Assessing the Climate-Smartness of Oil Palm Production Systems: A Spatio-Temporal and Carbon Balance Approach
No full textThere have been on-going efforts to implement policy and practices to produce oil palm in a more sustainable way. Under climate change condition, improved policy and management practices must prioritise strategies that address the intertwined goals of mitigation, sustainable production and adaptation, the core pillars of climate-smart agriculture. However, to date, there has been a lack of empirical assessment of climate-smartness across oil palm production systems under current and projected future climate conditions.
This thesis aims to assess the potential climate-smartness of oil palm production systems in Indonesia, the world’s leading producer, which is responsible for over 50% of global palm oil production. A greenhouse gas (GHG) inventory with finer temporal resolution was used to investigate GHG emissions changes under current mitigation strategies using a coarse 500 m-grid across contrasting regions, management types, and soil types. At site-specific level, the APSIM-OilPalm model was employed to simulate the spatiotemporal variability of productivity and carbon balance for characterising climate mitigation and adaptation performance under current soil and management conditions in different oil palm sites. The APSIM-OilPalm model was also used to simulate the climate-smart metrics of various agronomic practice scenarios to identify the most climate-smart practice for oil palm production under a changing climate. The area of study for site-specific simulation is industrial oil palm plantations on mineral soils in non-deforested areas with zero-burning practices.
This study demonstrates a reduced emissions flux over periods and identifies low- and high-emission oil palm areas. Based on site-specific simulation, this study indicates that all observed OP sites act as a carbon sink ranging from –2.09 to –3.86 tCeq. ha⁻¹ yr⁻¹ across different sites, and that 11 of 25 observed oil palm sites have high climate mitigation and adaptation performance, which is indicated by higher carbon sink values, yields and soil organic carbon increment. The study demonstrates that irrigation emerges as the most climate-smart practice for oil palm production systems under climate change. A higher projected temperature, along with site-specific higher nitrogen fertiliser and lower plant density, decrease the climate-smartness of oil palm production systems.
This study suggests that the climate-smartness of oil palm production systems is viable under current policy and management practices, with additional improvement needed to sustain this under future conditions. This finding provides insight for government to maintain current successful mitigation policy as well as for farmers and industry to monitor targeted management practices that enhance climate-smartness such as maintaining plant density, combatting pests and diseases, and optimising nitrogen fertiliser, as well as prepare for irrigation or water management to adapt to warmer conditions. This ensures meeting the rising demand for palm oil while improving productivity and compliance with global environmental standards
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
