectories are determined by meteorological predictions which differ from the moment of the flight. The optimal trajectories have shown savings of at least 500 [kg] in the majority of the atmosphere condition (different pressure, and temperature at Mean Sea Level, and different lapse rate temperature) with respect to the conventional procedure simulated at the same atmosphere condition.This results show that the implementation of optimal profiles are beneficial under the current Air traffic Management (ATM).

Propuesta de un marco conceptual para el análisis comparativo de las redes de distribución de dos supermercados online = Proposal of a conceptual framework for the comparative analysis of the distribution networks of two online supermarkets

In this article the network configuration for fulfillment and distribution of online orders of two British retailers is analyzed and compared. For this purpose, it is proposed a conceptual framework that consists of the key following aspects: network configuration, transportation management and location of demand. As a result is not obvious to determine the ideal centralization degree in each case. Finally, it is suggested the future development of an analytic tool that helps to choose the most appropriate model.

Aplicación de nuevas tecnologías en la Arqueología de la Guerra Civil Española: Los Yesares, Pinto (Madrid. Application of new technologies in archeology of the Civil War:The Yesares, Pinto (Madrid.

ABSTRACT: The surveys carried out in the municipality of Pinto (Madrid) have enabled us to locate various structural remains linked to the military operations that took place around the capital during the Spanish Civil War (1936-1939). In order to identify and record them, surveys were complemented with the use of GPS and air photographs from different time periods. Afterwards, and in collaboration with researchers from various universities, further methods aimed at generating a complete special representation of the area were applied directly to one of the sites which produced the best results, known as "los Yesares". These methods include topographic mapping that resulted in cartographic material at different scales, the photographic recording with flying Unmanned Aerial Vehicles, and the use of land scanners and GPS-corrected photogrammetrics with which to obtain 3D models.

Business, development and inclusive supply chains. Exploring pathways for the sustainable incorporation of the poor as suppliers in agrifood supply chains

El panorama global está cambiando, y esto influye sobre la forma en la que entendemos y tratamos de alcanzar un desarrollo humano sostenible. El crecimiento de la población conlleva una mayor presión sobre los recursos, pero también supone una mayor cantidad de mano de obra y de talento; la concentración en áreas urbanas está cambiando las dinámicas sociales y desafiando los canales de comercialización tradicionales, pero también genera nuevos mercados y fomenta la innovación; los cambios en la economía global están reduciendo los tradicionales desequilibrios de poder entre los países occidentales y el resto del mundo; y las crecientes interconexiones crean nuevos riesgos pero también oportunidades para lanzar iniciativas de alcance global. Todas estas tendencias nos están obligando a repensar qué es el desarrollo humano y de qué manera deberíamos afrontar el reto de la pobreza. Es comúnmente aceptado que la globalización implica interdependencia y que, para conseguir un desarrollo humano sostenible, la colaboración entre actores de distintos ámbitos es necesaria. Se observa una creciente convergencia de temas, intereses y soluciones en torno al desarrollo sostenible, incluso en diferentes países y sectores, lo que está facilitando la colaboración estratégica entre empresas, gobiernos y sociedad civil. Existen pocas duda a día de hoy sobre el papel fundamental que las empresas deben desempeñar en la transición mundial hacia la sostenibilidad ambiental y la erradicación de la pobreza. Las empresas están evolucionando desde un enfoque tradicional centrado en la maximización de beneficios económicos hacia un enfoque holístico que integra la sostenibilidad y la responsabilidad social como parte del núcleo de negocio de las compañías. En el ámbito medioambiental, muchas empresas ya han comenzado a actuar y tratan de reducir sus emisiones, sus desechos y su consumo de energía. Sin embargo la contribución de las empresas a la reducción de la pobreza no está tan clara. Actualmente en torno a 1,2 miles de millones de personas viven en situación de extrema pobreza. La mayoría de estas personas aún vive en zonas rurales donde la mayor parte de la población activa trabaja en el sector agrícola. Por lo tanto, mejorar las oportunidades y reducir los riesgos de los productores más vulnerables en el sector de la agricultura puede ser un motor de desarrollo rural y reducción de la pobreza, especialmente en países de bajo nivel de desarrollo cuyas economías están fundamentalmente basadas en la agricultura. Algunas empresas comienzan a incluir a los pobres en sus operaciones como consumidores, proveedores y emprendedores. Esta tesis se centra en las potenciales oportunidades relacionadas con la incorporación sostenible de los pobres como proveedores de productos y/o de mano de obra. La colaboración entre empresas y productores vulnerables de países en desarrollo es un tema relativamente nuevo y todavía poco estudiado. La pregunta que guía esta tesis es: “¿Cómo pueden las empresas facilitar la inclusión sostenible en cadenas de suministro de productores vulnerables de los países menos desarrollados?”. Para responder a la pregunta anterior, la autora ha aplicado una metodología de casos de estudio. Esta metodología se considera apropiada porque la investigación sobre cadenas de suministro inclusivas es todavía escasa y porque es necesario entender en profundidad un fenómeno de la vida real, y para ello es fundamental conocer su contexto. En primer lugar, se realiza una revisión de literatura para identificar las proposiciones y los constructos teóricos que guiarán la posterior recogida de datos. La revisión de literatura se divide en dos partes: una más general que explora la dimensión social de la sostenibilidad en cadenas de suministro, y una más específica que se centra en la incorporación de los pobres como proveedores en cadenas de suministro. A lo largo de la última década, ha habido un crecimiento exponencial de los estudios académicos sobre la sostenibilidad de las cadenas de suministro, pero la mayoría de los esfuerzos se han dirigido hacia la dimensión medioambiental de la sostenibilidad. Por lo tanto la revisión de literatura, que se presenta en la Sección 3.1 (página 35) y que profundiza en la sostenibilidad social de las cadenas de suministro, puede considerarse una contribución en sí misma. Esta revisión de literatura revela que la investigación sobre aspectos sociales en cadenas de suministro está cobrando impulso en distintas áreas de conocimiento, principalmente en los ámbitos de investigación sobre “gestión de cadenas de suministro”, “responsabilidad social corporativa” y “estudios del desarrollo”. La investigación existente sobre sostenibilidad social de cadenas de suministro se centra en tres temas: aclarar la definición de sostenibilidad social; analizar la implementación de estrategias de sostenibilidad social en cadenas de suministro; y estudiar el apoyo de las em presas líderes a proveedores vulnerables para facilitar su transición hacia la sostenibilidad. Un marco conceptual que resume los principales hallazgos de esta primera parte de la revisión de literatura es planteado en la Figura 7 (página 48). No obstante, en el área de investigación que está emergiendo en torno a la sostenibilidad social de las cadenas de suministro, los estudios relacionados con la reducción de la pobreza son aún escasos. Además se aprecia una falta de contribuciones desde y sobre los países menos desarrollados, así como una clara tendencia a reflejar la visión de las empresas líderes de las cadenas de suministro, olvidando la perspectiva de los proveedores. La segunda parte de la revisión de literatura presentada en la Sección 3.2 (página 51) profundiza en tres líneas de investigación que exploran, desde distintas perspectivas, la inclusión de los pobres en cadenas de suministro. Estas líneas son “Global Value Chains” (GVC), “Base of the Pyramid” (BoP) y “Sustainable Supply Chain Management” (SSCM). La investigación en GVC analiza las cadenas de suministro desde la perspectiva de la globalización económica y el comercio internacional, poniendo especial énfasis en las implicaciones para los países en desarrollo y las comunidades vulnerables. GVC caracteriza las cadenas de suministro según la forma en la que son gobernadas, las oportunidades de mejora que existen para los productores que forman parte de la cadena y el grado de inclusión o exclusión de las comunidades más pobres y vulnerables. La investigación en BoP explora las relaciones comerciales entre empresas y comunidades pobres. La premisa fundamental del concepto BoP es la posibilidad de combinar la generación de beneficios con la reducción de la pobreza. La propuesta original es que mediante la venta de productos y servicios a las comunidades pobres de países en desarrollo, la pobreza puede ser reducida al tiempo que las empresas incrementan sus beneficios, especialmente las grandes empresas multinacionales. Esta idea ha ido evolucionando y, a día de hoy, los investigadores BoP consideran la incorporación de los pobres no sólo como consumidores sino también como empleados, proveedores y co-creadores. La investigación en SSCM ha estado fundamentalmente orientada al estudio de la dimensión medioambiental de la sostenibilidad de cadenas de suministro. Sin embargo, la creciente externalización de la producción a países en desarrollo y las demandas de los grupos de interés para que las empresas aborden todos los aspectos de la sostenibilidad han llevado a los académicos de SSCM a reconocer la importancia de integrar asuntos relacionados con la reducción de la pobreza en sus investigaciones. Algunos estudios comienzan a apuntar los principales retos a los que se enfrentan las empresas para colaborar con productores vulnerables en sus cadenas de suministro. Estos retos son: falta de comunicación, altos costes de transacción y el incremento de la complejidad de las operaciones. Las contribuciones de estas tres líneas de investigación son complementarias para el estudio de las cadenas de suministro inclusivas. Sin embargo, raramente han sido consideradas conjuntamente, ya que pertenecen a ámbitos de conocimiento distintos. Esta tesis integra las aportaciones de GVC, BoP y SSCM en un marco conceptual para la creación y gestión de cadenas de suministro inclusivas. Este marco conceptual para cadenas de suministro inclusivas queda representado en la Figura 9 (página 68). El marco conceptual refleja las motivaciones que llevan a las empresas a colaborar con productores vulnerables, los retos a los que se enfrentan al hacerlo, y los caminos o estrategias que están siguiendo para construir y operar cadenas de suministro inclusivas de manera que sean beneficiosas tanto para la empresa como para los productores vulnerables. A fin de validar y refinar el marco conceptual propuesto, tres casos de estudio se llevan a cabo. Las cadenas de suministro analizadas por los casos de estudio pertenecen al sector agrícola y sus principales proveedores se encuentran en países de África subsahariana. Múltiples métodos de recolección de datos y triangulación son utilizados para mejorar la fiabilidad de los datos. La autora desarrolló trabajos de campo en Senegal, Etiopía y Tanzania. Estos viajes permitieron enriquecer el proceso de recogida de información mediante entrevistas semiestructuradas y conversaciones informales con los principales actores de la cadena de suministro y mediante la observación directa de los procesos y las interacciones entre productores vulnerables y empresas. El Caso de estudio A (Sección 5.1 en página 96) es un caso de estudio único. Analiza la cadena de suministro local de verduras en Senegal. La organización focal es Manobi, una empresa senegalesa que provee servicios de bajo coste a emprendedores locales del sector agrícola. El Caso de estudio A proporciona un interesante análisis del funcionamiento de una cadena de suministro local en un país en desarrollo y muestra como la provisión de servicios profesionales puede mejorar el desempeño de productores vulnerables. El Caso de estudio B (Sección 5.2 en página 122) es un caso de estudio único. Analiza la cadena de suministro global de flor cortada con origen en Etiopía. La organización focal es EHPEA, la Asociación Etíope de Productores y Exportadores Hortícolas, cuya misión es promover y salvaguardar la posición competitiva del sector agrícola etíope en el mercado global. El Caso de estudio B ayuda a comprender mejor la perspectiva de los proveedores respecto a los requerimiento de sostenibilidad del mercado global. También muestra cómo la inclusión de los productores en el proceso de desarrollo de un estándar privado facilita su implementación posterior. El Caso de estudio C (Sección 5.3 en página 143) es un caso de estudio múltiple. Analiza la cadena de suministro global de café especial con origen en Tanzania. Las organizaciones focales son comerciantes que conectan de manera directa a pequeños agricultores de café en países en desarrollo con empresas tostadoras de café en países desarrollados. El Caso de estudio C muestra cómo un pequeño agricultor puede proveer un producto “premium” al mercado global, y participar en un segmento diferenciado del mercado a través de una cadena de suministro transparente y eficiente. Las aportaciones empíricas de los casos de estudio ayudan a validar y mejorar el marco conceptual sobre cadenas de suministro inclusivas (ver discusión en el Capítulo 6 en página 170). El resultado es la propuesta de una nueva versión del marco conceptual representado en la Figura 40 (página 195). Los casos de estudio también proporcionan interesantes aportaciones en relación a la gestión de cadenas de suministro inclusivas y muestran las perspectivas de distintos actores implicados. Esta tesis arroja luz sobre el papel de las empresas en la creación y la gestión de cadenas de suministro inclusivas llevando a cabo una revisión de literatura multidisciplinar y analizando tres casos de estudio en países africanos. Como resultado, esta tesis presenta una serie de contribuciones empíricas y teóricas al ámbito de investigación emergente en torno a las cadenas de suministro inclusivas (Capítulo 7). Esta tesis también pretende ser útil a profesionales que deseen facilitar la incorporación de los pobres como proveedores en condiciones justas y beneficiosas. ABSTRACT The global outlook is changing, and this is influencing the way we understand and try to achieve sustainable human development. Population growth entails increasing pressure over resources, but it also provides greater workforce and talent; concentration in urban areas is changing social dynamics and challenging traditional marketing channels, but also creating news markets and driving innovation; the global economy shift is rebalancing the traditional power imbalance between Western countries and the rest of the world, making new opportunities to arise; and interconnections and global interdependence create new risks but also opportunities for launching initiatives with a global reach. All these trends are impelling us to rethink what development is and in which way poverty alleviation should be approached. It is generally agreed that globalization implies interdependence and, in order to achieve sustainable human development, collaboration of all actors is needed. A convergence of issues, interests and solutions related to sustainable development is being observed across countries and sectors, encouraging strategic collaboration among companies, governments and civil society. There is little doubt nowadays about the crucial role of the private sector in the world’s path towards environmental sustainability and poverty alleviation. Businesses are evolving from a “business as usual” stance to a more sustainable and responsible approach. In the environmental arena, many companies have already “walk the talk”, implementing environmental management systems and trying to reduce emissions and energy consumption. However, regarding poverty alleviation, their contribution is less clear. There are around 1.2 billion people living in extreme poverty. Most of this people still live in rural areas where the agricultural sector employs a big part of the active population. Therefore, improving opportunities and reducing risks for vulnerable producers in the agri-food sector can be a primary engine of rural development and poverty alleviation, particularly in the poor, agriculture-based economies of least developed countries. Some companies are beginning to include the poor into their operations as consumers, suppliers and entrepreneurs. This thesis focuses specifically on the potential opportunities related to the sustainable incorporation of the poor as suppliers of products and/or labor. Business collaboration with vulnerable producers in developing countries is a relatively new trend and it is still understudied. The overall question guiding this thesis is: “How can businesses facilitate the sustainable inclusion of vulnerable producers from least developed countries into supply chains?”. In order to answer the research question, the author has applied a case study research strategy. This methodology is considered appropriate because research about inclusive supply chains is still at an early stage, and because there is a need to understand a real-life phenomenon in depth, but such understanding encompasses important contextual conditions. First, a literature review is conducted, in order to identify the research propositions and theoretical constructs that will guide the data collection. The literature review is divided in two parts: a more general one that explores the social dimension of sustainability of supply chains, and a more specific one that focuses on the incorporation of the poor as suppliers in supply chains. During the last decade, there has been an exponential growth of studies in the field of supply chain sustainability, but research efforts have traditionally been directed towards the analysis of the environmental dimension. Therefore, the literature review presented in Section 3.1 (page 35) that delves into social sustainability of supply chains can be considered a contribution in itself. This literature review reveals that the investigation of social issues in supply chains is gaining momentum and comes from different academic disciplines, namely Supply Chain Management, Corporate Social Responsibility and Development Studies. Existing research about social sustainability of supply chains focuses on three issues: clarify the definition of social sustainability; analyze the implementation of social sustainability strategies in supply chains; and study lead companies’ support to vulnerable suppliers in their transition towards sustainability. A conceptual framework that outlines the main findings that emerge from this first part of literature review is proposed in Figure 7 (page 48). Nevertheless, in this nascent field of social sustainability of supply chains, studies related to poverty alleviation are still scarce. Moreover, a lack of contributions from and about least developed countries has been observed, as well as a tendency to reflect on the lead firms’ standpoint, neglecting the suppliers’ perspective. The second part of the literature review (Section 3.2 in page 51) delves into three research streams that are exploring the inclusion of the poor into supply chains from different viewpoints. These research streams are Global Value Chains (GVC), Base of the Pyramid (BoP) and Sustainable Supply Chain Management (SSCM). GVC research discusses the dynamics of economic globalization and international trade, putting special emphasis in the implications for developing countries and vulnerable communities. GVC characterizes supply chains by the way they are governed, the upgrading opportunities that exist for producers in the chain and the degree of inclusion or exclusion of impoverished communities. BoP research explores trading relationships between businesses and impoverished communities. The core premise of the BoP concept is the possibility to combine profits with poverty alleviation. The original BoP proposition is that by marketing innovative products and services to poor communities in developing countries, poverty would be reduced and companies would increase their benefits, especially multinational companies. This idea has evolved to consider the incorporation of the poor to business activities not only as consumers, but also as employees, entrepreneurs and co-creators. The SSCM school of thought has mainly focused on studying the environmental dimension of supply chain sustainability, neglecting the consideration of the social perspective. However, in recent years, increasing outsourcing of production to developing countries and stakeholders’ demands for a more holistic approach to business sustainability have led SSCM scholars to acknowledge the importance of integrating poverty concerns in this field’s research agenda. Some SSCM studies identify the main operational challenges for companies which engage with vulnerable suppliers in their supply chains: missing communication, higher transactional and operational costs and increased complexity. Contributions from these three research streams are complementary for the study of inclusive supply chains. However, they have been rarely considered together, since they belong to different research areas. This thesis seeks to play a dovetailing role in this scenario by proposing a conceptual framework for creating and operating inclusive supply chains that builds on contributions from GVC, SSCM and BoP research. This framework for inclusive supply chains is depicted in Figure 9 (page 68), and explains the motivations that drive businesses to collaborate with vulnerable suppliers, the chal lenges they face in doing so, and the pathways they are following in order to build and operate inclusive supply chains profitably for both buying companies and vulnerable suppliers. In order to validate and refine the proposed framework, three case studies are carried out. The supply chains analyzed by the case studies belong to the agri-food sector and source from Sub-Saharan African countries. Multiple data collection methods and triangulation are used in order to improve reliability of findings. The author carried out field work in Senegal, Ethiopia and Tanzania. These travels enriched the data collection process, providing semi-structured interviews and informal conversations with the main actors in the supply chains, as well as direct observation of processes and interactions among companies and vulnerable suppliers. Case study A (Section 5.1 in page 96) is a single case study. It analyzes a local supply chain in Senegal providing vegetables to the local market. The focal organization is Manobi, a Senegalese inclusive business which provides affordable ICT services to local entrepreneurs in the agri-food sector. Case study A provides interesting insights into the dynamics of local supply chains and how professional services can help to improve their performance. Case study B (Section 5.2 in page 122) is a single case study. It analyzes a global supply chain with origin in Ethiopia providing cut flowers to the global commodity market. The focal organization is EHPEA, Ethiopian Horticulture Producers and Exporters Association, whose mission is to promote and safeguard the competitive position of the Ethiopian horticulture sector within the global market. Case study B helps to better understand the suppliers’ perspective regarding global market sustainability requirements and shows how the inclusion of suppliers in the process of development of a private standard has a positive impact in its implementation. Case study C (Section 5.3 in page 143) is a multiple case study. It analyzes a global supply chain with origin in Tanzania providing coffee to the global niche market of specialty coffee. The focal organizations are traders who are directly connecting smallholder coffee farmers in developing countries to coffee roasters in developed countries. Case study C shows how smallholder farmers can supply a premium product and be incorporated in a differentiated market segment through a transparent and efficient supply chain. The empirical findings from the case studies help to validate and refine the conceptual framework (see discussion in Chapter 6). The proposal of a new version of the conceptual framework is depicted in Figure 40 (page 195). The case studies also provide interesting insights related to the management of inclusive supply chains and show the perspectives of the different actors involved. This thesis sheds some light on the role of businesses in the creation and operation of inclusive supply chains by carrying out a cross-disciplinary literature review and analyzing three case studies in African countries. In doing so, this thesis presents a series of theoretical and empirical contributions to the emerging academic field of inclusive supply chains (Chapter 7). This thesis also intends to be useful to practitioners willing to improve the incorporation of the poor as suppliers in fair and profitable conditions.

A taste of the technical cuisine: metals and other ingredients

According to cognitive linguistics, language has an experiential origin based on perception, sensory motor activities and our knowledge of the world. Our thought operates by establishing similarities, links and associations that enable us to talk about one thing in terms of another as shown in the example of love as a journey (Lakoff and Johnson, 1980). Metaphor and metonymy are conceptual and linguistic tools that make possible most of these cognitive operations. Since metaphor is an essential element of human communication, the discourse of specialised disciplines includes metaphorical mappings and numerous examples of metaphorical expressions, for example in economics, where business is mapped in terms of war (White, 2004; Herrera & White, 2000), electrotechnics with electrical components understood as couples (Roldán- Riejos in preparation) or in civil engineering where a bridge is conceptualized as a person (Roldán-Riejos, 2013). In this paper, the metaphors: WORKING WITH METALS IS COOKING/ TRABAJAR CON METALES ES COCINAR and METALS ARE CULINARY OBJECTS/ LOS METALES SON OBJETOS CULINARIOS are explored. The main aim is to show that the cooking metaphor is widely spread in the metallurgical domain in English and Spanish, although with different nuances in each language due to socio-cultural factors. The method adopted consists of analysing examples taken from the: Bilingual Dictionary of Scientific and Technical Metaphors and Metonymies Spanish- English/English-Spanish, a forthcoming and rigorously documented bilingual dictionary that sums up research on conceptual, linguistic and visual metaphor and metonymy in different areas of engineering (Roldán-Riejos and Molina, 2013). The present paper studies in detail English and Spanish cross-linguistic correspondences related to types of metals and processes. It is suggested that they reflect synesthetic metaphoric mappings. The exploitation of cognitive conceptual metaphor in the ESP classroom is lastly recommended.

Pre-investigation of water electrolysis for flexible energy storage at large scales: the case of the Spanish power system

This report analyzes the basis of hydrogen and power integration strategies, by using water electrolysis processes as a means of flexible energy storage at large scales. It is a prospective study, where the scope is to describe the characteristics of current power systems (like the generation technologies, load curves and grid constraints), and define future scenarios of hydrogen for balancing the electrical grids, considering the efficiency, economy and easiness of operations. We focus in the "Spanish case", which is a good example for planning the transition from a power system holding large reserve capacities, high penetration of renewable energies and limited interconnections, to a more sustainable energy system being capable to optimize the volumes, the regulation modes, the utilization ratios and the impacts of the installations. Thus, we explore a novel aspect of the "hydrogen economy" which is based in the potentials of existing power systems and the properties of hydrogen as energy carrier, by considering the electricity generation and demand globally and determining the optimal size and operation of the hydrogen production processes along the country; e.g. the cost production of hydrogen becomes viable for a base-load scenario with 58 TWh/year of power surplus at 0.025 V/kWh, and large number electrolyzer plants (50 MW) running in variable mode (1-12 kA/m2)

GovCloud: the usage of cloud computing in public organizations

It has been shown that cloud computing brings cost benefits and promotes efficiency in the operations of the organizations, no matter what their type or size. However, few public organizations are benefiting from this new paradigm shift in the way the organizations consume and manage computational resources. The objective of this thesis is to analyze both internal and external factors that may influence the adoption of cloud computing by public organizations and propose possible strategies that can assist these organizations in their path to cloud usage. In order to achieve this objective, a SWOT analysis has been conducted, detecting internal factors (strengths and weaknesses) and external factors (opportunities and threats) that can influence the adoption of a governmental cloud. With the application of a TOWS matrix, by combining the internal and external factors, a list of possible strategies have been formulated to be used as a guide to decision-making related to the transition to a cloud environment.
