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
Analisa Komparatif Portofolio Investasi Syariah Terhadap ROA Asuransi Syariah Di Indonesia Dengan Ukuran Perusahaan Sebagai Variabel Moderasi
No full textPenelitian ini bertujuan untuk menganalisis efektivitas alokasi portofolio investasi syariah terhadap profitabilitas (Return on Assets/ROA) perusahaan asuransi syariah di Indonesia, serta menguji peran ukuran perusahaan sebagai variabel moderasi. Instrumen yang dianalisis meliputi Surat Berharga Syariah Negara (SBSN), Sukuk Korporasi, Deposito Syariah, dan Reksadana Syariah. Penelitian menggunakan data sekunder dari 14 perusahaan asuransi syariah yang terdaftar di OJK periode 2019-2023, mencakup fase pra-pandemi, pandemi COVID-19, hingga pemulihan ekonomi. Melalui pendekatan kuantitatif dengan teknik analisis Regresi Data Panel (Fixed Effect Model) dan Moderated Regression Analysis (MRA), hasil penelitian menunjukkan bahwa secara parsial, hanya return Deposito Syariah yang berpengaruh positif signifikan terhadap ROA, yang mengindikasikan karakteristik defensif instrumen ini dalam menjaga stabilitas laba. Sebaliknya, return SBSN dan Sukuk Korporasi berpengaruh negatif signifikan, sedangkan Reksadana Syariah tidak berpengaruh signifikan. Temuan penting dari uji moderasi membuktikan bahwa ukuran perusahaan memperkuat pengaruh return instrumen berbasis obligasi (SBSN dan Sukuk) terhadap ROA, namun memperlemah pengaruh return Deposito dan Reksadana. Hal ini mengimplikasikan bahwa perusahaan berskala besar memiliki keunggulan kapabilitas manajemen risiko dalam mengelola instrumen kompleks, sementara efektivitas instrumen likuid seperti deposito cenderung berkurang seiring membesarnya skala perusahaa
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
DAMPAK TATA KELOLA (CORPORATE GOVERNANCE), KARAKTERISTIK SPESIFIK PERUSAHAAN, FREE CASH FLOW (FCF) TERHADAP KEBIJAKAN DIVIDEN DI INDEKS LQ45 PERIODE 2018 – 2023
Full text linkPenelitian ini bertujuan untuk menganalisis dampak tata kelola (corporate governance), karakteristik spesifik perusahaan, free cash flow (FCF) terhadap kebijakan dividen di indeks LQ45 periode 2018 – 2023. Metode analisis data yang digunakan dalam penelitian ini adalah regresi data panel, yang merupakan integrasi antara data cross-sectional dan time-series (pooled least square.). Hasil penelitian menunjukkan Tata kelola perusahaan yang tercermin melalui struktur kepemilikan yaitu kepemilikan manajerial berpengaruh negatif dan signifikan terhadap dividen payout ratio, sedangkan kepemilikan institusi dan individu berpengaruh positif dan signifikan terhadap kebijakan dividen. Sementara itu, kepemilikan asing tidak memiliki pengaruh signifikan terhadap kebijakan pembayaran dividen. Karakteristik spesifik perusahaan yaitu variabel growth opportunities memiliki pengaruh negatif dan signifikan terhadap variabel dividen payout ratio. Selanjutnya bahwa terdapat pengaruh positif dan signifikan antara firm risk, yang diukur melalui price to earnings ratio (PER), terhadap dividend payout ratio (DPR). Sedangkan, firm size, firm leverage (DAR), profitabilitilty yang diukur dengan (ROE) tidak terdapat pengaruh siginifikan terhadap kebijakan pembayaran dividen. Serta, variabel free cash flow (FCF) tidak terdapat pengaruh siginifikan terdahap dividen payout ratio
Pengaruh Faktor Internal Dan Eksternal Terhadap Profitabilitas Perusahaan: Studi Kasus Pada PT Asuransi Askrida Syariah
No full textPenelitian ini menginvestigasi anomali kinerja keuangan pada PT Asuransi Askrida Syariah, yang mencatatkan peningkatan profitabilitas signifikan di tengah lonjakan beban klaim pasca-pandemi dan spin-off. Tujuan utama studi ini adalah menganalisis determinan profitabilitas (Return on Assets/ROA) melalui faktor internal (Beban Klaim, Pendapatan Ujrah, Biaya Operasional, Hasil Investasi, Zakat) dan faktor eksternal (PDB). Kebaruan penelitian terletak pada integrasi variabel Zakat sebagai dimensi religiusitas dalam model profitabilitas serta penggunaan data terkini pada periode volatilitas ekonomi (2019-2024). Menggunakan metode kuantitatif dengan data sekunder time series triwulanan dan analisis regresi linier berganda, hasil penelitian menunjukkan bahwa seluruh variabel secara simultan berpengaruh signifikan terhadap profitabilitas. Secara parsial, PDB memiliki pengaruh positif paling dominan, mengindikasikan karakteristik bisnis yang pro-cyclical dan market-driven. Temuan empiris lainnya menunjukkan bahwa Biaya Operasional berpengaruh positif signifikan, yang mengonfirmasi adanya fenomena Productive Spending. Sebaliknya, Beban Klaim, Pendapatan Ujrah, Hasil Investasi, dan Zakat tidak berpengaruh signifikan. Temuan ini mengimplikasikan efektivitas manajemen risiko underwriting dalam memitigasi gejolak klaim, serta menegaskan posisi Zakat sebagai instrumen kepatuhan syariah (compliance) yang tidak mendistorsi kinerja profitabilitas operasional
