Diagnosing Organizational Identity Beliefs by Eliciting Complex, Multi-Modal Metaphors

The purpose of this article is to extend the organizational development diagnostics repertoire by advancing an approach that surfaces organizational identity beliefs through the elicitation of complex, multimodal metaphors by organizational members. We illustrate the use of such "Type IV" metaphors in a postmerger context, in which individuals sought to make sense of the implications of the merger process for the identity of their organization. This approach contributes to both constructive and discursive new organizational development approaches; and offers a multimodal way of researching organizational identity that goes beyond the dominant, mainly textual modality.

Land Surface Temperature continuous time series from SSM/I passive microwave radiometers, over northern latitudes (Latitudes > 45°N), during summer snow free period (2000-2011), with links to NetCDF files

Remote sensing instruments are key players to map land surface temperature (LST) at large temporal and spatial scales. In this paper, we present how we combine passive microwave and thermal infrared data to estimate LST during summer snow-free periods over northern high latitudes. The methodology is based on the SSM/I-SSMIS 37 GHz measurements at both vertical and horizontal polarizations on a 25 km × 25 km grid size. LST is retrieved from brightness temperatures introducing an empirical linear relationship between emissivities at both polarizations as described in Royer and Poirier (2010). This relationship is calibrated at pixel scale, using cloud-free independent LST data from MODIS instruments. The SSM/I-SSMIS and MODIS data are synchronized by fitting a diurnal cycle model built on skin temperature reanalysis provided by the European Centre for Medium-Range Weather Forecasts (ECMWF). The resulting temperature dataset is provided at 25 km scale and at an hourly time step during the ten-year analysis period (2000-2011). This new product was locally evaluated at five experimental sites of the EU-PAGE21 project against air temperature measurements and meteorological model reanalysis, and compared to the MODIS LST product at both local and circumpolar scale. The results giving a mean RMSE of the order of 2.2 K demonstrate the usefulness of the microwave product, which is unaffected by clouds as opposed to thermal infrared products and offers a better resolution compared to model reanalysis.

Balancing groundwater conservation and rural livelihoods under water and climate uncertainties: An integrated hydro-economic modeling framework

In arid countries worldwide, social conflicts between irrigation-based human development and the conservation of aquatic ecosystems are widespread and attract many public debates. This research focuses on the analysis of water and agricultural policies aimed at conserving groundwater resources and maintaining rurallivelihoods in a basin in Spain's central arid region. Intensive groundwater mining for irrigation has caused overexploitation of the basin's large aquifer, the degradation of reputed wetlands and has given rise to notable social conflicts over the years. With the aim of tackling the multifaceted socio-ecological interactions of complex water systems, the methodology used in this study consists in a novel integration into a common platform of an economic optimization model and a hydrology model WEAP (Water Evaluation And Planning system). This robust tool is used to analyze the spatial and temporal effects of different water and agricultural policies under different climate scenarios. It permits the prediction of different climate and policy outcomes across farm types (water stress impacts and adaptation), at basin's level (aquifer recovery), and along the policies’ implementation horizon (short and long run). Results show that the region's current quota-based water policies may contribute to reduce water consumption in the farms but will not be able to recover the aquifer and will inflict income losses to the rural communities. This situation would worsen in case of drought. Economies of scale and technology are evidenced as larger farms with cropping diversification and those equipped with modern irrigation will better adapt to water stress conditions. However, the long-term sustainability of the aquifer and the maintenance of rurallivelihoods will be attained only if additional policy measures are put in place such as the control of illegal abstractions and the establishing of a water bank. Within the policy domain, the research contributes to the new sustainable development strategy of the EU by concluding that, in water-scarce regions, effective integration of water and agricultural policies is essential for achieving the water protection objectives of the EU policies. Therefore, the design and enforcement of well-balanced region-specific polices is a major task faced by policy makers for achieving successful water management that will ensure nature protection and human development at tolerable social costs. From a methodological perspective, this research initiative contributes to better address hydrological questions as well as economic and social issues in complex water and human systems. Its integrated vision provides a valuable illustration to inform water policy and management decisions within contexts of water-related conflicts worldwide.

Discovery of ferromanganese hydrocarbon-related nodules associated with the Meknes mud volcano (Western Moroccan margin)

A suite of ferromanganese nodules were sampled during the MVSEIS-2008 cruise aboard of the R/V Hespérides in the flanks of Meknes mud volcano (Moroccan margin, NE Central Atlantic). The nodules were collected at water depths between 750-850 m within a seabed area characterized by high acoustic backscatter values. Debris of cold water corals and hydrocarbon-derived authigenic carbonate crusts were sampled at same time. The nodules show tabular morphology, up to 20 cm in maximum diameter and 2 kg of weight, brown-reddish external color and they are internally composed by a concentric to complex arrangement of laminae. The results of X-ray diffraction analysis show that these ferromanganese nodules are essentially composed of goethite and lepidocrocite, being Mn-oxides, silicates (quartz and clay minerals) and carbonates (calcite, dolomite and siderite) accessory to occasional minerals. All the samples display micritic to micro-sparitic mosaic under the petrographic microscope which forms massive, laminated or dendritic-mottled textures. The nodules show a high abundance of Fe, minor Mn and low contents of trace metals and REEs. Mature hydrocarbons, as n-alkanes derived from marine bacterial activity, and phenanthrene have been detected in all the ferromanganese nodules analyzed. These nodules display analogous characteristics (textural, mineralogical and geochemical) to the nodules studied by González et al (2009) in the carbonate mud-mounds in the Gulf of Cadiz, offshore Iberian margin. In this way, the same preliminary genetic model proposed for these nodules might be applicable to those find in the Meknes mud volcano. Therefore, the anaerobic oxidation of hydrocarbon-rich fluids within the mud-breccia sediments in the flanks of Meknes mud volcano would induce the formation of early diagenetic Fe-(Mn) carbonate nodules. Thus, the nodules were later exhumed by the erosive action of sea bottom currents generating the replacement of ferromanganese carbonates by Fe-Mn oxy-hydroxides. Thus, the hydrocarbon-rich fluid venting from deep seated reservoirs and erosive action of bottom currents must have been essential actors, as mineralization controls, for ferromanganese nodules generation and evolution. These findings imply that this type of nodules must be considered as new product as derived from the anaerobic/aerobic oxidation of hydrocarbons in areas of active seepages.

Computer workstation vetting by supply current monitoring

It is our goal within this project to develop a powerful electronic system capable to claim, with high certainty, that a malicious software is running (or not) along with the workstations’ normal activity. The new product will be based on measurement of the supply current taken by a workstation from the grid. Unique technique is proposed within these proceedings that analyses the supply current to produce information about the state of the workstation and to generate information of the presence of malicious software running along with the rightful applications. The testing is based on comparison of the behavior of a fault-free workstation (established i advance) and the behavior of the potentially faulty device.

Validación de un marco abierto accesible de tercera generación para la integración nativa de productos de apoyo en tecnologías de la información y la comunicación

Las personas con discapacidad a menudo se encuentran con problemas de acceso a las Tecnologías de la Información y la Comunicación (TIC), debido a diseños y desarrollos que no tienen en cuenta sus diferencias funcionales, y en consecuencia se encuentran en riesgo de exclusión social. Cada vez es más común encontrar productos de apoyo que permitan utilizar diferentes tecnologías (ordenadores, Internet, dispositivos móviles), pero muchos de ellos no se encuentran integrados debido a que funcionan esencialmente modificando la plataforma donde están instalados, siendo soluciones de acceso de segunda generación. Más allá del desarrollo de los productos de apoyo, que sin duda ha evolucionado positivamente en los últimos años, cabe resaltar que existe una falta de herramientas y de aproximación holística que ayuden a los desarrolladores y diseñadores hacer las TIC accesibles. Esta tesis doctoral pretende validar la hipótesis de que una metodología holística de desarrollo de aplicaciones y productos de apoyo TIC, llamada Marco Abierto Accesible, facilita el desarrollo y la integración de modo nativo de la accesibilidad en las aplicaciones y productos apoyo, independientemente de la tecnología utilizada, dando lugar a soluciones de acceso de tercera generación que permitan mejorar la utilización de dichas aplicaciones por parte de personas con discapacidad. Este trabajo se ha desarrollado en el marco del proyecto AEGIS (del inglés, open Accessibility Everywhere: Groundwork, Infrastructure, Standards), que fue parcialmente financiado por la Comisión Europea (CE) bajo el VII Programa Marco y tuvo una duración de cuatro años. La metodología para el diseño, desarrollo y validación seguida en esta tesis es una adaptación de dos metodologías de diseño existentes (el Diseño Centrado en el Usuario y el Diseño Orientado a Metas), la implementación del Marco Abierto Accesible y el uso de diferentes técnicas de validación. Además se ha desarrollado un marco metodológico de entrenamiento para minimizar el efecto que tiene la curva de aprendizaje cuando los usuarios prueban por primera vez las soluciones desarrolladas. En esta tesis se presenta el Marco Abierto Accesible aplicado a las TIC en las tres áreas en las que se desarrolla este trabajo: ordenadores, Internet y dispositivos móviles, partiendo de las necesidades y problemas que tienen los usuarios con discapacidad en el uso de las TIC. Diferentes instanciaciones del Marco Abierto Accesible se definen en las tres áreas TIC mencionadas anteriormente y se describen varios ejemplos de sus implementaciones particulares. Los resultados de las evaluaciones de las implementaciones particulares con usuarios finales y expertos, una vez discutidos y contrastados con las hipótesis, sirven para probar la validez del Marco Abierto Accesible para la integración nativa de productos de apoyo en Tecnologías de la Información y la Comunicación. Finalmente, se presentan las líneas de investigación y trabajo futuro en el área de la accesibilidad en las TIC. ABSTRACT People with disabilities often encounter problems of access to Information and Communications Technology (ICT), due to design and developments that do not take into account their functional differences and therefore put them at risk of social exclusion. It is increasingly common to find assistive products that allow to use different technologies (computers, Internet, mobile devices), but many of them are not well integrated because they work essentially modifying the platform where they are installed, beeing the second-generation access solutions. Beyond the assistive product development, which has certainly evolved positively in recent years, it is notable that there is a lack of tools and holistic approach to help developers and designers make accessible ICT. This doctoral thesis aims to validate the hypothesis that a holistic approach to application development and assistive ICT products, called Open Accessibility Framework, facilitates the development and integration of native accessible applications and assistive products, regardless of the technology used, resulting in third-generation access solutions that improve the use of such applications by people with disabilities. This work was developed under the AEGIS project (open Accessibility Everywhere: Groundwork, Infrastructure, Standards), which was partially funded by the European Commission (EC) under the Seventh Framework Programme and lasted four years. The methodology for the design, development and validation followed in this thesis is an adaptation of two existing design methodologies (User Centered Design and Goal Oriented Design), the implementation of the Open Accessibility Framework and the usage of different validation techniques. A training methodological framework ha also been developed to minimize the effect of the learning curve when users first try the solutions developed. This thesis presents the Open Accessibility Framework applied to ICT in three areas in which this work is developed: computers, Internet and mobile devices, based on the needs and problems of the disabled users in the use of ICT. Different instantiations of the Open Accessibility Framework are defined in the three aforementioned ICT areas and various examples of its particular implementations are described. The results of the evaluations of the particular implementations which have been carried with end users and experts, once discussed and contrasted with the hypotheses, have been used to test the validity of the Open Accessibility Framework for the native integration of assistive products in Information and Communications Technology. Finally, the future research lines and future work in the area of ICT accessibility are presented.

Antiguo Poblado de Algarrobito ubicado en el Valle del Elqui Chile, y su Patrón Urbano Bioclimático

La importancia de conocer bien el entorno para un proyecto arquitectónico es que podemos adaptarlo a nuestras necesidades fisiológicas de Confort Térmico. Podemos decir entonces que el edificio juega un papel fundamental como técnica de control de nuestro entorno. El edificio nos debería entregar un entorno controlado para que nos sintamos bien térmicamente, considerando además, que la arquitectura por sí misma puede lograr dicho confort la mayor parte de las veces. De no ser así, los usuarios tienden a colocar elementos mecánicos, para generar frío o calor artificialmente. Es fundamental entonces que nuestros edificios, tengan una correcta interacción con los recursos naturales del lugar para lograr dicho confort térmico. Pero lograr el Confort Térmico en todos los edificios de una ciudad como unidad, no logrará que la ciudad entera sea confortable térmicamente, ya que las complejas interacciones hacen que la problemática se deba enfrentar como algo sistémico. Esto quiere decir, que para que una ciudad o un conjunto logren la Confortabilidad Térmica deseada por sus habitantes debiera haber sido planificada conforme a variables urbanas que interactúen con el medio natural en forma eficiente. Con la observación de ciertos conjuntos habitacionales antiguos en el interior del Valle del Elqui, Chile y de sus relaciones entre variables urbanas y naturales, queda de manifiesto ciertas características que conllevan a pensar que existió una planificación ambiental en éstos que llevaron a lograr un conjunto con características bioclimáticas. Las evidencias de la existencia en primer lugar de un patrón urbanístico en dichos conjuntos habitacionales antiguos, hacen pensar que dicho patrón se trataría de un patrón bioclimático rural planificado, lo que hace que exista un gran interés por el estudio de estos conjuntos. Hasta ahora, en Chile, los pocos estudios de Confort Térmico que existen, están orientados a edificaciones aisladas, al Confort térmico interior de la edificación en el ámbito urbano, y en nada a Patrones Bioclimáticos de Conjuntos Habitacionales en una situación de ruralidad como a la referida en esta investigación. Además, los estudios referidos al clima urbano, difieren a los del clima rural, por lo que se necesitan mayores estudios aún para comprender mejor la problemática. Es por esto, que la mayoría de los casos mencionados en este estudio son contextualizados al ámbito urbano por carecer de otros estudios rurales. Es en este sentido que esta investigación cobra real importancia y pretende establecer la relación existente entre las variables morfológicas rurales y los recursos naturales del lugar y que generan un confort térmico ideal para sus habitantes, al mismo tiempo, se analiza la existencia de un Patrón Bioclimático en un poblado denominado Algarrobito ubicado en la cuenca del Valle del Elqui, Chile. Es en este sentido que el propósito principal de este trabajo es determinar la real existencia de un Patrón Bioclimático que relacione la morfología rural y edificada de los antiguos poblados pertenecientes a la cuenca del Valle de Elqui Chile con el microclima del lugar. La metodología empleada se basa en realizar primeramente el estudio del microclima del lugar a través de las Cartas Bioclimáticas. Para ello se obtuvo información de datos climatológicos de las estaciones meteorológicas ubicadas en la cuenca del Valle de Elqui, principalmente las más cercanas al lugar de estudio. Mediante una revisión exhaustiva de la información arquitectónica, así como de una labor de reconocimiento en terreno realizada en el poblado seleccionado y de la aplicación del Climograma local, se identificaron las diferentes zonas bioclimáticas del poblado antiguo y potenciales áreas de estudio en el conjunto. Esta actividad incluyó un estudio preliminar de la energía solar local, vientos, humedad, temperaturas y su interacción con el conjunto, permitiendo una primera aproximación a la problemática del espacio exterior y las viviendas. Esto permitió en base a las condicionantes del lugar, la arquitectura vernácula y los materiales descubrir un Patrón en el antiguo conjunto que permitía entregar confortabilidad térmica a sus habitantes y darse cuenta también, que el nuevo conjunto emplazado en el sector no seguía ese patrón con las disfuncionalidades que ello llevaba. Con esto quedó demostrado en primer lugar la existencia de un Patrón Bioclimático rural, los beneficios del patrón, la importancia de éste como causante de Confortabilidad Térmica del conjunto, y por ende de mejor eficiencia energética, así como también, que el nuevo conjunto no sigue para nada este Patrón, pero que existe también la posibilidad de rectificación y por supuesto, que los nuevos desarrollos residenciales del Valle del Elqui, puedan planificarse en base al patrón bioclimático descubierto. ABSTRACT Knowing the environment of an architectonic proyect is really important for adjusting it to our physiological needs of Thermal Comfort. So we can say that the building plays a key role as a technique of control of our environment. The building should give us a controlled environment to make us feel good thermally, and it usually can reach pleasurable temperatures by itself. If it isn't like that, people cooled or heated the ambience with mechanical elements. So a correct interaction between the buildings and natural resources is important to reach a thermal comfort. But achieving Thermal Comfort in all the buildings of a city as a unit will not achieve the whole city is thermally comfortable, because the complex interactions cause the problem needs to be solved as something systemic. This means that for a city or a set reach the Thermal Comfortability desired by its inhabitants, it should have been planned according to the urban variables that interact with the natural environment efficiently. Observing some old housing complexes in Elqui Valley, Chile, and the relationships between their natural and urban variables, some features lead to think that the environmental planning in these led to achieve a set with bioclimatic features. First, the evidences about the existence of an urban pattern in those old housing complexes, make thinking that the pattern would be a planned urban pattern, which generates interest in its study. In Chile, there have been few studies about Thermal Comfort, oriented to isolated buildings and indoor thermal comfort, but Bioclimatic Urban Patterns haven't been studied at all. In this sense, this investigation acquires a real importance and pretends to establish the relationship between urban variables and natural resources of the place that generates a good thermal comfort for its habitants. At the same time, the existence of a Bioclimatic Urban Pattern in Algarrobito, located in Elqui Valley basin, Chile, is analized. It is in this sense that the main purpose of this work is to determine the real existence of a Bioclimatic Urban Pattern, that links the urban and constructive form of the old villages of it with its microclimate. The methodology used is based on performing first the study of the microclimate of the place through the Bioclimatic Cards. To do this, weather stations, located in Elqui valley, near the place that was studied, were used to obtain information of climatological data. The different bioclimatic zones to the old town and potential areas of study in the set were identified, through an exhaustive review of the architectural information, a field reconnaissance work performed on the selected town and the application of the Local Climograph. This activity included a preliminary study of the local solar energy, the winds, the moisture, the temperatures, and their interaction with the set, allowing a first aproximation to troubles of outer space and housing. This allowed, based on the conditions of the place, vernacular architecture and materials, discovering an urban pattern in the old set, which allowed to give thermal comfort to its inhabitants and realize that the new set of the place did not follow this pattern, with the dysfunctions that it carried. These points demonstrated, in first place, the existence of a Bioclimatic Urban Pattern, the benefits of it, the importance of it as a cause of Thermal Comfortability, and therefore a better efficiency of energy, also that the new set doesn’t follow this Pattern at all, but that the posibility of rectification exists and, of course, that the new residencial development in Elqui Valley can be planned based on bioclimatic pattern discovered.

Expansión y transformación del territorio : la ineficiencia de los fraccionamientos urbanizados : zona conurbada de Veracruz, México

La expansión de la ciudad y zona conurbada de Veracruz, se encuentra en una dinámica en donde convergen el medio artificial construido por el hombre y que ha generado una ciudad fragmentada; el medio natural, en el que se encuentran importantes componentes ecosistémicos de la zona costera; las políticas y estrategias que establecen los cinco Programas de ordenamiento urbano vigentes, sujetos al patrón de acumulación de capital, favoreciendo los intereses de la iniciativa privada. Bajo este panorama encontramos un territorio complejo que se encuentra cada vez más vulnerado y en riesgo de que los sistemas humano y natural colapsen. Lo anterior se evidencia en los nuevos desarrollos urbanizados, a partir del estudio de la problemática que presentan los fraccionamientos habitacionales, donde cada vez son más vulnerables, lo que constata su ineficiencia dentro del sistema urbano. ABSTRACT The expansion of the city and metropolitan area of Veracruz, is in a dynamic where converge the artificial environment built by the man and that has generated a fragmented city; natural environment, in which there are important ecosystem components of the coastal zone; policies and strategies that establish the five existing urban planning programs, subject to the pattern of accumulation of capital, favoring the private enterprises interests. Under this scenario is found a complex area that is more vulnerable every time and at risk of human and natural systems collapse. The above mentioned is evident in the new urbanized development, from studies of the problem posed by housing developments, finding that more and more vulnerable, which finds its inefficiency within the urban system.

The role of voice input for human-machine communication.

Optimism is growing that the near future will witness rapid growth in human-computer interaction using voice. System prototypes have recently been built that demonstrate speaker-independent real-time speech recognition, and understanding of naturally spoken utterances with vocabularies of 1000 to 2000 words, and larger. Already, computer manufacturers are building speech recognition subsystems into their new product lines. However, before this technology can be broadly useful, a substantial knowledge base is needed about human spoken language and performance during computer-based spoken interaction. This paper reviews application areas in which spoken interaction can play a significant role, assesses potential benefits of spoken interaction with machines, and compares voice with other modalities of human-computer interaction. It also discusses information that will be needed to build a firm empirical foundation for the design of future spoken and multimodal interfaces. Finally, it argues for a more systematic and scientific approach to investigating spoken input and performance with future language technology.

Experiências de uma comunidade de prática sobre desenvolvimento de produtos: iniciativas e tecnologia promovendo aprendizagem e criação de conhecimentos

O processo de desenvolvimento de produto é reconhecido pela literatura como sendo de importância estratégica, mas, apesar disso, existe uma grande dificuldade para se gerenciar este processo, devido a existência de diversas visões parciais sobre sua abrangência e importância, as quais dificultam a integração entre os profissionais que atuam nessa área. No campo de ensino e pesquisa esse fenômeno também ocorre, pois o desenvolvimento de produtos é tratado de maneira incompleta pelas diferentes áreas de conhecimento especializado, criando visões parciais que apresentam linguagem e características próprias, as quais dificultam um entendimento comum dos aspectos desse processo. Para enfrentar esta situação, esse trabalho apresenta a experiência de grupos de pesquisa que formaram uma comunidade de prática em desenvolvimento de produtos, chamada PDPNet (Product Development Process Network), visando minimizar essas visões parciais. Para isso, os membros de tal comunidade envolveram-se no desenvolvimento de iniciativas e atividades conjuntas e têm a sua disposição um portal de conhecimentos para favorecer a sinergia entre os membros, apoiando o ambiente voltado à cooperação e facilitando a troca e criação de conhecimentos, o que é objetivo primordial de uma comunidade de prática. Este trabalho visa relatar e analisar criticamente as características principais da PDPNet, enfocando sua formação, estabelecimento, gestão das iniciativas e atividades para criação de conhecimentos, bem como a tecnologia de informação utilizada. Com esse trabalho, espera-se divulgar essa experiência para o meio acadêmico e empresarial interessado, de forma que suas práticas possam ser propagadas e as dificuldades consideradas. Além disso, espera-se que a análise crítica permita obter subsídios para que seus principais benefícios e dificuldades possam ser identificados e tratados pelos gestores da comunidade.

Projeto e testes de uma churrasqueira a etanol com queimadores infravermelhos.

Atualmente, há poucas aplicações de uso de combustíveis renováveis em queimadores, apesar de representarem grande parte do consumo de energia primária. O etanol se apresenta como uma alternativa com grande potencial para substituição de combustíveis não-renováveis em queimadores no Brasil. Tendo em vista este potencial, foi realizado um estudo de possíveis aplicações de queimadores a etanol, com potência inferior a 50 kW, do ponto de vista ambiental, econômico e tecnológico. Foi selecionada uma churrasqueira como a aplicação mais viável. Tendo em vista a necessidade de troca de calor por radiação, foram selecionados queimadores porosos infravermelhos em conjunto com bicos pulverizadores. Durante os testes, a combustão incompleta com gotejamento de combustível se mostrou um problema freqüente. Foi construída uma série de protótipos até se chegar a uma solução final do problema. Este protótipo final, com itens de baixo custo, foi testado avaliando-se potência e emissões, apresentando performance adequada. Foram também estabelecidas diretrizes para desenvolvimento de um produto.

Sustainable materials: The business case for green chemistry design practices

Product manufacturers face increasing environmental and human health regulations with certain regulations targeting specific chemicals of concern that must be removed from the supply chain. This study examines a green chemistry approach to choosing between flame retardant alternatives in electronic products during the design phase of product development. An aggregated score based on five criteria was generated for each flame retardant. To address subjectivity and cognitive bias concerns probabilistic sensitivity analysis was applied to the weighting factors used to generate the scores to examine the reliability of the results. The highest scoring flame retardants based on the comprehensive green chemistry approach were different from the flame retardants chosen using cost as the primary selection criteria.
