To address growing concern over the effects of fisheries non-target catch on elasmobranchs worldwide, the accurate reporting of elasmobranch catch is essential. This requires data on a combination of measures, including reported landings, retained and discarded non-target catch, and post-discard survival. Identification of the factors influencing discard vs. retention is needed to improve catch estimates and to determine wasteful fishing practices. To do this we compared retention rates of elasmobranch non-target catch in a broad subset of fisheries throughout the world by taxon, fishing country, and gear. A regression tree and random forest analysis indicated that taxon was the most important determinant of retention in this dataset, but all three factors together explained 59% of the variance. Estimates of total elasmobranch removals were calculated by dividing the FAO global elasmobranch landings by average retention rates and suggest that total elasmobranch removals may exceed FAO reported landings by as much as 400%. This analysis is the first effort to directly characterize global drivers of discards for elasmobranch non-target catch. Our results highlight the importance of accurate quantification of retention and discard rates to improve assessments of the potential impacts of fisheries on these species.

La Ciberseguridad es un campo que cada día está más presente en nuestra vida con el avance de la tecnología. Gobiernos, militares, corporaciones, instituciones financieras, hospitales y otros negocios recogen, procesan y almacenan una gran cantidad de información confidencial en sus ordenadores y transmiten estos datos a través de redes a otros ordenadores. Con el creciente volumen y la sofisticación de los Ciberataques, se requiere una atención continua para proteger los negocios sensibles y la información personal así como salvaguardar la seguridad nacional. En el futuro casi todo va a ser informático por lo que con el avance de la tecnología nuevas amenazas aparecen, más peligrosas y sofisticadas. El enfoque de nuestro proyecto es demostrar que con unos pocos conocimientos de redes, seguridad, computación en la nube y unas pocas líneas de código se puede implementar una potente herramienta de ataque que puede poner en peligro la integridad y confidencialidad de los usuarios e instituciones.

En la primera parte del artículo se aborda el problema que ha de afrontar el estadista Antonio Maura al convertirse en el jefe del gobierno español, a finales de 1903 y consistente en concluir el proceso de negociación sobre Marruecos entablado con Francia desde 1901. Se resalta el carácter continuista del ideario colonial de Maura con respecto al del anterior líder conservador, Silvela, y la preponderancia de cuestiones como la seguridad nacional como motivadoras de dicho ideario. En la segunda parte, se explica la apelación del gobierno maurista a una ayuda por parte de Alemania, en función de movimientos previos de la diplomacia germana que se había interesado por controlar una parte del Marruecos español, o por conseguir compensaciones en Fernando Po. Finalmente se analiza el intento de Berlín de instrumentalizar al gobierno Maura en el curso de las conversaciones hispano-francesas sobre el Imperio jerifiano.

Este trabajo analiza el impacto que ha generado la crisis económica y financiera más reciente en las industrias cinematográficas de siete países miembros de la Unión Europea. Las conclusiones señalan que, en efecto, la crisis ha impactado negativamente en las industrias de España e Italia, y muy gravemente en la de Portugal, pero en el lado contrario, la del Reino Unido ha experimentado un crecimiento apreciable y las de Francia y Alemania también lo han hecho, aunque en menor medida. Y en segundo lugar, es muy notable la escasa colaboración alcanzada entre los agentes europeos.

The postwar development of the Intelligence Services in Japan has been based on two contrasting models: the centralized model of the USA and the collegiality of UK, neither of which has been fully developed. This has led to clashes of institutional competencies and poor anticipation of threats towards national security. This problem of opposing models has been partially overcome through two dimensions: externally through the cooperation with the US Intelligence Service under the Treaty of Mutual Cooperation and Security; and internally though the pre-eminence in the national sphere of the Department of Public Safety. However, the emergence of a new global communicative dimension requires that a communicative-viewing remodeling of this dual model is necessary due to the increasing capacity of the individual actors to determine the dynamics of international events. This article examines these challenges for the Intelligence Services of Japan and proposes a reform based on this new global communicative dimension.

After the triple disaster of 11 March 2011, Japan is at an energy crossroad. In the short and medium run it depends on fossil fuel imports to ensure its energy security, but the long term will be determined by the decisions taken at present. For Japan energy security is a national security challenge, as stated in its National Security Strategy. The article reviews the Japanese nuclear path, studies the factors shaping the Japanese electricity market and analyzes the current energy situation. Moreover, it also assesses the principles that have marked Japan’s energy policy and the two last Strategic Energy Plans -one prior to Fukushima and the other after it- before tackling the debate on the optimal future energy mix that Japan should adopt to meet its energy security trilemma, marked by its environmental commitment.

Class has always been at the heart of the television crime drama. Whether it is the post-war paternalism of Dixon of Dock Green (1955 – 1976), the harsh social realism of The Sweeney (1975-1978), or the almost mythical evocations of Britain in Heartbeat (1992 – 2010) and Midsomer Murders (1997- present), class and crime have always been seen as being inextricably linked. Since the 1990s, the British crime drama has been influenced by successive waves of cultural imports from, firstly, the US and then from Scandinavia. There is now a recognisable ‘genre’ for what we might think of as British TV Noir. Beginning with shows such as Cracker (1993 – 2006), Prime Suspect (1991 – 2006) and Messiah (2001) and continuing with dramas like Red Riding (2008), Southcliffe (2013) and Hinterland (2013 – present), the British TV Noir employs narratives and stylistic tropes that might usually be associated with the cinema of the 1940s. Although drawing influence from high profile shows such as Twin Peaks (1990 – 1991), Millennium (1996) and (latterly) The Wire (2002 – 2008), CSI (2000 – present) and The Killing (2007) these British Noir shows also articulate the nation’s shifting class system. As Susan Sydney-Smith has ably demonstrated, the crime drama is “historically contingent” (Sydney-Smith, 2002, p. 5) and shaped by the surrounding socio-political, as well aesthetic, context. To this end, this chapter traces the depiction of class in three key crime series – Prime Suspect, Red Riding and Southcliffe - and explores how social class, and more importantly, its changing face provides a constant background to the narratives and characterisations. These three texts were each produced at pivotal moments in Britain’s relationship to class – Prime Suspect was shown 6 months after Margaret Thatcher vacated office; Red Riding was produced in the midst of the global recession in 2008 and Southcliffe was made in the shadows of stringing welfare and immigration reforms. These texts span three successive political administrations and over two decades of social and political change. Understanding the relationship between criminal activity and class in these dramas however is far more complicated than simply reading the historical context through the text. Commensurate with its cinematic incarnation, TV Noir is both reflective and productive, employing visual and narrative tropes to manipulate, as well reflect, its audience’s moral and social positioning. The picture that emerges from an examination of class and the British TV Noir is one of suspicion and discontent. As Andrew Spicer suggests (with reference to British cinema) the Noir sensibility both depicts and critiques a society that it sees as being “class-ridden, racist and misogynist” (Spicer, 2002, p.202). This is certainly the case with the texts that are being examined here, as social positions and taxonomies are constantly being redefined and renegotiated.

En este artículo se discuten las posibles causas explicativas del estancamiento de la pobreza, tanto en la incidencia, intensidad y severidad, durante los últimos siete años (1994-2000), poniendo especial atención al efecto de la inmigración internacional, particularmente la procedente de Nicaragua. Para realizar el análisis se sigue la definición oficial de pobreza, como una situación de ingresos corrientes insuficientes, y se hace uso de las encuestas de hogares del Instituto Nacional de Estadística y Censos. Pese a que las encuestas tienen limitaciones para captar adecuadamente la inmigración internacional, particularmente la no regularizada, la información disponible sugiere que su contribución al estancamiento de la pobreza puede ser limitada hasta el presente. El aún reducido peso población, junto a una disminución en la incidencia de la pobreza entre los inmigrantes, apoya esta conclusión. No obstante, esta convergencia de la pobreza entre los inmigrantes y no inmigrantes, los primeros muestran un amplio dinamismo poblacional, una segregación geográfica, más no ocupacional, y un amplio, aunque discriminado, acceso a los servicios públicos en general y sociales en particular. Un crecimiento económico limitado y concentrado en pocas actividades con reducido impacto en los trabajadores menos calificados, junto a un menor capital humano en los nuevos contingentes de población activa, parecen ofrecer un mayor poder explicativo del fenómeno. Por el contrario, la desigualdad en la distribución de los ingresos parece tener un efecto neutro. De ser este el caso, un mayor y balanceado crecimiento económico, junto a una agresiva política social para revertir el deterioro del capital humano, surgen como las acciones prioritarias para reiniciar el descenso de la pobreza.
