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
Insecurities of the old and marginalized : Inflation, Oil Shocks, Financial Crisis and Social Security
Full text linkThe paper examines the impact of recent inflation and financial shocks on the vulnerable, and explores policy design to reduce both future shocks and vulnerability to shocks. Inflation affects the typical savings cum pension portfolio and the specific consumption basket of the old, as prices of services rise compared to manufactured goods. Money illusion and habit, which tend to increase with age, aggravate the psychological trauma associated with inflation. The decline of traditional sources of social security marginalizes those without savings, in the context of sustained ruralurban and international migration. Trends determining inflationdomestic and global, institutional change, and greater openness explain why inflation has been moderate in India, compared to other emerging markets. Since the polity is averse to high inflation, and commodity price shocks are moderating, high inflation will not persist. But the shocks demonstrate the importance of food price inflation for aggregate inflation in populous South Asia. Therefore improvements in agricultural productivity, with supportive buffer stock, fiscal and monetary policy are critical to lower the level of chronic inflation. Regulatory changes to reduce excessive risktaking in financial markets and the aggravation of inflation from speculation are examined. Finally, other policy measures to improve security for the old and keep them an active, vital part of the community are drawn together.Aged, inflation, Oil shocks, financial crisis, social security
Data and Definitions : Underestimating Savings and Investment in an Open Economy
Full text linkThis note clarifies definitions and derives from first principles the relationship between investment, domestic and foreign savings in order to show that there is underestimation of investment and foreign savings given conceptual macroeconomic definitions and Indian practice. Indian national accounts report and use gross domestic savings but the measure of capital inflows used with it is the one appropriate for gross national savings. The degree of underestimation is shown using recent data and implications drawn from the errors.gross domestic and national savings, capital formation, national accounts
Incentives from Exchange Rate Regimes in an Institutional Context
Full text linkIn a simple open economy macromodel, calibrated to the typical institutions and shocks of a densely populated emerging market economy, it is shown that a monetary stimulus preceding a temporary supply shock can abort inflation at minimum output cost, since of the appreciation of exchange rates, accompanying a fall in interest rates and rise in output. Analytic results obtained for two periods are generalized through simulations and validated through estimation. The results imply that one instrument can, in these conditions, achieve both domestic output and exchange rate objectives, since it creates correct incentives for foreign exchange traders who make profits in supporting the policy. Such a policy response is compatible with political constraints; it also imparts limited volatility to the nominal exchange rate around a trend competitive rate, thus encouraging hedging and deepening markets. But strategic interactions imply the optimal policy need not be chosen; supporting institutions are required to coordinate monetary, fiscal policy, and markets to the optimal equilibrium. The analysis gives useful degrees of freedom for Asian emerging markets migrating to exchange rate regimes compatible with more openness.Emerging market economy, Mundell-Fleming, monetary policy, FX market, supply shocks
