Semiotic Analysis in the Study of Social Work

Research and professional practices have the joint aim of re-structuring the preconceived notions of reality. They both want to gain the understanding about social reality. Social workers use their professional competence in order to grasp the reality of their clients, while researchers’ pursuit is to open the secrecies of the research material. Development and research are now so intertwined and inherent in almost all professional practices that making distinctions between practising, developing and researching has become difficult and in many aspects irrelevant. Moving towards research-based practices is possible and it is easily applied within the framework of the qualitative research approach (Dominelli 2005, 235; Humphries 2005, 280). Social work can be understood as acts and speech acts crisscrossing between social workers and clients. When trying to catch the verbal and non-verbal hints of each others’ behaviour, the actors have to do a lot of interpretations in a more or less uncertain mental landscape. Our point of departure is the idea that the study of social work practices requires tools which effectively reveal the internal complexity of social work (see, for example, Adams & Dominelli & Payne 2005, 294 – 295). The boom of qualitative research methodologies in recent decades is associated with much profound the rupture in humanities, which is called the linguistic turn (Rorty 1967). The idea that language is not transparently mediating our perceptions and thoughts about reality, but on the contrary it constitutes it was new and even confusing to many social scientists. Nowadays we have got used to read research reports which have applied different branches of discursive analyses or narratologic or semiotic approaches. Although differences are sophisticated between those orientations they share the idea of the predominance of language. Despite the lively research work of today’s social work and the research-minded atmosphere of social work practice, semiotics has rarely applied in social work research. However, social work as a communicative practice concerns symbols, metaphors and all kinds of the representative structures of language. Those items are at the core of semiotics, the science of signs, and the science which examines people using signs in their mutual interaction and their endeavours to make the sense of the world they live in, their semiosis. When thinking of the practice of social work and doing the research of it, a number of interpretational levels ought to be passed before reaching the research phase in social work. First of all, social workers have to interpret their clients’ situations, which will be recorded in the files. In some very rare cases those past situations will be reflected in discussions or perhaps interviews or put under the scrutiny of some researcher in the future. Each and every new observation adds its own flavour to the mixture of meanings. Social workers have combined their observations with previous experience and professional knowledge, furthermore, the situation on hand also influences the reactions. In addition, the interpretations made by social workers over the course of their daily working routines are never limited to being part of the personal process of the social worker, but are also always inherently cultural. The work aiming at social change is defined by the presence of an initial situation, a specific goal, and the means and ways of achieving it, which are – or which should be – agreed upon by the social worker and the client in situation which is unique and at the same time socially-driven. Because of the inherent plot-based nature of social work, the practices related to it can be analysed as stories (see Dominelli 2005, 234), given, of course, that they are signifying and told by someone. The research of the practices is concentrating on impressions, perceptions, judgements, accounts, documents etc. All these multifarious elements can be scrutinized as textual corpora, but not whatever textual material. In semiotic analysis, the material studied is characterised as verbal or textual and loaded with meanings. We present a contribution of research methodology, semiotic analysis, which has to our mind at least implicitly references to the social work practices. Our examples of semiotic interpretation have been picked up from our dissertations (Laine 2005; Saurama 2002). The data are official documents from the archives of a child welfare agency and transcriptions of the interviews of shelter employees. These data can be defined as stories told by the social workers of what they have seen and felt. The official documents present only fragmentations and they are often written in passive form. (Saurama 2002, 70.) The interviews carried out in the shelters can be described as stories where the narrators are more familiar and known. The material is characterised by the interaction between the interviewer and interviewee. The levels of the story and the telling of the story become apparent when interviews or documents are examined with the use of semiotic tools. The roots of semiotic interpretation can be found in three different branches; the American pragmatism, Saussurean linguistics in Paris and the so called formalism in Moscow and Tartu; however in this paper we are engaged with the so called Parisian School of semiology which prominent figure was A. J. Greimas. The Finnish sociologists Pekka Sulkunen and Jukka Törrönen (1997a; 1997b) have further developed the ideas of Greimas in their studies on socio-semiotics, and we lean on their ideas. In semiotics social reality is conceived as a relationship between subjects, observations, and interpretations and it is seen mediated by natural language which is the most common sign system among human beings (Mounin 1985; de Saussure 2006; Sebeok 1986). Signification is an act of associating an abstract context (signified) to some physical instrument (signifier). These two elements together form the basic concept, the “sign”, which never constitutes any kind of meaning alone. The meaning will be comprised in a distinction process where signs are being related to other signs. In this chain of signs, the meaning becomes diverged from reality. (Greimas 1980, 28; Potter 1996, 70; de Saussure 2006, 46-48.) One interpretative tool is to think of speech as a surface under which deep structures – i.e. values and norms – exist (Greimas & Courtes 1982; Greimas 1987). To our mind semiotics is very much about playing with two different levels of text: the syntagmatic surface which is more or less faithful to the grammar, and the paradigmatic, semantic structure of values and norms hidden in the deeper meanings of interpretations. Semiotic analysis deals precisely with the level of meaning which exists under the surface, but the only way to reach those meanings is through the textual level, the written or spoken text. That is why the tools are needed. In our studies, we have used the semiotic square and the actant analysis. The former is based on the distinctions and the categorisations of meanings, and the latter on opening the plotting of narratives in order to reach the value structures.

Motivational profiles of sport event volunteers.

Aim of the study Due to the valuable contribution made by volunteers to sporting events, a better understanding of volunteers’ motivation is imperative for event managers in order to develop effective volunteer re-cruitment and retention strategies. The adoption of working conditions and task domains to the mo-tives and needs of volunteers is one of the key challenges in volunteer management. Conversely, an ignorance of the motives and needs of volunteers could negatively affect their performance and attitude, which will have negative consequences for the execution of events (Strigas & Jackson, 2003). In general, the motives of volunteers are located on a continuum between selflessness (e.g. helping others), and self-interest (e.g. pursuing one’s own interests). Furthermore, it should take into account that volunteers may be motivated by more than one need or goal, and therefore, configure different bundles of motives, resulting in heterogeneous types of motives for voluntary engagement (Dolnicar & Randle, 2007). Despite the extensive number of studies on the motives of sport event volunteers, only few studies focus on the analysis of individual motive profiles concerning volun-teering. Accordingly, we will take a closer look at the following questions: To what extent do volun-teers at sporting events differ in the motives of their engagement, and how can the volunteers be ade-quately classified? Theoretical Background According to the functional approach, relevant subjective motives are related to the outcomes and consequences that volunteering is supposed to lead to and to produce. This means, individuals’ mo-tives determine which incentives are anticipated in return for volunteering (e.g. increase in social contacts), and are important for engaging in volunteering, e.g. the choice between different oppor-tunities for voluntary activity, or different tasks (Stukas et al., 2009). Additionally, inter-individual differences of motive structures as well as matching motives in the reflections of voluntary activities will be considered by using a person-oriented approach. In the person-oriented approach, it is not the specific variables that are made the entities of investigation, but rather persons with a certain combination of characteristic features (Bergmann et al., 2003). Person-orientation in the field of sports event volunteers, it is therefore essential to implement an orientation towards people as a unit of analysis. Accordingly, individual motive profiles become the object of investigation. The individ-ual motive profiles permit a glimpse of intra-individual differences in the evaluation of different motive areas, and thus represent the real subjective perspective. Hence, a person will compare the importance of individual motives for his behaviour primarily in relation to other motives (e.g. social contacts are more important to me than material incentives), and make fewer comparisons with the assessments of other people. Methodology, research design and data analysis The motives of sports event volunteers were analysed in the context of the European Athletics Championships 2014 in Zürich. After data cleaning, the study sample contained a total of 1,169 volunteers, surveyed by an online questionnaire. The VMS-ISA scale developed by Bang and Chel-ladurai (2009) was used and replicated successfully by a confirmatory factor analysis. Accordingly, all seven factors of the scale were included in the subsequent cluster analysis to determine typical motive profiles of volunteers. Before proceeding with the cluster analysis, an intra-individual stand-ardization procedure (according to Spiel, 1998) was applied to take advantage of the intra-individual relationships between the motives of the volunteers. Intra-individual standardization means that every value of each motive dimension was related to the average individual level of ex-pectations. In the final step, motive profiles were determined using a hierarchic cluster analysis based on Ward’s method with squared Euclidean distances. Results, discussion and implications The results reveal that motivational processes differ among sports event volunteers, and that volunteers sometimes combine contradictory bundles of motives. In our study, four different volunteer motive profiles were identified and described by their positive levels on the individual motive dimension: the community supporters, the material incentive seekers, the social networkers, and the career and personal growth pursuers. To describe the four identified motive profiles in more detail and to externally validate them, the clusters were analysed in relation to socio-economic, sport-related, and voluntary work characteristics. This motive-based typology of sports event volunteers can provide valuable guidance for event managers in order to create distinctive and designable working conditions and tasks at sporting events that should, in relation to a person-oriented approach, be tailored to a wide range of individ-ual prerequisites. Furthermore, specific recruitment procedures and appropriate communication measures can be defined in order to approach certain groups of potential volunteers more effectively.

Relevance of motion-related assessment metrics in laparoscopic surgery

INTRODUCTION: Motion metrics have become an important source of information when addressing the assessment of surgical expertise. However, their direct relationship with the different surgical skills has not been fully explored. The purpose of this study is to investigate the relevance of motion-related metrics in the evaluation processes of basic psychomotor laparoscopic skills, as well as their correlation with the different abilities sought to measure. METHODS: A framework for task definition and metric analysis is proposed. An explorative survey was first conducted with a board of experts to identify metrics to assess basic psychomotor skills. Based on the output of that survey, three novel tasks for surgical assessment were designed. Face and construct validation study was performed, with focus on motion-related metrics. Tasks were performed by 42 participants (16 novices, 22 residents and 4 experts). Movements of the laparoscopic instruments were registered with the TrEndo tracking system and analyzed. RESULTS: Time, path length and depth showed construct validity for all three tasks. Motion smoothness and idle time also showed validity for tasks involving bi-manual coordination and tasks requiring a more tactical approach respectively. Additionally, motion smoothness and average speed showed a high internal consistency, proving them to be the most task-independent of all the metrics analyzed. CONCLUSION: Motion metrics are complementary and valid for assessing basic psychomotor skills, and their relevance depends on the skill being evaluated. A larger clinical implementation, combined with quality performance information, will give more insight on the relevance of the results shown in this study.

Supervised classification of minimally invasive surgery psychomotor competence based on instruments motion analysis

Background Objective assessment of psychomotor skills has become an important challenge in the training of minimally invasive surgical (MIS) techniques. Currently, no gold standard defining surgical competence exists for classifying residents according to their surgical skills. Supervised classification has been proposed as a means for objectively establishing competence thresholds in psychomotor skills evaluation. This report presents a study comparing three classification methods for establishing their validity in a set of tasks for basic skills’ assessment. Methods Linear discriminant analysis (LDA), support vector machines (SVM), and adaptive neuro-fuzzy inference systems (ANFIS) were used. A total of 42 participants, divided into an experienced group (4 expert surgeons and 14 residents with >10 laparoscopic surgeries performed) and a nonexperienced group (16 students and 8 residents with <10 laparoscopic surgeries performed), performed three box trainer tasks validated for assessment of MIS psychomotor skills. Instrument movements were captured using the TrEndo tracking system, and nine motion analysis parameters (MAPs) were analyzed. The performance of the classifiers was measured by leave-one-out cross-validation using the scores obtained by the participants. Results The mean accuracy performances of the classifiers were 71 % (LDA), 78.2 % (SVM), and 71.7 % (ANFIS). No statistically significant differences in the performance were identified between the classifiers. Conclusions The three proposed classifiers showed good performance in the discrimination of skills, especially when information from all MAPs and tasks combined were considered. A correlation between the surgeons’ previous experience and their execution of the tasks could be ascertained from results. However, misclassifications across all the classifiers could imply the existence of other factors influencing psychomotor competence.

Metamodelo para la definición de metodologías de desarrollo software centradas en documentos y la mejora de la calidad de la documentación software

La documentación en los proyectos software presenta una serie de problemas que afectan a la calidad del producto y al proceso software. Con frecuencia, la documentación es considerada sólo como un volumen adicional de información disponible para la organización y el equipo de desarrollo, que ralentiza la ejecución del proyecto. En este sentido, el papel de la documentación en un proyecto se concibe como una de las actividades más costosas y que consumen más tiempo y que luego no se utiliza de forma extensiva. La documentación queda, en muchos casos, relegada a un segundo plano y es poco valorada frente a la comunicación cara a cara. Existe además una relación entre la calidad de la documentación y el proceso software. Se plantean dificultades en la adopción de buenas prácticas de proceso software y el impacto del exceso de documentación percibido por parte de los gestores de proyectos en los que se quiere abordad un programa de mejora del proceso software. Recordemos que la calidad de la documentación está muy relacionada con la utilización de la misma que puedan hacer los desarrolladores. Esta tesis aborda el problema planteando un cambio de punto de vista en el proceso software, en el que la documentación pasa de ser un sub producto de las actividades y tareas del proceso a ser el elemento que vertebra el propio proceso. En este nuevo punto de vista, la definición de los propios documentos, sus propiedades y relaciones permiten establecer y guiar procesos software de cualquier tipo. Para ello, desarrolla un metamodelo para definición de metodologías centradas en documentos. Este metamodelo se confronta con una serie atributos de calidad de la documentación software para comprobar que existe una mejora sobre estos, y, por consiguiente se mejora la calidad de la documentación software en general. Por último se utiliza este metamodelo centrado en documentos para describir una metodología ágil (Scrum) y validar la capacidad y flexibilidad del metamodelo utilizando el cambio de punto de vista sobre el proceso software planteado en esta tesis. ABSTRACT The documentation in software projects has a number of problems affecting the quality of the product and the software process. Often, documentation is considered only as an additional volume of information available to the organization and development team, which slows project execution. In this sense, the role of documentation in a project is conceived as one of the most expensive activities and more time-consuming and then not used extensively. The documentation is, in many cases, relegated to the background and is undervalued compared to face-to-face communication. There is also a relationship between the quality of the documentation and software process. There are difficulties in adopting good practices of software process and the impact of excess documentation perceived by project managers in Software Process Improvement activities. We have to remember that quality of the documentation is closely related to the use of it that can make developers. This thesis addresses the problem considering a change of view on the software process, in which the documentation happens to be a by-product of the activities and tasks of the process to be the element that structures the process itself. Through this new view, the definition of the documents themselves, their properties and relationships, allow us to establish processes and guidance for develop software of any kind. To achieve this target, a metamodel for defining document-centric methodologies has been developed. This metamodel confronts a number of quality attributes software documentation to prove that there is an improvement on these, and therefore the quality of the software documentation is improved. Finally this document-centric metamodel is used to describe an agile methodology (Scrum) to validate the capability and flexibility of the metamodel, using the proposed change of view on the software process described in this thesis.

Adapting mode switches into the hierarchical scheduling

Mode switches are used to partition the system’s behavior into different modes to reduce the complexity of large embedded systems. Such systems operate in multiple modes in which each one corresponds to a specific application scenario; these are called Multi-Mode Systems (MMS). A different piece of software is normally executed for each mode. At any given time, the system can be in one of the predefined modes and then be switched to another as a result of a certain condition. A mode switch mechanism (or mode change protocol) is used to shift the system from one mode to another at run-time. In this thesis we have used a hierarchical scheduling framework to implement a multi-mode system called Multi-Mode Hierarchical Scheduling Framework (MMHSF). A two-level Hierarchical Scheduling Framework (HSF) has already been implemented in an open source real-time operating system, FreeRTOS, to support temporal isolation among real-time components. The main contribution of this thesis is the extension of the HSF featuring a multimode feature with an emphasis on making minimal changes in the underlying operating system (FreeRTOS) and its HSF implementation. Our implementation uses fixed-priority preemptive scheduling at both local and global scheduling levels and idling periodic servers. It also now supports different modes of the system which can be switched at run-time. Each subsystem and task exhibit different timing attributes according to mode, and upon a Mode Change Request (MCR) the task-set and timing interfaces of the entire system (including subsystems and tasks) undergo a change. A Mode Change Protocol specifies precisely how the system-mode will be changed. However, an application may not only need to change a mode but also a different mode change protocol semantic. For example, the mode change from normal to shutdown can allow all the tasks to be completed before the mode itself is changed, while changing a mode from normal to emergency may require aborting all tasks instantly. In our work, both the system mode and the mode change protocol can be changed at run-time. We have implemented three different mode change protocols to switch from one mode to another: the Suspend/resume protocol, the Abort protocol, and the Complete protocol. These protocols increase the flexibility of the system, allowing users to select the way they want to switch to a new mode. The implementation of MMHSF is tested and evaluated on an AVR-based 32 bit board EVK1100 with an AVR32UC3A0512 micro-controller. We have tested the behavior of each system mode and for each mode change protocol. We also provide the results for the performance measures of all mode change protocols in the thesis. RESUMEN Los conmutadores de modo son usados para particionar el comportamiento del sistema en diferentes modos, reduciendo así la complejidad de grandes sistemas empotrados. Estos sistemas tienen multiples modos de operación, cada uno de ellos correspondiente a distintos escenarios y para distintas aplicaciones; son llamados Sistemas Multimodales (o en inglés “Multi-Mode Systems” o MMS). Normalmente cada modo ejecuta una parte de código distinto. En un momento dado el sistema, que está en un modo concreto, puede ser cambiado a otro modo distinto como resultado de alguna condicion impuesta previamente. Los mecanismos de cambio de modo (o protocolos de cambio de modo) son usados para mover el sistema de un modo a otro durante el tiempo de ejecución. En este trabajo se ha usado un modelo de sistema operativo para implementar un sistema multimodo llamado MMHSF, siglas en inglés correspondientes a (Multi-Mode Hierarchical Scheduling Framework). Este sistema está basado en el HSF (Hierarchical Scheduling Framework), un modelo de sistema operativo con jerarquía de dos niveles, implementado en un sistema operativo en tiempo real de libre distribución llamado FreeRTOS, capaz de permitir el aislamiento temporal entre componentes. La principal contribución de este trabajo es la ampliación del HSF convirtiendolo en un sistema multimodo realizando los cambios mínimos necesarios sobre el sistema operativo FreeRTOS y la implementación ya existente del HSF. Esta implementación usa un sistema de planificación de prioridad fija para ambos niveles de jerarquía, ocupando el tiempo entre tareas con un “modo reposo”. Además el sistema es capaz de cambiar de un modo a otro en tiempo de ejecución. Cada subsistema y tarea son capaces de tener distintos atributos de tiempo (prioridad, periodo y tiempo de ejecución) en función del modo. Bajo una demanda de cambio de modo (Mode Change Request MCR) se puede variar el set de tareas en ejecución, así como los atributos de los servidores y las tareas. Un protocolo de cambio de modo espeficica precisamente cómo será cambiado el sistema de un modo a otro. Sin embargo una aplicación puede requerir no solo un cambio de modo, sino que lo haga de una forma especifica. Por ejemplo, el cambio de modo de “normal” a “apagado” puede permitir a las tareas en ejecución ser finalizadas antes de que se complete la transición, pero sin embargo el cambio de “normal” a “emergencia” puede requerir abortar todas las tareas instantaneamente. En este trabajo ambas características, tanto el modo como el protocolo de cambio, pueden ser cambiadas en tiempo de ejecución, pero deben ser previamente definidas por el desarrollador. Han sido definidos tres protocolos de cambios: el protocolo “suspender/continuar”, protocolo “abortar” y el protocolo “completar”. Estos protocolos incrementan la flexibilidad del sistema, permitiendo al usuario seleccionar de que forma quieren cambiar hacia el nuevo modo. La implementación del MMHSF ha sido testada y evaluada en una placa AVR EVK1100, con un micro-controlador AVR32UC3A0. Se ha comprobado el comportamiento de los distintos modos para los distintos protocolos, definidos previamente. Como resultado se proporcionan las medidades de rendimiento de los distintos protocolos de cambio de modo.

Análisis de la actividad neuronal y cerebral mediante técnicas de redes complejas

El cerebro humano es probablemente uno de los sistemas más complejos a los que nos enfrentamos en la actualidad, si bien es también uno de los más fascinantes. Sin embargo, la compresión de cómo el cerebro organiza su actividad para llevar a cabo tareas complejas es un problema plagado de restos y obstáculos. En sus inicios la neuroimagen y la electrofisiología tenían como objetivo la identificación de regiones asociadas a activaciones relacionadas con tareas especificas, o con patrones locales que variaban en el tiempo dada cierta actividad. Sin embargo, actualmente existe un consenso acerca de que la actividad cerebral tiene un carácter temporal multiescala y espacialmente extendido, lo que lleva a considerar el cerebro como una gran red de áreas cerebrales coordinadas, cuyas conexiones funcionales son continuamente creadas y destruidas. Hasta hace poco, el énfasis de los estudios de la actividad cerebral funcional se han centrado en la identidad de los nodos particulares que forman estas redes, y en la caracterización de métricas de conectividad entre ellos: la hipótesis subyacente es que cada nodo, que es una representación mas bien aproximada de una región cerebral dada, ofrece a una única contribución al total de la red. Por tanto, la neuroimagen funcional integra los dos ingredientes básicos de la neuropsicología: la localización de la función cognitiva en módulos cerebrales especializados y el rol de las fibras de conexión en la integración de dichos módulos. Sin embargo, recientemente, la estructura y la función cerebral han empezado a ser investigadas mediante la Ciencia de la Redes, una interpretación mecánico-estadística de una antigua rama de las matemáticas: La teoría de grafos. La Ciencia de las Redes permite dotar a las redes funcionales de una gran cantidad de propiedades cuantitativas (robustez, centralidad, eficiencia, ...), y así enriquecer el conjunto de elementos que describen objetivamente la estructura y la función cerebral a disposición de los neurocientíficos. La conexión entre la Ciencia de las Redes y la Neurociencia ha aportado nuevos puntos de vista en la comprensión de la intrincada anatomía del cerebro, y de cómo las patrones de actividad cerebral se pueden sincronizar para generar las denominadas redes funcionales cerebrales, el principal objeto de estudio de esta Tesis Doctoral. Dentro de este contexto, la complejidad emerge como el puente entre las propiedades topológicas y dinámicas de los sistemas biológicos y, específicamente, en la relación entre la organización y la dinámica de las redes funcionales cerebrales. Esta Tesis Doctoral es, en términos generales, un estudio de cómo la actividad cerebral puede ser entendida como el resultado de una red de un sistema dinámico íntimamente relacionado con los procesos que ocurren en el cerebro. Con este fin, he realizado cinco estudios que tienen en cuenta ambos aspectos de dichas redes funcionales: el topológico y el dinámico. De esta manera, la Tesis está dividida en tres grandes partes: Introducción, Resultados y Discusión. En la primera parte, que comprende los Capítulos 1, 2 y 3, se hace un resumen de los conceptos más importantes de la Ciencia de las Redes relacionados al análisis de imágenes cerebrales. Concretamente, el Capitulo 1 está dedicado a introducir al lector en el mundo de la complejidad, en especial, a la complejidad topológica y dinámica de sistemas acoplados en red. El Capítulo 2 tiene como objetivo desarrollar los fundamentos biológicos, estructurales y funcionales del cerebro, cuando éste es interpretado como una red compleja. En el Capítulo 3, se resumen los objetivos esenciales y tareas que serán desarrolladas a lo largo de la segunda parte de la Tesis. La segunda parte es el núcleo de la Tesis, ya que contiene los resultados obtenidos a lo largo de los últimos cuatro años. Esta parte está dividida en cinco Capítulos, que contienen una versión detallada de las publicaciones llevadas a cabo durante esta Tesis. El Capítulo 4 está relacionado con la topología de las redes funcionales y, específicamente, con la detección y cuantificación de los nodos mas importantes: aquellos denominados “hubs” de la red. En el Capítulo 5 se muestra como las redes funcionales cerebrales pueden ser vistas no como una única red, sino más bien como una red-de-redes donde sus componentes tienen que coexistir en una situación de balance funcional. De esta forma, se investiga cómo los hemisferios cerebrales compiten para adquirir centralidad en la red-de-redes, y cómo esta interacción se mantiene (o no) cuando se introducen fallos deliberadamente en la red funcional. El Capítulo 6 va un paso mas allá al considerar las redes funcionales como sistemas vivos. En este Capítulo se muestra cómo al analizar la evolución de la topología de las redes, en vez de tratarlas como si estas fueran un sistema estático, podemos caracterizar mejor su estructura. Este hecho es especialmente relevante cuando se quiere tratar de encontrar diferencias entre grupos que desempeñan una tarea de memoria, en la que las redes funcionales tienen fuertes fluctuaciones. En el Capítulo 7 defino cómo crear redes parenclíticas a partir de bases de datos de actividad cerebral. Este nuevo tipo de redes, recientemente introducido para estudiar las anormalidades entre grupos de control y grupos anómalos, no ha sido implementado nunca en datos cerebrales y, en este Capítulo explico cómo hacerlo cuando se quiere evaluar la consistencia de la dinámica cerebral. Para concluir esta parte de la Tesis, el Capítulo 8 se centra en la relación entre las propiedades topológicas de los nodos dentro de una red y sus características dinámicas. Como mostraré más adelante, existe una relación entre ellas que revela que la posición de un nodo dentro una red está íntimamente correlacionada con sus propiedades dinámicas. Finalmente, la última parte de esta Tesis Doctoral está compuesta únicamente por el Capítulo 9, el cual contiene las conclusiones y perspectivas futuras que pueden surgir de los trabajos expuestos. En vista de todo lo anterior, espero que esta Tesis aporte una perspectiva complementaria sobre uno de los más extraordinarios sistemas complejos frente a los que nos encontramos: El cerebro humano. ABSTRACT The human brain is probably one of the most complex systems we are facing, thus being a timely and fascinating object of study. Characterizing how the brain organizes its activity to carry out complex tasks is highly non-trivial. While early neuroimaging and electrophysiological studies typically aimed at identifying patches of task-specific activations or local time-varying patterns of activity, there has now been consensus that task-related brain activity has a temporally multiscale, spatially extended character, as networks of coordinated brain areas are continuously formed and destroyed. Up until recently, though, the emphasis of functional brain activity studies has been on the identity of the particular nodes forming these networks, and on the characterization of connectivity metrics between them, the underlying covert hypothesis being that each node, constituting a coarse-grained representation of a given brain region, provides a unique contribution to the whole. Thus, functional neuroimaging initially integrated the two basic ingredients of early neuropsychology: localization of cognitive function into specialized brain modules and the role of connection fibres in the integration of various modules. Lately, brain structure and function have started being investigated using Network Science, a statistical mechanics understanding of an old branch of pure mathematics: graph theory. Network Science allows endowing networks with a great number of quantitative properties, thus vastly enriching the set of objective descriptors of brain structure and function at neuroscientists’ disposal. The link between Network Science and Neuroscience has shed light about how the entangled anatomy of the brain is, and how cortical activations may synchronize to generate the so-called functional brain networks, the principal object under study along this PhD Thesis. Within this context, complexity appears to be the bridge between the topological and dynamical properties of biological systems and, more specifically, the interplay between the organization and dynamics of functional brain networks. This PhD Thesis is, in general terms, a study of how cortical activations can be understood as the output of a network of dynamical systems that are intimately related with the processes occurring in the brain. In order to do that, I performed five studies that encompass both the topological and the dynamical aspects of such functional brain networks. In this way, the Thesis is divided into three major parts: Introduction, Results and Discussion. In the first part, comprising Chapters 1, 2 and 3, I make an overview of the main concepts of Network Science related to the analysis of brain imaging. More specifically, Chapter 1 is devoted to introducing the reader to the world of complexity, specially to the topological and dynamical complexity of networked systems. Chapter 2 aims to develop the biological, topological and functional fundamentals of the brain when it is seen as a complex network. Next, Chapter 3 summarizes the main objectives and tasks that will be developed along the forthcoming Chapters. The second part of the Thesis is, in turn, its core, since it contains the results obtained along these last four years. This part is divided into five Chapters, containing a detailed version of the publications carried out during the Thesis. Chapter 4 is related to the topology of functional networks and, more specifically, to the detection and quantification of the leading nodes of the network: the hubs. In Chapter 5 I will show that functional brain networks can be viewed not as a single network, but as a network-of-networks, where its components have to co-exist in a trade-off situation. In this way, I investigate how the brain hemispheres compete for acquiring the centrality of the network-of-networks and how this interplay is maintained (or not) when failures are introduced in the functional network. Chapter 6 goes one step beyond by considering functional networks as living systems. In this Chapter I show how analyzing the evolution of the network topology instead of treating it as a static system allows to better characterize functional networks. This fact is especially relevant when trying to find differences between groups performing certain memory tasks, where functional networks have strong fluctuations. In Chapter 7 I define how to create parenclitic networks from brain imaging datasets. This new kind of networks, recently introduced to study abnormalities between control and anomalous groups, have not been implemented with brain datasets and I explain in this Chapter how to do it when evaluating the consistency of brain dynamics. To conclude with this part of the Thesis, Chapter 8 is devoted to the interplay between the topological properties of the nodes within a network and their dynamical features. As I will show, there is an interplay between them which reveals that the position of a node in a network is intimately related with its dynamical properties. Finally, the last part of this PhD Thesis is composed only by Chapter 9, which contains the conclusions and future perspectives that may arise from the exposed results. In view of all, I hope that reading this Thesis will give a complementary perspective of one of the most extraordinary complex systems: The human brain.

Aprendizaje del baloncesto en Educación Secundaria utilizando el juego: Una propuesta de Investigación-acción.

El baloncesto es un deporte basado en unos principios de juego sencillos y unas exigencias físicas y técnicas en la iniciación asumibles por todos los alumnos. Ofreciendo las herramientas adecuadas y adaptando las tareas de aprendizaje al contexto se puede conseguir una competencia elevada. Es necesario llevar a cabo una planificación adecuada y una selección de tareas apropiadas. El juego posee unas características que le convierten en un elemento con gran potencial educativo, en especial para Educación Física, debido al placer que genera y al espacio que ofrece para expresarse y utilizar el cuerpo. A través de este trabajo se propone una Unidad Didáctica de Baloncesto vertebrada por el uso del juego como elemento vehicular. La Investigación-acción es un proceso que explora directamente sobre el terreno, siendo muy sencillo y práctico para aplicar en el ámbito educativo. Engloba de manera casi simultánea el proceso de investigación y el de búsqueda de soluciones. Para analizar el resultado de dicha metodología se exponen los elementos básicos para llevar a cabo un trabajo de Investigación-acción paralelo y adaptado al Baloncesto y la Unidad Didáctica. Basketball is a sport based on easy game principles. Every student is capable of reaching physical and technical request for amateur practice. High skills in basketball can be obtained with suitable tools and adapted activities to the current environment. Appropriate planning and tasks are required for that purpose. In education game activities turn to be an option with excellent opportunities, especially for physical education. It provides students a way to express feelings, practice with their body and have fun. The aim of this project is to propose a basketball teaching unit focused on gaming tasks. Participatory action research intervenes directly on the field, simple and practical to be used in educational context. This model links researching and problem solving on the same process. The basic path to perform a participatory action research is given to analyze the results of carrying out the proposed teaching unit.

Modelo multidimensional de los factores que afectan la interacción entre marketing y ventas en el lanzamiento de nuevos productos en Latino América

Esta tesis se centra en la identificación y análisis de los factores que pueden favorecer o actuar como barreras del éxito de la implementación de la innovación y las relaciones entre sí, desde el enfoque de la interface marketing-ventas. El trabajo empírico se enmarca en el vacío de investigación existente en el campo del proceso de lanzamiento de nuevos productos en los mercados donde operan subsidiarias de empresas multinacionales de consumo masivo (FMCG). Las empresas FMCG son altamente dependientes de la innovación como proceso clave determinante del crecimiento competitivo de mediano y largo plazo. En un contexto de acortamiento del ciclo de vida de los productos, como resultado del desarrollo tecnológico y científico que impactan en el comportamiento de los consumidores, las empresas invierten un mayor nivel de recursos en el desarrollo de nuevos productos, reingeniería y programas de innovación (Mundra, Gulati y Gupta, 2013). Sin embargo, a pesar del aumento en la inversión, las tasas de éxito de la innovación reportadas son inferiores al 25% (Evanschitzky, Eisend, Calantone y Jiang, 2012). Aumentar las tasas de éxito de los proyectos de innovación es reconocida en la literatura como un elemento clave para la supervivencia y competitividad de las empresas, para ser superiores a su competencia y desarrollar nuevos modelos de negocios. A pesar de la existencia de estudios que intentan comprender el proceso de lanzamiento de nuevos productos, no se ha identificado un claro prototipo de gestión de la innovación (Gupta et al, 2007). Profundizando en los factores de éxito, los autores Keupp, Palmié y Gassman (2012) reconocen que la innovación exitosa no depende solamente de la estrategia de selección de los proyectos de innovación, sino también la forma en que los mismos son implementados (Klein and Sorra, 1996; Repenning, 2002; Keupp, Palmié y Gassmann, 2012). Al analizar la implementación de los proyectos de lanzamiento de nuevos productos al mercado, en empresas FMCG, dicho proceso es responsabilidad principalmente de las funciones de marketing y ventas a través de la comunicación con los consumidores y los clientes respectivamente (Ernst, Hoyer y Rubsaamen, 2010). Es decir que el éxito en la implementación de la innovación requiere la gestión efectiva de la relación inter-funcional entre marketing y ventas (Ernst, Hoyer y Rubsaamen, 2010; Hughes, Le Bon y Malshe, 2012). A pesar de la importancia de la integración entre marketing y ventas en la conceptualización e implementación de la innovación, este tema no ha sido estudiado en profundidad (Hughes, Le Bon y Malshe, 2012; Keupp, Palmié y Gassmann, 2012). En las empresas multinacionales, está demostrado que el desempeño de las subsidiarias determinan el éxito competitivo de la empresa a nivel global. El desafío de dichas subsidiarias es conjugar el desarrollo global de innovación y comunicación con las características locales de comportamiento del consumidor y el mercado. Por lo tanto, esta investigación empírica responde a la pregunta académica y de gestión acerca de cómo mejorar las tasas de éxito de lanzamiento de nuevos productos al mercado en subsidiarias de empresas de consumo masivo, desde la perspectiva de la relación entre marketing y ventas. En particular analiza cómo afectan la formalización de los procesos y los mecanismos de comunicación a la confianza interpersonal y a la efectividad de la interface marketing-ventas y dichos factores a su vez sobre la planificación integrada de la implementación de la innovación. La determinación de los factores o ítems que conforman cada uno de los constructos del proceso de ejecución de la innovación, se llevó a cabo a partir de una revisión exhaustiva del estado del arte de la literatura sobre las interfaces funcionales y el proceso de innovación. Posteriormente, los ítems seleccionados (más de 50 en total) fueron validados por referentes de marketing y ventas de Argentina y Uruguay a través de entrevistas en profundidad. A partir de los factores identificados se construyeron dos modelos teóricos: • (1) relativo a la influencia de las dimensiones de confianza interpersonal sobre la efectividad de las uniones inter-funcionales y como los mecanismos organizacionales, tales como la frecuencia y la calidad de la comunicación entre las áreas, afectan la confianza y la relación entre ellas; • (2) relativo a la dimensión planificación integrada de la implementación de la innovación, ya que durante el lanzamiento de nuevos productos al mercado, marketing y ventas utilizan procesos formales que facilitan la comunicación frecuente y efectiva, desarrollando confianza inter-personal que no solamente afecta la efectividad de su relación sino también el desarrollo de planes integrados entre ambas áreas. El estudio fue llevado a cabo en una empresa multinacional de consumo masivo que integra la lista Global 500 (Fortune, 2015), presente en todo el mundo con más de 25 marcas participantes en más de 15 categorías, implementando 150 proyectos de innovación en el último año. El grupo de subsidiarias en estudio fue reconocido a nivel mundial por su desempeño en crecimiento competitivo y su alta contribución al crecimiento total. El modelo analizado en esta tesis fue expandido al resto de América Latina, tratándose entonces de un caso ejemplar que representa una práctica de excelencia en la implementación de la innovación en subsidiarias de una empresa multinacional. La recolección de los datos fue llevado a cabo a través de un cuestionario estructurado y confidencial, enviado a la base de datos de todo el universo de directores y gerentes de marketing y ventas. El nivel de respuesta fue muy elevado (70%), logrando 152 casos válidos. El análisis de datos comprendió el análisis descriptivo de los mismos, estimación de fiabilidad y análisis factorial exploratorio a través del software SPSS v.20. El análisis factorial confirmatorio y el análisis de senderos para examinar las relaciones entre los factores se estudiaron mediante el software R (Package 2.15.1., R Core Team, 2012) (Fox, 2006). Finalmente se llevaron a cabo entrevistas en profundidad a gerentes de marketing y ventas de cada uno de los seis países con el fin de profundizar en los constructos y sus relaciones. Los resultados de los modelos demuestran que la frecuencia de comunicación impacta positivamente en la calidad de la misma, que a su vez afecta directamente la relación entre marketing y ventas. Adicionalmente, la calidad de la comunicación impacta sobre la confianza cognitiva, que a su vez se relaciona no solamente con la confianza afectiva sino también con la relación entre ambas áreas. Esto significa que para mejorar la implementación de la innovación, los gerentes deberían orientarse a reforzar la relación entre marketing y ventas facilitando la construcción de confianza interpersonal primero cognitiva y luego afectiva, incrementando la frecuencia de la comunicación que alimenta la calidad de la comunicación entre ambas áreas. A través del segundo modelo se demuestra que durante el lanzamiento de nuevos productos al mercado, marketing y ventas necesitan emplear procesos formales que faciliten la comunicación frecuente y efectiva. De esta forma se contrarresta el efecto negativo de la formalización sobre la planificación integrada entre ambas áreas. Adicionalmente, los gerentes de ambos departamentos deberían promover la construcción de confianza interpersonal, no solamente para mejorar la efectividad de la relación, sino también para desarrollar planes integrados de implementación de nuevos productos. Finalmente, se valida que la frecuencia de la comunicación, la confianza afectiva y la relación marketing-ventas, se relacionan positivamente con la planificación integrada en la implementación de la innovación. El estudio contribuye a la comprensión de los factores que las empresas pueden emplear para mejorar la relación inter-funcional entre marketing y ventas y la implementación de la innovación en empresas de consumo masivo. El aporte de esta investigación puede ser valorado de dos maneras, los aportes a la gestión y a la academia. Desde el punto de vista empresarial, provee a los líderes al frente de empresas de consumo masivo, del conocimiento sobre los factores que afectan la implementación de la innovación y en definitiva el éxito del negocio a mediano y largo plazo. Desde el punto de vista académico aporta al conocimiento del proceso de implementación de la innovación y en la efectividad de la interface marketing y ventas en un caso de buenas prácticas en el mercado de consumo masivo. A su vez incorpora por primera vez un estudio empírico en geografías emergentes capaces de recuperar el camino de crecimiento posterior a una profunda crisis económica a través de la exitosa implementación de la innovación en sus mercados. ABSTRACT This thesis is focused on the identification, analysis and relationship study of factors which may benefit or hinder the successful deployment of innovation, from a marketing-sales interface perspective. Considering the non-existent investigation dedicated to the study of new products launches into markets in which Fast Moving Consumer Goods (FMCG) companies’ subsidiaries operate, it is that this investigation has been carried out. FMCG companies rely on innovation as their key process for a competitive growth on a medium and long term basis. Nowadays, the life-cycle of products is getting shorter as a result of new technological and scientific development, having impact on consumer behavior, and therefore companies are forced to dedicating more resources to the development of new products, reengineering and innovation programs (Mundra, Gulati and Gupta, 2013). However, in spite of the investment increase, the innovation success rates have been reported to be lower than 25% (Evanschitzky, Eisend, Calantone y Jiang, 2012). Increasing success rates on innovation processes has been considered as a key element on the survival and competitiveness of companies, outperforming competitors and developing new business models. Despite new studies which try to comprehend the process of new products launch, a prototype of innovation management has not yet been identified (Gupta et al, 2007). Emphasizing on success factors, authors Keupp, Palmié and Gassman (2012) recognize that successful innovation does not solely depend on innovation processes’ selection strategy, but it is also based on the way in which these are implemented (Klein and Sorra, 1996; Repenning, 2002; Keupp, Palmié y Gassmann, 2012). While analyzing the implementation of projects for new products releases on massive consumption companies, the two departments in charge of taking this forward are marketing and sales, by focusing on communication strategies with consumers and clients respectively (Ernst, Hoyer y Rubsaamen, 2010). This means that having success on innovation implementation requires an effective management of inter-functional relationship among marketing and sales (Ernst, Hoyer y Rubsaamen, 2010; Hughes, Le Bon y Malshe, 2012). In spite of the importance on the integration between marketing and sales on the conceptualization and implementation of innovation, this subject has not been studied in depth (Hughes, Le Bon y Malshe, 2012; Keupp, Palmié y Gassmann, 2012). In multinational companies, previous research has confirmed that the performance of their subsidiaries determine the competitive success of the company on a global scale. The challenge of said subsidiaries is to conjugate the global innovation development and communication with the local consumer and market behavior. Therefore, this empirical study aims to respond to the academic and management question of how to improve the success rates of new product launches into MNE subsidiary’ markets, from a marketing-sales relationship perspective. Particularly, this investigation analyses how the formalization of products and communication mechanisms affect interpersonal trust and marketing-sales interface effectiveness and also on how these factors affect the overall planning of the implementation of innovation. The determination of which factors build the hypothesis of the innovation execution process was taken forward through an extensive research on the extant literature on functional interfaces and innovation processes. More than 50 items were selected which were in turn validated by marketing and sales referents on Uruguay and Argentina through in depth interviews. Based on the identified factors, two theoretical models were proposed: (1) Relative to the influence that interpersonal trust dimensions have on inter functional linkages effectiveness and how organizational mechanisms such as frequency and quality of communication between departments affect trust and their relationship. (2) Relative to the integrated planning and innovation implementation dimensions. Marketing and sales department use formal process thus allowing inter-personal trust, which affects positively their relationship and also enables the development of integrated planning between them. The study was performed within a massive consumption company which is part of the “Global 500” (Fortune, 2015), with subsidiaries all over the world and more than 25 participant brands in 15 categories, having implemented over 150 innovation projects in the year under study. The analyzed subsidiary group has been awarded worldwide for their performance in competitive growth and their high contribution to the total growth. The model being analyzed in this thesis was implemented throughout Latin America, representing a remarkable case of innovation implementation excellence for subsidiaries of multinational companies. Data recollection was carried out through a structured and confidential questionnaire, sent to the universe of marketing-sales directors and managers’ database available with a high level of responsiveness of 70%, resulting in 152 valid cases. Data exploration involved a descriptive analysis, followed by a reliability estimation and an exploratory factorial analysis carried out through SPSS v.20. Confirmatory factorial analysis and path analysis (to examine relations between the different study factors) were studied using “R” software (Package 2.15.1., R Core Team, 2012) (Fox, 2006). Finally, in depth interviews were carried out to several marketing and sales managers in each of the six countries so as to further confirm the hypothesis and their relations. The models results prove that communication frequency has a positive impact on the quality of the same, which in turn has direct effects on the marketing-sales relations. Additionally, communication quality has an impact on the cognitive trust, which also relates not only to affective trust, but also to the relation between both areas. This means that in order to improve the implementation of innovation, managers should strive to enforce marketing-sales relations, facilitating the interpersonal trust construction (firstly cognitive, followed by affective trust), increasing the communication frequency, and therefore nurturing the communication quality among both areas. Through the second model, the results confirm the importance of creating effective relationships between sales and marketing to facilitate planning integrated new product implementations. While formalized new product development processes provide opportunities for sales and marketing to communicate, this does not directly influence the planning of integrated new product implementations. By using these formal opportunities to communicate to create information quality, it is possible to improve sales and marketing’s ability to integrate information during the planning process. Further, communication quality creates inter-personal trust in the other party’s competences (cognitive-based trust), leading to affect-based trust. Affect-based inter-personal trust, not only to improve the overall effectiveness of the sales and marketing relationship, but also helps in planning integrated new product implementations. This study contributes to the understanding of factors which enterprises can use to improve the inter-functional relations between marketing and sales, and the implementation of innovation in FMCG companies. The contribution of this investigation can be measured in two ways: enrichment of management and contribution to the academic area. From a business perspective, it provides massive consumption businesses leaders with knowledge on which factors affect innovation implementation, which results on mid and long-term success for the company. From an academic point of view, it provides knowledge on a prototype of successful innovation implementation management based on the marketing-sales interface effectiveness through a case study in the FMCG consumption market. Last but not least, it incorporates for the first time an empiric study on emerging geographies capable of recovery post a deep economic crisis through successful innovation implementation on their markets.

Herramienta EN 301 549: cliente web

En el año 2014 se publicó, bajo mandato de la Comisión Europea, la Norma Europea EN 301 549, titulada “Requisitos de accesibilidad de productos y servicios TIC aplicables a la contratación pública en Europa”. El objetivo de dicha norma es que los productos o servicios TIC (Tecnologías de la Información y la Comunicación) adquiridos por cualquier administración pública europea puedan ser utilizados por personas con diversas características y capacidades, incluyendo a personas con discapacidad. La norma EN 301 549 es compleja, ya que contiene más de 200 requisitos y recomendaciones, que se aplican o no a un producto o servicio TIC en función de las características de dicho producto o servicio. Por ello se ha planteado, desde el Grupo de Investigación en Tecnología Informática y de las Comunicaciones (CETTICO), el desarrollo de una herramienta de soporte a la evaluación del cumplimiento de la norma. La herramienta permitirá a grupos de trabajo anotar los resultados de la evaluación de accesibilidad de un producto o servicio TIC siguiendo los requisitos de la norma Europea EN 301 549. Este trabajo de Fin de Grado se centra en el diseño y codificación del cliente web de la herramienta. Se parte de los resultados de un TFG y un practicum anteriores. En el TFG realizado por Laura Elorrieta [Elorrieta, 2014], se diseñó la interacción del sistema y se evaluó su grado de usabilidad. En el practicum [Montero, 2015], posterior al TFG de Laura Elorrieta, se eligieron las tecnologías web que se iban a utilizar y se realizó el diseño y la implementación mediante prototipos iterativos de la gestión de proyectos de evaluación. El trabajo que se ha realizado en el TFG ha consistido en el diseño de la interfaz de usuario analizando los cambios a realizar en el diseño, debido a los errores de usabilidad conocidos, y la implementación del prototipo funcional de la herramienta. Junto con la parte servidor del TFG de mi compañero Rubén Ortiz Burgos y la interfaz de usuario de este TFG se ha obtenido una aplicación web para realizar evaluaciones de accesibilidad de productos o servicios TIC siguiendo los requisitos de la norma EN 301 549. El prototipo funcional contiene diez páginas web que recogen las diferentes acciones y tareas que pueden realizar los usuarios en función del rol que desempeñen. EL diseño y la implementación se han llevado a cabo empleando las tecnologías web HTML5, CSS3, JavaScript, jQuery y las librerías de Foundation frontend framework.---ABSTRACT---In 2014, under the European Commission mandate, the European standard EN 301 549 has been published under the title “Accessibility requirements applicable to ICT products and procurement services in Europe”. The goal of this standard is that the products or services ICT (Information Communication Technology) acquires by every European public administration can be used by every person with different characteristics and capacities, including those with disability. The rule EN 301549 is very complex, since it has more than 200 requirements and recommendations that can be or not applied to an ICT product or service based on its characteristics of the given product or service. That’s why a development of a support tool has been proposed to the rating of the compliance of the rule, by the Research Group of Informatics Technology and Communication. This tool will allow working groups to record the results of the compliance of accessibility of a product or service following the requirements of the European Standard EN 301549. This Final Degree Work focuses in the design and the coding of the web customer of this tool. The results of a TFG and previous practicums have been used for this. The TFG performed by Laura Elorrieta [Elorrieta, 2014], the interaction of the system was designed and degree of usability was evaluated. In the practicum [Montero, 2015], after the TFG Laura Elorrieta, web technologies used were chosen and the design and implementation were performed using iterative prototyping project management evaluation. The work done on the TFG was to design the users interface to perform analyzing changes in design due to errors known usability and working prototype implementation of the tool. Together with the server part of the TFG my partner Rubén Ortiz Burgos and the user interface done of this TFG it has obtained a web application for the conduct of evaluations accessibility of products or services ICT following the requirements of the EN 301 549. The functional prototype contains ten web sites that collect the various activities and tasks that users can perform based on the role they perform. The design and implementation have been carried out using the technologies web HTML5, CSS3, Java Script, jQuery and the libraries of Foundation fronted framework.

Desarrollo de ontología de títulos de grado

Dada la amplia información que rodea el dominio de programas de estudios superiores, específicamente los estudios de grado, este trabajo fin de grado propone la construcción de un modelo para representar dicha información mediante la construcción de una red de ontologías, proporcionando una definición común de conceptos importantes, y que posteriormente puede ser reutilizada para la construcción de aplicaciones que ayuden a las partes interesadas, como, estudiantes, personal académico y administrativo, a la búsqueda y acceso de información oportuna. Para la construcción de esta red de ontologías, se siguen las recomendaciones y pautas propuestas por la metodología NeOn [1a] [1b], que sigue un paradigma basado en la reutilización de recursos de conocimiento. Por otra parte, se realiza una populación de dicha red de ontologías mediante datos específicos del grado en Ingeniería Informática de la Universidad Politécnica de Madrid. La construcción de una red de ontologías siguiendo las directrices de la metodología NeOn requiere la realización de distintas actividades y tareas, como el estudio del dominio, estudio de la viabilidad, especificación de requisitos, conceptualización, formalización, implementación y mantenimiento. Se realizan también muchas otras actividades y tareas dependiendo del contexto en el que se construye la ontología. En este proyecto se hace un especial énfasis en las actividades de especificación de requisitos, conceptualización e implementación, además de la actividad de búsqueda de recursos ontológicos para su posterior reutilización. Se ha construido una red de ontologías llamada: European Bachelor Degree Ontology (EBDO) que incluye términos y conceptos importantes que se han detectado en la etapa de especificación de requisitos y que las ontologías a reutilizar no contemplan. Las decisiones de diseño para la construcción de esta nueva red de ontologías y su alineamiento con las ontologías a reutilizar se han basado en la especificación de requisitos ontológicos. Una vez definidos los conceptos relevantes de la red de ontologías, se ha implementado la red de ontologías en un lenguaje computable. Una vez que la red de ontologías se ha implementado se han realizado tareas de evaluación para corregir posible errores. Finalmente, cuando se ha obtenido una versión estable de la ontología, se ha realizado la instanciación de individuos del plan de estudios del grado en Ingeniería Informática de la Universidad Politécnica de Madrid.---ABSTRACT---Given the extensive information surrounding the domain of higher education programs, specifically bachelor degree studies, this bachelor degree project proposes the construction of a model to represent this information by building an ontology network, providing a common definition of important concepts. This network can be reused to build semantic applications that help stakeholders, such as, students, academic and organisational staff, to search and access to timely information. For the construction of this network of ontologies, guidelines and recommendations proposed by the NeOn Methodology [1a] [1b] have been followed. This methodology follows a paradigm based on the reuse of knowledge resources. Moreover, a population of this ontology network is performed with specific data of the Computer Science Degree from Universidad Politécnica de Madrid Building a network of ontologies following the guidelines of the NeOn Methodology requires the completion of various activities and tasks such as, the study of the domain, study of the feasibility, requirements specification, conceptualization, formalization, implementation and maintenance. Many other activities and tasks are also performed depending on the context in which the ontology is built. In this project a special emphasis is made on the activities of requirements specification, conceptualization and search of ontological resources for reuse and implementation. A new network of ontologies, named European Bachelor Degree Ontology (EBDO), has been built. This network includes terms and concepts that have been detected at the stage of requirements specification and that the reused ontologies have not contemplated. Design principles for the construction of this new network of ontologies and for the reused ontologies alignment have been based on the ontological specification requirements. Once the relevant concepts of the ontology network are defined, the network has been implemented in a computable ontology language. Once the network ontology is implemented, the evaluation activity has been conducted to correct the errors that the network presented. Finally, when a stable version of the ontology has been obtained, the instantiation of individuals of the study program of the Bachelor Degree in Computer Science from Universidad Politécnica de Madrid has been performed.

Estudo das potencialidades do trabalho prático de orientação investigativa no 1º ciclo do ensino básico

Este estudo insere-se num relatório de estágio, referente ao grau de Mestre em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico, e baseia-se numa problemática assente na análise das potencialidades do trabalho prático de orientação investigativa (TPOI). Tratase de uma pesquisa na prática profissional desenvolvida em contexto de estágio, em duas escolas do 1.º CEB do Concelho de Santarém, que teve ainda como objetivo compreender as dificuldades que se colocam durante a planificação e implementação de atividades POI. Para o efeito, utilizaram-se diferentes instrumentos de recolha de dados: observação, entrevistas e documentos escritos. Ao longo do processo de planificação/implementação/reflexão foram identificadas as principais dificuldades sentidas pela futura educadora/professora nomeadamente a preparação dos guiões e do material, a gestão da turma e as dificuldades dos alunos. Os resultados demonstraram inúmeras potencialidades do TPOI na promoção de aprendizagens ao nível dos conteúdos científicos abordados, dos processos científicos e do trabalho de grupo. Contudo, os resultados permitiram também constatar que um grau de abertura elevado das atividades nem sempre apresenta o efeito desejável nas aprendizagens dos alunos, verificando-se que as características dos alunos e uma maior familiarização com este tipo de atividade é condição essencial para promover a autonomia.

DIVERGÊNCIAS E CONVERGÊNCIAS ENTRE A COMUNICAÇÃO PRIMÁRIA E A COMUNICAÇÃO SECUNDÁRIA NA DIVULGAÇÃO DO CÂNCER DE MAMA

Este estudo investiga as convergências e as divergências na comunicação primária e na comunicação secundária do câncer de mama. Nós usamos um esquema interpretativo fornecido pela Análise de Enquadramento, Agenda Setting, Teoria do Aprendizado Social, Difusão de Inovações, Semiótica e conceito de Novidade na Ciência e no Jornalismo, para argumentar que cientistas e jornalistas comunicam as novidades da Ciência de modos diversos. Também tivemos como uma proposta secundária traçar um panorama histórico da Comunicação da Saúde, e sua evolução, considerando que a Comunicação empreendeu um esforço para legitimar um espaço de encontro com a Saúde, afirmando uma área de aplicação de teorias, princípios e técnicas comunicacionais, com o objetivo preciso de difundir e compartilhar informação, conhecimentos e práticas que contribuam para melhorar os sistemas de saúde e o bem-estar das populações. Através da análise dos dados de periódicos científicos e jornalísticos que divulgam o câncer de mama, nós encontramos apoio significante para nossas predições. As implicações destas diferenças entre a comunicação primária (interpares) e a comunicação secundária (público leigo) para a comunicação da saúde são discutidas, às vezes apresentando-se como convergências, às vezes como divergências. Quando bem esclarecidas e compreendidas, fazem avançar a Comunicação da Saúde, obtendo resultados positivos no bem-estar das populações, considerando que a origem das doen ças está, fundamentalmente, onde se entrelaçam o biológico e o social.(AU)
