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
Nature and Salient Features of Pakistan's Manufacturing Sector: A Comprehensive Insight: Asad Abbas, Muhammad Ramzan Sheikh
No full textThe study investigates the nature and salient features of Pakistan's manufacturing sector by focusing on the structure, conduct and performance aspects for 2004-2018. In structural analysis, Pakistan State Oil Company Ltd has turned out to be the largest firm according to gross sales criterion while Oil & Gas Development. Co. Ltd is classified as the largest firm according to the total assets criterion. Six industries are categorized as most heavily concentrated industries, five industries are in moderately concentrated industries while four industries are placed in the least heavily concentrated industries according to four-firm concentration criterion while according to Herfindahl-Hirschman Index principle, six industries are characterized as highly concentrated industries, two industries are in moderately concentrated industries while seven industries are placed in low concentrated industries. Demand and market conditions point out the disparity between the own-price elasticity of market demand and the own-price elasticity of a firm's product. In conduct analysis, Learner's index shows that there is imperfect competition in Pakistan's manufacturing sector. The chemicals & Pharmaceuticals industry has come out with high advertising while the Petroleum Products industry has the lowest advisement intensity. In performance analysis, Spinning, Weaving has more gross profit to sales ratio while Electrical Machinery & Apparatus has the lowest gross profit to sales ratio. The Motor Vehicles industry is at the top for Charnes-Cooper-Rhodes (CCR), BankerCharnes-Cooper (BCC) criteria while for scale efficiency, the cement industry stands at the ape
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
Structure-Conduct-Performance (SCP) Paradigm: A VAR and VECM-based Granger Causality Analysis
No full textThis study has focused on Pakistan’s manufacturing sector through the lens of the structure, conduct and performance (SCP) model over the period of 2004-2018. Three types of analyses i.e., SCP paradigm in a VAR framework, SCP paradigm in a Granger causality analysis through VAR framework and SCP paradigm in a VECM framework have been conducted. The pairwise Granger causality shows that there is bi-directional causality between structure and performance, conduct and performance and conduct and structure. The block exogeneity Wald test suggests that one-way causality is in the SCP paradigm. Three-panel cointegration tests i.e., Kao residual cointegration test, Johansen Fisher Panel cointegration test and Pedroni Residual Cointegration test confirm the existence of the long run relationship. VECM-based Granger causality exhibits the long run and short run causality in the SCP approach. The study suggests that all the stakeholders of SCP must formulate their policies by recognizing their mutual interdependence

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
Is There an Arms Race Between Pakistan and India? An Application of GMM
Full text linkThis study employs the Richardson model to investigate the presence of an arms race between Pakistan and India during the period 1972–2010. Using the generalized method of moments approach, we find that the grievance term for the Pakistan model is positive while that for India is negative. Both countries’ defense spending in the previous period is negatively related to the change in their own defense spending due to the economic or administrative incidence of an arms race. Moreover, the defense or reaction coefficients in the specified model determine the presence of an arms race between the two countries. The signs of these coefficients are positive in accord with the classical Richardson model, suggesting that an arms race does indeed exist between Pakistan and India
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
