Threats or Opportunities? Enhancing Business Performance in the Era of Generative AI
No full textDespite Generative AI’s emerging prominence in the business community, its nascent nature presents uncertainties that impede its broader adoption as a disruptive technology. This paper investigates two pertinent conundrums with theoretical and managerial implications. The first pertains to the potential tension surrounding the adoption of Generative AI: is it financially viable for organizations to adopt Generative AI? Organizations might be reluctant to invest without clear financial benefits. The second concerns the role of complementary assets in amplifying the financial benefits brought about Generative AI. In response to these concerns, we conducted a randomized field experiment with a global online tutoring and learning platform. The study yielded three primary findings. First, we not only find a positive spillover effect of Generative AI on existing services, dampening the concern that Generative AI may supplant a firm’s existing services but also support the presence of complementary assets such as an idiosyncratic proprietary database amplifying the beneficial impact of Generative AI. Second, Generative AI increases advertising impression revenues, an effect that is further magnified when used in conjunction with the unique proprietary database. Third, our analysis shows that these effects are enduring, which implies that the proprietary database is an integral, socially complex, and causally ambiguous resource, instrumental in fostering a sustainable competitive edge. We conclude by affirming that our findings align with and contribute to the resource-based view of the firm and the dynamic capabilities perspective
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
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
A Mixture or a Compound? Community-Level Antecedents of Firms’ Category-Spanning Strategies.
Get PDFThis dissertation examines community-level antecedents of firms’ market diversification and product differentiation strategies using the concept of category spanning. Exploiting novel and extensive data on the restaurant industry in a large metropolitan statistical area, I find a contrasting effect of economic and social status of consumer communities on firms’ market diversification. Results show a negative effect of residents’ income levels and a positive effect of their education levels on the business scope of the restaurants in a focal town. Also, results from a computational text analysis of every word used in the menus of the sample restaurants suggest that it is educated social elites, culturally omnivorous and seeking novelty, who encourage firms to engage in product hybridization. Next, category population is found to have curvilinear relationships with firms’ category spanning. Results suggest that category population has an inverted U-shaped association with firms’ diversification while it has a U-shaped association with product hybridization. Examining the full spectrum of the demand side and the competitive and institutional pressures arising from category population with a novel theory and operationalization of spanning, this dissertation complements the traditional focus in strategy research on the internal determinants of boundary spanning and contributes to understanding sociological and contextual factors influencing the development of firms’ sustainable competitive advantages. The study also has important theoretical and practical implications for questions ranging from the nuanced effects of the demand and competition of local communities on firm strategy to the enduring existence of different types of category spanners.PhDBusiness AdministrationUniversity of Michigan, Horace H.
