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
Bengkel pemantapan projek pelajar tahun akhir / Norain Isa
No full textSektor pendidikan antara yang terkesan dengan kehadiran pandemik Covid-19 sejak Mac lalu ekoran arahan hanya aktiviti pembelajaran dalam talian sahaja yang dibenarkan sepanjang tempoh Perintah Kawalan Pergerakan (PKP). Bagi pelajar tahun akhir (CEV 652), aktiviti kerja makmal perlu dihentikan sepanjang tempoh PKP. Walaupun kelihatan sukar, namun norma baharu ini perlu diadaptasi oleh semua pihak bagi memutuskan rantaian jangkitan virus ini secara menyeluruh. Penyelidikan pelajar tahun akhir masih boleh dijalankan dengan sedikit pengubahsuaian terhadap kaedah penyelidikan seperti kaedah simulasi, ulasan kajian (Paper Review), penyelidikan secara kajian kes dan kerja makmal (bagi pelajar yang sempat melakukan aktiviti makmal sebelum PKP)

The event was formerly known as Science, Invention, Innovation & Conference. It has garnered multiple successes following the preceding events from 2016 to 2020. SIIC 2020 showcases products commercialization, ideas, inventions and designs that are highly innovative, competing against each other to be recognized as the best among the best. Adhering to the Industrial Revolution 4.0 movement, the competition seeks out outstanding products that are able to keep up with the rise of automation and artificial intelligent innovations – ideas that can change the way we live, work, and communicate for the better. It is also in line with the government's desire to encourage innovation activities in Malaysia
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

Synthesis Of Silver Nanoparticles Using Kyllinga Brevifolia Extract And Immobilisation On Tio2 Nanotubes For Methyl Blue Dye Removal
No full textThe textile industry is an intesive producer of wastewater which unless treated may result in the discharged of toxic and harmful dyes to the environment. One method that can be used to remove dyes is by reduction on a surface of catalyst. The catalyst chosen in this work was silver nanoparticles (AgNPs) synthesised by salt reduction technique. The first part of this thesis focused on the synthesis process of AgNPs. However instead of using typical reductant, AgNPs were synthesised by green chemical route utilising Kyllinga brevifolia extract (KBE) as reducing agent. The KBE was also found to be a good capping as well as stabilizing agent. By controlling the temperature, concentration of AgNO3 as the silver precursor, concentration of KBE and reaction time, the AgNPs were sucsessfully synthesised. The phytochemical constituents in KBE responsible for Ag+ reduction were identified. Carbohydrate, protein, plant sterol (stigmasterol and campesterol) were found to have the highest concentration thus proposed as the main constituents that can reduce Ag+ ions to Ago. KBE derived AgNPs are highly dispersed with ~ 17.64 nm diameter and have quasi-spherical shape. The catalytic removal of MB was then done to demonstrate the properties of AgNPs in removing MB. Four (4) systems were used to investigate the performance of AgNPs; System 1 (AgNPs alone), System 2 (AgNPs + NaBH4), System 3 (AgNPs + KBE) and System 4 (AgNPs on TNTs). From the catalytic study on MB removal, no reduction was observed in System 1. Reduction was the highest in System 2. The pseudo first and
second order approaches were used for the kinetic study of System 2. 100% removal efficiency (%RE) was found to be possible in 30 ppm MB solution with pH 8-10 which followed first order kinetic with reaction rate of 2.5715 min-1. For 100 pm solution, the first order kinetic was 1.4614 min-1. It took less than 5 mins for the 100% removal which is considered to be extremely fast. On the other hand, for System 3, 93 %RE of MB was achieved with a rate of reaction of 0.2663 min−1 at pH 2. The efficient removal is proposed to be due to the process of reduction occuring via electron relay effect whereas in System 3, sedimentation occurred along with the reduction process. However, at the end of the process it was observed that seperation of AgNPs from the treated MB solution was difficult which may pose a secondary pollution. In order to circumvent this, in the second part of this thesis, System 4 was introduced where AgNPs were immobilised on TiO2 before being subjected to be used as catalyst for MB removal. The TiO2 was fabricated on a surface of titanium wire by anodic process. The anodic film was made to be in a form of TiO2 nanotube (TNT) arrays and AgNPs were then dispersed on the TNTs as catalyst support by wet impregnation technique. The TNTs/AgNPs were characterized and their catalytic activity was tested for removal of MB. However, it was found that the removal efficiency was much slower as compared to when AgNPS were used. The reduction of MB by TNTs/AgNPs followed pseudo-first order kinetic with the kinetic rate of 7.5 x 10-3 min-1
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
