Data mining applied to the cognitive rehabilitation of patients with acquired brain injury

Acquired brain injury (ABI) is one of the leading causes of death and disability in the world and is associated with high health care costs as a result of the acute treatment and long term rehabilitation involved. Different algorithms and methods have been proposed to predict the effectiveness of rehabilitation programs. In general, research has focused on predicting the overall improvement of patients with ABI. The purpose of this study is the novel application of data mining (DM) techniques to predict the outcomes of cognitive rehabilitation in patients with ABI. We generate three predictive models that allow us to obtain new knowledge to evaluate and improve the effectiveness of the cognitive rehabilitation process. Decision tree (DT), multilayer perceptron (MLP) and general regression neural network (GRNN) have been used to construct the prediction models. 10-fold cross validation was carried out in order to test the algorithms, using the Institut Guttmann Neurorehabilitation Hospital (IG) patients database. Performance of the models was tested through specificity, sensitivity and accuracy analysis and confusion matrix analysis. The experimental results obtained by DT are clearly superior with a prediction average accuracy of 90.38%, while MLP and GRRN obtained a 78.7% and 75.96%, respectively. This study allows to increase the knowledge about the contributing factors of an ABI patient recovery and to estimate treatment efficacy in individual patients.

Improving brain injury cognitive rehabilitation by personalized telerehabilitation services: Guttmann neuropersonal trainer

Cognitive rehabilitation aims to remediate or alleviate the cognitive deficits appearing after an episode of acquired brain injury (ABI). The purpose of this work is to describe the telerehabilitation platform called Guttmann Neuropersonal Trainer (GNPT) which provides new strategies for cognitive rehabilitation, improving efficiency and access to treatments, and to increase knowledge generation from the process. A cognitive rehabilitation process has been modeled to design and develop the system, which allows neuropsychologists to configure and schedule rehabilitation sessions, consisting of set of personalized computerized cognitive exercises grounded on neuroscience and plasticity principles. It provides remote continuous monitoring of patient's performance, by an asynchronous communication strategy. An automatic knowledge extraction method has been used to implement a decision support system, improving treatment customization. GNPT has been implemented in 27 rehabilitation centers and in 83 patients' homes, facilitating the access to the treatment. In total, 1660 patients have been treated. Usability and cost analysis methodologies have been applied to measure the efficiency in real clinical environments. The usability evaluation reveals a system usability score higher than 70 for all target users. The cost efficiency study results show a relation of 1-20 compared to face-to-face rehabilitation. GNPT enables brain-damaged patients to continue and further extend rehabilitation beyond the hospital, improving the efficiency of the rehabilitation process. It allows customized therapeutic plans, providing information to further development of clinical practice guidelines.

Las capacidades de los actores para dirigir la nueva gobernanza en el desarrollo rural en México

El objetivo de la presente investigación es analizar el proceso de implantación de la nueva gobernanza dirigido por diferentes actores, en contextos rurales de Chiapas, México, que permita generar aportes conceptuales y propuestas de acción pública para su gestión. En la presente investigación se desarrollaron tres estudios de caso con un enfoque comparativo. Cada caso tuvo un actor diferente que dinamizó el proceso, en el primero fue el privado empresarial, en el segundo la sociedad civil y en el tercero el gobierno local. Lo registrado en la presente investigación señala que la nueva gobernanza no se acota a lo definido por organismos externos al territorio y tampoco se arriba a través de una sola ruta, se estructura fundamentalmente por lo que los mismos actores locales trabajen mediante un proceso de aprendizaje social en su definición y proceso de cambio según sus elementos socio-culturales. La nueva gobernanza dirigida por la sociedad civil es quien tuvo los mejores resultados respecto a los casos guiados por la iniciativa privada y el gobierno local. Sin embargo, es este último actor quien tiene las mayores posibilidades de detonar los procesos de nueva gobernanza en la mayoría de los contextos territoriales para dar paso a la sociedad civil o la iniciativa privada que posibiliten la sostenibilidad de los procesos en el largo plazo. The purpose of the current research is to analyze the new governance implantation process directed by different actors, in the rural contexts of Chiapas, México which will permit to generate conceptual contributions and public action proposals for its management. In the current research three case studies were developed each one based on comparative focus. Each case had a different actor which put into effect such process. In the first case it was private business, in the second the civilian society and in the third the local government. The information that was registered in the current research points out that the new governance do not encloses to elements defined by those organisms which are external to the territory and neither arrives through a single pathway; it is fundamentally structured and for this reason the same local actors work through a social learning process in its definition and change process in accordance to the socio-cultural elements. The new governance which is directed by the civilian society is the one that had the best results regarding the cases that were guided by the private sector and the local government. Nevertheless, this last actor is the one who had the best chances to trigger the new governance processes in most of the territorial contexts yielding the civilian society or private business to enable the long term processes sustainability.

Arquitecturas desplazadas. Rafael Bergamín y las arquitecturas del exilio español en Venezuela

El siglo XX ha sido el siglo de los desplazamientos. Una ingente cantidad de personas fueron forzadas por motivos políticos, o se vieron obligadas por motivos económicos, a abandonar sus territorios de origen, generando un distanciamiento que en la mayoría de los casos resultaría irrecuperable. Las penurias vividas en Europa, las oportunidades que se abrían en países americanos, o la presión ejercida por los regímenes totalitarios, llevaron a un buen número de profesionales, artistas e intelectuales europeos a territorio americano. El presente trabajo se propone indagar sobre una de esas migraciones que se establecieron en Latinoamérica en la primera mitad del siglo XX: la de los arquitectos españoles que se vieron forzados al exilio. Para ello se busca poner en evidencia no sólo sus aportaciones sino también la influencia que ejerció en su obra la cultura de los países de adopción. Venezuela recibió gran parte del contingente de arquitectos españoles desplazados como consecuencia de la Guerra Civil. Tras México fue el país que mayor número acogió. La llegada de dichos exiliados coincidió con el momento en que la sociedad venezolana, de base agrícola y comercial, pasaría a evidenciar el impacto de la revolución petrolera. Así pues, dicha llegada supuso no sólo la dramática pérdida del mundo previo, implícita en todo exilio, sino el arribo a una sociedad en profundo proceso de cambio. En ambos casos se trataba de “mundos que se desvanecen”. Se propone la asunción de la obra de dichos profesionales como una arquitectura desplazada. Un desplazamiento que se produce en dos sentidos: por un lado, se trata de un desplazamiento físico, por otro, la palabra desplazada habla también de la condición secundaria que adquiere la arquitectura ante el drama vital y de supervivencia que afectó a los exiliados. Así pues, a un desplazamiento físico, verificable, se une un desplazamiento en cuanto al nivel de importancia y de atención asignado a la arquitectura. El trabajo comprende una introducción, cuatro capítulos, y un epílogo, a modo de conclusión. A lo largo de dichos capítulos se conjugan el enfoque individual en la obra de uno de estos arquitectos desterrados, Rafael Bergamín, y la visión “coral” de diversas trayectorias vitales que enfrentaron un destino común. Se elige la figura de Bergamín como eje de desarrollo debido a la presencia significativa que tuvo su obra tanto en España como en Venezuela, y por la caracterización de la misma como obra construida en colaboración. La introducción, “Exilios arquitectónicos”, muestra el sustrato estructural, la fundamentación y la metodología empleada, incluyendo “problematizaciones” sobre el exilio arquitectónico. El primer capítulo, “Memoria de partida”, da cuenta de la formación y actuación, durante la preguerra, de los arquitectos españoles que saldrían al exilio. Se introduce un esquema de base generacional y se revela un panorama para nada unívoco. El segundo capítulo, “Guerra y salida al exilio”, aborda la actuación de dichos arquitectos durante la contienda bélica así como la posterior dispersión general del exilio. El tercer capítulo, “Construir desde lo que se desvanece. Arquitectos del exilio español en Venezuela”, propone diversos presupuestos conceptuales en torno al tema del desplazamiento en la arquitectura, revisando la adscripción disciplinar y profesional de los arquitectos españoles exiliados en Venezuela. El cuarto capítulo, “El regreso”, versa sobre el recorrido final de estos arquitectos. Como marco general, se revisa su itinerario de regreso o, en muchos casos, la imposibilidad de retorno. Por último, se dispone la fuente de los diversos documentos de archivos y repositorios, así como el aparato bibliográfico y referencial, empleados en la investigación. Tres anexos se adjuntan al corpus del trabajo. El primero presenta documentos inéditos, hallados durante el pertinente proceso de investigación; el segundo, dibujos de Bergamín, básicamente de las primeras décadas del siglo XX: caricaturas, anuncios y trabajos de la Escuela; el tercero, un esbozo biográfico de los arquitectos del exilio español. ABSTRACT The 20th Century has been the century of displacements. An enormous number of people were forced to leave their homelands for political or economic reasons, which generated a gap that in most of the cases would be unrecoverable. The hardships that people had to endure in Europe, the opportunities that emerged in American countries, or the pressure exerted by totalitarian regimes drove a good number of European professionals, artists and intellectuals to American territory. This research study is intended to investigate one of those migrations that settled in Latin America during the first half of the 20th century: the one of the Spanish architects that were forced into exile. To achieve this, an attempt was made to expose not only their contributions but also the influence that the culture of the countries which welcomed them exerted in their work. Venezuela received a large portion of Spanish architects who were displaced as a consequence of the Civil War. After Mexico, it was the country that sheltered the greatest number of persons. The arrival of these exiled Spanish architects coincided with the moment in which the Venezuelan society – based on agriculture and commerce – would witness the impact of the revolution of the oil industry. Thus, their arrival supposed not only experiencing the dramatic loss of their previous world – implicit in the notion of the exile – but also settling in a society going through a profound change process. In both cases it was about “two worlds that were vanishing.” The assumption of these architects’ work is regarded as a displaced architecture. A displacement that takes place in two ways: on one hand, there was a physical displacement, and on the other hand, the word displaced also talks about the second place that architecture is given when confronted with the urgent drama of survival that affected the exiled community. Hence, a physical, verifiable displacement is combined with a displacement that has to do with the importance and the attention given to architecture. This research study encompasses an introduction, four chapters, and an epilogue as a conclusion. Throughout the chapters, the individual approach to the work of one of these exiled architects, Rafael Bergamín, runs in parallel to an overall view of various other architects’ career paths that faced a common destiny. The work of the architect Bergamín was chosen as the center of this research study due to the significant presence that his work had in Spain as well as in Venezuela, and because its main characteristic was that it was built in collaboration with other architects. The introduction, “Architectural exiles”, shows the structural contextualization, the explanatory thesis statement and the methodology used, including “problematizations” about the architectural exile. The first chapter, “Memory of departure”, contains the academic background and performance during the pre-war time of the Spanish architects that would go into exile. An outline based on different generations and revealing an unambiguous perspective is introduced. The second chapter, “War and departure into exile”, tackles the performance of the Spanish architects during the war, as well as the following general diaspora into exile. The third chapter, “Building from what vanishes. Architects of the Spanish exile in Venezuela”, proposes various conceptual assumptions concerning the topic of displacement in architecture according to the doctrine and professional affiliations of the Spanish architects exiled in Venezuela. The fourth chapter, “The return”, deals with the end of these architects’ careers. As a general framework, their itineraries to return, or in many cases, the impossibility of returning, are reviewed. Finally, the sources to the various documents of files and repositories, as well as the bibliographical references consulted for the research, are provided. Three annexes have been attached to this research study. The first annex contains unpublished documents found during the research process; the second includes Bergamín’s drawings, basically from the first decades of the 20th century, such as, caricatures, advertisements and assignments done when he was a university student; and the third annex presents a biographical outline of the architects of the Spanish exile.

Agile it project management professional

La gestión de las tecnologías de la información tiene cada vez más importancia dentro de un mundo totalmente digitalizado y donde la capacidad de respuesta al cambio puede marcar el devenir de una compañía, y resulta cada vez más evidente que los modelos de gestión tradicionales utilizados en la mayoría de las compañías no son capaces de dar respuesta por si solos a estas nuevas necesidades. Aun teniendo identificado este área de mejora, son muchas las empresas reacias a abordar estos cambios, principalmente por el cambio rupturista que significa a nivel interno. De cara a facilitar esta transformación, se propone en este documento un modelo de transición controlada donde las grandes compañías puedan incorporar nuevas alternativas y herramientas ágiles de forma paulatina y asegurando que el proceso de cambio es seguro y efectivo. Mediante una modificación del ciclo de vida de proyecto dentro de la compañía, se incorporan en las áreas, equipos o dominios de la empresa que se identifiquen los nuevos modelos de gestión ágil, permitiendo así una transición gradual y controlada, y pudiendo además analizar los detalles sobre todo en etapas tempranas de la transformación. Una vez seleccionada el área o dominio objeto de la transformación, se realiza un análisis a nivel de Portfolio de proyectos, identificando aquellos que cumplen una serie de condiciones que les permiten ser gestionados utilizando modelos de gestión ágil. Para ello, se plantea una matriz de decisión con las principales variables a tener en cuenta a la hora de tomar una decisión. Una vez seleccionado y consensuado con los interesados el modelo de gestión utilizando la matriz de decisión, se plantean una serie de herramientas y métricas asociadas para que la gestión ágil del proyecto dé una visibilidad completa y detallada del estado en cada momento, asegurando un correcto proceso de gestión de proyectos para proveer visibilidad regular del progreso, riesgos, planes de contingencia y problemas, con las alertas y escalaciones adecuadas. Además de proponerse una serie de herramientas y métricas para la gestión ágil del proyecto, se plantean las modificaciones necesarias sobre las tipologías habituales de contrato y se propone un nuevo modelo de contrato: el Contrato Agile. La principal diferencia entre este nuevo modelo de contrato y los habituales es que, al igual que las metodologías ágiles, es ejecutado en segmentos o iteraciones. En definitiva, el objetivo de este documento es proveer un mecanismo que facilite la inclusión de nuevos modelos ágiles de gestión en grandes organizaciones, llevando a cabo una transición controlada, con herramientas y métricas adaptadas para tener visibilidad completa sobre los proyectos en todo momento.---ABSTRACT---The information technology management is every time more important in a totally digitized world, where the capacity to response the change could mark the future of a company, and results every time more evident that the traditional management models used in the most of the companies are not able to respond by themselves to these new necessities. Even having identified this improvement area, many companies are reluctant to address these changes, mainly due to the disruptive change that it means internally in the companies. In order to facilitate this transformation, this document proposed a controlled transition model to help the big companies to incorporate new alternatives and agile tools gradually and ensuring that the change process is safe and effective. Through a modification the project life cycle inside the company, the new agile management models are incorporated in the selected areas, teams or domains, permitting a gradual and controlled transition, and enabling further analyze the details above all in the early phases of the transformation. Once is selected the area or domain object of the transformation, a portfolio level analysis is performed, identifying those projects that meet a some conditions that allow them to be managed using agile management models. For that, a decision matrix is proposed with the principal variables to have into account at the time of decision making. Once the management model is selected using the decision matrix and it is agreed with the different stakeholders, a group of tools and metrics associated with the agile management projects are proposed to provide a regular visibility of the project progress, risks, contingency plans and problems, with proper alerts and escalations. Besides the group of tools and metrics proposed for agile project management, the necessary modifications over the traditional contract models and a new contract model are proposed: the Agile Contract. The main difference between this new contract model and the traditional ones is that, as the agile methodologies, it is executed in segments or iterations. To sum up, the objective of this document is to provide a mechanism that facilitates the inclusion of new agile management models in big companies, with a controlled transition and proposing adapted tools and metrics to have a full visibility over the project in all the phases of the project life cycle.

Modelado y Evaluación de Entornos Virtuales Interactivos para Rehabilitación Cognitiva en Daño Cerebral

El Daño Cerebral (DC) se refiere a cualquier lesión producida en el cerebro y que afecta a su funcionalidad. Se ha convertido en una de las principales causas de discapacidad neurológica de las sociedades desarrolladas. Hasta la más sencilla de las actividades y acciones que realizamos en nuestro día a día involucran a los procesos cognitivos. Por ello, la alteración de las funciones cognitivas como consecuencia del DC, limita no sólo la calidad de vida del paciente sino también la de las persona de su entorno. La rehabilitación cognitiva trata de aumentar la autonomía y calidad de vida del paciente minimizando o compensando los desórdenes funciones causados por el episodio de DC. La plasticidad cerebral es una propiedad intrínseca al sistema nervioso humano por la que en función a la experiencia se crean nuevos patrones de conectividad. El propósito de la neurorrehabilitación es precisamente modular esta propiedad intrínseca a partir de ejercicios específicos, los cuales podrían derivar en la recuperación parcial o total de las funciones afectadas. La incorporación de la tecnología a las terapias de rehabilitación ha permitido desarrollar nuevas metodologías de trabajo. Esto ha ayudado a hacer frente a las dificultades de la rehabilitación que los procesos tradicionales no logran abarcar. A pesar del gran avance realizado en los Ãoltimos años, todavía existen debilidades en el proceso de rehabilitación; por ejemplo, la trasferencia a la vida real de las habilidades logradas durante la terapia de rehabilitación, así como su generalización a otras actividades cotidianas. Los entornos virtuales pueden reproducir situaciones cotidianas. Permiten simular, de forma controlada, los requisitos conductuales que encontramos en la vida real. En un contexto terapéutico, puede ser utilizado por el neuropsicólogo para corregir en el paciente comportamientos patológicos no deseados, realizar intervenciones terapéuticas sobre Actividades de Vida Diaria que estimulen conductas adaptativas. A pesar de que las tecnologías actuales tienen potencial suficiente para aportar nuevos beneficios al proceso de rehabilitación, existe cierta reticencia a su incorporación a la clínica diaria. A día de hoy, no se ha podido demostrar que su uso aporte una mejorar significativa con respecto a otro tipo de intervención; en otras palabras, no existe evidencia científica de la eficacia del uso de entornos virtuales interactivos en rehabilitación. En este contexto, la presente Tesis Doctoral trata de abordar los aspectos que mantienen a los entornos virtuales interactivos al margen de la rutina clínica diaria. Se estudian las diferentes etapas del proceso de rehabilitación cognitiva relacionado con la integración y uso de estos entornos: diseño de las actividades, su implementación en el entorno virtual, y finalmente la ejecución por el paciente y análisis de los respectivos datos. Por tanto, los bloques en los que queda dividido el trabajo de investigación expuesto en esta memoria son: 1. Diseño de las AVD. La definición y configuración de los elementos que componen la AVD permite al terapeuta diseñar estrategias de intervención terapéutica para actuar sobre el comportamiento del paciente durante la ejecución de la actividad. En esta parte de la tesis se pretende formalizar el diseño de las AVD de tal forma que el terapeuta pueda explotar el potencial tecnológico de los entornos virtuales interactivos abstrayéndose de la complejidad implícita a la tecnología. Para hacer viable este planteamiento se propone una metodología que permita modelar la definición de las AVD, representar el conocimiento implícito en ellas, y asistir al neuropsicólogo durante el proceso de diseño de la intervención clínica. 2. Entorno virtual interactivo. El gran avance tecnológico producido durante los Ãoltimos años permite reproducir AVD interactivas en un contexto de uso clínico. El objetivo perseguido en esta parte de la Tesis es el de extraer las características potenciales de esta solución tecnológica y aplicarla a las necesidades y requisitos de la rehabilitación cognitiva. Se propone el uso de la tecnología de Vídeo Interactivo para el desarrollo de estos entornos virtuales. Para la evaluación de la misma se realiza un estudio experimental dividido en dos fases con la participación de sujetos sanos y pacientes, donde se valora su idoneidad para ser utilizado en terapias de rehabilitación cognitiva. 3. Monitorización de las AVD. El uso de estos entornos virtuales interactivos expone al paciente ante una gran cantidad de estímulos e interacciones. Este hecho requiere de instrumentos de monitorización avanzado que aporten al terapeuta información objetiva sobre el comportamiento del paciente, lo que le podría permitir por ejemplo evaluar la eficacia del tratamiento. En este apartado se propone el uso de métricas basadas en la atención visual y la interacción con el entorno para conocer datos sobre el comportamiento del paciente durante la AVD. Se desarrolla un sistema de monitorización integrado con el entorno virtual que ofrece los instrumentos necesarios para la evaluación de estas métricas para su uso clínico. La metodología propuesta ha permitido diseñar una AVD basada en la definición de intervenciones terapéuticas. Posteriormente esta AVD has sido implementada mediante la tecnología de vídeo interactivo, creando así el prototipo de un entorno virtual para ser utilizado por pacientes con déficit cognitivo. Los resultados del estudio experimental mediante el cual ha sido evaluado demuestran la robustez y usabilidad del sistema, así como su capacidad para intervenir sobre el comportamiento del paciente. El sistema monitorización que ha sido integrado con el entorno virtual aporta datos objetivos sobre el comportamiento del paciente durante la ejecución de la actividad. Los resultados obtenidos permiten contrastar las hipótesis de investigación planteadas en la Tesis Doctoral, aportando soluciones que pueden ayudar a la integración de los entornos virtuales interactivos en la rutina clínica. Esto abre una nueva vía de investigación y desarrollo que podría suponer un gran progreso y mejora en los procesos de neurorrehabilitación cognitiva en daño cerebral. ABSTRACT Brain injury (BI) refers to medical conditions that occur in the brain, altering its function. It becomes one of the main neurological disabilities in the developed society. Cognitive processes determine individual performance in Activities of Daily Living (ADL), thus, the cognitive disorders after BI result in a loss of autonomy and independence, affecting the patient’s quality of life. Cognitive rehabilitation seeks to increase patients’ autonomy and quality of life minimizing or compensating functional disorders showed by BI patients. Brain plasticity is an intrinsic property of the human nervous system whereby its structure is changed depending on experience. Neurorehabilitation pursuits a precise modulation of this intrinsic property, based on specific exercises to induce functional changes, which could result in partial or total recovery of the affected functions. The new methodologies that can be approached by applying technologies to the rehabilitation process, permit to deal with the difficulties which are out of the scope of the traditional rehabilitation. Despite this huge breakthrough, there are still weaknesses in the rehabilitation process, such as the transferring to the real life those skills reached along the therapy, and its generalization to others daily activities. Virtual environments reproduce daily situations. Behavioural requirements which are similar to those we perceive in real life, are simulated in a controlled way. In these virtual environments the therapist is allowed to interact with patients without even being present, inhibiting unsuitable behaviour patterns, stimulating correct answers throughout the simulation and enhancing stimuli with supplementary information when necessary. Despite the benefits which could be brought to the cognitive rehabilitation by applying the potential of the current technologies, there are barriers for widespread use of interactive virtual environments in clinical routine. At present, the evidence that these technologies bring a significant improvement to the cognitive therapies is limited. In other words, there is no evidence about the efficacy of using virtual environments in rehabilitation. In this context, this work aims to address those issues which keep the virtual environments out of the clinical routine. The stages of the cognitive rehabilitation process, which are related with the use and integration of these environments, are analysed: activities design, its implementation in the virtual environment, and the patient’s performance and the data analysis. Hence, the thesis is comprised of the main chapters that are listed below: 1. ADL Design.Definition and configuration of the elements which comprise the ADL allow the therapist to design intervention strategies to influence over the patient behaviour along the activity performance. This chapter aims to formalise the AVD design in order to help neuropsychologists to make use of the interactive virtual environments’ potential but isolating them from the complexity of the technology. With this purpose a new methodology is proposed as an instrument to model the ADL definition, to manage its implied knowledge and to assist the clinician along the design process of the therapeutic intervention. 2. Interactive virtual environment. Continuous advancements make the technology feasible for re-creating rehabilitation therapies based on ADL. The goal of this stage is to analyse the main features of virtual environments in order to apply them according to the cognitive rehabilitation’s requirements. The interactive video is proposed as the technology to develop virtual environments. Experimental study is carried out to assess the suitability of the interactive video to be used by cognitive rehabilitation. 3. ADL monitoring system. This kind of virtual environments bring patients in front lots of stimuli and interactions. Thus, advanced monitoring instruments are needed to provide therapist with objective information about patient’s behaviour. This thesis chapter propose the use of metrics rely on visual patients’ visual attention and their interactions with the environment. A monitoring system has been developed and integrated with the interactive video-based virtual environment, providing neuropsychologist with the instruments to evaluate the clinical force of this metrics. Therapeutic interventions-based ADL has been designed by using the proposed methodology. Interactive video technology has been used to develop the ADL, resulting in a virtual environment prototype to be use by patients who suffer a cognitive deficits. An experimental study has been performed to evaluate the virtual environment, whose overcomes show the usability and solidity of the system, and also its capacity to have influence over patient’s behaviour. The monitoring system, which has been embedded in the virtual environment, provides objective information about patients’ behaviour along their activity performance. Research hypothesis of the Thesis are proven by the obtained results. They could help to incorporate the interactive virtual environments in the clinical routine. This may be a significant step forward to enhance the cognitive neurorehabilitation processes in brain injury.

Facing the climate change challenges in the mining and mineral industry as providers of a sustainable manufacturing process

A sustainable manufacturing process must rely on an also sustainable raw materials and energy supply. This paper is intended to show the results of the studies developed on sustainable business models for the minerals industry as a fundamental previous part of a sustainable manufacturing process. As it has happened in other economic activities, the mining and minerals industry has come under tremendous pressure to improve its social, developmental, and environmental performance. Mining, refining, and the use and disposal of minerals have in some instances led to significant local environmental and social damage. Nowadays, like in other parts of the corporate world, companies are more routinely expected to perform to ever higher standards of behavior, going well beyond achieving the best rate of return for shareholders. They are also increasingly being asked to be more transparent and subject to third-party audit or review, especially in environmental aspects. In terms of environment, there are three inter-related areas where innovation and new business models can make the biggest difference: carbon, water and biodiversity. The focus in these three areas is for two reasons. First, the industrial and energetic minerals industry has significant footprints in each of these areas. Second, these three areas are where the potential environmental impacts go beyond local stakeholders and communities, and can even have global impacts, like in the case of carbon. So prioritizing efforts in these areas will ultimately be a strategic differentiator as the industry businesses continues to grow. Over the next forty years, world?s population is predicted to rise from 6.300 million to 9.500 million people. This will mean a huge demand of natural resources. Indeed, consumption rates are such that current demand for raw materials will probably soon exceed the planet?s capacity. As awareness of the actual situation grows, the public is demanding goods and services that are even more environmentally sustainable. This means that massive efforts are required to reduce the amount of materials we use, including freshwater, minerals and oil, biodiversity, and marine resources. It?s clear that business as usual is no longer possible. Today, companies face not only the economic fallout of the financial crisis; they face the substantial challenge of transitioning to a low-carbon economy that is constrained by dwindling natural resources easily accessible. Innovative business models offer pioneering companies an early start toward the future. They can signal to consumers how to make sustainable choices and provide reward for both the consumer and the shareholder. Climate change and carbon remain major risk discontinuities that we need to better understand and deal with. In the absence of a global carbon solution, the principal objective of any individual country should be to reduce its global carbon emissions by encouraging conservation. The mineral industry internal response is to continue to focus on reducing the energy intensity of our existing operations through energy efficiency and the progressive introduction of new technology. Planning of the new projects must ensure that their energy footprint is minimal from the start. These actions will increase the long term resilience of the business to uncertain energy and carbon markets. This focus, combined with a strong demand for skills in this strategic area for the future requires an appropriate change in initial and continuing training of engineers and technicians and their awareness of the issue of eco-design. It will also need the development of measurement tools for consistent comparisons between companies and the assessments integration of the carbon footprint of mining equipments and services in a comprehensive impact study on the sustainable development of the Economy.
