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
TEKNIK RADIOTERAPI 3D-CRT DAN IMRT PADA KANKERPAYUDARA TANPA MASKER TERMOPLASTIK DI RS KEN SARAS
No full textEfriza Nur Romadhoni1), Luthfi Rusyadi 2), Dwi Rochmayanti3)INTISARIRadioterapi merupakan metode pengobatan kanker denganmemanfaatkan radiasi pengion. Teknik IMRT merupakan teknik pemberianradiasi dengan berkas sinar yang tidak homogen bertujuan untuk memperolehdistribusi dosis yang homogen. teknik IMRT menggunakan berkas sinar yangbanyak sehingga dapat mempengaruhi peningkatan dosis rendah pada jaringanparu. Salah satu teknik yang disarankan dalam radioterapi kanker payudaraadalah 3D-CRT. Tujuan penelitian ini adalah untuk mengetahui teknik radioterapi3D-CRT dan IMRT pada kanker payudara tanpa menggunakan maskertermoplastik di RS Ken Saras .Jenis penelitian ini adalah kualitatif dengan pendekatan studi kasus.Pengambilan data dilakukan pada bulan Mei 2019 sampai dengan Juni 2019 dirumah sakit Ken Saras dengan metode observasi, wawancara kepada dokterspesialis onkologi radiasi, fisikawan medis, dan radiografer. Data yang diperolehdari penelitian dianalisis dengan model interaktif, membuat transkrip wawancarakemudian direduksi dan diolah dalam bentuk koding terbuka, disajikan dalambentuk kuotasi dan kemudian diambil kesimpulan.Kesimpulan pada penelitian ini adalah prosedur radioterapi teknik 3DCRT dan IMRT meliputi prosedur administrasi, CT Simulator, Treatment PlanningSystem (TPS), verifikasi dan treatment atau penyinaran. Pada teknik 3D-CRTverifikasi menggunakan CR, treatment dilakukan dengan enam sudut gantry, danalat imobiliasasi yang digunakan adalah breastboard. Pada teknik IMRT verifikasimenggunakan EPID, treatment dengan sembilan sudut gantry, dan alatimobilisasi yang digunakan adalah baseplate, TA0, TA15, bantal B3, ARL, KSB,HGD S, LPEC. Pertimbangan teknik 3D-CRT dapat diaplikasikan pada kasusdengan ukuran scar operasi yang panjang. Teknik IMRT dipertimbangkan padapasien yang perlu dilakukan penyinaran mammaria interna
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
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
