Understanding social enterprise country models: Spain

Purpose – The purpose of this paper is to describe the historical institutional context of Spain in the past 40 years and to analyze the influence of institutional factors in the current model of social enterprise existing in the country. Design/methodology/approach – This study draws on the theory of historical institutionalism, national-level empirical data and Kerlin conceptual framework (2013) that informs models of social enterprise. Findings – This paper describe some traits of Spain’s social enterprise that can be explained by the evolution of its institutional context in the past 40 years. It helps to validate, from a historical institutionalistic perspective, aspects of the Kerlin framework for social enterprise models. It also begins to show that the analysis of regional differences in the context should be taken into consideration when examining a country’s social enterprise space. Research limitations/implications – This discussion paper encourages academics to analyze regional differences in the emergence of social enterprise within a country. The main limitation of the paper is the lack of an “official” definition of social enterprise in Spain. Originality/value – This paper applies a valuable framework to a country with a unique political and economic history in the past 40 years. It contributes to enrich the research on the emergence and development of social enterprises in a variety of contexts and advances understanding of how regional differences inside a country influence the development of social enterprises.

Video-based tasks for emotional processing rehabilitation in schizophrenia

Schizophrenia is a mental disorder characterized by a breakdown of cognitive processes and by a deficit of typi-cal emotional responses. Effectiveness of computerized task has been demonstrated in the field of cognitive rehabilitation. However, current rehabilitation programs based on virtual environments normally focus on higher cognitive functions, not covering social cognition training. This paper presents a set of video-based tasks specifically designed for the rehabilita-tion of emotional processing deficits in patients in early stages of schizophrenia or schizoaffective disorders. These tasks are part of the Mental Health program of Guttmann NeuroPer-sonalTrainer® cognitive tele-rehabilitation platform, and entail innovation both from a clinical and technological per-spective in relation with former traditional therapeutic con-tents.

Barreras para la práctica de actividad física y deportiva en las personas adultas de la Comunidad de Madrid. Desarrollo y validación de un instrumento

El propósito de este estudio fue la construcción y validación de un instrumento de medición de barreras a la práctica de la actividad física y deportiva por parte de las personas adultas desde la teoría ecológico social y analizar la presencia de las diferentes barreras así como las innovaciones y alternativas de conciliación a las barreras relacionadas con el empleo, el cuidado de hijos e hijas y las tareas del hogar, identificando las posibles diferencias existentes en función del género y del tipo de demanda en la población adulta de la Comunidad de Madrid. Se ha realizado un estudio cuantitativo, descriptivo y transversal en una muestra representativa de la población residente en la Comunidad de Madrid entre 30 y 64 años. El tipo de muestreo fue probabilístico, de tipo polietápico según tamaño demográfico de municipio y género, con un margen de error del ± 5,27% y un intervalo de confianza del 95,5%. El tamaño de la muestra final fue de 360 personas (50,3% mujeres, 49,7% hombres), quienes completaron un cuestionario estructurado mediante entrevista personal cara a cara en su domicilio entre octubre y diciembre de 2011, que incluía una escala de barreras específica, así como sub-cuestionarios de innovaciones y alternativas de conciliación vinculados a los tres ítems relacionados con el empleo, cuidado de hijos e hijas y hogar de la escala de barreras. La escala de barreras fue completada por las personas practicantes de actividad física y deportiva que deseaban realizar otra actividad, es decir, por la Demanda Establecida, así como por las personas no practicantes pero deseosas de hacerlo o Demanda Latente, y las personas no practicantes no interesadas en practicar o Demanda Ausente (n=246). Las personas que alcanzaron elevadas puntuaciones en los tres ítems de la escala de barreras vinculados al empleo, cuidado de hijos e hijas y hogar, completaron sub-cuestionarios específicos de innovaciones y alternativas de conciliación vinculados a estas barreras. Para el estudio métrico de los ítems y la dimesionalidad de la escala de barreras se llevaron a cabo análisis descriptivos de los ítems, análisis correlacionales y análisis factoriales exploratorios (AFE). Como resultado se obtuvo una escala de barreras constituida por 13 ítems que explicaron el 59,1% de la variabilidad total de los datos, agrupados en cuatro dimensiones denominadas: Barreras Interpersonales (2 ítems), Barreras Individuales (4 ítems), Barreras Comunidad-Institucionales (4 ítems) y Barreras Obligaciones-Tiempo (3 ítems). Los datos de la escala de barreras y los sub-cuestionarios de innovaciones y alternativas de conciliación fueron analizados con el SPSS v. 18. Para la comparación de variables cuantitativas y ordinales se utilizaron ANOVAS de dos factores (género por tipo de demanda), el tamaño del efecto para esta prueba se cuantificó mediante eta cuadrado. Los resultados se expresaron como porcentajes para las variables nominales y como medias y desviaciones típicas para las variables ordinales y cuantitativas. El nivel de riesgo se fijó en 0,05. El instrumento presentó una fiabilidad aceptable (α=0,58) en consonancia con el modelo ecológico social presentando dimensiones que explicaron los niveles de influencia de las diferentes esferas. Los resultados obtenidos permitieron avalar tanto la adecuación de las propiedades psicométricas de los ítems, así como la validez y fiabilidad de la escala de barreras para la práctica de actividad física y deportiva. Los distintos análisis realizados han aportado evidencia de la validez de una estructura de cuatro dimensiones acorde a los planteamientos teóricos previos de los modelos ecológicos sociales. En la dimensión barreras Individuales se identificaron diferencias según el tipo de demanda (F2,237=40,28; p<0,001; η2=0,25) y el género (F1,237=8,72; p<0,01; η2=0,84). En la dimensión barreras Interpersonales se identificaron diferencias de género (F1,239 =14,9; p<0,01; η2=0,06) pero no entre demandas (F2,239=2,35; p>0,05; 1-β=0,47). En la dimensión Barreras Obligaciones-Tiempo se identificaron diferencias en función del tipo de demanda (F2,239=3,88; p<0,05; η2=0,03) sin presentar diferencias entre hombres y mujeres (F1,239=1,06; p>0,05; 1-β=0,18). Por último, en la dimensión Comunidad Institucionales, se identificaron diferencias en función del tipo de demanda (F2,240=5,69; p<0,01; η2=0,045) y no hubo diferencias en función del género (F1,240=0,65; p>0,05; 1-β=0,13). Las innovaciones y alternativas de conciliación relacionadas con el empleo más valoradas fueron la de flexibilidad en los horarios de trabajo y adecuación de horarios; las más valoradas relacionadas con la barrera cuidado de hijos fueron que en la instalación deportiva se ofertaran actividades físicas conjuntas, en las en las que pudiesen participar madres e hijos y que la instalación deportiva ofreciera, en el mismo horario, actividades para ellos y sus hijos, y, por último, las más valoradas en relación con las tareas del hogar, una mayor implicación de la pareja seguida por una mayor implicación de los hijos. ABSTRACT The objectives of this study were to build and validate an instrument to measure the barriers of adult people to the practice of sport and physical activities from the perspective of the social-ecological theory, analyse the presence of the different barriers, as well as the innovations and alternatives regarding conciliation with work and the care of children and home as barriers, identifying the possible differences that exist based on gender and the type of demand of the adult population within the Community of Madrid. For this, a quantitative, descriptive and transversal study was carried out on a representative sample of the resident population of the Community of Madrid, ages ranging from 30 to 64 years old. Given that is an infinite or very large population, and working with an interval of confidence of the 95,5%, and assuming in the population variance, the worst case of p equal to q, the margin of sampling error was ± 5,27. The sample consisted of 360 people (50,3% women, 49,7% men), who completed a questionnaire during face-to-face personal interviews between October and December 2011. The questionnaire included a scale of specific barriers, as well as sub-questionnaires on the innovations and alternatives linked to the three items regarding work, the care of children and home of the barriers scale. The barriers scale was completed by people who practice physical and sport activities and wanted to do other activities, i.e. by the Established Demand; by people who do not practice these activities but would like to do so, i.e. Latent Demand; and by people who do not practice these activities and have no desire to do so, i.e. Absent Demand (n=246). The people who peaked on the three items of the barriers scale regarding work, the care of children and home, then completed specific sub-questionnaires on the innovations and alternatives for conciliation related to these barriers. The metric study of the items and the dimensionality of the barriers scale was carried out through descriptive analyses of the items, as well as correlation analyses and exploratory factor analyses (EFA). This resulted in a barriers scale composed of 13 items that explained 59,1% of the total variability of the data, grouped in four dimensions as follows: Interpersonal Barriers (2 items), Individual Barriers (4 items), Community-Institutional Barriers (4 items) and Obligations-Time Barriers (3 items). The data obtained from the barriers scale and sub-questionnaires on the innovations and alternatives for conciliation were analyzed using software SPSS v. 18. Two-way ANOVA (gender by type of demand) was used for the comparison of quantitative and ordinal variables, and the effect size for this test was quantified with eta squared. The results were expressed as percentages for nominal variables, and as means and standard deviations for quantitative and ordinal variables. The level of risk was set at 0,05. The instrument showed an acceptable reliability (α=0,58) in line with the social-ecological model, providing dimensions that explained the influence levels of the different spheres. The results obtained establish both the adaptation of the psychometric properties of the items, and the validity and reliability of the barriers scale for the practice of physical and sport activities. The different analyses have supported the validity of a four-dimensional structure consistent with the previous theoretical approaches on the social-ecological models, while showing adequate statistical indices. The differences identified in the Individual Barriers dimension were based on the type of demand (F2,237=40,28; p<0,001; η2=0,25) and gender (F1,237=8,72; p<0,01; η2=0,84). The differences identified in the Interpersonal Barriers dimension were based on gender (F1,239 =14,9; p<0,01; η2=0,06) but not on demand (F2,239=2,35; p>0,05; 1-β=0,47). The differences identified for the Obligations-Time Barriers dimension were based on the type of demand (F2,239=3,88; p<0,05; η2=0,03) and did not show differences between men and women (F1,239=1,06; p>0,05; 1-β=0,18). Finally, the differences identified for the Community-Institutional Barriers dimension were based on the type of demand (F2,240=5,69; p<0,01; η2=0,045) and provided no differences based on gender (F1,240=0,65; p>,05; 1-β=0,13). The most valued innovations and alternatives for conciliation regarding work were the adaptation and flexibility of working hours and timetables; the most valued related to the care of children were the offer of joint activities for adults and children in sport centres, as well as separate activities within the same timetable; and, finally, the most valued regarding the home was a higher degree of participation and involvement on the part of the spouse or partner, followed by a higher degree of participation and involvement on the part of the children.

Characterization of ICT-based business models of social enterprises

In recent years new models for organizations working on overty alleviation have emerged. One of them, the social enterprise, has attracted the attention of both academics and practitioners all over the world. Even if defined in different ways depending on the context, social enterprise has an enormous potential to generate social benefits and to promote local agency and private initiative in poverty alleviation. In this sense, it is fitting to highlight the importance of identifying the main standards that permit the characterization of diverse social enterprises, in order to understand their main specificities and guarantee value generation for low-income populations. Another crucial factor is understanding innovation as a critical factor in promoting social enterprises. A powerful tool to enhance the impact and application of this model is Information and Communication Technologies. In the 21st century,these tools allow users to find new ways of collaboration, new sustainable business models and a cost-effective way of scaling-up initiatives. This paper, a product of the collaborative research between the Universidad Politécnica de Madrid and the Universidade Federal Fluminense, examines different business models for social enterprises and the role that ICT can play in scale and impact of these initiatives

La Empresa Social: Revisión de Conceptos y Modelo para el Análisis Organizativo

In recent years, interest has been drawn towards new inclusive business models designed to generate opportunities for human development and thus improve the living standards of the poorest. Social enterprise, defined as an organization that aims to create social value by developing an economic activity, can influence change and therefore serve as a model to create sustainable organizations in the coming years. This paper will describe the concept of social enterprise from two different points of view ? that of the traditional European social economy and the developing economies approach. In addition, it will propose a model for the organizational analysis and will apply the suggested model in the case of Grameen-Danone.

Social attitude toward sustainable development in 2025: A case for reinforcing scenario design

This paper shows the role that some foresight tools, such as scenario design, may play in exploring the future impacts of global challenges in our contemporary Society. Additionally, it provides some clues about how to reinforce scenario design so that it displays more in-depth analysis without losing its qualitative nature and communication advantages. Since its inception in the early seventies, scenario design has become one of the most popular foresight tools used in several fields of knowledge. Nevertheless, its wide acceptance has not been seconded by the urban planning academic and professional realm. In some instances, scenario design is just perceived as a story telling technique that generates oversimplified future visions without the support of rigorous and sound analysis. As a matter of fact, the potential of scenario design for providing more in-depth analysis and for connecting with quantitative methods has been generally missed, giving arguments away to its critics. Based on these premises, this document tries to prove the capability of scenario design to anticipate the impacts of complex global challenges and to do it in a more analytical way. These assumptions are tested through a scenario design exercise which explores the future evolution of the sustainable development paradigm (SD) and its implications in the Spanish urban development model. In order to reinforce the perception of scenario design as a useful and added value instrument to urban planners, three sets of implications –functional, parametric and spatial— are displayed to provide substantial and in-depth information for policy makers. This study shows some major findings. First, it is feasible to set up a systematic approach that provides anticipatory intelligence about future disruptive events that may affect the natural environment and socioeconomic fabric of a given territory. Second, there are opportunities for innovating in the Spanish urban planning processes and city governance models. Third, as a foresight tool, scenario design can be substantially reinforced if proper efforts are made to display functional, parametric and spatial implications generated by the scenarios. Fourth, the study confirms that foresight offers interesting opportunities for urban planners, such as anticipating changes, formulating visions, fostering participation and building networks

Mathematical models for the arrangement and the cleaning of the river basin and surroundings of the river sandy grounds to its passage by the city of Salta (Argentina)

The province of Salta is located the Northwest of Argentina in the border with Bolivia, Chile and Paraguay. Its Capital is the city of Salta that concentrates half of the inhabitants of the province and has grown to 600000 hab., from a small active Spanish town well founded in 1583. The city is crossed by the Arenales River descending from close mountains at North, source of water and end of sewers. But with actual growing it has become a focus of infection and of remarkable unhealthiness. It is necessary to undertake a plan for the recovery of the river, directed to the attainment of the well-being and to improve the life?s quality of the Community. The fundamental idea of the plan is to obtain an ordering of the river basin and an integral management of the channel and its surroundings, including the cleaning out. The improvement of the water?s quality, the healthiness of the surroundings and the improvement of the environment, must go hand by hand with the development of sport activities, of relaxation, tourism, establishment of breeding grounds, kitchen gardens, micro enterprises with clean production and other actions that contribute to their benefit by the society, that being a basic factor for their care and sustainable use. The present pollution is organic, chemical, industrial, domestic, due to the disposition of sweepings and sewer effluents that affects not only the flora and small fauna, destroying the biodiversity, but also to the health of people living in their margins. Within the plan it will be necessary to consider, besides hydric and environmental cleaning and the prevention of floods, the planning of the extraction of aggregates, the infrastructure and consolidation of margins works and the arrangement of all the river basin. It will be necessary to consider the public intervention at state, provincial and local level, and the private intervention. In the model it has been necessary to include the sub-model corresponding to the election of the entity to be the optimal instrument to reach the proposed objectives, giving an answer to the social, environmental and economic requirements. For that the authors have used multi-criteria decision methods to qualify and select alternatives, and for the programming of their implementation. In the model the authors have contemplated the short, average and long term actions. They conform a Paretooptimal alternative which secures the ordering, integral and suitable management of the basin of the Arenales River, focusing on its passage by the city of Salta.

Some past decision theory models for euro construction model codes and for road drainage in Spain, and modest hints with multi-criteria methods for agro and environmental assurance

The authors are from UPM and are relatively grouped, and all have intervened in different academic or real cases on the subject, at different times as being of different age. With precedent from E. Torroja and A. Páez in Madrid Spain Safety Probabilistic models for concrete about 1957, now in ICOSSAR conferences, author J.M. Antón involved since autumn 1967 for euro-steel construction in CECM produced a math model for independent load superposition reductions, and using it a load coefficient pattern for codes in Rome Feb. 1969, practically adopted for European constructions, giving in JCSS Lisbon Feb. 1974 suggestion of union for concrete-steel-al.. That model uses model for loads like Gumbel type I, for 50 years for one type of load, reduced to 1 year to be added to other independent loads, the sum set in Gumbel theories to 50 years return period, there are parallel models. A complete reliability system was produced, including non linear effects as from buckling, phenomena considered somehow in actual Construction Eurocodes produced from Model Codes. The system was considered by author in CEB in presence of Hydraulic effects from rivers, floods, sea, in reference with actual practice. When redacting a Road Drainage Norm in MOPU Spain an optimization model was realized by authors giving a way to determine the figure of Return Period, 10 to 50 years, for the cases of hydraulic flows to be considered in road drainage. Satisfactory examples were a stream in SE of Spain with Gumbel Type I model and a paper of Ven Te Chow with Mississippi in Keokuk using Gumbel type II, and the model can be modernized with more varied extreme laws. In fact in the MOPU drainage norm the redacting commission acted also as expert to set a table of return periods for elements of road drainage, in fact as a multi-criteria complex decision system. These precedent ideas were used e.g. in wide Codes, indicated in symposia or meetings, but not published in journals in English, and a condensate of contributions of authors is presented. The authors are somehow involved in optimization for hydraulic and agro planning, and give modest hints of intended applications in presence of agro and environment planning as a selection of the criteria and utility functions involved in bayesian, multi-criteria or mixed decision systems. Modest consideration is made of changing in climate, and on the production and commercial systems, and on others as social and financial.

Definición de un nuevo modelo de negocio sostenible y aplicable a la nueva realidad de negocios y social para la convergencia de operadores de telecomunicación e Internet

La presente tesis analiza la integración del sector de las telecomunicaciones con los de TI y medios que conforman el actual hiper-sector de las TIC, para abordar una propuesta de valor que se plantea a dos niveles. Se expone de un lado, la iniciativa WIMS 2.0, que aborda los aspectos tecnológicos y estratégicos de la convergencia telco e Internet para, posteriormente, definir un nuevo modelo de negocio, que adaptado al nuevo sector integrado y siguiendo paradigmas inéditos como los que plantea la innovación abierta, permita generar nuevos flujos de ingresos en áreas no habituales para los operadores de telecomunicaciones. A lo largo del capítulo 2, el lector encontrará la contextualización del entorno de las comunicaciones de banda ancha desde tres vertientes: los aspectos tecnológicos, los económicos y el mercado actual, todo ello enfocado en una dimensión nacional, europea y mundial. Se establece de esta manera las bases para el desarrollo de los siguientes capítulos al demostrar cómo la penetración de la banda ancha ha potenciado el desarrollo de un nuevo sistema de valor en el sector integrado de las TIC, alrededor del cual surgen propuestas de modelos de negocio originales que se catalogan en una taxonomía propia. En el tercer capítulo se detalla la propuesta de valor de la iniciativa WIMS 2.0, fundada y liderada por el autor de esta tesis. WIMS 2.0, como iniciativa abierta, se dirige a la comunidad como una propuesta de un nuevo ecosistema y como un modelo de referencia integrado sobre el que desplegar servicios convergentes. Adicionalmente, sobre el planteamiento teórico definido se aporta el enfoque práctico que supone el despliegue del modelo de referencia dentro de la arquitectura de un operador como Telefónica. El capítulo 4 muestra el modelo de negocio Innovación 2.0, basado en la innovación abierta con el objetivo de capturar nuevos flujos de ingresos incrementando el portfolio de servicios innovadores gracias a las ideas frescas y brillantes de start-ups. Innovación 2.0 lejos de quedarse en una mera propuesta teórica, muestra sus bondades en el éxito práctico en el mercado que ha validado las hipótesis planteadas. El último capítulo plantea las líneas futuras de investigación tanto en el ámbito de la iniciativa WIMS 2.0 como en el modelo de Innovación 2.0, algunas de las cuales se están comenzando a abordar. 3 Abstract This thesis examines the integration of telecommunications sector with IT and media that make up the current hyper-ICT sector, to address a value proposition that arises at two levels. On one side, WIMS 2.0 initiative, which addresses the technological and strategic aspects of the telco and Internet convergence to later define a new business model, adapted to the new integrated sector and following original paradigms such as those posed by open innovation, which generates new revenue streams in areas not typical for telecom operators. Throughout Chapter 2, the reader will find the contextualization of the broadband communications environment from three aspects: technological, economic and the current market all focused on a national, European and world scale. Thus it establishes the basis for the development of the following chapters by demonstrating how the penetration of broadband has led to the development of a new value system in the integrated sector of the ICT, around which arise proposals of originals business models, which are categorized in a own taxonomy. The third chapter outlines the value proposition of the WIMS 2.0 initiative, founded and led by the author of this thesis. WIMS 2.0, as open initiative, presents to the community a proposal for a new ecosystem and an integrated reference model on which to deploy converged services. Additionally, above the theoretical approach defined, WIMS 2.0 provides the practical approach is provided which is the deployment of the reference model into the architecture of an operator such as Telefónica. Chapter 4 shows the Innovation 2.0 business model, based on open innovation with the goal of capturing new revenue streams by increasing the portfolio of innovative services thanks to the fresh and brilliant ideas from start-ups. Innovation 2.0, far from being a mere theoretical proposition, shows its benefits in the successful deployment in the market, which has validated the hypotheses. The last chapter sets out the future research at both the WIMS 2.0 initiative and Innovation 2.0 model, some of which are beginning to be addressed.

La telefonía móvil : el impacto social

El objetivo de este proyecto ha sido el de realizar un análisis del importante desarrollo que han sufrido las telecomunicaciones, haciendo un especial hincapié en la telefonía móvil y el impacto y repercusión que ha causado actualmente en nuestra sociedad. Para ello se hará un repaso evolutivo de las tecnologías de la información y las telecomunicaciones, y se establecerá una relación entre la gran difusión de éstas y su efecto sobre los usos, y cambios percibidos por los consumidores del nuevo siglo. Ciertamente la historia de la tecnología, nos enseña que la gente y las organizaciones acaban utilizándola para unos propósitos muy diferentes de aquellos que inicialmente fueron concebidas. Además cuanto más interactiva sea una tecnología, tanto más probable será que los usuarios se conviertan en productores o modificadores de la misma. Por tanto, la sociedad necesita resolver las incógnitas que pueda suscitar el rápido y continúo cambio de las comunicaciones. Este proyecto trata de ayudar a responder alguna de las cuestiones que actualmente se están planteando. ¿Son los teléfonos móviles una expresión de identidad, artilugios de moda, herramientas de la vida cotidiana, o todo lo anterior? ¿Existen nuevos modelos de comportamiento y conducta social? ¿La comunicación móvil está favoreciendo la aparición de una nueva cultura joven con un lenguaje propio basado en la comunicación textual y multimodal? ¿Tienen los teléfonos móviles efectos nocivos en la salud? La respuesta a estas preguntas afecta a nuestras vidas y también condiciona las políticas públicas y las estrategias de negocio, por eso requiere adquirir un conocimiento cimentado en la información, y la recopilación de datos de diversas fuentes, tanto de estadísticas provenientes de diferentes estudios e investigaciones, como de empresas consultoras, siempre basada en una perspectiva global. En conjunto, se espera dentro de los límites del conocimiento actual, contribuir a establecer las bases para el análisis y valoración de la relación existente entre comunicación, tecnología y sociedad en todo el mundo. Abstract The purpose of this project has been to analyse the significant development undergone by telecommunications, putting a special emphasis on mobile phones and the impact it has caused in society. We will go over the evolution of IT technologies and telecommunications as well as establish a relationship between its spread and effect of its uses and changes understood by the new century consumers. Technology history shows us that people and organizations use it for very different purposes from those originally thought. Furthermore, the more interactive technologies are, the more users will modify or produce it. Therefore, society needs to solve the mysteries of the quick and continuous change of communications. This project tries to help and answer some of the questions considered these days. Are mobile phones an expression of identity, fashionable devices, tools for everyday life or all at once? Are there any new models of performance and social behaviour? Is mobile communication favouring the existence of a new young culture with a typical language based on textual and multimodal communication? Are mobile phones bad for our health? The answer to these questions affects us all and conditions public politics and business strategies so it is required to get firm knowledge based on information. It is also important to compile data from various sources, from statistics of research and studies, based on a global perspective. As a whole, we hope to contribute to establish the bases for the future analysis and assessment of a fundamental trend that is redefining the relationship between communication, technology and society worldwide by transforming the wireless networks that make our lives.

Response threshold models, stochastic learning automata and ant colony optimization-based decentralized self-coordination algorithms for heterogeneous multi-tasks distribution in multi-robot systems

In recent decades, there has been an increasing interest in systems comprised of several autonomous mobile robots, and as a result, there has been a substantial amount of development in the eld of Articial Intelligence, especially in Robotics. There are several studies in the literature by some researchers from the scientic community that focus on the creation of intelligent machines and devices capable to imitate the functions and movements of living beings. Multi-Robot Systems (MRS) can often deal with tasks that are dicult, if not impossible, to be accomplished by a single robot. In the context of MRS, one of the main challenges is the need to control, coordinate and synchronize the operation of multiple robots to perform a specic task. This requires the development of new strategies and methods which allow us to obtain the desired system behavior in a formal and concise way. This PhD thesis aims to study the coordination of multi-robot systems, in particular, addresses the problem of the distribution of heterogeneous multi-tasks. The main interest in these systems is to understand how from simple rules inspired by the division of labor in social insects, a group of robots can perform tasks in an organized and coordinated way. We are mainly interested on truly distributed or decentralized solutions in which the robots themselves, autonomously and in an individual manner, select a particular task so that all tasks are optimally distributed. In general, to perform the multi-tasks distribution among a team of robots, they have to synchronize their actions and exchange information. Under this approach we can speak of multi-tasks selection instead of multi-tasks assignment, which means, that the agents or robots select the tasks instead of being assigned a task by a central controller. The key element in these algorithms is the estimation ix of the stimuli and the adaptive update of the thresholds. This means that each robot performs this estimate locally depending on the load or the number of pending tasks to be performed. In addition, it is very interesting the evaluation of the results in function in each approach, comparing the results obtained by the introducing noise in the number of pending loads, with the purpose of simulate the robot's error in estimating the real number of pending tasks. The main contribution of this thesis can be found in the approach based on self-organization and division of labor in social insects. An experimental scenario for the coordination problem among multiple robots, the robustness of the approaches and the generation of dynamic tasks have been presented and discussed. The particular issues studied are: Threshold models: It presents the experiments conducted to test the response threshold model with the objective to analyze the system performance index, for the problem of the distribution of heterogeneous multitasks in multi-robot systems; also has been introduced additive noise in the number of pending loads and has been generated dynamic tasks over time. Learning automata methods: It describes the experiments to test the learning automata-based probabilistic algorithms. The approach was tested to evaluate the system performance index with additive noise and with dynamic tasks generation for the same problem of the distribution of heterogeneous multi-tasks in multi-robot systems. Ant colony optimization: The goal of the experiments presented is to test the ant colony optimization-based deterministic algorithms, to achieve the distribution of heterogeneous multi-tasks in multi-robot systems. In the experiments performed, the system performance index is evaluated by introducing additive noise and dynamic tasks generation over time.

Improving the analysis of road pricing acceptability surveys by using hybrid models

Several international studies have analyzed the acceptability of road pricing schemes by means of an attitude survey in combination with the results of a stated choice experiment using both a descriptive analysis and a discrete-choice model with binary choice (?accept? or ?not accept? the toll). However, the use of hybrid discrete choice models constitutes an innovative alternative for integrating subjective attitudes and perceptions deriving from the survey of attitudes with the more objective variables from the stated choice experiment. This paper analyzes the results of applying these models to measure the acceptability of interurban road pricing among different groups of stakeholders (road freight and passenger operators, highway concessionaires, and associations of private car users) with qualitatively significant opinions on road pricing measures. Our results show that hybrid models are better suited to explaining the acceptability of a road pricing scheme by different groups of stakeholders than a separate analysis of the survey of attitudes and a discrete-choice model applied on a stated choice experiment. A particular finding was that the strong psycho-social latent variable of the perception of fairness explains the rejection or acceptance of a toll scheme by road stakeholders.

Development of mathematical models to elaborate strategies, select alternatives and development of plans for adaptation of communities to climate change in different geographical areas including costs to implement it.

There is evidence that the climate changes and that now, the change is influenced and accelerated by the CO2 augmentation in atmosphere due to combustion by humans. Such ?Climate change? is on the policy agenda at the global level, with the aim of understanding and reducing its causes and to mitigate its consequences. In most countries and international organisms UNO (e.g. Rio de Janeiro 1992), OECD, EC, etc . . . the efforts and debates have been directed to know the possible causes, to predict the future evolution of some variable conditioners, and trying to make studies to fight against the effects or to delay the negative evolution of such. The Protocol of Kyoto 1997 set international efforts about CO2 emissions, but it was partial and not followed e.g. by USA and China . . . , and in Durban 2011 the ineffectiveness of humanity on such global real challenges was set as evident. Among all that, the elaboration of a global model was not boarded that can help to choose the best alternative between the feasible ones, to elaborate the strategies and to evaluate the costs, and the authors propose to enter in that frame for study. As in all natural, technological and social changes, the best-prepared countries will have the best bear and the more rapid recover. In all the geographic areas the alternative will not be the same one, but the model must help us to make the appropriated decision. It is essential to know those areas that are more sensitive to the negative effects of climate change, the parameters to take into account for its evaluation, and comprehensive plans to deal with it. The objective of this paper is to elaborate a mathematical model support of decisions, which will allow to develop and to evaluate alternatives of adaptation to the climatic change of different communities in Europe and Latin-America, mainly in especially vulnerable areas to the climatic change, considering in them all the intervening factors. The models will consider criteria of physical type (meteorological, edaphic, water resources), of use of the ground (agriculturist, forest, mining, industrial, urban, tourist, cattle dealer), economic (income, costs, benefits, infrastructures), social (population), politician (implementation, legislation), educative (Educational programs, diffusion) and environmental, at the present moment and the future. The intention is to obtain tools for aiding to get a realistic position for these challenges, which are an important part of the future problems of humanity in next decades.

Development of mathematical models to elaborate strategies, to select alternatives and the development of plans for the adaptation of communities to climate change in different geographical areas including costs to implement it

Climate change is on the policy agenda at the global level, with the aim of understanding and reducing its causes and to mitigate its consequences. In most of the countries and international organisms UNO, OECD, EC, etc … the efforts and debates have been directed to know the possible causes, to predict the future evolution of some variable conditioners, and trying to make studies to fight against the effects or to delay the negative evolution of such. Nevertheless, the elaboration of a global model was not boarded that can help to choose the best alternative between the feasible ones, to elaborate the strategies and to evaluate the costs. As in all natural, technological and social changes, the best-prepared countries will have the best bear and the more rapid recover. In all the geographic areas the alternative will not be the same one, but the model should help us to make the appropriated decision. It is essential to know those areas that are more sensitive to the negative effects of climate change, the parameters to take into account for its evaluation, and comprehensive plans to deal with it. The objective of this paper is to elaborate a mathematical model support of decisions, that will allow to develop and to evaluate alternatives of adaptation to the climatic change of different communities in Europe and Latin-America, mainly, in vulnerable areas to the climatic change, considering in them all the intervening factors. The models will take into consideration criteria of physical type (meteorological, edaphic, water resources), of use of the ground (agriculturist, forest, mining, industrial, urban, tourist, cattle dealer), economic (income, costs, benefits, infrastructures), social (population), politician (implementation, legislation), educative (Educational programs, diffusion), sanitary and environmental, at the present moment and the future.

A methodology for the implementation and continuous improvement of social responsibility (RS) and financial responsibility

This work sets out an innovative methodology that aims to facilitate the implementation and continuous improvement of Social Responsibility. It is a methodology that takes account of strategic-economic, social and environmental questions and allows measuring the impact of each of these aspects on the stakeholders and on each of the value areas. It can be extrapolated to all kinds of organisations regardless of their size and sector and admits scaleable models. A marked feature that sets it aside from other methodologies is that it eliminates subjectivity from the qualitative aspects and introduces an algorithm to quantify them.
