Dengue virus types 1 and 2 have been isolated in Brazil by the Department of Virology, Instituto Oswaldo Cruz, in 1986 and 1990 respectively, after many decades of absence. A successful continental Aedes aegypti control program in the Americas, has been able to eradicate the vector in most countries in the 60's, but the program could not be sustained along the years. Dengue viruses were reintroduced in the American region and the infection became endemic in Brazil, like in most Central and SouthAmerican countries and in the Caribbean region, due to the weaning of the vector control programs in these countries. High demographic densities and poor housing conditions in large urban communities, made the ideal conditions for vector spreading. All four dengue types are circulating in the continent and there is a high risk of the introduction in the country of the other two dengue types in Brazil, with the development of large epidemics. After the Cuban episode in 1981, when by the first time a large epidemic of dengue hemorrhagic fever and dengue shock syndrome have been described in the Americas, both clinical presentations are observed, specially in the countries like Brazil, with circulation of more than one dengue virus type. A tetravalent potent vaccine seems to be the only possible way to control the disease in the future, besides rapid clinical and laboratory diagnosis, in order to offer supportive treatment to the more severe clinical infections.

The research performed a sustainability assessment of supply chains of the anchoveta (Engraulis ringens) in Peru. The corresponding fisheries lands 6.5 million t per year, of which <2% is rendered into products for direct human consumption (DHC) and 98% reduced into feed ingredients (fishmeal and fish oil, FMFO), for export. Several industries compete for the anchoveta resources, generating local and global impacts. The need for understanding these dynamics, towards sustainability-improving management and policy recommendations, determined the development of a sustainability assessment framework: 1) characterisation and modelling of the systems under study (with Life Cycle Assessment and other tools) including local aquaculture, 2) calculation of sustainability indicators (i.e. energy efficiency, nutritional value, socio-economic performances), and 3) sustainability comparison of supply chains; definition and comparison of alternative exploitation scenarios. Future exploitation scenarios were defined by combining an ecosystem and a material flow models: continuation of the status quo (Scenario 1), shift towards increased proportion of DHC production (Scenario 2), and radical reduction of the anchoveta harvest in order for other fish stocks to recover and be exploited for DHC (Scenario 3). Scenario 2 was identified as the most sustainable. Management and policy recommendations include improving of: controls for compliance with management measures, sanitary conditions for DHC, landing infrastructure for small- and medium-scale (SMS) fisheries; the development of a national refrigerated distribution chain; and the assignation of flexible tolerances for discards from different DHC processes.

Here we examine the role of Reelin, an extracellular protein involved in neuronal migration, in the formation of hippocampal connections. Both at prenatal and postnatal stages, the general laminar and topographic distribution of entorhinal projections is preserved in the hippocampus of reeler mutant mice, in the absence of Reelin. However, developing and adult entorhinal afferents show severe alterations, including increased numbers of misrouted fibers and the formation of abnormal patches of termination from the medial and lateral entorhinal cortices. At perinatal stages, single entorhinal axons in reeler mice are grouped into thick bundles, and they have decreased axonal branching and decreased extension of axon collaterals. We also show that the number of entorhino-hippocampal synapses is lower in reeler mice than in control animals during development. Studies performed in mixed entorhino-hippocampal co-cultures combining slices from reeler and wild-type mice indicate that these abnormalities are caused by the lack of Reelin in the target hippocampus. These findings imply that Reelin fulfills a modulatory role during the formation of layer-specific and topographic connections in the hippocampus. They also suggest that Reelin promotes maturation of single fibers and synaptogenesis by entorhinal afferents.

As this is a dissertation, an academic thesis, it is important to define the objectives of my research, even if ex post facto, explicitly: - To define, develop and study the concept of business and leadership ethics. - To empirically study the phenomena associated with business and leadership from an ethical perspective. - To create a new framework for the development of responsible business. - To create an “acid test” for my body of works, i.e. a test and an evaluation on how well my research and ideas hold up under academic philosophical reflection. The utilitarian reasoning had the most support when the actors justified their actions regarding economic benefit. (=instrumental good). Duty and benefit were often mixed up in people’s speech. Their meaning contents were blurred and the argumentation lines created by the actors were broken. This can be interpreted in a way that supports Frankena’s mixed deontological philosophy as a frame of reference. Deontologica reasoning was used e.g. in describing the personnel management processes of a company. Virtue ethics is a favourable starting point for studying management and leadership ethics. All the actors studied could name virtues for their operations, towards which to aspire to. They also named professional practices already in use that they considered to be virtuous. Finally, I wish to state that normative ethics is an important branch of philosophical ethics, if also very important in applied ethics especially. From the normative standpoint, the results of this dissertation want to lead nations, communities and individuals towards the virtues of democratic leadership and sustainable economic development.

Collaboration is essential for successful new product development. In the preparation for ramp-up production collaboration between R&D and supply chain functions is crucial. This thesis examines the meaning of collaboration and the effects of collaboration between R&D and supply chain. The aim of this thesis is to analyse and advice on how to improve the collaboration between the research and development department and supply chain within the preparation for rampup process. This thesis begins by introducing the reader to the product development methodologies and collaboration literature. The following part of the thesis describes the current situation and the results of the qualitative research. The last part of the thesis will explain the improvement suggestions. The main improvement suggestions are clarification of the processes and responsibilities and the introduction of a kick-off meeting.

Au cours des dernières décennies, l’important mouvement de déconcentration territoriale évoluant au sein de nombreuses métropoles à travers le monde a indéniablement su bouleverser leurs dynamiques territoriales, notamment en termes d’organisation spatiale des fonctions urbaines et de mobilité. Ce phénomène n’a pas manqué de susciter l’intérêt de nombreux auteurs, toutefois, face à la variété des facteurs d’influence et aux nombreuses spécificités locales, ces études se sont régulièrement révélées divergentes, voire contradictoires. Ainsi, de nombreuses incertitudes demeurent. La déconcentration des activités serait-elle en mesure de favoriser une meilleure adéquation des lieux de résidence et de travail au sein des territoires métropolitains? Quels en sont les conséquences sur les migrations alternantes? À l’heure où la mobilité constitue à la fois un facteur clé du développement des villes et un enjeu majeur quant aux ’émissions de GES et, alors que le mouvement de déconcentration demeure très actuel et poursuit sa progression, ce mémoire vise à enrichir le débat en proposant une étude basée sur l’analyse des plus récentes formes de distribution des activités métropolitaines en lien avec les caractéristiques de navettage, le tout dans une optique d’évaluation de la durabilité des déplacements. Le cas de Montréal, une métropole dont l’organisation spatiale a été considérée atypique en Amérique du nord, a été observé. L’analyse réalisée comprend trois grandes étapes. L’espace métropolitain montréalais a d’abord fait l’objet d’une caractérisation basée sur une typologie développée en France et basée sur divers critères reliés à la localisation emploi-résidence. Cette typologie a ensuite servi de base à une analyse des déplacements pendulaires, entre 2003 et 2008. Le portrait obtenu a finalement été opposé à celui résultant d’une analyse basée sur un découpage plus traditionnel « centre-banlieue-périphérie » de l’espace métropolitain. Les résultats suggèrent, à l’instar d’autres études, que la seule proximité des lieux d’emploi et de résidence ne suffit pas à favoriser des pratiques de navettage plus durables. D’un point de vue méthodologique, l’étude révèle également la pertinence des deux types d’approches proposés, de même que leur complémentarité.

La desnutrición infantil y la pobreza se encuentran asociadas y estas a su vez con el progreso de los países. Conocer las determinantes sociales y económicas de la niñez que padece de bajo peso es necesario para crear escenarios propicios para el adecuado desarrollo de la primera infancia y de esta manera contribuir con la superación de la pobreza en el marco de sistemas sanitarios equitativos. Se realiza una descripción de las características socio-económicas y un análisis de posibles asociaciones entre estas y el bajo peso infantil de una muestra de infantes de uno de los sectores de mayor vulnerabilidad y pobreza de Bogotá (Colombia). La tasa del bajo peso infantil en la muestra del estudio en más alta a la presentada en Bogotá y Colombia (8.5%, 2.9% y 3.4% respectivamente). Al realizar el análisis de las posibles asociaciones entre el bajo peso y las variables de estudio, se evidencia que las relaciones son débiles entre la primera y las segundas, siendo la condición de desplazamiento la que mayor asociación positiva presenta con la deficiencia nutricional seguido del rango de edad entre los 25 y 36 meses. La situación que presenta mayor independencia con respecto al bajo peso infantil es contar con vivienda propia seguida del sexo. La desnutrición infantil se presenta en niveles importantes en sectores de mayor vulnerabilidad con implicaciones para el adecuado desarrollo de los infantes y para las intenciones de reducción de los índices de pobreza en el país. El fortalecimiento de las políticas públicas que favorezca el desarrollo infantil, la superación de la pobreza y las inequidades en los sistemas de salud deben contemplar acciones integrales dirigidas a los más vulnerables, con la participación de la sociedad civil y los sectores públicos y privados, el compromiso político y económico de los gobiernos y reglas claras que contribuyan a la solución estructural de la pobreza y que promueva el adecuado desarrollo infantil.

En este estudio de caso pretende dar respuesta a que factores vitalizan la cooperación Española en Mozambique a través del análisis de programas como el VITA, dirigidos específicamente al desarrollo y mejoramiento de la salud en el continente Africano. Este estudio de caso se centra en el investigación de los discursos de desarrollo que se fundamentan en las políticas internacionales de cooperación , basadas en la existencia de una enfermedad como el VIH que ha puesto en manifiesto la interacción entre la esfera biológica y social , social e individual entre el fenómeno existencial y cultural, lo que fundamenta su importancia y estudio. Se ha escogido esta herramienta de investigación social, en este estudio de caso, para abordar la forma en que funciona y opera la AECID en Mozambique a través de los programas con enfoque de género encaminados al problema del VIH. Se pretende dar a conocer el desarrollo en materia de la cooperación internacional de una organización tan importante como la AECID, cuyos proyectos gozan de una gran credibilidad en cuanto a la ejecución de sus acciones y que en general dichos proyectos se adecuan a las necesidades de la población, a los objetivos de desarrollo nacionales y a las prioridades de la cooperación española.

For much of the 1990s and 2000s, the emphasis of urban policy in many global cities was on managing and mitigating the social and environmental effects of rapid economic growth. The credit crunch of 2008 and the subsequent recession have undermined some of the core assumptions on which such policies were based. It is in this context that the concept of resilience planning has taken on a new significance. Drawing on contemporary research in London and Hong Kong, the paper shows how resilience and recovery planning has become a key area of political debate. It examines what is meant by conservative and radical interpretations of resilience and how conservative views have come to dominate ‘recovery’ thinking, with élite groups unwilling to accept the limits to the neo-liberal orthodoxies that helped to precipitate the economic crisis. The paper explores the implications of such thinking for the politics of urban development.

The construction sector has a major role to play in delivering the transition to a low carbon economy and in contributing to sustainable development; however, integrating sustainability into everyday business remains a major challenge for the sector. This research explores the experience of three large construction and engineering consultancy firms in mainstreaming sustainability. The aim of the paper is to identify and explain variations in firm level strategies for mainstreaming sustainability. The three cases vary in the way in which sustainability is ramed – as a problem of risk, business opportunity or culture – and in its location within the firm. The research postulates that the mainstreaming of sustainability is not the uniform linear process often articulated in theories of strategic change and management, but varies with the dominant organisational culture and history of each firm. he paper concludes with a reflection on the implications of this analysis for management theories and for firm level strategies.

The impact of 1973–2005 land use–land cover (LULC) changes on near-surface air temperatures during four recent summer extreme heat events (EHEs) are investigated for the arid Phoenix, Arizona, metropolitan area using the Weather Research and Forecasting Model (WRF) in conjunction with the Noah Urban Canopy Model. WRF simulations were carried out for each EHE using LULC for the years 1973, 1985, 1998, and 2005. Comparison of measured near-surface air temperatures and wind speeds for 18 surface stations in the region show a good agreement between observed and simulated data for all simulation periods. The results indicate consistent significant contributions of urban development and accompanying LULC changes to extreme temperatures for the four EHEs. Simulations suggest new urban developments caused an intensification and expansion of the area experiencing extreme temperatures but mainly influenced nighttime temperatures with an increase of up to 10 K. Nighttime temperatures in the existing urban core showed changes of up to 2 K with the ongoing LULC changes. Daytime temperatures were not significantly affected where urban development replaced desert land (increase by 1 K); however, maximum temperatures increased by 2–4 K when irrigated agricultural land was converted to suburban development. According to the model simulations, urban landscaping irrigation contributed to cooling by 0.5–1 K in maximum daytime as well as minimum nighttime 2-m air temperatures in most parts of the urban region. Furthermore, urban development led to a reduction of the already relatively weak nighttime winds and therefore a reduction in advection of cooler air into the city.
