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
Clough hazardous area tool
Get PDFThe need for the adequate management of information has become increasingly prevalent as minimum safety requirements in today’s work place become ever more stringent. This is particularly apparent in the Oil and Gas industry, where the additional presence of flammable gases or liquids is a continual threat to both plant and personnel. Existing management processes are typically manual exercises consuming numerous man hours on-site and in-office. The ability to automate fragments of current information management processes presents an exceptional opportunity to increase efficiency and productivity, ultimately saving time, money and in some instances increasing safety.
Clough Ltd, an Australian engineering, procurement, construction and management contractor whom primarily focus on the Oil and Gas industry, aim to enhance their project delivery capabilities and credibility with the development of the Clough Hazardous Area Tool (CHAT). The CHAT application is intended to provide a level of automation to existing hazardous areas management processes. It is envisioned to be a semi-automatic user centred application that will assist users in various scopes of work by interfacing with existing systems within Clough. This industry thesis is primarily concerned with the high-level planning, scheduling and budgeting of the CHAT project, as well as the detailed design and development of the hazardous area database.
The CHAT database has been designed in the format of a three-tier relational database model and is intended to utilize a serverless computing platform in an effort to reduce operating costs and virtually eliminate the need for server provisions and maintenance. With the use of three data models (user interface, semantic and entity-relationship), 32 normalised tables or data instances have been created to cover the spectrum of HA data and documentation including but not limited to applicable standards and regulations, protection techniques and site equipment.
Unfortunately, the development of the CHAT project, which was intended to incorporate multiple final year computer science thesis students, has been put on hold. Delays are the result of larger than expected project costs, which have not been internally approved within Clough.
Following a series of meetings and presentations with executive committees from Clough and Clough subsidiaries, the Project Team are hopeful approval and funding will be granted in mid- December 2019
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

Design, build and test of solar thermal air heating system with application
Get PDFThe adverse effects on the environment that are associated with the use of fossil fuels has promoted the research and adoption of alternative fuels such as wind and solar. The high costs associated with the purchase of fossil fuels have been another factor that has led to increased use of solar energy in the past decade. This project aims to design and build solar thermal air heating system for education purpose to teach engineering students as well as for researchers at Murdoch University. This will help to create a greater understanding of the different aspects of the solar air-heating system operation.
A mathematical model was created in excel spreadsheets so that the solar air-heating system could be tested so as get an idea of what the actual system would produce regarding maximum temperature and energy. From the results that were generated, it was observed that the maximum temperature varied depending on the period of the year. It was also observed that changing the configurations of the system resulted in different outlet temperatures. For example inclusion of the recycle effect in collector led to a significant increase in the outlet temperature of the collector; the temperature increased from 290C to 370C. Incorporation of the recycle effect in the oven resulted in even higher temperature gains, with the temperature rising to 51%. The percentage of the recycle effect was also observed to affect the outlet temperature, increasing the recycle percentage from 30% to 50% led to higher temperatures in all the tested cases
