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
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

Get PDFThis report by David A. Robalino, et al. on Pensions in the
Middle East and North Africa: Time for Change evaluates the current
mandatory pension systems formulated in the 1970s in the region. Since
the publication of Boersch-Supan Palacios and Tumbarello (1999), cited
in the volume, the Word Bank has been providing technical assistance to
the countries of the region in the area of pension reforms. According to
Schwarz and Demirguc-Kunt (1999), also cited in the volume, more than 60
countries have introduced pension reforms in the last 20 years. The
financial problems and the fiscal burden of these generous schemes was
the common motivation for the reforms undertaken. The present book by
David Robalino and his co-authors is the extension of those previous
works published five years ago
ESSAYS ON MONEY AND FINANCE: THE CASE OF SELECTED SOUTH ASIAN COUNTRIES
No full textThis dissertation consists of three research studies on capital flows to South Asian countries, estimation of interest rate pass through in Pakistan and the relative city price convergence in Pakistan. The study has used panel data techniques for empirical estimations. The first study attempts to estimate capital mobility in South Asia using saving investment relationship technique and real interest rate differentials methods as suggested by Frankel (1992). The study finds that real interest rate differentials of South Asian countries are stationary and mean reverting with North American, European and Asian countries. Although the RIDS are stationary showing strong evidence of capital mobility, the savings investment correlation is significant. The correlation of savings and investment decreased after 1990s, the post liberalization period implying increased capital mobility afterwards. The RIDs technique provided stronger evidence of than savings and investment correlation technique. The second study is on the estimation of interest rate pass through in Pakistan using two types of data sets i.e. aggregate bank type and retail bank data. The study finds that both lending, deposit and Treasury Bill (TB) rates are non stationary using aggregate data. The lending and TB rate are found to be cointegrated but deposit rate is not found to be cointegrated. The IRPT of four types of banks is found to be less than 1 but three banks showed the IRPT to be higher than 0.5. The highest IRPT is 0.72 in the case of nationalized banks followed by o.70 by privatized banks. The foreign banks IRPT are 0.60. The lowest IRPT is estimated at 0.3. The error correction model estimates overall IRPT to be 0.6 and the convergence parameter is 0.05. It is low and implies that convergence takes time. The study does not find change in 2005 after January 2005 but the speed of adjustment increased when the lending rate is below equilibrium. The retail data provides evidence that lending and deposit rates both are non stationary and cointegrated with TB rate. I found evidence of complete lending rate pass through with Spatial GLS but Phillips Loretain (1991) model shows incomplete pass through. The deposit rate is found to be incomplete and sticky with both the techniques. The third essay provides evidence on relative city price convergence in 35 Pakistani cities with 2 numeraire cities of Lahore and Karachi. The study estimates the autocorrelation coefficient with 2 techniques i.e. OLS and Spatial GLS. Furthermore city wise half life of price shock is also estimated. The empirical evidence supports the hypothesis of convergence in Pakistani cities with both the numeraire cities. The overall half life is estimated to be less than 6 months but there is found heterogeneity in the city wise half life estimates. The half life estimates from Spatial GLS are found to be lower than OLS. The convergence has been found even in the case of distant bordering cities. The overall results support that domestic Purchasing Power Parity holds in Pakistan
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
Impact of monetary policy on lending and deposit rates in Pakistan: Panel data analysis
Get PDFThe study estimates impact of monetary policy (discount rate) on lending and deposit rates in Pakistan using bank type data from November 2001 to March 2011. The study finds evidence of long run relationship between lending and discount rate but deposit rate is not cointegrated with discount rate, monetary policy instrument. The study also finds an increase in the lending rate pass through rate during restricted monetary policy times (2005-2010), whereas deposit rate pass through remains same. The study finds that overall banks pass on only 20% impact of a change in discount rate to the lenders in first month implying it is not complete. There is also significant difference in various bank types pass through rates. The pass through of deposit rate is further low at 0.16 as revealed by short run analysis. It implies that the effectiveness of monetary policy is limited in Pakistan.Discount rate, pass-through, monetary policy
