Kementrian Pendidikan Nasional yang dibantu oleh Badan Akreditasi Nasional Sekolah Menengah (BAN-SM) memberikan pengkategorian yang terdiri atas kategori A artinya sangat baik, B artinya baik dan kategori C artinya cukup. Adapun komponen yang mempengaruhi antara lain , (1) standar isi, (2) standar proses, (3) standar kompetensi lulusan, (4) standar pengelolaan, (4) standar pendidik dan tenaga kependidikan, (5) standar sarana dan prasarana, (6) standar pengelolaan, (7) standar pembiayaan dan (8) standar penilaian. Setiap komponen/ faktor ada yang memberi pengaruh dominan diantara yang lainnya. Untuk itu perlu dimodelkan dengan Model RLOTG yang merupakan model gabungan antara Model Regresi Logistik Ordinal dengan Model Regresi Terpengaruh Wilayah. Model ini adalah analisis hubungan antara peubah respon dalam kategori ordinal dengan peubah prediktor dengan mempertimbangkan titik lokasi pengamatan dari setiap observasi. Selanjutnya menentukan faktor-faktor RLOTG yang mempengaruhi tingkat akreditasi pada setiap SMA/MA di Provinsi Jambi dan dilanjutkan mendeskripsikan peta keragaman spasial dari setiap peubah, koefisien peubah yang nyata pada akreditasi SMA/MA se Provinsi Jambi.Hasil penelitian memberikan gambaran bahwa semua peubah preiktor berpengaruh secara nyata pada tingkat akreditasi sebuah sekolah. Model RLOTG yang dihasilkan sudah cukup baik, dengan nilai likelihood G=20.61 dan ketepatan klasifikasi menggunakan uji CCR senilai 94%.
 
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
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
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
Model Pembelajaran Berbasis Proyek pada Mata Kuliah Metode Optimisasi di Program Studi Matematika Fakultas Sains dan Teknologi Universitas Jambi
Full text linkThis study aims to confirm the effectiveness of implementing the project-based learning (PjBL) model. The results of this study show that applying the PjBL model to the optimization method course has efficacy in terms of positive responses to learning participation according to the outcomes that need to be met at each meeting increase. As many as 100% of student studies show that learning a musical instrument in the form of materials and task plans can stimulate learning and curiosity in students. Additionally, 98% of students said they were delighted with the project assignments, and 2% said they were burdened with their tasks. Ninety percent of students said group work helped them complete a particular project, and 5% of students said they disagreed with their group assignments. In addition to the questionnaire, the effectiveness of implementing the PjBL model can be seen from the written exam results and the given project assignments. These are cumulative to the final value of the optimization technique course. That means 71% of students get an A. 17% A- and 10% B+. The value indicates that the optimization techniques course is very successful, and no student fails while working with the PJBL mode
