Penelitian Berkelanjutan Dalam Pariwisata Berbasis Alam: Analisis Bibliometrik Dan Visualisasi
Get PDFSustainability, and specifically the need to understand the nature and liminature based tourism of growth, has developed into an important policy issue in tourism literature in the last decade. The objective of the present study is to use a bibliometric approach to review the relevant literature. Bibliometric indicators, such as citations, are used to identify the field structure and the VOSviewer software is used to map the main trends in this area. The bibliometric analysis process comprises three phases: (i) Search Criteria and Source Identification, (ii) software and data extraction, and (iii) data analysis and interpretation.The resulnature based tourism show nature based tourism in full growth as a scientific discipline, thanks to the contribution of various authors, institutions, journals, and related topics that confirm the importance of this field of study. Additionally, bibliometric maps lead to an understanding of the intellectual structure of the subject, in which keyword co-occurrence analysis shows six main themes, ranging from ‘Ecosytem Services’ to ‘Sustainable Tourism’. this, combined with maps of co-citation, broadly exhibinature based tourism this structure and development, showing areas of current interest and potential development, thus offering the latest knowledge nature based tourism research worldwide.  
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
Dinamika kelembaban tanah antar tanaman durian (Durio zibethinus) pada sistem irigasi tetes tanah bertekstur ringan
Get PDFKelembaban tanah permukaan memainkan peran kunci dalam siklus hidrologi karena mengontrol fluks air antara tanah, vegetasi, dan atmosfer. Selain itu, pengetahuan tentang kelembaban tanah sangat dibutuhkan dalam banyak studi pertanian dan aplikasi yang berkaitan dengan pengelolaan irigasi. Sistem irigasi tetes merupakan salah satu alternatif teknologi aplikasi irigasi. Penerapan sistem irigasi ini mampu meningkatkan efisiensi penggunaan air pada lahan kering. Penggunaan air irigasi tetes pada tanaman hanya di sekitar daerah perakaran saja. Tetesan irigasi di daerah perakaran tanaman dapat menekan aktivitas tanaman pengganggu. Kebutuhan air di daerah perakaran berbeda pada setiap tanaman. Komunitas ilmiah telah dengan jelas mengakui pentingnya kelembaban tanah sebagai masukan untuk aplikasi ilmu bumi, mengembangkan pendekatan dan teknik baru untuk pemantauan, pemodelan, dan penggunaan data kelembaban tanah. Pada penelitian ini kebutuhan air irigasi diterapkan pada tanaman durian. Penelitian yang dilakukan bertujuan untuk mengetahui pola kelembaban tanah pada tanaman durian. Kelembaban tanah mempunyai dua pengertian yang berbeda, sebagai kelembaban volumetris (θ) dan kelembaban gravimetris (w). Penentuan besarnya kebutuhan air bagi tanaman secara teliti pada umumnya terbentur pada kesukaran untuk mendapatkan hasil pengukuran yang teliti di lapangan. Kelembaban tanah pada hasil pengukuran berkisar antara 0.228 (cm3.cm-3) hingga 0.699 (cm3.cm-3)

Get PDFAbstrak: Tanah merupakan medium alami untuk pertumbuhan tanaman daratan. Tersusun atas padatan, cairan dan gas. Tanah adalah tubuh alam bebas, tersusun atas bahan mineral dan organik, memiliki lapisan-lapisan yang berbeda dengan bahan induk. Degradasi Daerah Aliran Sungai (DAS) umumnya disebabkan oleh lahan gundul, erosi pada lereng-lereng curam yang digunakan untuk pertanian. Sub DAS Suco masuk dalam DAS Mayang Kabupaten Jember. Sungai Mayang memiliki panjang 24,5 km yang bermuara di Kecamatan Ambulu. Pemilihan sebuah MDS yang representatif dari sifat tanah terpilih menggunakan Principal Component Analysis (PCA). PCA untuk ekstraksi faktor digunakan faktor prosedur reduksi data menggunakan perangkat lunak SPSS 15 (SPSS Inc.). Indeks kualitas tanah disusun berdasarkan nilai pembobot (weighted) yang didapatkan dari pembagian antara % varian dengan % kumulatif. Empat komponen utama dengan enam indikator MDS. Faktor pembobot yang dihasilkan PC1, PC2, PC3, dan PC4 berturut-turut adalah 0,398, 0,258, 0,195, dan 0,148. Penggunaan lahan yang kompleks tersebut memiliki indeks kualitas tanah terendah akibat terletak pada kelerengan tertinggi dengan klasifikasi bergunung. Hal ini memungkinkan terjadinya erosi tanah.Kata Kunci: DAS, Kualitas Tanah, Evaluasi LahanAbstract: Soil is a natural medium for the growth of land plants. Composed of solids, liquids and gases. Soil is a natural environment, composed of mineral and organic material, having different layers from the parent material. DAS degradation generally depends on deforested land, erosion on steep slopes used for agriculture. Suco sub-watershed is included in the Mayang watershed in Jember Regency. Mayang River has a length of 24.5 km which empties into Ambulu District. The selection of an MDS that represents soil properties was selected using principal component analysis (PCA) (Doran and Parkin, 1994). PCA for the extraction of factors used data reduction procedure factors using SPSS 15 software (SPSS Inc.). The soil quality index is arranged based on the weighted value (weighted) obtained from the division between% variation and cumulative%. The four main components with six MDS indicators. The weighting factors produced by PC1, PC2, PC3, and PC4 produced respectively were 0.398, 0.258, 0.195, and 0.148. Land use which has the highest soil quality index in the highest slope with mountainous classification. This allows the use of soil erosion.Keywords: Watershed, Soil Quality, Land Evaluatio
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
