Since the introduction of the Doi Moi ('renovation') economic reform in 1986, Vietnam has experienced a transformation of its economic management, from a central planning economy to a market-oriented economy. High economic growth, created by the liberalization of activities in all sectors of the economy, has changed the economic structure of the country, and the once agriculture-based and poverty-stricken land now generates a midlevel income and possesses many industrial bases. Economic growth has also changed the landscape of the country. Business complexes have been built in metropolises like Ho Chi Minh City and Hanoi, and rice fields have been converted into industrial zones. As the number of enterprises increased, areas began to emerge where many enterprises agglomerated. Some of these 'clusters' were groups of cottage industry households, while many others were large-scale industrial clusters. As Porter [1998] argues, industrial clusters are the source of a nation's 'competitive advantage'. McCarty et al. [2005] indicate that in some key industries in Vietnam, some clusters of enterprises have been created, although the degree of agglomeration differs from one industry to another. Using industry census data from 2001, they include dot density maps for the 12 leading manufacturing industries in Vietnam. They show that most of the industries analyzed are clustered either in Hanoi or Ho Chi Minh City (or both). Among these 12 industries, the garments industry has the greatest tendency to cluster, followed by textile, rice, seafood, and paper industries. The fact that industrial clusters have begun to form in some areas could be a positive sign for Vietnam's future economic development. What is lacking in McCarty et al. [2005], however, is the identification of the participants in the industrial clusters. Some argue for the importance of small and medium enterprises (SMEs) in Vietnam's economic development (e.g. Nguyen Tri Thanh [2007], Tran Tien Cuong et al. [2008]), while others stress the impact of foreign direct investments (FDI) (for example, Tuan Bui [2009]). Adding information about the participants in the above cluster study (and in other studies of spatial patterns of location of enterprises) may broaden the scope for analysis of economic development in Vietnam. This study aims to reveal the characteristics of industrial clusters in terms of their participants and locations. The findings of the study may provide basic information for evaluating the effects of agglomeration and the robustness of the effects in the industrial clusters in Vietnam. Section 1 describes the characteristics of economic entities in Vietnam such as ownership, size of enterprise, and location. Section 2 examines qualitative aspects of industrial clusters identified in McCarty et al. [2005] and uses information on the size and ownership of clusters. Three key industries (garments, consumer electronics, and motor vehicle) are selected for the study. Section 3 identifies another type of cluster commonly seen in Vietnam, composed of local industries and called 'craft villages'. Many such villages have been developed since the early 1990s. The study points out that some of these villages have become industrialized (or are becoming industrialized) by introducing modern modes of production and by employing thousands of laborers.

With the advancement of Information and Communication Technology ICT which favors increasingly fast, easy, and accessible communication for all and which can reach large groups of people, there have been changes, in recent years in our society that have modified the way we interact, communicate and transmit information. Access to this, it is possible, not only through computers situated in a fixed location, but new mobile devices make it available, wherever the user happens to be located. Now, information "travels" with the user. These forms of communication, transmission and access to information, have also affected the way to conceive and manage business. To these new forms of business that the Internet has brought, is now added the concept of companies in the Cloud Computing ClC. The ClC technology is based on the supply and consumption of services on demand and pay per use, and it gives a 180 degree turn to the business management concept. Small and large businesses may use the latest developments in ICT, to manage their organizations without the need for expensive investments in them. This will enable enterprises to focus more specifically within the scope of their business, leaving the ICT control to the experts. We believe that education can also and should benefit from these new philosophies. ?Due to the global economic crisis in general and each country in particular, economic cutbacks have come to most universities. These are seen in the need to raise tuition rates, which makes increasingly fewer students have the opportunity to pursue higher education?. In this paper we propose using ClC technologies in universities and we make a dissertation on the advantages that it can provide to both: universities and students. For the universities, we expose two focuses, one: ?to reorganize university ICT structures with the ClC philosophy? and the other one, ?to extend the offer of the university education with education on demand?. Regarding the former we propose to use public or private Clouds, to reuse resources across the education community, to save costs on infrastructure investment, in upgrades and in maintenance of ICT, and paying only for what you use and with the ability to scale according to needs. Regarding the latter, we propose an educational model in the ClC, to increase the current university offerings, using educational units in the form of low-cost services and where students pay only for the units consumed on demand. For the students, they could study at any university in the world (virtually), from anywhere, without travel costs: money and time, and what is most important paying only for what they consume. We think that this proposal of education on demand may represent a great change in the current educational model, because strict registration deadlines disappear, and also the problem of economically disadvantaged students, who will not have to raise large amounts of money for an annual tuition. Also it will decrease the problem of loss of the money invested in an enrollment when the student dropout. In summary we think that this proposal is interesting for both, universities and students, we aim for "Higher education from anywhere, with access from any mobile device, at any time, without requiring large investments for students, and with reuse and optimization of resources by universities. Cost by consumption and consumption by service?. We argue for a Universal University "wisdom and knowledge accessible to all?

The automation of domestic services began to be implemented in buildings since the late nineteenth century, and today we are used to terms like ‘intelligent buildings’, ‘digital home’ or ‘domotic buildings’. These concepts tell us about constructions which integrate new technologies in order to improve comfort, optimize energy consumption or enhance the security of users. In conjunction, building regulations have been updated to suit the needs of society and to regulate these new facilities in such structures. However, we are not always sure about how far, from the quantitative or qualitative point of view, legislation should regulate certain aspects of the building activity. Consequently, content analysis is adopted in this research to determine the influence of building regulations in the implementation of new technologies in the construction process. This study includes the analysis of different European regulations, the collection and documentation of such guidelines that have been established and a study of the impact that all of these have had in the way we start thinking an architectural project. The achievements of the research could be explained in terms of the regulatory requirements that must be taken into account in order to achieve a successful implementation of a home automation system, and the key finding has been the confirmation of how the design of smart buildings may be promoted through specific regulatory requirements while other factors, such as the global economic situation, do not seem to affect directly the rate of penetration of home automation in construction.

En la situación actual donde los sistemas TI sanitarios son diversos con modelos que van desde soluciones predominantes, adoptadas y creadas por grandes organizaciones, hasta soluciones a medida desarrolladas por cualquier empresa de la competencia para satisfacer necesidades concretas. Todos estos sistemas se encuentran bajo similares presiones financieras, no sólo de las condiciones económicas mundiales actuales y el aumento de los costes sanitarios, sino también bajo las presiones de una población que ha adoptado los avances tecnológicos actuales, y demanda una atención sanitaria más personalizable a la altura de esos avances tecnológicos que disfruta en otros ámbitos. El objeto es desarrollar un modelo de negocio orientado al soporte del intercambio de información en el ámbito clínico. El objetivo de este modelo de negocio es aumentar la competitividad dentro de este sector sin la necesidad de recurrir a expertos en estándares, proporcionando perfiles técnicos cualificados menos costosos con la ayuda de herramientas que simplifiquen el uso de los estándares de interoperabilidad. Se hará uso de especificaciones abiertas ya existentes como FHIR, que publica documentación y tutoriales bajo licencias abiertas. La principal ventaja que nos encontramos es que ésta especificación presenta un giro en la concepción actual de la disposición de información clínica, vista hasta ahora como especial por el requerimiento de estándares más complejos que solucionen cualquier caso por específico que sea. Ésta especificación permite hacer uso de la información clínica a través de tecnologías web actuales (HTTP, HTML, OAuth2, JSON, XML) que todo el mundo puede usar sin un entrenamiento particular para crear y consumir esta información. Partiendo por tanto de un mercado con una integración de la información casi inexistente, comparada con otros entornos actuales, hará que el gasto en integración clínica aumente dramáticamente, dejando atrás los desafíos técnicos cuyo gasto retrocederá a un segundo plano. El gasto se centrará en las expectativas de lo que se puede obtener en la tendencia actual de la personalización de los datos clínicos de los pacientes, con acceso a los registros de instituciones junto con datos ‘sociales/móviles/big data’.---ABSTRACT---In the current situation IT health systems are diverse, with models varying from predominant solutions adopted and created by large organizations, to ad-hoc solutions developed by any company to meet specific needs. However, all these systems are under similar financial pressures, not only from current global economic conditions and increased health care costs, but also under pressure from a population that has embraced the current technological advances, and demand a more personalized health care, up to those enjoyed by technological advances in other areas. The purpose of this thesis is to develop a business model aimed at the provision of information exchange within the clinical domain. It is intended to increase competitiveness in the health IT sector without the need for experts in standards, providing qualified technical profiles less expensively with the help of tools that simplify the use of interoperability standards. Open specifications, like FHIR, will be used in order to enable interoperability between systems. The main advantage found within FHIR is that introduces a shift in the current conception of available clinical information. So far seen, the clinical information domain IT systems, as a special requirement for more complex standards that address any specific case. This specification allows the use of clinical information through existing web technologies (HTTP, HTML, OAuth2, JSON and XML), which everyone can use with no particular training to create and consume this information. The current situation in the sector is that the integration of information is almost nonexistent, compared to current trends. Spending in IT health systems will increase dramatically within clinical integration for the next years, leaving the technical challenges whose costs will recede into the background. The investment on this area will focus on the expectations of what can be obtained in the current trend of personalization of clinical data of patients with access to records of institutions with ‘social /mobile /big data’.

The global economic structure, with its decentralized production and the consequent increase in freight traffic all over the world, creates considerable problems and challenges for the freight transport sector. This situation has led shipping to become the most suitable and cheapest way to transport goods. Thus, ports are configured as nodes with critical importance in the logistics supply chain as a link between two transport systems, sea and land. Increase in activity at seaports is producing three undesirable effects: increasing road congestion, lack of open space in port installations and a significant environmental impact on seaports. These adverse effects can be mitigated by moving part of the activity inland. Implementation of dry ports is a possible solution and would also provide an opportunity to strengthen intermodal solutions as part of an integrated and more sustainable transport chain, acting as a link between road and railway networks. In this sense, implementation of dry ports allows the separation of the links of the transport chain, thus facilitating the shortest possible routes for the lowest capacity and most polluting means of transport. Thus, the decision of where to locate a dry port demands a thorough analysis of the whole logistics supply chain, with the objective of transferring the largest volume of goods possible from road to more energy efficient means of transport, like rail or short-sea shipping, that are less harmful to the environment. However, the decision of where to locate a dry port must also ensure the sustainability of the site. Thus, the main goal of this article is to research the variables influencing the sustainability of dry port location and how this sustainability can be evaluated. With this objective, in this paper we present a methodology for assessing the sustainability of locations by the use of Multi-Criteria Decision Analysis (MCDA) and Bayesian Networks (BNs). MCDA is used as a way to establish a scoring, whilst BNs were chosen to eliminate arbitrariness in setting the weightings using a technique that allows us to prioritize each variable according to the relationships established in the set of variables. In order to determine the relationships between all the variables involved in the decision, giving us the importance of each factor and variable, we built a K2 BN algorithm. To obtain the scores of each variable, we used a complete cartography analysed by ArcGIS. Recognising that setting the most appropriate location to place a dry port is a geographical multidisciplinary problem, with significant economic, social and environmental implications, we consider 41 variables (grouped into 17 factors) which respond to this need. As a case of study, the sustainability of all of the 10 existing dry ports in Spain has been evaluated. In this set of logistics platforms, we found that the most important variables for achieving sustainability are those related to environmental protection, so the sustainability of the locations requires a great respect for the natural environment and the urban environment in which they are framed.

La estructura económica mundial, con centros de producción y consumo descentralizados y el consiguiente aumento en el tráfico de mercancías en todo el mundo, crea considerables problemas y desafíos para el sector del transporte de mercancías. Esta situación ha llevado al transporte marítimo a convertirse en el modo más económico y más adecuado para el transporte de mercancías a nivel global. De este modo, los puertos marítimos se configuran como nodos de importancia capital en la cadena de suministro al servir como enlace entre dos sistemas de transporte, el marítimo y el terrestre. El aumento de la actividad en los puertos marítimos produce tres efectos indeseables: el aumento de la congestión vial, la falta de espacio abierto en las instalaciones portuarias y un impacto ambiental significativo en los puertos marítimos. Los puertos secos nacen para favorecer la utilización de cada modo de transporte en los segmentos en que resultan más competitivos y para mitigar estos problemas moviendo parte de la actividad en el interior. Además, gracias a la implantación de puertos secos es posible discretizar cada uno de los eslabones de la cadena de transporte, permitiendo que los modos más contaminantes y con menor capacidad de transporte tengan itinerarios lo más cortos posible, o bien, sean utilizados únicamente para el transporte de mercancías de alto valor añadido. Así, los puertos secos se presentan como una oportunidad para fortalecer las soluciones intermodales como parte de una cadena integrada de transporte sostenible, potenciando el transporte de mercancías por ferrocarril. Sin embargo, su potencial no es aprovechado al no existir una metodología de planificación de la ubicación de uso sencillo y resultados claros para la toma de decisiones a partir de los criterios ingenieriles definidos por los técnicos. La decisión de dónde ubicar un puerto seco exige un análisis exhaustivo de toda la cadena logística, con el objetivo de transferir el mayor volumen de tráfico posible a los modos más eficientes desde el punto de vista energético, que son menos perjudiciales para el medio ambiente. Sin embargo, esta decisión también debe garantizar la sostenibilidad de la propia localización. Esta Tesis Doctoral, pretende sentar las bases teóricas para el desarrollo de una herramienta de Herramienta de Ayuda a la Toma de Decisiones que permita establecer la localización más adecuada para la construcción de puertos secos. Este primer paso es el desarrollo de una metodología de evaluación de la sostenibilidad y la calidad de las localizaciones de los puertos secos actuales mediante el uso de las siguientes técnicas: Metodología DELPHI, Redes Bayesianas, Análisis Multicriterio y Sistemas de Información Geográfica. Reconociendo que la determinación de la ubicación más adecuada para situar diversos tipos de instalaciones es un importante problema geográfico, con significativas repercusiones medioambientales, sociales, económicos, locacionales y de accesibilidad territorial, se considera un conjunto de 40 variables (agrupadas en 17 factores y estos, a su vez, en 4 criterios) que permiten evaluar la sostenibilidad de las localizaciones. El Análisis Multicriterio se utiliza como forma de establecer una puntuación a través de un algoritmo de scoring. Este algoritmo se alimenta a través de: 1) unas calificaciones para cada variable extraídas de información geográfica analizada con ArcGIS (Criteria Assessment Score); 2) los pesos de los factores obtenidos a través de un cuestionario DELPHI, una técnica caracterizada por su capacidad para alcanzar consensos en un grupo de expertos de muy diferentes especialidades: logística, sostenibilidad, impacto ambiental, planificación de transportes y geografía; y 3) los pesos de las variables, para lo que se emplean las Redes Bayesianas lo que supone una importante aportación metodológica al tratarse de una novedosa aplicación de esta técnica. Los pesos se obtienen aprovechando la capacidad de clasificación de las Redes Bayesianas, en concreto de una red diseñada con un algoritmo de tipo greedy denominado K2 que permite priorizar cada variable en función de las relaciones que se establecen en el conjunto de variables. La principal ventaja del empleo de esta técnica es la reducción de la arbitrariedad en la fijación de los pesos de la cual suelen adolecer las técnicas de Análisis Multicriterio. Como caso de estudio, se evalúa la sostenibilidad de los 10 puertos secos existentes en España. Los resultados del cuestionario DELPHI revelan una mayor importancia a la hora de buscar la localización de un Puerto Seco en los aspectos tenidos en cuenta en las teorías clásicas de localización industrial, principalmente económicos y de accesibilidad. Sin embargo, no deben perderse de vista el resto de factores, cuestión que se pone de manifiesto a través del cuestionario, dado que ninguno de los factores tiene un peso tan pequeño como para ser despreciado. Por el contrario, los resultados de la aplicación de Redes Bayesianas, muestran una mayor importancia de las variables medioambientales, por lo que la sostenibilidad de las localizaciones exige un gran respeto por el medio natural y el medio urbano en que se encuadra. Por último, la aplicación práctica refleja que la localización de los puertos secos existentes en España en la actualidad presenta una calidad modesta, que parece responder más a decisiones políticas que a criterios técnicos. Por ello, deben emprenderse políticas encaminadas a generar un modelo logístico colaborativo-competitivo en el que se evalúen los diferentes factores tenidos en cuenta en esta investigación.

En las últimas tres décadas, las dinámicas de restructuración económica a nivel global han redefinido radicalmente el papel de las ciudades. La transición del keynesianismo al neoliberalismo ha provocado un cambio en las políticas urbanas de los gobiernos municipales, que han abandonado progresivamente las tareas de regulación y redistribución para centrarse en la promoción del crecimiento económico y la competitividad. En este contexto, muchas voces críticas han señalado que la regeneración urbana se ha convertido en un vehículo de extracción de valor de la ciudad y está provocando la expulsión de los ciudadanos más vulnerables. Sin embargo, la regeneración de áreas consolidadas supone también una oportunidad de mejora de las condiciones de vida de la población residente, y es una política necesaria para controlar la expansión de la ciudad y reducir las necesidades de desplazamiento, promoviendo así ciudades más sostenibles. Partiendo de la hipótesis de que la gobernanza de los procesos de regeneración urbana es clave en el resultado final de las operaciones y determina el modelo de ciudad resultante, el objetivo de esta investigación es verificar si la regeneración urbana es necesariamente un mecanismo de extracción de valor o si puede mejorar la calidad de vida en las ciudades a través de la participación de los ciudadanos. Para ello, propone un marco de análisis del proceso de toma de decisiones en los planes de regeneración urbana y su impacto en los resultados de los planes, tomando como caso de estudio la ciudad de Boston, que desde los años 1990 trata de convertirse en una “ciudad de los barrios”, fomentando la participación ciudadana al tiempo que se posiciona en la escena económica global. El análisis se centra en dos operaciones de regeneración iniciadas a finales de los años 1990. Por un lado, el caso de Jackson Square nos permite comprender el papel de la sociedad civil y el tercer sector en la regeneración de los barrios más desfavorecidos, en un claro ejemplo de urbanismo “desde abajo” (bottom-up planning). Por otro, la reconversión del frente marítimo de South Boston para la construcción del Distrito de Innovación nos acerca a las grandes operaciones de regeneración urbana con fines de estímulo económico, tradicionalmente vinculadas a los centros financieros (downtown) y dirigidas por las élites gubernamentales y económicas (la growth machine) a través de procesos más tecnocráticos (top-down planning). La metodología utilizada consiste en el análisis cualitativo de los procesos de toma de decisiones y la relación entre los agentes implicados, así como de la evaluación de la implementación de dichas decisiones y su influencia en el modelo urbano resultante. El análisis de los casos permite afirmar que la gobernanza de los procesos de regeneración urbana influye decisivamente en el resultado final de las intervenciones; sin embargo, la participación de la comunidad local en la toma de decisiones no es suficiente para que el resultado de la regeneración urbana contrarreste los efectos de la neoliberalización, especialmente si se limita a la fase de planeamiento y no se extiende a la fase de ejecución, y si no está apoyada por una movilización política de mayor alcance que asegure una acción pública redistributiva. Asimismo, puede afirmarse que los procesos de regeneración urbana suponen una redefinición del modelo de ciudad, dado que la elección de los espacios de intervención tiene consecuencias sobre el equilibrio territorial de la ciudad. Los resultados de esta investigación tienen implicaciones para la disciplina del planeamiento urbano. Por una parte, se confirma la vigencia del paradigma del “urbanismo negociado”, si bien bajo discursos de liderazgo público y sin apelación al protagonismo del sector privado. Por otra parte, la planificación colaborativa en un contexto de “responsabilización” de las organizaciones comunitarias puede desactivar la potencia política de la participación ciudadana y servir como “amortiguador” hacia el gobierno local. Asimismo, la sustitución del planeamiento general como instrumento de definición de la ciudad futura por una planificación oportunista basada en la actuación en áreas estratégicas que tiren del resto de la ciudad, no permite definir un modelo coherente y consensuado de la ciudad que se desea colectivamente, ni permite utilizar el planeamiento como mecanismo de redistribución. ABSTRACT In the past three decades, the dynamics of global economic restructuring have radically redefined the role of cities. The transition from keynesianism to neoliberalism has caused a shift in local governments’ urban policies, which have progressively abandoned the tasks of regulation and redistribution to focus on promoting economic growth and competitiveness. In this context, many critics have pointed out that urban regeneration has become a vehicle for extracting value from the city and is causing the expulsion of the most vulnerable citizens. However, regeneration of consolidated areas is also an opportunity to improve the living conditions of the resident population, and is a necessary policy to control the expansion of the city and reduce the need for transportation, thus promoting more sustainable cities. Assuming that the governance of urban regeneration processes is key to the final outcome of the plans and determines the resulting city model, the goal of this research is to verify whether urban regeneration is necessarily a value extraction mechanism or if it can improve the quality of life in cities through citizens’ participation. It proposes a framework for analysis of decision-making in urban regeneration processes and their impact on the results of the plans, taking as a case study the city of Boston, which since the 1990s is trying to become a "city of neighborhoods", encouraging citizen participation, while seeking to position itself in the global economic scene. The analysis focuses on two redevelopment plans initiated in the late 1990s. The Jackson Square case allows us to understand the role of civil society and the third sector in the regeneration of disadvantaged neighborhoods, in a clear example of bottom-up planning. On the contrary, the conversion of the South Boston waterfront to build the Innovation District takes us to the big redevelopment efforts with economic stimulus’ goals, traditionally linked to downtowns and led by government and economic elites (the local “growth machine”) through more technocratic processes (top-down planning). The research is based on a qualitative analysis of the processes of decision making and the relationship between those involved, as well as the evaluation of the implementation of those decisions and their influence on the resulting urban model. The analysis suggests that the governance of urban regeneration processes decisively influences the outcome of interventions; however, community engagement in the decision-making process is not enough for the result of the urban regeneration to counteract the effects of neoliberalization, especially if it is limited to the planning phase and does not extend to the implementation of the projects, and if it is not supported by a broader political mobilization to ensure a redistributive public action. Moreover, urban regeneration processes redefine the urban model, since the choice of intervention areas has important consequences for the territorial balance of the city. The results of this study have implications for the discipline of urban planning. On the one hand, it confirms the validity of the "negotiated planning" paradigm, albeit under public leadership discourse and without a direct appeal to the leadership role of the private sector. On the other hand, collaborative planning in a context of "responsibilization" of community based organizations can deactivate the political power of citizen participation and serve as a "buffer" towards the local government. Furthermore, the replacement of comprehensive planning, as a tool for defining the city's future, by an opportunistic planning based on intervention in strategic areas that are supposed to induce change in the rest of the city, does not allow a coherent and consensual urban model that is collectively desired, nor it allows to use planning as a redistribution mechanism.

Durante los últimos años, la construcción de grandes yates ha evolucionado hacia conceptos y diseños más complejos dónde se ha priorizado en muchas ocasiones la estética arquitectónica y exigencias de confort de los armadores y operadores dejando en segundo plano aspectos clave de seguridad. Diferentes Organismos Internacionales y las Sociedades de Clasificación han venido adaptando sus requisitos a la problemática específica de este tipo de buques, tratando de compatibilizar tendencias de diseño con exigencias de resistencia, integridad estructural, estanqueidad y seguridad entre otras. En la actualidad, la construcción de grandes yates con esloras incluso por encima de los 100 metros, el aumento del número de pasajeros por encima del límite tradicional de 12, las nuevas tendencias de ahorro energético y protección medioambiental que se están implantando en la industria en general y marítima en particular, plantean una serie de desafíos tanto a los diseñadores como a las Sociedades de Clasificación que deben avanzar en sus reglamentaciones para cubrir estos y otros aspectos. Son precisamente estos aspectos medioambientales, tradicionalmente relegados en la industria de grandes yates los que están ocupando en la actualidad un primer plano en los desarrollos de normativa de diferentes Organismos Internacionales y Nacionales. El impacto que estas nuevas normativas van a tener sobre el diseño de grandes yates a motor centra el desarrollo de esta Tesis. Hasta donde ha podido conocer el doctorando, esta es la primera vez que en una Tesis Doctoral se abordan los principales mecanismos que regulan el diseño y la construcción de grandes yates a motor, se estudian y analizan las regulaciones internacionales en materia de protección medioambiental y de eficiencia energética aplicables a los yates, se seleccionan y describen un conjunto de tecnologías maduras de carácter medioambiental, susceptibles de ser empleadas en yates y se determina los parámetros y aspectos del diseño a aplicar al proyecto de grandes yates a motor como resultado de la aplicación de estas tecnologías, analizados bajo la perspectiva de la Sociedad de Clasificación y de los Organismos Internacionales. La Tesis comienza con un análisis de la industria de construcción de grandes yates, la flota existente de grandes yates, la cartera actual de pedidos y la evolución esperada del mercado. Aquí se pone de manifiesto que a pesar de la crisis económica global de los últimos años, este mercado goza relativamente de buena salud y las previsiones son favorables, particularmente para el sector en Europa. A continuación se aborda el estado del arte del diseño de yate grande, sus peculiaridades, particularmente estructurales y de armamento, que le diferencian de otros tipos de buques y las tendencias en su diseño. Se pone de manifiesto cómo el proyecto de estos yates ha evolucionado hacia yates de gran tamaño y complejidad técnica, debido a la demanda y necesidades actuales y cómo ha influido en aspectos como la disposición estructural. Seguidamente se describen los principales mecanismos que regulan el diseño y construcción de grandes yates, particularmente el Código de Grandes Yates Comerciales de la Maritime & Coastguard Agency del Reino Unido, y las Reglas y Reglamentos de la Sociedad de Clasificación Lloyd’s Register para la Clasificación de yates; por ser ambas organizaciones las que lideran el Registro y la Clasificación respectivamente de este tipo de buques, objeto del estudio. El doctorando ejerce su actividad profesional como inspector de Lloyd’s Register en una oficina técnica de apoyo y evaluación de diseño, siendo especialista en grandes yates, lo que ha permitido exponer de primera mano el punto de vista de la Sociedad de Clasificación. En el siguiente Capítulo se describen las principales reglamentaciones internacionales de carácter medioambiental que afectan al diseño, construcción y operación de los yates, algunas de las cuales, como es el caso del Convenio Internacional para el Control y la Gestión del Agua de Lastre y Sedimentos de los buques (BWM 2004) aún no ha entrado en vigor a la fecha de terminación de esta Tesis. Seguidamente se realiza una selección de tecnologías desde el punto de vista de protección medioambiental y ahorro energético y su aplicación al diseño y construcción de grandes yates. Algunas de estas tecnologías son maduras y ya habían sido utilizadas con éxito en otros tipos de buques, pero su aplicación a los yates entraña ciertos desafíos que se describen en este Capítulo. A continuación se determinan y analizan los principales parámetros de diseño de los yates grandes a motor como consecuencia de las tecnologías estudiadas y se indican una serie de aspectos de diseño bajo la perspectiva de la Sociedad de Clasificación y de los Organismos Marítimos Internacionales. Finalmente se llega a una serie de conclusiones y se identifican futuras líneas de investigación en relación a las tecnologías descritas en este trabajo. ABSTRACT In recent years, the building of large yachts has evolved into more complex concepts and designs where often prioritized architectural aesthetics and comfort requirements of owners and operators leaving in the background key security aspects. Several international organizations and classification societies have been adapting their requirements to the specific problems of this type of vessel, trying to reconcile demands design trends with resistance, structural integrity, watertightness and safety among others. At present, the building of large yachts with lengths even above 100 meters, the increase in passenger numbers over the traditional limit of 12, new trends of energy saving and environmental protection are being implemented in the marine industry in particular, they pose a number of challenges to both designers and classification societies that should update and improve their regulations to cover these and other aspects. It is precisely these environmental issues, traditionally relegated to the large yacht industry, which are currently occupying center stage in the development of rules of different international and national bodies. The impact that these new standards will have on the design of large motor yachts focuses the development of this thesis. As far as it is known, this is the first time in a doctoral thesis the main mechanisms regulating the design and construction of large motor yachts are addressed, the international regulations on environmental protection and energy efficiency requirements for yachts are studied and analyzed, a set of mature environmental technologies, capable of being applied to yachts are selected and described, the parameters and design aspects to be applied to large yacht projects as a result of the application of these technologies are determined and analyzed from the perspective of the Classification Society and international organizations. The thesis begins with an analysis of the shipbuilding industry of large yachts, the existing fleet of large yachts, the current backlog and the expected market developments. Here it becomes clear that despite the global economic crisis of recent years, this market enjoys relatively good health and prospects are favorable, particularly for the sector in Europe. Then the state of the art of large yacht design, its peculiarities, particularly structural and outfitting, that differentiate it from other types of ships and trends in design is discussed. It shows how the project of these yachts has evolved to large yachts and technical complexity, due to the demand and needs and how it has influenced the structural arrangement aspects. Then the main mechanisms regulating the design and construction of large yachts, particularly the Large Commercial Yacht Code developed by the Maritime & Coastguard Agency (UK) and the Lloyd’s Register Rules & Regulations for the Classification of Special Service Craft including yachts are described; the two organizations to be leading the registration and classification respectively of such vessels under study. The doctoral student practices his profession as a senior specialist to Lloyd’s Register in a technical support office, dealing with the design assessment of large yachts, which allowed exposing firsthand view of the Classification Society. In the next chapter describes the main international environmental regulations, affecting the design, construction and operation of yachts, some of which, such as the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM 2004) has not yet entered into force at the date of completion of this thesis. Following is a selection of technologies from the point of view of environmental protection and energy saving and its application to design and construction of large yachts. Some of these technologies are mature and have already been used successfully in other ship types, but their application to yachts entails certain challenges that are described in this chapter. Then identifies and analyzes the main design parameters of large motor yachts as a result of the technologies studied and a number of design aspects are given from the perspective of Classification Society and international maritime organizations. Finally, a number of conclusions are exposed, and future research is identified in relation to the technologies described in this Thesis.

Este trabalho discute as transformações no modo de intervenção do Estado na produção do espaço urbano no capitalismo contemporâneo a partir de uma reflexão sobre as políticas de revitalização de centros urbanos e os conflitos de natureza distributiva relacionados a esses projetos. Situando-se no campo do direito econômico, o trabalho explora as relações entre a acumulação capitalista e os padrões de intervenção do Estado sobre o espaço urbano a partir de diferentes níveis de análise, articulando elementos teóricos, jurídico-institucionais e empíricos. O processo de reestruturação do capitalismo que se iniciou nos anos 1970 teve desdobramentos relevantes no campo da regulação urbanística, desencadeando mudanças que atingiram suas funções e formas, e que perpassam diversas escalas geográficas. A ordem social e econômica que se configurou no capitalismo contemporâneo, marcada pela difusão de uma agenda política neoliberal e pela emergência de um regime de acumulação com dominância financeira, tem seus desdobramentos específicos na escala das cidades. Nesse contexto, as políticas urbanas passaram a ser progressivamente norteadas por uma racionalidade pragmática e empresarial, fechando-se à influência de esferas democráticas e desviando-se da institucionalização de compromissos redistributivos. Essa mudança qualitativa é mediada por formas institucionais e arranjos regulatórios que não se limitam à escala urbana e ao direito urbanístico propriamente dito, perpassando normas que regulam o regime jurídico da propriedade imobiliária e suas conexões com a esfera financeira, os padrões de financiamento das políticas urbanas, entre outras. A partir de um estudo sobre o Projeto Porto Maravilha uma intervenção urbanística de grande porte, e amplamente conectada a fluxos econômicos globais, que está sendo implementada na cidade do Rio de Janeiro desde 2009 , desenvolvemos uma reflexão sobre alguns vetores de mudança no papel exercido pelo Estado nos processos de urbanização. Este trabalho apresenta duas hipóteses articuladas. A primeira é a de que os padrões de regulação urbanística que emergiram no capitalismo contemporâneo não são meros reflexos de transformações mais abrangentes, mas sim fatores constitutivos dessas mudanças. A segunda a é de que as políticas de revitalização de centros urbanos agem como vetores de aprofundamento das conexões entre dinâmicas locais e processos globais, e também como incubadoras de novos padrões de regulação urbanística.

As culturas da soja e milho são de grande importância econômica mundial e também para o Brasil, onde a área cultivada com essas duas culturas está estimada em 45.855.900 mil hectares, distribuídas em todos estados produtores conforme suas características. A estimativa da safra mundial de soja em 2015/16 apresentou uma redução na produção global da oleaginosa para 319,0 milhões de ton, volume 1,1 milhão de ton inferior ao levantamento de dezembro de 2015. Ainda assim, trata-se de um volume recorde. Para o milho, a produção global foi de 967,9 milhões de ton, com uma redução no volume de 5,9 milhões de ton em relação ao levantamento realizado em dezembro de 2015. Nessas duas culturas são comumente utilizadas bactérias fixadoras de nitrogênio (BFN), reduzindo ou até mesmo, eliminando a aplicação de adubos nitrogenados. Estudos apontam que a simbiose entre BFN e as culturas soja e milho pode ser otimizada mediante a coinoculação com rizobatérias promotoras de crescimento de plantas (RPCP). Apesar de promissora, o estudo da utilização de BFN em associação com RPCPs é incipiente no Brasil. Assim, o presente trabalho teve como objetivo monitorar, a partir da marcação bacteriana, a interação entre a linhagem de Burkholderia ambifaria (RZ2MS16), uma rizobactéria proveniente do guaranazeiro e previamente descrita como promotora de crescimento em soja e milho e linhagens das espécies Bradyrhizobium japonicum (SEMIA5079), Bradyrhizobium diazoefficiens (SEMIA5080) e Azospirillum brasilense (Ab-v5 e Ab-v6) que são comercialmente utilizadas como bioinoculantes nessas culturas respectivamente. Os efeitos sinergisticos da interação entre RZ2MS16 e bioinoculantes comercias foram avaliados em experimento de casa de vegetação. Também foi avaliado o efeito da coinoculação de bioinculantes com outra rizobactéria proveniente do guaranazeiro, Bacillus sp. (RZ2MS9). As linhagens foram inoculadas separadamente e coinoculadas, sendo melhores resultados observados com a coinoculação das linhagens. As linhagens marcadas com genes de fluorescência selecionadas para estudo de interação foram RZ2MS16, Ab-v5 e SEMIA5080, sendo essa interação observada por microscopia de fluorescência, com também pelo reisolamento das linhagens marcadas. As linhagens RZ2MS16:pNKGFP e Ab-v5: pWM1013 e SEMIA5080:pWM1013 colonizaram todos os nichos avaliados em milho e soja, respectivamente, sendo também caracterizadas como endofíticos. Assim se observa que estudos desta natureza são de grande importância para um melhor entendimento da interação entre bactéria planta e o efeito da coinoculação no melhor desenvolvimento de plantas comercialmente utilizadas.

Beyond free trade agreements governing cross-border commerce, the source of most global economic growth is attributed to business across interconnecting markets. Among the most attractive and complex markets, China stands out. Despite its appeal, American businesses are more likely to fail in China due to an overwhelming desire for an immediate return on investment while neglecting to consider or completely disregarding China's unique legal, ethical and cultural environment. This capstone project will give recommendations to help businesses succeed when entering China and avoid legal, ethical and cultural issues such as the ones that Google, Apple, and Yahoo experienced.

En medio de la actual crisis económica mundial, todas las instituciones de la sociedad están afectadas por la crisis moral, de manera que existe una evidente y preocupante contradicción entre ellas. Esta crisis moral implica la carencia de valores personales y ciudadanos, que afectan, significativamente, al desarrollo del individuo y a la convivencia social. Tratamos de verificar si hay indicios de ello en la realidad escolar con relación a la axiología curricular y su desarrollo. Para analizar la situación de la enseñanza-aprendizaje de los valores en la educación española, hemos aplicado una encuesta a 1320 profesores de educación secundaria, con el fin de averiguar los objetivos, los tipos de valores y las habilidades personales y sociales, que desarrollan en el aula. La situación nos indica que son necesarios nuevos enfoques de educación en valores, que se adapten a estos tiempos. La formación axiológica debe estar incorporada en todos los ámbitos del conocimiento y ha de ir a la par que la formación de la inteligencia. El binomio actividad intelectual-actividad moral ha de formar un todo insociable. En esta propuesta, reflexionamos en torno a la aplicación de un nuevo paradigma axiológico que se separe del racionalismo mecanicista, y que se oriente a una educación personal holística, sistemática, interdisciplinaria y transversal a todo el currículo educativo.

En este trabajo se analiza cómo el tiempo de trayecto y las características de los mercados laborales locales influyen en el desajuste puesto de trabajo- nivel educativo del individuo, basado en la hipótesis de que los individuos que tienen un mayor tiempo de trayecto al trabajo y mejores condiciones en mercado laboral se asocian a una menor incidencia de la sobreeducación. La sobreeducación afecta a 17 % de los trabajadores en España, y se eleva al 22,4 % para los trabajadores menores de 35 años. El análisis se basa en los datos individuales de los trabajadores españoles que se refiere al período inicial de la crisis económica mundial (2007-2010). La variable dependiente, desajuste educativo-puesto se mide mediante el método subjetivo, basado en las respuestas del individuo a la pregunta de cómo ajusta su nivel de educación a las necesidades del trabajo que actualmente ocupan. La variable de interés son: (a) el tiempo de trayecto, es decir, el tiempo que tarda el individuo en llegar a su trabajo, y (b) dos variables que tienen en cuenta de las condiciones del mercado local: la tasa regional de desempleo (esta variable se refieren a la división territorial de España a nivel NUTS 2 y desglose por sexo y nivel de educación de cada Comunidad Autónoma sobre la base de las cifras medias anuales de la Encuesta de Población Activa española (EPA) para el período 2007-2010) y el tamaño del municipio. Se incluyen las variables de control habituales relativas al puesto de trabajo y variables dummy de los años de la muestra. Los resultados sugieren que las difíciles condiciones de trabajo regionales en términos de altas tasas de desempleo pueden actuar contra el efecto hipotético de la movilidad en la reducción del desajuste educativo, por lo tanto, se obtiene a una conclusión opuesta a la planteada en algunos trabajos anteriores.

[Introduction.] It is generally believed that while the principle of the autonomy of the EU legal order, in the sense of constitutional and institutional autonomy that is to say what concerns the autonomous decision-making of the EU, has been clearly strengthened by the most recent jurisprudence of the Court of Justice (eg. Moxplant3, Intertanko or the Kadi/Al Baraakat judgements or the Opinion 1/2009 of the CJEU etc.) as well as, in my opinion, in many aspects by the Treaty of Lisbon, it is still valid to add that the principle of a favourable approach, stemming from the Court jurisprudence, for the enhanced openness of the EU legal order to international law has remained equally important for the EU4. On the other hand, it should be also seen that in a globalized world, and following the increased role of the EU as an international actor, its indispensable and crucial role concerning the creation of world (legal) order in many policy fields ( for example let's think about the G20 issues, the global economic and financial crisis, the role of the EU in promoting and protecting human rights worldwide, the implementation of the multilateral or regional conventional law, developed in the framework the UN (e.g. in the field of agriculture or environment etc) or what concerns the Kyoto process on climate change or the conservation of marine biological resources at international level etc), it seems reasonable and justified to submit that the influence, for example, of the law-making activities of the main stakeholder international organizations in the mentioned policy-areas on the EU (especially on the development of its constantly evolving legal order) or vice-versa the influence of the EU law-making practice on these international organizations is significant, in many aspects mutually interdependent and more and more remarkable. This tendency of the 21st century doesn't mean, however, in my view, that the notion of the autonomy of the EU legal order would have been weakened by this increasing interaction between international law and EU law over the passed years. This contribution is going to demonstrate and prove these departuring points by giving some concrete examples from the most recent practice of the Council (all occuring either in the second half of 2009 or after the entry into force of the Lisbon Treaty), and which relate to two very important policy areas in the EU, namely the protection of human rights and the Common Fishery Policy.

In May 2013, the European Commission received a mandate from the European Council to “to present an analysis of the composition and drivers of energy prices and costs in Member States, with a particular focus on the impact on households, SMEs and energy intensive industries, and looking more widely at the EU's competitiveness vis-à-vis its global economic counterparts”. Following such mandate and in view of the preparation by the Commission of a Communication and a Staff Working Document, DG Enterprise and Industry commissioned CEPS to carry out a set of studies aimed at providing well-grounded evidence about the evolution and composition of energy prices and costs at plant level within individual industry sectors. A team of CEPS researchers conducted the research, led by Christian Egenhofer and Lorna Schrefler. Vasileios Rizos served as Project Coordinator. Other CEPS researchers contributing to the project included: Fabio Genoese, Andrea Renda, Andrei Marcu, Julian Wieczorkiewicz, Susanna Roth, Federico Infelise, Giacomo Luchetta, Lorenzo Colantoni, Wijnand Stoefs, Jacopo Timini and Felice Simonelli. In addition to an introductory report entitled “About the Study and Cross-Sectoral Analysis”, CEPS prepared five sectoral case studies: two on ceramics (wall and floor tiles and bricks and roof tiles), two on chemicals (ammonia and chlorine) and one on flat glass. Each of these six studies has been consolidated in this single volume for free downloading on the CEPS website. The specific objective was to complement information already available at macro level with a bottom-up perspective on the operating conditions that industry stakeholders need to deal with, in terms of energy prices and costs. The approach chosen was based on case studies for a selected set (sub-)sectors amongst energy-intensive industries. A standard questionnaire was circulated and respondents were sampled according to specified criteria. Data and information collected were finally presented in a structured format in order to guarantee comparability of results between the different (sub-)sectors analysed. The complete set of files can also be downloaded from the European Commission’s website: http://ec.europa.eu/enterprise/newsroom/cf/itemdetail.cfm?item_id=7238&lang=en&title=Study-on-composition-and-drivers-of-energy-prices-and-costs-in-energy-intnsive-industries The results of the studies were presented at a CEPS Conference held on February 26th along with additional evidence from other similar studies.
