Exploiting 3D Web to Enhance Online Shopping: Toward an Update of Usability Heuristics
No full textOnline shopping has become a widespread habit for millions of users all over the world. E-stores are very convenient for both customers and retailers, because they are accessible 24/7 from anywhere in the world. However, they also convey relevant drawbacks for both parties: customers can only explore endless grids of flat items, and retailers are likely to struggle to manage and update their e-commerce autonomously. Here we present an e-commerce platform levering on 3DWeb technology that is meant to enhance the sopping experience for customers on the one side, and to retailers to independently operate on their e-store. The experience of user with Hybrid Consumer Interface and the Hybrid Seller Interface were evaluated in two interdependent sessions with representative end users (N = 57 in total). Even of both interfaces are still at a prototypical stage, results from the experimental sessions show promising outcomes
Enhancing shopping experience in augmented reality by customizing product manipulation modalities: A customer experience study
Full text linkIn recent years, Augmented Reality (AR) technology has permeated various domains. This paper focuses on the critical aspect of enhancing customer interaction within AR e-commerce environments by investigating the impact of virtual product size manipulation on usability, user experience, and shopping satisfaction. We tested two manipulation modalities: an unconstrained scaling modality, enabling users to manually adjust product dimensions, and an assisted modality providing automatic 1:1 scaling. Using the Microsoft HoloLens 2 AR headset, we engaged 40 participants with small and large virtual products in shopping scenarios using these two manipulation modalities. Results show that users found the automatic manipulation modality to provide a superior user experience, being more effective, easy, useful, and pleasant when interacting with large virtual products. For small virtual products, they expressed a preference for free manipulation. Customer satisfaction with the shopping experience is positive, however, product size and manipulation modality affect the repatronage intention. The findings offer insights into designing AR e-commerce interfaces, highlighting that providing different manipulation modalities depending on the size of the products allows for enriching the shopping experience andimproving the AR market potential
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
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
