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
A Fault Diagnosis System for Industry Pipe Manufacturing Process
Get PDFIt can be very costly for a process where an expert system and experience human being needed in certain circumstances. Without an expert system, his/her experience is loss where human is unavailable. This ‘human replacement’ process is certainly a convenient way to be applied. With the expert system, processes or tool that implemented will be standardized and accuracy will be increased comparing to the conventional way. Constrain values for the fault diagnoses are based on design data and experience of the engineer. A case study was conducted to verify the system.
The development system helps user to find the best solution for the problems that occurred during the piping manufacturing process. The paper describes the used of expert system shell to develop piping fault diagnosis system in pipe manufacturing industries. The main aim of the research is to diagnose the problem of piping process in pipe manufacturing process
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
Total Design of Active Neck Support System for Economy Class Aircraft Seat
Get PDFTravel by air with long hours will create discomfort feeling for aircraft passenger especially economy class aircraft passenger. Long hour air travel will create physiological stress on aircraft passenger. It may due to seat space limitation, noise, vibration, cabin humidity as well as seat comfort. Seat comfort is a subjective feeling that related to psychological aspect of aircraft passenger. The
current aircraft passenger seat is equipped with a passive function where the passenger themselves needs to adjust the seat for comfort seating position. The aircraft passenger will not able to adjust the seat when the aircraft passenger is in the low activity condition. The active seat support system was developed to support the aircraft passenger actively. The first prototype of active seat support system
is focus on neck section. The head position of the aircraft seat was embedded with the system to detect the head position of the passenger. During the development of the active seat support system, total design technique was used. Five conceptual designs were generated for selection. To determine the final design of active neck support system, the matrix evaluation method was used. The weight of the
concept was obtained through weight analysis
The Self-Reported Seat Discomfort Survey on Economy Class Aircraft Passenger in the Netherlands
Get PDFThe economy class aircraft passengers who experience long hour sitting during air travel has experienced significant body discomfort at neck, shoulder, lower back, upper leg and lower leg. The questionnaire was set out to study the relationship between different body back part discomfort and
travel time of economy class aircraft passenger in order to rank the discomfort level for each body back part. There were one hundred and four anonymous self administered surveys were completed at Schiphol International Airport, the Netherlands. In line with the survey hypothesis, findings confirmed that the body discomfort of aircraft passenger after five hours travel is higher than after one hour travel. The body discomfort of economy class aircraft passenger is associated with flight duration. Further
studies concerning how to best provide comfort to long haul economy class aircraft passengers are needed. The survey presented in this paper will beneficial the aircraft passenger seat designers to facilitate future design and evaluate seats that able to reduce body discomfort during long haul air travel
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
