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
Mu Suppression, Mirror Neuron Activity, and Empathy
No full textThe ability to understand and interpret the actions and intentions of others is vital to human interaction as well as learning. The purpose of this study was to examine differences in mu suppression to different types of point light stimuli (upright, inverted, and random) and relationships between mu suppression and empathy. Participants (N=7) completed two empathy scales, the Interpersonal Reactivity Index (Davis, 1980) and the Empathy Quotient (Baron-Cohen & Wheelwright, 2004). In addition, EEG data was collected while participants viewed point light stimuli. EEG results indicated significant mu suppression at all central electrode sites for all three stimulus types. Exploratory correlational analyses revealed significant correlations between mu suppression indices and scores on the perspective-taking (PT) subscale of the Interpersonal Reactivity Index. Although future research is necessary, these results provide a basis for future inquiries.Psycholog
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
Spatial Depth Cues in Temporal Reasoning
No full textSpace is a foundational schema for reasoning about time and as a result time is conceptualized in terms of spatial reality. The ego-moving cognitive metaphor suggests that time is static and immobile and the self moves through it. Conversely, the time-moving cognitive metaphor suggests time moves through a stationary being and is not subject to manipulation from the observer. The present study examined the relationship between the two temporal orientations and spatial depth cues. Four depth cues were tested: relative size, atmospheric disturbance, object occlusion and linear perspective. Participants were primed by reading temporal sentences imbued with either ego-moving or time-moving characteristics. Participants then viewed images containing the depth cues and answered questions regarding time. After this, they answered eight temporal questions and completed the Zimbardo Time Perspective Inventory survey. There was a marginal main effect of priming condition indicating that there was a tendency for people to take a higher proportion of ego-moving responses in the ego-moving condition. The proportion of responses varied as a function of the cue that was viewed. There was a significant tendency for people to give a time-moving response orientation to the atmospheric disturbance depth cue and a tendency for people to give an ego-moving orientation to the linear perspective depth cue across the two conditions. There were no significant correlations between the ZTPI and any of the depth cues or conditions. These results suggest that the temporal perceptions of time in relation to depth cues are distinct from linear perceptions of time.Psycholog
Effects of Mortality Salience and Uncertainty on Implicit Attitude Toward Religion
No full textReminders of death and personal uncertainty are so distressing that many individuals turn to religion for protection against the fears these reminders can conjure. To investigate this, the current study compared the effects of mortality salience (MS) and uncertainty salience (US) on implicit attitude toward religion. Differences in effects of MS and US on implicit positive attitude toward religion were predicted. A sample of 45 religious female undergraduates participated. After completing a demographic questionnaire, implicit measures of attitude toward religion were assessed using an affective priming task (APT) measuring reaction times (RT) to word valence classification following religious image primes. Participants then completed a written response to a prompt priming MS, US, or a control topic. A second APT tested changes in implicit attitude toward religion following this manipulation. A mixed ANOVA compared valence biases within repeated measures of APTs, between manipulation conditions, and between ethnicities. Results revealed a significant 4-way interaction between time, word valence, condition, and ethnicity. Results suggest that neither MS nor US induced significant changes in attitude toward religion that would imply greater defense of worldviews (i.e. more positive attitude toward religion) following existential distress.Psycholog
Tertiary Outcome Prediction of the MMPI-2 in Spinal Cord Stimulator Trials
No full textSpinal cord stimulation (SCS) is a promising treatment for chronic intractable pain. For a certain subset of the chronic pain population, it is highly efficacious at reducing pain and increasing quality of life. Presurgical psychological screening (PPS) and selection criteria have been used in the past to exclude patients who are likely to fail SCS treatment; however, PPS and selection criteria for predicting outcome are widely debated. The present study examined MMPI-2 data from 59 patients who underwent SCS trials in an attempt to identify predictive factors for SCS success leading to SCS implant. Scale 4 (Pd) of the MMPI-2 provided the best predictive model, correctly classifying trial outcome for 81.4% of all cases. The present study is first in the literature to indicate the central importance of scale 4 in the prediction of SCS trial outcome. Future research is needed to confirm the present study’s findings and to continue to identify predictive factors of SCS outcome to improve PPS selection criteria and to aid in the development of appropriate interventions that will lead to better SCS outcomes.Psycholog
