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
The Development of Mobile Robot Platform for Urban Search and Rescue Environment
Get PDFSearch and rescue (SAR) mission always takes place when disasters happen. Disaster could be defined into two categories, namely natural disaster and man-made disaster. Natural disasters normally cover a large area making the SAR mission’s team require an aerial view from airplane. This is because it changes the geographical landscape of the affected areas in huge perimeters. The impact is not only changing the whole landscapes, but it also impacts on residences, commercial buildings, transportations and communication infrastructures. This is always the primary reason of choosing an air vehicle as a first respond for any natural disaster. Meanwhile, made-made disasters occur in small areas relative to natural disaster. Terrorist bombing, structural collapse because of human failures or serious accident are some examples of man-made disaster. In addition, the effect from natural disaster such as earthquake also resulting horrendous structural collapse. The challenges for this rescue operation are focused on the interior of the rubble and entire external extent of the damage often not as primary interest because most victims are trapped inside, under the rubbles. Locating, extracting and rescuing any survivors will become the main goal for any rescue mission. Besides, the mission also deals with a lot of potentially dangerous situation such as further collapse, explosions, hazardous gas leaks and fire. Extreme high temperature from fire or explosions prevent rescuer to go down further into rubbles. Urban search and rescue (USAR) is the term that is being used recently for the rescue operation after man-made disaster. Conventionally, dog has been used to identify location of any potential survivors in the rubble. Again, capabilities of dog rescuer are restricted by certain working temperature, uncertainty of void size and fatigue factor. USAR operation is like race against time where trapped survivors cannot wait any longer. Further collapse or explosion may happen anytime. Therefore, the rescue team should have ideal strategy and tactic in order to maximize numbers of survivors being extract from rubble but also minimise the risk face by rescuer. Hazards is everywhere at disaster site. Human rescuers as well as dog are exposed to danger such as further collapse which would trap them in rubble and resulting an increased number of victims. This kind of situation make USAR uncertain. As a result, hazard identification and situation awareness have to be conducted concurrently with finding survivors. Robotic system, in many ways, have shown its versatility in wide range of applications. For instance, a modern and sophisticated automative assembly plant employ robotic systems in the production line in order to fullfil a specific part assembly task. On the other hand, robotic systems also started to be used as exploration vehicle in unknown world such as deep sea and outer space exploration purposes. In many aspects, the implementation of robotic systems in these applications have a significant impact to the overall process flow of the specific application. Having said that, mobile robots use in many deep sea explorations help scientists to discover the 'underworld' where human cannot explore. Therefore, implementation of robotic system in USAR operation is inevitable. In fact, it has been used in several USAR operation including the 9/11 World Trade Centre tragedy and Fukushima Daiichi Nuclear Power Station. The physical design of mobile robot is one of the main challenges to implement robotic system in USAR operation. The ability to manouver and negotiate with rough terrain is highly essential. In addition, the physical design is also need appropriate sensors in order to sense the environment. Therefore, the overall mechatronic structure must consist a robust platform equipped with sensors and actuators and able to navigate seemlessly on extreme rough terrain as well as perform designated task (e.g., find survivors, clean debris or conduct onsite disaster assessment). In order for a mobile robot to operate in unknown world such as USAR environment, it is crucially important for the mobile robot to have certain level of autonomy to plan a desired behaviour and act according to the surrounding. Eventhough it is very challenging to program a mobile robot for this type of environment, a comprehensive control architecture provide a systematic overview of the overall programming structure whilst simplifiying the programming procedure. On top of that, the ability of the overall robot system to plan and track its mission is clearly present in the control architecture. Navigation problem, which is one of the common problem in any exploration robot, also can be solved systematically. In general navigation task, a mobile robot is required to move according to the prior designated trajectory, normally in 2-dimension (flat surface). However, a mobile robot that is design for the USAR operation should be able work and navigate in unknown, uncertain and complex environment. This thesis describes the development of a mobile robot system motivated by the shape-shifting or variable geometry tracked vehicle (VGTV) configuration. The mobile robot is designed with expectation to be able to traverse on various types of terrain and enhance stability to prevent tip-over mishap. The practical work is evaluated by experimental trials on prepared terrains such as staircase, ramp and curb. On top of that, the control framework is outlined to set the objectives of the mobile robot system based on the control hierarchy. This set of works is further simulated with the aim to solve navigation problems as well as to determine the mobile robot behaviour when it is required to travel on uneven surface
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
