Nutritional intake and body composition of adolescent soccer player of two different levels of performance: a comparative study

Soccer participation worldwide is increasing and every club try to discover new talents. It is well know that there is an important correlation between body composition (BC) and talent detection (TD) and when coaches and selectors choose players, they tend to choose them with optimum BC.

Evolution of session RPE and fatigue during a long term nutritional intervention in one professional basketball player

Some evidence shows that the rate of perceived exertion of one session (RPE-S) and fatigue (Fat) of athletes can be decreased by the intake of carbohydrates (HCO) during exercise. However, it is well known that professional athletes do not meet nutritional recommendations (NR) but a long term nutritional intervention (NI) can improve their dietary intake (DI). What is not known is whether these long-term changes in DI can influence RPE-S and Fat of training. Our aim was to conduct a long term NI to adapt the DI of one professional basketball player to current NR and evaluate the influence of these changes on long-term RPE and Fat.

Nutritional intervention program in elite athletes: single case design research with one professional basketball player

The American College of Sports Medicine argues that sports performance is improved with optimal nutrition (ACSM position stand, MSSE 2009, Mar; 41(3):709-31). However, scientific evidence shows that professional athletes do not achieve nutritional recommendations (Farajian et al, IJSNEM 2004 Oct; 14(5):574-85; Shroeder et al EJSS 2004 Jun 4 (2):1; Nogueira & Da Costa, IJSNEM 2004; 14:684-697) Objectives: a) describe the nutritional practices of one professional basketball player b) carry out a long term nutritional intervention to adapt his diet to current recommendations.

The application of biomechanics to penalty corner drag-flick training: a case of Study

The penalty corner is one of the most important game situations in field hockey with one third of all goals resulting from this tactical situation. The aim of this study was to develop and apply a training method, based on previous studies, to improve the drag- flick skill on a young top-class field hockey player. A young top-class player exercised three times per week using specific drills over a four week period. A VICON optoelectronic system (Oxford Metrics, Oxford, UK) was employed to capture twenty drag-flicks, with six cameras sampling at 250 Hz, prior and after the training period. In order to analyze pre- and post-test differences a dependent t-test was carried out. Angular velocities and the kinematic sequence were similar to previous studies. The player improved (albeit not significantly) the angular velocity of the stick. The player increased front foot to the ball at T1 (p < 0.01) and the drag-flick distances. The range of motion from the front leg decreased from T1 to T6 after the training period (p < 0.01). The specific training sessions conducted with the player improved some features of this particular skill. This article shows how technical knowledge can help with the design of training programs and whether some drills are more effective than others.

Injury incidence in a Spanish sub-elite professional football team: A prospective study during four consecutive seasons

The aim of this study was to investigate the injury incidence and injury characteristics of a Spanish sub-elite professional football team during four consecutive seasons. A team was followed prospectively from the season 2003-2004 to 2006-2007 and individual player exposure and time loss injuries were recorded during all club training sessions and matches. A total of 313 time-loss injuries were recorded. The mean injury incidence was 10.9 injuries/1000 hours (5.2 injuries/1000 training hours and 44.1 injuries/1000 match hours). The injury incidence during competitive matches was higher (p < 0.001) than in friendly matches (55.8 vs. 22.6 injuries/1000 hours). The incidence of major injuries (>28 days absence) was 0.4 injuries/1000 hours. The thigh was the most commonly (35%) injured region and caused 29% of all competitive match absence. Muscle injuries in the four main groups of the lower limbs (hamstrings, adductors, quadriceps and calf muscles) caused 43% of competitive match unavailability. The results of this study show that the risk to sustain a major injury in the course of the season was low for sub-elite footballers in comparison to elite players. Thigh strains were the first cause of absence in competition due to injury.

Clean Coal Technologies Scenario and Evaluation of Present CO2 Dwindling Initiatives to Approach Zero Emission Power Stations By Coal Combustion. Deployment Situation and Evaluation Study

In the present uncertain global context of reaching an equal social stability and steady thriving economy, power demand expected to grow and global electricity generation could nearly double from 2005 to 2030. Fossil fuels will remain a significant contribution on this energy mix up to 2050, with an expected part of around 70% of global and ca. 60% of European electricity generation. Coal will remain a key player. Hence, a direct effect on the considered CO2 emissions business-as-usual scenario is expected, forecasting three times the present CO2 concentration values up to 1,200ppm by the end of this century. Kyoto protocol was the first approach to take global responsibility onto CO2 emissions monitoring and cap targets by 2012 with reference to 1990. Some of principal CO2emitters did not ratify the reduction targets. Although USA and China spur are taking its own actions and parallel reduction measures. More efficient combustion processes comprising less fuel consuming, a significant contribution from the electricity generation sector to a CO2 dwindling concentration levels, might not be sufficient. Carbon Capture and Storage (CCS) technologies have started to gain more importance from the beginning of the decade, with research and funds coming out to drive its come in useful. After first researching projects and initial scale testing, three principal capture processes came out available today with first figures showing up to 90% CO2 removal by its standard applications in coal fired power stations. Regarding last part of CO2 reduction chain, two options could be considered worthy, reusing (EOR & EGR) and storage. The study evaluates the state of the CO2 capture technology development, availability and investment cost of the different technologies, with few operation cost analysis possible at the time. Main findings and the abatement potential for coal applications are presented. DOE, NETL, MIT, European universities and research institutions, key technology enterprises and utilities, and key technology suppliers are the main sources of this study. A vision of the technology deployment is presented.

Integración MPlayer-OpenSVC en el procesador multinúcleo OMAP3530

La constante evolución de dispositivos portátiles multimedia que se ha producido en la última década ha provocado que hoy en día se disponga de una amplia variedad de dispositivos con capacidad para reproducir contenidos multimedia. En consecuencia, la reproducción de esos contenidos en dichos terminales lleva asociada disponer de procesadores que soporten una alta carga computacional, ya que las tareas de descodificación y presentación de video así lo requieren. Sin embargo, un procesador potente trabajando a elevadas frecuencias provoca un elevado consumo de la batería, y dado que se pretende trabajar con dispositivos portátiles, la vida útil de la batería se convierte en un asunto de especial importancia. La problemática que se plantea se ha convertido en una de las principales líneas de investigación del Grupo de Investigación GDEM (Grupo de Diseño Electrónico y Microelectrónico). En esta línea de trabajo, se persigue cómo optimizar el consumo de energía en terminales portables desde el punto de vista de la reducción de la calidad de experiencia del usuario a cambio de una mayor autonomía del terminal. Por tanto, para lograr esa reducción de la calidad de experiencia mencionada, se requiere un estándar de codificación de vídeo que así lo permita. El Grupo de Investigación GDEM cuenta con experiencia en el estándar de vídeo escalable H.264/SVC, el cual permite degradar la calidad de experiencia en función de las necesidades/características del dispositivo. Más concretamente, un video escalable contiene embebidas distintas versiones del video original que pueden ser descodificadas en diferentes resoluciones, tasas de cuadro y calidades (escalabilidades espacial, temporal y de calidad respectivamente), permitiendo una adaptación rápida y muy flexible. Seleccionado el estándar H.264/SVC para las tareas de vídeo, se propone trabajar con Mplayer, un reproductor de vídeos de código abierto (open source), al cual se le ha integrado un descodificador para vídeo escalable denominado OpenSVC. Por último, como dispositivo portable se trabajará con la plataforma de desarrollo BeagleBoard, un sistema embebido basado en el procesador OMAP3530 que permite modificar la frecuencia de reloj y la tensión de alimentación dinámicamente reduciendo de este modo el consumo del terminal. Este procesador a su vez contiene integrados un procesador de propósito general (ARM Cortex-A8) y un procesador digital de señal (DSP TMS320C64+TM). Debido a la alta carga computacional de la descodificación de vídeos escalables y la escasa optimización del ARM para procesamiento de datos, se propone llevar a cabo la ejecución de Mplayer en el ARM y encargar la tarea de descodificación al DSP, con la finalidad de reducir el consumo y por tanto aumentar la vida útil del sistema embebido sobre el cual se ejecutará la aplicación desarrollada. Una vez realizada esa integración, se llevará a cabo una caracterización del descodificador alojado en el DSP a través de una serie de medidas de rendimiento y se compararán los resultados con los obtenidos en el proceso de descodificación realizado únicamente en el ARM. ABSTRACT During the last years, the multimedia portable terminals have gradually evolved causing that nowadays a several range of devices with the ability of playing multimedia contents are easily available for everyone. Consequently, those multimedia terminals must have high-performance processors to play those contents because the coding and decoding tasks demand high computational load. However, a powerful processor performing to high frequencies implies higher battery consumption, and this issue has become one of the most important problems in the development cycle of a portable terminal. The power/energy consumption optimization on multimedia terminals has become in one the most significant work lines in the Electronic and Microelectronic Research Group of the Universidad Politécnica de Madrid. In particular, the group is researching how to reduce the user‟s Quality of Experience (QoE) quality in exchange for increased battery life. In order to reduce the Quality of Experience (QoE), a standard video coding that allows this operation is required. The H.264/SVC allows reducing the QoE according to the needs/characteristics of the terminal. Specifically, a scalable video contains different versions of original video embedded in an only one video stream, and each one of them can be decoded in different resolutions, frame rates and qualities (spatial, temporal and quality scalabilities respectively). Once the standard video coding is selected, a multimedia player with support for scalable video is needed. Mplayer has been proposed as a multimedia player, whose characteristics (open-source, enormous flexibility and scalable video decoder called OpenSVC) are the most suitable for the aims of this Master Thesis. Lastly, the embedded system BeagleBoard, based on the multi-core processor OMAP3530, will be the development platform used in this project. The multimedia terminal architecture is based on a commercial chip having a General Purpose Processor (GPP – ARM Cortex A8) and a Digital Signal Processor (DSP, TMS320C64+™). Moreover, the processor OMAP3530 has the ability to modify the operating frequency and the supply voltage in a dynamic way in order to reduce the power consumption of the embedded system. So, the main goal of this Master Thesis is the integration of the multimedia player, MPlayer, executed at the GPP, and scalable video decoder, OpenSVC, executed at the DSP in order to distribute the computational load associated with the scalable video decoding task and to reduce the power consumption of the terminal. Once the integration is accomplished, the performance of the OpenSVC decoder executed at the DSP will be measured using different combinations of scalability values. The obtained results will be compared with the scalable video decoding performed at the GPP in order to show the low optimization of this kind of architecture for decoding tasks in contrast to DSP architecture.

Commonalities between networking in multiplayer computer games and negotiation processes in a future multi-layered Air Traffic Management (ATM) system

First, this paper describes a future layered Air Traffic Management (ATM) system centred in the execution phase of flights. The layered ATM model is based on the work currently performed by SESAR [1] and takes into account the availability of accurate and updated flight information ?seen by all? across the European airspace. This shared information of each flight will be referred as Reference Business Trajectory (RBT). In the layered ATM system, exchanges of information will involve several actors (human or automatic), which will have varying time horizons, areas of responsibility and tasks. Second, the paper will identify the need to define the negotiation processes required to agree revisions to the RBT in the layered ATM system. Third, the final objective of the paper is to bring to the attention of researchers and engineers the communalities between multi-player games and Collaborative Decision Making processes (CDM) in a layered ATM system

Integración del descodificador OpenSVC en el DSP del OMAP3530

Hoy en día el uso de dispositivos portátiles multimedia es ya una realidad totalmente habitual. Además, estos dispositivos tienen una capacidad de cálculo y unos recursos gráficos y de memoria altos, tanto es así que por ejemplo en un móvil se pueden reproducir vídeos de muy alta calidad o tener capacidad para manejar entornos 3D. El precio del uso de estos recursos es un mayor consumo de batería que en ocasiones es demasiado alto y acortan en gran medida la vida de la carga útil de la batería. El Grupo de Diseño Electrónico y Microelectrónico de la Universidad Politécnica de Madrid ha abierto una línea de trabajo que busca la optimización del consumo de energía en este tipo de dispositivos, concretamente en el ámbito de la reproducción de vídeo. El enfoque para afrontar la solución del problema se basa en obtener un mayor rendimiento de la batería a costa de disminuir la experiencia multimedia del usuario. De esta manera, cuando la carga de la batería esté por debajo de un determinado umbral mientras el dispositivo esté reproduciendo un vídeo de alta calidad será el dispositivo quien se autoconfigure dinámicamente para consumir menos potencia en esta tarea, reduciendo la tasa de imágenes por segundo o la resolución del vídeo que se descodifica. Además de lo citado anteriormente se propone dividir la descodificación y la representación del vídeo en dos procesadores, uno de propósito general y otro para procesado digital de señal, con esto se consigue que tener la misma capacidad de cálculo que con un solo procesador pero a una frecuencia menor. Para materializar la propuesta se usará la tarjeta BeagleBoard basada en un procesador multinúcleo OMAP3530 de Texas Instrument que contiene dos núcleos: un ARM1 Cortex-A8 y un DSP2 de la familia C6000. Este procesador multinúcleo además permite modificar la frecuencia de reloj y la tensión de alimentación dinámicamente para conseguir reducir de este modo el consumo del terminal. Por otro lado, como reproductor de vídeos se utilizará una versión de MPlayer que integra un descodificador de vídeo escalable que permite elegir dinámicamente la resolución o las imágenes por segundo que se decodifican para posteriormente mostrarlas. Este reproductor se ejecutará en el núcleo ARM pero debido a la alta carga computacional de la descodificación de vídeos, y que el ARM no está optimizado para este tipo de procesado de datos, el reproductor debe encargar la tarea de la descodificación al DSP. El objetivo de este Proyecto Fin de Carrera consiste en que mientras el descodificador de vídeo está ejecutándose en el núcleo DSP y el Mplayer en el núcleo ARM del OMAP3530 se pueda elegir dinámicamente qué parte del vídeo se descodifica, es decir, seleccionar en tiempo real la calidad o capa del vídeo que se quiere mostrar. Haciendo esto, se podrá quitar carga computacional al núcleo ARM y asignársela al DSP el cuál puede procesarla a menor frecuencia para ahorrar batería. 1 ARM: Es una arquitectura de procesadores de propósito general basada en RISC (Reduced Instruction Set Computer). Es desarrollada por la empresa inglesa ARM holdings. 2 DSP: Procesador Digital de Señal (Digital Signal Processor). Es un sistema basado en procesador, el cual está orientado al cálculo matemático a altas velocidad. Generalmente poseen varias unidades aritmético-lógicas (ALUs) para conseguir realizar varias operaciones simultáneamente. SUMMARY. Nowadays, the use of multimedia devices is a well known reality. In addition, these devices have high graphics and calculus performance and a lot of memory as well. In instance, we can play high quality videos and 3D environments in a mobile phone. That kind of use may increase the device's power consumption and make shorter the battery duration. Electronic and Microelectronic Design Group of Technical University of Madrid has a research line which is looking for optimization of power consumption while these devices are playing videos. The solution of this trouble is based on taking more advantage of battery by decreasing multimedia user experience. On this way, when battery charge is under a threshold while device is playing a high quality video the device is going to configure itself dynamically in order to decrease its power consumption by decreasing frame per second rate, video resolution or increasing the noise in the decoded frame. It is proposed splitting decoding and representation tasks in two processors in order to have the same calculus capability with lower frecuency. The first one is specialized in digital signal processing and the other one is a general purpose processor. In order to materialize this proposal we will use a board called BeagleBoard which is based on a multicore processor called OMAP3530 from Texas Instrument. This processor includes two cores: ARM Cortex-A8 and a TMS320C64+ DSP core. Changing clock frequency and supply voltage is allowed by OMAP3530, we can decrease the power consumption on this way. On the other hand, MPlayer will be used as video player. It includes a scalable video decoder which let us changing dynamically the resolution or frames per second rate of the video in order to show it later. This player will be executed by ARM core but this is not optimized for this task, for that reason, DSP core will be used to decoding video. The target of this final career project is being able to choose which part of the video is decoded each moment while decoder is executed by DSP and Mplayer by ARM. It will be able to change in real time the video quality, resolution and frames per second that user want to show. On this way, reducing the computational charge within the processor will be possible.

Generación procedimental de contenidos en videojuegos

Este proyecto consiste en el desarrollo de un sistema completo de generación procedimental de misiones para videojuegos. Buscamos crear, mediante un encadenamiento de algoritmos y un modelado del juego y sus componentes, secuencias de acciones y eventos de juego encadenados entre sí de forma lógica. La realización de estas secuencias de acciones lleva progresivamente hacia un objetivo final. Estas secuencias se conocen en el mundo de los juegos como misiones. Las dos fases principales del proceso son la generación de una misión a partir de un estado de juego inicial y la búsqueda de una misión óptima utilizando ciertos criterios que pueden estar ligados a las propiedades del jugador, dando lugar a misiones adaptativas. El proyecto contempla el desarrollo íntegro del sistema, lo que incluye tanto el sistema de generación y búsqueda como un videojuego donde integrar el resto del sistema para completarlo. El resultado final es plenamente funcional y jugable. La base teórica del proyecto proviene de la simbiosis de dos artes: la generación procedimental de contenido y la narración interactiva. This project involves the development of a complete procedural game quest generation system. We seek to build, by linking a series of algorithms, game and game component models, sequences of logically chained game actions and events. The ordered accomplishment of these sequences lead progressively to the fulfillment of a final objective. These sequences are known as quests in the videogame world. The two main parts of the process are quest generation from an initial game state and optimal quest search. This last is achieved by using certain criteria that can defined by the player properties, thus giving birth to adaptive quests. In this project. The system is comprehensively developed, including the quest generation and optimal search, as well as a full videogame, in which the rest of the system will be embedded so as to complete it. The final result is fully functional and playable. The theoretical basis of the project comes from the symbiosis of two different arts: procedural content generation and interactive storytelling.

What if criminals optimize their choice? Optimal strategies to defend public goods

We investigate optimal strategies to defend valuable goods against the attacks of a thief. Given the value of the goods and the probability of success for the thief, we look for the strategy that assures the largest benefit to each player irrespective of the strategy of his opponent. Two complementary approaches are used: agent-based modeling and game theory. It is shown that the compromise between the value of the goods and the probability of success defines the mixed Nash equilibrium of the game, that is compared with the results of the agent-based simulations and discussed in terms of the system parameters.

Influencia de un nuevo marco jurídico en la competitividad del sistema portuario español

El sistema portuario español movió en el año 2013 aproximadamente 458,54 millones de toneladas, 13,8 millones de TEUs, con un total de 131.128 buques que accedieron a puerto para el conjunto de las 28 Autoridades Portuarias. Con el 62% de las exportaciones y el 86% de las importaciones realizadas por vía marítima, una rentabilidad del 2,34 %, muy cerca del objetivo del 2,5 % de rentabilidad media annual establecida legalmente, y una cifra de negocios aproximada de 1.028 millones de euros equivalentes al 1,1 % del PIB que genera un empleo directo e indirecto vinculado de 145.000 personas, concluimos que estamos hablando de un sector estratégico para la economía del país. Desde hace décadas, en muchos puertos del mundo se han venido desarrollando terminales “hub” o de concentración y distribución de cargas. Las navieras concentran entre este tipo de terminales sus líneas transoceánicas con buques de enormes dimensiones y capacidad de carga para producir los tránsitos de contenedores desde estas líneas a otras líneas llamadas “feeder”, con buques de menor tamaño que enlazan el “hub” con los puertos de su área marítima de influencia. La excepcional ubicación geoestratégica de España, con aproximadamente ocho mil kilómetros de costa, ha originado que los puertos españoles de mayor dimensión aspiren a incorporarse a esta red marítima internacional de contenedores y determina que en nuestro sistema portuario los movimientos de contenedores de tránsito tengan gran importancia. Sin embargo, la crisis económica ha tenido un efecto decisivo en el sector marítimo, determinando una lucha feroz entre todos los puertos, nacionales e internacionales, por captar este tipo de tráficos, lo que origina una búsqueda de las compañías navieras de puertos cada vez más eficientes en términos calidad/coste del servicio. La entrada en vigor del Texto Refundido de la Ley de Puertos y la piedra angular de su reforma, la Ley 33/2010, plantea como objetivo principal la mejora de la competitividad del sistema portuario español y liderar su recuperación, ofreciendo unas condiciones de entorno favorables a los puertos españoles que acaben por incentivar la captación de tráficos e inversión privada a través de una oferta de servicios e infraestructura de calidad y a precios competitivos que consoliden su posición dentro del tráfico marítimo mundial. Surge, por tanto, la conveniencia de investigar la influencia de las medidas propuestas por dicha norma legal y las soluciones ofrecidas a las demandas de un sector considerado estratégico para la economía del país, y cuya resolución se considera imprescindible para consolidar su recuperación. Por eso, se han analizado los aspectos más importantes de la reforma mediante la realización de un resumen ejecutivo y se ha estudiado la influencia de las medidas que incorpora desde el punto de vista de tres factores, que previamente se han considerado como fundamentales para la recuperación del sistema portuario español, y que históricamente habían sido demandados por el mismo, como son, en primer lugar, un progresivo sistema de flexibilización tributaria que permitiera a los puertos españoles ganar en términos de competitividad respecto a otros modelos portuarios mucho más flexibles en materia tarifaria, en segundo lugar, una necesaria liberalización del régimen de prestación de los servicios portuarios que posibilite el libre acceso a cualquier interesado en su prestación y, en último lugar, el progresivo abaratamiento de los costes inherentes a dichos servicios, fundamentalmente la manipulación de mercancías. Con posterioridad se ha investigado el trámite parlamentario al que se ha sometido la ley, fruto del enorme consenso alcanzado entre las dos principales fuerzas políticas del país, que determinó que se presentaran más de 700 enmiendas al proyecto original, y en algunos casos, se ha prestado especial atención a determinadas enmiendas que se consideran, en opinión de este investigador, novedosas y aventuradas, razón por la cual quizás no fueron incorporadas definitivamente al texto legal. Y se han analizado las principales demandas y aportaciones extraídas de la Sesión Informativa sobre la tramitación del entonces proyecto de ley ofrecida por la Comisión de Fomento del Congreso de los Diputados a los principales representantes del sector, comunidad portuaria, universidad y sindicatos. Siendo conscientes de la incidencia que tiene el servicio portuario de manipulación de mercancías en el paso de la mercancía por el puerto, se ha hecho una referencia concreta al peculiar régimen jurídico y laboral del personal vinculado al servicio. Avanzamos que las características de la relación laboral especial, y su peculiar régimen jurídico, con una dualidad de relaciones laborales, tiene una influencia decisiva en la nómina del trabajador que se repercute en los usuarios del servicio, fundamentalmente el naviero y el operador de la terminal, que en definitiva, incide en la competitividad del puerto. Y se ha constatado el auge aperturista de numerosas legislaciones portuarias europeas, prestando especial atención al proyecto frustrado de liberalización de los servicios portuarios en la Unión Europea de la conocida como Directiva Loyola de Palacio del año 2003 y al Libro Blanco de Transportes del año 2011. Así como a las deficiencias advertidas por el Dictamen de la Comisión Europea de fecha 27/09/2012 en relación al régimen jurídico del servicio portuario de manipulación de mercancías, que lo considera disconforme y contrario con las normas de libertad de establecimiento en Europa y que amenaza con una previsible reforma unilateral de la legislación portuaria española, a instancias europeas. Bajo este planteamiento, se ha procedido a analizar el marco de prestación de dichos servicios desde el punto de vista de la propia comunidad portuaria. Inicialmente, a través de un estudio de fuerzas de la competitividad del sector de los servicios portuarios en el sistema portuario español que nos permitirá trazar un mapa estratégico del mismo a través del “Modelo de las Cinco Fuerzas de Porter” concluyendo, que el poder de los prestadores de servicios portuarios como proveedores de los mismos, fundamentalmente en la manipulación de mercancías, es máximo, con un único colectivo, los estibadores portuarios, que al amparo de la normativa legal vigente tienen la exclusividad de su prestación. Dichas circunstancias restan competitividad al sistema frente a alternativas portuarias más flexibles y desincentivan la inversión privada. Y, en segundo lugar, mediante un proceso participativo en distintas encuestas sobre el modelo legislativo y sobre el marco formativo del sector con los propios agentes afectados dentro de la comunidad portuaria, desde la triple perspectiva de la vertiente pública que representan las Autoridades Portuarias, como gestores de las infraestructuras, la vertiente privada que representan los usuarios y prestadores de servicios, como principal cliente del puerto y desde el punto de vista de la propia mano de obra portuaria materializada en la representación sindical de dichos trabajadores. Los resultados nos permitirán concluir, respectivamente, la incidencia del servicio portuario mercancía por el puerto, por representar más de la mitad de los costes. Así como la aspiración de los trabajadores adscritos a dicho servicio de consolidar un título formativo que unifique y potencie su capacitación profesional, circunstancia esta última, también demandada por toda comunidad portuaria. Analizadas las conclusiones extraídas en cada una de las líneas de investigación se han detectado una serie de ineficiencias dentro del mismo que dicho marco regulador no ha sabido resolver, por lo que se ha considerado la conveniencia de formular, como herramienta de ayuda a gestores del sistema portuario español, una relación de medidas que, en opinión de este investigador, se consideran necesarias para mejorar el régimen de prestación de los servicios portuarios y se ha propuesto un borrador de modificación del actual Texto Refundido que pueda servir de base para materializar una futura reforma legal. Las conclusiones obtenidas en la investigación deben sentar las bases de una profunda reflexión sobre la necesidad de encaminar, como alternativa a una previsible modificación a instancias europeas, una reforma legal que decididamente apueste por la competitividad del sistema portuario español desde el punto de vista de la liberalización de servicios, el abaratamiento de los costes de la estiba y la necesaria profesionalización de los trabajadores adscritos al servicio portuario de manipulación de mercancías. During 2013 the Spanish Port System moved nearly 458,54 million tons of freight, 13,8 million TEUs, involving a total of 131.128 ships for the 28 existing Port Authorities. With 62% of exports and 86% of imports made through sea transportation, a 2,34% profit, close to the 2,5% average annual profit goal legally established, revenues of 1.028 million € equivalent to a 1.1% of Spain’s GDP and a figure of 145.000 people a directly or indirectly employed we can conclude that maritime industry is undoubtedly one of the strategic and key sectors for the country’s economy. Since several decades many ports in the world have been increasingly developing “Hub” terminals, those which concentrate and distribute freight. Shipping companies place among these type of terminals their transoceanic sea liners along with huge dimension & capacity ships to make the container transit from these liners to other called “feeder” which are smaller freight ships that connect the “hub” with the ports within its maritime area of influence. Spain’s exceptional geostrategic location with over 8.000 km of coastline has originated that those big dimension Spanish ports aspire to become a part of a container international maritime network which also determines that transit container move is key within our port system. Nevertheless the economic crisis has had a decisive impact on the maritime sector originating a fierce battle between all ports, national and international ones, all of them fight against each other to catch this type of maritime traffic which triggers an ongoing shipping companies search in cost/service quality efficient ports. The cornerstone of the Restated Text of Port Law is Law 33/2010, which lays out as main goal the Spanish Port System competitiveness improvement and lead its recovery offering favorable environment conditions to Spanish ports which help encourage maritime traffic attraction and private investment through a wide offer of services, quality of infrastructure and competitive prices which can consolidate its positioning within the world’s maritime traffic. It is therefore key to investigate the influence of the measures proposed by the above mentioned law and also the solutions offered to the demands of a sector which is considered strategic for the country’s economy and which solution is essential to consolidate the recovery. It is because of this that the most important aspects of the reform have been analyzed through the making of an executive summary and it has also been studied the influence of the measures it includes from the point of view of three factors which have previously been considered as key for the Spanish port system recovery. The system has historically demanded a progressive tax flexibility, which would permit Spanish ports be more competitive compared to other port models much more flexible in rates, a necessary liberalization of the port service provision regime and last but not least, to cut the price of costs related to those services, mainly freight handling. Following this, the parliamentary process of the law has also been studied as a consequence of the vast consensus reached by the main political forces in the country which clearly determined that more than 700 amendments to the original project were presented. In some cases the focus has been on amendments which are adventurous and new, reason why they were finally not included to the final legal text. Being well aware of the importance that freight handling procedure has, I have made a specific reference to the legal and working framework of those employees related to this service. We conclude that the special working relationship, its different legal regime, along with the working relationship dualism has a big impact and decisive influence over the worker’s salary which also affects service users, mainly shipowners and terminal operators, having a bad effect on the port’s competitiveness. The above confirms the new opening trend of main European port laws with special attention to the frustrated European Union port services liberalization project, also known as Directive Loyola de Palacio (2003) and the White Paper on Transports (2011). It is important to highlight that the European Commission has also observed several deficiencies with regard to the freight handling port service Law Regime being in disagreement with it, considering it is against the free establishment rules in Europe. The Commission is likely to present a unilateral reform to the Spanish Port Law. Under this approach the service provision framework is being analyzed from the Port Community point of view. Initially the analysis will focus on the study of the competition forces within the port services industry in Spain, this will allow us to draw up an strategic map through “Porter’s Five Forces Model” concluding that the power of port services providers as freight handlers is maximum, with an only collective, stevedores, which has the exclusivity for their services. All these circumstances not only decrease the system’s competitiveness versus other more flexible but also restrain private investments. Secondly, through a participating procedure in different surveys about the legislative model and about the training framework with the affected agents within the port community, there is a triple perspective: Public point of view represented by Port Authorities as infrastructure managers, Private point of view represented by users and service suppliers as main Port’s customer and finally, port workforce, represented by union leaders. Results will let us conclude that freight handling service is the most critical port service and represents more than half of the costs. This service related workers aspire to obtain a training certificate that unifies and boosts their professional role which is also chased by the entire port community. Once conclusions have been analyzed for all research lines, several deficiencies have been found and the regulatory framework hasn’t yet been able to solve them, it has therefore been a series of necessary measures that help improve the port services provision regime. A new proposal to the Restated Law Text has been drafted as the first step to embrace a future legal reform. Conclusions obtained on the research should set the new basis of a deep reflection about the need to bent on a new legal reform which firmly bets on Spanish port system competitiveness from three key points of view, service liberalization, ship load cost reduction and professionalization of freight handling related workers.
