Analysis of the competitiveness of Indonesian palm oil and cocoa export commodities: a study on Malaysia and Singapore export markets
No full textThis research aimed at analysing competitiveness of Indonesian palm oil and cocoa export
commodities to Malaysia and Singapore markets. The two commodities were selected on
the basis that they are Indonesian main export commodities, which contribute considerably
towards the national income. Despite the significant contributions of the two commodities,
the reality proves that Indonesia is still not able to optimise the potency and increase the
competitiveness of those export commodities. Revealed Comparative Advantage (RCA)
was employed as the competitiveness analysis method by using data in the period of 2009-
2013. Results of the analysis revealed that Indonesian palm oil commodity has a strong
competitiveness in Malaysia and Singapore export markets, as indicated by RCA index,
which is greater than one (RCA>1). Similarly, cocoa commodity also demonstrates a strong
competitiveness since its RCA index value is greater than 1 (RCA> 1) in Malaysia and
Singapore export markets. However, the upward trend of the price of palm oil and cocoa
commodities in the international market is not accompanied by the rise in the export product
value. As a result, Indonesia is still not able to gain benefits from this condition. Moreover,
the change in the internal policy of export destination countries continues to restrict the
import of palm oil and cocoa commodities and this has become a challenge for Indonesia
in order to boost the competitiveness of both commodities in the future
The ARIMA model for the Indonesia stock price
No full textPrediction of stock price volatility is an important topic either in economics or in finance as it benefits both the investors and economists. In this paper, we conducted the prediction of Indonesia stock price by using Autoregressive Integrated Moving Average (ARIMA). The ARIMA model was chosen as the model to predict the volatility of Indonesia stock price due to its simplicity and wide acceptability. To this end, the daily Indonesia Composite Stock Price Index (CSPI) in the period January, 4th 2010 until December, 5th 2014 was employed. This study reports empirical evidences that ARIMA models are applicable for forecasting Indonesia stock price. Furthermore, the results obtained in the study revealed that ARIMA model has a strong potential for short-term prediction and can compete favourably with the existing techniques for stock price prediction. The best ARIMA model was selected using Akaike Information Criterion (AIC) criteria and it was found that ARIMA (0,0,1) is the best model for forecasting the Indonesia Composite Stock Price Index
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
