Exploring the link between sustainability reporting and sustainability management: a conceptual framework.

Sustainability managementand Sustainability Reporting (SR) practices have dramatically increased during the last two decades, raising important questions about the relationship between internal practices and external communication. Previous literature on SR has almost exclusively highlighted the role of institutional and stakeholder pressures in driving its adoption. However, as surveys among reporters also identify internal benefits of SR, its full role for company-level sustainability management remains unclear. In order to address this question, we develop a framework accounting for four SR configurations, stemming from different levels of relative importance of external and internal motives for SR. A multiple case study involving four large Spanish companies serves to illustrate the framework and to identify company-level factors that act both as enablers and barriers of SR internal relevance. We conclude that motivations for SR, along with such internal factors, decisively influence its contribution to sustainability management.

Emergency management in the highways of the future. A performance-based multilayered ITS architecture design proposal

Emergency management is one of the key aspects within the day-to-day operation procedures in a highway. Efficiency in the overall response in case of an incident is paramount in reducing the consequences of any incident. However, the approach of highway operators to the issue of incident management is still usually far from a systematic, standardized way. This paper attempts to address the issue and provide several hints on why this happens, and a proposal on how the situation could be overcome. An introduction to a performance based approach to a general system specification will be described, and then applied to a particular road emergency management task. A real testbed has been implemented to show the validity of the proposed approach. Ad-hoc sensors (one camera and one laser scanner) were efficiently deployed to acquire data, and advanced fusion techniques applied at the processing stage to reach the specific user requirements in terms of functionality, flexibility and accuracy.

Strengthening and measuring project management competences of engineering students

Since 2010 the Industrial Engineering School at Universidad Politécnica de Madrid (ETSII UPM) has its Plan Study accredited by ABET. Since then a big motivation has been promoted from the management team encouraging teachers to work on the measurement and strengthening of student¿s competences. Generic skills or behavior acquired significant importance in the workplace, particularly in relation to project management. Because of this, and framed within the requirements of the European Higher Education Area (EHEA), the curriculum of the new degrees are being developed under the competence-based learning. This situation leads to the need to have a clear measurement tool skills as a basis for developing them within the curriculum. A group of multidisciplinary teachers have been working together during two years to design measuring instruments valid for engineering students.

Contributions to the Resilience Management in the Internet of Things

El auge del "Internet de las Cosas" (IoT, "Internet of Things") y sus tecnologías asociadas han permitido su aplicación en diversos dominios de la aplicación, entre los que se encuentran la monitorización de ecosistemas forestales, la gestión de catástrofes y emergencias, la domótica, la automatización industrial, los servicios para ciudades inteligentes, la eficiencia energética de edificios, la detección de intrusos, la gestión de desastres y emergencias o la monitorización de señales corporales, entre muchas otras. La desventaja de una red IoT es que una vez desplegada, ésta queda desatendida, es decir queda sujeta, entre otras cosas, a condiciones climáticas cambiantes y expuestas a catástrofes naturales, fallos de software o hardware, o ataques maliciosos de terceros, por lo que se puede considerar que dichas redes son propensas a fallos. El principal requisito de los nodos constituyentes de una red IoT es que estos deben ser capaces de seguir funcionando a pesar de sufrir errores en el propio sistema. La capacidad de la red para recuperarse ante fallos internos y externos inesperados es lo que se conoce actualmente como "Resiliencia" de la red. Por tanto, a la hora de diseñar y desplegar aplicaciones o servicios para IoT, se espera que la red sea tolerante a fallos, que sea auto-configurable, auto-adaptable, auto-optimizable con respecto a nuevas condiciones que puedan aparecer durante su ejecución. Esto lleva al análisis de un problema fundamental en el estudio de las redes IoT, el problema de la "Conectividad". Se dice que una red está conectada si todo par de nodos en la red son capaces de encontrar al menos un camino de comunicación entre ambos. Sin embargo, la red puede desconectarse debido a varias razones, como que se agote la batería, que un nodo sea destruido, etc. Por tanto, se hace necesario gestionar la resiliencia de la red con el objeto de mantener la conectividad entre sus nodos, de tal manera que cada nodo IoT sea capaz de proveer servicios continuos, a otros nodos, a otras redes o, a otros servicios y aplicaciones. En este contexto, el objetivo principal de esta tesis doctoral se centra en el estudio del problema de conectividad IoT, más concretamente en el desarrollo de modelos para el análisis y gestión de la Resiliencia, llevado a la práctica a través de las redes WSN, con el fin de mejorar la capacidad la tolerancia a fallos de los nodos que componen la red. Este reto se aborda teniendo en cuenta dos enfoques distintos, por una parte, a diferencia de otro tipo de redes de dispositivos convencionales, los nodos en una red IoT son propensos a perder la conexión, debido a que se despliegan en entornos aislados, o en entornos con condiciones extremas; por otra parte, los nodos suelen ser recursos con bajas capacidades en términos de procesamiento, almacenamiento y batería, entre otros, por lo que requiere que el diseño de la gestión de su resiliencia sea ligero, distribuido y energéticamente eficiente. En este sentido, esta tesis desarrolla técnicas auto-adaptativas que permiten a una red IoT, desde la perspectiva del control de su topología, ser resiliente ante fallos en sus nodos. Para ello, se utilizan técnicas basadas en lógica difusa y técnicas de control proporcional, integral y derivativa (PID - "proportional-integral-derivative"), con el objeto de mejorar la conectividad de la red, teniendo en cuenta que el consumo de energía debe preservarse tanto como sea posible. De igual manera, se ha tenido en cuenta que el algoritmo de control debe ser distribuido debido a que, en general, los enfoques centralizados no suelen ser factibles a despliegues a gran escala. El presente trabajo de tesis implica varios retos que conciernen a la conectividad de red, entre los que se incluyen: la creación y el análisis de modelos matemáticos que describan la red, una propuesta de sistema de control auto-adaptativo en respuesta a fallos en los nodos, la optimización de los parámetros del sistema de control, la validación mediante una implementación siguiendo un enfoque de ingeniería del software y finalmente la evaluación en una aplicación real. Atendiendo a los retos anteriormente mencionados, el presente trabajo justifica, mediante una análisis matemático, la relación existente entre el "grado de un nodo" (definido como el número de nodos en la vecindad del nodo en cuestión) y la conectividad de la red, y prueba la eficacia de varios tipos de controladores que permiten ajustar la potencia de trasmisión de los nodos de red en respuesta a eventuales fallos, teniendo en cuenta el consumo de energía como parte de los objetivos de control. Así mismo, este trabajo realiza una evaluación y comparación con otros algoritmos representativos; en donde se demuestra que el enfoque desarrollado es más tolerante a fallos aleatorios en los nodos de la red, así como en su eficiencia energética. Adicionalmente, el uso de algoritmos bioinspirados ha permitido la optimización de los parámetros de control de redes dinámicas de gran tamaño. Con respecto a la implementación en un sistema real, se han integrado las propuestas de esta tesis en un modelo de programación OSGi ("Open Services Gateway Initiative") con el objeto de crear un middleware auto-adaptativo que mejore la gestión de la resiliencia, especialmente la reconfiguración en tiempo de ejecución de componentes software cuando se ha producido un fallo. Como conclusión, los resultados de esta tesis doctoral contribuyen a la investigación teórica y, a la aplicación práctica del control resiliente de la topología en redes distribuidas de gran tamaño. Los diseños y algoritmos presentados pueden ser vistos como una prueba novedosa de algunas técnicas para la próxima era de IoT. A continuación, se enuncian de forma resumida las principales contribuciones de esta tesis: (1) Se han analizado matemáticamente propiedades relacionadas con la conectividad de la red. Se estudia, por ejemplo, cómo varía la probabilidad de conexión de la red al modificar el alcance de comunicación de los nodos, así como cuál es el mínimo número de nodos que hay que añadir al sistema desconectado para su re-conexión. (2) Se han propuesto sistemas de control basados en lógica difusa para alcanzar el grado de los nodos deseado, manteniendo la conectividad completa de la red. Se han evaluado diferentes tipos de controladores basados en lógica difusa mediante simulaciones, y los resultados se han comparado con otros algoritmos representativos. (3) Se ha investigado más a fondo, dando un enfoque más simple y aplicable, el sistema de control de doble bucle, y sus parámetros de control se han optimizado empleando algoritmos heurísticos como el método de la entropía cruzada (CE, "Cross Entropy"), la optimización por enjambre de partículas (PSO, "Particle Swarm Optimization"), y la evolución diferencial (DE, "Differential Evolution"). (4) Se han evaluado mediante simulación, la mayoría de los diseños aquí presentados; además, parte de los trabajos se han implementado y validado en una aplicación real combinando técnicas de software auto-adaptativo, como por ejemplo las de una arquitectura orientada a servicios (SOA, "Service-Oriented Architecture"). ABSTRACT The advent of the Internet of Things (IoT) enables a tremendous number of applications, such as forest monitoring, disaster management, home automation, factory automation, smart city, etc. However, various kinds of unexpected disturbances may cause node failure in the IoT, for example battery depletion, software/hardware malfunction issues and malicious attacks. So, it can be considered that the IoT is prone to failure. The ability of the network to recover from unexpected internal and external failures is known as "resilience" of the network. Resilience usually serves as an important non-functional requirement when designing IoT, which can further be broken down into "self-*" properties, such as self-adaptive, self-healing, self-configuring, self-optimization, etc. One of the consequences that node failure brings to the IoT is that some nodes may be disconnected from others, such that they are not capable of providing continuous services for other nodes, networks, and applications. In this sense, the main objective of this dissertation focuses on the IoT connectivity problem. A network is regarded as connected if any pair of different nodes can communicate with each other either directly or via a limited number of intermediate nodes. More specifically, this thesis focuses on the development of models for analysis and management of resilience, implemented through the Wireless Sensor Networks (WSNs), which is a challenging task. On the one hand, unlike other conventional network devices, nodes in the IoT are more likely to be disconnected from each other due to their deployment in a hostile or isolated environment. On the other hand, nodes are resource-constrained in terms of limited processing capability, storage and battery capacity, which requires that the design of the resilience management for IoT has to be lightweight, distributed and energy-efficient. In this context, the thesis presents self-adaptive techniques for IoT, with the aim of making the IoT resilient against node failures from the network topology control point of view. The fuzzy-logic and proportional-integral-derivative (PID) control techniques are leveraged to improve the network connectivity of the IoT in response to node failures, meanwhile taking into consideration that energy consumption must be preserved as much as possible. The control algorithm itself is designed to be distributed, because the centralized approaches are usually not feasible in large scale IoT deployments. The thesis involves various aspects concerning network connectivity, including: creation and analysis of mathematical models describing the network, proposing self-adaptive control systems in response to node failures, control system parameter optimization, implementation using the software engineering approach, and evaluation in a real application. This thesis also justifies the relations between the "node degree" (the number of neighbor(s) of a node) and network connectivity through mathematic analysis, and proves the effectiveness of various types of controllers that can adjust power transmission of the IoT nodes in response to node failures. The controllers also take into consideration the energy consumption as part of the control goals. The evaluation is performed and comparison is made with other representative algorithms. The simulation results show that the proposals in this thesis can tolerate more random node failures and save more energy when compared with those representative algorithms. Additionally, the simulations demonstrate that the use of the bio-inspired algorithms allows optimizing the parameters of the controller. With respect to the implementation in a real system, the programming model called OSGi (Open Service Gateway Initiative) is integrated with the proposals in order to create a self-adaptive middleware, especially reconfiguring the software components at runtime when failures occur. The outcomes of this thesis contribute to theoretic research and practical applications of resilient topology control for large and distributed networks. The presented controller designs and optimization algorithms can be viewed as novel trials of the control and optimization techniques for the coming era of the IoT. The contributions of this thesis can be summarized as follows: (1) Mathematically, the fault-tolerant probability of a large-scale stochastic network is analyzed. It is studied how the probability of network connectivity depends on the communication range of the nodes, and what is the minimum number of neighbors to be added for network re-connection. (2) A fuzzy-logic control system is proposed, which obtains the desired node degree and in turn maintains the network connectivity when it is subject to node failures. There are different types of fuzzy-logic controllers evaluated by simulations, and the results demonstrate the improvement of fault-tolerant capability as compared to some other representative algorithms. (3) A simpler but more applicable approach, the two-loop control system is further investigated, and its control parameters are optimized by using some heuristic algorithms such as Cross Entropy (CE), Particle Swarm Optimization (PSO), and Differential Evolution (DE). (4) Most of the designs are evaluated by means of simulations, but part of the proposals are implemented and tested in a real-world application by combining the self-adaptive software technique and the control algorithms which are presented in this thesis.

Internet of things virtualization and identity management via fiware generic enablers

La iniciativa FIWARE ofrece un conjunto de APIs potentes que proporcionan la base para una innovación rápida y eficiente en el Internet del Futuro. Estas APIs son clave en el desarrollo de aplicaciones que usan tecnologías muy recientes e innovadoras, como el Internet de las cosas o la Gestión de Identidad en módulos de seguridad. Este documento presenta el desarrollo de una aplicación web de FIWARE usando componentes virtualizados en máquinas virtuales. La aplicación web está basada en “la fábrica de chocolate de Willy Wonka” como una implementación metafórica de una aplicación de seguridad e IoT en un entorno industrial. El componente principal es un servidor web en node.js que conecta con varios componentes de FIWARE, conocidos como “Generic Enablers”. La implementación está compuesta por dos módulos principales: el módulo de IoT y el módulo de seguridad. El módulo de IoT gestiona los sensores instalados por Willy Wonka en las salas de fábrica para monitorizar varios parámetros como, por ejemplo, la temperatura, la presión o la ocupación. El módulo de IoT crea y recibe información de contexto de los sensores virtuales. Esta información de contexto es gestionada y almacenada en un componente de FIWARE conocido como Context Broker. El Context Broker está basado en mecanismos de subscripciones que postean los datos de los sensores en la aplicación, en tiempo real y cuando estos cambian. La conexión con el cliente se produce mediante Web Sockets (socket.io). El módulo de seguridad gestiona las cuentas y la información de los usuarios, les autentica en la aplicación usando una cuenta de FIWARE y comprueba la autorización para acceder a distintos recursos. Distintos roles son creados con distintos permisos asignados. Por ejemplo, Willy Wonka puede tener acceso a todos los recursos, mientras que un Oompa Loopa encargado de la sala del chocolate solo deberías de tener acceso a los recursos de su sala. Este módulo está compuesto por tres componentes: el Gestor de Identidades, el PEP Proxy y el PDP AuthZForce. El gestor de identidades almacena las cuentas de FIWARE de los usuarios y permite la autenticación Single Sing On usando el protocolo OAuth2. Tras logearse, los usuarios autenticados reciben un token de autenticación que es usado después por el AuthZForce para comprobar el rol y permiso asociado del usuario. El PEP Proxy actúa como un servidor proxy que redirige las peticiones permitidas y bloquea las no autorizadas.

A management model for closed-loop supply chains of reusable articles

This PhD dissertation is framed in the emergent fields of Reverse Logistics and ClosedLoop Supply Chain (CLSC) management. This subarea of supply chain management has gained researchers and practitioners' attention over the last 15 years to become a fully recognized subdiscipline of the Operations Management field. More specifically, among all the activities that are included within the CLSC area, the focus of this dissertation is centered in direct reuse aspects. The main contribution of this dissertation to current knowledge is twofold. First, a framework for the so-called reuse CLSC is developed. This conceptual model is grounded in a set of six case studies conducted by the author in real industrial settings. The model has also been contrasted with existing literature and with academic and professional experts on the topic as well. The framework encompasses four building blocks. In the first block, a typology for reusable articles is put forward, distinguishing between Returnable Transport Items (RTI), Reusable Packaging Materials (RPM), and Reusable Products (RP). In the second block, the common characteristics that render reuse CLSC difficult to manage from a logistical standpoint are identified, namely: fleet shrinkage, significant investment and limited visibility. In the third block, the main problems arising in the management of reuse CLSC are analyzed, such as: (1) define fleet size dimension, (2) control cycle time and promote articles rotation, (3) control return rate and prevent shrinkage, (4) define purchase policies for new articles, (5) plan and control reconditioning activities, and (6) balance inventory between depots. Finally, in the fourth block some solutions to those issues are developed. Firstly, problems (2) and (3) are addressed through the comparative analysis of alternative strategies for controlling cycle time and return rate. Secondly, a methodology for calculating the required fleet size is elaborated (problem (1)). This methodology is valid for different configurations of the physical flows in the reuse CLSC. Likewise, some directions are pointed out for further development of a similar method for defining purchase policies for new articles (problem (4)). The second main contribution of this dissertation is embedded in the solutions part (block 4) of the conceptual framework and comprises a two-level decision problem integrating two mixed integer linear programming (MILP) models that have been formulated and solved to optimality using AIMMS as modeling language, CPLEX as solver and Excel spreadsheet for data introduction and output presentation. The results obtained are analyzed in order to measure in a client-supplier system the economic impact of two alternative control strategies (recovery policies) in the context of reuse. In addition, the models support decision-making regarding the selection of the appropriate recovery policy against the characteristics of demand pattern and the structure of the relevant costs in the system. The triangulation of methods used in this thesis has enabled to address the same research topic with different approaches and thus, the robustness of the results obtained is strengthened.

Determinación de las características acústicas de materiales de construcción de Ecuador - Ladrillo artesanal e industrial

En el presente trabajo se plantea el estudio de las características acústicas del ladrillo artesanal e industrial fabricado en Ecuador, considerando las características particulares respecto a la calidad de la materia prima, además del hecho de que a nivel artesanal su producción no está regularizada, si bien existen una serie de reglamentos no siempre son acatados por el productor artesanal, lo que hace que presente propiedades particulares. La idea principal de este trabajo es generar datos referenciales e iniciales, sobre las propiedades acústicas del ladrillo artesanal e industrial ya que en Ecuador, no existe ningún estudio de esta naturaleza sobre el tema. Además de crear los mecanismos necesarios para una posible ampliación del estudio a otros materiales propios de Ecuador que permitan generar una base de datos sobre sus propiedades acústicas. Otro aspecto importante sobre esta investigación es el familiarizarse con el uso de técnicas de medición, manejo de equipamiento y software diverso, del manejo y comparación de normativa. ABSTRACT. The purpose of this paper is the study of the acoustic characteristics of artisanal and industrial brick manufactured in Ecuador, considering the particular characteristics regarding the quality of raw materials, besides the fact that artisanal production level is unregulated, although there are a number of regulations are not always complied with by the artisan producer, which makes this particular properties. The main idea of this paper is to generate reference and baseline data on the acoustic properties of artisanal and industrial brick as in Ecuador, there is no study of this nature on the subject. In addition to creating the necessary mechanisms for a possible extension of the study to other materials from Ecuador that will generate a database on its acoustic properties. Another important aspect of this research is to get familiar with the use of measurement techniques, equipment and miscellaneous management software, management and comparison of legislation.

Higher education in industrial engineering in Peru: towards a new model based on skills

This article analyzes the progress of Industrial Engineering in Peru, the relationship to major trends in Europe and North America, and the projected outlook for the future. It is determined that the need for this engineering specialty includes a significant degree of resource management, and the formation of engineers through education requires not only the acquisition and strengthening of technical knowledge, but also the development of the competences that are required by both employers and the recipients of the benefits of engineering: society. Conclusions have been drawn based on state-of-the-art analyses from Europe and North America, and definitions of trends for engineering.

Educación Superior de la Ingeniería Industrial en el Perú: propuesta de un modelo educativo desde las competencias

El objetivo del presente trabajo de investigación es diseñar un Modelo de Educación que permita formar ingenieros industriales en Perú que sean capaces de enfrentar los retos modernos de fuerte y sostenido crecimiento económico y social. Las necesidades que se han generado a lo largo de los últimos años llevan a identificar que una gran carencia es el poco dominio del concepto, naturaleza y gestión de un proyecto y la marcada ausencia de habilidades humanas y funcionales al momento de ejercer la profesión; entendiendo proyecto como “Un esfuerzo temporal que se lleva a cabo para crear un producto, servicio o resultado único. La naturaleza temporal de los proyectos indica un principio y un final definidos. El final se alcanza cuando se logran los objetivos del proyecto o cuando se termina el proyecto porque sus objetivos no se cumplirán o no pueden ser cumplidos, o cuando ya no existe la necesidad que dio origen al proyecto…. los proyectos pueden tener impactos sociales, económicos y ambientales susceptibles de perdurar mucho más que los propios proyectos.”1. Entonces, formularnos la hipótesis que es posible tener un modelo educativo para la Ingeniería Industrial de Perú que permita y estimule alcanzar estas características tan reclamadas por la sociedad, confiando desde el inicio que su diseño y empleo tendrá fuerte repercusión tanto en el desarrollo personal de los estudiantes, como en el social y económico, por las habilidades y condiciones que serán capaces de desplegar los egresados en sus ámbitos de acción laboral. Para lograr el objetivo se ha hecho una definición de la identidad de la universidad latinoamericana y una verificación de si es posible o no tomar modelos y experiencias de otros lugares y trasladarlos con éxito a escenarios nuevos y distintos. Luego, se han determinado las tendencias más fuertes en la formación de ingenieros industriales en los contextos más exitosos actualmente. Para definir esas habilidades tan reclamadas por el sector público y privado de la sociedad, se busca y define una codificación de competencias genéricas que permite tener un ingeniero moderno bien perfilado para las exigencias globales. Los pasos finales son determinar el Modelo para la Educación Superior de la Ingeniería Industrial de Perú desde las Competencias (MESIC) a partir de novedosos enfoques para la educación como la contextualización, la gestión del conocimiento experto y experimentado, el enfoque socioformativo y la definición de Aspectos Clave del modelo antes de iniciar una planificación curricular de ingeniería. Al final se muestra una aplicación del modelo llegando a detalles de definición de competencias muy interesantes y a la necesidad de contar con un sistema de aseguramiento de calidad de la gestión curricular. Al término de la investigación concluimos que es posible definir un modelo apropiado para formar ingenieros industriales en Perú desde las competencias, capaces de enfrentar los modernos retos locales y globales. También determinamos que el proceso no puede ser impuesto, debe pasar por un transitorio periodo de adecuación de docentes y alumnos y requiere de compromiso, pues se suele enfocar este cambio como una forma de desestimar todo lo anterior, cuando debe entenderse que son procesos complementarios, ya que los importantes logros con clases magistrales y resolución de problemas son evidentes y se trata de estilos diferentes de encarar la educación. El resultado de la imposición puede ser devastador para algunos estudiantes y frustrante para algunos docentes, consecuencias que no se desean y deben evitarse. La aplicación se realiza en una universidad del norte de Perú, la Universidad de Piura, y puede observarse en el último capítulo de este trabajo. ABSTRACT The main objective of this research is to find an Educational Modell in order to train industrial engineers in Peru who are able to face modern challenges of strong and sustained economic and social growth. Over recent years the generated needs have led to understand that a major weakness in our professionals is the poor skills in project management and the marked absence of functional and human skills when exercising the profession. This diagnose has led to formulate the hypothesis that it is possible to have an educational model for Peru Industrial Engineering that allows and encourages to achieve these features which are claimed by society. A project which we trust will have a strong impact from the beginning on both, personal development of students as well as in the social and economic conditions, considering the skills graduates will be able to deploy in their work fields. To achieve the goal first it was defined the identity of the Latin American university and verified whether it is possible or not to take models and experiences elsewhere and move successfully to new and different scenarios. Then there were determined the strongest trends in the industrial engineers training in currently successful contexts. In order to define these demanded skills by the public and private sectors of society, there are defined a set of generic skills that allows to have a modern engineer well profiled for global context. Considering these elements, a Model for Higher Education in Industrial Engineering from Peru Competence (MESIC)is proposed considering novel approaches to education such as territoriality, skilled and experienced knowledge management, socio - formative approach and set the definition of Key aspects of the model before starting a engineering curricular planning. Finally detailed records of an application of the model is shown through modern learning methodologies, development and assessment of skills and the need to have a quality assurance system for entire curriculum management. Through this research it can be concluded that it is possible to determine an appropriate model to train industrial engineers in Peru from the skills, in order to meet the modern local and global challenges. Results show that the process cannot be imposed, instead it must go through a transitional period of adaptation from teachers and students and requires commitment, focusing that this change usually is a way to dismiss the above, and is important to address that there are obvious achievements on education lectures and problem solving, and it should be understood that they are complementary processes. The result of change imposition can be devastating for some students and frustrating for some teachers, unwanted consequences and they should be avoided. The proposed model is applied at a university in northern Peru, the University of Piura, and the results can be seen in the last chapter of this work.

Criação de valor para o cliente: um estudo exploratório sobre programas de Key Account Management (KAM)

Nas últimas décadas, a maturidade de alguns mercados, a globalização e o crescente poder de barganha dos clientes aumentam ainda mais a necessidade das empresas em manterem e desenvolverem de forma eficaz seus clientes mais importantes. Neste contexto, ganham relevância os programas de Key Account Management (KAM), iniciativas corporativas que tratam de forma especial os clientes mais importantes do fornecedor. Para obter o desempenho financeiro superior, o programa de KAM precisa criar valor para o cliente para posterior apropriação de valor pelo fornecedor. Contudo, a maioria dos estudos enfatiza a apropriação de valor pelo fornecedor, porém poucas pesquisas investigam a criação de valor para o cliente em programas de KAM. Além disso, a maioria das pesquisas em marketing de relacionamento ainda foca muito nos impactos positivos do relacionamento. Dessa forma, é importante analisar empiricamente como é a implementação da criação de valor para o cliente em programas de KAM, identificando as principais dimensões e os fatores críticos. O objetivo do presente estudo é analisar o processo de criação de valor para o cliente em programas de Key Account Management (KAM) e propor um modelo de criação de valor para o cliente segundo a perspectiva da empresa fornecedora. As análises e o modelo são elaborados a partir de um processo de investigação abdutiva, ou seja, a combinação entre a fundamentação teórica sobre o conceito de valor e programas de KAM e a análise de conteúdo de 22 entrevistas em profundidade com especialistas em programas de KAM, profissionais de marketing/vendas que trabalham por pelo menos cinco anos com programas de KAM em grandes empresas no Brasil. O modelo proposto explica de forma integrada e sistemática como é a criação de valor para o cliente em programas de KAM segundo cinco dimensões (Desenvolvimento de relacionamentos; Entendimento dos direcionadores de valor; Desenvolvimento da proposta de valor; Comunicação da proposta de valor; e mensuração de valor), quatro moderadores (Orientação relacional do cliente; Formalização do programa de KAM para o cliente; Abordagem do fornecedor: \"orientada ao cliente\" vs. \"orientar o cliente\"; e Fit estratégico entre o fornecedor e o cliente) e três riscos (Não entrega do valor básico para o cliente; Rotatividade do Key Account Manager; e Sentimento de injustiça do cliente). Contribui-se com a teoria sobre o tema, ao incluir uma dimensão específica no modelo para desenvolvimento de relacionamentos do nível da díade (organização-organização) e indivíduo (funcionário-funcionário), e ao abordar não somente aspectos positivos do relacionamento, mas também os aspectos negativos (ou riscos da criação de valor para o cliente). Contribui-se também para a prática, ao prover uma visão mais ampla, sistemática e integradora dos diversos elementos da criação de valor para o cliente aos executivos das empresas que possuem programas de KAM, e ao recomendar práticas organizacionais que servem como guias para a tomada de decisão dos gestores de programas de KAM. Ademais, como a parte empírica do estudo é baseada no contexto brasileiro, amplia-se o conhecimento sobre KAM no Brasil. Por fim, apresentam-se as limitações do estudo com a agenda de pesquisas futuras

Management of social networks in the educational process

The research developed in this work consists in proposing a set of techniques for management of social networks and their integration into the educational process. The proposals made are based on assumptions that have been proven with simple examples in a real scenario of university teaching. The results show that social networks have more capacity to spread information than educational web platforms. Moreover, educational social networks are developed in a context of freedom of expression intrinsically linked to Internet freedom. In that context, users can write opinions or comments which are not liked by the staff of schools. However, this feature can be exploited to enrich the educational process and improve the quality of their achievement. The network has covered needs and created new ones. So, the figure of the Community Manager is proposed as agent in educational context for monitoring network and aims to channel the opinions and to provide a rapid response to an academic problem.

Forms and role of the cluster initiatives in fostering innovation in post-industrial regions: A comparative study of environmental clusters in British West Midlands and Spanish Basque country. ACES Working Paper No. 8, August 2008

The objective of this research is to present cluster initiative approaches in post industrial regions characterized by similar economic history and challenges, with additional emphasis on their role in promoting innovation among regional businesses. The research is based on a comparison study of two environmental industry clusters: Environmental Technology Cluster (ET) from British West Midlands and ACLIMA from Spanish Basque Country. The study analyzes clusters' design and their role in fostering innovation based on environment industry clusters. In both regions environmental industry clusters represent strong potential for further dynamic development with grow opportunities driven by legislation introduced at EU, national or regional levels. The paper compares clusters' heterogeneity, goals and priorities, financing schemes, management structure, types of projects, character of private-public partnerships, challenges, as well as clusters' collaboration at regional/national/international levels. Also focus is given on how the clusters enhance innovation and what types of projects are executed by the regions in this field.
