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
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
Design Methods in ISO 13628-12 and Implications for Gulf of Mexico SCRs
No full text
Abstract
A new riser code, ISO 13628-12 "Design of Dynamic Risers for Floating Production Installations" has recently been updated as part of an industry JIP and is scheduled for ISO ballot in 2010. Once approved, the new ISO 13628-12 will replace the current edition of API RP 2RD as the Code of Practice for the design of dynamic metallic risers for floating production installations. This paper summarizes the four design methods in draft ISO 13628-12 and investigates their implications on the design of future SCRs. The implication of the new riser design code is illustrated by an example of an SCR design in the Gulf of Mexico. Three of the four design methods allow for certain plastic utilization of the riser cross section, which requires additional considerations for design, analysis, material selection and fabrication. Combined loading code checks with the four different methods are performed and the results are compared. Additional material specific considerations including design stress-strain curve and fabrication requirements are also presented.
Introduction
The design methods in the updated draft ISO 13628-12 reflect an evolutionary progression from working stress design to limit state design. Limit state design ensures a consistent safety level, based on acceptable failure probabilities, with due considerations to the inherent uncertainty in the design loads and resistance to such loads. Typical limit states for deep water riser design application include:–Accidental limit state (ALS)–Ultimate limit state (ULS)–Serviceability limit State (SLS)–Fatigue limit state (FLS)
The ALS is associated with events with an annual probability of less than 10-2 and larger than 10-4, while the ULS corresponds to 100 year return period events or events with 10-2 annual probability. The SLS criteria define the loads during the normal operational conditions and normal temporary events. FLS is an ultimate limit state from accumulated excessive fatigue crack growth or damage under cyclic loading.
The performance criteria for the riser design depend on the specific limit state. For example ULS requires that the riser system must survive the design event with no damage, i.e. remain intact and avoid rupture, but not necessarily be able to operate. For ALS the riser system must survive, and may sustain some damage without any rupture i.e. no release of hydrocarbon is allowed. Typical load cases for strength design of SCR are presented in Table 1.
The paper presents a summary of the design equations to assess the capacity of the pipe. The performance of an 18 inch oil (X70 grade steel) export SCR suspended from a semi-submersible in 2000 m water in the Gulf of Mexico is assessed for ULS and the ALS conditions using combined loading equations for internal overpressure conditions. Potential for buckling due to compression in the touchdown zone (TDZ) is also investigated.

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
