Reallocation Effects of COVID-19 in Venture Capital
No full textResearch indicates that the shock of the global pandemic of COVID-19 during 2020–2023 led to significant reallocations of capital across markets and sectors of economic activity. The shock generated both winners and losers even though these might be offset in the aggregate. This entry discusses the reallocation of financial capital that took place in the venture capital (VC) industry worldwide during the turbulent times of COVID-19
Do banks price discriminate spatially? Evidence from small business lending in local credit markets
No full textIn this paper we explore the effects of bank–borrower physical proximity on price and non-price aspects
of small business lending in local credit markets. Along the price dimension, our analysis reveals that
interest rates increase with bank–borrower distance and decrease with the distance between borrower
and other competing banks. Along the quantity dimension, we observe that more distant borrowers
are more likely to experience binding credit limits. We also show that the quantity effects of bank–borrower distance are concentrated among less transparent firms. Our findings are consistent with pricing
based on marginal costs that reflect information-based factors, and are in contrast to the established paradigm, where banks adopt spatial discriminatory pricing rules when lending to small-sized enterprises
Collateral and local lending: Testing the lender-based theory
Full text linkIn this paper we empirically test the recent lender-based theory for the use of collateral in bank lending. Based on a proprietary dataset of loan contracts written by a local bank in competitive credit markets, we use the physical proximity between borrowers and the lending branch of the bank to capture its information advantage and the magnitude of collateral-related transaction costs. Overall, our results seem more consistent with several classic borrower-based explanations rather than with the lender-based view. We show that, conditional on obtaining credit from the local bank, more distant borrowers experience higher collateral requirements and lower interest rates. Moreover, competitive pressure from transaction lenders does not magnify the importance of lender-to-borrower distance. Our findings are also obtained with estimation techniques that allow for endogenous loan contract terms and joint determination of collateral and interest rates
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
