Item Multifractal Detrended Cross-Correlations between Green Bonds and Commodity Markets: An Exploration of the Complex Connections between Green Finance and Commodities from the Econophysics Perspective(FRACTAL AND FRACTIONAL, 2024-03-08) Acikgoz, Turker; Gokten, Soner; Soylu, Abdullah BugraGreen bonds represent a compelling financial innovation that presents a financial perspective solution to address climate change and promote sustainable development. On the other hand, the recent process of financialisation of commodities disrupts the dynamics of the commodity market, increasing its correlation with financial markets and raising the risks associated with commodities. In this context, understanding the dynamics of the interconnectivity between green bonds and commodity markets is crucial for risk management and portfolio diversification. This study aims to reveal the multifractal cross-correlations between green bonds and commodities by employing methods from statistical physics. We apply multifractal detrended cross-correlation analysis (MFDCCA) to both return and volatility series, demonstrating that green bonds and commodities exhibit multifractal characteristics. The analysis reveals long-range power-law cross-correlations between these two markets. Specifically, volatility cross-correlations persist across various fluctuations, while return series display persistence in small fluctuations and antipersistence in large fluctuations. These findings carry significant practical implications for hedging and risk diversification purposes.Item The Impact On The Local Economy Of Having Coastal Areas With Blue Flag The Turkish Case(BLUE FLAG BEACHES, 2024-02-05) Eser, Zeliha; Sumer, Selay IlgazItem The İmpact Of Fluctuating İnternational Fertiliser Prices And Exchange Rates On Domestic Fertiliser Prices İn Türkiye(AGRICULTURAL ECONOMICS-ZEMEDELSKA EKONOMIKA, 2024-12-14) Bor, Ozgur; Dagistan, NihatThis study aims to examine the relationship between domestic and international prices of di -ammonium phosphate (DAP) and urea fertilisers together with exchange rates in Tiirkiye using the non-linear autoregressive distributed lag (NARDL) model on monthly data for the period of January 2011 to September 2022. The result of the study provides empirical evidence about the presence of asymmetries in the short and long -run among these fertilisers. The findings of the study confirm that international prices of di -ammonium phosphate and urea fertilisers have a symmetric effect in the long -run and exchange rate of the Turkish lira to US dollars has an asymmetric effect on the domestic prices of fertilisers in the short run. This is the first study in Tiirkiye to delineate the dynamic simultaneous interaction among these markets and its findings can be extremely useful for academicians, and policymakers to make decisions regarding the market structure of countries that do not have sufficient domestic resources for fertiliser supply and are dependent on imports.Item The Impact Of High-Performance Human Resource Practices On Subjective Career Success: The Mediating Role Of Psychological Capital And Organizational Commitment(JOURNAL OF EAST EUROPEAN MANAGEMENT STUDIES, 2024-06-19) Toyata, Berk; Kizrak, Meral; Cakar, MehmetUtilizing insights from positive psychology, social exchange theory, and social cognitive career theory, this study aims to investigate the mediating role of psychological capital and organizational commitment in the relationship between high-performance human resource (HR) practices and subjective career success. Data were collected from a sample of 429 private sector employees working on European Union projects in Turkey. Hypotheses were tested using regression, correlation, and mediation analyses, as well as Sobel test statistics. Results indicate that high-performance HR practices, organizational commitment, and psychological capital positively influence subjective career success. Additionally, there is evidence that, unlike organizational commitment, psychological capital mediates the relationship between high-performance HR practices and subjective career success. Our study underscores the need for organizations to foster and develop psychological capital among their employees to maximize the effectiveness of HR practices in promoting subjective career success.Item The Mediating Effect Of Psychological Safety On The Relationship Between Authentic Leadership And Turnover Intention(MIDDLE EAST JOURNAL OF MANAGEMENT, 2024-07-20) Durukan, Mehmet Hakan; Kibaroglu, Gamze Guner; Basim, H. NejatThis study was conducted to examine the role of psychological safety in the effect of authentic leadership on turnover intention. In this framework, from the perspective of leader-member interaction theory, it has been shown that an authentic leader can reduce turnover intention. Within the scope of the study, data were collected from 340 participants by survey method and analysed. According to the results of the research, there is an inverse and significant relationship between authentic leadership and turnover intention. In addition, while authentic leadership affects psychological safety in the same direction, psychological safety negatively affects turnover intention. In addition to these results, the most important result of our study is that psychological safety plays a mediating role in the effect of authentic leadership on turnover intention. The results of the study showed that creating a transparent work environment based on authentic leadership and establishing basic psychological safety can reduce individual turnover intention.Item Effect of Festival Satisfaction on Destination Loyalty through Destination Overall Image: The Case of Alaçatı Herb Festival(ISTANBUL BUSINESS RESEARCH, 2024-12) Ozkan, Ayse Arslan; Yildiz, ErkanThis study examines the relationships among festival success factors, festival satisfaction, destination image and destination loyalty. Based on the literature review, festival success factors were identified and a model was developed to measure the direct impact of these factors on destination loyalty and the impact of these factors through the overall image of the destination. Data were collected during the 11th Ala & ccedil;at & imath; Herb Festival held between March 24-27, 2022. The data obtained were analyzed with the structural equation modeling. According to the results of the study, the program, festival area, staff, souvenirs, and information dimensions of festival success factors affect festival satisfaction. The effects of convenience and food dimensions on festival satisfaction were statistically insignificant. The festival satisfaction and destination overall image variables have positive effects on destination loyalty, and the festival satisfaction variable has positive effects on the destination overall image. The destination overall images an integral partial mediating role in the relationship between festival satisfaction and destination loyalty.Item The Retreat From Bıst: Insıghts Into Foreıgn Portfolıo Investment Movements(EKONOMI POLITIKA & FINANS ARASTIRMALARI DERGISI, 2024-11-15) Alp, oezge S. E. Z. G. I. N.; Hazar, Adalet; Babuscu, SenolThe need for rapid growth and development in developing countries increases the demand for capital. As a result, foreign portfolio investments are of great importance, especially in emerging markets, as they help meet capital needs. However, their ability to move quickly also introduces high volatility to financial markets. This study examines changes in the share of foreign portfolio investors in Borsa Istanbul from 2004 to 2023, aiming to provide long-term insights to market participants. Initially, changes in the foreign portfolio investor ratio over time are graphically analyzed alongside the BIST 100 index and the average interest rate of deposits with a maturity of up to 3 months. These changes are evaluated in the context of both global and local developments. The study then investigates the causal relationship between the foreign portfolio investor ratio and the BIST 100 index using a cointegration test and a causality test based on the VECM model. The findings show a one-way causality from the BIST 100 index to the foreign portfolio investor ratio, indicating that foreign investors' market movements are largely influenced by the performance of the BIST 100, and local market dynamics significantly affect foreign capital inflows.Item The Moderating Role Of Paternalistic Leadership In The Relationship Between Job Satisfaction And Job Stress Among Health Workers In Gaziantep, Turkey(WORK-A JOURNAL OF PREVENTION ASSESSMENT & REHABILITATION, 2024-12-09) Tunc, Ahmet; Yagar, Sema Dokme; Gercek, Emine; Yagar, FedayiBACKGROUND: Adopting an effective leadership style is of critical importance in increasing healthcare efficiency and therefore determining patient satisfaction. For example, although there are many new and effective leadership types today, the paternalistic leadership approach can still play an effective role in developing countries. OBJECTIVE: The aim of this study is to examine the moderating role of paternalistic leadership in the relationship between job satisfaction and job stress. METHODS: A total of 466 healthcare workers completed measures of perceived paternalistic leadership, job stress, and job satisfaction. The research was conducted in the center of Gaziantep, one of the largest cities in Turkey. Regression analysis was used to evaluate the moderate variable. Dawson slope were used to visualize the results. RESULTS: A negative relationship was found between job satisfaction and job stress. Additionally, it has been determined that the perception of paternalistic leadership has a moderating role. It has been observed that as the perception of paternalistic leadership increases, the negative relationship between job satisfaction and job stress decreases. CONCLUSION: It has been concluded that the paternalistic leadership approach can play a critical role in increasing the productivity of healthcare workers and reducing the negative effect of stress on satisfaction. It has been suggested that policies be developed to develop appropriate strategies for creating work environments that will increase employees' perceptions of paternalistic leadership.Item Comparing Software Development Life Cycle Models with Multi-criteria Decision Making Approach(2024 10TH INTERNATIONAL CONFERENCE ON CONTROL, DECISION AND INFORMATION TECHNOLOGIES, 2024) Alkis-Bayhan, Nurcan; Ozmen, Esra; Karaman, ErsinVarious software development life cycle models are adopted in the software domain.
