Chapter 2 by Luca Di Blasi (...) gives us an insight into the history of nihilism, specifically by exposing a continuity (or else a cycle or repetition) between the earliest debates on the subject in the turn of the nineteenth century and latest ones in the turn of the twenty-first Di Blasi emphasizes the fact that the struggle between philosophy and religion, reason and faith, was a pertinent motif in Jacobi’s critique of Fichte’s philosophy and in Hegel’s response to this critique. A similar problematic, and similar dynamic, recurs two centuries later, where debates around the concept of nihilism among thinkers like Vattimo, Derrida, Habermas, and Žižek again revolve around the relation between religion, science, secularism, and “post-secularism.” Beginning with Hegel, Di Blasi’s chapter ends with a focus on Žižek as a “neo-Hegelian” showing how, in attacking his contemporaries, Žižek mirrors and revives Hegel’s approach in his critique of Jacobi and Fichte. Suggestively, Žižek informs us that now “the circle is closed” and that “to be a Hegelian today does not mean to assume the superfluous burden of some metaphysical past, but to regain the ability to begin from the beginning...”

Glacier fluctuations are a key indicator of changing climate. Their reconstruction beyond historical times unravels glacier variability and its forcing factors on long time scales, which can considerably improve our understanding of the climate–glacier relationship. Here, we present a 2250-year-long reconstruction of particle-mass accumulation rates recorded in the lacustrine sediments of Lake Trüebsee (Central Swiss Alps) that are directly related to glacier extent, thus reflecting a continuous record of fluctuations of the upstream-located Titlis Glacier. Mass accumulation rate values show strong centennial to multi-centennial fluctuations and reveal 12 well-pronounced periods of enhanced values corresponding to times of maximum extent of the neighboring Lower Grindelwald Glacier. This result supports previous studies of proglacial lake sediments that documented high mass accumulation rate values during glacier advances. The strong variability in the Lake Trüebsee mass accumulation rate record thus represents a highly sensitive paleoclimatic archive, which mirrors rapid and pronounced feedbacks of Titlis Glacier to climatic changes over the past 2250years. The comparison of our data with independent paleo-temperature reconstructions from tree rings suggests that variations in mean summer temperature were the primary driving factor of fluctuations of Titlis Glacier. Also, advances of Titlis Glacier occurred during the grand solar minima (Dalton, Maunder, Spörer, Wolf) of the last millennium. This relation of glacier extent with summer temperature reveals strong evidence that the mass balance of this Alpine glacier is primarily controlled by the intensity of glacier melting during summer.

In the wake of the financial crisis, budgetary discipline has taken centre stage in politics. More than ever a country's budget mirrors the true policy preferences of the legislative majority beyond all political discourse and cheap talk. The paper sheds light on mandate fulfilment in the field of public spending and fiscal policy in general. Based on previous work on pledge fulfilment in Switzerland the paper compares publicised pre-electoral statements of MPs on public spending and the development of the public finances with their post-electoral legislative behaviour during budget debates and votes. The findings of the paper confirm the results of the aforementioned earlier studies and point to the potential of budgetary statements for future mandate fulfilment research.

BACKGROUND: Central and peripheral vision is needed for object detection. Previous research has shown that visual target detection is affected by age. In addition, light conditions also influence visual exploration. The aim of the study was to investigate the effects of age and different light conditions on visual exploration behavior and on driving performance during simulated driving. METHODS: A fixed-base simulator with 180 degree field of view was used to simulate a motorway route under daylight and night conditions to test 29 young subjects (25-40 years) and 27 older subjects (65-78 years). Drivers' eye fixations were analyzed and assigned to regions of interests (ROI) such as street, road signs, car ahead, environment, rear view mirror, side mirror left, side mirror right, incoming car, parked car, road repair. In addition, lane-keeping and driving speed were analyzed as a measure of driving performance. RESULTS: Older drivers had longer fixations on the task relevant ROI, but had a lower frequency of checking mirrors when compared to younger drivers. In both age groups, night driving led to a less fixations on the mirror. At the performance level, older drivers showed more variation in driving speed and lane-keeping behavior, which was especially prominent at night. In younger drivers, night driving had no impact on driving speed or lane-keeping behavior. CONCLUSIONS: Older drivers' visual exploration behavior are more fixed on the task relevant ROI, especially at night, when driving performance becomes more heterogeneous than in younger drivers.

In contact shots, the muzzle imprint is an informative finding associated with the entrance wound. It typically mirrors the constructional components being in line with the muzzle or just behind. Under special conditions, other patterned skin marks located near a gunshot entrance wound may give the impression to be part of the muzzle imprint. A potential mechanism causing a patterned pressure abrasion in close proximity to the bullet entrance site is demonstrated on the basis of a suicidal shot to the temple. The skin lesion in question appeared as a ring-shaped excoriation with a diameter corresponding to that of the cartridge case. Two hypotheses concerning the causative mechanism were investigated by test shots: - After being ejected, the cartridge case ricocheted inside a confined space (car cabin in the particular case) and secondarily hit the skin near the gunshot entrance wound. - The ejection of the cartridge case failed so that the case became stuck in the ejection port and its mouth contacted the skin when the body collapsed after being hit.

Paul Ricœur describes selfhood as the product of a communal narrative. Communal narratives structured as symbolic myths provide a narrative identity and an ethic of selfhood. The psychologist Jerome Bruner, for instance, places the source of such a narrative identity in the family, where ‘canonical stories’ are formed. ‘Home’ becomes a mode of discourse, a way of recognizing ourselves in the narratives given to us by others. This paper will draw on these concepts of narrative identity in order to investigate the problems to selfhood which face the character of The Doctor in the BBC series Doctor Who. I will identify The Doctor as a character who acts within a self-constructed narrative vacuum, reading the character by contrasting two types of personal myth-making, one ‘real’, as in a lived narrative, and one ‘counterfeit’; a conjured myth to replace and obscure the lived self. The paper will pay particular attention to the twenty-first century reincarnations of Doctor Who. I will argue that the writing of Russell T. Davis and later Steven Moffat in particular directly address this tension of myth and selfhood, as The Doctor struggles between his self-imposed role as a modern Prometheus and the insistent haunting and return of his own story. In these incarnations, his companions become mirrors to The Doctor, bringing with them their own narrative and ethical identities. In turn, it is through his companions that The Doctor is able to build his own lived narrative of sorts, which challenges his self-created ‘mythology’. In contrast to the weeping angels, whose horrific agency manifests only when not apprehended, the Doctor’s story continues to become more real the more he is ‘perceived’, both by the human race and by the viewer.

This paper considers ocean fisheries as complex adaptive systems and addresses the question of how human institutions might be best matched to their structure and function. Ocean ecosystems operate at multiple scales, but the management of fisheries tends to be aimed at a single species considered at a single broad scale. The paper argues that this mismatch of ecological and management scale makes it difficult to address the fine-scale aspects of ocean ecosystems, and leads to fishing rights and strategies that tend to erode the underlying structure of populations and the system itself. A successful transition to ecosystem-based management will require institutions better able to economize on the acquisition of feedback about the impact of human activities. This is likely to be achieved by multiscale institutions whose organization mirrors the spatial organization of the ecosystem and whose communications occur through a polycentric network. Better feedback will allow the exploration of fine-scale science and the employment of fine-scale fishing restraints, better adapted to the behavior of fish and habitat. The scale and scope of individual fishing rights also needs to be congruent with the spatial structure of the ecosystem. Place-based rights can be expected to create a longer private planning horizon as well as stronger incentives for the private and public acquisition of system relevant knowledge.

La singular trayectoria de Julio Cortázar traza una parábola que parte de su inicial situación como escritor mentalmente colonizado (Jauretche) para arribar a una toma de conciencia político-histórica que lo impele a denunciar el genocidio cultural perpetrado por el imperialismo norteamericano y a defender las revoluciones socialistas de su tiempo. En este sentido, nuestro trabajo pretende indagar en la conversión de su antropología poética en poética histórica, entendiendo que los problemas metafísicos que plantea la primera desde una dimensión estrictamente literaria se abren al campo geopolítico a través de la confluencia entre política de la literatura y política del escritor (Rancière). Seleccionamos para ello un amplio corpus de textos y analizamos la evolución de la poética cortazariana en relación a la configuración de los sujetos populares. Observamos que éstos se muestran inicialmente como una alteridad radical (Baudrillard) respecto del yo enunciador, para constituir posteriormente la encarnación de un paradigma cultural que posibilita una existencia auténtica a través de la solidaridad y el encuentro con los otros (García Canclini). Finalmente, nos detendremos en el “sentimiento solar" y en los “hombres-puente" como símbolos de un Cortázar maduro y esperanzado que propone el equilibrio entre polaridades como condición necesaria para la verdadera revolución.

The variability in size and shape of shells of the polar planktonic foraminifer Neogloboquadrina pachyderma have been quantified in 33 recent surface sediment samples throughout the northern Atlantic Ocean and correlated with the properties of the ambient surface waters. The aim of the study was to determine whether any of the morphological features could be used to reconstruct sea surface properties in the polar realm of the North Atlantic, where most paleotemperature proxies appear to fail. The analyses revealed that shell morphology is only weakly controlled by habitat properties, whereas shell size showed a strong correlation with sea surface temperature. The regression of mean shell size on sea surface temperature revealed the presence of two trends among the sinistrally coiled shells: a continuous increase in shell size with decreasing SST in sediments deposited under polar water masses and a continuous increase in shell size with increasing SST in samples from transitional waters. The second trend mirrors the trend observed for dextrally coiled shells, which are frequent in the same samples and signal the presence of N. incompta. The identical mean shell size trends among the sinistral and dextral specimens in the temperate samples confirms the results of earlier genetic studies which indicated the existence of a small but distinct proportion of opposite coiling in N. incompta, to which the sinistral shells in the temperate samples could be attributed. The linear correlation between mean shell size and sea surface temperature in the polar domain (summer SST < 9 °C) has been used to develop an empirical formula for the reconstruction of past sea surface temperatures from shell sizes in fossil samples. The standard error of the residuals of the linear regression is 2.36 °C (1 sigma), which implies a much larger error than for most paleothermometers, but enough precision to allow resolution between results by individual paleothermometers in the polar domain. The resulting regression model has been applied on two sediment cores spanning the interval from the Last Glacial Maximum (LGM) to the present day. The results from core PS1906-1 are consistent with ice-free conditions during the LGM in the Norwegian Sea. The SST estimates for the LGM inferred from N. pachyderma shell size are similar or slightly higher than those for the latest Holocene. The results do not indicate anomalously high SST during the glacial and the LGM reconstructions thus appear more consistent with the results from foraminiferal transfer functions and geochemical proxies. Both sediment cores show the highest reconstructed SST during the early Holocene insolation optimum.

La tesis de maestría 'Recuerdos, espejos y lugares en el teatro comunitario argentino contemporáneo. Memoria colectiva, identidades, y espacio público en las prácticas del Grupo de Teatro Popular de Sansinena [2010-2012]', indaga en las operaciones de memoria, la constitución de identidades y los procesos construcción/ reapropiación del espacio público, que tienen lugar en las prácticas de este grupo de teatro. Dentro del proceso de creación colectiva de la obra, se reconstruyen interpretaciones del pasado compartido, tensiones que dan cuenta de las lógicas que estructuran la selección de los hechos a contar, valores y representaciones que visibilizan un modo de percibir/ construir las identidades. El Grupo de Teatro Popular de Sansinena, la primera organización social que existe en el pueblo, configura un experiencia colectiva novedosa, que instaura nuevas lógicas de sociabilidad, genera vínculos con el 'afuera' y reivindica la bandera de resistencia y el reclamo de visibilización a través de la práctica cultural. Dentro de las dinámicas relacionales que atraviesan el grupo, observamos ciertas tendencias jerárquicas en los vínculos entre la directora y los vecinos que conforman el grupo 'lo que se percibe como una dificultad a superar- estructuradas en el fuerte liderazgo construido por la directora. Una Legitimidad configurada sobre los saberes reconocidos, virtudes heredadas y capacidades comprobadas en la práctica, que se perciben en los testimonios de los vecinos-actores. La conformación del Grupo de Teatro Comunitario de Rivadavia -compuesto por doscientos vecinos de seis pueblos del Partido de Rivadavia (incluido Sansinena)-, da cuenta de los alcances de este fenómeno, que deberá seguir estudiándose desde diversas perspectivas, a fin de visibilizar la relevancia que esta práctica cultural adquiere, tanto a nivel local como nacional

La Orientación Vocacional en Dinamarca está bien organizada y es altamente profesional. Esto refleja una política orientadora centrada en el papel que la orientación juega como instrumento en el ejercicio de un leve control social. Con este telón de fondo, el dilema de la Orientación en Dinamarca reside en el delicado equilibrio existente entre la orientación considerada como una herramienta para el desarrollo personal, y como un instrumento de control social.
