The Utility of the Human Security Agenda for Policy-makers

The idea of “human security” is gaining attention among policy-makers and security analysts. Little scholarly attention has been given to the questions of why states accept (or reject) a human security agenda or how such an agenda is incorporated into policy practices. The article suggests that a human security approach is most likely to be applied when both humanitarian and national interests combine. Yet when states or organisations adopt a human security approach, they often misjudge the complex and long-term commitment required of such an approach. There is also the potential for such an agenda to be manipulated to justify questionable courses of action. These issues frame an analysis of six recent case studies.

A dimensão urbana da arquitetura : ambientes de transição

The present work aims to discuss the urban dimension of architecture and to investigate the role of the architectural spaces in the quality of life in between buildings and their environments. It investigates the transitional spaces between building and thoroughfare; building, thoroughfare and built environments located on the ground level of the buildings, and the potential they have to modify (individually or in groups) the environment where they are. For that, the research studies aspects of the architecture that urban buildings (individually or in groups) have and the inference of the morphology, building type and urban environment quality within the extended context of the Brazilian contemporary city. The analysis of the relation between building, thoroughfare and adjacent surroundings will be performed by the lights of, the evolution they have suffered since European urban spatial interventions that took place in the 19th Century; the morphological rupture on the traditional modern city of the 20th Century; the Brazilian experience focused on edifices, by showing analysis of a group of buildings, in their majority, iconic examples of Brazilian architecture from the 1930s onwards; and finally by an extensive investigation on the micro areas that have been selected in the Camburi region, in the city of Vitória-ES, focused on the characteristics of their architectural complex. As a preliminary conclusion, it can be stated that architecture cannot determine the quality in urban life and in its environments by itself, but because of its architectural and urban configuration of space, it may contribute to quality of environment in its surroundings

Competitiveness of tourist destinations: the study of 65 key destinations for the development of regional tourism

Tourism has reached world importance in the economy. The competition in tourism has intensified between destinations, whether the destinations are cities, regions or countries. In this sense, the evaluation of the tourism competitiveness of these destinations may be helpful in planning and prioritizing actions that will benefit the industry. This article discusses the concept of competitiveness by the multidimensional view of performance, efficiency and unit analysis. Using the theoretical framework lifted, this article shows the 'Study on the competitiveness of the 65 destinations inducers of regional tourism development' prepared by the Tourism Ministry, the Brazilian Support Service to Micro and Small Enterprises (Sebrae) and Getulio Vargas Foundation (FGV), its assumptions that guided this study as well its methodological aspects. Based on this methodology, it was carried out a diagnosis of these 65 destinations selected by the Brazilian Ministry of Tourism to be inducers of tourism in their respective regions. The result of competitiveness reached by these 65 inductors destinations is presented in this article, providing a map of the level of competitiveness of tourism in Brazil.

A incubação das micro, pequenas e médias empresas (MPMEs) em Portugal : uma discussão sobre custos de transacção, dimensão competitiva e a cadeia de valor

RESUMO: Este trabalho tem por objectivo discutir as formas como as incubadoras de empresas contribuem para a criação da cadeia de valores de Micros, Pequenas e Médias Empresas (MPMEs) permitindo a redução dos seus custos de transacção. Para melhor compreender a forma como se reduzem os custos de transacção é importante conhecer os pressupostos comportamentais que provocam a existência de tais custos: a racionalidade limitada, porque a nossa forma de pensar tem limitações; e o oportunismo, porque há pessoas com comportamentos desonestos envolvidas no negócio. O verdadeiro poder explicativo da teoria dos custos de transacção está, no entanto, na análise de três variáveis que determinam se esses custos serão mais baixos numa estrutura hierárquica ou num mercado. Estas três variáveis são: a especificidade de activos - se uma transacção envolve ou não activos específicos à actividade da empresa; a incerteza - qual o grau de incerteza em encontrar um produto ou serviço externo à empresa; e a frequência - e se um bem ou serviço é frequentemente utilizado ou não. As incubadoras de empresas são actualmente consideradas como uma iniciativa essencial ao desenvolvimento socioeconómico regional, e nacional. Estas instituições contribuem para corrigir ineficiências no mercado, conferindo às empresas uma capacidade de inovação tecnológica que garante empregos e a criação de riquezas, aumentando o bem-estar da sociedade. O sucesso da sua actuação resume-se à capacidade para gerar dimensões virtuais que contribuem para a cadeia de valores, permitindo as MPMEs, a redução dos seus custos de transacção. ABSTRACT: This work aims to discuss the relevant forms how incubators contribute to the value chain of a in micro, small and medium enterprises (MSME´s) reducing their transaction costs. To better understand how transaction costs can be reduced one must recognize the behavioral assumptions that are behind there existence; bounded rationality - because our way of thinking has limitations and opportunism - because there are dishonest people involved in the business. The true cost theory´s explanatory power comes from the analyses of the three variables that determine whether those costs will be lower in a hierarchical structure or a market structure. These three variables are: specificity of assets - if the transaction involves or not specific assets in for the firm´s activity; the uncertainty - what is the degree of uncertainty in finding a product or service external to the firm; and the frequency - what is the frequency of the good or service use. Business incubators are currently regarded as a key initiative for the national or regional economic development. The institutions contribute to correct market inefficiencies, improving the capacity of firms to produce technological innovations that guaranty jobs and wealth creation increasing welfare. The success of this all boils down to the capacity to create virtual dimensions that contributes to the MSME´s value chain reducing transaction costs.

Micro-generation Evaluation of the Zero Emissions Technologies in the Portuguese Market

Micro-generation is the small scale production of heat and/or electricity from a low carbon source and can be a powerful driver for carbon reduction, behavior change, security of supply and economic value. The energy conversion technologies can include photovoltaic panels, micro combined heat and power, micro wind, heat pumps, solar thermal systems, fuel cells and micro hydro schemes. In this paper, a small research of the availability of the conversion apparatus and the prices for the micro wind turbines and photovoltaic systems is made and a comparison between these two technologies is performed in terms of the availability of the resource and costs. An analysis of the new legal framework published in Portugal is done to realize if the incentives to individualspsila investment in sustainable and local energy production is worth for their point of view. An economic evaluation for these alternatives, accounting with the governmentpsilas incentives should lead, in most cases, into attractive return rates for the investment. Apart from the attractiveness of the investment there are though other aspects that should be taken into account and those are the benefits that these choices have to us all. The idea is that micro-generation will not only make a significant direct contribution to carbon reduction targets, it will also trigger a multiplier effect in behavior change by engaging hearts and minds, and providing more efficient use of energy by householders. The diversified profile of power generation by micro-generators, both in terms of location and timing, should reduce the impact of intermittency or plant failures with significant gains for security of supply.

Maritime Security in the Gulf of Guinea: Issues and Solutions for the 21st Century

A producer of 5.4 M bbl/d, totalling almost half of the consumption of the entire European Union, the Gulf of Guinea is a fundamental lifeline and maritime link between Europe, the Americas and Africa. Geographically positioned as a staging post for transit originating in Latin America and coupled with its relatively porous borders, the region is also the perfect stepping stone for contraband heading to European shores. While blessed with an enviable wealth of marine and mineral resources, the region is also plagued by an ever-increasing spectre of maritime piracy; accounting for around 30% of incidents in African waters from 2003 to 2011. It is for these reasons that this research centres around the issues of maritime security in the Gulf of Guinea, with a particular focus on the first two decades of the 21st century. This research looks to examine the overall picture of the present state of play in the area, before going on to provide an analysis of potential regional developments in maritime security. This research begins with the analysis of concepts/phenomena that have played a notable role in the shaping of the field of maritime security, namely Globalisation and security issues in the post-Cold War era. The ensuing chapter then focuses in on the Gulf of Guinea and the issues dominating the field of maritime security in the region. The penultimate chapter presents a SWOT analysis, undertaken as part of this research with the aim of correlating opinions from a variety of sectors/professions regarding maritime security in the Gulf of Guinea. The final chapter builds upon the results obtained from the abovementioned SWOT analysis, presenting a series of potential proposals/strategies that can contribute to the field of maritime security in the region over the coming years. This research draws to a close with the presentation of conclusions taken from this particular investigation, as well as a final overview of the earlier presented proposals applicable to the field of maritime security during the second decade of the 21st century.

Insider threats: the major challenge to security risk management

Security risk management is by definition, a subjective and complex exercise and it takes time to perform properly. Human resources are fundamental assets for any organization, and as any other asset, they have inherent vulnerabilities that need to be handled, i.e. managed and assessed. However, the nature that characterize the human behavior and the organizational environment where they develop their work turn these task extremely difficult, hard to accomplish and prone to errors. Assuming security as a cost, organizations are usually focused on the efficiency of the security mechanisms implemented that enable them to protect against external attacks, disregarding the insider risks, which are much more difficult to assess. All these demands an interdisciplinary approach in order to combine technical solutions with psychology approaches in order to understand the organizational staff and detect any changes in their behaviors and characteristics. This paper intends to discuss some methodological challenges to evaluate the insider threats and its impacts, and integrate them in a security risk framework, that was defined according to the security standard ISO/IEC_JTC1, to support the security risk management process.

Evaluation of antibacterial activity of caffeic acid encapsulated by -cyclodextrins

Context: Caffeic acid is described as antibacterial, but this bioactive molecule has some issues regarding solubility and stability to environmental stress. Thus, encapsulation devices are required. Objective: The aim of this work was to study the effect of the caffeic acid encapsulation by cyclodextrins on its antibacterial activity. Materials and methods: The interactions between the caffeic acid and three cyclodextrins (-cyclodextrin (CD), 2-hydroxypropyl--cyclodextrin (HPCD) and methyl--cyclodextrin were study. Results and discussion: The formation of an aqueous soluble inclusion complex was confirmed for CD and HPCD with a 1:1 stoichiometry. The CD/caffeic acid complex showed higher stability than HPCD/caffeic acid. Caffeic acid antibacterial activity was similar at pH 3 and pH 5 against the three bacteria (K. pneumoniae, S. epidermidis and S. aureus). Conclusions: The antibacterial activity of the inclusion complexes was described here for the first time and it was shown that the caffeic acid activity was remarkably enhanced by the cyclodextrins encapsulation.

La gestión de organismos micro-regionales en la Provincia de Córdoba: Los casos de ADESUR y EINCOR

Los municipios están experimentando una transformación en sus roles, funciones y ámbitos de actuación. Entre las nuevas cuestiones que comienzan a incorporarse a la agenda de los gobiernos locales se incluyen las referidas al bienestar de la población (políticas sociales), la puesta en valor de sus sociedades y territorios, a efectos de atraer la inversión exógena o retener y alentar la propia (promoción económica) y el mejoramiento de la calidad ambiental (...). Debido a que el ámbito de resolución de estas cuestiones trasciende en muchos casos los límites territoriales del municipio, la cooperación horizontal e interjurisdiccional constituye una alternativa para el abordaje de las mismas (...). En nuestra opinión, tanto la constitución de espacios regionales como la elaboración de programas y políticas para su desarrollo deben ser resultado del consenso de los actores de las propias regiones. En efecto, si bien los criterios de homogeneidad, funcionalidad, integralidad e historicidad (a que nos hemos referido) tienen relevancia, resultan insuficientes como elementos constitutivos de lo regional. De acuerdo a este enfoque, las regiones serían, ante todo, resultado de un proceso de construcción social de los propios agentes de desarrollo presentes en ella, siendo el rol del Estado el de apuntar los procesos endógenos. Objetivos generales: * Analizar las experiencias de cooperación intermunicipal acontecidas en la Provincia de Córdoba a partir del año 1988. * Evaluar su evolución y perspectivas en orden a la institucionalización de organismos micro-regionales de carácter permanente. * Formular un modelo de gestión de Entes Micro-regionales de Cooperación Intermunicipal. * Elaborar un programa de asistencia técnica a la Cooperación Intermunicipal e Interinstitucional, dirigido a las Municipalidades, Entes Intermunicipales y Gobierno Provincial. Objetivos específicos: * Realizar un estudio comparativo de las dos experiencias más importantes de cooperación intermunicipal que están teniendo lugar en la Provincia de Córdoba: Adesur (Asociación Interinstitucional para el Desarrollo del Sur de Córdoba) y Eincor (Ente Intercomunal para la Promoción del Norte Córdobés).

Dispersión agrícola y cambio social en las Sierras de Córdoba (ca. 1000 a C.- 1600 d C.) Agricultural spread and social change in Córdoba Hills (ca. 1000 b C- 1600 a D.)

El proceso cultural en las Sierras de Córdoba fue habitualmente concebido como marginal con respecto al Noroeste Argentino. Tras el establecimiento del esquema básico de la secuencia prehispánica, a mediados del siglo pasado, se definió una etapa agroalfarera de cronología tardía, que continuaba a una extensa etapa precerámica cuyos límites se aproximaban a la transición Pleistoceno-Holoceno. Se hacía referencia, de este modo, al advenimiento de un modo de vida agrícola y aldeano, que reemplazaba a otro basado en la caza y recolección. Dicha transformación, alternativamente atribuida a la población cazadora local o a una migración de grupos agricultores desde regiones vecinas, se habría consumado hacia 1500 AP, fijando uno de los límites de la dispersión de la agricultura andina. Es necesario destacar la extremada escasez y el carácter indirecto de las evidencias arqueológicas utilizadas para sustentar la ocurrencia de tal proceso. Asimismo, la vigencia de supuestos que han comenzado a mostrar inconsistencias con los resultados de las recientes investigaciones. Entre ellos, principalmente, el que asume que la introducción de la agricultura dio paso a una transformación radical de las sociedades prehispánicas, constituyendo un hito fundamental en su devenir histórico, el comienzo de una nueva etapa. Nuestros últimos estudios en el sector central de las Sierras de Córdoba apuntaron, entre otros objetivos, a reconocer indicadores arqueológicos directos de producción agrícola, así como de la manipulación y consumo de plantas cultivadas. Los primeros resultados nos permiten vislumbrar un escenario complejo que desafía los modelos vigentes. El consumo de maíz, por ejemplo, parece haber antecedido por muchos siglos a la adopción de prácticas agrícolas. El acceso a este cultígeno, sumado a otros elementos, indicaría cambios entre los cazadores-recolectores serranos, promovidos por su integración en redes macrorregionales que los vincularon con sociedades agricultoras de la vertiente oriental andina y quizás del Chaco Santiagueño, por lo menos desde 2500 AP. En definitiva, la agricultura no parece haber sido adoptada rápidamente ni provocado transformaciones profundas e inmediatas en la organización de los grupos prehispánicos. Se ha observado, por el contrario, la incorporación gradual de distintas innovaciones que incluso permiten relacionar la manipulación y más tarde el cultivo de plantas domesticadas, con procesos de intensificación productiva de mayor escala temporal. Uno de nuestros objetivos en este proyecto consiste, básicamente, en profundizar las investigaciones en curso a fin de ampliar el cuerpo de datos con el cual analizar y discutir el problema de la dispersión agrícola en la región. Ello implica el tratamiento de diferentes líneas de evidencia, en particular: 1) la distribución regional de sitios arqueológicos y las modalidades de ocupación de las tierras cultivables; 2) la búsqueda de superficies de cultivo en sitios estratificados; y 3) estudios arqueobotánicos, polínicos y de isótopos estables. Se entiende que no le corresponde a la arqueología asumir apriorísticamente el significado histórico de la introducción de la agricultura, sino establecerlo en cada caso puntual a través de la investigación concreta. Nuestro segundo objetivo consiste, por lo tanto, en delinear los cambios (económicos, tecnológicos, políticos, sociales) que acompañaron al proceso de dispersión agrícola. Ello implica el tratamiento de diferentes problemas, entre otros: 1) las prácticas de apropiación de los recursos silvestres; 2) la continuidad y cambio tecnológico; 3) la movilidad y la articulación microambiental; y 4) los aspectos políticos y sociales ligados a prácticas como la molienda grupal y la producción del arte rupestre. The radical chage of societies from hunter-gatherers to farmers in 1500 BP was considered a milestone whitin the cultural process of pre-hispanic societies in Cordoba Hill. But there is a shortage of archaeological remains to support this change and there are weak hypotheses of absolute transformations. During the last years, our studies carried out on the central area of Cordoba Hill have tried to recognize direct archaeological signs of agriculture production as well as the handling and consumption of crops. The first results show a complex set that challenges the current theoretical models. For example, the corn was probably eatten prior to its adoption for farm practices. Our first main consists in increasing a corpus of data about the spread of agriculture in Cordoba region that we have been researching for the last years. These researches involve different lines of evidence: 1-regional location of archaeological sites and kinds of occupation on cultivable lands; 2-the search for plots at archaeological sites; 3-archaeobotanical, pollen and stable isotopes studies. Our second main consists in outlining changes within the spread of agriculture. It implies to considering different problems: 1-the practices to gatherer wild resources; 2-the continuity and changes of technologies; 3-the mobility and the articulation on the micro-environment; 4-political and social aspects in connection with activities such as groupal grinding and rock art productions.

Desarrollo de sistemas nano/micro-particulados con aplicación en la fotodegradación selectiva de contaminantes orgánicos en solución. Development of nano / micro-particles systems with application to selective photodegradation of organic pollutants in solution.

IDENTIFICACIÓN DEL PROBLEMA DE ESTUDIO. Las sustancias orgánicas solubles en agua no biodegradables tales como ciertos herbicidas, colorantes industriales y metabolitos de fármacos de uso masivo son una de las principales fuentes de contaminación en aguas subterráneas de zonas agrícolas y en efluentes industriales y domésticos. Las reacciones fotocatalizadas por irradiación UV-visible y sensitizadores orgánicos e inorgánicos son uno de los métodos más económicos y convenientes para la descomposición de contaminantes en subproductos inocuos y/o biodegradables. En muchas aplicaciones es deseable un alto grado de especificidad, efectividad y velocidad de degradación de un dado agente contaminante que se encuentra presente en una mezcla compleja de sustancias orgánicas en solución. En particular son altamente deseables sistemas nano/micro -particulados que formen suspensiones acuosas estables debido a que estas permiten una fácil aplicación y una eficaz acción descontaminante en grandes volúmenes de fluidos. HIPÓTESIS Y PLANTEO DE LOS OBJETIVOS. El objetivo general de este proyecto es desarrollar sistemas nano/micro particulados formados por polímeros de impresión molecular (PIMs) y foto-sensibilizadores (FS). Un PIMs es un polímero especialmente sintetizado para que sea capaz de reconocer específicamente un analito (molécula plantilla) determinado. La actividad de unión específica de los PIMs en conjunto con la capacidad fotocatalizadora de los sensibilizadores pueden ser usadas para lograr la fotodescomposición específica de moléculas “plantilla” (en este caso un dado contaminante) en soluciones conteniendo mezclas complejas de sustancias orgánicas. MATERIALES Y MÉTODOS A UTILIZAR. Se utilizaran técnicas de polimerización en mini-emulsión para sintetizar los sistemas nano/micro PIM-FS para buscar la degradación de ciertos compuestos de interés. Para caracterizar eficiencias, mecanismos y especificidad de foto-degradación en dichos sistemas se utilizan diversas técnicas espectroscópicas (estacionarias y resueltas en el tiempo) y de cromatografía (HPLC y GC). Así mismo, para medir directamente distribuciones de afinidades de unión y eficiencia de foto-degradación se utilizaran técnicas de fluorescencia de molécula/partícula individual. Estas determinaciones permitirán obtener resultados importantes al momento de analizar los factores que afectan la eficiencia de foto-degradación (nano/micro escala), tales como cantidad y ubicación de foto- sensibilizadores en las matrices poliméricas y eficiencia de unión de la plantilla y los productos de degradación al PIM. RESULTADOS ESPERADOS. Los estudios propuestos apuntan a un mejor entendimiento de procesos foto-iniciados en entornos nano/micro-particulados para aplicar dichos conocimientos al diseño de sistemas optimizados para la foto-destrucción selectiva de contaminantes acuosos de relevancia social; tales como herbicidas, residuos industriales, metabolitos de fármacos de uso masivo, etc. IMPORTANCIA DEL PROYECTO. Los sistemas nano/micro-particulados PIM-FS que se propone desarrollar en este proyecto se presentan como candidatos ideales para tratamientos específicos de efluentes industriales y domésticos en los cuales se desea lograr la degradación selectiva de compuestos orgánicos. Los conocimientos adquiridos serán indispensables para construir una plataforma versátil de sistemas foto-catalíticos específicos para la degradación de diversos contaminantes orgánicos de interés social. En lo referente a la formación de recursos humanos, el proyecto propuesto contribuirá en forma directa a la formación de 3 estudiantes de postgrado y 2 estudiantes de grado. En las capacidades institucionales se contribuirá al acondicionamiento del Laboratorio para Microscopía Óptica Avanzada (LMOA) en el Dpto. de Química de la UNRC y al montaje de un sistema de microscopio de fluorescencia que permitirá la aplicación de técnicas avanzadas de espectroscopia de fluorescencia de molecula individual. Water-soluble organic molecules such as certain non-biodegradable herbicides, industrial dyes and metabolites of widespread use drugs are a major source of pollution in groundwater from agricultural areas and in industrial and domestic effluents. Photo-catalytic reactions by UV-visible irradiation and organic sensitizers are one of the most economical and convenient methods for the decomposition of pollutants into harmless byproducts. In many applications it is highly desirable a high degree of specificity, effectiveness and speed of degradation of specific pollutants present in a complex mixture. In particular nano/micro-particles systems that form stable aqueous suspensions are highly desirable because they allow for easy application and effective decontamination of large volumes of fluids. Herein we propose the development of nano/micro particles composed by molecularly imprinted polymers (MIP) and photo-sensitizers (PS). The specific binding of MIP and the photo-catalytic ability of the sensitizers are used to achieve the photo-decomposition of specific "template" molecules in complex mixtures. Mini-emulsion polymerization techniques will be used to synthesize nano/micro MIP-FS systems. Spectroscopy (steady-state and time resolved) and chromatography (GC and HPLC) will be used to characterize efficiency, mechanisms and specificity of photo-degradation in these systems. In addition single molecule/particle fluorescence spectroscopy techniques will be used to directly measure distributions of binding affinities and photo-degradation efficiency in individual particles. The proposed studies point to a more detailed understanding of the factors affecting the photo-degradation efficiency in nano/micro-particles and to apply that knowledge in the design of optimized systems for photo-selective destruction of socially relevant aqueous pollutants.

Procesos oxidativos en matrices alimentarias complejas. Oxidative processes in complex food matrices.

Las reacciones bioquímicas que ocurren como consecuencia del tratamiento y almacenamiento de los alimentos, mejoran la seguridad alimentaria, las propiedades sensoriales y la vida útil. Sin embargo, el tratamiento térmico, la exposición a la luz y el oxígeno pueden causar daño oxidativo a los lípidos y proteínas. Los procesos oxidativos de matrices complejas tienen características distintivas que no se manifiestan cuando los componentes son sometidos a oxidación individualmente. La hipótesis de trabajo es que la oxidación de proteínas en matrices alimentarias complejas altera la estructura y las propiedades funcionales de las proteínas y, que las modificaciones que se producen varían según las condiciones de procesamiento y de la composición química del alimento. Nuestros estudios intentan demostrar que el estado oxidativo de las proteínas de un alimento es un parámetro importante para la evaluación de las propiedades funcionales, sensoriales y nutricionales de un producto lácteo. El objetivo general del proyecto es el estudio de los procesos de oxidación de matrices alimentarias complejas (la leche, miel) y su relación con distintos procesos y materiales utilizados en la industria. Es decir, nos proponemos estudiar las consecuencias funcionales y biológicas (calidad nutricional, coagulación) de la oxidación proteica en modelos experimentales “in vitro” y en productos comerciales. 1. Estudiar los fenómenos de peroxidación proteica en leche entera y descremada sometida a los distintos procesos tecnológicos de la producción de leche y queso a escala laboratorio. Se realizarán las mismas experiencias con albúmina sérica y con proteínas aisladas de suero de leche para comparar diferencias entre una matriz compleja y una simple. 2. Determinar la relación entre oxidación y composición proteica de la leche, y los cambios en las fracciones proteicas aisladas (caseínas y beta-lactoglobulina). 3. Analizar el impacto de los procesos tecnológicos a nivel de producción primaria (composición proteica y estado de oxidación) en los indicadores de inflamación (contenido de células somáticas y proteína C Reactiva) y de estado redox (capacidad antioxidante de los productos lácteos y nivel de carbonilos de proteinas). 4. Comparar las características de composición química y el estado de oxidación de leche provenientes de las tres regiones (Buenos Aires, Santa Fe y Córdoba) que conforman la cuenca láctea Argentina. Este objetivo se realizará conjuntamente con los integrantes de nuestro grupo de investigación que trabajan en el Laboratorio de Control de Calidad de la Escuela Superior de Lechería. 5. Determinar los metabolitos secundarios de mieles uniflorales propuestos como responsables de la capacidad antioxidante de estas (polifenoles) y como indicadores de su origen botánico. 6. Valorar la capacidad antioxidante total de mieles uniflorales. 7. Validar los métodos analíticos y semicuantitativos utilizados y a utilizar en el presente proyecto teniendo en cuenta lo efectos de matrices típico de los fluidos biológicos y las mezclas. El estudio de las modificaciones oxidativas de matrices complejas es un tema que es importante tanto desde el punto de vista del conocimiento básico como del aplicado. Nosotros creemos que el presente proyecto aportará conocimiento sobre las características de las vías oxidativas de proteínas en matrices complejas y que podrá ser utilizado para diseñar estrategias productivas tendientes a disminuir el deterioro de la calidad de la leche debido a la exposición a energía radiante. Parte de la experiencia ganada por el grupo ha sido ya volcada a subsanar dificultades y problemas de oxidación y deterioro de la calidad de alimentos. Además, se contribuirá a discernir la paradoja que existe en el área sobre las propiedades oxidantes/antioxidantes de los polifenoles y la relación entre estas y el estado oxidativo de un alimento. The biochemical reactions that occur as a result of food treatment and storage, improve food security, sensory properties and shelf life. Heat treatment, exposure to light and oxygen can cause oxidative damage to lipids and proteins. Oxidative processes in complex matrices display distinctive features that do not appear when the components are individually subjected to oxidation. The hypothesis is that protein oxidation in complex food matrices alters the structure and functional properties of proteins and that the modifications vary according to process conditions and food composition. The main goal is to study oxidation of complex food matrices (milk, honey) with different processes and materials used in the industry. The specific aims are: 1. To study protein oxidation in whole milk and skim subject to various technological processes. The same experiences will be done with serum albumin and isolated whey proteins to compare complex and simple matrices. 2. To determine the relationship between oxidation and milk protein composition, and changes in casein and beta-lactoglobulin. 3. Analyze the impact of technological processes at the level of primary production on markers of inflammation and redox (antioxidant capacity and protein carbonyls). 4. Compare characteristics of chemical composition and oxidation state of milk. 5. Determine secondary metabolites of honey responsible for the antioxidant capacity of these. 6. To evaluate the total antioxidant capacity unifloral honey. This project will provide knowledge about characteristics of oxidative pathways of proteins in complex matrices that can be used to design production strategies aimed at reduce the deterioration of milk quality. Also, it would help to discern the paradox that exists on the oxidants/antioxidants properties of polyphenols and the relationship between these and the oxidative status of a food.

The EU as a security provider in its neighbourhood: the case of non-proliferation of WMD in the Mediterranean area

As a consequence of the terrorist attacks of 9/11 and the US-led war against Iraq, WMD and their proliferation have become a central element of the EU security agenda. In December 2003, the European Council adopted even a EU Strategy against Proliferation of WMD. The approach adopted in this Strategy can be largely described as a ‘cooperative security provider’ approach and is based on effective multilateralism, the promotion of a stable international and regional environment and the cooperation with key partners. The principal objective of this paper is to examine in how far the EU has actually implemented the ‘cooperative security provider’ approach in the area which the Non-proliferation Strategy identifies as one of its priorities – the Mediterranean. Focusing on the concept of security interdependence, the paper analyses first the various WMD dangers with which the EU is confronted in the Mediterranean area. Afterwards, it examines how the EU has responded to these hazards in the framework of the Barcelona process and, in particular, the new European Neighbourhood Policy. It is argued that despite its relatively powerful rhetoric, the EU has largely failed, for a wide range of reasons, to apply effectively its non-proliferation approach in the Mediterranean area and, thus, to become a successful security provider.
