Changes in agricultural diversity in West Kalimantan Province, Indonesia : implications of interregional and intertemporal comparisons using data from regencies and city
Get PDF本稿では、パーム油原料としてのアブラヤシの栽培に大きく依存する農業の構造をもつに至ったインドネシア西カリマンタン州で、栽培作目の多様化により農業多様性を高めていくことが実行可能であるかどうかを検討するために、その準備作業として、アブラヤシ農園の拡大という現象を軸に農業の多様性が現地でどのように歴史的変化を遂げてきたか、その州内の各地域間の異同がどのようであるかについて確認することを目的としている。This study aims to examine the historical changes in "agricultural diversity" in the region and the differences among the various regions of the province based on the phenomenon of expansion of oil palm plantations, so as to consider the feasibility of increasing agricultural diversity in West Kalimantan Province, Indonesia, where the agricultural structure has been heavily dependent on the cultivation of oil palm as a raw material for palm oil, by diversifying the types of crops grown.特集 東南アジアの小規模生産者の経済 : 中長期的環境変化と直面する課題(Special Issue: The economy of small-sized producers in Southeast Asia : mid- to long-term environmental changes and challenges faced)論説(Article)departmental bulletin pape
The Replanting Problems of Plasma Estates in the Indonesian State-Owned Oil Palm Estate: A Case in Sanggau Regency, West Kalimantan Province (<special issue> Political Economy of Oil Palm Plantation Expansion: Actors, Discourse, and Institutions)
No full textAround 1980 the Indonesian government launched a program of oil palm plantation development led by state-owned plantation enterprises with some project finance. The program was named Nucleus Estates and Smallholders (NES) Projects and was funded by the World Bank and Asian Development Bank. In the early 1980s some state-owned enterprises constructed several oil palm estates in West Kalimantan Province under the NES scheme, almost all of which were located in Sanggau Regency. These estates are currently facing replanting problems, since the oil palm trees there are 25 to 30 years old and inevitably less productive. In the estates owned by smallholders, "plasma farmers" who have their estates near the nucleus estates owned by plantation companies, the replanting problems are more serious than companyowned plantations because of smallholders' difficulty with financing. In this paper, the author aims to introduce the results of field research regarding the replanting problems on plasma estates owned by smallholders by focusing on one state-owned oil palm estate in Sanggau Regency. For some years after 2007, the Revitalization Program of Estates was implemented in those estates. The program aimed to subsidize a part of the interest imposed on plasma farmers on loans for the revitalization of their old or damaged estates. The implementation of the program, however, was not smooth. The program was not a success because of the inefficiency of the so-called United Management System as a way to manage plasma smallholders' estates after replanting, and because the loan program for replanting did not take account of the estate owners' financial capacity. Alternatives to the Revitalization Program would be possible if those factors were improved
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
