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
Implementation of Scaffolding Assisted Project-Based Learning Models in Buffer Solution Materials
No full textThis study was conducted to solve of applying the learning model to skills and scientific process results in Buffer Solution learning materials in senior high school (SMA). In the early stages, the researchers designed scaffolding by linking the PjBL Flipped Classroom model, KPS, and buffer solution material. Then, these two products were validated by a team of experts involving scaffolding design validation, flow validation, learning design validation, and material validation to see the suitability of the scaffolding assistance at each stage of the PjBL Flipped Classroom model and the feasibility of the products developed and required to adopt the products produced to the principles set found in learning design. After completing the validation stage, the practitioner validation stage is continued to see the practicality of using the product being developed. Then a small group test is carried out to see the application of the product being developed. The results showed that learning chemistry using the Scaffolding Flow in the PJBL Flipped Classroom model could increase students' chemistry learning activities and outcomes on the concept of buffer solutions
Pengembangan Rencana Pelaksanaan Pembelajaran Berbasis Kearifan Lokal dengan Model Problem Based Learning (PBL) pada Materi Usaha dan Pesawat Sederhana di SMPN Kota Jambi
No full textThis study aims to develop a local wisdom-based learning implementation plan for businesses and simple machines. The lesson plan is a tool used by teachers to carry out learning inside or outside of school. The development model used is the 4D development model, which consists of define, design, develop, and disseminate stages. and disseminate. This local wisdom-based learning tool can be used as a problem context to explore science concepts, especially in junior high schools. RPP media expert validation got a maximum score of 72 out of 90 and was in the interval 76–90 with the category "Very Good" with an average of 4 and a percentage of 80%. And the validation of lesson plan material experts gets a maximum score of 87 out of 100 and is in the interval 88–100 with the "Very Good" category with an average of 4.35 and a percentage of 87%
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
Perkebunan Sawit dari Perspektif Lingkungan dan Sains
Get PDFKajian ini menyajikan analisis kritis terhadap praktik perkebunan sawit (Elaeis guineensis) dari perspektif filsafat lingkungan dan ilmu pengetahuan (sains). Analisis menggabungkan data kuantitatif terbaru mengenai luas lahan, produksi, dan dampak lingkungan, termasuk kaitannya dengan deforestasi dan emisi gas rumah kaca, dengan landasan teoretis seperti deep ecology, ecofeminism, dan etika lingkungan yang relevan untuk memahami dimensi normatif dan empiris dari ekspansi sawit. Metode yang digunakan adalah studi literatur kritis, sintesis data sekunder dari lembaga internasional dan nasional, serta pendekatan analitis interdisipliner. Temuan utama menunjukkan bahwa ekspansi sawit berkontribusi signifikan terhadap konversi lahan dan emisi, tetapi juga memiliki peran ekonomi yang besar bagi negara-negara produsen. Ketegangan antara kesejahteraan ekonomi dan keberlanjutan lingkungan pada negara-negara tersebut menuntut kebijakan berbasis hukum yang lebih tegas, mekanisme tata kelola lahan yang transparan, serta tindakan restorasi pada lahan gambut yang terdampak. Rekomendasi praktis meliputi penguatan regulasi izin konsesi, insentif untuk praktik sawit berkelanjutan, rewetting lahan gambut, serta dukungan pada petani skala kecil untuk transisi ke praktik wanatani dan sertifikasi yang kredibel
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
