The use of bamboo slats laminate as a renewable construction material for East Java traditional fishing boat
No full textToday marine fisheries in Indonesia are still mostly carried out using traditional fishing boats. Traditional fishing boats are vessels built from solid teak wood with a capacity of up to 20 GT with manually operated fishing gear. It is estimated that overall the number of traditional fishing vessels reaches 518,746 units operated by almost five million fishermen. In an effort to at least maintain and subsequently increase the number of traditional fishing vessels, the availability of solid wood as a basic material is required. However, nowadays fishermen face the problem of solid wood scarcity as a material for reparations and the construction of new boats. In order to solve this problem, research has been carried out on the use of bamboo slats laminate as a substitute for solid wood. The output of this study shows that the laminated material of the bamboo slats has mechanical properties that meet the classification requirements for ship construction. This material has been applied to traditional 2 GT capacity fishing boats operated in Blitar Beach, East Java. This study shows that lamination of bamboo slats can simplify the process of forming traditional fishing boat scantling elements, speed up production time by 33.33%, and reduce construction costs by 35.05%; smaller size of structural components makes the weight of the structure lighter. So that for the same draft, it will increase payload by 189.35% compared to boats made from solid teak wood. If the payload is considered the same, then this traditional boat made from bamboo laminate can reduce its engine power by 25.7%. Ultimately, the development of laminated bamboo boats is believed to have potential in supporting the business continuity for traditional fishermen at lower levels.</p
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
Organisational challenges in integrating customer collaboration processes and practises in the supply chain
No full textIn this paper, we investigate the challenges of customer collaboration in the context of the supply chain of manufacturing industry. The aim of this case study is to increase understanding of the main organizational problems faced by a main contractor in creating novel customer collaboration practices in the supply chain. Our preliminary results reveal that the enhanced customer collaboration affects the supply chain and the main processes of the main contractor. We argue that main contractors should integrate and update their collaboration processes and practices together with the supply chain for all actors, including customers, to increase the efficiency and customer understanding in the supply chain
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
The Bullwhip Effect in Retail Supply Chains: an Analysis of Stock Ordering Policy And ICT Logistics Systems
No full textDispelling 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
