Linking Agricultural Trade, Land Demand and Environmental Externalities: Case of Oil Palm in South East Asia
Full text linkReduction of support measures affecting soybean oil in the major soybean producing countries, as a consequence of WTO rules, coupled with rising demand for palm oil in non-traditional palm oil importing countries may lead to pronounced increases in agricultural land demand for oil palm expansion in Malaysia and Indonesia – two main palm oil producing and exporting countries. However, it is expected that the effects on agricultural land demand and consequently impact upon the environment will depend much on existing governance affecting environmental and forestry management in the two countries. Given the relatively more prevalent policy and institutional failures in Indonesia, it is anticipated that deforestation consequences and open burnings in the country will be stronger, inevitably giving rise to recurring haze externalities in the region. This study employed single and multi-country output supply exogenous policy models with explicit factor markets to examine agricultural land demand-trade linkages in the world vegetable oil markets. Shifts in export demand for palm oil and reductions of support measures affecting soybean production were simulated and effects on land use in Malaysia and Indonesia were observed under varying assumptions of environmental and forestry policy regimes in the two countries. Inferences on environmental effects are also provided.Agricultural trade and environment; Oil palm economy in Malaysia and Indonesia; Oil palm expansion and haze; Transboundary pollution; Policy failures and environmental impacts
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
Impact of atrial fibrillation among stroke patients in a Malaysian teaching hospital
No full text92.8%) while haemorrhagic stroke was uncommon (n=156.2%). Patients with AF had a longer median hospital stay, higher mortality rate and greater functional disability on hospital discharge compared to non AF patients. Conclusion: The prevalence of AF among stroke patients in a tertiary centre in Malaysia was 10.6%. Stroke patients with AF were observed to have a higher mortality rate and disability on hospital discharge
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
