Preparation of carbon nanotubes by seeded catalyst method using palm oil as starting material / Isrihetty@Siti Salmah Senain
Full text linkCarbon Nanotubes (CNTs) are produced by Thermal Chemical Vapor Deposition (TCVD). The function of support catalyst is to optimize used of the catalyst. The morphology and crystallinity of CNTs produced are determined by Fourier Transmission Infrared Spectroscopy (FTIR). The catalyst was prepared by the sol-gel method with cobalt, iron and nickel as the catalyst where these catalysts were added with different percent of support catalyst. In the synthesizing of CNTs, the palm oil was used as precursor. The collected CNTs are carried out for characterization by using FTIR. Increasing the percent of support catalyst contributes to the unstableness of carbon bonding of CNTs. The CNTs will vibrate more and absorb more energy. In this study, the energy absorbance of CNTs will be varied depends on the catalyst used
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
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
The relationship between information and communication technology and employee's job satisfaction at Pejabat Daerah dan Tanah Temerloh Pahang / Siti Hasnidaa Senain
Full text linkNowadays, ICT usage is increased among employees in the organization parallel with the trend of technology in the organization. However, does all employees are satisfied with the implementation of ICT at their workplace? Thus, through this research we identified the types of ICT usage in the organization. Also, we identified which factors that gives the most influence of ICT usage toward employees' job satisfaction and also found the relationship between ICT and employees' job satisfaction. The factors that may influence employees' job satisfaction that we used in the research are task, information and skills. The data were collected by questionnaires that distributed at nearby organizations. The employees were given a week to answer the questionnaire before returned it. The finding of the study showed that most employees in an organization are familiar with type of ICT which is letters or documents. Other than that, the most influenced factor of ICT to the employees' job satisfaction is information. Also, there is a relationship between ICT and employees' job satisfaction and it is a weak relationship. As the conclusion, based on the result, the employees are not satisfied with the ICT at their workplace. It is recommended that employees should be train in order to have skill in using ICT. Other than that, employers should provide updated and easy to use ICT equipment
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
