"Fact versus Fiction – How paratextual information shapes our reading processes"

Our life is full of stories: some of them depict real-life events and were reported, e.g. in the daily news or in autobiographies, whereas other stories, as often presented to us in movies and novels, are fictional. However, we have only little insights in the neurocognitive processes underlying the reading of factual as compared to fictional contents. We investigated the neurocognitive effects of reading short narratives, labeled to be either factual or fictional. Reading in a factual mode engaged an activation pattern suggesting an action-based reconstruction of the events depicted in a story. This process seems to be past-oriented and leads to shorter reaction times at the behavioral level. In contrast, the brain activation patterns corresponding to reading fiction seem to reflect a constructive simulation of what might have happened. This is in line with studies on imagination of possible past or future events.

Reconstruction of a flash flood with large wood transport and its influence on hazard patterns in an ungauged mountain basin

The reconstruction of past flash floods in ungauged basins leads to a high level of uncertainty, which increases if other processes are involved such as the transport of large wood material. An important flash flood occurred in 1997 in Venero Claro (Central Spain), causing significant economic losses. The wood material clogged bridge sections, raising the water level upstream. The aim of this study was to reconstruct this event, analysing the influence of woody debris transport on the flood hazard pattern. Because the reach in question was affected by backwater effects due to bridge clogging, using only high water mark or palaeostage indicators may overestimate discharges, and so other methods are required to estimate peak flows. Therefore, the peak discharge was estimated (123 ± 18 m3 s–1) using indirect methods, but one-dimensional hydraulic simulation was also used to validate these indirect estimates through an iterative process (127 ± 33 m3 s–1) and reconstruct the bridge obstruction to obtain the blockage ratio during the 1997 event (~48%) and the bridge clogging curves. Rainfall–Runoff modelling with stochastic simulation of different rainfall field configurations also helped to confirm that a peak discharge greater than 150 m3 s–1 is very unlikely to occur and that the estimated discharge range is consistent with the estimated rainfall amount (233 ± 27 mm). It was observed that the backwater effect due to the obstruction (water level ~7 m) made the 1997 flood (~35-year return period) equivalent to the 50-year flood. This allowed the equivalent return period to be defined as the recurrence interval of an event of specified magnitude, which, where large woody debris is present, is equivalent in water depth and extent of flooded area to a more extreme event of greater magnitude. These results highlight the need to include obstruction phenomena in flood hazard analysis.

Characterisation of flash floods in small ungauged mountain basins of Central Spain using an integrated approach

One of the main problems of flood hazard assessment in ungauged or poorly gauged basins is the lack of runoff data. In an attempt to overcome this problem we have combined archival records, dendrogeomorphic time series and instrumental data (daily rainfall and discharge) from four ungauged and poorly gauged mountain basins in Central Spain with the aim of reconstructing and compiling information on 41 flash flood events since the end of the 19th century. Estimation of historical discharge and the incorporation of uncertainty for the at-site and regional flood frequency analysis were performed with an empirical rainfall–runoff assessment as well as stochastic and Bayesian Markov Chain Monte Carlo (MCMC) approaches. Results for each of the ungauged basins include flood frequency, severity, seasonality and triggers (synoptic meteorological situations). The reconstructed data series clearly demonstrates how uncertainty can be reduced by including historical information, but also points to the considerable influence of different approaches on quantile estimation. This uncertainty should be taken into account when these data are used for flood risk management.

Science & Fiction: Imagination und Realität des Weltraums

Der Kosmos ist seit Menschengedenken ein Gegenstand der forschenden Neugierde und der phantastischen Projektion. Wissenschaft und Kunst, science and fiction, Realität und Fiktion, sind sich nie so nah wie angesichts des Weltraums, jenes unerreichbaren Ganzen. Astronom / innen und Weltraumingenieur/innen beschäftigen space artists, und umgekehrt schöpfen Schriftsteller/innen und Filmemacher/innen aus den Entdeckungen der Physik und Weltraumtechnik. Der Leitgedanke der diesem Band zugrunde liegenden Ringvorlesung Science & ­Fiction: Imagination und Realität des Weltraums war, die Weltraumexploration im weitesten Sinne kulturgeschichtlich zu verstehen, um alle Wissenschaften in das Thema einzubeziehen. Es wurden daher sowohl Naturwissenschaftler/innen als auch ebenso viele Geisteswissenschaftler/innen eingeladen. Sie beleuchten in ihren Beiträgen die Geschichte der wissenschaftlichen, technischen und künstlerischen Visualisierungen des Weltraums und stellen Ergebnisse und Projekte der Weltraumforschung vor. Ein besonderes Interesse liegt dabei auf den vielfältigen Beziehungen zwischen den Bereichen der fiction – der Visualisierungen und Imaginationen des Weltraums – und der science – der Realitäten der naturwissenschaftlichen Erforschung des Weltraums.

Combining Wireless Sensor Networks and Machine Learning for Flash Flood Nowcasting

This paper addresses an investigation with machine learning (ML) classification techniques to assist in the problem of flash flood now casting. We have been attempting to build a Wireless Sensor Network (WSN) to collect measurements from a river located in an urban area. The machine learning classification methods were investigated with the aim of allowing flash flood now casting, which in turn allows the WSN to give alerts to the local population. We have evaluated several types of ML taking account of the different now casting stages (i.e. Number of future time steps to forecast). We have also evaluated different data representation to be used as input of the ML techniques. The results show that different data representation can lead to results significantly better for different stages of now casting.

Melodrama and Narrative Fiction: Towards a Typology

Recent research on melodrama has stressed its versatility and ubiquity by approaching it as a mode of expression rather than a theatrical genre. A variety of contexts in which melodrama is at work have been explored, but only little scholarly attention has been paid to the relationship between melodrama and novels, short stories and novellas. This article proposes a typology of melodrama in narrative prose fiction, examining four different categories: Melodrama and Sentimentalism, Depiction of Melodramatic Performances in Narrative Prose Fiction, Theatrical Antics and Aesthetics in Narrative Prose Fiction and Meta-Melodrama. Its aim is to clarify the ways in which melodrama, ever since its early days on the stages of late eighteenth-century Europe, has interacted with fictional prose narratives, thereby shaping the literary imagination in the Anglophone world.

Prometheus on Mars: Nineteenth-Century Science Fiction and the Language of Romanticism

The development of astrophysics in the nineteenth century drew mankind closer to the planets. For the first time, it was possible to give serious scientific consideration to the possibilities for life on other planets. The greatest leap, however, was in recognizing what was not known, and acknowledging the limits of human intuition. ‘Ideas,’ wrote Agnes M. Clerke, ‘have all at once become plastic’. As the scientific community tested the limits of scientific understanding, it became the role of science-fiction writers to imagine the universe beyond these limits. This paper will examine the ways in which nineteenth-century science fiction used the inheritance of the poetic language of Romanticism to reinstate the centrality of human being in the universe. I will explore the ways in which writers such as Edward Bulwer-Lytton (The Coming Race, 1871) and W. S. Lach-Szyrma (Aleriel, 1883) extended the Byronic hero to envisage extra-terrestrial utopias. The Hegelian systematic mythology described by Byron and Shelley had reimagined paradise and redemption on earth. Through science fiction, this mythology extended out towards the stars. A discourse on the possibilities of extra-terrestrial life became a Romantic discourse on the possibilities of being. The Byronic hero could now find a home not by escaping the shackles of religion, but as an angelic citizen of Venus or Mars. In this way, the paper will explore how science-fiction writers appropriated the language of Romantic poetry to build a bridge between the framework of scientific knowledge and the extent of human imagination.
