Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Supplemental data and R code for: A novel method for testing the impacts of pesticide exposure on soil-nesting insects: A case study using the ant Lasius neoniger and the neonicotinoid insecticide Imidacloprid
No full textDatasets related to the creation of a novel, cheap, replicable, and field relevant ecotoxicological laboratory method for testing non-target soil insects. Lasius neoniger is agriculturally wide-spread, and easy to rear under laboratory conditions. Soil applications of imidacloprid at below 0.1% of recommended field rates are lethal to a common non-target ant species. Imidacloprid significantly impacted ant grooming, decreasing chance of survival
Coherent diffraction imaging using a high harmonic source at 40 eV
No full textThis thesis presents the current status of coherent diffractive imaging and ptychography using the high harmonic at the University of Southampton. The full system used to generate the 40 eV radiation and collect the far-field speckle patterns is outlined and critical criteria discussed. The algorithms used to re-phase the data are outlined and some simple 1-dimensional examples are given. The question of how to appropriately state the resolution of a coherent diffraction system is addressed and the concluding results are applied to the work in the experimental chapters, of which this thesis contains two.The first, is a published result which investigates the treatment of partial temporal coherence through the coherent diffraction process. Partial coherence for a high harmonic source is slightly more complex to treat than standard broad-bandwidth sources since the spectrum is modulated by the narrow-bandwidth harmonic comb underneath a broad-bandwidth envelope. An experimental investigation is presented by illuminating the same amplitude mask under broad-band and narrow band conditions using the same imaging systems. The results are discussed and conclude that a much greater than expected (20%) relative bandwidth can used for such an experiment and still reproduce a reliable and fairly stable reconstruction. This construction is not a solution to the phase problem however, and hence only provides an improved support constraint for potential further processing.The second experimental chapter presents novel and currently unpublished work using the high harmonic source to obtain iterative ptychograms of complex-valued extended samples. This represents the first documented result of ptychography using a lab-based source of short wavelength radiation. Defects in the Molybdenum pinhole used to define the illumination function are investigated and provide a thickness for the defect area of 6 nm x 1 nm with a pixel size of 90 nm. The sample under investigation for this experiment was a substrate with fixed cultured hippocampal neurons. An investigation of one of the neurite processes of this sample is made and identification of the neurite as an axon is deduced via analysis of the samples dielectric loss tangent
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
