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
Kesan Penggunaan Internet Dalam Penulisan Karangan Pelajar Sekolah
Full text linkKajian ini bertujuan untuk mengenal pasti kesan penggunaan internet dalam penulisan
karangan Bahasa Melayu di kalangan pelajar sekolah. Sampel kajian terdiri daripada 114
pelajar tingkatan empat di daerah Hulu Langat. Sebanyak 57 orang pelajar ditempatkan
dalam kumpulan eksperimen dan 57 orang pelajar ditempatkan dalam kumpulan
kawalan. Pencapaian dilihat melalui tiga jenis karangan berbentuk fakta iaitu karangan
jenis pendapat, perbincangan dan rencana. Skor didasarkan dengan menggunakan skema
Pemarkahan Karangan Bahasa Malaysia Kertas 1 (110311) daripada Lembaga
Peperiksaan Malaysia. Untuk melihat tanggapan pelajar dalam penulisan karangan
daripada aspek motivasi, sikap, minat dan efikasi kendiri, instrumen soal selidik
digunakan. Instrumen soal selidik ini telah diubahsuai mengikut kesesuaian kajian
seperti aspek motivasi menggunakan instrumen yang diubahsuai daripada instrumen
Warschauer (1 996), sikap daripada instrumen Loyd dan Loyd (1 985), minat daripada
instrumen Cramer dan Smith (2000) dan instrumen Shrneck dan Geister - Breintein,
(1995) untuk efikasi kendiri. Kajian ini adalah jenis eksperimen kuasi yang
menggunakan reka bentuk, praujian dan pascaujian untuk kumpulan tak seiupa (the pre
test post test, non equivalent group designs). Pencapaian pelajar bagi kumpulan
eksperimen adalah signifikan (p < 0.05), dibandingkan dengan kumpulan kawalan.
Penggunaan internet dalam penulisan karangan juga telah memberikan niotivasi, sikap,
minat dan efikasi kendiri yang positif dalam penulisan karangan bahasa Melay
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
Continuing professional development of expert teacher educators
Full text linkThe purpose of this study was to uncover the teacher educator professional journey
since the day they become teacher until they were recognized as expert in teacher
education. Research on expertise professional development was extensive, but little
attention was explored on how expertise grew over time. Knowledge and expertise
acquired by the experts were tacit in nature and difficult to share. To access this,
experts need to make their expertise explicit. Therefore, this study explored the teacher
educators’ journey along their continuing professional development (CPD) as there
was not much study done on expert teacher educator. Underpinning theories of this
study covers stages of professional development, reflection in action, tacit knowledge,
cognitive analysis and educational psychology. Narrative method was applied in this
study, using in-depth, semi-structured interview to highlight how participants
negotiate their identities throughout their profession. Seven participants were selected
through purposive sampling. Transcribed, observation and document analysis data
were used to situate individual experience within participants’ personal experiences to
check the similarities and differences in pattern. The framework consists of gathering
stories, analyzing them for key elements of the story, and then rewriting the stories to
place them within a chronological sequence. The results revealed that there were
various pathways the professionals can take in order to become expert. These
pathways originated from critical events that occur within their career, eventually lead
to the increase in roles and responsibilities of the teacher educators, and the
progression of their career. These occurred naturally across the path of the
participants’ career, and brought about changes in the person, which motivated them
to acquire new knowledge, and changed their attitudes holistically. Participants took
pride of their craftsmanship and their realization of self. They become individuals who
were involved in deliberate practice, portrayed individual value of their own, acquired
leadership through experience, and were in positive environment to develop. The
study implicates that a novice needs to undergo long periods of training and practice
before they can become experts. It is impossible to shorten the trip, considering the extensive experience which is fundamental to development. Experts can become the
role model for professionals in CPD, as they have experienced deliberate practice and
have achieved success. Thus, the discovery of this professional development path is
important as it provides a model for the juniors to follow. This means that for those
who have the intention or ambition to become experts can use them as role models,
and follow the professional pathways that the research participants have gone through
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
Effect of fish meal supplementation in diet on growth performance and carcass characteristic of turkey
Full text linkTurkey meat is gaining in importance in Malaysia with indications of increase in consumption of turkey with positive feedbacks in media such as newspaper, where sales of turkey were reported to be very good. There are more farms operating now compared to 5 years back. The type of turkey breeds used seems to be random-bred type of turkeys which can be call as ‘village type” of turkey since they do not grow very big as commercial meat type turkey breed. Due to the unavailability of commercial feeds, most farmers are using commercial broiler chicken feed as substitute. Turkey needs diet of high protein compared to chicken. Poults need 28 % crude protein in the starter diet compared to 21 percent required by broiler chicken. The value-added diet is created by adding fish meal to provide a diet with the required protein levels. Two diets were used in the study. A commercial broiler diet and a value added diet. This research aim is to study effect of fishmeal in the diet on growth performance and carcass characteristic of turkey. The objectives of this study were to compare the effect of protein level in diets on the growth performance and carcass of turkey. Two diets were used; value added diet (diet1) and broiler starter (diet2). A total 80 poults were assigned to 8 cages randomly with four replicate each. The poults were gave the treatment from day old poult. The age of turkey sample was from 70 days old. The average weight of turkey was 1.4kg. The FCR and turkey weekly weight show that there is no significant different between diet 1 and diet 2. The live weight for both treatment diets was not significant different even the diet 1 has slight higher live weight compare to diet 2. There was no significant different in dressing percentage and carcass weight from both diet. The carcass composition of the turkey was not significant different for gizzard, liver, wing, neck, drumstick, wing drumstick, back, breast and thigh for both diets. There was significant different (P0.05). In conclusion, the growth performance and carcass composition of turkey is not affected with value added feed, but did not give negative effect because its increase the weight of turkey. The broiler feed does not need to change to value added feed because there is no effect in growth performance
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
