Emotion Modeling in Social Simulation: A Survey
No full textEmotions play a key role in human behavior. Being able to integrate them in models is therefore a major issue to improve the believability of agent-based social simulations. However, and despite the emergence of many emotional models usable for simulations in the last fewyears, many modelers still tend to use too simple ad hoc emotional models. To support this view, this article proposes a survey of the different practices of modelers in terms of implementations of emotional models, as well as a presentation of different emotional architectures that already exist and that could be used by modelers. The main goal is to understand how emotions are used today in social simulations, in order for the community to unify its uses of emotional agents
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
Toward cognitive, affective and social agents in simulation
No full textAu cours des dernières années, l'utilisation de simulations à base d'agents pour étudier les systèmes sociaux s'est étendue à de nombreux domaines (géographie, écologie, sociologie, économie, etc.). Ces simulations visent à reproduire des situations réelles impliquant des acteurs humains ; il est donc nécessaire d'y intégrer des agents complexes reproduisant le comportement des personnes simulées. Par conséquent, des notions telles que la cognition, les émotions, la personnalité, les relations sociales ou les normes doivent être prises en compte. Pour autant, il n'existe actuellement aucune architecture d'agent intégrant toutes ces caractéristiques et pouvant être utilisée par la majorité des modélisateurs, y compris ceux n'étant pas expert en programmation informatique. Dans cette thèse, l'architecture BEN (Behavior with Emotions and Norms) est présentée pour répondre à cette question. Il s'agit d'une architecture modulaire basée sur le modèle BDI de la cognition avec des modules pour ajouter des émotions, de la contagion émotionnelle, une personnalité, des relations sociales et des normes au comportement des agents. Ces dimensions comportementales sont formalisées de manière à ce qu'elles puissent fonctionner ensemble pour produire un comportement crédible dans le contexte des simulations sociales. L'architecture est implémentée dans la plate-forme de simulation GAMA afin de la rendre utilisable par la communauté des simulations sociales. Enfin, BEN est utilisé pour étudier deux cas d'évacuation d'une boîte de nuit en feu, montrant que l'architecture est actuellement utilisable à travers son implémentation dans GAMA et qu'elle permet aux modélisateurs de reproduire des situations réelles impliquant des acteurs humains.Over the last few years, the use of agent-based simulations to study social systems has spread to many domains (e.g. geography, ecology, sociology, economy). These simulations aim to reproduce real life situations involving human beings and thus need to integrate complex agents to match the behavior of the people simulated. Therefore, notions such as cognition, emotions, personality, social relations or norms have to be taken into account, but currently there is no agent architecture that could incorporate all these features and be used by the majority of modelers, including those with low levels of skills in programming. In this thesis, the BEN (Behavior with Emotions and Norms) architecture is introduced to tackle this issue. It is a modular architecture based on the BDI model of cognition featuring modules for adding emotions, emotional contagion, personality, social relations and norms to agent behavior. These behavioral dimensions are formalised in a way so they may operate together to produce a believable behavior in the context of social simulations. The architecture is implemented into the GAMA simulation platform in order to make it usable by the social simulation community. Finally, BEN is used to study two cases of evacuation of a nightclub on fire, showing it is currently usable throught its implementation into GAMA and it enables modelers to reproduce real life situations involving human actors
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
