TECHNICAL EFFICIENCY OF CONTAINER TERMINAL OPERATIONS: A DEA APPROACH
Get PDF Nowadays, transporting cargoes via container are key indicator for every shipment. The movement of container involves multi modes to reach destination. The efficient transport networking systems are determinant attribute towards container terminal in providing excellent services to their client. The paper focuses on the metamorphosis of the terminal efficiency and container movements at 6 major container terminals in Peninsular Malaysia. The aim is to measure efficiency of container terminals that contributes significant economic development for a nation. Non parametric approach under frontier method is used to analyse panel data from 2003 to 2010 in relation with container terminal equipments and throughput. The result shows no significant relationship between container terminal size and efficiency. Thus, efficiency is determined from allocation of resources efficiently by terminal operators and not by size of terminals.DOI: 10.12660/joscmv6n2p1-19URL: http://dx.doi.org/10.12660/joscmv6n2p1-1
Regression model analysis for vessel service time
Get PDFTurnaround time in port industry portrays the capability and ability of a container terminal port in providing shipping services. This study is motivated by the rapid development in container terminal ports to provide efficient and effective services and high port productivity. The aim of this research is to develop mathematical relationships between port throughputs and port facilities. Presently, the factors that influence the performance of a port in terms of turnaround time are still debatable. This research proposes a regression model that relates the turnaround time and the port facilities. Two ports in Port Klang, i.e. the Westport and the Northport, were selected as the studied subjects from which the actual vessel call data were collected. A one - month data were used in the analysis. The overall results showed that the vessel turnaround time is highly correlated with crane allocation, number of containers loaded and discharged. The model relating these variables is in the form of multiple regression. The benefits of such a model include that of giving port operators the opportunity to determine optimum crane allocation in order to achieve the desired turnaround time given the quantity of containers to be processed
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
Malmquist Productivity Index for Container Terminal
Get PDFThe current decade sees significant growth in worldwide seaborne container transportation and with it an essential need for optimization of its productivity. Container ports and their terminals are required to remain competitive and able to handle the anticipated growth as there are huge challenges to increase its productivity, to reduce the spatial pressure and terminal congestion. The paper aims to analyse and measure the productivity of major container ports in Peninsular Malaysia. A non-parametric technique is employed to analyse and measure Malmquist productivity in estimating the utmost productive container terminals. The malmquist productivity results replicate the actual container ports productivity in line with resources within container terminals and obtained throughput. It is prove that current container terminals expansion by port operators in line with future demand. Keywords: Container terminal, DEA, Malmquist Productivity Inde
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
