Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Assessment of mitogen-activated protein kinases as therapeutic targets for the treatment of babesiosis and theileriosis
No full textThe Piroplasmida order comprises parasitic protozoa including the Theileria and Babesia species that are transmitted by vector ticks and can cause severe diseases in domestic and wild animals. Because of limited therapies and available drug resistance, the discovery of new, effective, and safer drugs for veterinary use is important. Mitogen-activated protein kinases (MAPK) are a group of serine-threonine protein kinases found in diverse species, including animals and protozoa that conduct vital cellular functions. Therefore, they have been at the centre of drug design studies for many years. Computer-aided structure-based drug design is a fast and effective way in drug discovery efforts to identify candidate compounds. In this study, we conducted comparative sequence analysis of MAPK proteins from the Theileria (T. annulata, T. parva., T. orientalis, and T. equi) and Babesia species (B. bigemina, B. microti, and B. bovis). Three-dimensional protein structures from relevant species (T. annulata and B. bovis) were modelled and compounds were screened for interaction. Results showed that the inhibitors designed for human use could also be potent against Prioplasmida MAPKs. Furthermore, the structural differences between Prioplasmida and mammalian MAPKs could be a way for researchers to better instigate selective drug design
Recent and future innovations in the treatment of heart failure [Kalp yetersizliǧi tedavisinde yeni açılımlar: Şimdi ve gelecek]
No full textHeart failure is still an important public health problem despite important advances regarding its treatment. Several new treatment strategies are being investigated in order to contend with this disease. Strategies proved to be safe and effective in clinical trials are being adapted to clinical practice. In this review, we will first focus on most recent treatment strategies that are recommended to be used in clinical practice and then try to mention novel strategies which are still being explored in preclinical studies. © 2013 by AVES Yayincilik Ltd
Improving the surface quality of TI6al4v parts produced by Additive manufacturing with magneto electro polishing
No full textEklemeli İmalat teknolojisi, prototip üretiminin yanında düşük adetli fonksiyonel parçaların üretilebilmesi için en uygun yöntem olarak kabul edilmektedir. Eklemeli imalat ile geleneksel yöntemlerle üretilmesi mümkün olmayan veya karmaşık iç unsurları olan parçalar yapılabilmektedir. Polimer, seramik veya metal gibi çok değişken materyallerin kullanılabilmesi bu teknolojiye olan ilgiyi daha da artırmıştır. Bu çalışmada Eklemeli İmalat ile Ti6Al4V metal alaşımı kullanılarak üretilen deney parçalarının yüzey kalitesinin iyileştirilmesi hedeflenmiştir. Bu araştırmada uygulanan yöntem olan Elektro-Parlatma, anot katot ve elektrolit kullanımını içeren elektrokimyasal yüzey aşındırma işlemidir. Manyetik etki altında yapılan Elektroparlatma işlemi ise Magneto-Elektroparlatma (MEP) olarak tanımlanmıştır. Bu çalışmada mevcut araştırmalara katkı sağlamak için EP ve MEP deney düzenekleri hazırlanmış ve Ti6Al4V alaşımı ile üretilen parçalara bu işlemler uygulanmıştır. Standart EP ile MEP karşılaştırılarak MEP işleminin standart EP ye göre daha iyi sonuç verdiği yapılan ölçümlerle belirlenmiştir. Karmaşık geometriye sahip parçalara uygulanan MEP işleminin diğer fiziksel ve kimyasal yöntemlere kıyasla daha düzgün yüzey formu oluşturduğu gözlenmiştir.Additive Manufacturing technology is considered the most suitable method for producing lowvolume functional parts as well as prototype production. With additive manufacturing, parts
that cannot be produced using traditional methods or parts with complex internal elements can
be made. The ability to use very variable materials such as polymer, ceramic or metal has further
increased the interest in this technology. In this study, it was aimed to improve the surface
quality of test pieces produced using Ti6Al4V metal alloy with Additive Manufacturing.
Electropolishing, the method applied in this research, is an electrochemical surface etching
process that involves the use of anode, cathode and electrolyte. The electropolishing process
performed under magnetic influence is defined as Magneto-Electropolishing (MEP). In this
study, in order to contribute to existing research, EP and MEP experimental setups were
prepared and these processes were applied to parts produced with Ti6Al4V alloy. By comparing
standard EP with MEP, measurements have shown that the MEP process gives better results
than standard EP. It has been observed that the MEP process applied to parts with complex
geometry creates a smoother surface form compared to other physical and chemical methods
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
Review of Liquefaction Around Marine Structures by B. Mutlu Sumer
No full textOwing to the growth of activities in the marine environment, the phenomenon of fluid–soil structures around marine infrastructures has attracted great attention among coastal and geotechnical engineers. Seabed liquefaction is one of the key failure mechanisms around marine installations such as breakwaters, pipelines, platforms, and offshore wind turbine foundations. Therefore, evaluation of the seabed instability around marine structures is particularly important for engineers involved in the design of foundations of marine infrastructures.No Full Tex
