    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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

    Klasifikasi Perairan Laut Dangkal Menggunakan Citra Sentinel 2-A Berbasis Google Earth Engine di Pulau Payung, Kepulauan Seribu

    Sebagai negara kepulauan, potensi Indonesia di bidang kelautan dan perikanan sangat luar biasa. Secara ekologis, perairan laut dangkal memiliki peranan penting dalam ekosistem laut, baik secara langsung maupun tidak langsung dalam keberlangsungan hidup biota laut. Habitat perairan laut dangkal menjadi tempat berlindung dan tinggal bagi beberapa jenis spesies. Penelitian ini bertujuan untuk mendapatkan informasi habitat bentik di Pulau Payung, Kepulauan Seribu, serta mengevaluasi tingkat akurasinya. Survei dilakukan pada 12-14 Juni 2024 di Pulau Payung dengan pengambilan titik koordinat sebagai data lapangan. Penilaian akurasi dilakukan menggunakan confusion matrix. Algoritma Random Forest dan Support Vector Machine menghasilkan empat kelas habitat bentik, dengan dominasi kelas lamun. Hasil uji akurasi menunjukkan bahwa algoritma Random Forest memiliki tingkat akurasi sebesar 92,85%, sedangkan Support Vector Machine sebesar 85,70%. Hal ini membuktikan bahwa algoritma Random Forest lebih unggul dibandingkan Support Vector Machine dalam klasifikasi habitat bentik. Penelitian ini memberikan informasi penting bagi pengelolaan sumber daya laut, terutama dalam upaya konservasi dan deteksi perubahan lingkungan secara berkala

    PERCEIVED USEFULNESS SEBAGAI VARIABEL INTERVENING PADA KUALITAS SISTEM INFORMASI DAN KEPUASAN PENGGUNA

    Get PDF
    Penerapan sistem informasi akuntansi bisa dengan membangun sistem dari awal atau dengan membeli program akuntansi yang sudah jadi. Keduanya mempunyai kelebihan dan kekurangan masing-masing. Dari sinilah timbul penelitian tentang keberhasilan sistem informasi yang dipelopori oleh Delone dan McLean (1992). Pengkajian penelitian-penelitian sebelumnya tidak ditemukan apakah perceived usefulness merupakan variabel intervening atau bukan. Dengan demikian, tujuan penelitian ini adalah untuk menguji pengaruh perceived usefulness sebagai variabel intervening pada hubungan kualitas sistem informasi terhadap kepuasan pengguna akhir perangkat lunak akuntansi yang belum pernah diteliti sebelumnya. Sampel penelitian diambil dari pengguna MYOB Accounting Software dengan jabatan minimal supervisor dan telah menggunakan MYOB minimal 1 tahun sebanyak 46 sampel. Untuk analisis data digunakan analisa jalur dengan dengan bantuan script uji sobel SPSS 21 dengan bootstrapping 1000 kali. Hasil penelitian berhasil menunjukkan bahwa perceived usefulness memediasi hubungan antara kualitas sistem informasi terhadap kepuasan pengguna akhir perangkat lunak akuntansi.
