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
Return Spillover of Asian REITs
Get PDFThis research examines the relationship and direction of return spillover of Asian REITs, between REITs and local stock markets, and its effect towards REIT returns. The samples are from Hong Kong, Japan, South Korea, Malaysia, Singapore, Thailand, and Taiwan. This research uses Diebold and Yilmaz’s technique to measure the relationship and direction of return spillover between asset classes. The method also uses OLS regression to test the effects of return spillover on REIT returns. The results show that connectedness between Asian markets is low. Japan and Singapore are the strongest influencers. Low connectedness was also found between REITs and the local stock market. In general, net return spillover from Asian REIT markets significantly influence REITs’ return. The results imply that the growth of REIT markets depends on the attractiveness of capital markets in a country. Regulators in developing countries need to improve the capital market environment to enable REIT markets to flourish
THE IMPACT OF BOARD DIVERSITY AND THE MODERATION EFFECT OF COVID-19 PANDEMIC ON FREE CASH FLOW
Get PDFIn this study, we propose pandemic Covid-19 as moderating effect on the role of board diversity in enhancing the allocation of free cash flow. The board diversity variables are examined using least squares regression for panel data by exploiting the variables to board gender diversity, board member affiliation, board specific skills, and board size variables for an observation of 279 Indonesian listed firms over the period 2015–2021. We found that the presence of female gender on the board, the presence of board members who have either an industry specific background or a strong financial background, and enough board members deter the opportunistic conduct of managers and likely to reduce excess funds through dividend pay-outs. The results demonstrate that a diverse board reduces agency conflicts and enhances resource allocation supporting governance practices. During the Covid-19 pandemic, the presence of female gender in the board, the presence of boards member with other corporate affiliations, and the adequacy of board size proved to provide more effective supervision of the company's cash flow allocation. The findings are beneficial to policymakers since this explains the significance of implementing measures to enhance the efficacy of the board's role by instituting a diversity requirement
The Effect of Vertical Mergers and Acquisitions (M&A) on the Value of Global Energy Sector Companies
Get PDFThis study aims to analyze the impact of vertical mergers and acquisitions (M&A) on firm value in the global energy sector, distinguishing vertical integration into upstream, downstream, and other categories. The background of this research is that, in the energy sector, most companies tend to acquire target firms operating in the same sector. This study adopts a quantitative approach by collecting data from Refinitiv and S&P Capital. The data consists of energy companies engaged in M&A activities during the 2014-2018 period and evaluates their impact on firm value over five years following the transactions. A total of 443 deals were analyzed using the Difference-in-Differences (DID) method. The results indicate that upstream and other vertical integrations have a significant positive impact on firm value, while downstream vertical integration shows a significant negative impact on firm value
Pengaruh Perencanaan Kedepan Strategis dengan Peran Mediasi Ambidexterity Organisasi dan Inovasi terhadap Kinerja Perusahaan
Get PDFPerencanaan masa depan strategis (strategic forward planning) merupakan proses sistematis yang digunakan untuk menetapkan arah dan tujuan organisasi dalam jangka panjang. Perencanaan ini penting untuk memastikan bahwa organisasi dapat mencapai tujuannya secara efektif dan efisien. Penelitian ini bertujuan untuk mengkaji pengaruh perencanaan kedepan stratregis terhadap kinerja yang dimediasi oleh ambidexterity organisasi dan inovasi. Penelitian ini menggunakan metode penelitian kuantitatif. Data yang dikumpulkan melalui kuesioner. Data yang telah terkumpul kemudian dianalisis menggunakan structural equation modeling (SEM) untuk memeriksa kecocokan keseluruhan model dan menguji bagaimana pengaruh antar konstruk. Data disebar kepada 399 unit kerja teknis dan 144 unit kerja dijadikan sampel penelitian. Hasil penelitian menunjukkan bahwa perencanaan kedepan strategis berpengaruh secara positif dan signifikan terhadap kinerja yang dimediasi oleh ambidexterity organisasi dan inovasi. Lebih lanjut, penelitian ini diharapkan dapat memberikan implikasi dan kontribusi kepada organisasi untuk terus secara fokus dan berkelanjutan untuk menerapkan perencanaan kedepan strategis untuk meningkatkan kinerja organisasi secara terus menerus
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
