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
Hipermobilitas Sendi pada Anak-anak dengan Idiopatik Skoliosis
Full text linkAbstrak Hipermobilitas sendi adalah suatu keadaan dimana gerakan sendi kecil dan sendi besar meningkat, sehubungan dengan gerakan normal serta lebih sering terjadi pada anak-anak, dan lebih banyak pada anak perempuan. Hipermobilitas sendi didiagnosis hampir setengahnya pada anak-anak dengan skoliosis idiopatik, dengan derajat ringan dan sedang, serta biasanya terjadi lebih tinggi pada skoliosis dengan skoliosis lengkung tunggal. Skoliosis idiopatik adalah suatu keadaan skoliosis dimana secara klinis dan radiologis tidak ditemukan adanya penyebab khusus.Kata kunci : hipermobilitas sendi, idiopatik skoliosis Abstract Joint hypermobility is a state where the movement of the small joints and large joints increased with respect to normal movement and is more common in children, and more in girls. Joint hypermobility was diagnosed almost by half in children with idiopathic scoliosis, with mild and moderate, and usually occurs higher in the single-curve scoliosis. Idiopathic scoliosis is a condition in which the scoliosis is clinically and radiologically did not reveal any specific cause. Key words: joint hypermobility, idiopathic scoliosisÂ
Variasi Anatomi Pola Percabangan Arcus Aorta
Full text linkAortic arch is part of the pars thoracic aorta, located in the superior mediastinum. Its function is to carry oxygenated blood to all parts of the body in systemic circulation. From five different studies, all of them showed variations of the aortic arch branching patterns. This article discusses the variation of aortic arch branching patterns using the Natsis classification. The study found that the variations in the branching pattern are mainly of type I and type II.Arcus aorta merupakan bagian dari pars thoracica aorta yang terletak di mediastinum superior, berfungsi untuk membawa darah beroksigen ke seluruh bagian tubuh dalam peredaran sistemik. Dari lima studi yang berlainan, semua menunjukkan variasi pola percabangan arcus aorta. Artikel ini membahas variasi pola percabangan arcus aorta menggunakan klasifikasi Natsis. Variasi yang paling banyak ditemukan pada studi ini adalah tipe I dan tipe II
Kaitan Pemakaian Sepatu Hak Tinggi dengan Lordosis Lumbal
Full text linkAbstrak Sejak masa Louis XIV di perancis, para wanita mulai memakai sepatu hak tinggi. Tetapi semua itu ternyata membawa efek negatif. Beberapa wanita sering mengeluh dengan memakai sepatu hak tinggi menyebabkan mereka nyeri punggung, hal ini membuat banyak dokter dan ahli terapi mulai berpikir bahwa sumber nyeri tersebut adalah sepatu hak tinggi yang menyebabkan peningkatan kelengkungan lordosis lumbal tulang belakang. Pemakaian sepatu hak tinggi akan mengakibatkan peningkatan lordosis lumbal yang diakibatkan oleh karena berkurangnya sudut fleksi dari lumbal dan menyebabkan meningkatnya otot erector spinae untuk menopang tubuh yang tidak stabil, supaya tetap berdiri tegak. Hal ini terjadi pada jangka panjang akan menimbulkan kelelahan dan ketidaknyamanan pada si pemakai, yang pada akhirnya akan berujung pada terjadinya low back pain.Kata kunci : Sepatu hak tinggi, lordosis lumbal, low back pain  Abstract At the time of Louis XIV in France, the women began to wear high heels. But it turned out to have negative effects, some women often complain with wearing high heels cause them pain, it makes doctors and therapists began to think that the source of the pain is high-heeled shoes that cause the increase of the lordosis curvature of the lumbar spine . The use of high-heeled shoes will lead to increased lumbar lordosis resulting from the reduced angle of lumbar flexion and causing increased erector spinae muscles to support the body unstable, for standing normally. This situation in long term will lead to fatigue and discomfort, which will eventually lead to the occurrence of low back pain. Keywords: high heels, lumbar lordosis, low back pai
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
Variasi Anatomi Circulus Arteriosus Willis
Full text linkAbstrakCirculus arteriosus Willis (CW) merupakan suatu lingkaran anastomosis berbentuk cincin yang terletak di fossa ossa interpeduncularis basis cranii, berfungsi untuk mendistribusikan darah yang masuk melalui arteri carotis interna dan arteri vertebralis ke setiap bagian dari kedua hemispherium cerebri. Dari empat studi yang berlainan semua menunjukkan adanya variasi atau anomali dari CW. Variasi yang banyak ditemukan pada studi yang ada pada artikel ini adalah suatu keadaan hipoplasia pada pembuluh darah. Berbagai tipe variasi dari komponen CW yang banyak ditemukan adalah arteri communicans anterior. Kata kunci : Circulus arteriosus Willis, variasiAbstractCirculus arteriosus Willis (CW) is a circular ring-shaped anastomosis located in the fossa ossa interpeduncularis skull base, serves to distribute the incoming blood through the arteri carotis interna and vertebral artery into every part of the both hemispherium cerebri. From four different studies, all of them showed variations or anomalies of CW. All of variation which found in many existing studies on this article are hipoplasia of the blood vessels. Various types of variations of CW components commonly found is communicans anterior artery. Key words: Circle arterosus Willis, variatio
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
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
