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
Land use planning by using ArcGIS software: a case study / Mohammad Anas Azmi
Get PDFLand used planning is a land where it has been used to develop a vegetative area for the economics and social environment. The purpose of using Precision Agriculture was to give benefit for developing the land used planning efficiently by saving the time and operational cost. The purpose of this study is to design the land used that has been identified for development of double stage nursery consists of pre-nursery and main nursery. ArcGIS Software 10.3 has been used in this procedure. This study was conducted at Jasin, Melaka. There are five different designs mapped in the ArcGIS to show the nursery area for pre-nursery, main nursery, road, drainage, store, hut and engine pump water. Then, using ArcGIS features, each area was calculated to estimate the number of polybag needed for each designed. Each designed was evaluated according to the criteria identified in term of the area involved, road accessibility, security, shaped of sub-block division and drainage and irrigation system. Comparison was made between each of the designs based on the score from the weightage value. The designed with highest score was chosen to be applied in the field. In conclusion, technological advancement such as ArcGIS makes farmer’s lives much easier as it can map their field and monitor the production. Thus, Precision Agriculture can be recommended as a better alternative than the existing traditional method
Field performance evaluation of autopilot and manual steering systems operations of a tractor-mounted soil ECa sensor in oil palm plantation / Mohammad Anas Azmi
Get PDFNowadays, the advancement of precision farming continuously reshapes the landscape of agricultural operations productivity. Precision farming gives many benefits to the farmers’ community in managing and monitoring their farmland by using modern equipment and technologies. The autopilot steering system is one of the precision farming technologies in the driving of machinery that has been implemented in modern driving modes of tractors in developed countries. However, further evaluations of this system become a prime interest, especially in regards to its application in the areas which are different from its country of origin. Thus, this study evaluated the operations of tractor-mounted soil ECa sensors with manual and autopilot steering modes on immature oil palm areas. A New Holland TD5.75 tractor with an engine power of 75 horsepower equipped with a Trimble autopilot-automated steering system was used in the study. The tractor pulled a Veris 3100 soil ECa sensor to measure the soil ECa at the study area. A combination of ArcGIS with Microsoft Excel was employed to develop a simple approach for evaluating the straight-line accuracy of the tractor when moving with an autopilot steering system. The results showed that both steering modes generated slightly different patterns of spatial variability on the interpolated soil ECa maps. However, autopilot steering mode consumed lower human energy expenditure of operator at 0.44 kcal/min as compared with the manual steering. Besides that, it also offered a higher effective field capacity of operation with 5.13 ha/h compared with the manual steering. The error in positioning straight-line accuracy of the operation of the tractor-mounted soil ECa sensor with autopilot steering was at average 7.78 cm that indicating an acceptable range of straight-line error. Conclusively, the operation of the tractor with autopilot-steering showed good results to be implemented as an alternative tractor’s driving system for operating the Veris 3100 soil ECa sensor on immature oil palm areas. In general, this technology had a great potential to be introduced in the Malaysian oil palm plantation industry in an effort to enhance the infield operations with the up-to-date technology and create more enjoyable working environments in the plantation
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
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
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
