Efectos territoriales de las denominaciones de origen protegidas de aceite de oliva en España

La implementación de indicaciones geográficas, generan distintos efectos socio-económicos, tecnológicos y ambientales, no sólo a nivel de los productores directamente involucrados, sino también en el marco del sistema agroalimentario local (SIAL). Entre estos últimos, se destaca la organización colectiva de los productores y el desarrollo de una gobernanza, a partir del conjunto de actividades desarrolladas por el Consejo Regulador (CR), en torno al control de calidad y la promoción del producto. El concepto de gobernanza territorial implica llevar a cabo procesos de organización colectiva en red en los que tienen lugar procesos de coordinación multi-nivel entre los agentes, las empresas y las instituciones locales, en un contexto de asimetría en la información y de la existencia de numerosos decisores. El objetivo de esta Tesis Doctoral es realizar un aporte metodológico para el estudio de la gobernanza territorial en sistemas agroalimentarios localizados, a partir de la construcción de indicadores (de calidad, innovación, efectos económicos y prácticas ambientales) y el análisis de las redes de colaboración en materia de difusión del conocimiento e innovaciones técnicas, organizativas y comerciales en la Comarca de Sierra Mágina. Para responder el objetivo se aplica análisis de redes sociales y se construyen indicadores sintéticos para valorizar los efectos. Se realizan encuestas a la totalidad de almazaras presentes en la Comarca de Sierra Mágina, tanto a las que poseen el signo de calidad como a las que no cuentan con dicha marca territorial y entrevistas a testigos privilegiados. En las mismas se consulta sobre las actividades y proyectos que realizan en forma conjunta con otras almazaras e instituciones, así como los actores o referentes a quiénes consultan en temas relacionados con la calidad en la producción olivícola y la obtención de aceite, así como aquellos actores a quienes consultan en aspectos referidos a la Comercialización y gestión. A partir de la información recabada, se obtienen cuatro indicadores sintéticos de efectos de la implantación de una DOP en las almazaras adheridas, referidos a la adopción de innovaciones productivas y organizativas, a la calidad en producto y procesos, a las rentas de diferenciación y a las prácticas ambientales. Asimismo se generan las matrices bi-narias y valuadas para las redes de colaboración en la difusión del conocimiento y se calculan los indicadores particulares. Esto nos permite estudiar las características de las redes que se generan (tamaño, conectividad), el papel del CR en la gobernanza territorial y de otras instituciones del medio, así como identificar actores centrales y grupos en el proceso de difusión de conocimientos. Los resultados muestran que los SIAL pueden beneficiarse de la organización interprofesional y de cooperación interinstitucional a escala local que se producen tras la implantación de una DOP. Se desarrolla un proceso de articulación y un fuerte intercambio de conocimientos entre actores ligados al propio proceso de control de la calidad diferencial. Pero, junto con ello, se desarrollan actividades de formación y de promoción del patrimonio comarcal y se consolidan redes locales de innovación y colaboración mutua en distintas actividades, tanto entre actores de la propia cadena de producción, como entre éstos y las instituciones del medio. Estas actividades, junto con la presencia de un entramado institucional denso, permiten el desarrollo de una gobernanza territorial alrededor del sistema agroalimentario del aceite de oliva. ABSTRACT The implementation of geographical indications has different socio-economic, technological and environmental effects not only for the producers involved but also for the local agro food system (LAFS). Among the latter, we can highlight the collective organization of producers and the development of territorial governance through a series of tasks developed by the Regulatory Board (RB) as regards quality control and product marketing. The concept of territorial governance involves processes of collective organization in networks, where processes of multi-level coordination among agents, enterprises and local institutions take place within a context of asymmetry of information and numerous decision makers. The objective of this Doctoral Thesis is to contribute with methodological tools for the study of territorial governance in local agro food systems by constructing indicators (of quality, innovation, economic effects and environmental practices) and by analyzing networks of collaboration in terms of dissemination of technical, organizational and commercial innovation and knowledge in Comarca de Sierra Mágina. To achieve that objective, social network analysis is applied and synthetic indicators are elaborated to valorize the effects. Interviews to key actors and surveys to every oil mill in Comarca de Sierra Mágina are carried out, not only in those oil mills that host a label of quality but also in the ones that do not hold it. These interviews inquire about tasks and projects performed together with other oil mills and institutions and about actors or referents consulted in topics related to quality in olive production and oil extraction as well as in management and marketing. From all the information collected, four synthetic indicators of the effects of establishing Protected Designations of Origen (PDOs) in the associate oil mills are obtained, in terms of adoption of productive and organizational innovations, process and product quality, income differentiation and environmental practices. In the same way, binary and valorized matrixes are generated for those networks collaborating in the dissemination of knowledge and specific indicators are calculated. This allows to study networks (size, connectivity), the role of RB in territorial governance and other institutions involved and to identify main actors and groups in the process of knowledge dissemination. The results show that the LAFS can benefit from inter-professional organizations and inter- institutional cooperation at local levels by implementing PDOs. A process of articulation and strong exchange of knowledge is developed among those actors involved in controlling differential quality. But, at the same time, activities for the formation and promotion of the “comarca” patrimony are developed and local networks of innovation and mutual collaboration are built for different activities, not only among actors in the production process itself, but between these actors and local institutions as well. These tasks, together with the existence of a dense spatial entrepreneurial network, allow the development of territorial governance on the olive oil agro food system.

La construcción del espacio litoral : el caso de la costa de Cartagena

El litoral ha constituido a lo largo de la historia una importante fuente de recursos económicos además de un punto estratégico para la defensa del territorio. El comercio, la pesca o la industria de la sal han propiciado la formación de poblaciones y ciudades al borde del mar. La costa funcionó como un ámbito defensivo, peligroso e insalubre durante siglos donde el mar modulaba el frente costero sin grandes interacciones con un entorno prácticamente deshabitado. A mediados del siglo XIX, las innovaciones técnicas y la pacificación definitiva del Mediterráneo permiten poner en valor sus características naturales y de oportunidad. Sin perder del todo su valor defensivo, el litoral resurge como recurso productivo y como lugar de ocio y disfrute de la población. El valor estratégico de la costa quedará también reflejado en el marco normativo. El derecho civil moderno recuperará el concepto de Dominio público Marítimo Terrestre a través de la Ley de Aguas de 1866 que regulará también los usos y las limitaciones en la propiedad privada litoral. Desde ese momento, las transformaciones económicas, sociales, jurídicas y ambientales van a provocar un cambio significativo en la relación entre la sociedad y la costa que dará paso a la construcción del espacio litoral que hemos heredado. Desde la triple perspectiva del litoral como sistema físico ambiental, sistema económico, productivo y cultural, y sistema administrativo y legal, el principal objetivo de la tesis será reconstruir el proceso de transformación del litoral consecuencia de la evolución en la forma de producción del espacio, de área defensiva a recurso productivo, y desde mediados del siglo XIX hasta principios del siglo XXI. Sin embargo, la construcción del litoral no ha sido homogénea ni constante a lo largo del tiempo. Ha estado sujeta a los distintos vaivenes económicos y sociales pero también a los cambios en el modelo territorial definido por el marco legal vigente, así como a los reajustes del propio sistema físico. Como instrumento sociopolítico, el marco legal regula las presiones del sistema económico sobre el medio, apostando por una visión frente a otra, y posibilitando el grado de transformación final. Así, el conocimiento sobre el territorio en el que se interviene y la definición del modelo de litoral por parte de los poderes públicos irán configurando el espacio físico, económico y social desarrollado en la costa. Para la reconstrucción del proceso de construcción del litoral, la tesis define cuatro fases diferentes y aplica las hipótesis y la metodología a la costa de Cartagena. Se presenta gráficamente la evolución en los tres sistemas en cada una de las fases, y se recompone el relato histórico a través de los hitos más relevantes para el proceso. En cada una de las fases, el nuevo modelo intentará dar respuesta a todo aquello que no funcionó o se quedó a medias en el periodo anterior. Las crisis económicas provocan la ralentización de la actividad productiva y, consecuentemente, de las transformaciones en el territorio. Servirán para establecer, en principio, un cambio de paradigma en la lectura y gestión del litoral que acabará traduciéndose en un nuevo texto legislativo en materia de costas (1969, 1988 y 2013). La reforma de la normativa responde a una nueva forma de entender, ordenar, gestionar e intervenir en el territorio, donde se modulan las pautas pero también la intensidad en la intervención. Pero nace condicionada por el litoral heredado: los derechos generados durante la vigencia del marco legal anterior; el modelo económico y sus presiones y expectativas sobre el litoral; y el medio físico en el que se acumulan los procesos de degradación no resueltos y los nuevos riesgos. Así, las conclusiones de la tesis ponen de manifiesto la necesidad de una visión compleja e integral sobre el litoral, en la que el urbanismo y la ordenación del territorio serán fundamentales para afrontar los nuevos retos en su construcción a futuro. ABSTRACT The littoral has been throughout history an important source of economic resources and a strategic point for the defense of territory. Trade, fishing or salt industry have led to the formation of towns and cities on the edge of the sea. The coast served as a defensive, dangerous and unhealthy place where the sea modulated for centuries the waterfront without major interactions with a virtually uninhabited environment. In the mid-nineteenth century, technical innovations and the final pacification of the Mediterranean allowed to value its natural features and opportunities. Without entirely losing its defensive value, the coast emerges as a productive resource and as a place of leisure and enjoyment of people. The strategic value of the coast will also be reflected in the legal framework. The concept of maritime-terrestrial public domain will be recovered by the modern civil law and the law of waters of 1866 governs the uses and limitations of private ownership of the coast. Since then, the economic, social, legal and environmental changes will to cause a significant change in the relationship between society and the coast that will give way to the construction of littoral space inherited. From the triple perspective of the littoral as a physical environmental system, an economic, productive and cultural system, and an administrative and legal system, the main objective of the thesis is to rebuild its process of transformation, as a result of the evolution in the way that space is produced, from defensive zone to productive resource, and from the middle of the nineteenth century until the beginning of the twenty-first century. However, the construction of the coast has not been uniform nor constant over time. It has been subject to different economic and social fluctuations and also to changes in the territorial model defined by the legal framework in force, as well as to readjustments of the physical system itself. As socio-political instrument, the legal framework regulates the pressure of the economic system on the environment, it bets on a vision over another and facilitates the final degree of transformation. Thus, the knowledge on the territory that is being intervened and the definition of the model of shoreline by public authorities will configure the physical, economic and social space developed on the coast. For the reconstruction of the littoral building process, the thesis defines four different phases and applies the hypothesis and methodology to the coast of Cartagena. It introduces graphically the evolution of the three systems in each of the phases and it recomposes the historical account through of the most important milestones for the process. In each phase, the new model will attempt to answer everything that did not work or was half in the previous period. Economic crises cause a slowdown in productive activity and, consequently, in the changes of territory. They serve to establish, in principle, a paradigm shift for reading and managing the littoral, eventually resulting in new legal texts on coasts matter (1969, 1988 and 2013). The reform of legislation responds to a new way for understanding, arranging, managing and intervening on the territory, where the guidelines and also the intervention intensity are modulated. But it is born conditioned by the inherited coast: the rights generated under previous legal framework; the economic model and its pressures and expectations on the littoral; and the physical environment which accumulates degradation processes unresolved and new risks. Thus, the thesis conclusions highlight the need for a complex and comprehensive view on the littoral, where urban planning and land-use planning will be key to meet the future challenges in its construction.

On the controllability of distributed systems

To “control” a system is to make it behave (hopefully) according to our “wishes,” in a way compatible with safety and ethics, at the least possible cost. The systems considered here are distributed—i.e., governed (modeled) by partial differential equations (PDEs) of evolution. Our “wish” is to drive the system in a given time, by an adequate choice of the controls, from a given initial state to a final given state, which is the target. If this can be achieved (respectively, if we can reach any “neighborhood” of the target) the system, with the controls at our disposal, is exactly (respectively, approximately) controllable. A very general (and fuzzy) idea is that the more a system is “unstable” (chaotic, turbulent) the “simplest,” or the “cheapest,” it is to achieve exact or approximate controllability. When the PDEs are the Navier–Stokes equations, it leads to conjectures, which are presented and explained. Recent results, reported in this expository paper, essentially prove the conjectures in two space dimensions. In three space dimensions, a large number of new questions arise, some new results support (without proving) the conjectures, such as generic controllability and cases of decrease of cost of control when the instability increases. Short comments are made on models arising in climatology, thermoelasticity, non-Newtonian fluids, and molecular chemistry. The Introduction of the paper and the first part of all sections are not technical. Many open questions are mentioned in the text.

National policies for technical change: Where are the increasing returns to economic research?

Improvements over the past 30 years in statistical data, analysis, and related theory have strengthened the basis for science and technology policy by confirming the importance of technical change in national economic performance. But two important features of scientific and technological activities in the Organization for Economic Cooperation and Development countries are still not addressed adequately in mainstream economics: (i) the justification of public funding for basic research and (ii) persistent international differences in investment in research and development and related activities. In addition, one major gap is now emerging in our systems of empirical measurement—the development of software technology, especially in the service sector. There are therefore dangers of diminishing returns to the usefulness of economic research, which continues to rely completely on established theory and established statistical sources. Alternative propositions that deserve serious consideration are: (i) the economic usefulness of basic research is in the provision of (mainly tacit) skills rather than codified and applicable information; (ii) in developing and exploiting technological opportunities, institutional competencies are just as important as the incentive structures that they face; and (iii) software technology developed in traditional service sectors may now be a more important locus of technical change than software technology developed in “high-tech” manufacturing.

An Empirical Comparison of Reuse in Embedded and Nonembedded Systems

High-quality software, delivered on time and budget, constitutes a critical part of most products and services in modern society. Our government has invested billions of dollars to develop software assets, often to redevelop the same capability many times. Recognizing the waste involved in redeveloping these assets, in 1992 the Department of Defense issued the Software Reuse Initiative. The vision of the Software Reuse Initiative was "To drive the DoD software community from its current "re-invent the software" cycle to a process-driven, domain-specific, architecture-centric, library-based way of constructing software.'' Twenty years after issuing this initiative, there is evidence of this vision beginning to be realized in nonembedded systems. However, virtually every large embedded system undertaken has incurred large cost and schedule overruns. Investigations into the root cause of these overruns implicates reuse. Why are we seeing improvements in the outcomes of these large scale nonembedded systems and worse outcomes in embedded systems? This question is the foundation for this research. The experiences of the Aerospace industry have led to a number of questions about reuse and how the industry is employing reuse in embedded systems. For example, does reuse in embedded systems yield the same outcomes as in nonembedded systems? Are the outcomes positive? If the outcomes are different, it may indicate that embedded systems should not use data from nonembedded systems for estimation. Are embedded systems using the same development approaches as nonembedded systems? Does the development approach make a difference? If embedded systems develop software differently from nonembedded systems, it may mean that the same processes do not apply to both types of systems. What about the reuse of different artifacts? Perhaps there are certain artifacts that, when reused, contribute more or are more difficult to use in embedded systems. Finally, what are the success factors and obstacles to reuse? Are they the same in embedded systems as in nonembedded systems? The research in this dissertation is comprised of a series of empirical studies using professionals in the aerospace and defense industry as its subjects. The main focus has been to investigate the reuse practices of embedded systems professionals and nonembedded systems professionals and compare the methods and artifacts used against the outcomes. The research has followed a combined qualitative and quantitative design approach. The qualitative data were collected by surveying software and systems engineers, interviewing senior developers, and reading numerous documents and other studies. Quantitative data were derived from converting survey and interview respondents' answers into coding that could be counted and measured. From the search of existing empirical literature, we learned that reuse in embedded systems are in fact significantly different from nonembedded systems, particularly in effort in model based development approach and quality where the development approach was not specified. The questionnaire showed differences in the development approach used in embedded projects from nonembedded projects, in particular, embedded systems were significantly more likely to use a heritage/legacy development approach. There was also a difference in the artifacts used, with embedded systems more likely to reuse hardware, test products, and test clusters. Nearly all the projects reported using code, but the questionnaire showed that the reuse of code brought mixed results. One of the differences expressed by the respondents to the questionnaire was the difficulty in reuse of code for embedded systems when the platform changed. The semistructured interviews were performed to tell us why the phenomena in the review of literature and the questionnaire were observed. We asked respected industry professionals, such as senior fellows, fellows and distinguished members of technical staff, about their experiences with reuse. We learned that many embedded systems used heritage/legacy development approaches because their systems had been around for many years, before models and modeling tools became available. We learned that reuse of code is beneficial primarily when the code does not require modification, but, especially in embedded systems, once it has to be changed, reuse of code yields few benefits. Finally, while platform independence is a goal for many in nonembedded systems, it is certainly not a goal for the embedded systems professionals and in many cases it is a detriment. However, both embedded and nonembedded systems professionals endorsed the idea of platform standardization. Finally, we conclude that while reuse in embedded systems and nonembedded systems is different today, they are converging. As heritage embedded systems are phased out, models become more robust and platforms are standardized, reuse in embedded systems will become more like nonembedded systems.

A three-stage DEA model to evaluate learning-teaching technical efficiency: Key performance indicators and contextual variables

This study evaluates the technical efficiency of the learning-teaching process in higher education using a three-stage procedure that offers advances in comparison to previous studies and improves the quality of the results. First, it utilizes a multiple stage Data Envelopment Analysis (DEA) with contextual variables. Second, the levels of super efficiency are calculated in order to prioritize the efficiency units. And finally, through sensitivity analysis, the contribution of each key performance indicator (KPI) is established with respect to the efficiency levels without omission of variables. The analytical data was collected from a survey completed by 633 tourism students during the 2011/12, 2012/13 and 2013/14 academic course years. The results suggest that level of satisfaction with the course, diversity of materials and satisfaction with the teacher were the most important factors affecting teaching performance. Furthermore, the effect of the contextual variables was found to be significant.

R&D, Spillovers, Innovation Systems and the Genesis of Regional Growth in Europe. Bruges European Economic Research (BEER) Papers 5/October 2006

Research on the impact of innovation on regional economic performance in Europe has fundamentally followed three approaches: a) the analysis of the link between investment in R&D, patents, and economic growth; b) the study of the existence and efficiency of regional innovation systems; and c) the examination of geographical diffusion of regional knowledge spillovers. These complementary approaches have, however, rarely been combined. Important operational and methodological barriers have thwarted any potential cross-fertilization. In this paper, we try to fill this gap in the literature by combining in one model R&D, spillovers, and innovation systems approaches. A multiple regression analysis is conducted for all regions of the EU-25, including measures of R&D investment, proxies for regional innovation systems, and knowledge and socio-economic spillovers. This approach allows us to discriminate between the influence of internal factors and external knowledge and institutional flows on regional economic growth. The empirical results highlight how the interaction between local and external research with local and external socioeconomic and institutional conditions determines the potential of every region in order to maximise its innovation capacity. They also indicate the importance of proximity for the transmission of economically productive knowledge, as spillovers show strong distance decay effects. In the EU-25 context, only the innovative efforts pursued within a 180 minute travel radius have a positive and significant impact on regional growth performance.

Determinants of Financial Development across the Mediterranean. MEDPRO Technical Report No. 29/February 2013

Casual observation shows that that the financial systems in the southern and eastern Mediterranean are unable (or unwilling) to divert the financial resources that are available to them as funding opportunities to private enterprises. Using a sample of both northern and southern Mediterranean countries for the years 1985 to 2009, this study empirically assesses the reasons underlying such conditions. The results show that strong legal institutions, good democratic governance and adequate implementation of financial reforms can have a substantial positive impact on financial development only when they are present collectively. Moreover, inflation appears to undermine banking development, but less so when the capital account is open. Government debt growth appears to weaken credit growth, which confirms that public debt ‘crowds out’ private debt. Lastly, capital inflows appear to primarily have an income effect, increasing income and thereby national savings, and thus increasing the availability of credit.

Egypt: Changes and Challenges of Political Transition. MEDPRO Technical Report No. 4/May 2011

Hosni Mubarak’s regime and its power system enjoyed remarkable stability for over 30 years. On 11 February 2011, after 18 days of mass protests, the Egyptian president was forced to step down, revealing the unsustainability of the political and economic system that had ensured his continuity for so long. While the revolution of January 25th led to a major success – the fall of Hosni Mubarak – Egypt’s political future is still opaque and exposed to a number of risks. This paper first highlights the factors underpinning the former stability of Mubarak’s regime; it then assesses the causes of its underlying unsustainability, leading to the anti-government popular mobilisation in January-February 2011 and the removal of Mubarak; finally the paper evaluates the prospects for a genuine democratic transition in Egypt, by looking at the main political and socio-economic challenges facing the country.

Tunisia: Changes and Challenges of Political Transition. MEDPRO Technical Report No. 3/May 2011

For 23 years, a combination of harsh repression and impressive socio-economic development in Tunisia ensured a certain level of stability of Ben Ali’s regime. However, on 14 January 2011, after several weeks of anti-government protests, the President fled the country, revealing the fallacy of the ‘Tunisian model’. While the departure of Ben Ali is an important step towards Tunisia’s political change, the fate of its democratic transition remains uncertain. In light of these changes and challenges, this paper first assesses the factors underpinning the former stability of Ben Ali’s regime; it then investigates the causes of its underlying unsustainability, culminating in the anti-government popular uprising in December 2010-January 2011 and the removal of Ben Ali; finally the paper evaluates the prospects for a real democratic transition in Tunisia, by highlighting the main political and socio-economic challenges that confront the country

Domain Globalization: Using Languages to Support Technical and Social Coordination

When a project is realized in a globalized environment, multiple stakeholders from different organizations work on the same system. Depending on the stakeholders and their organizations, various (possibly overlapping) concerns are raised in the development of the system. In this context a Domain Specific Language (DSL) supports the work of a group of stakeholders who are responsible for addressing a specific set of concerns. This chapter identifies the open challenges arising from the coordination of globalized domain-specific languages. We identify two types of coordination: technical coordination and social coordination. After presenting an overview of the current state of the art, we discuss first the open challenges arising from the composition of multiple DSLs, and then the open challenges associated to the collaboration in a globalized environment.
