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
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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Deeply implanted medical device based on a novel ultrasonic telemetry technology
Get PDFMedical devices have gone a long way since their beginning. In the last decades, the trend has been towards Implanted Medical Devices (IMDs). The technology evolution has provided the necessary tools for longer-term, less invasive devices. Several devices for sensing and actuation are commercially available and ease therapy management, while preserving the patient’s life quality. An ideal implant would integrate both sensing and actuating possibilities in a feedback loop, thus achieving optimum therapy. To reach this goal, several challenges remain, in particular concerning power supply and miniaturization. Solving these issues would open new possibilities and allow applications which are not possible yet: better diagnosis could be achieved wherever a continuous, long-term monitoring of physiological parameters in real life conditions is required. For instance, smaller and deeper implanted devices would allow deploying several IMDs in the body, achieving a Body Sensor Network (BSN). Beside therapy, implants could be used for diagnosis in populations at risk. Furthermore, minimal invasive implants would greatly improve medical research, by allowing closer observation, thus helping to understand physiological mechanisms. This thesis describes the author’s contribution to the development of a novel IMD concept, proposed within the European FP7 project ULTRAsponder. The author focused on the integration aspects in the design and manufacturing process of the novel implantable device platform: definition of the technical specifications, assessment of appropriate commercial components, geometrical placement of the Printed Circuit Boards (PCBs) inside the casing, choice of a suitable housing material, and assessment of its effect on the energy transmission. The target is a generic BSN node, which can be implanted wherever needed on a long-term basis and which can operate autonomously. Key features of the proposed system include remote powering of the implanted device and communication with an external Control Unit (CU) by backscattering modulation. For both energy and data transfer, an ultrasonic carrier is used instead of Electromagnetic (EM) waves because it is compatible with Magnetic Resonance Imaging (MRI) and does not interfere with EM emitters like mobile phones and electronic equipment. It also proved to be more efficient than the use of Radio Frequency (RF) waves or magnetic induction to reach deep implants and when using small transducers. The user requirements and the technical constraints towards an optimal implant were evaluated and the characteristics of the proposed system were defined. Appropriate commercial components and emerging technologies were identified, which allowed the development of the device. The originality of this work lies in the integration of different technologies, components and scientific approaches into a novel, promising IMD. In particular, the challenge of achieving an ultrasonic link through a standard medical grade titanium casing is addressed. Titanium casings are the golden standard for biocompatible device housing, but they have a strong influence on ultrasonic energy transfer. Successful integration of ultrasonic transmission and titanium casing ensures the ability of the proposed device to be industrially exploited and commercialized. A demonstrator implant and an external CU have been manufactured, focusing on energy transfer, signal treatment, and backscattering. A commercial, rather large housing was used, in order to demonstrate the industrial viability of the device. In vitro tests validated the energy transfer and the communication between the CU and the Transponder (TR), as well as the user interface. Assessment in real conditions is achieved by in vivo tests on pigs. Functionality was proved, however at a much smaller distance than intended. Future work includes optimization of the ultrasonic transfer, integration of the sensing circuitry, and miniaturization of the resulting device.LP
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
