Diseño metodológico para la creación y desarrollo de organizaciones innovadoras, basadas en un modelo de liderazgo que genere entornos facilitadores de la creatividad, implantación de procesos de innovación y creación de productos y servicios innovadores

La presente investigación tiene como objetivo el desarrollo de una metodología que favorezca la innovación en las empresas a través de la actividad directiva, analizando a su vez, su influencia a nivel macro, en los sistemas de innovación, en las políticas de innovación y en el capital intelectual y a nivel micro, en la innovación, en el desempeño y en el clima organizacional. Se estima importante realizar un estudio sobre este tema debido a que la innovación se considera un pilar crítico para el desarrollo social a través de la competitividad de las empresas, así como, una fuente importante de ventaja competitiva. Existe abundante literatura sobre la influencia de la innovación en la gestión empresarial y el papel que el liderazgo desempeña en términos generales. Sin embargo, la literatura presenta diversos estilos de liderazgo sin mostrar una línea consistente de interrelación entre ellos, por lo que finalmente no existe una relación sólida entre el liderazgo, la gestión empresarial y la innovación. Este hecho se debe, como se muestra en la tesis, a que la literatura analiza las organizaciones y el liderazgo desde una perspectiva sociológica u organizacional, y otra desde la perspectiva psicológica sin aportar una línea de articulación entre ambas. Es decir, la literatura analiza el comportamiento organizacional pero no su causa. A lo largo de la tesis se van desarrollando diferentes líneas de trabajo que se convierten en aportaciones empíricas y académicas. Así, una de las aportaciones de la tesis es la sustitución de la figura del líder como persona, por la de un directivo con una doble función; por un lado, la función de liderazgo cuyo objetivo es generar cambio y por el otro, la función de gestionar el día a día o desempeño. Sustituir la figura del líder por una doble funcionalidad directiva facilita la comprensión del concepto liderazgo, lo que permite a su vez, establecer estrategias para su desarrollo, haciendo una realidad el que el liderazgo puede ser aprendido. Este resultado constituye la primera aportación de la tesis. Así mismo, a través de un exhaustivo análisis de la literatura, se desarrolla una propuesta de liderazgo integrado de acuerdo con el modelo Stuart-Kotze, el cual se describe también ampliamente. Encontrar un modelo único de liderazgo supone la piedra angular para el desarrollo de la metodología. Esta propuesta de liderazgo integrado da lugar a la segunda aportación de la tesis. Del mismo modo, se realiza un estudio en profundidad de la perspectiva psicológica de las organizaciones desarrollando el constructo Miedo al Error (ME) que resulta ser un rasgo de la personalidad existente en todos los seres humanos y que presenta una influencia negativa tanto en el desempeño, como en la innovación empresarial. Este resultado permite identificar cuales son las verdaderas barreras para el ejercicio del liderazgo, señalando que la disminución del ME debe ser considerada como una competencia de la Inteligencia Emocional a ser desarrollada por los directivos. Este resultado constituye la tercera aportación de la tesis. Una vez desarrollado el modelo de gestión empresarial expuesto, se procede a su validación, analizando la relación entre los constructos que definen el modelo de gestión: el desempeño, la innovación y el ME. Para identificar las influencias o relaciones de causalidad que subyacen entre los constructos, se utilizó la técnica del modelo de ecuaciones estructurales (SEM). La población objeto de estudio estuvo constituida por 350 profesionales con responsabilidad directiva, procedentes de empresas del sector servicios repartidas por toda la geografía española. Como fuente primaria de recolección de información se utilizó el cuestionario desarrollado por Stuart-Kotze M-CPI (Momentum Continuous Performance Improvement). En primer lugar se procedió a evaluar las propiedades psicométricas del modelo de medida, llevándose a cabo un análisis factorial exploratorio (AFE) y un análisis factorial confirmatorio (AFC) de segundo orden. Los resultados obtenidos ponen de manifiesto que el constructo desempeño (D) viene determinado por dos dimensiones, (DOP), desempeño orientado hacia la planificación y (DORT), desempeño orientado hacia la realización de la tarea. Es decir, la muestra de directivos no percibe que la planificación en el día a día y la realización de la tarea estén articuladas. Posteriormente se procede a realizar el contraste del modelo a través del método de ecuaciones estructurales. Los resultados muestran que la relación de influencia de la dimensión DOP no es significativa, por lo que el constructo D queda representado únicamente por la dimensión DORT. Los resultados de la investigación proporcionan conclusiones e hipótesis para futuras investigaciones. Si bien la muestra de directivos realiza un plan estratégico, éste no se tiene en cuenta en el día a día. Este hecho podría explicar el alto grado de administración por crisis tan frecuente en la empresa española. A su vez, el ME presenta una influencia negativa en la innovación, lo que concuerda con la literatura. Al respecto, considerar el ME como un rasgo de la personalidad, presente tanto en directivos como en colaboradores, facilita la comprensión de las barreras de la organización hacia la comunicación abierta a la vez, que una dirección de trabajo para la mejora de la capacidad innovadora de la organización. Por último, los resultados establecen la existencia de una relación causal entre el desempeño diario y la innovación. Con respecto a este segundo resultado y analizando los comportamientos que identifican el constructo D surgen también varias conclusiones e hipótesis para futuras investigaciones. Los resultados ponen de manifiesto que la muestra de directivos genera iniciativas de cambio con la finalidad de que el trabajo diario salga adelante según los estándares de calidad definidos. Sin embargo, estas iniciativas sólo proceden de los directivos, sin participación alguna de los colaboradores, los cuales son sólo responsables de la implementación produciéndose la consiguiente desmotivación y pérdida de oportunidades. Esta conclusión pone de manifiesto que la innovación de las empresas de la muestra sucede para garantizar la eficiencia de los procesos existentes, pero en ningún caso surge de la iniciativa de buscar una mejor eficacia empresarial. Este hecho plantea un origen doble de la innovación en los procesos. La innovación proactiva que buscaría la mejora de la eficacia de la organización y una innovación de carácter reactiva que buscaría la salvaguarda de la eficiencia. Quizás sea esta la causa del gap existente entre la innovación en España y la innovación de los países que ocupan los primeros puestos en el ranking de producción de innovación lo que constituye un importante punto de partida para una investigación futura. ABSTRACT This research aims to develop a methodology that supports innovation in companies through the managers’ activity, analysing in turn its influence at the macro level: innovation systems, innovation policies and Intellectual capital and at the micro level: innovation itself, performance and organizational climate. It is considered important to conduct a study on this subject due to the fact that innovation is considered a critical pillar for the development and future of the enterprise and an important source of competitive advantage. There is abundant literature about the influence of innovation in business management and the role that leadership plays in general terms. However, the literature presents various styles of leadership without showing a consistent relationship among them, so finally there is not a strong relationship among leadership, business management and innovation. As shown in the thesis, this is due to the fact that the literature analyses organizations and leadership from a sociological or organizational perspective and from a psychological perspective, without providing a hinge line between the two. That is, the existing literature discusses organizational behaviour but not its cause. Throughout the thesis, different lines of work that become empirical and academic contributions have been developed. Thus, one of the contributions of the thesis is replacing the figure of the leader as a person, by a manager with a dual function. Firstly, we have the leadership role which aims to generate change and, on the other hand, the function to manage the day-to-day task or performance. Replacing the figure of the leader by a dual managerial functionality facilitates the understanding of the leadership concept, allowing in turn, to establish development strategies and making true that leadership can be learned. This outcome is the first contribution of the thesis. Likewise, through a comprehensive literature review, an integrated leadership proposal is developed, according to the Kotze model, which is also described widely. Finding a specific leadership model represents the cornerstone for the development of the methodology. This integrated leadership proposal leads to the second contribution of the thesis. Similarly, an in-depth study was conducted about the psychological perspective of the organizations disclosing the construct Fear of Failure. This construct is a personality trait that exists in all human beings and has a negative influence on both performance and business innovation. This outcome allows identifying which are the real barriers to the exercise of leadership, noting that the decrease in fear of failure must be considered as an Emotional Intelligence competence to be developed by managers. This outcome represents the third contribution of the thesis. Once a business management model has been developed, we proceed to its validation by analysing the relationship among the model constructs: management, innovation and fear of failure. To identify the influence or causal relationships underlying the constructs, a structural equation model (SEM) technique was used. The study population consisted of 350 professionals with managerial responsibility, from companies in the services sector scattered throughout the Spanish geography. As a primary source for gathering information a questionnaire developed by Kotze M-CPI (Continuous Performance Improvement Momentum) was used. First we proceeded to evaluate the psychometric properties of the measurement model, carrying out an exploratory factorial analysis (EFA) and a confirmatory factorial analysis (CFA) of second order. The results show that the performance construct D is determined by two-dimensions (DOP: performance oriented to planning) and (DORT: aiming at the realization of the task). That is, the sample of managers does not perceive that planning and the daily task are articulated. Then, we proceeded to make the contrast of the model through a structural equation model SEM. The results show that the influence of the DOP dimension is not significant, so that only the DORT dimension finally represents the construct D. The research outcomes provide conclusions and hypotheses for future research. Although the managers in the sample develop a strategic plan, it seems that managers do not take it into account in their daily tasks. This could explain the high degree of crisis management so prevalent in the Spanish companies. In turn, the fear of failure has a negative influence on innovation, consistent with the literature. In this regard, the fear of failure is considered as a personality trait, present in both managers and employees, which enables the understanding of organizational barriers to open communication and provides a direction to improve the organization’s innovative capacity as well. Finally, the results establish a causal relationship between daily performance and innovation. Regarding this second outcome and analysing the behaviours that identify the construct D, several conclusions and hypotheses for future research arise as well. The results show that the managers in the sample show initiatives of change in order to make everyday work go ahead, according to defined quality standards. However, these initiatives only come from managers without any participation of coworkers, which are only responsible for the implementation, and this produces discouragement and loss of opportunities. This finding shows that the innovation by the companies in the sample happens to guarantee the efficiency of existing processes, but do not arise from an initiative that seeks better business efficacy. This raises two sources of innovation in processes. The first source would be a proactive innovation that would seek improved organizational efficacy. The second one is a reactive innovation that would seek to safeguard efficiency. Perhaps this is the cause of the existing gap between the innovation activity in Spain and the innovation activity in those countries that occupy the top positions in the ranking of innovation outcomes. The Spanish companies seek process efficiency and the top innovators business efficacy. This is an important starting point for future research.

Engineering Computational Emotion - A Reference Model for Emotion in Artificial Systems

Emotion is generally argued to be an influence on the behavior of life systems, largely concerning flexibility and adaptivity. The way in which life systems acts in response to a particular situations of the environment, has revealed the decisive and crucial importance of this feature in the success of behaviors. And this source of inspiration has influenced the way of thinking artificial systems. During the last decades, artificial systems have undergone such an evolution that each day more are integrated in our daily life. They have become greater in complexity, and the subsequent effects are related to an increased demand of systems that ensure resilience, robustness, availability, security or safety among others. All of them questions that raise quite a fundamental challenges in control design. This thesis has been developed under the framework of the Autonomous System project, a.k.a the ASys-Project. Short-term objectives of immediate application are focused on to design improved systems, and the approaching of intelligence in control strategies. Besides this, long-term objectives underlying ASys-Project concentrate on high order capabilities such as cognition, awareness and autonomy. This thesis is placed within the general fields of Engineery and Emotion science, and provides a theoretical foundation for engineering and designing computational emotion for artificial systems. The starting question that has grounded this thesis aims the problem of emotion--based autonomy. And how to feedback systems with valuable meaning has conformed the general objective. Both the starting question and the general objective, have underlaid the study of emotion, the influence on systems behavior, the key foundations that justify this feature in life systems, how emotion is integrated within the normal operation, and how this entire problem of emotion can be explained in artificial systems. By assuming essential differences concerning structure, purpose and operation between life and artificial systems, the essential motivation has been the exploration of what emotion solves in nature to afterwards analyze analogies for man--made systems. This work provides a reference model in which a collection of entities, relationships, models, functions and informational artifacts, are all interacting to provide the system with non-explicit knowledge under the form of emotion-like relevances. This solution aims to provide a reference model under which to design solutions for emotional operation, but related to the real needs of artificial systems. The proposal consists of a multi-purpose architecture that implement two broad modules in order to attend: (a) the range of processes related to the environment affectation, and (b) the range or processes related to the emotion perception-like and the higher levels of reasoning. This has required an intense and critical analysis beyond the state of the art around the most relevant theories of emotion and technical systems, in order to obtain the required support for those foundations that sustain each model. The problem has been interpreted and is described on the basis of AGSys, an agent assumed with the minimum rationality as to provide the capability to perform emotional assessment. AGSys is a conceptualization of a Model-based Cognitive agent that embodies an inner agent ESys, the responsible of performing the emotional operation inside of AGSys. The solution consists of multiple computational modules working federated, and aimed at conforming a mutual feedback loop between AGSys and ESys. Throughout this solution, the environment and the effects that might influence over the system are described as different problems. While AGSys operates as a common system within the external environment, ESys is designed to operate within a conceptualized inner environment. And this inner environment is built on the basis of those relevances that might occur inside of AGSys in the interaction with the external environment. This allows for a high-quality separate reasoning concerning mission goals defined in AGSys, and emotional goals defined in ESys. This way, it is provided a possible path for high-level reasoning under the influence of goals congruence. High-level reasoning model uses knowledge about emotional goals stability, letting this way new directions in which mission goals might be assessed under the situational state of this stability. This high-level reasoning is grounded by the work of MEP, a model of emotion perception that is thought as an analogy of a well-known theory in emotion science. The work of this model is described under the operation of a recursive-like process labeled as R-Loop, together with a system of emotional goals that are assumed as individual agents. This way, AGSys integrates knowledge that concerns the relation between a perceived object, and the effect which this perception induces on the situational state of the emotional goals. This knowledge enables a high-order system of information that provides the sustain for a high-level reasoning. The extent to which this reasoning might be approached is just delineated and assumed as future work. This thesis has been studied beyond a long range of fields of knowledge. This knowledge can be structured into two main objectives: (a) the fields of psychology, cognitive science, neurology and biological sciences in order to obtain understanding concerning the problem of the emotional phenomena, and (b) a large amount of computer science branches such as Autonomic Computing (AC), Self-adaptive software, Self-X systems, Model Integrated Computing (MIC) or the paradigm of models@runtime among others, in order to obtain knowledge about tools for designing each part of the solution. The final approach has been mainly performed on the basis of the entire acquired knowledge, and described under the fields of Artificial Intelligence, Model-Based Systems (MBS), and additional mathematical formalizations to provide punctual understanding in those cases that it has been required. This approach describes a reference model to feedback systems with valuable meaning, allowing for reasoning with regard to (a) the relationship between the environment and the relevance of the effects on the system, and (b) dynamical evaluations concerning the inner situational state of the system as a result of those effects. And this reasoning provides a framework of distinguishable states of AGSys derived from its own circumstances, that can be assumed as artificial emotion.

Nuevos mecanismos moleculares de tolerancia a sequía y otros tipos de estrés abiótico en especies arbóreas de interés económico

Las masas forestales tienen una importancia colosal para nuestra sociedad y el conjunto de la biosfera. Estudios recientes a escala mundial indican que la sequía es el factor abiótico que más afecta a su crecimiento y supervivencia, seguida por las temperaturas extremas y la salinidad. Aunque comprender los mecanismos con que las especies arbóreas toleran estas formas de estrés tiene un interés aplicado evidente, dichos mecanismos se han estudiado mucho más en especies herbáceas modelo o de interés agronómico. Existen sin embargo diferencias notables entre ellas, como se demuestra en esta tesis y en otros trabajos recientes. Nuestro estudio se centra concretamente en la respuesta molecular del chopo –el sistema modelo forestal más desarrollado– al estrés abiótico, con particular énfasis en la sequía. Utilizando una estrategia proteómica y tratamientos controlados, hemos identificado componentes mayoritarios de dicha respuesta. Su participación en la misma se ha validado mediante análisis transcripcionales detallados utilizando tecnología qRT-PCR (PCR cuantitativa en tiempo real). Hemos identificado proteínas cuyo nexo funcional con mecanismos de tolerancia ya era conocido, como chaperonas moleculares sHSP o enzimas que atenúan el estrés oxidativo, pero también proteínas cuya relación funcional con el estrés es menos clara o incluso novedosa, como polifenol oxidasas (PPO), deshidrogenasas/reductasas de cadena corta (SDR), o bicupinas (BIC), entre otras. El cuerpo central de la tesis consiste en la caracterización detallada de una PPO inusual, cuya inducción por estrés hídrico se describe por vez primera. Estas enzimas están ampliamente distribuidas en plantas, si bien su número es muy variable de unas especies a otras. Algunas, como nogal, tienen un único gen, mientras que Arabidopsis no tiene ninguno. En la última versión del genoma de chopo hemos identificado un total de 12 miembros bona fide, corrigiendo trabajos previos, y hemos caracterizado su expresión individual ante diferentes situaciones de estrés controlado y tratamientos hormonales. La isoforma antedicha es el único miembro de la familia que responde claramente a la deshidratación. También responde a salinidad y a la mayor parte de tratamientos hormonales ensayados, pero no a daño mecánico o tratamientos con metil jasmonato. Esto la diferencia de enzimas homólogas presentes en otras especies de plantas, que se han relacionado experimentalmente con estrés biótico. Los patrones de acumulación de transcritos en árboles adultos son compatibles con un papel protector frente a la sequía. La integración de nuestros estudios funcionales y filogenéticos sugiere que la familia ha sufrido un proceso reciente de diversificación y neofuncionalización, siendo la protección frente a deshidratación su papel primigenio. Aunque se conoce la actividad bioquímica in vitro de este tipo de enzimas, sus sustratos naturales son esencialmente una incógnita. Mediante expresión heteróloga en Escherichia coli BL21(DE3) hemos detectado que la enzima de chopo es capaz de oxidar L-DOPA a dopaquinona, siendo menos activa frente a otros sustratos. Por otra parte, hemos demostrado su localización cloroplástica mediante transformación transitoria de protoplastos con fusiones a la proteína fluorescente YFP. Mediante la obtención de plantas transgénicas de A. thaliana hemos demostrado que la enzima de chopo aumenta considerablemente la tolerancia in vivo frente a la deshidratación y al estrés salino. El análisis fenotípico detallado de las líneas transgénicas, combinando múltiples metodologías, nos ha permitido sustanciar que la tolerancia tiene una base compleja. Esta incluye una mayor protección del sistema fotosintético, una capacidad antioxidante muy incrementada y la acumulación de solutos osmoprotectores como la prolina. Los análisis metabolómicos nos han permitido asociar la expresión de la proteína a la síntesis de un flavano no descrito previamente en A. thaliana, vinculando la enzima de chopo con la síntesis de fenilpropanoides. También hemos observado alteraciones en los niveles hormonales que podrían subyacer a efectos pleiotrópicos con interés aplicado, como un aumento consistente del tamaño de la planta o el acortamiento del ciclo de crecimiento. Además de aportar datos novedosos sobre la funcionalidad in vivo de esta familia de oxidasas, los resultados de esta tesis demuestran que los árboles son sistemas de estudio interesantes para caracterizar nuevas estrategias de tolerancia al estrés abiótico con potencial aplicado. ABSTRACT Forests masses have an extraordinary importance for our society and the biosphere. Recent worldwide studies indicate that drought is the abiotic factor that affects more their growing and survival, followed by extreme temperatures and salinity. The understanding of how the arboreal species tolerate the stress has an evident practical interest, but their mechanisms have been studied much more in herbaceous species or with agronomic interest. However, considerable differences exist between them, as this thesis and recent studies show. Our study is focused on the molecular response of the poplar –the more developed forestry model system- to abiotic stress, specifically focused in the drought. Using a proteomic strategy and controlled treatments, we have identified main components in such response. Its participation has been validated through transcriptional analysis using qRT-PCR technology. We have identified proteins whose functional connection with tolerance mechanisms were already known, as molecular chaperones sHSP or enzymes that attenuate the oxidative stress, but also some proteins whose functional relationship with the stress is less clear or even novel, as polifenol oxidases (PPO), short chain deshidrogenases/reductases (SDR), or bicupines (BIC), among others. The central body of the thesis consists of the detailed characterization of an unsual PPO, whose induction due to drought stress is first described. These enzymes are thoroughly distributed in plants, but their number of members is very variable among species. Some of them, as the walnut tree, have a single gene, while Arabidopsis has none. We have identified a total of 12 members in the last version of the poplar genome, correcting previous works, and have characterized their individual expression against different situations of controlled stress and hormone treatments. The aforementioned isoform is the only member of the family that responds clearly to the drought. It also reacts to salinity and the majority of hormonal treatments tested, but it does not respond to mechanical damage or treatments with methyl jasmonate. This is the difference with homologue enzymes present in other plant species, which have been related experimentally with abiotic stress. The accumulation patterns of transcripts in adult trees are compatible with a protector role against drought. The integration of our functional and phylogenetic studies suggests that the family has suffered a recent process of diversification and neofunctionalization, being the protection against drought their original role. Although the in vitro biochemistry activity of this kind of enzymes is already known, their natural substracts are essentially a mystery. By means of heterologous expression of Escherichia coli BL21(DE3) we have detected that the enzyme of poplar is able to oxidize L-DOPA to dopaquinone, being less active against other substrates. Additionally, we have proven its chloroplastic location with transitory transformation of protoplasts with YFP protein fusion. By means of getting transgenic plants of A. thaliana, we have demonstrated that the poplar enzyme increases notably the in vivo tolerance against the drought and salinity stresses. The phenotypic analysis of the transgenic lines, and the use of multiple methodologies, allowed us to test the complexity of the tolerance. This includes a major protection of the photosynthetic system, a very increased antioxidant capacity and the accumulation of osmoprotectant solutes as the proline. The metabolic analysis has allowed to associate the protein expression with the synthesis of a Flavan non described previously in A. thalaiana, linking the enzyme of poplar with the synthesis of phenylpropanoids. We have observed alterations in the hormonal levels that could underlie pleiotropic effects with applied interest, as a consistent increase of the size of the plant and the reduction of the growth cycle. The results of this thesis, in addition to provide novel data about the in vivo functionality of the oxidase family, demonstrate that the trees are interesting systems of study to characterize new strategies of tolerance against abiotic stress with applied potential.
