Evaluation of study competence in pupils between 12-14 years old

There are three main study areas of guidance needs for pupils in Compulsory Secondary Education (CSE) which are academic development, personal and social development and the area of professional career. The area of academic development is where the knowledge to be acquired by the pupils, attitudes towards efficient learning in schools and the skills of efficient study are inculcated, the latter being the objective of our study. The research was taken from a sample of 80 school children between twelve and sixteen years old in a Secondary School in Santiago of Compostela ( Spain ). After analysing the results obtained we can see several motivations that justify the need to improve learning and study skills used by pupils. Normative arguments exist, needs that are exhibited by pupils and by teachers, especially tutors, of a scientific nature (connection with academic work) and to develop new strategies taking into account the contributions to the pedagogic research in this field. In this sense the application of an innovative programme of skills and study strategies in communication could be of interest.

Factorial structure and reliability of a perceived influence on selection of a specialized plan of studies, IPEP, in secondary school students of Chillan, Chile

To evaluate these factors, the scale of perceived influences on the election of a specialized plan of studies, IPEP, was built and in this study its factorial structure and reliability were evaluated. The instrument was applied to 115 students, chosen by quote sampling. They were students of a subsidized private secondary school from the city of Chillan, Chile. An exploratory factorial analysis identified eight factors in the scale IPEP: Academic projection, Personal development, Maintenance of the social environment, Academic requirements, Satisfaction of others' expectations, Vocational information, Image of the plan and Family pressure. The results present an initial factorial structure, that empirically and theoretically adequate, whose factors were reliable and conceptually useful. These factors distinguish psychogenic and sociogenic aspects of the vocational process, and allow to initiate diagnostic and investigative actions in relation to this early vocational election that is established in secondary schools of the Chilean educational system

Este artículo recorre la relación entre la experiencia en los oficios del libro (traducción, redacción, corrección) y las nuevas disciplinas académicas (traductología, historia del libro) que las transformaciones de los soportes materiales y financieros han suscitado.

Un elixir de la palabra : Heterogeneidad interlingüe en la narrativa de Sandra Cisneros

Esta tesis doctoral explora la construcción de algunos aspectos enunciativos relacionados con la heterogeneidad lingüístico-cultural presentes en la narrativa de la escritora chicana Sandra Cisneros [n. 1954]. Más específicamente, esta investigación tiene como objetivo principal explicar el fenómeno de la desterritorialización de la lengua a partir del examen de la conformación de espacios lingüístico-culturales intersticiales a lo largo del desarrollo de la obra de Cisneros [1984, 1991, 2002], que conforma el corpus de nuestro trabajo. Nuestra hipótesis rectora indica que en la escritura de Cisneros. La constitución de la heterogeneidad y la gesta del sentido son ineludiblemente interlingües. Así, proponemos que la heterogeneidad interlingüe es la categoría que permite explicar la complejidad discursivo-enunciativa característica de nuestro corpus. A partir del concepto de heterogeneidad[es] enunciativa[s] elaborado por Authier-Revuz [1984]. Definimos la heterogeneidad interlingüe como un fenómeno enunciativo que se inscribe en el ámbito del dialogismo interdiscursivo [Bajtin [1952-3] 1982] y que se manifiesta a través de las marcas y formas que surgen en el discurso a través de los procesos de negociación y traducción Iingüistico-culturales actualizados en el encuentro constante y constitutivo de distintas lenguas. Según entendemos, la heterogeneidad interlingüe se articula a partir de tres dimensiones que se encuentran en permanente interacción: la conformación de una imagen discursiva o ethos [Ducrot, [1984] 1986; Amossy, 1999] asociado al responsable de la enunciación de la totalidad de los textos narrativos [Iocutor-Autor], la institución de sitios -formas y marcas- que se presentan como heterogéneos desde un punto de vista lingüístico-cultural y la configuración de una practica de lectura particular que exige una competencia discursivo-cultural de parte del lector que debe completar el sentido del texto y también del discurso. En atención alas dimensiones aludidas, esta tesis otorga atención específica a los siguientes aspectos: la constitución interlingüe de la paratextualidad, la alternancia de lenguas, los distintos modos de presencia de la traducción, los enunciados paremiológicos y la dimensión reflexiva de la enunciación. Entre los objetivos centrales de nuestra investigación, se cuentan: 1. la elaboración de un andamiaje teórico-metodológico pluridisciplinario que permita dar cuenta de las particularidades discursivas de nuestro corpus y ser referencia para el análisis de otras escrituras de minorías y narrativas de frontera; 2. la contribución al desarrollo de los estudios del discurso [Authier-Revuz, 1984, 1995; Ducrot. [1984] 1986, 2004] a través de la incorporación de la noción de interlingüismo a la discusión de la constitución de la heterogeneidad y de la gesta del sentido discursivo; 3. la articulación del concepto de desterritorializacion [Deleuze y Guattari, [1975] 1998] con algunas nociones originadas en los modelos provenientes de la teoría de la Frontera [Hicks, 1991; Arteaga, 1997] y de la teoría discursiva de Authier-Revuz [1984, 1995]. En cuanto a los objetivos particulares, este trabajo de tesis se propone examinar las distintas formas y marcas de la heterogeneidad interlingüe presentes en la narrativa de Cisneros y ofrecer un panorama analítico que pondere la evolución de la obra de la escritora chicana en relación con la construcción del responsable de la enunciación, los sitios de la heterogeneidad y la practica de lectura singular que impone esta escritura

Description of two mass species of Pacific copepods in terms of two polymorphic loci

Population genetics of two species of mass copepods Undinula darwini and Calanus australis, with different range types, is investigated. Both species exhibit considerable genetic diversity, especially C. australis (observed heterozygoticity = 0.36), which inhabits a variable biotope in the zone of the Peru current. Samples of both species exhibited highly significant genetic heterogeneity as well as heterozygote deficiency compared with the situation expected from the Hardy-Weinberg law. Contribution of distance isolation to genetic differentiation of populations is estimated. Gene drift is discussed as a source of heterogeneity in populations of planktic copepods. Possible aspects of population genetic research on marine plank-tic crustaceans are discussed.

Geochemistry of Early Cretaceous basaltic rocks from ODP Sites 123-765 and 123-766

The Early Cretaceous basaltic rocks obtained from Sites 765 and 766 in the eastern Indian Ocean floor were mostly iron-rich normal mid-ocean ridge basalts (N-MORB), which were derived from a depleted mantle source having strongly light rare earth element (LREE)-depleted rare-earth patterns and a high titanium/zirconium (Ti/Zr) ratio. Basaltic rocks in the upper part of the Site 765 basement section include megacrysts and gabbroic fragments of widely varying mineral chemistry. These megacrysts range from An90 plagioclase, including highly magnesian basaltic glass coexisting with augite of Mg# (= 100 Mg/[Fe+Mg]) at 85, to An50 plagioclase coexisting with hypersthene. This varying mineralogy of megacrysts and gabbroic fragments indicates that a considerable degree of fractional crystallization took place in the magma chamber. The unusual negative correlation between incompatible elements (e.g., TiO2) and FeO*/MgO observed among Site 765 basement basalts and fresh volcanic glasses suggest source-mantle heterogeneity in terms of FeO*/MgO. Strontium isotope ratios (87Sr/86Sr) of the basaltic rocks from both sites are between 0.7027 and 0.7033 and are comparable to those of mid-Indian Ocean ridge basalts (MIORB). The basalt pebbles encountered in the sedimentary section may have been transported from the basement highs nearer the Australian continent and include basaltic compositions ranging from primitive N-MORBs to evolved enriched (E)-MORBs. Their mantle source was not as depleted as that of the basement basalts. These rocks may be the products of earlier volcanism that took place during the rifting of the Australian continent.

An autonomic framework for enhancing the quality of data grid services

Data grid services have been used to deal with the increasing needs of applications in terms of data volume and throughput. The large scale, heterogeneity and dynamism of grid environments often make management and tuning of these data services very complex. Furthermore, current high-performance I/O approaches are characterized by their high complexity and specific features that usually require specialized administrator skills. Autonomic computing can help manage this complexity. The present paper describes an autonomic subsystem intended to provide self-management features aimed at efficiently reducing the I/O problem in a grid environment, thereby enhancing the quality of service (QoS) of data access and storage services in the grid. Our proposal takes into account that data produced in an I/O system is not usually immediately required. Therefore, performance improvements are related not only to current but also to any future I/O access, as the actual data access usually occurs later on. Nevertheless, the exact time of the next I/O operations is unknown. Thus, our approach proposes a long-term prediction designed to forecast the future workload of grid components. This enables the autonomic subsystem to determine the optimal data placement to improve both current and future I/O operations.

Comparison of fractal dimensions based on segmented NDVI fields obtained from different remote sensors.

Satellite image data have become an important source of information for monitoring vegetation and mapping land cover at several scales. Beside this, the distribution and phenology of vegetation is largely associated with climate, terrain characteristics and human activity. Various vegetation indices have been developed for qualitative and quantitative assessment of vegetation using remote spectral measurements. In particular, sensors with spectral bands in the red (RED) and near-infrared (NIR) lend themselves well to vegetation monitoring and based on them [(NIR - RED) / (NIR + RED)] Normalized Difference Vegetation Index (NDVI) has been widespread used. Given that the characteristics of spectral bands in RED and NIR vary distinctly from sensor to sensor, NDVI values based on data from different instruments will not be directly comparable. The spatial resolution also varies significantly between sensors, as well as within a given scene in the case of wide-angle and oblique sensors. As a result, NDVI values will vary according to combinations of the heterogeneity and scale of terrestrial surfaces and pixel footprint sizes. Therefore, the question arises as to the impact of differences in spectral and spatial resolutions on vegetation indices like the NDVI. The aim of this study is to establish a comparison between two different sensors in their NDVI values at different spatial resolutions.

Jerónimo Sánchez Carranza y la Escuela Española de Esgrima

El deporte de la esgrima no siempre ha sido considerado como actualmente se conoce, ni tampoco el empleo de las armas ha sido el mismo en las diferentes épocas de la historia. Si nos centramos en la española, podemos decir que se hablaba de una forma particular de hacer esgrima, la cual era muy apreciada por el resto de los países europeos. También lo era la que se hacía en Italia. Como cualquier actividad que se desarrolla a lo largo del tiempo debe generarse desde unos comienzos. Estos comienzos siempre están en relación a alguna causa. Para centrarnos en nuestro estudio, los comienzos del manejo de la espada, de una manera lógica y razonada, se une en la persona y en la vida de Jerónimo Sánchez Carranza porque hasta que él no se decide a estudiar en profundidad la ciencia de las armas, no se ve con claridad si todo lo que se hacía con ellas era correcto o no y si todo lo que la inmensa mayoría hacía cuando tenía que utilizarlas estaba revestido de cierta coherencia y fundamento, es decir, tenía su verdad que se pudiera demostrar. Carranza estudia la esgrima que se empleaba en su época y en las anteriores y se da cuenta que tiene que dar una nueva visión de la forma de usar las armas, diferente a lo que la gran mayoría entendía hasta entonces. A Carranza se le ha considerado por muchos autores como el inventor de la esgrima española, hecho que se puede leer con bastante facilidad si se hojea algún tratado que hable de la esgrima española, sin embargo también se habla de Luis Pacheco de Narváez asignándole el mismo calificativo, aunn- ;o es posteriora Carranza. or tanto nuestro estudio se ha centrado en la vida de Jerónimo Sánchez Carranza y en ueva forma de emplear las armas por lo que hace que la tesis sea una tesis biográfica de dicho personaje, donde se ha resaltado mucho más el aspecto del manejo de las armas, de la Destreza. Partimos de las siguientes hipótesis: Carranza es el que sienta los principios técnicos dando forma y coherencia a la escuela de esgrima española gracias a sus aportaciones en los distintos aspectos metodológicos, técnicos y tácticos. La escuela de esgrima española tiene una estructura interna, responde a unas características determinadas y sirve de base a la esgrima que posteriormente se practica. Para que el estudio se pudiera llevar a cabo tuvimos que diseñar un esquema donde se pudieran recoger todos los aspectos que estuvieran relacionados con nuestro autor, de ahí surge el porqué de cada uno de los capítulos que hemos confeccionado. Dicho esquema responde a la visión actual de diferentes facetas de lo que hoy se estudia en diversas ciencias y que cuando Carranza vivía aún no se conocían. Para recoger información sobre su persona y su obra tuvimos en cuenta los distintos lugares donde se podía localizar la documentación necesaria, sobre todo Bibliotecas y Archivos, para ir confeccionando el método de trabajo que consistió en la recopilación de fuentes de todo tipo referidas al tema, pasando luego a la interpretación de las mismas. Esto nos dio una visión de conjunto que hizo que nos adentráramos en aquellos aspectos que más tarde tendríamos que analizar con mucho más detenimiento. En la tesis se puede observar dos partes bien diferenciadas que son las relacionadas; por un lado, a su vida y su tratado y, por otro, al contenido de sus teorías que son realmente las que se deben analizar necesariamente bajo unos conocimientos específicos de la actividad de la esgrima. En cuanto a su vida, se han destacado y estudiado los hechos más importantes de los que hay que resaltar, sobre todo, el que fuera considerado como el inventor de la destreza y de la manera tan particular de concebir dicho arte, diferente a lo que hasta ahora se venía haciendo y que dio paso a lo que se entendió por esgrima científica, quedando plasmada de tal manera que dio pie a la creación de una doctrina y una nueva forma de entender la esgrima la cual generó una línea de actuación que fue continuada por numerosos seguidores. Para todo ello tuvo mucho que ver el que Carranza fuera militar, la cultura y los estudios que poseía, así como la situación en la que se encontraba España además de la gente con quien se relacionaba, que por lo general, era gente culta y de clase social alta. Se ha estudiado también dentro del mismo apartado de su vida unos hechos que se le imputan y que en nuestra opinión son erróneos. Hemos considerado como más relevantes el que Carranza no fue quien riñó con Quevedo como se afirma en algunas de las obras que hemos tratado, sino que fue Pacheco quien tuvo dicha riña, ya que más bien Quevedo se mostraba partidario de las enseñanzas de Carranza, estando en contra de Pacheco. Tampoco fue quien inventó el florete como se dice en algunas ocasiones, ya que el florete aparece posteriormente como un arma de estudio de la técnica de la esgrima. Con respecto al apartado de su obra, se debe decir que tan solo escribió un único tratado que se publicó en 1582, aunque estaba acabado desde el año 1569. En el apartado de su escuela se debe destacar los fundamentos en los que basó sus postulados para que la destreza alcanzara el mismo nivel de las demás artes liberales y que lo hizo a través del estudio de la propia destreza. A lo largo del estudio que hemos realizado se puede apreciar cómo se está generando un arte que hasta ahora no había sido estudiado, viéndose los problemas que ello suponía, desde la organización de la materia a tratar, hasta cómo se debía enseñar, pasando a veces a tener que denominar conceptos de nueva aparición o renombrar y modificar antiguos que estaban anclados en puntos de partida equivocados, siendo éstos los que mayor trabajo le supuso. Diferencia bien dos aspectos básicos que debían existir en cualquier arte y más concretamente en la destreza que son: la teoría y la práctica, ambas deben estar en base a la razón ya que sería una de las formas por la que la destreza perduraría en el tiempo, junto con que esta razón estuviera apoyada en otras ciencias y con los principios de ellas. Carranza fue de la opinión de que el diestro debía conocer mediante el estudio, los elementos fundamentales con los que había que trabajar la destreza, estos elementos son el cuerpo del diestro y las armas, porque ambos van a intervenir en cualquier gesto o acción que se vaya a realizar. Del cuerpo estudió cada una de las partes que más importancia tiene cada vez que el diestro interviene y lo hace sobre todo en base a la medicina, relacionándolo con las matemáticas para poder sacar el máximo provecho, aconsejando que por el conocimiento del propio cuerpo, como el del contrario, se podrá emplear en determinadas situaciones, que si no se supiera de ello, no se sacaría el mismo resultado. De las armas lo que más resaltó fue, por un lado, que la espada debía ser el único arma que el diestro debía utilizar y, por otro, el hecho de que la espada la graduara para poder demostrar que no se hacia todo igual con las distintas partes de la misma porque no todo el arma tenía las mismas propiedades cuando se actuaba con ella. Una de las recomendaciones que dio fue que con la parte más próxima a la empuñadura se debía practicar la defensa por tener más fuerza con esta parte que con la punta y lo demostró con principios matemáticos. Se puede ver con la lectura de la tesis cómo Carranza aporta una nueva forma de trabajo en la que le da mucha importancia a la aplicación de los conocimientos, que previamente se han adquirido y para ello, es importante conocer bien los puntos fuertes y débiles del adversario. La adquisición de la práctica se debe realizar a través de la repetición para crear el hábito necesario que haga que el gesto salga fluido en cada uno de los movimientos que el diestro ejecute. Todo esto no sería posible si quien lo enseña no conoce cada uno de los elementos que intervienen en la destreza, por tanto, a la figura del maestro le da un lugar de una gran relevancia, ya que va a ser él quien tenga que guiar a los alumnos que enseñe. Lo primero que debe hacer los maestros es procurar saber lo máximo de la materia que va a enseñar, por lo que el maestro debe saber casi todo sobre la teoría y la práctica de la destreza, pero además esta teoría y práctica debe ser la correcta. Carranza persigue con su estudio, establecer los principios de la destreza, por lo menos, los más importantes, aunque fueran elementales, para que posteriormente se siguiera trabajando sobre ellos y poder conseguir que la destreza tenga cuerpo y forma de arte liberal, pudiéndose estudiar como cualquier otra, así de esta manera se haría un bien público, ya que los jóvenes se instruirían eficazmente en el uso de las armas, aunque el verdadero fin se encuentra en la conservación de la vida como manda la Fe Católica, siendo la destreza uno de los medios más eficaces para conseguirlo. Hemos dedicado un apartado de técnica y de táctica donde se refleja todo lo relacionado con las posiciones y movimientos que debe realizar el diestro para llegar a conseguir su objetivo, que es herir sin ser herido. Se han analizado las distintas tretas y el porqué de cada una desde el punto de vista del gesto y del movimiento. Si lo que se hace en destreza se relaciona con el adversario, nos adentramos en el terreno de la táctica donde se han estudiado como más importantes los conceptos del tiempo y la distancia, así como las energías que debe conservar el diestro para poder llevar a cabo un combate y del mismo salir victorioso sin llegar al agotamiento. Concluimos diciendo que de todo el estudio que se ha realizado, se ha podido comprobar que Carranza fue quien dotó a la destreza de unos principios técnicos, tácticos y metodológicos, por su forma de concebir este nuevo arte, así como que por la manera en que estableció sus teorías hizo que la destreza que se practicaba en España disfrutara de una estructura interna coherente que perduró a través de los años. SUMMARY The sport of fencing has not always been the respected sport that we know it to be today ñor has the use of weapons been the same throughout history. If we concéntrate on Spainish weapons, we can say that one particular type of sword ¡s spoken about. this sword being very respected by outher European countries, it was also the one that was respected and used in Italy. As with any activity that develops in time, it must evlove from some simple beginnings. Such basics beginnings are always in relation to a cause. To concéntrate on our study, the beginnings are, the use of the sword in a reasoned and logical manner, brought together in the life and times of Jerónimo Sánchez Carranza because until he decided to study in depth the science of weapons, we cannot see with calrity if their use was correct or not and if the vast majority , when they had to use them, used any foundation or coherence, that ¡s to say if any exactness of logical use could be demonstrated. Carranza studied the sword used in his time and those that had gone before, bearing in mind that he had a new visión of the form of use of weapons, different to what the vast majority had until then understood. Carranza has been considered by many historians as the inventor of the Spanish sword, a fact which can be seen with relative ease if one flicks through any work which deals with the Spanish sword, however, they also speak of Luis Pacheco de Narváez affording him the same title, even though he followed Carranza. In ar H our study has been centred on the life of Jerónimo Sánchez Carranza and his ne-" use of weapons. In effect this thesis is a biographical thesis of the said wherein the aspect of the use of weapons stands out more than their mastery. Given the following hypothesis: It was Carranza who evolved the first techniques giving form and coherence to the .Spanish School of Fencing, thanks to his contributions to the different aspects of method, íechnique and tactic. The Spanish School of Fencing had an ¡nternal structure anaswerable to pre-detremined characteristics and served as a base for the fencing that was to, in later days, be practised. For this study to come to a head, we had to design a plan wherein we could collate all of the aspects we could, related to our inventor. From there springs the reason for each of the chapters that we have put together. The said plan responding to the actual visión of different facets that are studied today in different sciences, that were not known in Carranza's lifetime. To collect information on his person and his works we bore in mind the different places in which we could lócate the necessary documentation, above all in libraries and archives. Developing the work-method that consisted in extracing from every source, every thing relative to the theme, re-writing later our interpretation of the same. This brought us closer and made us focus of those aspects that much later we would have to analize in greater detail. In the thesis one can observe two defferent parts that are related; on the one hand his life and works and on the other his theories, which are those that should be really analised and as such, necessarily analised within the confines of a specific knowledge of fencing. In that his life has been isolated and studied the most important facts that stand out above all, is that he was considered to be the inventor of swordmanship and the particular manner of interpreting the said art, different to its interpretaion uptil then. It gave a footing to what they understood as scientific fencing, giving shape and form to the creation of a doctrine and a new form of fencing which developed a line of action that was continued by numerious followers. For all that, much had to do with the facts that Carranza was a military man, the culture, the level of studies he had and the situation in which he found himself. What's more the people with whom he mixed were, in general, cultured and of high social standing. We have also seen in the same article on his life some dubious facts which in our opinión are erróneos. We have considered the most relevent to be that it wasnt Carranza who was in dispute with Quevedo as is stated in some of the works with which we have dealt but rather it was with Pacheco he had such disputes. What's more Quevedo demonstrated his partiality to the teachings of Carranza, going against Pacheco ñor was it him who invented The Florete, a famous Spanish sword, as was said on some ocassions, eventhough the florete appeared later as a weapon in the study of fencing technique. With respect to the article on his works, we must say that there was only one article which was published in 1582, even though it was finished in 1569. In the article on his life one must distinguish between the foundations on which he based his teachings in which swordmanship reached the same levéis as other libral art forms and what he did through the study of the self same mastery. Throughout the study which we have done, one can appreciate how he was developing an art which uptill then had not been studied, seeing for himself the problems he had fortold, from the organisation of materials at hand to how it should be taught, at times having to domínate comparative concepts again or clarify and modify ones which were anchored in erróneos points of a fencing match, feeling these to be the main forseeable jobs-at-hand. Differenciating between two basic concepts which must exist in whatever arte form and more concretly in the skill that is; the theory and practice , both being fundamental to the reason why the skill endured through time, together with this reason he was supported by other sciences and the beginnings of such. Carranza was of the opinión that the swordsman must acquired by way of study, the fundemental elements with which he had to work, these elements being the body of the swordsman and the weapons, because both were going to intervene in whatever movement or action that was going to be taken. The body studied, each of the parts having more importance each time the skill intervened and above all what it did based on medicne relating it to matemathics to exact the máximum advantage, one could employ in certain circumstances, that if they were not employed, the same advantages would not result. On weapons, what resulted best was, on the one hand, the sword should be the only weapon that the swordsman should use and on the other hand, the sword should be graded to show that one cannot do the same with the different parts of the same because not all of the weapon had the same properties when used. One of the recomendations he made was that the part nearest to the hand-guard should be used for defence because one could use more forcé with it than the point and he demonstrated this with mathematical principies. One can see on reading this thesis how Carranza brought forth a new work form, in which he put much importance on the application of experience that had previously been acquired and because of it, it was important to know well the strenghts and weaknesses of an adversery. The acquisition of technique should be realised through repetition to form the habit necessary for movement to flow freely each time the swordsman executed a movement. None of this would be possible if whoever was teaching did not know each one of the elements that intervened, affording the fencing master a great reverence, in that it was he who had to guide the students he was to teach. The first thing that the master had to do was to make sure he had the maximun knowledge over which he was going to teach, to that end, the master had to know almost everything about the theory and practice of the skill of fencing but what's more that such theory and practice had to be the correct one. Carranza persued his studies, establishing the principies of technique, at least, the most important ones even though they were elementary, so that later they could continué working on them and it could be seen that the technique had a shape and form of any other art form, allowing it to be studied like any other form, as such it had a good following, even young people could be instructed in the correct use of weapons, however the real end could be found in the conservaron of life as ordered by the Catholic Church, feeling that skill with the sword was one of the most effective methods for assuring it. We have dedicated an article to technique and tactics wherein is reflected everything related to positions and movement that the swordsman must do to achieve his objective, that is, wound without being wounded. We have analised the different tricks and the reasons from every point of view of movement and action. If what is done by technique is related with the adversery we enter in the territory of tactics wherein we have studied, most importantly, the concepts of time and distance just as, the energy the swordsman muse conserve to bring to a head a bout and arrive victorious without being exhausted. We conclude by saying that everything that has been realised by this study, has shown that it was Carranza who gave to the skill, the first basic techniques, tactics and methodology, by his conception of this new art form, just as the manner in which he established his theories, made possible the tecnhiques practiced in Spain would enjoy an intemal coherent structure, which would endure throughout the years.

Policy processes and collective action in water reforms: the cases of Nicaragua and Suriname

Las reformas de agua en países en desarrollo suelen llevarse a cabo junto con cambios institucionales más profundos o, incluso, acompañadas de cambios constitucionales o de régimen político. Por lo tanto, los marcos institucionales adaptados a países gobernados sujetos al estado de derecho pueden no ser apropiados para contextos gobernados fundamentalmente, al menos en sus inicios, por instituciones informales o poco maduras. Esta tesis toma las reformas de agua como punto de partida y pretende contribuir a la literatura mediante una serie de análisis empíricos tanto del ámbito general como del plano individual o sujeto personal de la política del agua. En el ámbito general, el foco se pone en los factores que explican el fallo de la acción colectiva en dos contextos diferentes: 1) en la implementación de la nueva Ley de Aguas de Nicaragua y 2) en el mantenimiento y revitalización de las instituciones de riego en Surinam. En el plano del individuo, la investigación se centra en las decisiones de los usuarios de los recursos y analiza el papel crítico de las variables sociales para la gestión de los recursos comunes. Para ello, el método de investigación utilizado es mixto, combinando el análisis de entrevistas, encuestas y experimentos. En el ámbito general, los resultados muestran que las principales barreras para la implementación de la nueva Ley de Aguas de Nicaragua podrían tener su reflejo en el lenguaje de la Ley y, por tanto, en la forma en la que se definen y configuran las instituciones incluidas en dicha Ley. Así, la investigación demuestra que la implementación de políticas no puede ser estudiada o entendida sin tener en cuenta tanto el diseño de la propia política como el marco socio-ecológico en el que se enmarca. El contexto específico de Nicaragua remarca la importancia de considerar tanto las instituciones formales como informales en los procesos de transición política. A pesar de que las reformas de agua requieren plazos largos para su implementación, el hecho de que exista una diferencia entre las reglas tal cual se definen formalmente y las reglas que operan en la realidad merece una mayor consideración en el diseño de políticas basadas fundamentalmente en instituciones formales. En el ámbito de la conducta individual, el análisis de la acción colectiva ofrece una serie de observaciones empíricas interesantes. En el caso de Nicaragua, los resultados indican que la intensidad de las relaciones sociales, el tipo de agentes dispuestos a proporcionar apoyo social y el nivel de confianza en la comunidad son factores que explican de manera significativa la participación en la comunidad. Sin embargo, el hecho de que la gestión colectiva de riego se produzca, en la mayoría de casos, en torno a lazos familiares sugiere que las variables de capital social críticas se definen en gran medida en la esfera familiar, siendo difícil que se extiendan fuera de estos nexos. El análisis experimental de los resultados de un juego de uso de recurso común y contribución al bien público muestra que las preferencias pro-sociales de los individuos y la heterogeneidad del grupo en términos de composición por sexo son factores que explican significativamente los resultados y las decisiones de apropiación a lo largo del juego. En términos del diseño de las políticas, es fundamental tener en cuenta las dinámicas de participación y uso de los recursos comunes de manera que los niveles de cooperación puedan mantenerse en el largo plazo, lo cual, como se observa en el caso de Surinam, no es siempre posible. Finalmente, el caso de Surinam es un ejemplo ilustrativo de los procesos de acción colectiva en economías en transición. El análisis del fallo de la acción colectiva en Surinam muestra que los procesos políticos vinculados al período colonial y de independencia explican en gran medida la falta de claridad en las reglas operacionales y colectivas que gobiernan la gestión de los sistemas de riego y drenaje. Los resultados empíricos sugieren que a pesar de que la acción colectiva para la provisión de los servicios de riego y drenaje estaba bien establecida bajo el régimen colonial, la auto-organización no prosperó en un contexto dependiente del apoyo externo y regido fundamentalmente por reglas diseñadas al nivel competencial del gobierno central. El sistema socio-ecológico que se desarrolló durante la transición post-colonial favoreció, así, la emergencia de comportamientos oportunistas, y posteriormente la inoperancia de los Water Boards (WBs) creados en la época colonial. En este sentido, cualquier intento por revitalizar los WBs y fomentar el desarrollo de la auto-organización de los usuarios necesitará abordar los problemas relacionados con los patrones demográficos, incluyendo la distribución de la tierra, el diseño de instituciones y la falta de confianza en el gobierno, además de las inversiones típicas en infraestructura y sistemas de información hidrológicos. El liderazgo del gobierno, aportando empuje de arriba-abajo, es, además, otro elemento imprescindible en Surinam. ABSTRACT Water reforms in developing countries take place along deeper institutional and even constitutional. Therefore, institutional frameworks that might result in positive outcomes in countries governed by the rule of law might not fit in contexts governed mainly by informal or immature institutions. This thesis takes water reforms as the starting point and aims to contribute to the literature by presenting several conceptual and empirical analyses at both general and individual levels. At the general national level, the focus is on the factors explaining failure of collective action in two different settings: 1) in the implementation of the new Nicaraguan Water Law and 2) in sustaining and revitalizing irrigation institutions in Suriname. At the individual level, the research focuses on the actions of resource users and analyzes the critical role of social variables for common pool resources management. For this purpose, the research presented in this thesis makes use of a mixed-method approach, combining interviews, surveys and experimental methods. Overall, the results show that major barriers for the implementation of the new Nicaraguan Water Law have its reflection on the language of the Law and, therefore, on the way institutions are defined and configured. In this sense, our study shows that implementation cannot fruitfully be studied and understood without taking into account both the policy design and the social-ecological context in which it is framed. The specific setting of Nicaragua highlights the relevance of considering both formal and informal institutions when promoting policy transitions. Despite the unquestionable fact that water reforms implementation needs long periods of time, there is still a gap between the rules on paper and the rules on the ground that deserves further attention when proposing policy changes on the basis of formal institutions. At the level of the individual agent, the analysis of collective action provides a number of interesting empirical insights. In the case of Nicaragua, I found that the intensity of social networks, the type of agents willing to provide social support and the level of trust in the community are all significant factors in explaining collective action at community level. However, the fact that most collective irrigation relies on family ties suggests that critical social capital variables might be defined within the family sphere and making it difficult to go beyond it. Experimental research combining a common pool resource and a public good game in Nicaragua shows that individuals’ pro-social traits and group heterogeneity in terms of sex composition are significant variables in explaining efficiency outcomes and effort decisions along the game. Thus, with regard to policy design, it is fundamental to consider carefully the dynamics of agents' participation and use of common pool resources, for sustaining cooperation in the long term, which, as seen in the case and Surinam, is not always possible. The case of Suriname provides a rich setting for the analysis of collective action in transition economies. The analysis of decay of collective irrigation in Suriname shows that the lack of clear operational and collective choice rules appear to be rooted in deeper political processes that date back to the colonial period. The empirical findings suggest that despite collective action for the provision of irrigation and drainage services was well established during the colonial period, self-organization did not flourish in a context governed by colonial state-crafted rules and mostly dependent on external support. The social-ecological system developed during the post-colonial transition process favored the emergence of opportunistic behavior. In this respect, any attempt to revitalize WBs and support self-organization will need to tackle the problems derived from demographic patterns, including land allocation, institutions design and government distrust, in addition to the typical investments in both physical infrastructure and hydrological information systems. The leadership role of the government, acting as a top-down trigger, is another essential element in Suriname.

Comparison of NDVI fields obtained from different remote sensors

Satellite image data have become an important source of information for monitoring vegetation and mapping land cover at several scales. Beside this, the distribution and phenology of vegetation is largely associated with climate, terrain characteristics and human activity. Various vegetation indices have been developed for qualitative and quantitative assessment of vegetation using remote spectral measurements. In particular, sensors with spectral bands in the red (RED) and near-infrared (NIR) lend themselves well to vegetation monitoring and based on them [(NIR - RED) / (NIR + RED)] Normalized Difference Vegetation Index (NDVI) has been widespread used. Given that the characteristics of spectral bands in RED and NIR vary distinctly from sensor to sensor, NDVI values based on data from different instruments will not be directly comparable. The spatial resolution also varies significantly between sensors, as well as within a given scene in the case of wide-angle and oblique sensors. As a result, NDVI values will vary according to combinations of the heterogeneity and scale of terrestrial surfaces and pixel footprint sizes. Therefore, the question arises as to the impact of differences in spectral and spatial resolutions on vegetation indices like the NDVI and their interpretation as a drought index. During 2012 three locations (at Salamanca, Granada and Córdoba) were selected and a periodic pasture monitoring and botanic composition were achieved. Daily precipitation, temperature and monthly soil water content were measurement as well as fresh and dry pasture weight. At the same time, remote sensing images were capture by DEIMOS-1 and MODIS of the chosen places. DEIMOS-1 is based on the concept Microsat-100 from Surrey. It is conceived for obtaining Earth images with a good enough resolution to study the terrestrial vegetation cover (20x20 m), although with a great range of visual field (600 km) in order to obtain those images with high temporal resolution and at a reduced cost. By contranst, MODIS images present a much lower spatial resolution (500x500 m). The aim of this study is to establish a comparison between two different sensors in their NDVI values at different spatial resolutions. Acknowledgements.

Impact of new technologies and social networks on a secondary education theatre project

This paper describes the potential impact of social media and new technologies in secondary education. The case of study has been designed for the drama and theatre subject. A wide set of tools like social networks, blogs, internet, multimedia content, local press and other promotional tools are promoted to increase students’ motivation. The experiment was developed at the highschool IES Al-Satt located in Algete in the Comunidad de Madrid. The students included in the theatre group present a low academic level, 80% of them had previously repeated at least one grade, half of them come from programs for students with learning difficulties and were at risk of social exclusion. This action is supported by higher and secondary education professors and teachers who look forward to implanting networked media technologies as new tools to improve the academic results and the degree of involvement of students. The results of the experiment have been excellent, based on satisfactory opinions obtained from a survey answered by students at the end of the course, and also revealed by the analytics taken from different social networks. This project is a pioneer in the introduction and usage of new technologies in secondary high-schools in Spain.

What Makes an Effective Abstract in Sport Science?

Writing an efficient abstract is always a difficult and significant work in academic writing. What kinds of abstracts are well reputed in sport science? To answer this question, 20 abstracts from top journals of sport science were analyzed in the current research. The number of words and rhetorical moves were studied to assess the structures of the abstracts. Meanwhile, the key clauses, citations, the use of first person pronoun, the adoption of abbreviations and acronyms, hedging and the main tense were included in the analysis of the writing skills. Results have show: (1) Almost all of the abstracts were non-structured, and the length varied a lot, but the average word count was about 210-220; (2) the use of writing skills, such as key clauses, citations and hedging differed depending on the preference of the journal where the abstract appeared, and the main tense was selected based on the context of the abstract. In most cases, abbreviations and acronyms were allowed to be used, while the first person pronoun was always avoided
