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
Global Supply Chains, Disasters and Externalities
No full textSprawling and global supply chains are doing a decent job of providing consumers with inexpensive and timely products. However, their size, complexity and lack of accountability make them originators of serious risks and disruptions. Such disruptions are not contained to the closed systems of the respective supply networks, but bleed over into society and the surrounding communities as negative externalities. Consequently, modern supply chains can expect to be subject to greater scrutiny and pressures to reduce risks and provide compensation for the costs imposed on others involuntaril
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
Supply Chain Risk Management in India: An Empirical Study of Sourcing and Operations Disruptions, their Frequency, Severity, Mitigation Methods, and Expectations
Get PDFWith an annual growth of almost 20% since the year 2000, Indian merchandise exports exceeded 300 billion U.S. dollars in 2012. The country is becoming a major supplier to the world. However, companies sourcing products and operating in India are experiencing a variety of supply chain disruptions that impede their operations and finances. The purpose of this dissertation is to investigate the frequency, impact and severity of supply chain risks experienced by companies in India, as well as assess the usefulness of mitigation methods and enquire about future expected disruptions. It is hoped that the results will prepare managers to better prioritize their supply chain risk management efforts and investments. The scope of this study is upstream (sourcing and operations) disruptions that affected Indian supply chains over the past three years, including the areas of logistics and transportation. The methodology is a quantitative, empirical study, using a survey instrument in the form of a questionnaire distributed electronically to thousands of members of four prominent trade associations in India. The platform for the questionnaire is a modification of a traditional risk analysis progression: mapping, identifying, assessing, mitigating and improving, also dubbed MIAMI .
The main findings are that there are major and significant differences in severity (frequency and impact) between the thirteen risk categories presented. There are also significant group differences among the respondents. Traditional mitigation methods differ with respect to usefulness, and expected risks are somewhat different than past risks. Conclusions reached are that chronic risks such as inadequate transportation, logistics and utilities infrastructure, supplier and labor problems, and bureaucracy/red tape are more severe than highly publicized and visible risks such as natural disasters, terrorism and crime. Traditional mitigation methods are useful for many of the disruptions, but ineffective for non-physical risks. There is a certain optimism with respect to future infrastructure related disruptions.
Limitations of the study include a relatively low response rate, the classic difficulty in risk analysis of comparing and scaling the impact of disruptions, and that it is not fine grained enough to fully describe any specific industry sectors. This study contributes to the field of supply chain risk management by adding crucial empirical information from a heretofore unexplored market
A Look at What Drives Export Growth: The Possible Effect of Trade Promotional Efforts and Free Trade Agreements
No full textThis paper challenges the assumptions that governmental trade promotional efforts and the entering into of Free Trade Agreements (FTA’s) have a strong positive effect on U.S. exports. While determining that global economic growth and the dollar exchange rate are the main drivers of exports, the paper uncovers some very interesting and not well known facts about export performance with the seventeen partnering FTA countries. For the U.S. to enter into an FTA does not necessarily cause a surge in exports and imports. This paper cautions against over-optimistic and wholesale attempts to force through controversial FTA’s when perhaps the membership in the World Trade Organization is sufficient to ensure steady growth. It is especially disappointing to see the relative lackluster growth in exports after the NAFTA and CAFTA agreements went into place. Other FTA partners show a much better record
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
