Öğe Türü: Öğe , Öğe Türü: Öğe , Investigation of near fixed points, near fixed interval ellipse and its equivalence classes(Erdal Karapınar, 2025) Joshi, Meena; Tomar, Anita; Zubair, Sumaiya Tasneem; Mukheimer, Aiman; Abdeljawad, ThabetThe objective of the manuscript is to employ the Hardy-Roger contraction to determine the near fixed point and its unique equivalence class in the context of the b −interval metric space. Further, an improved b −interval metric variant of a quasi-contraction characterizing the completeness of a b − interval metric space is exhibited. Various illustrations have been provided to show the existence of a near fixed point and its distinct equivalence class for both continuous and discontinuous maps developed in the b −interval metric space. As an application of the b −interval metric, a near-fixed interval ellipse and its unique equivalence −class are introduced to study the geometry of non-unique nearfixed points.Öğe Türü: Öğe , Analysis of Price Bubbles in Borsa İstanbul (Bist) Liquid Banking Sector Stock Market(Sciendo, 2025) Topçu, MuratThe study investigates the stock price bubbles of the liquid banking sector index (XLBNK) and its six constituent banks in the BIST primary sector. Price bubbles are one of the important factors that trigger financial crises. Detection of bubbles in the financial sector serves as a warning for preventing crises and developing preventive policies. The GSADF test method developed by Phillips, Shi & Yu (2015) is used to analyze bubbles. The results show that there has been a structural break in the value of the Turkish XLBNK index and its component stocks since the last quarter of 2021, and more than one bubble has formed. However, there is no statistical evidence of a bubble in the share values of Halk Bank, a component of the XLBNK index. Regarding bubble formation, the structural break in the XLBNK index and shares since the last quarter of 2021 reflects the inconsistency and structural breaks in Turkey’s macroeconomic indicators and monetary policy. The observed bubbles in the share pricing of the XLBNK index and its component banks continued to persist in the third quarter of 2024 when the study was conducted. The revelation that bubbles persist in the current situation contributes to the convergence of asset prices to intrinsic prices through investor decisions, the consistent formation of asset pricing, and the effective functioning of the markets. Regarding portfolio management, the results can be used in making profit realization decisions by removing persistent stocks from the portfolio, reducing portfolio risk, and supporting investment decisions.Öğe Türü: Öğe , Transformation of television and movie watching experiences in the age of digital platforms(IGI Global, 2025) Saltik Duvan, RabiyaThe present study aims to explore and discuss the transformation of movie and TV series viewing experiences in the digital age. The study sought to address the following research questions: why are digital platforms preferred over traditional channels, and how do internet-based digital viewing platforms transform viewing habits? The study adopted a qualitative research model, conducting in-depth interviews with ten participants who expressed a preference for digital platforms over traditional ones. The data set obtained was subjected to content analysis. The analysis yielded several key reasons for the preference for digital platforms over traditional platforms, including independence from time and space, the presence of original storylines and non-cliched content, the absence of advertisements, and content diversity and personalised options. Furthermore, it was determined that viewing behaviours in the digital age encompass individual viewing, multi-screen viewing, binge viewing, genre-oriented selective viewing and content-driven viewing focused on new content.Öğe Türü: Öğe , Determining the Mediating Role of Energy Conservation on the Effect of Social Marketing on Green Organizational Behavior(Econjournals, 2025) Başal, Murat; Karalinç, Turgay; Şarkbay, Ömer Faruk; Bekun, Festus VictorThe concern for development and economic continuity leads businesses to uncontrolled growth. Organizations that try to offer the expectations of consumers with the most appropriate goods and services think that they should operate responsibly as well as being socially sensitive. Businesses that act in an environmentally friendly and environmentally sensitive manner engage in green organizational behavior. In this direction, they are in an effort to save energy by using less energy. In line with all these the present study aims to determine the mediating role of energy saving in the effect of social marketing on green organizational behavior. In this context, the sample consisting of health institutions operating in the service sector in Istanbul was determined. A questionnaire form consisting of scales was applied in order to collect the data required for the analysis of the process. As a result of the factor analysis, their validity was determined. As a result of the analysis in the statistical program, it was found that social marketing has an effect on green organizational behavior and energy saving plays a mediating role in this process. In line with these results obtained in a positive direction, such activities to be carried out by businesses are effective in the service sector.
