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
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

BÜTÜNCÜL BİR MODEL OLARAK AHİLİGİN GİRİSİMCİLİK BOYUTUNUN ZİHNİYET TEMELLERİ
No full textnsanlık, tarih boyunca hep mükemmel toplumun pesinde kosmustur. Türk-
slam Medeniyeti dengeli fert ve dengeli toplumu saglayarak mükemmele
yakın bir toplumun en güzel örnegi olan Ahiligi bundan yüzyıllar önce
olusturmustur. Türk insanının öz degerleri olan akıl, ahlak ve çalısmayı
tasavvuf egitimi ile harmanlamıs bir ekonomik ve sosyal model olan Ahilik
Kurumu insanlıgın refah arayısını temin için sosyal hayatı her yönüyle
kucaklamıstır. Ahi Evran'ın insanlık âlemine miras olarak bıraktıgı ve
Anadolu'da yasayan bütün insanların gurur kaynagı olan Ahiligin daha iyi
anlasılmalı ve yeniden kurum ve kurallarıyla canlandırılıp insanlıga armagan
edilmelidir. Burada karsımıza zihniyet kavramı çıkmaktadır. Toplumsal
yapıdaki bütün kesimlerin sahip oldugu deger yargıları, tercihler ve egilimlerin
hepsini açıklayan zihniyet aslında toplumların hayat tarzını belirleyen
düsünce yapısıdır ve bu hayat tarzı ile zihniyet arasındaki iliski de toplumun
bilgi hiyerarsisini ve kültür unsurlarını belirler. Ahinin zihniyet yapısının tam
olarak anlasılabilmesi, zihniyetin olusmasını saglayan unsurların neler
oldugu, içinde yasadıgı toplumun bilgi hiyerarsisi ve kültürünün iyi idrak
edilmesi ile saglanabilir. Fakat bu kurumu ve yetistirdigi fert olarak Ahiyi tam
anlayabilmemiz için Batı Avrupa pozitivist düsüncesinden sıyrılarak
incelemelerde bulunmamız gerekir
RESEARCH IN USAGE OF FLY ASHES IN THE PRODUCTION OF INTERLOCKING CONCRETE PAVE
No full textUçucu kül (UK), termik santrallerde kömürün yakılması sonucu olusan atık malzemedir. Bu yan ürün betonda puzolanik malzeme olarak kullanılmaktadır.
Çimento veya beton üretiminde UK belirli oranlarda kullanılmaya baslamıstır. UK'ler beton üretiminde puzolanik katkı veya dolgu (filler) malzemesi olarak
kullanılmaktadır. UK kullanım alanının arttırılması hem ekonomi hem de çevre kirliligi açısından önemlidir.
Beton kilitli parke tasları, son zamanlarda oldukça yaygın kullanılmaktadır.
Özellikle sehir içi yol ve kaldırımlarda, araç park alanlarında, ticari merkezlerde, fabrika çevreleri ve benzeri yerlerde yogun çalısmalara maruz kalan bölgelerde kullanılmaktadır. Parke tası üretimi, UK kullanımı için genis hacimli bir alandır. UK'ün parke tası üretiminde kullanılması, daha iyi parke tası üretimi, ekonomiklik ve çevre açısından iyi bir yaklasım olacaktır.
Çalısmada üç farklı santralden elde edilen uçucu kül %10-20-30-40 oranda çimento yerine ikame edilerek kullanılmıstır. Üretilen parke taslarının yarısı
kontrol numunesi olarak kullanılmıstır. Diger yarısı tuzlu küre maruz bırakılmıstır. Kilit taslarının yarmada çekme, su emme ve asınma özellikleri
saptanmıstır.Genel olarak %10-20 UK ikameli numuneler, sahit numuneye benzer sonuçlar vermistir. Tuzlu sulama kürü, erken yaslarda, yarmada çekme dayanımını
arttırırken, ileriki yaslarda düsürmüstür. Diger fiziksel özelliklerde, tuzlu su kürü etkisi altında, UK kullanılan numuneler daha iyi sonuçlar vermistir.Fly ash is a waste material which is produced in the thermal power plants
by burning coal. This side product can be used as pozzolanic material in the
concrete.Fly ash has started to be used in concrete production in certain
amounts.Fly ashes are used as pozzolanic ingredients or filler materials.
Increasing the usage areas of the fly ash is important for both economical
and environmental reasons.
The usage of the interlocking concrete pave has been increased recently. It is
used in the areas in local roads and pavements, parking sites, commercial
centers and industrial areas, which are exposed to intensive usage.
Production of the concrete pave is a wide area for the consumption of the
FA. The usage of the FA in the production concrete pave is a more high
quality production, more economical and a more environmentally friendly
approach.
In this study, fly ash gathered from three different thermal power stations
has been used as a substitude to cement in 10-20-30-40 % ratios.Half of the
produced paves has been used as control example.The other half has been
exposed to salt cure.The splitting tensile strenght and water absorbtion
characteristics of the pave have been determined.
Generally, the examples with 10-20% substitude, had outcomes similar to the
witness example.While the salt cure has improved the tensile strenght in early
ages, it has reduced it in older ages.In other physical properties, under exposure
to salt cure, the examples with the fly ash had better outcomes
