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
Ep. #181 - Nigel Clark
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic discuss a strange effort to police sugar packet play on this week’s podcast. Then (15:52) we are delighted to welcome Nigel Clark to the conversation. Nigel is Chair of Social Sustainability and Human Geography at Lancaster University (https://www.lancaster.ac.uk/lec/about-us/people/nigel-clark ). He is the author of Inhuman Nature: Sociable Life on a Dynamic Planet (2011) and co-editor of Atlas: Geography, Architecture and Change in an Interdependent World (2012), Material Geographies (2008) and Extending Hospitality(2009). We start things off by talking about a new book he is working on called The Anthropocene and Societythat he is working on with Bron Szerszynski and what it means to rethink humanity through planetary strata, flows, and multiplicity. We turn from there to Australian feminism, phosphates, Aotearoa New Zealand as a space of settler grassland experiments, wealth, and geocide. Then we touch on fire and its excess, our brittle life on an earth’s surface caught between solar and geothermal vitalities, metamorphosis, the early connection between gunpowder and combustion engines and European geotrauma. A special birthday week shout-out to our very own eternal Cymene Howe :
Creative Chemistry
No full textPersons with a penchant for benzene rings, organic chemistry, and other related matters will find the Creative Chemistry a welcome addition to their references. The site collects hundreds of worksheets, teaching notes, and interactive quizzes for educators to use as they see fit. The site is maintained by Nigel Saunders, who has a biochemistry doctorate from the University of York, and includes twenty different thematic areas, including Balancing Equations, Concentration Game, The Slide Puzzle, and Chemistry Calculator. One section that should not be missed is called Molecular Models; as the name suggests, it features molecular models that visitors can play with at their leisure. Some of the models include alkanes, octahedral molecules, and isomers of organic compounds. Finally, visitors can search the site for specific topics via a helpful search engine

He obtained his PhD from the University of Cambridge in 1991 on the topic of Money in Social Theory, and lectured at the University of Liverpool before joining the LSE in 1995. Nigel’s main interests are in the sociology of money, economic sociology and classical and contemporary social thought. He is author of The Sociology of Money and Social Theory and Modernity (both published by Polity Press). His most recent book, The Social Life of Money, was published by Princeton University Press in September 2014
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
The majority of genes in the pathogenic Neisseria species are present in non-pathogenic Neisseria lactamica, including those designated as 'virulence genes'

Neisseria gonorrhoeae is closely related to the meningococcus, but is the cause of the very different infection, gonorrhea. A number of genes have been implicated in the virulence of these related yet distinct pathogens, but the genes that define and differentiate the species and their behaviours have not been established. Further, a related species, Neisseria lactamica is not associated with either type of infection in normally healthy people, and lives as a harmless commensal. We have determined which of the genes so far identified in the genome sequences of the pathogens are also present in this non-pathogenic related species. Results: Thirteen unrelated strains of N. lactamica were investigated using comparative genome hybridization to the pan-Neisseria microarray-v2, which contains 2845 unique gene probes. The presence of 127 'virulence genes' was specifically addressed; of these 85 are present in N. lactamica. Of the remaining 42 'virulence genes' only 11 are present in all four of the sequenced pathogenic Neisseria. Conclusion: Assessment of the complete dataset revealed that the vast majority of genes present in the pathogens are also present in N. lactamica. Of the 1,473 probes to genes shared by all four pathogenic genome sequences, 1,373 hybridize to N. lactamica. These shared genes cannot include genes that are necessary and sufficient for the virulence of the pathogens, since N. lactamica does not share this behaviour. This provides an essential context for the interpretation of gene complement studies of the pathogens.This study is supported by the Wellcome Trust

Population-associated differences between the phase variable LPS biosynthetic genes of Helicobacter pylori
No full textThis is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited - © 2006 Salaün and Saunders; licensee BioMed Central Ltd.Background: Population structures are normally determined using genes under minimal functional selection. In this study we have assessed genes that are not always essential, show differences in alleles between strains, and are involved in the directly host-selectable phenotype of LPS biosynthesis. Results: Eight complete LPS biosynthesis genes, seven of which are associated with phase variation in some or all strains of Helicobacter pylori, have been sequenced and their divergence analyzed. The differences observed indicate that recombination within these genes largely reflects exchange between strains within the population lineages previously determined on the basis of MLST using housekeeping genes. This indicates that the differences that are used for MLST are likely to broadly associate with genes under functional selection, and differences in strain behaviour. However, instances of exchange between the subpopulations were identified, including the hpAfrica2 subpopulation. Further, there were other differences in gene complements and the chromosomal location of genes indicative of greater diversity within the population than is revealed by the available genome sequences and comparative genome hybridization studies. Conclusion: These results indicate that the described population structure based upon MLST is broadly a good basis for studying the biology of H. pylori, but that individual alleles may not follow these associations. As a consequence, when working in unsequenced strains, it is necessary to carefully check the presence, sequence, and distribution of any individual gene of interest.This work is supported by a Wellcome Trust Advanced Fellowship

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
