Presence of Dianthus roseoluteus Velen. (Caryophyllaceae) in Turkey and a New Species: Dianthus macroflorus Hamzaoglu
No full textThe presence of Dianthus roseoluteus Velen. species in Turkey is based on specimens collected from Antalya province. After the publication of Flora of Turkey, many specimens have been collected from Thrace (Kirklareli and Edirne provinces) that belong to this species. A comparison of the specimens collected from Antalya and Thrace revealed that they were morphologically different. The literature survey verified that the specimens collected from Thrace were Dianthus roseoluteus. The species collected from Antalya province is a new species, Dianthus macroflorus Hamzaoglu, and its description, pictures, distribution, habitat, and threatened categories are given. Its general morphology and seed micromorphology are compared with the related species, Dianthus roseoluteus. In addition to phylogenetic relationships between some closely related Dianthus species that belong to section Dentati in Turkey, Dianthus macroflorus and 13 additional Dianthus species sequences obtained from GenBank were examined with DNA sequence data from the nuclear ribosomal ITS region. These analyses were supported with morphological data

Examining the Studies on “Digital Gaming”: A Bibliometric Analysis
No full textTRT AkademiDepending on the technological developments experienced, the importance of the concept of digitalization, which we encounter in all areas of our lives, is increasing. As a reflection of this situation, the definition of the concept of game has changed to include digital technologies. When the literature is examined, it has been determined that there is an increase in digital game-based studies. The main purpose of this research is to examine the studies on digital game in the literature by bibliometric method. Within the scope of the study, researches related to digital games were examined in terms of content and bibliometrically. As a result of the examination, the general trends in the relevant field, the authors who studied and the classification of the studies according to the years were shown with visual maps. Web of Science (WoS) was used to obtain the data. A total of 920 publications were reached in the research carried out by scanning the term Digital game. Content analysis and bibliometric analysis were used in the analysis of the data. In the research, it was concluded that the distribution of the studies in WoS by years was between 2004-2022, and the most productive author was Gwo-Jen Hwang. It has been determined that the university with the most publications on the related subject is National Taiwan University of Science and Technology, and the country with the most publications is America. According to the common word analysis, it was concluded that the most frequently repeated keyword in the studies was Digital game-based learning, and according to the common citation analysis, the most cited author was Prensky. As a result of the co-author analysis, it was seen that the authors worked in small groups and there were no multiple connections between the authors.Yaşanan teknolojik gelişmelere bağlı olarak hayatımızın her alanında karşılaştığımız dijitalleşme kavramının önemi artmaktadır. Bu durumun bir yansıması olarak da oyun kavramının tanımı dijital teknolojileri kapsayacak şekilde değişmiştir. Alan yazın incelendiğinde dijital oyun temelli çalışmalara yönelik bir artış olduğu belirlenmiştir. Bu bağlamda araştırmanın temel amacı “dijital oyun” ile ilgili yapılmış çalışmaların bibliyometrik yöntemle incelenmesidir. Çalışma kapsamında dijital oyun ile ilgili araştırmalar, içerik açısından ve bibliyometrik olarak irdelenmiştir. Yapılan incelemenin sonucu olarak ilgili alana ilişkin genel eğilimler, çalışma yapan yazarlar ve çalışmaların yıllara göre tasnifi gibi nitelikler görsel haritalarla gösterilmiştir. Verilerin elde edilmesinde, Web of Science (WoS)’tan faydalanılmıştır. “Digital game” terimi taratılarak gerçekleştirilen araştırmada toplam 920 yayına ulaşılmıştır. Verilerin analizinde, içerik analizi ve bibliyometrik analiz kullanılmıştır. Araştırmada, WoS’ta yer alan çalışmaların yıllara göre dağılımının 2004-2022 yılları arasında, en üretken yazarın ise Gwo-Jen Hwang olduğu sonucuna ulaşılmıştır. İlgili konuda en çok yayın yapan üniversitenin “National Taiwan University of Science and Technology”, en çok yayın yapılan ülkenin ise Amerika olduğu belirlenmiştir. Ortak kelime analizine göre araştırmalarda en sık tekrarlanan anahtar kelimenin “Digital game-based learning”, ortak atıf analizine göre en çok atıf alan yazarın ise Prensky olduğu sonucuna ulaşılmıştır. Ortak yazar analizi sonucunda, yazarların küçük gruplar hâlinde çalıştıkları ve yazarlar arasında çoklu bağlantıların olmadığı görülmüştü
