Impact analysis of forest and peatland landscape change: Socio-economic and environmental implications
Full text linkBackground: Peat forest land is highly susceptible to burning and releasing stored carbon and greenhouse gas emissions into the earth's atmosphere when its water content is used for plantations, agriculture and other uses. This study was conducted to analyze the progress of forest and peatland landscape development in Katingan District, Central Kalimantan Province and its potential ecological impacts on the environment. Methods: This research approach uses a quantitative approach to analyze landscape changes that occur within five years, namely in 2015 and 2020. The research was conducted by examining secondary data only. Finding: The results of this study show that the contrast in land increase between forest and peat land and non-forest land is not significant, as shown by the ratio of forest and peat land/non-forest land which increased by only 0.02 or 2% between 2015 and 2020. If the area of non-forest land continues to increase in the future, Katingan Regency is predicted to have a higher vulnerability to natural disasters. Conclusion: The results of land cover/landscape change in Katingan District, both forest and peatland (consisting of primary dry forest, secondary dry forest, secondary mangrove, swamp, swamp scrub, and secondary swamp forest) and non-forest land, both increased in area, respectively by 26,532.61 ha and 4813.64 ha from 2015 to 2020. Novelty of This Study: This study provides a unique perspective on the ecological impact of land cover changes in Katingan District by analyzing a five-year landscape transformation using a quantitative approach

Energi terbarukan: analisis kebijakan pemanfaatan biodisel kelapa sawit sebagai bahan bakar nabati nasional di tengah kontroversinya sebagai faktor pendorong deforestasi
Full text linkoai:ojs2.journal-iasssf.com:article/543Background: In the midst of the controversy over bioenergy or biofuels as a driving factor for global deforestation, Indonesia is dependent on its palm oil commodities which have been built for years and consume millions of hectares of land. Indonesia's dependence on these commodities to meet domestic and foreign markets is regulated by the biodiesel policy or ESDM Ministerial Decree No. 12 of 2015 concerning the Provision, Utilization and Trading Administration of Vegetable Fuels (Biofuel) as Other Fuels, which states that the use of biodiesel levels in the future will continue to increase, from B20 to B30, then to B40 and so on. However, to be able to meet these policy targets, there is a risk of land clearing. This policy paper discusses what important issues from an economic, social and environmental perspective are related to the development of the palm oil biodiesel industry in Indonesia and what needs to be prioritized in determining future government policy to ensure that sustainable development can be pursued and emission reductions reach targets. Methods: The research method used in this paper is a qualitative approach and descriptive analysis of data collected from literature study. Findings: Apart from that, there are various issues regarding palm oil management, both from a social, economic and environmental perspective, that still need to be addressed, considering that Indonesia is internationally committed to reducing its greenhouse gas emissions by 30% by 2030. Conclusion: Overall In short, there are five recommendations for palm oil biodiesel policy for the future, namely: 1. There is a need for clear data that can support policy decision making; 2. Indonesia needs to evaluate fossil fuel subsidy policies from developing countries that have succeeded in developing their renewable energy sectors; 3. There is a need for intensification, technological improvisation and sustainable agricultural practices on existing oil palm plantation land to meet national bioenergy needs; 4. Prioritizing collaboration between sectors in developing the industry; and 5. The government must be firm in determining a consistent future palm oil biodiesel policy so as not to harm many parties

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
