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

No full textPersil Özkan, Özlem (Arel Author)Besinler, üretim zincirindeki çeşitli aşamalarda kontamine olabilirler. Toplu beslenme üretimi ve servisi yapan iş yerlerinde personel hijyeninin sağlanması birçok besin kaynaklı hastalığın önlenmesinde etkili olabilmektedir. Eller ve besinle teması olabilen vücut bölgelerinin temizliği bu bakımdan oldukça önemlidir. Besinlerin eller yoluyla kontaminasyon riski çok yüksektir. Toplu beslenme yapılan kurumlarda besinlerin hazırlanması ve servisinde çalışan personelin kişisel ve mutfak hijyeni konusunda eğitimli ve bilgili olması insan sağlığının korunması ve sürdürülmesi açısından vazgeçilmezdir
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
Otozomal dominant polikistik böbrek hastalarının besin tüketimleri ile böbrek kist volümleri arasındaki ilişkinin incelenmesi
Get PDFOtozomal dominant polikistik böbrek hastalığı (ODPKBH) insanlarda en sık görülen kalıtsal hastalıklardan biridir. Bilateral böbrek kistleri ile karakterize sistemik bir hastalıktır ve son dönem böbrek yetmezliği (SDBY) vakalarının yaklaşık %10’undan sorumludur. ODPKBH’da morbidite ve mortalitenin en önemli nedeni kardiyovasküler olaylardır ve en yaygın semptomu erken dönemde başlayan hipertansiyondur. Bu çalışma besin ögeleri alımı ile böbrek volümleri arasındaki ilişkiyi incelemek amacıyla yapılmıştır. Nisan 2014 ve Temmuz 2014 tarihleri arasında İstanbul Fatih Kamu Hastaneler Birliği Genel Sekreterliği Haseki Eğitim ve Araştırma Hastanesi nefroloji polikliniğine başvuran; aile hikayesi, klinik bulgular ve manyetik rezonans görüntüleme yöntemleri ile belirlenmiş böbrek volümü ile kesin tanısı konmuş, yaş ortalaması 48.6±11.3 yıl olan 22 erkek ve 38 kadın ODPKBH hastası üzerinde yürütülmüştür. Hastaların kişisel özellikleri, biyokimyasal ve idrar parametreleri, böbrek volümleri ve antropometrik ölçümleri değerlendirilmiştir. Hastaların enerji ve besin ögeleri alımları 3 günlük besin tüketim kayıdı ile belirlenmiştir. Hastaların ortalama eGFR 54.8±36.46ml/dk/1.73m2 olarak hesaplanmıştır ve ortalama böbrek volümü 1012±776.8ml bulunmuştur. Hastaların vücut ağırlıkları başına günlük aldıkları enerji 25.57±9.32kkal/kg ve protein 0.87±0.32g/kg olarak saptanmıştır. Hastaların diyet enerjisinin karbonhidrattan gelen yüzdesi ortalama %49±7, proteinden gelen %14±2 ve yağdan gelen %36±6 olarak bulunmuştur. Hastaların doymuş yağ alım yüzdesi %11.6±3.6 olarak bulunmuştur. Hastaların, özellikle kadın hastaların diyetle folatı günlük önerilen değerin (DRI) altında tükettikleri saptanmıştır. Hastaların ortalama kalsiyum (DRI erkelerde %70.3, kadınlarda %69.6) ve potasyum (DRI erkeklerde %65.1, kadınlarda %61.4) alımları DRI önerilerinin altında olduğu belirlenmiştir. Hastaların diyet sodyum alımları DRI değerlerinin üstünde bulunmuştur (erkeklerde %186.1, kadınlarda %176). Hastalar ortanca böbrek volümü değerine göre (743 ml) karşılaştırıldığında diyetle karbonhidrat, protein ve yağ alımlarında bir fark bulunmamıştır (karbonhidrat %49.3±7.7-%49.2±6.9, protein %14.5±2.8-%13.9±2.5 ve
yağ %36.3±6.7-%36.8±6.5) (p>0.05). Hastaların böbrek volümleri arttıkça kalsiyum, magnezyum, potasyum, sodyum ve çinko alımın azaldığı, fosfor ve demirin alımın ise benzer olduğu saptanmış fakat istatistiksel olarak anlamlı bulunmamıştır (p>0.05). Sonuç olarak, hastaların yağ, doymuş yağ ve sodyum alımları yüksek; folat, kalsiyum ve potasyum alımları ise yetersiz bulunmuştur. Tüm bu besin ögeleri, ODPKBH’da mortalite ve morbiditenin en önemli sebepleri olan kardiyovasküler hastalıklar ve hipertansiyonla ilişkilidirler. ODPKBH’da tıbbi beslenme tedavisi önerilerinin kısıtlılığı sebebi ile SDBY gelişimine doğru daha fazla böbrek hasarını önlemek ve hastalığın ilerleyişini yavaşlatmak için hastaların renal bir diyetisyen takibinde olması gerekmektedir.
Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common inherited diseases. ADPKD is a multi-systemic disease characterized by bilateral renal cysts and is responsible for about 10% of cases of end-stage renal disease (ESRD). Cardiovascular problems are a major cause of morbidity and mortality in patients with ADPKD and a common early symptom is hypertension. This study was conducted to determine the relationship between daily dietary nutrient intakes and kidney volume. The study was carried out on 22 male and 38 female patients, with a mean age of 48.6±11.3 years, who were diagnosed with ADPKD using evidence of family history, clinical symptoms and total kidney volume which was determinated by magnetic-resonanse imaging at Istanbul Fatih Public Hospital Union General Secretary Haseki Training and Research Hospital Nephrology clinic between May 2014 and July 2014. Patients’ data including personal characteristics, biochemical and urinary parameters, kidney volumes and anthropometric measurements were determined. In this study the nutrient intakes of patients were estimated by the 24-h dietary records obtained on 3 consecutive days. The mean eGFR was calculated to be 54.8±36.46 ml/dk/1.73m2 and the mean kidney volume was 1012±776.8ml. Patients total dietary energy intake was found to be 25.57±9.32kcal/kg/day and their total dietary protein intake was found to be 0.87±0.32g/kg/day. Patients’ percentage of energy from carbohydrates was determined as 49±7%, from protein was 14±2% and from total fat was 36±6%. Patients’ mean dietary saturated fat intake was found to be 11.6±3.6%. Patients’, especially women, mean dietary folat intake was much lower than the DRI (Daily Recommended Intake). Patients’ mean dietary calcium (DRI men 70.3%, women 69.6%) and potassium intakes (DRI men 65.1%, women 61.4%) were insufficient. Patients’ mean dietary sodium intake was higher than the DRI recommendation (men 186.1%, women 176%). It was found that when patients were divided in to two groups, by their median kidney volume (743 ml), there was no difference in their carbohydrates, protein and total fat intakes (carbohydrates 49.3±7.7%-49.2±6.9%, protein 14.5±2.8%-
13.9±2.5% and total fat 36.3±6.7%-36.8±6.5%) (p>0.05). Dietary calcium, magnesium, potassium, sodium and zinc intakes were lower; phosphorus and iron intakes were similar in patients with higher kidney volume than the patients with smaller kidney volume but these relationships weren’t statistically important (p>0.05). As a conclusion, patients’ total fat, saturated fat and sodium intakes were higher; dietary folat, calcium and potassium intakes were inadequate. All of these nutrients related with cardiovasculer diseases and hypertension which are the most common mortality and morbidity causes of ADPKD. Due to the lack of medical diet therapy recommendations on patients with ADPKD, patients should be followed by a specialist (renal) dietitian to protect malnutrition or hypertension and to prevent furter renal injury in order to slow polycystic kidney progression to ESRD
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
