rnNitric oxide (NO) is important for several chemical processes in the atmosphere. Together with nitrogen dioxide (NO2 ) it is better known as nitrogen oxide (NOx ). NOx is crucial for the production and destruction of ozone. In several reactions it catalyzes the oxidation of methane and volatile organic compounds (VOCs) and in this context it is involved in the cycling of the hydroxyl radical (OH). OH is a reactive radical, capable of oxidizing most organic species. Therefore, OH is also called the “detergent” of the atmosphere. Nitric oxide originates from several sources: fossil fuel combustion, biomass burning, lightning and soils. Fossil fuel combustion is the largest source. The others are, depending on the reviewed literature, generally comparable to each other. The individual sources show a different temporal and spatial pattern in their magnitude of emission. Fossil fuel combustion is important in densely populated places, where NO from other sources is less important. In contrast NO emissions from soils (hereafter SNOx) or biomass burning are the dominant source of NOx in remote regions.rnBy applying an atmospheric chemistry global climate model (AC-GCM) I demonstrate that SNOx is responsible for a significant part of NOx in the atmosphere. Furthermore, it increases the O3 and OH mixing ratio substantially, leading to a ∼10% increase in the oxidizing efficiency of the atmosphere. Interestingly, through reduced O3 and OH mixing ratios in simulations without SNOx, the lifetime of NOx increases in regions with other dominating sources of NOx

Humankind today is challenged by numerous threats brought about by the speed and scope of global change dynamics. A concerted and informed approach to solutions is needed to face the severity and magnitude of current development problems. Generating shared knowledge is a key to addressing global challenges. This requires developing the ability to cross multiple borders wherever radically different understandings of issues such as health and environmental sanitation, governance and conflict, livelihood options and globalisation, and natural resources and development exist. Global Change and Sustainable Development presents 36 peer-reviewed articles written by interdisciplinary teams of authors who reflected on results of development-oriented research conducted from 2001 to 2008. Scientific activities were – and continue to be – carried out in partnerships involving people and institutions in the global North, South and East, guided by principles of sustainability. The articles seek to inform solutions for mitigating, or adapting to, the negative impacts of global dynamics in the social, political, ecological, institutional and economic spheres.

The immune system exhibits an enormous complexity. High throughput methods such as the "-omic'' technologies generate vast amounts of data that facilitate dissection of immunological processes at ever finer resolution. Using high-resolution data-driven systems analysis, causal relationships between complex molecular processes and particular immunological phenotypes can be constructed. However, processes in tissues, organs, and the organism itself (so-called higher level processes) also control and regulate the molecular (lower level) processes. Reverse systems engineering approaches, which focus on the examination of the structure, dynamics and control of the immune system, can help to understand the construction principles of the immune system. Such integrative mechanistic models can properly describe, explain, and predict the behavior of the immune system in health and disease by combining both higher and lower level processes. Moving from molecular and cellular levels to a multiscale systems understanding requires the development of methodologies that integrate data from different biological levels into multiscale mechanistic models. In particular, 3D imaging techniques and 4D modeling of the spatiotemporal dynamics of immune processes within lymphoid tissues are central for such integrative approaches. Both dynamic and global organ imaging technologies will be instrumental in facilitating comprehensive multiscale systems immunology analyses as discussed in this review.

About one-sixth of the world’s land area, that is, about one-third of the land used for agriculture, has been affected by soil degradation in the historic past. While most of this damage was caused by water and wind erosion, other forms of soil degradation are induced by biological, chemical, and physical processes. Since the 1950s, pressure on agricultural land has increased considerably owing to population growth and agricultural modernization. Small-scale farming is the largest occupation in the world, involving over 2.5 billion people, over 70% of whom live below the poverty line. Soil erosion, along with other environmental threats, particularly affects these farmers by diminishing yields that are primarily used for subsistence. Soil and water conservation measures have been developed and applied on many farms. Local and science-based innovations are available for most agroecological conditions and land management and farming types. Principles and measures developed for small-scale as well as modern agricultural systems have begun to show positive impacts in most regions of the world, particularly in wealthier states and modern systems. Much more emphasis still needs to be given to small-scale farming, which requires external support for investment in sustainable land management technologies as an indispensable and integral component of farm activities.

Earth observations (EO) represent a growing and valuable resource for many scientific, research and practical applications carried out by users around the world. Access to EO data for some applications or activities, like climate change research or emergency response activities, becomes indispensable for their success. However, often EO data or products made of them are (or are claimed to be) subject to intellectual property law protection and are licensed under specific conditions regarding access and use. Restrictive conditions on data use can be prohibitive for further work with the data. Global Earth Observation System of Systems (GEOSS) is an initiative led by the Group on Earth Observations (GEO) with the aim to provide coordinated, comprehensive, and sustained EO and information for making informed decisions in various areas beneficial to societies, their functioning and development. It seeks to share data with users world-wide with the fewest possible restrictions on their use by implementing GEOSS Data Sharing Principles adopted by GEO. The Principles proclaim full and open exchange of data shared within GEOSS, while recognising relevant international instruments and national policies and legislation through which restrictions on the use of data may be imposed.The paper focuses on the issue of the legal interoperability of data that are shared with varying restrictions on use with the aim to explore the options of making data interoperable. The main question it addresses is whether the public domain or its equivalents represent the best mechanism to ensure legal interoperability of data. To this end, the paper analyses legal protection regimes and their norms applicable to EO data. Based on the findings, it highlights the existing public law statutory, regulatory, and policy approaches, as well as private law instruments, such as waivers, licenses and contracts, that may be used to place the datasets in the public domain, or otherwise make them publicly available for use and re-use without restrictions. It uses GEOSS and the particular characteristics of it as a system to identify the ways to reconcile the vast possibilities it provides through sharing of data from various sources and jurisdictions on the one hand, and the restrictions on the use of the shared resources on the other. On a more general level the paper seeks to draw attention to the obstacles and potential regulatory solutions for sharing factual or research data for the purposes that go beyond research and education.

Los retos y oportunidades a los que se enfrentan las organizaciones y administraciones de las primeras décadas del siglo XXI se caracterizan por una serie de fuerzas perturbadoras como la globalización, el avance de las tecnologías emergentes y el desequilibrio económico, que están actuando como impulsores de la transformación del mercado. La acción conjunta de estos factores está obligando a todas las empresas industriales a tener que trabajar con mayores y más exigentes niveles de productividad planteándose continuamente como mejorar y lograr satisfacer los requerimientos de los clientes. De esta situación surge la necesidad de volver a plantearse de nuevo ¿quién es el cliente?, ¿qué valora el cliente? y ¿cómo se pueden generan beneficios sostenibles? La aplicación de esta reflexión a la industria naval militar marca los objetivos a los que esta tesis doctoral busca dar respuesta. El primer objetivo, de carácter general, consiste en la definición de un modelo de negocio sostenible para la industria naval militar del 2025 que se adapte a los requisitos del cliente y al nuevo escenario político, económico, social, tecnológico y ambiental que rodea esta industria. El segundo objetivo, consecuencia del modelo general, trata de desarrollar una metodología para ejecutar programas de apoyo al ciclo de vida del “buque militar”. La investigación se estructura en cuatro partes: en la primera se justifica, por un lado, la necesidad del cambio de modelo y por otro se identifican los factores estructurantes para la definición del modelo. La segunda parte revisa la literatura existente sobre uno de los aspectos básicos para el nuevo modelo, el concepto Producto-Servicio. La tercera parte se centra totalmente en la industria naval militar estudiando los aspectos concretos del sector y, en base al trabajo de campo realizado, se identifican los puntos que más valoran las Marinas de Guerra y como estas gestionan al buque militar durante todo su ciclo de vida. Por último se presentan los principios del modelo propuesto y se desarrollan los pilares básicos para la ejecución de proyectos de Apoyo al Ciclo de Vida (ACV). Como resultado de la investigación, el modelo propuesto para la industria naval militar se fundamenta en once principios: 1. El buque militar (producto de alto valor añadido) debe ser diseñado y construido en un astillero del país que desarrolla el programa de defensa. 2. El diseño tiene que estar orientado al valor para el cliente, es decir, se tiene que diseñar el buque militar para que cumpla su misión, eficaz y eficientemente, durante toda su vida operativa, asegurando la seguridad del buque y de las personas y protegiendo el medio ambiente de acuerdo con las regulaciones vigentes. 3. La empresa debe suministrar soluciones integrales de apoyo al ciclo de vida al producto. 4. Desarrollar y mantener las capacidades de integración de sistemas complejos para todo el ciclo de vida del buque militar. 5. Incorporar las tecnologías digitales al producto, a los procesos, a las personas y al propio modelo de negocio. 6. Desarrollar planes de actuación con el cliente domestico a largo plazo. Estos planes tienen que estar basados en tres premisas: (i) deben incluir el ciclo de vida completo, desde la fase de investigación y desarrollo hasta la retirada del buque del servicio; (ii) la demanda debe ser sofisticada, es decir las exigencias del cliente, tanto desde la óptica de producto como de eficiencia, “tiran” del contratista y (iii) permitir el mantenimiento del nivel tecnológico y de las capacidades industriales de la compañía a futuro y posicionarla para que pueda competir en el mercado de exportación. 7. Impulsar el sector militar de exportación mediante una mayor actividad comercial a nivel internacional. 8. Fomentar la multilocalización ya que representa una oportunidad de crecimiento y favorece la exportación posibilitando el suministro de soluciones integrales en el país destino. 9. Reforzar la diplomacia institucional como palanca para la exportación. 10. Potenciar el liderazgo tecnológico tanto en producto como en procesos con políticas activas de I + D+ i. 11. Reforzar la capacidad de financiación con soluciones innovadoras. El segundo objetivo de esta tesis se centra en el desarrollo de soluciones integrales de Apoyo al Ciclo de Vida (ACV). La metodología planteada trata de minimizar la brecha entre capacidades y necesidades a lo largo de la vida operativa del barco. Es decir, el objetivo principal de los programas de ACV es que la unidad conserve durante toda su vida operativa, en términos relativos a las tecnologías existentes, las capacidades equivalentes a las que tendrá cuando entre en servicio. Los ejes de actuación para conseguir que un programa de Apoyo al Ciclo de Vida cumpla su objetivo son: el diseño orientado al valor, la ingeniería de Apoyo al Ciclo de Vida, los proyectos de refresco de tecnología, el mantenimiento Inteligente y los contratos basados en prestaciones. ABSTRACT On the first decades of the 21st century, organizations and administrations face challenges and come across opportunities threatened by a number of disruptive forces such as globalization, the ever-changing emerging technologies and the economic imbalances acting as drivers of the market transformation. This combination of factors is forcing all industrial companies to have more and higher demanding productivity levels, while bearing always in mind how to improve and meet the customer’s requirements. In this situation, we need to question ourselves again: Who is the customer? What does the customer value? And how can we deliver sustainable economic benefits? Considering this matter in a military naval industry framework sets the goals that this thesis intends to achieve. The first general goal is the definition of a new sustainable business model for the 2025 naval industry, adapted to the customer requirements and the new political, economic, social, technological and environmental scenario. And the second goal that arises as a consequence of the general model develops a methodology to implement “warship” through life support programs. The research is divided in four parts: the first one justifies, on the one hand, the need to change the existing model and, on the other, identifies the model structural factors. On the second part, current literature regarding one of the key issues on the new model (the Product-Service concept) is reviewed. Based on field research, the third part focuses entirely on military shipbuilding, analyzing specific key aspects of this field and identifying which of them are valued the most by Navies and how they manage through life cycles of warships. Finally, the foundation of the proposed model is presented and also the basic grounds for implementing a Through Life Support (TLS) program are developed. As a result of this research, the proposed model for the naval industry is based on eleven (11) key principles: 1. The warship (a high added value product) must be designed and built in a shipyard at the country developing the defense program. 2. Design must be customer value oriented, i.e.warship must be designed to effectively fulfill its mission throughout its operational life, ensuring safety at the ship and for the people and protecting the environment in accordance with current regulations. 3. The industry has to provide integrated Through Life Support solutions. 4. Develop and maintain integrated complex systems capabilities for the entire warship life cycle. 5. Introduce the product, processes, people and business model itself to digital technologies. 6. Develop long-term action plans with the domestic customer. These plans must be based on three premises: (i) the complete life cycle must be included, starting from the research and development stage throughout the ship’s disposal; (ii) customer demand has to be sophisticated, i.e. customer requirements, both from the efficiency and product perspective, "attract" the contractor and (iii) technological level and manufacturing capabilities of the company in the future must be maintained and a competitive position on the export market has to be achieved. 7. Promote the military exporting sector through increased international business. 8. Develop contractor multi-location as it entails an opportunity for growth and promote export opportunities providing integrated solutions in the customer's country. 9. Strengthen institutional diplomacy as a lever for export. 10. Promote technological leadership in both product and processes with active R & D & I policies (Research & Development & Innovation) 11. Strengthen financing capacity through innovative solutions. The second goal of this thesis is focused on developing integrated Through Life Support (TLS) solutions. The proposed methodology tries to minimize the gap between needs and capabilities through the ship operational life. It means, the main TLS program objective is to maintain the ship’s performance and capabilities during operational life, in relative terms to current technologies, equivalent to those the ship had when it entered service. The main actions to fulfill the TLS program objectives are: value-oriented design, TLS engineering, technology updating projects, intelligent maintenance and performance based contracts.

Las ONG de Desarrollo (ONGD) contribuyen a informar sobre lo las distintas realidades sociales del siglo XXI. Sin embargo, en ocasiones, la representación de las personas culturalmente diferentes está llena de prejuicios y de estereotipos, hecho que todavía queda más marcado cuando se trata de mujeres. Así, nuestro objetivo con esta comunicación es observar la representación de mujeres de otras culturas en una muestra de las revistas publicadas por la ONGD Oxfam Intermón desde mayo de 2013 hasta mayo de 2014. El corpus empleado para el análisis serán las portadas de las revistas. Se seleccionaron algunos de estos textos donde aparecían representadas mujeres para llevar a cabo una experiencia didáctica. Se explicó el modo de analizar textos con imagen y se pidió al alumnado que los analizara con el fin de desarrollar su capacidad crítica y su conciencia social. Los marcos teóricos de este estudio serán los principios del Análisis Crítico del Discurso (van Dijk 2005, 2009) y la Gramática Visual (Kress y van Leeuwen, 2006) para explorar las principales estrategias lingüísticas y visuales empleadas para presentar a mujeres. Los resultados del estudio ponen de manifiesto que la práctica docente llevada a cabo hace que el alumnado tome conciencia de que el modo en que las mujeres aparecen representadas en las revistas de Oxfam Intermón contribuye a modificar la imagen negativa que normalmente tenemos sobre éstas. La representación positiva que se observa contribuye a cambiar la percepción del alumnado. Como conclusiones podemos señalar la importancia del emplear textos sobre temas sociales para que el alumnado adquiera competencias emocionales y mejore su capacidad crítica. Además, estos textos señalan que las mujeres van avanzando hacia el empoderamiento en todos los lugares del planeta de modo que se cumplen progresivamente los objetivos del milenio.

The Asian financial crisis (1997) and the European crisis (2009) have both contributed to the development and deepening of regional safety net arrangements. This paper analyses the relationships between global and regional financial safety nets, and uncovers the potential tensions and operational challenges associated with the involvement of several institutional players with potentially different interests, analytical biases and governance. The G20 has acknowledged the importance of these new players for the international monetary system, but the principles for cooperation between the IMF and regional financing arrangements are far too broad and ad hoc to contribute to a coherent and effective architecture. This paper tries to establish some lessons learned from the Asian financial crisis in 1997 and the current European crisis in order to enhance the effectiveness, efficiency, equity and governance of these arrangements. In particular, it proposes changes to the IMF articles of agreement to allow for lending or guarantees to regional arrangements directly and it establishes some key desirable features and practices of regional mechanisms that should be adopted everywhere to ensure some global consistency, particularly in the field of macroeconomic surveillance, programme design and conditionality.

This paper theorizes about the convergence of international organizations in global health governance, a field of international cooperation that is commonly portrayed as particularly hit by institutional fragmentation. Unlike existing theories on interorganizationalism that have mainly looked to intra- and extraorganizational factors in order to explain why international organizations cooperate with each other in the first place, the paper is interested in the link between causes and systemic effects of interorganizational convergence. The paper begins by defining interorganizational convergence. It then proceeds to discuss why conventional theories on interorganizational- ism fail to explain the aggregate effects of convergence between IOs in global (health) governance which tend to worsen rather than cushion fragmentation — so-called "hypercollective action" (Severino & Ray 2010). In order to remedy this explanatory blind-spot the paper formulates an alternative sociological institutionalist theory on interorganizational convergence that makes two core theoretical propositions: first that emerging norms of metagovernance are a powerful driver behind interorganizational convergence in global health governance, and secondly that IOs are engaged in a fierce meaning-struggle over these norms which results in hypercollective action. In its empirical part, the paper’s core theoretical propositions are corroborated by analyzing discourses and practices of interorganizational convergence in global health. The empirical analysis allows drawing two far-reaching conclusions. On the one hand, interorganizational harmonization has emerged as a largely undisputed norm in global health which has been translated into ever more institutionalized forms of interorganizational cooperation. On the other, discourses and practices of interorganizational harmonization exhibit conflicts over the ordering principles according to which the policies and actions of international organizations with overlapping mandates and missions should be harmonized. In combination, these two empirical findings explain why interorganizational convergence has so far failed to strengthen the global health architecture.

The meeting was convened by 1net, a coalition of stakeholder groups involved in Internet governance discussions, in partnership with the Brazilian Internet Steering Committee (CGI.br), in response to revelations of mass surveillance of communications by the United States. It sought to develop a set of universally acceptable Internet governance principles as well as a way forward for the evolution of the Internet governance system, which together could serve as a framework for the governance and use of the Internet. It convened 930 participants from 110 different countries, representing civil society, the private sector, academia, the technical community, governments and intergovernmental organizations, as well as over 1000 remote participants from 23 countries around the globe. It also employed a content contribution platform that sought to crowd source inputs from stakeholders for the production of the outcome document. The meeting served as a demonstration of the multistakeholder process in action: in the production of the outcome document, stakeholders with a diverse range of backgrounds and interests collectively negotiated the inclusion or exclusion of highly sensitive and complex issues. While the process of achieving rough consensus involved sometimes messy debates and there were procedural imperfections, the case is informative for its structured production of bottom-up multistakeholder outcomes.groups involved in Internet governance discussions, in partnership with the Brazilian Internet Steering Committee (CGI.br), in response to revelations of mass surveillance of communications by the United States.
