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
Coping with the Covid-19 Pandemic: The Plight of Urban Slum Dwellers in Kolkata, India
No full textWe analysed the impact of the COVID-19 pandemic on slum dwellers in Kolkata, West Bengal, using a primary questionnaire-based survey and time use survey of the head of the household and his or her spouse from 252 households, with a total of 504 respondents. The unconditional quantile regression analysis shows that the monthly household income didn’t change significantly during the pre- and post-COVID-19 periods even though there was a slight decrease in the income of male slum dwellers in the post-pandemic period. Second, women’s full-time and part-time employment increased in the post COVID-19 period compared to the pre-COVID-19 era, because women who had not worked prior to the pandemic joined the labour force to maintain their monthly household income. We also conceptualized the “Me-Time” concept, which is the sum of time spent on leisure and sleeping. We used a 70% percent median me-time in the sample data as a threshold for the time poverty line during the post-COVID-19 period. Our findings show that me-time is 48 minutes and 88 minutes less, respectively, for fully employed or partially employed women, compared to their male counterparts. The number of children under 10 years significantly reduces an individual me-time across all employment status subgroups. We also used a time poverty threshold based on the committed time of the respondents, where the threshold is defined as 1.5 times the median committed time in the sample. We observe that 25% of fully employed women are time poor, compared to only 8.3% of fully employed men
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
A theoretical analysis of product versioning in the context of commercial piracy
No full textThe study develops a vertically differentiated duopoly model in the presence
of commercial piracy with two groups of consumers, a business group and a
home group, with the former having higher willingness to pay for the
product. A firm producing an original information good sells it with
endogenously chosen product quality and acts as a price leader, and the
commercial pirate becomes the price follower. There exists a stringent
government policy of monitoring commercial piracy, which increases the
marginal cost of the pirate. We study and compare the two regimes of
no-versioning (selling a single quality product) and product versioning
(selling products with different price and quality combinations to different
consumer groups). In the versioning regime, depending upon demand and
government monitoring parameters, two equilibria are observed. Comparing the
original firm’s profit in each of these versioning cases suggests that
versioning may or may not be the original firm’s optimal strategy in the
presence of commercial piracy. This result is counterintuitive to existing
literature on product versioning in the context of enduser piracy
Export, sssembly-line FDI or FDI with the possibility of technology diffusion: Optimal entry mode for multinationals
Get PDFThe paper tries to evaluate the optimal entry mode of a Multinational Company that is choosing among export, fragmented production structure with assembly-line FDI in LDC or complete production in LDC with FDI. The results show that if the plant installation cost is sufficiently high then the firm will find it profitable to export the finished product to the LDC market and the Government will not exercise any IPR restriction. If plant installation cost is below a certain critical level the MNC chooses complete LDC production with FDI over assembly-line FDI if the IPR restriction is strong, where the model assumes that a fake producer can copy the product if complete production takes place in LDC. In such a situation government will choose to protect IPR if government earning exceeds the cost of IPR protection, otherwise no monitoring is the optimal strategy of the government and MNC will choose the strategy of fragmented production structure and assembly-line FDI will take place in LDC
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
