In this study, Banca Etica, which operates in Europe within the scope of ethical banking practices, and participation banks in Turkey were compared in terms of business ethics. Ethical banking is an approach based on observing social, environmental and ethical responsibilities in the provision of financial services. Banca Etica and participation banks apply these ethical principles in different ways. Banca Etica focuses on social and environmental sustainability, transparency and community participation. The bank offers its customers interest rates determined in line with ethical principles and invests in social responsibility projects. Drawing attention with its transparency and accountability policies, Banca Etica regularly reports the effects of its investments and loans and shares them with the public. Participation banks in Turkey adopt interest-free banking principles in accordance with Islamic finance principles. These banks, which serve their customers by offering profit-loss sharing models and products that comply with Islamic finance rules, focus on social responsibility projects such as social justice and helping the poor. Participation banks' transparency regarding sharia compliance assures their customers that their transactions comply with Islamic finance rules. As a result, both types of banks operate in line with ethical principles, but their implementation approaches and areas of focus differ. These differences determine customers' preferences and banks' contributions to society and the environment.

This paper portrays the literature on voluntary corporate disclosure via social media networks over the course of two decades (2002-2022) through a content analysis framework. Focusing on papers in English, Turkish and Arabic, it reviews a total of 65 studies from 15 countries, based on number of posts, type of information disclosure, time span and social media platforms used. Additionally, it provides a detailed break-down of the reported effect between voluntary disclosures on social media and a total of 37 different variables used to proxy for market, accounting, corporate governance and firm-specific (size, age and risk) measures. Drawing from an exhaustive analysis encompassing more than 51 thousand companies and nearly 70 million social media posts, the prevailing body of knowledge pertaining to corporate disclosures via social media predominantly hinges upon empirical evidence based on the United States and the United Kingdom. We feel that more country comparison studies and multi-lingual samples as well as meta-analyses could significantly improve our understanding of this field.  

Service quality is crucial for all service providers operating in the open market across all industries, particularly in the aviation sector, which produces billions of dollars in annual revenue from its services. The level of service quality significantly influences client satisfaction, and conversely, customer happiness reciprocally affects the service provider. In order to attain diverse company objectives, it is imperative to prioritize customer happiness specifically during the process of privatization. The primary objective of this research is to examine the influence of airport service quality on customer satisfaction within the context of a privatized airport. Descriptive and correlation analyses were utilized in the study. A total of 400 questionnaires were administered to passengers who embarked from Aden Adde International Airport as part of the study. Subsequently, the data was subjected to analysis utilizing a statistical software program designed for social science software (SPSS). The results of this analysis revealed a robust and positive correlation between Airport customer services and customer happiness. The study additionally revealed that a significant proportion of the airport's passengers expressed dissatisfaction with the services provided by Aden Adde International airport. 

In the pursuit of academic excellence, scholars are dependent on trustworthy journals to disseminate their research and contribute to the collective body of knowledge. However, the academic community is not immune to deceptive practices. This letter highlights the case of the "Global International Journal of Innovative Research," where my name, along with esteemed colleagues, was falsely associated with the editorial board without consent. Despite repeated efforts to address this issue, the journal remains unresponsive. This letter announces our intention to publish an exposé article, meticulously uncovering the fraudulent practices of the journal and its publisher. A subsequent public statement aims to warn the academic community about the deceptive nature of the "Global International Journal of Innovative Research" and emphasizes the collective responsibility of scholars to uphold ethical publishing standards. Through this exposé, we hope to safeguard the integrity of academic pursuit and raise awareness about the risks associated with engaging with predatory journals.

In recent years, the aviation industry has transformed significantly, driven by the increasing importance of digital technologies and social media for communication and marketing. The COVID-19 pandemic accelerated this transformation, posing unprecedented challenges to airlines. The present study investigates how Turkish Airlines, Qatar Airways, and Emirates adapted their social media strategies before, during, and after the pandemic. The research has a threefold focus: (i) assessing pre-pandemic social media strategies, (ii) examining strategy evolution during the pandemic, and (iii) comparing the effectiveness of these strategies before and after COVID-19. By exploring how these airlines leveraged social media to navigate pandemic-related disruptions and maintain vital connections with passengers, this study provides valuable insights. These findings hold significant implications for aviation stakeholders, marketing professionals, and researchers, shedding light on the evolving role of social media in crisis communication and marketing. The study uncovered interesting changes in how airlines use Twitter. After the pandemic, they started using more emojis, and their messages shifted from promoting services to expressing hope during the pandemic and back to promotions afterward. They played with visuals and hashtags. Pricing-wise, they offered discounts for students, different ticket options, and bundled services. In promotions, they focused on being environmentally and socially responsible, user convenience, and specific events. They mainly shared updates on flights, achievements, and travel advice. To engage people, they used quizzes, replied directly to customers, and targeted specific groups. For marketing managers, the study suggests being more customer-focused, emphasizing environmental and social responsibility, offering diverse pricing, celebrating milestones, and creating engaging content. Overall, the findings provide practical insights for adjusting marketing strategies in the ever-changing world of airlines, especially considering the challenges brought by COVID-19.

This study was conducted to determine the relationship among individuals' innovative competencies, management innovation, and organizational performance. This quantitative study was conducted with 531 business employees operating in various sectors at national and international levels, and the survey method was preferred as the data collection tool. The developed hypotheses within the scope of the study were tested by using Statistical Package for the Social Sciences (SPSS). As a result, significant findings were obtained in the relationship and impact analysis dimensions among innovation competencies, management innovation, and organizational performance. The results depict that innovation competencies and management innovation have a positive and significant effect on organizational performance (?=0.470, p<0.01; ?=0.503, p<0.01, respectively). Additionally, it was concluded that management innovation has a positive and significant mediating effect on the relationship between innovation competence and organizational performance (?=0.175; p<0.01).

Aviation-oriented companies are continuously seeking innovative approaches to enhance the passenger experience and operational efficiency within the industry. The objective of this study is to evaluate the categorization of passengers' technological preferences in Turkish airports. The objectives of this study are to enhance the understanding of Aviation Companies in Turkey regarding the technology preferences of passengers and their fundamental needs, as well as to analyze the characteristics of passengers that are directly linked to their technological choices.  This study employs purposive sampling with a sample size of 455. Various statistical techniques, such as regression, correlation, and descriptive statistics, are employed to analyze the data. The findings indicate that biometric technology, personal device utilization, customisation and customization, as well as streaming and on-demand entertainment, greatly influence the technological preferences of travelers. Nevertheless, contactless solutions, inflight Wi-Fi, and mobile apps and digital services do not influence the technological preferences of travelers.

The banking system’s role as an intermediary between depositors and borrowers makes its stability a crucial element of the economy. Individual bank stability impacts the stability of the financial sector and, consequently, the real sector and economic growth. This study is a detailed investigation of bank stability scores for the Turkish banking sector. Turkey experienced a major banking crisis from 2000 to 2001. However, with an improved regulatory environment and structural reforms, its resilience to shocks increased significantly in subsequent years. The present study contributes to the literature in three areas. First, it applies eight variations of the Z-score to the Turkish banking sector to test the importance of time and risk variation. Second, it investigates the impact on stability scores of several factors–the implementation of new capital regulations and Basel III liquidity rules, the Turkish lira crisis and the effects of COVID-19). Finally, it measures the contribution to systemic risk of each Turkish bank using the leave-one-out (LOO) Z-score method; this is the first study to use this method to analyse the contribution of different bank types to the overall stability of the sector.

This paper examines CSR approaches and practices of local firms in Ethiopia, where the state is still a key player in business life. Moreover, it assesses at which stage Ethiopian CSR is. This mixed-method study includes quantitative analysis through SPSS and qualitative content analysis. A revised CSR practices scale has been conducted on owners/managers and employees of 100 local companies in Ethiopia. Besides, the companies' official websites have been thoroughly reviewed using five variables to understand their CSR approaches and practices better. The findings reveal that Ethiopian companies practice CSR though it is at the stage of fragmented CSR and the priorities differ from the global trend. Most respondent companies generally have excellent legal practices and CSR practices toward employees and customers. However, philanthropy, social sustainability, and management of CSR are remarkably at a mediocre level. Content analysis shows similarity with the results of quantitative study, to the exclusion of philanthropy. Notably, the hierarchy derived from our research varies also with Visser's CSR model.

This study aims to identify the most influential blockchain types for potential implementation areas in the transforming mobility ecosystem, considering application area-specific needs such as transparency, transaction speed, scalability, energy usage, security, and operating cost. The study demonstrated the hybrid blockchain suitability for most of the 13 distinguished mobility applications, while private and consortium blockchains are found applicable based on the needs of specific use cases. A public blockchain is only found suitable for two of the use cases. Proof of Authority and Proof of Stake matches well with most use cases, while Practical Byzantine Fault Tolerance and Proof of Work could be suitable in particular.

In the past 20 years, commodity markets have been examined under the hypothesis of whether the prices exhibit recurrent patterns or follow the stochastic processes. In this study, we analyze both global energy markets and food markets to detect the presence of multiple equilibria, which may lead to higher spikes in prices and to the occurrence of intermittency. This study focuses on daily prices in Brent petrol and Natural gas markets from 23 May 2017 to 23 May 2022. This time interval covers the period where extraordinary economic and financial policies have been preferred in countries worldwide amid the Covid-19 pandemic crisis. On the other hand, the study investigates global Food index monthly data from 2007M11 to 2022M4. Similarly, the time interval under examination points out the effects of the 2008 global crisis where expansionary monetary policies have been implemented both by the Federal Reserve of the U.S and the European Central Bank. We employed the phase-space reconstruction method for the Crude oil Brent Europe and spot Natural gas prices series, and global Food index data respectively. The main findings of the study demonstrate that commodity markets do not converge to a unique equilibrium level, instead multiple equilibria persist and chaotic behavior occurs. The presence of multiple equilibria leads to an increase in complexity and recurrently causes volatility in commodity markets, which may have spillover effects on other financial markets. Our results suggest that these effects simultaneously increase global inflationary pressures. From the perspective of policy making, it is crucial to establish a strategy to eliminate multiple equilibria and prevent high price spikes. Our findings have important implications for Central bank policies in emerging markets and portfolio and risk management.

This paper aims to investigate the mediating role of explicit knowledge sharing in the relationship between empowering leadership and proactive work behavior in defense industry enterprises. The sample of this study consists of defense industry enterprises operating within the borders of Turkey. A total of 305 survey data were collected from these enterprises using the random sampling method, and 5 survey data among them were eliminated because of missing information, and analyzes were made with a total of 301 survey data. Structural equation modeling was used to test the research model and hypotheses. According to the analysis results of the study, empowering leadership has a positive effect on proactive work behavior and explicit knowledge sharing. In addition, it has been understood that open information sharing has a positive effect on proactive work behavior. Finally, it has been revealed that explicit knowledge sharing has a mediating role in the relationship between empowering leadership and proactive work behavior.

The rapid growth in civil aviation operations in recent years has raised expectations from flight attendants. Their duties have been intensified, and flight attendants have become subject to physical and mental fatigue due to irregular sleep, inadequate rest time, and long working hours. This study investigates the causes and effects of fatigue among flight attendants of a Turkish airline company through a self-administrated questionnaire. The survey is run online by 152 flight attendants. The results show that flight attendants have trouble falling asleep before flight duty. Before night flights and during layovers, the sleep duration is dramatically low. The results also reveal that factors related to scheduling, i.e., long duty days, night flights, and consecutive working days, play an essential role in fatigue. Thus, airline companies should revise their scheduling practices. In balancing work and social life, men struggle more than women, and married flight attendants have more difficulty than single ones. The findings provide valuable insights for airline companies and policymakers to seriously manage fatigue-related factors to ensure the safety of aviation operations and the well-being of flight attendants.

In this study, the relationships between cargo revenues, ancillary revenues and net profitability of airline companies were examined in the examples of three full-service airline companies (Turkish Airlines, American Airlines, Delta Air Lines). Methodologically, a logarithmic econometric model was used in which cargo revenues and ancillary revenues were included as independent variables and net profit as the dependent variables. The data used for the period 2014Q1-2019Q4 were collected from the annual reports on the official websites of related airline companies and The International Air Transport Association (IATA). EViews 10 and STATA-15 versions, which are the most modern econometric analysis programs that can be used to control the stationarity, were used in the analysis of the data. In addition to econometric analyzes and general statistics, Cross Section dependency tests, CADF second-generation unit root tests, Delta slope homogeneity tests, Panel cointegration analysis, Westerlund Panel cointegration tests and Dumitrescu Hurlin Panel Causality tests and Breusch Pagan LM Tests were also performed. The study revealed that there is cointegration between cargo revenues, ancillary revenues and net profit, and there is a one-way causality relationship from both cargo revenues to net profit and from ancillary revenues to net profit. The study also indicated a positive correlation between cargo revenues and ancillary revenues and net profit. In other words, cargo revenues and ancillary revenues have a positive effect on the net profit of airline companies. In addition, the study found that aviation ancillary revenues provide an important resource for airline companies; furthermore, two US companies are among the top three companies with the highest revenues in the world in terms of cargo and ancillary revenues; also showed that Turkish Airlines' ancillary revenues are lower than those of these two US companies. On the other hand, the study showed that the contribution of Turkish Airlines cargo revenues to net profit is much higher than the other two companies.

The Covid-19 pandemic has created a disadvantaged student population due to the sudden obligation for distance learning. Poor performance of online educational tools, risk of transmission and staying at home cause stress and anxiety in students. This research examines the effects of usability and accessibility of the online learning system on students’ anxiety in presence of students’ perceived social support as well as students’ perceived optimistic/pessimistic life orientation. The survey instrument prepared for this purpose includes questions about the online learning system used, Covid-19 anxiety, life orientation and perceived social support. Web-based questionnaires were collected from 5,682 students from different universities and the data was analyzed for the role of social support and life orientation on anxiety caused by stress born of distance learning. Findings show that accessibility has a negative effect on anxiety while the effect of perceived social support on access problems could not be ascertained. It was determined that the optimism dimension had a moderating effect on students’ anxiety and the pessimism dimension had a mediating effect. The research results are consistent with the literature.

This paper examines the concept of symbiosis in Islamic history as developed by Schlomo Dov Goitein, the 20th-century Jewish German scholar in the area of Jewish and Arabic studies, and discusses its application to the identity sourcing of Prophet Muhammad in particular. The aim of the study is to review the historical outline briefly on the background and formation of “symbiosis” preceding and in the aftermath of Goitein’s conceptualization and context, following a qualitative research approach with an intertextual criticism to his references and discussing their possible philological aspects in his mindset. The study found that, while the Islamic historical sources presented the relations between Jews and Muslims in the Madina period of Islam as negative, in Goitein’s works, the Jewish perception of early Islamic history is positively grounded on a mid-eight century Jewish messianic-apocalyptical text, namely, The Secrets of Rabbi Simon ben Yohai as traditionally understood in Judaism for describing Ishmaelites as the savior of Jews from Christian oppression.  This finding seems to be in explicit contradistinction to the concept of innovative “creative symbiosis” with subversion of historical experience.

Cash(liquidity) management is at the heart of a firm’s financial management. It is a silver lining between the bankruptcy and the success story of a company. Therefore, this study intends to contribute some insights into cash management practices and how firms can use them to achieve sound financial performance. This study provides a comprehensive literature review on existing theories and cash management practices that are useful in decision making. After the analysis of the available literature, the study highlights important theories including trade-off theory (TOT), transaction model, precautionary measures, financial hierarchy, and cash flow theory. Furthermore, management practices such as stochastic cash management model, speeding up cash collections, centralization & decentralization of management, asset portfolio diversification, and cash disbursement are discussed.  The study suggests that a sound financial performance can be achieved through a hybrid approach and through adaptation and embracing innovations in cash management systems.

In this paper studies current literature in board diversity, not specifically in gender but also ethnic, educational and cultural diversities, has been examined through their methodologies and findings. This study provides a summary of empirical findings of necessary papers in this field and try to assist researchers who are interested in this issue during their preliminary research.

The aim of this study is to determine the causality relationship between energy prices, which are among the most important inputs of the economy, and selected stock market indices of developed countries. Crude oil and natural gas are used as energy variables. G7 countries were selected to represent developed countries. Stock indices used in the study are Dow & Jones (USA), DAX (Germany), CAC40 (France), FTSE250 (England), FTSE Italia All Share (Italy), NIKKEI225 (Japan), and S&P/TSX (Canada). In the study, Johansen (1988) cointegration test and Granger (1969) causality test were used to analyse the causality relationship between energy prices and selected stock market indices. The research could not find a long-term balance relationship between energy prices and developed country indices. Also, while the causality relationship was determined between crude oil prices and NIKKEI225, DAX, and CAC40 indices, a causal relationship between natural gas prices and Dow & Jones and FTSE250 indices was determined. In the study, it was found that energy prices can be used for diversification in investments to be made with stock market indices of developed countries. This study is one of the most comprehensive studies in the literature that examines the relationship between energy prices and the stock market indices of G7 countries. It is expected to contribute to the literature in this way.
