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
Intuition Does Not Lie: The Effect of Individual Differences on the Ability to Accurately Detect Deception.
Full text linkDeception detection ability is an area that is not short of research, yet there is currently no definitive explanation for why some people are better than others at spotting a liar. This study surrounds individual differences in deception detection ability of high-stakes lies, and focuses on emotional intelligence level, susceptibility to emotional contagion and facial emotion recognition ability as variables. As these individual differences are all related to emotion-processing, and due to the often emotional nature of high-stakes lies, it is hypothesised that a relationship will be found between deception detection ability and each of these variables. Participants (n=60) completed the Schutte Self-Report Emotional Intelligence Test [SSEIT] (Schutte et al., 1998), the Emotional Contagion Scale (Doherty, 1997), and Ekman and Friesen’s (1976) Pictures of Facial Affect test, before viewing ten video clips of real life footage of individuals making televised pleas for the safe return of their relative or significant other. Participants were asked to make a veracity judgement of the appealer in each clip. The data was analysed through a standard multiple regression, though no statistically significant results were found to indicate relationships between the variables, conflicting with previous research. Further research is required to gain a greater insight in to each of these variables, though this study has provided a new insight in to the research area surrounding emotional contagion
How to catch a liar: The Effect of Communicative Channels on Accuracy in Detecting Deception in High-Stakes Situations
Full text linkMuch past research states people are generally quite poor at detecting deception, with meta-analytic findings reporting an average accuracy rating of 54% (Bond & DePaulo, 2006). However, the majority of these previous findings stem from the use of ‘low-stakes’ lies as stimuli. This current study used real-life video clips of a ‘high-stakes’ nature, investigating the effects of three different communicative channels on a novice lie detector’s ability to detect deception; an Audio-Visual channel, a Visual-Only channel and an Audio-Only channel. The effects on both participant accuracy and participant confidence scores were analysed, with further investigation into a potential relationship between participant accuracy and confidence. On reviewing previous literature, the current study hypothesized the following; participant accuracy in detecting deception across all modalities will score above the level of chance; the highest accuracy scores will be found within the Audio-Visual condition; the Audio-Only condition will produce higher levels of accuracy than those found in the Visual-Only condition; the Audio-Visual condition will produce the highest confidence ratings; no relationship will be found between overall levels of accuracy and confidence ratings reported. The current study also explored what behavioural cues are relied upon by novice lie detectors in their attempts to identify deception. No hypothesis was generated for the justification of decisions i.e. (the cues participants report using). However, information provided will help identify what behavioural cues members of the general public rely upon when detecting deception. A total of 60 participants were recruited for the current study, with an equal number of participants observing video-clips within each presentation modality (n=20). 8 video-clips were shown, all involving real-life ‘high-stakes’ situations i.e. an appeal for a missing relative. Half of the clips involved innocent individuals (telling the truth and not involved in the crime) and the other half were deceitful (involved in the crime and attempting to deceive observers). Overall, participant accuracy scored significantly above the level of chance (M=55, t(59)=2, p=0.05.). No statistically significant differences were found in participant accuracy and participant confidence between the three presentation modalities F(2,57)=.36, p=.70, n2=0.01; F(2, 57)=.58, p=.84, n2=0.02. Nor was a significant relationship observed between participant accuracy and participant confidence r(60)=.11, p=.43. Participants reported relying on behavioural cues involving ‘Nervous Behaviours’ and ‘Fake Emotion’ when determining a sender’s veracity. Implications and suggestions for future research are discussed
The Effect of Channels of Communication on Accuracy in Detecting Deception in High-Stakes situations
Full text linkMuch of the past research into deception detection has utilised low-stakes lies as stimulus, with globally poor results in accuracy levels. The present research used real-life recordings of high-stakes lies to investigate a between-subjects model of four different channels of communication: Audiovisual; Visual Only; Audio Only; Transcript Only. The dependent variable was the accuracy score obtained in each channel of communication in detecting deception. Considering available research results, it was hypothesised that the Audio Only group would score significantly higher than the Visual Only group, the Audiovisual group would score significantly higher than the Transcript Only group, and that the Transcript Only group would score significantly higher than participants in the Visual Only group. The lack of research into the channel of communication of Transcript Only provided further rationale for the present study. Due to the high-stakes nature of stimuli materials it was hypothesised that all participants would score higher than chance. Each participant group (N=20) observed 20 clips of people making public pleas for information about a missing or murdered relative. Half of the clips included people involved in the crime (attempting to deceive the public) and the other half were innocent (truthful, and not attempting to deceive the public). Scores ranged between 50.8% accuracy (audio visual) and 56.5% accuracy (visual only). There was no statistically significant difference between mean scores, F(3,76)=.30, p=.826, η²=.01. T-tests were conducted to test accuracy levels within each group. Accuracy levels were not significantly above chance. Suggestions for further research are discussed
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
