Deporte e igualdad: las voces de las deportistas de élite

El objetivo de esta investigación ha sido analizar y valorar las percepciones de las deportistas de élite ante su insuficiente presencia en el deporte. La metodología utilizada permite examinar e interpretar los pensamientos y creencias de una cohorte de deportistas de alto rendimiento. El instrumento utilizado para el tratamiento de los datos ha sido el programa informático AQUAD 7. En este estudio se abordan diferentes modalidades de relación de las participantes (el balonmano como deporte colectivo, el atletismo como individual y la lucha judo como una competición entre dos individuos). Los resultados muestran que las deportistas perciben situaciones de discriminación de género y ausencias de igualdad de oportunidades en su desarrollo profesional. Las conclusiones de este estudio aconsejan proponer un cambio en las políticas tendentes a la equiparación efectiva en la carrera deportiva de las mujeres.

QUIC tramite udp: un’indagine sul protocollo che intende velocizzare il web

In questo documento ho analizzato lo scenario della passata e dell’odierna Internet, dal classico protocollo HTTP, al protocollo sperimentale QUIC, argomento di questa tesi. In primis ho analizzato gli attuali protocolli utilizzati nella rete e ricercato i motivi che hanno portato a crearne di nuovi, successivamente ho effettuato un analisi teorica del protocollo affidandomi ai documenti forniti dall'IETF, poi in un capitolo a sé ho descritto l'handshake crittografato tipico di questo protocollo ed infine nell'ultimo capitolo ho mostrato graficamente e praticamente come lavora il protocollo in una reale implementazione. Dopo aver completato questa tesi, mi sono potuto rendere conto di quanto sia necessario un cambio di rotta verso protocolli di rete più veloci, sicuri ed affidabili. I classici protocolli oramai non sono più sufficienti a soddisfare le migliaia di richieste di connessione e presentano, come si vedrà, delle lacune a cui bisogna porre rimedio. Gran parte della popolazione mondiale ha accesso al web,ed è uno strumento ormai alla portata di tutti e non più privilegio di pochi e ci si augura per il bene della rete Internet che tale protocollo o protocolli simili possano prendere presto piede per una migliore esperienza di navigazione a livello globale. Probabilmente saranno necessari molti anni, ma l’idea che già si pensi ad un futuro non tanto prossimo fa ben sperare su quello che ci aspetta. Nella lettura di questa tesi si vedrà come queste ultime affermazioni possano diventare realtà.

High-speed UDP Data Transmission with Multithreading and Automatic Resource Allocation

In this paper a utilization of the high data-rates channels by threading of sending and receiving is studied. As a communication technology evolves the higher speeds are used more and more in various applications. But generating traffic with Gbps data-rates also brings some complications. Especially if UDP protocol is used and it is necessary to avoid packet fragmentation, for example for high-speed reliable transport protocols based on UDP. For such situation the Ethernet network packet size has to correspond to standard 1500 bytes MTU[1], which is widely used in the Internet. System may not has enough capacity to send messages with necessary rate in a single-threaded mode. A possible solution is to use more threads. It can be efficient on widespread multicore systems. Also the fact that in real network non-constant data flow can be expected brings another object of study –- an automatic adaptation to the traffic which is changing during runtime. Cases investigated in this paper include adjusting number of threads to a given speed and keeping speed on a given rate when CPU gets heavily loaded by other processes while sending data.

HYBRID TCP/UDP video transport for H.264/AVC content delivery in burst loss networks

In this paper we propose a hybrid TCP/UDP transport, specifically for H.264/AVC encoded video, as a compromise between the delay-prone TCP and the loss-prone UDP. When implementing the hybrid approach, we argue that the playback at the receiver often need not be 100% perfect, provided that a certain level of quality is assured. Reliable TCP is used to transmit and guarantee delivery of the most important packets. This allows use of additional features in the H.264/AVC standard which simultaneously provide an enhanced playback quality, in addition to a reduction in throughput. These benefits are demonstrated through experimental results using a test-bed to emulate the hybrid proposal. We compare the proposed system with other protection methods, such as FEC, and in one case show that for the same bandwidth overhead, FEC is unable to match the performance of the hybrid system in terms of playback quality. Furthermore, we measure the delay associated with our approach, and examine its potential for use as an alternative to the conventional methods of transporting video by either TCP or UDP alone. © 2011 IEEE.

Altamira: hegemonía de élite y valor social en conflicto

El conflicto puede generarse cuando el equilibrio de poder entre las partes interesadas se desplaza, empoderando a unos y desempoderando a otros (McKercher et al. 2005). El Patrimonio, entendido como una valoración social incorporada a la realidad (Barreiro en prensa)1, forma un entramado ideal para convertirse en un inductor de conflictos, pues incluye la percepción de diferentes grupos, o individuos, con diferentes posiciones de poder en torno a los procesos de su gestión y su impacto. En 2012 y tras diez años de cierre preventivo de la Cueva de Altamira, se aprobó el Programa de Investigación para la Conservación Preventiva y Régimen de Acceso de la Cueva de Altamira, generando un activo debate en torno a la dicotomía cierreapertura. Con el objeto de profundizar en la caracterización de Altamira como enclave patrimonial, el Programa incorporó un estudio de Valor Social, cuyos resultados deberían servir, como los de los restantes proyectos del Programa, para optimizar las condiciones de gestión del sitio. Como parte del equipo de trabajo, a través de la presente comunicación, pretendemos analizar Altamira como espacio de conflicto durante el proceso de ejecución del Programa, convirtiéndonos a su vez en actores integrantes de dicho conflicto. Con la pretensión de obtener una idea global e integrada de Altamira, implementamos diferentes técnicas cualitativas y cuantitativas de investigación, a través de una aproximación interdisciplinar. Desde técnicas antropológicas y sociológicas, identificamos una variedad significativa de actores sociales(comunidad local, visitantes, personal del museo, especialistas en conservación, actores políticos, investigadores, empresarios, etc.) de diversos ámbitos territoriales (municipal, autonómico y estatal) que encarnaban las aristas de un conflicto poliédrico. Nuestro fin era analizar las distintas posiciones de poder desde las que los actores conformaban sus valoraciones sobre Altamira. Entre los múltiples resultados del estudio destacamos una normalización de la importancia del “valor” de Altamira en relación a otros espacios patrimoniales; una instrumentalización de dicho espacio desde la política para potenciar el valor económico de la zona; y una idealización del papel de los expertos en Patrimonio para decidir sobre la apertura-cierre de Altamira.

R-script modified VS-Lite model

Drought is a key factor affecting forest ecosystem processes at different spatio-temporal scales. For accurately modeling tree functioning ? and thus for producing reliable simulations of forest dynamics ? the consideration of the variability in the timing and extent of drought effects on tree growth is essential, particularly in strongly seasonal climates such as in the Mediterranean area. Yet, most dynamic vegetation models (DVMs) do not include this intra-annual variability of drought effects on tree growth. We present a novel approach for linking tree-ring data to drought simulations in DVMs. A modified forward model of tree-ring width (VS-Lite) was used to estimate seasonal- and site-specific growth responses to drought of Scots pine (Pinus sylvestris L.), which were subsequently implemented in the DVM ForClim. Ring-width data from sixteen sites along a moisture gradient from Central Spain to the Swiss Alps, including the dry inner Alpine valleys, were used to calibrate the forward ring-width model, and inventory data from managed Scots pine stands were used to evaluate ForClim performance. The modified VS-Lite accurately estimated the year-to-year variability in ring-width indices and produced realistic intra-annual growth responses to soil drought, showing a stronger relationship between growth and drought in spring than in the other seasons and thus capturing the strategy of Scots pine to cope with drought. The ForClim version including seasonal variability in growth responses to drought showed improved predictions of stand basal area and stem number, indicating the need to consider intra-annual differences in climate-growth relationships in DVMs when simulating forest dynamics. Forward modeling of ring-width growth may be a powerful tool to calibrate growth functions in DVMs that aim to simulate forest properties in across multiple environments at large spatial scales.
