An Analysis on the Growth and Financial Feasibility of Shorea Ovalis and Shorea Balangeran Plantation Forest with Restoration using Indonesian Silvicultural Systems as a Model for Sustainable Natural Forest Management in East Kalimantan Province
Get PDFThis research aims to analyze (1) the growth and distributions of stand diameter and (2) to analyze the financial feasibility of dipterocarp plantation forest restored using Indonesian Silvicultural Systems as a model for sustainable natural forest management (SNFM) in East Kalimantan, located exactly at PT Balikpapan Forest Industry, applying the theory of production to estimate the increment and basal area while the financial feasibility was analyzed using Net Present Value (NPV), Net B/C ratio dan IRR. This research applied scientific methods and the data were obtained up to ten years and then predicted and simulated up to 50 years. The research findings showed that S.ovalis is harvested for the first time at the age of 35 years with the total volume of 97.31 m3 even though the maximum mean increment is achieved at the age of 45; and subsequent harvests are performed every 15 years. S. balangeran is harvested for the first time at the age of 40 years with the total harvest volume reaching 112.95 m3 although the maximum average increment is achieved at the age of 50 years and subsequent harvests are performed in every 20 years. Restoration using Indonesian Silvicultural System Model has more comparative advantages compared with other natural silvicultural system. This model is more productive, having shorter cutting cycles, more profitable, having clearer analysis on its ecological growth. The result of financial analysis using Net Present Value, Net B/C and IRR model proved that S. ovalis and S. Balangeran were feasible to cultivate because the values of their IRR was higher than the value of their MAR. Keywords: Restoration, Increment, Finance, Dipterocarp
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
KAJIAN PERTUMBUHAN RESTORASI MANGROVE PADA KAWASAN TAMAN NASIONAL KUTAI KALIMANTAN TIMUR
Get PDFPenelitian ini dilaksanakan di kawasan Taman Nasional Kutai (TNK) Provinsi Kalimantan Timur. Tujuan dari penelitian ini adalah Mengetahui laju tingkat pertumbuhan tanaman pada lahan restorasi mangrove di TNK, Mengetahui hubungan kualitas lahan restorasi dengan laju pertumbuhan tanaman pada lahan restorasi mangrove di TNK, Mengetahui faktor tempat tumbuh yang berpengaruh nyata terhadap laju pertumbuhan. Lokasi penelitian terdiri atas 4 (empat) Stasiun Pengamatan yakni Stasiun Pengamatan I dan II berada di Kota Bontang dan Stasiun Pengamatan III dan IV berada di Desa Sangkima Kabupaten Kutai Timur. Penelitian ini merupakan kombinasi antara penelitian menerangkan (explanatori research) dan penelitian deskriptif (deskriptif research). Penelitian yang bersifat menerangkan adalah penelitian yang menyangkut pengujian hipotesis. Hasil penelitian ini dapat disimpulkan sebagai berikut: Pemilihan lahan restorasi sebaiknya di sesuaikan dengan jenis yang sesuai dengan tempat tumbuh. Laju bertumbuhan tanaman dipengaruhi oleh pemilihan tempat tumbuh dan terlindung dari kuat arus. Dari hasil penelitian di beberapa stasiun, kegiatan restorasi yang di lakukan di TNK sebagian tidak sesui dengan jenis tempat tumbuh tanama
