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
Which optimal design for lottery linked deposit
No full textLottery-linked deposit accounts (LLDAs) are financial assets that provide an interest rate determined by a lottery. These accounts that combine savings and lot- tery have become very popular in recent years and in a number of countries (Guillen and Tschoegel). However, their existence cannot be explained in the framework of the expected utility model. Their popularity can only be understood in light of behavioral ?nance studies, especially if individual preferences are described by Kahneman and Tversky?s cumulative prospect theory (1992). Actually, this theory provides a good explanation for the emergence of these deposit accounts by integrating simultaneously risk-averse and risk-seeking behaviors. In this paper, we propose a behavioral analysis of these financial assets by assuming that investors individuals preferences obey cumulative prospect theory. We study how the structure of prizes of the LLDAs should be framed to appeal to and attract many investors.Our aim is thus to determine the optimal design of these financial assets.info:eu-repo/semantics/publishe
Entrepreneurial confidence, financial decisions and firms performance
No full textCette thèse explore empiriquement l'interaction entre les facteurs cognitifs liés à la confiance d'un entrepreneur, les décisions financières et la performance d'une entreprise. L'objectif de cette étude est d'analyser les effets de certaines variables cognitives spécifiques très présentes dans le contexte entrepreneurial et de mieux comprendre comment elles façonnent la structure du capital d'une entreprise et les décisions de financement entrepreneuriales. Nous nous appuyons d'abord sur une revue systématique de la littérature qui étudie quels sont les principaux facteurs cognitifs liés à la confiance entrepreneuriale et comment elle affecte les décisions et les résultats d'une entreprise. Deuxièmement, nous abordons la relation entre l'ESE et la collecte de fonds et la performance d'une entreprise dans la deuxième étude de la thèse. Une troisième étude aborde empiriquement trois facteurs cognitifs liés à la confiance d'un entrepreneur dans la décision d'emprunter des crédits bancaires. Le manuscrit apporte originalité et nouveauté en analysant les effets d'une classe spécifique de variables cognitives liées à la confiance d'un entrepreneurThis thesis empirically explores the interaction between cognitive factors related to an entrepreneur’s confidence, financial decisions, and a firm’s performance. The objective of this study is to analyze the effects of some specific cognitive variables highly present in the entrepreneurial context and better understand how they shape a firm’s capital structure and entrepreneurial funding decisions. We first rely on a systematic literature review that investigates what are the main cognitive factors related to entrepreneurial confidence and how it affects a firm’s decisions and firm’s outcomes. Second, we address the relationship between ESE and fundraising and a firm’s performance in the second study of the thesis. A third study empirically addresses three cognitive factors related to an entrepreneur’s confidence in the decision to borrow bank credits. The manuscript brings originality and novelty by analyzing the effects of a specific class of cognitive variables related to an entrepreneur’s confidence
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
