When should we refer our patients for cosmetic surgery?
No full text Despite the increasing number of aesthetic procedures that can be performed non-surgically, some patients and conditions require referral to surgeons with the relevant expertise. But making referrals for cosmetic surgery is not something medical aesthetic trainers tend to discuss, so when is it appropriate? Rajveer Thethi reflects on the surgical past and present of aesthetic medicine and its relevance today </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
In-situ Investigation of Subsurface Porous Media Processes: Microfluidics and Chemical Imaging
No full textRajveer Singh - Research Associate, Beckman Institute, University of Illinois at Urbana-Champaign.
Improved understanding of microbe-water-subsurface porous media interactions that control biogeochemistry in subsurface aquifer and reservoir systems is critical from the prospective of a number environmental issues, such as Geological carbon sequestration, Bioremediation of Groundwater systems, and Energy resources recovery from subsurface. My approach involves using 2D microfluidic experimental test bed, usually called micromodels, to simulate subsurface hydrodynamic environment that allows in-situ visualization, tracking and quantification of biogeochemical reactions in subsurface reservoir systems. Several examples from reservoirs systems including bio-mineralization of CaCO3 during reactive transport in porous media its impact on pore space alteration and process efficacy and contaminants’ mixing enhancement during bacterial random motility will be discussed. A novel design of 2D- microfluidic experimental flow bed, based on real geo-materials as opposed to engineered materials in traditional micromodels, will be discussed. Finally, chemical imaging (Raman and Infrared spectroscopy) methods will be discussed for in-situ characterization of biogeochemical reactions in the flow cells as well as alternate analytical techniques in environmental engineering.Open Restriction set for Item 114498 on 2020-04-21T19:05:22Z with date null by [email protected] by Elizabeth Meschewski ([email protected]) on 2020-04-21T19:08:13Z

Variations on the Author
No full text“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
No full textWe 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
An Improved DEEHC to Extend Lifetime of WSN
No full textSensor networks consist of randomly deployed nodes that are powered by smaller batteries. The quantum and quality of information sensed by these nodes is of vital importance. Battery saving techniques or algorithms are need of the hour. One such technique is clustering of the nodes. This paper presents modification to existing DEEHC algorithm that builds multiple vertex disjoint paths from nodes to base station via cluster heads. The proposed modification MDEEHC improves the performance of the network as equated to DEEHC and FLDEEC by relaying the data of the child cluster heads using relay nodes. MDEEHC shows improvement in terms of throughput, packet delivery ratio, number of packet drops and remaining energy.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
