Introduction digital identities, digital ways of living: Philosophical analyses
Full text linkThis special issue seeks to problematize the role of digital technologies in the constitution of the self, taking up the phenomenological premise that experiential structures are shaped and renegotiated through interactions between subjects, environments, and the manipulation of both real and fictional objects. The articles herein address the effects of digital technologies on the human self and, conversely, the active, open, and plastic ways that the self experiences and shapes the digital world. Within contemporary phenomenological debate, macro questions concerning digital technology and identity constitution are increasingly popular topics, soliciting different approaches and theoretical perspectives. With this special issue, we hope to further contribute to this flourishing debate through its three main lines of investigations – corresponding to the three sections into which this issue is organized. We aim primarily to show how digital technologies are re-defining our activities and lives, while also affecting our senses of our identity and selfhood. Each of the three sections analyses interaction between digital technologies and the many layers of self constitution. Section one interrogates the role played by digital technologies in shaping identity. The second section investigates how digital technologies shape our use of language, enabling new forms of communication and social struggle. Finally, the third section explores different ways in which new technologies might affect change in our socio-political world. In this way, the articles collected in this special issue offer an extensive overview of the implications of new technologies in our everyday experience, from the formation of our personal identities to their potential institutional impact
Supply chain finance: The role of credit rating and retailer effort on optimal contracts
Full text linkSupply chain finance aims at finding the best financing arrangements within a given buyer-supplier dyad. The source of capital can be internal (buyer or supplier) or external (financial institution) to the supply chain. So far, many studies have investigated the optimal mix of the sources of capital; our study aims at contributing to the recent literature that explores the interface of operations and finance extending the supplier-based financing models. As the Covid-19 pandemic hits economic activity, the financial constraints have ever greater importance; knock-on effects of the Covid-19 crisis urges on the critical role of a supply chain that should provide financial resources, along to the flow of goods, in the more efficient way. The proposed model considers a supply chain formed by a supplier and a retailer, both capital-constrained that can ask for a loan to a financial institution or resort on their internal reciprocal sources. Demand is uncertain, retailer, that acts as a price taker, may also affect her product demand applying some effort in increasing sales. Both retailer and supplier can fail. The model optimizes the supplier and retailer's’ profit varying their contract parameters; doing this, the research allows to understand the interplay between supply chain operational and financial issues when retailer's sales effort is at work, and its findings can support retailer in the suppliers selection basing on their credit rating. Our findings show how operational (retailer's effort) and financial (trade credit conditions) issues can synergically interact also in supply chain with low working capital or conversely how retailer with high working capital can perform better working with low rating supplier, however boosting the chance to successfully compete in the Covid-19 pandemic era

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
