Measuring Financial Stress in the Turkish Banking Sector and Its Evaluation in the Context of the Economic Crisis
No full textThis study develops the Turkey banking sector stress index for the period of 2012-2021. For this, sector beta, volatility, return on assets, capital adequacy ratio, and asset quality variables were used. The variables were combined with the variance equal-weight method, and a single index was constructed. The reliability of the index was evaluated in terms of whether it detects the years shown as the economic crisis years by the experts. As a result, it has been determined that the index detects the exchange rate crisis that broke out in Turkey in 2018 and the global economic crisis caused by COVID-19, the effects of which began to appear in 2020. In addition, it is predicted that there may be an increase in the number of concordats and bankruptcies in years when the stress index is high. It has been determined that the Turkish banking sector is resistant to crises.</jats:p
DOES THE IMPACT OF FINANCIAL DEVELOPMENT ON CARBON EMISSIONS DIFFER FROM DEVELOPED TO DEVELOPING COUNTRIES?
No full textThis study examined the relationship between financial development (FD) and carbon (CO2) emissions for twenty-one developed and twenty-two developing countries over the period of 2001-2020. It was seen that FD led to decreased CO2 emissions in approximately 55% of developed countries and approximately 28% of developing countries. However, in the developed and developing country panels, FD was found to cause more CO2 emissions in developed countries. It was observed that the positive effect in the panel results for developed countries came from Belgium, Denmark, South Korea and the United States, where FD led to a significant increase in CO2 emissions. These results cast doubt on the validity of the EKC hypothesis for these countries.</jats:p
Bankaların Finansal Performans ve Borç Ödeme Gücü Açısından Değerlendirilmesi
No full textBu çalışma ile bankalarının finansal performansları ve ödeme güçleri 2021-2023 yılları için TOPSIS ve Bankometer modelleri ile analiz edilmiştir. Araştırma sonucunda banka performanslarının 2022 yılında düştüğü ortaya konulmuştur. Bu düşüşün bankaların finansal varlıkları ile kullandırılan kredilerde bir azalma ve kısa vadeli yükümlülüklerde bir artış nedeniyle ortaya çıktığı görülmüştür. 2023 yılında ise banka performansları tekrar yükselişe geçmiştir. Kur korumalı mevduat uygulaması ve politika faizindeki artışla Türk Lirasına geçiş sürecinin banka performanslarına da olumlu olarak etki ettiği düşünülmektedir. Ek olarak banka performansları açısından en önemli rasyonun Likit Aktifler/Kısa Vadeli Yükümlülükler olduğu anlaşılmıştır. Ayrıca ilgili dönemlerde tüm bankaların borç ödeme güçlerinin yüksek olduğu tespit edilmiştir. Finansal performans ile ödeme gücü arasında tam bir uyumun olmadığı, ancak performans puanı yüksek olan bankaların ödeme güçlerinin de yüksek olduğu çalışmanın önemli sonuçlarındandır
Bitcoin's diversifying effect during the crisis: Evidence from the G7
No full textBu çalışmada G7 ülkelerine ilişkin hisse senedi piyasalarındaki getiri oynaklıklarının Bitcoin getiri oynaklığı üzerindeki etkileri GARCH (1 1) modeli kullanılarak araştırılmıştır. Tam veri setine ek olarak Kovid-19 öncesi dönem için alt periyot oluşturulmuş ve Kovid-19 ile birlikte piyasalar arasındaki etkileşimde meydana gelen değişimler ortaya konulmaya çalışılmıştır. Sonuç olarak ekonomik bir krize dönüşen Kovid-19 ile birlikte G7 ülke borsalarıyla Bitcoin arasındaki bağlantıların arttığı tespit edilmiştir. Ayrıca Amerika (S&P 500), Kanada (TSX) ve İtalya (FTSE MIB) getiri oynaklıklarının Bitcoin getiri oynaklığı üzerinde artırıcı; Japonya (NIKKEI 225) ve Fransa (CAC 40) getiri oynaklarının Bitcoin’in getiri oynaklığı üzerinde azaltıcı bir etkisinin olduğu ortaya konulmuştur. Bu nedenle portföylerini Bitcoin ile çeşitlendirmek ve kriz dönemlerinde risklerini azaltmak isteyen yatırımcıların ilgili borsalardaki oynaklıkları takip etmeleri tavsiye edilmektedir.</jats:p
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
