    Purpose of this study is to compare the latest world championships with the old system and the latest world championship competitions with the new system, and to compare the competitions in two different systems by conducting activity and technical analysis. Thus, the technical analysis of the 2007 and 2017 world taekwondo championship women's and men's finals was performed. SPSS 22.0 package program was used for statistical analysis of the acquired data and results were evaluated at p <0.05 significance level. Mann - Whitney U Test was applied to the techniques used (punch, palding, pusachagi, yopchagi, dwichagi, neryochagi, dollyochagi, pandedollyo), total technical numbers, frequency and percentage analysis of points and penalties and pairwise comparisons. When the findings of the study were examined, there were statistically meaningful differences found between the number of techniques used in the competition and the techniques used in the competitions in 2017 (women; p = .001, men; p = .001). In the world championship finals in 2007, while women athletes used a total of 404 techniques, they used 1152 techniques in the world championship finals in 2017. In 2007, totally 525 techniques were used in men and in 2017, 1205 techniques were used. As a conclusion, in Taekwondo, when the competitions between the old system and the new system are compared, it can be said that in the new system, the athletes use much more techniques and their scores increase considerably depending on the changing rules and the technical numbers.

    Bu araştırmanın amacı 2019 Yıldızlar Türkiye Taekwondo Şampiyonasında kazanan ve kaybeden bazı kadın ve erkek sporcuların maç analizlerinin yapılmasıdır. Araştırmada erkeklerde 4, kadınlarda 3 sıklet olmak üzere toplam 7 sıkletin maçları video kameraya kaydedilmiştir. İlk turlar, yarı final ve finaller olmak üzere toplam 84 maç kaydedilmiş ve sonrasında Mavi Var ve arkadaşları (2015) tarafından geliştirilen ‘Taekwondo Maç Analiz’ formu kullanılarak analiz edilmiştir. Elde edilen verilerin analizinde tanımlayıcı istatistikler kullanılarak ortalama değerler, frekans ve yüzdelik değerler alınmıştır. İkili karşılaştırmalarda Independent Samples Test kullanılmıştır. Bulgular incelendiğinde erkek sporcuların maç içerisinde aldıkları cezaların kadın sporculara göre anlamlılık gösterdiği görülmüştür (p<0.05). Kazanan erkek sporcuların maç içerisindeki uyguladıkları tekniklerin ortalama değerlerine bakıldığında özellikle yarı final ve finallerde kaybeden sporculara göre daha az teknik uyguladıkları buna rağmen daha fazla puan kazandıkları görülmektedir. Kadın sporcularda ise kazanan sporcuların yarı final ve finallerde daha fazla teknik uygulayarak rakiplerinden daha fazla puan aldıkları görülmektedir. Sonuç olarak yıldızlar taekwondo müsabakalarında erkekler daha az ama isabetli teknik uygulayarak maç kazanmakta, kadınlar ise daha çok teknik uygulayarak puan alma şansını artırmakta olduğu söylenebilir.Trdizi

    The effects of yoga asanas on proprioception, balance, and flexibility in middle-aged sedentary women: Orta yaş sedanter kadınlarda yoga asanalarının propriyosepsiyon, denge ve esneklik üzerine etkileri

    The aim of this study was to examine the effects of yoga asanas on proprioception, balance, and flexibility in middle-aged sedentary women. A quantitative pretest–posttest control group design was employed. Thirty sedentary women aged 45 and above voluntarily participated in the study and were randomly assigned to an experimental group (n=17) and a control group (n=13). The experimental group participated in a yoga asana program for eight weeks, three weekly sessions lasting 60 minutes each. The joint position sense, sit-and-reach, and Flamingo balance tests were used to measure proprioception, flexibility, and balance, respectively. Data were analyzed using a mixed ANOVA, with a significance level set at p&lt;.05. Results indicated that yoga significantly improved flexibility and balance parameters but did not produce a statistically significant change in proprioception. Moderate to high effect sizes were observed in flexibility scores, while notable improvements were found in balance performance. However, proprioceptive outcomes showed no significant differences. In conclusion, yoga can be an effective method to enhance flexibility and balance in middle-aged sedentary women. The findings suggest that incorporating yoga-based exercise programs into public health initiatives may enhance physical fitness among sedentary individuals. (Extended English summary is at the end of this document) Özet Bu araştırmanın amacı, orta yaş sedanter kadınlarda yoga asanalarının propriyosepsiyon, denge ve esneklik üzerindeki etkilerini incelemektir. Araştırmada nicel yöntemlerden kontrol gruplu ön test–son test deneysel deseni kullanılmıştır. Araştırmaya, 45 yaş üzeri sedanter yaşam süren 30 kadın katılmış; katılımcılar rastgele atama yöntemiyle deney (n=17) ve kontrol (n=13) gruplarına ayrılmıştır. Deney grubuna sekiz hafta boyunca haftada üç gün, 60 dakikalık yoga asanaları programı uygulanmıştır. Araştırmada propriyosepsiyon için eklem pozisyon hissi testi, esneklik için otur–uzan testi ve denge için Flamingo testi kullanılmıştır. Verilerin analizinde parametrik testlerden karma ANOVA yöntemi uygulanmış, anlamlılık düzeyi p&lt;.05 olarak belirlenmiştir. Bulgular, yoga uygulamalarının esneklik ve denge üzerinde anlamlı gelişim sağladığını, ancak propriyosepsiyon üzerinde istatistiksel olarak anlamlı bir değişim oluşturmadığını göstermiştir. Deney grubunda esneklik parametrelerinde orta–yüksek düzeyde etki büyüklükleri gözlenirken, denge becerilerinde belirgin gelişmeler elde edilmiştir. Buna karşılık propriyosepsiyon düzeylerinde anlamlı fark saptanmamıştır. Sonuç olarak yoga, orta yaş sedanter kadınlarda esneklik ve dengeyi geliştirmede etkili bir yöntem olarak değerlendirilebilir. Bulgular, yoga uygulamalarının sedanter kadınlarda fiziksel uygunluğu desteklemek amacıyla toplum sağlığı programlarına entegre edilebileceğini göstermektedir

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Full text link
    We 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
