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
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

Photo manipulation: the influence of implicit visual arguments on dual processing
Get PDFtextIndividuals view an overwhelming number of mediated messages every day, even if most of these messages are merely glanced at or given minimal amounts of attention. It is not possible or advantageous for individuals to critically evaluate all messages they encounter. In that first glance or initial impression, however, our brains process the visual arguments designed by photo manipulation presented in messages. This happens instinctually, almost instantaneously, and most often underneath our radar of consciousness. Following, individuals decide to attend to the information (or not) though conscious processing. Regardless of decisions for elaborative processing, however, the initial visual processing of photo manipulated arguments influences how individuals think, feel, and behave – whether they are aware of it or not. This dissertation contributes to our understanding of the role of implied visual arguments for persuasive message processing in three ways. First, Experiment 1 identified and provided empirical evidence for effects of photo manipulation as a visual persuasion technique. This experiment was a necessary first step in exploring the cause-and-effect relationship of photo manipulation and attitudes to better understand influences on message perception. Second, Experiment 2 tested currently used dual processing approaches for persuasive messages to overcome the gaps that currently exist. Theoretical frameworks widely used in advertising and communication research – ELM and HSM – largely overlook the influence of visual communication and visual processing. These models do not account for the current understand of the brain mechanisms and processes for message processing. Findings from Experiment 2 provide evidence for the need to refine these models to account for influential visual processing variables that are largely absent from the literature. Third, findings from both experiments contributed to the conceptual refinement of visual literacy with evidenced-based support for the boundaries of when this concept is (or is not) influential for assigning meaning to visual messages.Advertisin

Chasing the White Rabbit: seeking clarity and understanding in advertising creativity
Get PDFtextCreativity plays a central role in advertising. From the execution of advertising material to the strategy that drives it and the media used to disseminate it, creativity permeates every phase of the advertising process.
However, the literature regarding advertising creativity is messy and somewhat fractured. As such, Phase 1 of this dissertation will be a scoping review, designed to bring the clarity and insight afforded by a “high altitude” exploration the topic.
Additionally, advertising—in both construction and delivery—has evolved significantly over the last decade as new technologies and new methods for reaching consumers have become available, but relatively few researchers are examining the way advertising creativity is being taught. As such Phase 2 is a qualitative exploration of creative advertising education in 9 top-ranked advertising schools and portfolio programs. Semi-structured interviews were conducted with creative faculty in these programs and were analyzed using thematic analysis. Findings and major themes are discussed, as well as limitations of the dissertation and suggestions for future research.Advertisin
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

The Influence of Video Games on the Mental Health of College Students and Adolescents
Get PDFAs video games experience a rise in popularity, the issues of participating in this hobby become more concerning. For mental health, problems with video games can lead to an exacerbating effect on psychiatric disorders such as anxiety and depression. This thesis gathers sources from across psychology and communication disciplines to determine the effects of video games on the mental health of adolescents and college students. This literature review finds that the effects of video games on the mental health of adolescents and college students are complex. I examined and compared the results of various studies over the last 20 years and offer conclusions and propose solutions to these issues. Using the existing literature, I show that playing video games obsessively can be an issue. However, in the absence of addiction, video games can be used to treat symptoms or aid therapists for mental health issues as they relate to psychiatric disorders. Simply playing video games will generally not affect college students or adolescents negatively. When paired with addiction or obsession, however, video games are correlated with the development of psychiatric disorders. But addiction and obsession are not defined by the amount of time that video games are played. In the case of depression, playing video games through an addiction or obsessively can worsen symptoms or correlate with their development. Some studies show anxiety can be correlated to video game addiction, and others show the opposite result. There is little research in this field of study, and as such, more studies and experiments should investigate this phenomenon. Specifically, research should be done to determine if video game addiction, usage, and psychiatric disorders are correlated and whether video games can be used by health professionals to combat these disorders.Psycholog
