EKSISTENSI “BALIHO 2024†DALAM PERTARUNGAN ELEKTABILITAS: ANALISIS PENCITRAAN TOKOH POLITIK
Get PDFFenomena kemunculan media luar ruang berupa billboard dan baliho yang dimunculkan oleh para tokoh politik menjadi perbincangan di ruang publik karena dikaitkan dengan proses menuju Pemilu 2024. Dalam penelitian ini, peneliti melihat eksistensi “baliho 2024†dari empat tokoh politik di antaranya Puan Maharani, Airlangga Hartanto, Agus Harimurti Yudhoyono, dan Muhaimin Iskandar. Tujuan penelitian ini menganilis komunikasi politik dan pencitraan tokoh politik pada perbincangan publik di media massa daring diantaranya Tempo.com dan Kompas.com serta pada hasil pencarian Twitter. Dalam penelitian ini, peneliti menjelaskan tentang distribusi sentimen perbincangan yang hadir di ruang publik, indikator-indikator yang memengaruhi sentimen, serta melihat pengaruhnya terhadap pertarungan elektabilitas antar ke empat tokoh politik tersebut. Metode yang digunakan dalam penelitian ini adalah kualitatif dengan Analisis yang digunakan adalah deskriptif. Sedangkan pemerosesan data melalui software Nvivo 12 Plus. Hasil penelitian ini menggambarkan bahwa sentimen negatif dominan terbangun di perbincangan publik pada pemberitaan dan hasil pencarian Twitter. Dengan indikator tertinggi yakni kemunculan Baliho 2024 dianggap tidak tepat karena dikaitkan dengan kondisi Pandemi Covid-19. Adapun kaitannya dengan elektabilitas, sentimen perbincangan di ruang maya tidak menjadi pengaruh utama dalam pertarungan elektabilitas mengingat adanya kenaikan elektabilitas ke empat tokoh politik tersebut di bulan September dibanding bulan Juni. Hal tersebut juga bergantung pada segmen pasar pemilih yang menjadi target
Multichannel wavefield reconstruction of land seismic data
No full textMultichannel wavefield reconstruction is a technique for reconstructing densely sampled wavefields from a set of sparse measurements and their spatial gradients. Although this concept has proven successful in marine settings, its application to land seismic data remains largely underexplored. In this thesis, I propose a novel acquisition design and a novel reconstruction algorithm to extend the concept of multichannel wavefield reconstruction to land settings. The novel acquisition setup involves deploying pairs of closely spaced receivers to estimate spatial gradients. Conversely, the novel reconstruction algorithm uses the Primal-Dual solver to seamlessly combine a hard data constraint with soft constraints on the spatial gradients and local slopes. A synthetic example demonstrates that the use of a hard data constraint can enhance the overall signal-to-noise ratio and minimize the leakage of weak reflection events compared to a soft data constraint approach. A field experiment demonstrates the feasibility of the proposed acquisition setup, which is shown to allow the reconstruction of dense wavefields from sparsely sampled data. These findings suggest that multichannel wavefield reconstruction is an effective tool for enhancing the efficiency of land seismic acquisition
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
