No full textBu çalışmanın amacı, Bilim Uygulamaları dersinin öğrencilerin fen okuryazarlığına ve fene yönelik tutumlarına etkisi ile öğrencilerin cinsiyet değişkeni açısından önemli bir istatistiksel farkın olup olmadığını araştırmak ve ders öğretmenlerinin Bilim Uygulamaları dersi hakkındaki görüşlerini değerlendirmektir. Araştırmanın modeli, tarama modelidir. Araştırmanın nicel verilerinin elde edildiği öğrencilerin örneklemi, 2014-2015 eğitim öğretim yılında Ankara'da 6. ve 7. sınıfta öğrenim gören 292 öğrenciden oluşmaktadır. Nitel verilerin elde edildiği çalışma grubu ise Bilim Uygulamaları dersine giren 14 öğretmenden oluşmaktadır. Öğrencilerin fen okuryazarlık düzeyi ve fene yönelik tutumlarının belirlenebilmesi için Duruk (2012) tarafından Türkçe'ye uyarlanan Fen Okuryazarlık Ölçeği ve Akınoğlu (2001) tarafından geliştirilen Fene Yönelik Tutum Ölçeği kullanılarak veriler toplanmıştır. Verilerin analizinde bağımsız örneklemler için t-testi kullanılmıştır. Öğretmenlerin Bilim Uygulamaları dersi hakkındaki görüşlerinin alınması için, öğretmenlerle yarı yapılandırılmış görüşme yapılmıştır. Elde edilen veriler içerik analizi ile değerlendirilmiştir. Araştırma sonucunda, öğrencilerin Bilim
Uygulamaları dersini alıp almama durumları ile fen okuryazarlık ve fene yönelik tutum puanları arasında istatistiksel olarak anlamlı bir farklılık bulunamamıştır. Cinsiyet değişkeni açısından, yalnızca erkek öğrencilerin fene yönelik tutum puanları arasında Bilim Uygulamaları dersini alan öğrenciler lehine anlamlı fark bulunmuştur. Öğretmenler ile yapılan görüşme sonucunda; öğretmenlerin Bilim Uygulamaları dersini öğrenciler için yararlı buldukları ancak uygulama noktasında okulların yeterli fiziksel donanıma sahip olmadığı, öğrenci ve veliler tarafından öneminin kavranamadığı, dersin kaynak kitabının olmaması gibi sebeplerle etkin bir şekilde işlenmediği sonucuna ulaşılmıştır.The aim of this study is to search the effect of the elective science application course to the scientific literacy and scientific attitude of the students and find out if there is a meaningful statistical difference between the students in terms of gender variable and to assess the views of the teachers. The model of the research is the descriptive survey model. The sample of the research releted to quantitative data comprised of 292 studens at the 6 th and 7th grade level in Ankara in 2014-2015 education year. The study group of qualitative data gathered from 14 teachers attending the elective science application course. The data was collected to determine the scientific literacy level and scientific attitude of the students with the Scientific Literacy Scale that is adapted into Turkish by Duruk (2012) and the Scientific Attitude Scale developed by Akınoğlu (2001). Semi-structured interviews were conducted with the teachers for taking their opinions about the science application course. The data collected was analyzed with the content analysis method. At the end of the research, statisticaly meaningful difference was not found between the students attending the science application course and who are not attending the science application course according to the scientific literacy points and scientific attitude points. In terms of the gender variable, there is a meaningful difference only between the points of male students on behalf of the male students attending the science application course. At the end of the interviews done with the teachers, It has been found that the teachers think that the science application course is beneficial but it from the point of application process, there are some problems like that the schools do not have enough physical equipments, student and parents do not conceive the importance of the course, there is no books as source, so that the course is not being applied effectivel
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
Biometric properties of euryhaline fish the sand smelt Atherina boyeri Risso, 1810
No full textIn this study the presence of sand smelt Atherina boyeri Risso, 1810, an invasive and translocated species has been reported in the Hirfanlı Dam Lake, Turkey. The fish samples were collected from the fishermen operating in the area in April 2016. Twenty-three morphometric characteristics of A. boyeri, were taken, including standard length (SL), fork length (FL), total length (TL), preorbital distance, eye diameter, interorbital distance, head length, head width, dorsal fin I nose point distance, dorsal fin II nose point distance, preanal distance, prepectoral distance, preventral distance, dorsal fin I base length, dorsal fin II base length, anal fin base length, pectoral fin base length, ventral fin base length, maximum body height, caudal peduncle height, body width, caudal peduncle width, body weight (W). The SL varied between 62 to 75 mm and weight 2.324 to 4.133 g in females. Whereas in males the SL varied between 56 to78 mm and weight 1.533 to 4.011 g. The sex ratio was slightly in favour of females being 54.4%.Higher Education Commission of Pakista

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
