Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
Do incremental increases of the herbicide glyphosate have indirect consequences for spider communities?
No full textThe effect of the herbicide glyphosate on non-target spiders: Part I. Direct effects on Lepthyphantes tenuis under laboratory conditions
No full textWe examined the toxic effects of glyphosate to adult female Lepthyphantes tenuis (Araneae, Linyphiidae), a common spider of agricultural habitats. The overspray technique was used to investigate the effect of the herbicide on forty individuals in each of six glyphosate treatments (2160, 1440, 1080, 720, 360 and 180 g ha−1) and a distilled water control. Spiders collected from the wild were individually placed in exposure chambers and checked every 24 h over a 72-h experimental period. Mortality of L tenuis remained at less than 10% in all treatments at 24 and 48 h after spray application, and only increased marginally (to 13%) after 72 h. These results support other limited data which suggest that glyphosate is ‘harmless’ to non-target arthropods. More extended laboratory testing to investigate any side-effects of glyphosate on the life history of L tenuis and other non-beneficial invertebrates is required
The effect of the herbicide glyphosate on non-target spiders: Part II. Indirect effects on Lepthyphantes tenuis in field margins
No full textWe have examined the indirect effect of the herbicide glyphosate on the spider Lepthyphantes tenuis in field margins. Glyphosate was applied to a randomised block design field experiment comprising 360, 720 and 1440 g glyphosate AE ha−1 treatments and an unsprayed control. Spiders were sampled in each month from June to October 1998. Spider abundance was significantly lower in all the treatments than in the unsprayed control. Abundance was also significantly lower in the 720 and 1440 g treatments than in the 360 g treatment. No significant difference could be detected between the 720 and 1440 g treatments. Poisson regression models showed that patterns of decline in L tenuis were related to increasing dead vegetation and decreasing vegetation height. Glyphosate applications only had a within-season indirect habitat effect on L tenuis as field margins sprayed 16 months after an application of 360 g glyphosate ha−1 showed no detrimental effect
The Writer Walking the Dog: Creative Writing Practice and Everyday Life
No full textCreative writing happens in and alongside the writer’s everyday life, but little attention has been paid to the relationship between the two and the contribution made by everyday activities in enabling and shaping creative practice. The work of the anthropologist Tim Ingold supports the argument that creative writing research must consider the bodily lived experience of the writer in order fully to understand and develop creative practice. Dog-walking is one activity which shapes my own creative practice, both by its influence on my social and cultural identity and by providing a time and space for specific acts instrumental to the writing process to occur. The complex socio-cultural context of rural dog-walking may be examined both through critical reflection and creative work. The use of dog-walking for reflection and unconscious creative thought is considered in relation to Romantic models of writing and walking through landscape. While dog-walking is a specific activity with its own peculiarities, the study provides a case study for creative writers to use in developing their own practice in relation to other everyday activities from running and swimming to shopping, gardening and washing up
Semiometrics: Applying Ontologies across Large-Scale Digital Libraries
No full textAs large-scale digital libraries become more available and complete, not to mention more numerous, it is clear there is a need for services that can draw together and perform inference calculations on the metadata produced. However, the traditional Relational Database Management System (RDBMS) model, while efficiently constructed and optimised for many business structures, does not necessarily cope well with issues of concurrent data updates and retrieval at the scale of hundreds of thousands of papers. At the same time the growth of RDF and the increasing interest in Semantic Web technologies perhaps begins to present a viable alternative at a scalable, practical level. This paper considers a specific application of large-scale metadata analysis and conducts scalability tests using real-world data. It concludes that RDF technologies are both a scalable and performance-realistic alternative to traditional RDBMS approaches. It also shows that for relationship-based queries on large-scale metadata stores, RDF technologies can significantly out-perform traditional RDBMS approaches by allowing both retrieval and updating of data in a timely manner
Combustion and Society: A Fire-Centred History of Energy Use
No full textFire is a force that links everyday human activities to some of the most powerful energetic movements of the Earth. Drawing together the energy-centred social theory of Georges Bataille, the fire-centred environmental history of Stephen Pyne, and the work of a number of ‘pyrotechnology’ scholars, the paper proposes that the generalized study of combustion is a key to contextualizing human energetic practices within a broader ‘economy’ of terrestrial and cosmic energy flows. We examine the relatively recent turn towards fossil-fuelled ‘internal combustion’ in the light of a much longer human history of ‘broadcast’ burning of vegetation and of artisanal pyrotechnologies – the use of heat to transform diverse materials. A combustion-centred analysis, it is argued, brings human collective life into closer contact with the geochemical and geologic conditions of earthly existence, while also pointing to the significance of explorative, experimental and even playful dispositions towards energy and matter. © 2014, SAGE Publications.

M.R.James and Nigel Kneale
No full textIn 1973, the Folio Society published its collection of Ghost Stories of M.R.James. In keeping with the publisher's practice of commissioning new introductions from then-active academics or authors, the stories were introduced by the television playwright Nigel Kneale (1922-2006) best know as the creator of the three Quatermass series - The Quatermass Experiment (1953), Quatermass II (1955), Quatermass and the Pit (1957), and the stand-alone play The Stone Tape (1972) which, like James' stories, was specifically written for Christmas.
Together with H.G. Wells and John Wyndham, M.R.James is the author most frequently mentioned as influencing Kneale's style - the four can be grouped together as a tradition of horror based on realism and detail. It's. a very English tradition - although that's a slightly contentious word when applied to the Manxsman Kneale - that carries on in works such as both the classic and revived Dr Who. In his introduction, Kneale notes this quality, with what reads to me like a slight note of weariness that he's having to explain it again: 'The verisimilitude performs its usual trick in such tales, conditioning us to accept the unbelievable and doubling the shock when it does hit us.' (ix)
In both Quatermass and the Pit and The Stone Tape, Kneale nods towards the earlier author, including clerical antiquarians of the sort that James tended to make into his protagonists. In this respect, Kneale's world is far larger than James' - these characters are functionaries, rather than the central figures they would have been in James. My paper will examine how James' influence plays out in Kneale's work, and how both the similarities and the differences between them tell us something about both writers
Detection of Cognitive Features from Web Resources in Support of Cultural Modeling and Analysis
No full textThe World Wide Web serves as a valuable source of culture-relevant information, which can be used to support cultural modeling and analysis activities. Part of the challenge in exploiting the Web as a source of culture-relevant information relates to the need to detect and extract information about beliefs, attitudes, and values from a variety of different resources. The Web thus features a rich variety of information resources, and these are seldom categorized with respect to the dimensions in which cultural analysts are interested. Exploiting the Web as a source of culture-relevant information therefore requires techniques and approaches that enable cultural analysts to extract relevant information and organize extracted content in various ways. In this paper, we outline an approach to assist cultural analysts in the extraction and organization of relevant information. We show techniques that can be used to extract information about the attitudes, beliefs, and values of individuals, and how this data can, in turn, be used to support cultural modeling and analysis
