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
Essays on sticky price models of the international business cycle.
No full textThe first chapter of the dissertation connects two empirical investigations on the issue of which assumption is more appropriate for international business cycle research: sticky export prices or sticky import prices. First, vector-autoregressions demonstrate that in the United States and Canada, import prices tend to react faster to money and exchange rate shocks than the general price level and export prices. The second investigation of the first chapter concerns an important implication of export price stickiness. In an economy with a high level of import penetration, domestic prices should be more responsive to shocks than in a closed economy, due to volatile import prices. Domestic producers find it costly to keep their prices fixed. In the case of fixed exchange rates, on the other hand, import prices are independent of domestic nominal shocks, which makes domestic prices more rigid. Hence, the short-run Phillips curve should be steeper in an open economy with flexible exchange rates, and flatter with fixed rates. A panel version of Ball, Mankiw and Romer (1988) empirical procedure gives support for this implication. This evidence indirectly suggests presence of export price stickiness. The second chapter presents a sticky price dynamic general equilibrium model of a small open economy, which demonstrates several powerful results. The presence of physical capital in the model helps achieve a current account deficit in response to a money shock, which is unusual in the literature, but has empirical support. The trade balance is then found to be countercyclical in the simulated economy, in which the business cycle is driven by either monetary or persistent technology shocks. The nontradable sector in the model helps achieve persistent deviations from purchasing power parity with a high degree of real price rigidity. Likewise, the nontradable sector helps generate overshooting of the exchange rate, which depends on non-separability of labor and consumption, as opposed to the more traditional liquidity effect based overshooting. However, the volatility of nominal or real exchange rates observed in the data can only be reproduced after the introduction of the local currency pricing assumption. Lastly, a virtue of the proposed model is its analytical tractability, which helps develop firm intuition about the model before using numerical solutions.PhDEconomicsSocial SciencesUniversity of Michigan, Horace H.

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
Capital flows, investor behavior, and macroeconomic policy in Thailand and other developing countries.
No full textThe movement of international capital has become a significant concern in many developing countries, especially after the spread of financial crises to many parts of the world. This dissertation examines issues related to capital flows and monetary policy in Thailand and other developing countries. The first chapter of this dissertation focuses on whether these international capital flows destabilized the Thai stock market during the market downturn in 1997. The analysis utilizes vector auto regression analysis, market-timing tests, and correlation tests to examine foreign equity trading in Thailand. The results reveal no destabilizing consequences of foreign transactions; in fact the presence of foreigners in the market helped to cushion the market from a deeper fall in stock returns. The second chapter addresses the effectiveness of policies designed to manage the volume and composition of capital flows in developing countries. The main contribution of this chapter is the compilation of data on policies that affect capital flows collected from various sources. The policy data used here is at a higher frequency and is more disaggregated than data that has been used in the literature to date. Panel data analysis with fixed effect and instrumental variable estimation is used to study the impact of the policy variables on capital flows. The results suggest that the capital flow policies have little effect on the volume of capital flows, but significantly impact the flow composition. The last chapter estimates the Bank of Thailand's monetary policy rules; examining the central bank in responses to inflation and output deviations from target as well as its potential responses to other variables. GMM estimation is performed using monthly data from 1990 to 2001 for the full sample, and 1990 to 1997 for the fixed exchange rate sample. The estimates reveal inflation targeting of the central bank in the full sample period, but there is little evidence of this in the fixed exchange rate period. The central bank's response to output deviations is insignificant. The alternative specifications reveal no evidence of backward-looking behavior but evidence of the bank's response to the variation of the country's terms of trade.PhDFinanceSocial SciencesUniversity of Michigan, Horace H.
