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

This thesis aims to investigate levels of burn-out and work satisfaction of employees working in the banking sectors in which service is at the forefront and the related concepts are explained in detail. In the investigation of relationship between the job satisfaction and some demographic characteristics, the job satisfaction is positively correlated with age, working years and organizational level. It was found out that there is no significant relationship between the job satisfaction and Gender, marital status, educational level. Looking at some of the relationship between some the demographic characteristics such as income level and working time, the level of the burnout differs. Other demographic characteristics have no significant difference in the levels of employee burn-out. By utilizing The Minnesota Job Satisfaction Questionnaire (MSQ), Banking Professionals job satisfaction scale intrinsic satisfaction, extrinsic satisfaction and general satisfaction levels are measured. Another method, The Maslach Burnout Inventory (MBI), was utilized in order to measure Banking Professionals emotional exhaustion, depersonalization and low personal accomplishment levels were determined. In addition to these, in this research, the Personal Information Form was used. After the data collection, a statistical packet program called 'SPSS' was used to analyze the results. For this analysis, correlation, t test, ANOVA, as a post-hoc test Scheffe's method was utilized. In this analysis, the maximum error threshold was considered to be 0.05. As a result of this research, it was found out that for banking professionals, the job satisfaction was inversely correlated with the level of burnout. That is when the Job satisfaction increases, the level of burnout decreases.Günümüzde çalışma hayatında iş doyumunun ve tükenmişliğin büyük önemi vardır. Hizmetin ön planda olduğu sektörlerden biri olan bankacılık sektöründe çalışanların tükenmişlik ve iş doyum düzeylerini inceleyen bu tez çalışmasında konu detaylı olarak açıklanmaya çalışılmıştır. İş doyumu ile bazı demografik değişkenler arasında yapılan incelemede yaş, çalışma süresi ve statüsü arttıkça iş doyumunun arttığı da tespit edilmiştir. Cinsiyet, medeni durum, eğitim düzeyi gibi değişkenlere göre iş doyumunun önemli bir farklılık göstermediği tespit edilmiştir. Tükenmişlik ile bazı demografik değişkenlere bakıldığında gelir düzeyi ve hizmet süresine göre tükenmişlik düzeyinin farklılaştığı tespit edilmiştir. Diğer demografik değişkenlere göre çalışanların tükenmişlik düzeylerinde anlamlı bir farklılık bulunmamaktadır. Bankacıların iş doyum düzeylerini ölçmek için Minnesota İş Doyum Ölçeği kullanılarak cevaplayıcıların içsel doyum, dışsal doyum ve genel doyum düzeyleri belirlenmiştir. Araştırmada kullanılan bir diğer ölçek olan Maslach Tükenmişlik Ölçeği ile banka çalışanlarının duygusal tükenme, duyarsızlaşma ve düşük kişisel başarı düzeyleri belirlenmiştir. Ayrıca araştırmada ""Kişisel Bilgi Formu"" kullanılmıştır. Araştırmadan elde edilen verilerin istatiksel analizleri için ""SPSS"" paket programı kullanılmıştır. Verilerin çözümlenmesinde korelasyon, t testi, Anova, Post-hoc testi olarak da Scheffe testi kullanılan araştırmada, hata payı üst sınırı 0,05 olarak kabul edilmiştir Araştırma sonucunda banka çalışanlarının iş doyum düzeyleri ile tükenmişlik düzeyleri arasında negatif ilişki tespit edilmiştir. İş doyumu arttıkça tükenmişlik azalmaktadır
Virtual water trade: An empirical application, for Turkey, on agricultural products
No full textSu, küresel boyutta kıt olmaya doğru giden en önemli doğal kaynaklardan biridir. Yapılan çalışmalar gelecekte Türkiye'de yoğun bir su sorunu yaşacağına dikkat çekmektedir. Bu nedenle küresel boyutta olduğu gibi Türkiye özelinde de su tasarrufunun ve güvenliğinin sağlanması çok önemli olmaktadır. Bu durumda, sanal su alternatif bir kaynak olarak görülmekte ve bu ticaret türü önemli hale gelmektedir. Konunun bu öneminden hareketle, Türkiye'de en yüksek su kullanımının tarım sektöründe olması sebebiyle tarımsal ürünlerle gerçekleştirilen sanal su ticaretinin incelenmesine ihtiyaç duyulmuştur. Bu bağlamda bu tez çalışmasının amacı, su sorununa dikkat çekerek Türkiye'de tarımsal ürünler ile gerçekleşen sanal su ticaretini analiz etmektir. Çalışmada tarımsal üretim endeksi, Türkiye GSYH/Dünya GSYH, reel döviz kuru, sulanan alan, sıcaklık, yağış değişkenlerinin sanal su ticaret dengesine (toplam ihracat miktarı/toplam ithalat miktarı) etkisi ekonometrik ve istatistiksel olarak ortaya konulmuştur. Bu kapsamda söz konusu değişkenler ile sanal su ticaret dengesi arasındaki ilişki ARDL sınır testi yöntemi kullanılarak incelenmiştir. Çalışmada oluşturulan modelde yer alan değişkenlerden sadece GSYH değişkeninin bağımlı değişken üzerindeki etkisinin istatistiksel olarak anlamlı olmadığı tespit edilmiş ve modelden çıkarılmıştır. Diğer değişkenlerden sıcaklık, sulanan alan değişkenlerinde pozitif yönlü bir birim değişmenin, sanal su ticaret dengesine pozitif etki edeceği görülmüştür. Bununla birlikte yağış, tarımsal üretim endeksi ve reel döviz kuru değişkenleri ile sanal su ticaret dengesi arasında negatif yönlü bir ilişki tespit edilmiştir.Water is one of the most important natural resources, likely to be scarce in a global extent. Studies made indicate that Turkey encounter an intense water problem in the future. For this reason, it is very important to save water and ensure water safety in Turkey as well as in a global extent. In this case, virtual water is considered as an alternative water source and virtual water trade is becoming important. Based on this importance of the issue, in addition, due to the fact that the highest water use in Turkey is in the agricultural sector, it is essential that the virtual water trade carried out in agricultural products be examined. In this context, the aim of this thesis study is to draw attention to the water problem and to analyze the virtual water trade, carried out with agricultural products, in Turkey. In the study, the effects of Agricultural Production Index, Turkey GDP/World GDP, Real Exchange Rate, Irrigated Area, Temperature, Precipitation variables on virtual water trade balance (virtual water export amount/virtual water import amount) were revealed econometrically and statistically. In this context, the relationship between aforementioned variables and the virtual water trade balance was examined by applying the method of ARDL limit test. It was determined that only the effect of the GDP variable, among the variables in the model created in the study, on the dependent variable was not statistically significant and was excluded in the model. It was observed that a positively directed unit change in the variables of temperature and irrigated area, among the other variables, would have a positive effect on the virtual water trade balance. Furthermore, an avoidant relationship was found between the variables of precipitation, agricultural production index and real exchange rate and virtual water trade balance
