Editors' Introduction
No full textFriedrich Nietzsche’s intellectual autobiography Ecce Homo has always been a controversial book. Nietzsche prepared it for publication just before he became incurably insane in early 1889, but it was held back until after his death, and finally appeared only in 1908. For much of the first century of its reception, Ecce Homo met with a sceptical response and was viewed as merely a testament to its author’s incipient madness. This was hardly surprising, since he is deliberately outrageous with the ‘megalomaniacal’ self-advertisement of his chapter titles, and brazenly claims ‘I am not a man, I am dynamite’ as he attempts to explode one preconception after another in the Western philosophical tradition. In recent decades there has been increased interest in the work, especially in the English-speaking world, but the present volume is the first collection of essays in any language devoted to the work. Most of the essays are selected from the proceedings of an international conference held in London to mark the centenary of the first publication of Ecce Homo in 2008. They are supplemented by a number of specially commissioned essays. Contributors include established and emerging Nietzsche scholars from the UK and USA, Germany and France, Portugal, Sweden and the Netherlands
Drivers of negative phonotaxis for common carp (Cyprinus carpio) in response to resonant insonified bubble curtains
No full textThis thesis investigates the potential for insonified bubble curtains that use the resonant properties of bubbles to be used as behavioural deterrents for fish. This can help mitigate the ecological impacts of river and estuarine infrastructure such as hydropower technologies. To this end, in a series of four flume experiments, the following was tested: (1) the reactions of fish to a low air flow bubble curtain; (2) the effect of deconvoluting visual cues from stimuli generated by the bubble curtain; (3) the effectiveness of resonant versus non-resonant insonified bubble curtains to deter passage, determining the stimuli responsible for eliciting deterrence; (4) the question of whether regions with different levels of particle motion or acoustic pressure influence fish behaviour. Models of the extinction cross-section for each bubble population were used to explain the acoustical effects, confirming bubble resonance. Results of this fundamental study showed that bubble clouds with a higher proportion of resonant bubbles were better at deterring fish passage and this was likely influenced by multimodal cues, specifically, particle displacement, and sound pressure within a body length of the fish. All insonified bubble curtains were less effective in the presence of visual cues, likely because when available these are given greater importance by fish over mechanosensory cues. The benefits of energy-efficient, resonance-based acoustic behavioural deterrents examined by this thesis may be explored further for field-based applications. Finally, the importance of avoiding certain historical pitfalls when characterising acoustically active bubble curtains is discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
