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
Essays on paid, owned and earned media in multimedia contexts.
No full textThe three essays in this dissertation deal with un(der)explored challenges for marketing academics and practitioners concerning varying multimedia contexts, including (yet not limited to) self-selection issues, synergies, mediation effects and consistency issues.
According to Corcoran (2009), marketing media can be classified into three categories. First, paid media are third-party channels that firms/brands pay for to leverage. This category mainly consists of advertising, but also entails, e.g., paid search, display ads, pay per click and sponsorships. Second, owned media are channels that the firm/brand creates and controls, with the firm/brand’s website or brochures as the most common examples. Last, earned media are channels through which consumers and the press share a firm/brand’s content, and speak about brands via word of mouth. These media differ from paid and owned media in that they are entirely initialized by consumers, and thus have to be “earned” by firms/brands. Examples include Facebook comments, Twitter replies, blogs, forums and review websites.
Figure 1 shows how the three essays presented in this dissertation fit into the spectrum provided by the POE (paid-owned-earned) media classification. Essay 1, which has been published in the International Journal of Research in Marketing in December 2014, deals solely with paid media and is titled “Billboard and cinema advertising: Missed opportunity or spoiled arms?”. In this essay, we perform a meta-analytic study on the short- and long-run effectiveness of two smaller, less studied advertising media, i.e. billboards and cinema, for 250+ mature CPG brands. While quantifying the effectiveness of these media using advertising elasticities, we correct for the potential bias in these estimates due to the self-section of brands in their media usage. We do not
only do this for the two small media, but also for four larger, more traditional advertising media, i.e. TV, radio, newspapers and magazines. Furthermore, we look into the possibility of synergy effects between these larger media on the one hand and the small media on the other hand. The results of our analysis show that after correcting for self-selection, which turns out to be highly relevant for drawing appropriate conclusions on media effectiveness for the general population of CPG brands, only TV advertising significantly impacts both sales and market share in the long run. Magazine advertising generally leads to primary-market expansion, but does not induce competitive gain, meaning that it tends to improve sales but not market share. The two small media of interest, i.e. billboard and cinema, are spoiled arms for most mature CPG brands, at least from a sales-response (and market-share) point of view. Although this result is a conservative one for cinema advertising, two remarks need to be made on billboard advertising. First, although billboard advertising is ineffective for an average CPG brand, its long-run effect among the subset of users of this medium is significant. Hence, the (small) subset of brands that makes use of this medium appears well-informed (on average) that this medium works for them. Second, a significant long-run synergy effect exists between radio and billboard advertising, indicating that billboard advertising can be useful if it is used together with radio media. However, brands fail to capitalize on this opportunity as the simultaneous use of both media is rare in our data set.
In Essay 2, titled “Online user-generated content: The (in)consistency among hotel-rating websites”, our research setting switches from paid to earned media. In this paper, we address the issue that the vast expansion of the Internet has created an extensively large set of platforms on which consumers can share their opinions with each other, and that users of these platforms might get lost in the abundance of information at their disposition. In order to provide consumers with advice on whether they should consult multiple rating websites (i.c. hotel rating websites) to obtain a reliable indicator of quality as perceived by their peers or whether consulting one of the more prominent websites suffices, we perform a consistency analysis on 665 Parisian hotels rated on four of the most popular customer review websites – i.e. TripAdvisor, Booking.com, Expedia and HolidayCheck. The according results provide substantial evidence of the high level of consistency among three of these four platforms. It is, however, important to note that the consistency here lies in corresponding rating behavior and patterns, rather than actual rating scores. Consumers are consequently advised to rely on TripAdvisor’s, Booking.com’s or Expedia’s ratings, although the mean of these scores would improve the reliability performance even further. HolidayCheck, in contrast, shows a relatively low level of consistency with the three other websites. As the drivers behind this discrepancy are unclear, further research on this matter might be called for.
While Essays 1 and 2 revolve around multimedia research questions within one media category (i.e., paid or earned media), Essay 3 focuses on a context including two types of media, being paid and owned media. This essay is titled “Media effectiveness in the non-profit entertainment industry”. The objective of this paper is (i) to put in contrast the sales-driving roles of traditional advertising and informational websites, and (ii) to test for a potential mediating or moderating effect of the former media on the latter. We situate this research in a non-profit setting, where marketing accountability is even more pressing than in for-profit industries. Relying on the case of Technopolis, a Belgian science-themed entertainment park, we are able to show how the owned medium, i.e. the informational website, is a much more important attendance driver (and likely at a much lower cost) than both print and radio advertising. As such, our results support the industry claim that owned online media can well become a cost-effective complement for cash-constrained non-profit organizations. Further, our analysis provides no empirical evidence of any mediating or moderating role of print or radio advertising on the consumers’ activity on the informational website. A better alignment of the on- and offline media might thus further improve these media’s effectiveness.
In conclusion, besides the academic relevancy of the provided research, the three essays in this dissertation also provide valuable insights for both marketing managers and consumers. First, the examination of advertising-channel effectiveness in the CPG market gives rise to guidelines on budget allocation for start-ups, while it might urge established brands to reevaluate and possibly rethink their current advertising strategy. Also, it brings to light the opportunity of synergistic effects between radio and billboard advertising. Second, our results on website effectiveness and the lack of evidence for its mediating and moderating effect with more traditional media, shows the high potential effect of online media in the marketing strategy and hopefully might serve as a driver for marketing managers to strengthen the alignment between online and offline media. Last, our third paper shows that consumers can rely on most of the major hotel rating websites and that they should accordingly not have to go through an extensive research process across multiple websites to obtain an adequate representation of quality as perceived by their peers.
The three essays in this dissertation also open up new paths for future research on POE media. For example, given that we could not find any empirical evidence of a general effectiveness of cinema and billboard advertising on sales and market share, it would be interesting to study their effect on mindset metrics, such as brand recognition or liking. Also, it would be interesting to study the exceptional cases in which these small media do tend to be effective, in order to depict common brand or campaign characteristics that are crucial for the success of billboard or cinema advertising. Furthermore, with our results on media effectiveness in the non-profit industry, which deviate from prior results obtained in the for-profit industry, we hope to stimulate further research on this topic. Last, further research is warranted on the consistency subject of online rating websites. For example, it might be interesting to determine the causes of the differences in rating values across different websites, not only in the hotel industry but also beyond.status: Publishe
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
