The relationship between leader and followers plays a vital role, particularly in educational institutions where a keen understanding of human character and high level of social interaction ought to be facilitated. For this reason, in stark contrast to contemporary leaders who see people only as units of production or expendable resources in a profit and loss statement, servant leadership focuses on meeting the needs of followers, making them reach their maximum potential and so perform optimally in order to achieve organizational goals and objectives. This study examines the effects of servant leadership behaviors of private college principals on teachers’ organizational citizenship behavior and job performance. Using 300 respondents from the private education institutes in Turkey, servant leadership behavior is examined for its indirect effects on organizational citizenship behavior and job performance by its impact on organizational justice. Organizational justice acts as a mediator between the variables in question. All the results are in support of the studied mediation effects. Implications of the findings and suggestions for future research are discussed.

This study aims to investigate the mediation effect of green product and green process innovation by focusing on the role of internal and external environmental orientation over firm performance to expand researches on environmental orientation. With this aim, a conceptual model has been recommended by unifying institutional theory and natural resource-based view. Data collected from 315 firms who have ISO14001 Environmental Management Certificate and took part in Turkey’s first and second ISO 500 Industrial Enterprises list in 2018 have been tested by using SmartPLS 3 software as part of Structural Equation Modelling. Empirical proofs show that internal and external environmental orientation has a positive effect on both green product innovation and green process innovation. Additionally, it has been concluded that internal environmental orientation has a direct positive effect on firm performance, while external environmental orientation has an indirect effect, which is through green product and green process innovation. The reason could be rooted in the ecological responsibility feeling of internal environmental orientation. External environmental orientation, though, could be limited only with fulfilling legal requirements with legitimacy acquiring desire. Firms strategically directed to the green product and green process innovation by doing more than the laws require and taking the lead could increase their firm performance. These findings contribute to theory and practice, enriching our understanding of how two dimensions of environmental orientation affect firm performance.  

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 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.

This research aims to investigate the relation of the innovation types such as service innovation, process innovation and management innovation with the performance. Additionally, this study will also focus on whether there is a mediator role of technological capability and organizational learning on performance. The research data were collected from 306 principals and teachers working in medium-large scaled high schools in Istanbul. The research results showed that, as hypothesized, the types of innovations significantly correlated with the performance. Besides, organizational learning and technological capability had partially a mediating effect in the relationship between the innovation types and performance.

Artificial intelligence (AI) is a rapidly developing technological development that helps individuals in many areas. However, this progress is met with different reactions from individuals. The paper aims to investigate the associations among the concepts of spiritual intelligence, intolerance of uncertainty and AI anxiety. Furthermore, mediating role of intolerance of uncertainty on the relationship between spiritual intelligence and AI anxiety is another aim to examine in this study. In order to measure the mentioned variables, data was collected from 382 white-collar employees using survey method. We conducted explanatory and confirmatory factor analyses to control validity, and Crombach Alpha values to control reliability of the scales. Findings represented that each scale was valid and reliable. After that measurement model and structural equation modelling was conducted for model testing. The results represented the significant relationship between spiritual intelligence and intolerance of uncertainty, between uncertainty tolerance and AI anxiety (also its dimensions). In addition, findings showed that intolerance of uncertainty fully mediates the relationship between spiritual intelligence and learning of AI anxiety, also between job replacement of AI anxiety. Furthermore, results presented that intolerance of uncertainty partially mediates the relationship between spiritual intelligence and sociotechnical blindness and configuration of AI anxiety.

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).

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.
