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
FINANCIAL VALUE ADDED: SUATU PARADIGMA DALAM PENGUKURAN KINERJA DAN NILAI TAMBAH PERUSAHAAN
No full textOne of alternative concept for measuring financial performance is Economic Value Added (EVA). Beside that a value added-based approach that has not regularly been studied empirically is that using Financial Value Added (FVA). This paper tries to explain in detail how to measure business performance and value added based on FVA related to financial management decisions.
Abstract in Bahasa Indonesia :
Salah satu konsep penilaian kinerja keuangan yang sudah mulai banyak ditelaah adalah Economic Value Added (EVA). Sedangkan Konsep nilai tambah perusahaan yang belum banyak dikaji Financial Value Added (FVA). Paper ini akan menjelaskan secara detail bagaimana mengukur kinerja dan nilai tambah perusahaan berdasarkan FVA yang dikaitkan dengan keputusan-keputusan dalam majemen keuangan. Namun sebelumnya akan dijelaskan pengukuran dengan menggunakan rasio keuangan dan EVA.

Co-integration and Causality Among Jakarta Stock Exchange, Singapore Stock Exchange, and Kuala Lumpur Stock Exchange
No full textFor both risk management and portfolio selection purposes, modeling the linkage across financial markets is crucial, especially among neighboring stock markets. In investigating the dependence or co-movement of three or more stock markets in different countries, researchers frequently use co-integration and causality analysis. Nevertheless, they conducted the causality in mean tests but not the causality in variance tests. This paper examines the co-integration and causal relations among three major stock exchanges in Southeast Asia, i.e Jakarta Stock Exchange, Singapore Stock Exchange, and Kuala Lumpur Stock Exchange. It employs the recently developed techniques for investigating unit roots, co-integration, time-varying volatility, and causality in variance. For estimating market risk of portfolio, this paper employs Value-at-Risk with delta-normal approach.Risk Management, Causality, Co-integration, Stock Markets
Co-integration and Causality Analysis on Developed Asian Markets For Risk Management & Portfolio Selection
Full text linkBoth practitioners and academicians demand a linkage model across financial markets, particularly among regional capital markets, for both risk management and portfolio selection purposes. Researchers frequently use co-integration and causality analysis in investigating the dependence or co-movement of three or more stock markets in different countries. However, they conducted the causality in mean tests but not the causality in variance tests.
This study assesses the co-integration and causal relations among seven developed Asian markets, i.e Tokyo, Hongkong, Korea, Taiwan, Shanghai, Singapore, and Kuala Lumpur stock exchanges, using more frequent time series data. It employs the recently developed techniques for investigating unit roots, co-integration, time-varying volatility, and causality in variance. For estimating portfolio market risk, this study employs Value-at-Risk with delta-normal approach. The results show whether fund managers would be able to diversify their portfolio in these developed stock markets either in long run or short run
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
