Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Toward complex models of complex systems - One step further in the art of Agent-Based Modelling
No full textAgent-Based Modelling has now become a relevant and recognized paradigm to design integrated models of complex systems such as socio-environmental systems. The MAELIA modelling project, that aims at assessing various water with drawal policies, is a typical example of such complex models: it couples physical dynamics (e.g.water flow and plant growth) with agricultural activities (e.g.cropping plan decision-making) to provide a Decision-Support System about water management policies. Working on such a complex model has highlighted the limits of tools and methods currently used in modelling projects. This dissertation aims at investigating more particularly three research axes that appear necessary to improve the way we design and use agent-based models. First, the dissertation focuses on the integration of complex and cognitive agents in agent-based models. Agent-Based Models are usually designed with very simple agents and these models are generally abstract and focused on a specific process (e.g.opinion diffusion). But it has appeared necessary to integrate, in socio-environmental system models, agents able to make complex decisions (such as cropping plan decision by farmer agents in the MAELIA model) and to reason about others in large-scale artificial societies. To this purpose, a BDI architecture coupled with a multi-criteria decision-making process has been proposed and integrated in the GAMA platform. In addition, models of agents with complex social cognitive capabilities (e.g.trust and social emotions) are presented. The second research axis deals with the integration of models using different paradigms into an agent-based model, and more specifically with the coupling of Agent-Based Models with Ordinary Differential Equation models. This coupling is illustrated with the abstract MicMac model and more recently with a model of Dengue spread investigating the causal relationship between the opening of an economic corridor in South-East Asia and the number of Dengue fever cases. These models highlight (i) the benefits that the coupling of agent-based models (generative model at the microscopic level) with equation-based models (descriptive model at the macroscopic level) can bring to modellers, but also (ii) the methodological and technical difficulties of this coupling. Finally, the last research axis focuses on issues related to data and data management in agent-based models. Agent-based models in general and socio-environmental models in particular require a huge amount of input data; they also produce a lot of data that needs to be analysed for calibration purposes or even to support decisions. To deal with these challenges, an integrated framework combining simulator, database management system and Business Intelligence tools is presented; its global architecture, implementation and application to a Abstract case study (rice pests invasion monitoring in the Mekong delta) are also detailed. One of the main characteristics of the research activity presented in this dissertation is that all the works have been implemented in one single agent-based platform, GAMA (developed incollaboration between the IRD and several French and Vietnamese universities), that is usedin numerous training sessions every year (MAPS, MISS-ABMS, JTD). After the description of the three previous axes, the last section of this dissertation focuses on research perspectives concerning the use of qualitative data (inquiries results, testimonies,interview...) to build, feed (at initialisation) and inform (during the simulation runtime) agent-based models and simulations
