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
Variations on the Author
Full text link“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
Soft, wireless electronics for the thermal characterization of skin and soft tissue
Full text linkExisting sensors to monitor physical biomarkers in living tissue are rigid, bulky and often require wired electronic connections for power and data transfer. Recent work has established a set of design principles that allow for the integration of traditionally rigid sensing electronics and wiring into form factors that are soft, flexible and stretchable. These sensors offer qualitative improvements in patient comfort and are comparable, if not superior to clinical gold standard technologies. The strong, conformal mechanical coupling between these sensors and underlying living tissue also opens new avenues for unusual sensing modalities with immediate applications in clinical medicine. Devices for the continuous thermal characterization of living tissue represent one such opportunity and the work presented here illustrates a set of materials, mechanics and electronics designs required to realize fully functional sensors for temperature and flow mapping through biological conduits. Advanced powering and data transmission and powering schemes relying on near-field communication and Bluetooth protocols allow the sensors to be continuously worn for extended periods. Measurements of hydration in outer skin layers, cerebrospinal fluid flow through indwelling ventricular shunts and blood flow through peripheral nerve vasculature represent three use cases in dermatology, neurosurgery and neuroscience, respectively. Systematic benchtop and theoretical studies illustrate the high levels of functionality of these devices, and IRB approved studies on over 30 patients and volunteers, along with comparisons to clinical gold standards highlight their potential beyond the laboratory.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-08-01The student, Siddharth Krishnan, accepted the attached license on 2019-06-01 at 19:10.The student, Siddharth Krishnan, submitted this Dissertation for approval on 2019-06-01 at 19:14.This Dissertation was approved for publication on 2019-06-11 at 10:22.DSpace SAF Submission Ingestion Package generated from Vireo submission #14013 on 2019-11-26 at 13:59:35Made available in DSpace on 2019-11-26T20:56:45Z (GMT).

Screen Printed Graphene Oxide Textile Biosensor for Applications in Inexpensive and Wearable Point-of-Exposure Detection of Influenza for At-Risk Populations
No full textA textile screen-printed biosensor was developed using silver conductive electrodes and graphene oxide transduction film built upon both nanoporous polyamide and consumer utility textiles for the detection of environmental exposure to influenza A virus. An affinity assay was constructed upon the graphene oxide layer to introduce influenza protein-specific antibodies to the sensor surface. Validation of fabrication reproducibility and stability, as well as affinity assay stability, was conducted using electrochemical impedance spectroscopy. The textile sensor was utilized for the detection of influenza A in biofluid analog buffer. Its linear dynamic range was from 10 ng/mL to 10 µg/mL with a limit of detection of 10 ng/mL, spanning both pre- and post-symptomatic ranges. The sensor can be integrated into common textiles and worn by at-risk populations to detect exposure to the virus before symptoms manifest. If integrated with Internet-of-Things reporting platforms, this sensor could have the ability to predict potential influenza outbreaks before broad symptoms manifest, reducing the physical and economic burden of the disease. © The Author(s) 2018.Erik Jonsson School of Engineering and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
