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
Russian foreign policy in a time of rising U.S.-China competition
No full textMain Argument:
U.S.-China competition has not changed Russia’s foreign policy trajectory during the past decade. Instead, the Russian leadership continues to deepen cooperation with Beijing and push back against Washington. Russia has provided China with strategic support but lacks similar capacity to assist technologically or economically in the Sino-U.S. trade war. Challenges to globalization have only marginally influenced Russia’s capacity to generate national power due to its limited role in the global economy, which is concentrated in a few sectors such as energy and arms. Finally, the Covid-19 pandemic has impeded efforts to improve demographic trends and initially threatened the Putin regime’s legitimacy. The Kremlin, however, has used measures to control the pandemic as an opportunity to consolidate power by pushing through constitutional amendments and cracking down on political opposition.
Policy Implications:
Although Russia cannot be expected to support the U.S. in its competition with China, Russian support for China has clear limits. Moscow is not ready to endorse Beijing’s territorial claims or bid for regional hegemony in East Asia. Russia has been accommodating of China’s growing economic and political influence in Central Asia, but Moscow attempts to maintain the upper hand in the security realm. Thus, the prospect of a revisionist Sino-Russian alliance directed against the U.S. and its allies is unlikely.
Russia will attempt to capitalize on the U.S. preoccupation with China and improve its position globally—in particular in the post-Soviet neighborhood, Europe, and the Middle East.
Whereas deglobalization has not significantly affected Russia, climate change and international efforts to reduce carbon emissions pose serious challenges to the political-economic model built around Vladimir Putin
Leveraging uncertainty: India’s response to U.S.-China Ccompetition
No full textMAIN ARGUMENT: A shared interest in limiting China’s rise has elevated the defense and strategic partnership between Washington and New Delhi and enhanced India’s geopolitical stature as a hub of strategic coordination in the Indo-Pacific. Although the Covid-19 pandemic will depress its medium-term trajectory and exacerbate preexisting challenges, India may yet resume its robust rise with deft policymaking. India is partly pursuing this goal by trying to take advantage of risks to globalization, such as the quest for supply chain resilience among Indo-Pacific countries. Ultimately, however, India’s interests are its own and unlikely to bend significantly in the direction of U.S. interests, absent a shared threat or joint opportunity. POLICY IMPLICATIONS: Washington can expect India’s support in U.S.-China competition, but India will also leverage the current situation to achieve its national interests, which will occasionally clash with those of the U.S. This should not be cause for U.S.-India discord but rather the basis for managing expectations. The pandemic will delay but not derail India’s rise if the government can devise a mix of long-term policies focused on growth, employment, and human development. To this end, the U.S. can further develop partnerships in India’s health sector. India’s efforts at economic self-reliance are an opportunity for the U.S. and its allies to diversify supply chains in the Indo-Pacific. Investing in India’s long-term potential to become a manufacturing powerhouse can only benefit countries looking to reduce their dependence on China
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
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
