Abstract
This paper seeks to evaluate consumption-based poverty in Türkiye between 2003 and 2022. Using representative household data from the Turkish Statistical Institute’s Household Budget Survey, this study calculates the Foster-Greer-Thorbecke (FGT) poverty indices based on relative poverty thresholds. The results show that poverty rates initially declined rapidly between 2003 and 2008, increased slightly between 2008 and 2012, and then continued to decline between 2012 and 2018. After 2018, poverty rates increased in Türkiye, almost reaching the 2007 level. The analysis also includes the decomposition of poverty changes into growth and redistribution components as well as subgroups. Growth in living standards acted as a poverty-reducing effect and was dominant between 2004-2008 and 2012-2018. The redistribution component was a poverty-increasing factor that was dominant after 2018. These periods coincide with the country’s overall economic performance. In particular, the highest decline in poverty rates occurred during high economic growth between 2003-2008. The surge in inflation post-2019 aligns with the increase in consumption poverty rates in 2022.

Abstract
The environmental damage caused by increasing population, intensifying industrialization, and excessive consumption has reached threatening levels for human life. Promoting sustainable consumption behaviors and transforming existing consumption behaviors into sustainable ones is of great importance for the efficient use of resources and the reduction of environmental damage. Measuring individuals’ perceptions and tendencies toward sustainable consumption will enable institutions and organizations to transform current consumption behaviors and develop the necessary strategies to achieve their goals. The purpose of this study is to adapt the sustainable consumption scale developed by Quoquab and Mohammad (2020) to Turkish by examining its validity and reliability. The items in the original scale were translated into Turkish using a translation-back translation method. The translated scale was applied to 485 individuals selected using a convenience sampling method. Data analysis began with item-total correlation analysis, followed by exploratory factor analysis (EFA) using the parallel analysis method. The three-factor structure with 16 items obtained from EFA was examined with confirmatory factor analysis (CFA) to achieve a valid measurement model. The three factors explain 58.12% of the total variance. The internal consistency coefficient (Cronbach’s alfa) for the entire scale was calculated as 0.87. The resulting model was tested for discriminant and convergent validity. The findings indicate that the Turkish form of the scale is a valid and reliable measurement tool. The adapted scale is expected to contribute to future studies measuring the sustainable consumption tendencies of Turkish consumers.

Abstract
The objective of this study is to investigate the mediating influence of continuance commitment on the effect of psychological contract breach on turnover intention. These relationships were established in accordance with the tenets of social exchange theory and conservation of resources theory. The data for this study were collected from employees of a district municipality in the TR82 region using a cross-sectional research design. The data were analysed using statistical methods. The findings of the study indicate that psychological contract breach exerts an influence on turnover intention; however, continuance commitment does not mediate this effect. This study is anticipated to contribute to the existing literature within the framework of social exchange theory and resource conservation theory, and to raise awareness about psychological contract breach. It also aims to contribute to organizations to develop strategies to increase continuance commitment and retain talent.

Abstract
As Bitcoin’s popularity has grown, scaling issues have inevitably emerged. Limitations on block size and increasing transaction fees have sparked debates and triggered the search for alternative solutions. Ethereum was designed to surpass Bitcoin’s limited functionality and provide more complex features such as smart contracts. However, the widespread adoption of Ethereum has led to challenges in sustaining increased transaction volumes without compromising on speed and/or cost. In response to these difficulties, layer-2 scaling solutions like Optimistic Rollup have been developed. This study examines the scalability challenges of the Ethereum network and assesses the impact of layer-2 scaling solutions, specifically Arbitrum and Optimism, on scalability. According to the study’s findings, the activation of Arbitrum and Optimism results in an increase in both daily average transaction numbers and average transaction fees on Ethereum. These findings indicate that layer-2 solutions like Arbitrum and Optimism have not been successful in enhancing Ethereum’s scalability and reducing transaction costs as originally envisioned.

Abstract
This study aimed to forecast drinking water sales accurately for a water company dealer using the artificial neural networks method. The data used in this study is the total monthly sales number of dispenser-size water bottles of a water company’s dealer in Bursa. The data consists of 85 months, from May 2017 to May 2024. In this context, an artificial neural network model was developed, and the estimations’ performance was quite good. The histogram of estimation errors and normality tests showed a normal distribution. The findings show that the network can generalize. Besides this, visualizing the actual and estimated values showed that they follow the same patterns. As a result, it was concluded that monthly sales can be forecasted with the model developed using the threshold values and weights obtained from the trained network. Long-term forecasts were made and interpreted for the water company dealer using the developed model. Finally, the proposed artificial neural network was validated by comparing it with the average absolute percentage error values of alternative models, seasonal autoregressive integrated moving average, and seasonal exponential smoothing models.

Abstract
Financial development, defined as the growth of all elements within a financial system, can have an impact on various macroeconomic factors. Funds raised through financial development can be used to finance new investments needed for economic growth. As a result, new tax jurisdictions are created, and tax revenues increase. The aim of this study is to explore the causality relationship between financial development and tax revenues in Türkiye using up-to-date methods. Annual data on Türkiye’s financial development index and tax revenue/GDP ratio for the period 1985-2021 are used. In order to determine the relationship between financial development and tax revenue, firstly, the stationarity of the series is analyzed using the two-break Narayan-Popp unit root tests that take structural breaks into account. Then, the existence of a causality relationship is analyzed using Hatemi-J asymmetric causality tests. According to the unit root test results, the series is stationary when the first difference is taken. According to the findings of the Hatemi-J test, there is no causality relationship from all shocks of financial development to all shocks of tax revenues, when the other direction of causality is analyzed, it is concluded that there is no causality relationship from all shocks in tax revenues to all shocks in financial development.

Abstract
This research examines the dynamic relationship between economic policy uncertainty (EPU) and initial public offering (IPO) volume in the United States from 1990 to 2020. Employing time-series econometric methods, we find that EPU has a significant negative effect on IPO activities. According to impulse responses, the number of IPOs significantly reacts to the innovations on EPU within the next 1 to 4 months and approaches the new equilibrium in 6 to 8 months. However, EPU does not contribute to forecast error variance decompositions of the number of IPOs. Our empirical results also show that the number of IPOs switches between low-mean/high-variance and high-mean/low-variance regimes. The results have some useful implications for timing IPOs in terms of economic policy uncertainty.

Abstract
Responsible leadership entails balancing the needs of various stakeholders, yet resource constraints and the pursuit of visible benefits for both the community and the organization pose challenges. This study proposes a methodology to identify the most essential and impactful responsibilities for leaders. Utilizing the Delphi technique, decision making trial and evaluation laboratory (DEMATEL), and analytical network process (ANP), data were collected from 40 respondents representing diverse stakeholder groups. The study first identified five major criteria through Delphi technique which included: (a) needs of the surrounding community, (b) areas with minimal government support, (c) enhancement of organizational image, (d) contribution to organizational performance, and (e) quantity of resources required. DEMATEL analysis revealed that criterion (e) was the most influential, followed by (b), (c), (a), and (d). Criteria (a), (b), and (c) acted as influencers, whereas (d) and (e) were receivers. Then, using the Delphi technique, five key responsibilities were identified: (R1) supporting children’s education, (R2) capacity building for the local community, (R3) setting up water filtration plants, (R4) improving the working environment, and (R5) reducing discrimination. ANP analysis prioritized these responsibilities according to the already identified criteria as R1, R2, R5, R4, and R3 respectively. This structured approach is expected to guide leaders in making decisions to allocate resources optimally, thereby maximizing benefits for both the organization and the community.

Abstract
Work-based learning (WBL) is an educational approach that builds a bridge between theory and practice. While there has been much study on the effectiveness and success of internships in fields like health, engineering, and teaching, there is a scarcity of studies examining how internship experiences might impact the career outcomes of business students. Based on social cognitive career theory, this study aims to explore business students’ internship experiences and their potential influence on their career resources. A qualitative research design was employed in this study. Two diverse focus group studies, which consisted of thirteen students in total, were conducted to investigate the participants’ internship experiences deeply. The findings were analyzed using thematic content analysis. Based on the results, two themes emerged: “internship satisfaction factors” and “career resources.” The findings showed that internship experiences make significant contributions to the career development process by providing vital skills, including networking, communication, and job searching, in addition to facilitating the transfer of theoretical knowledge into practice. The findings provide valuable insights for scholars and policymakers in higher education institutions and various organizations interested in establishing internship programs.

Abstract
This research investigates the impact of organizational long-term orientation (LTO) and employees’ pay satisfaction on their intentions to leave their jobs. Drawing from stewardship theory, it proposes that both organizational LTO and pay satisfaction will inversely influence employees’ intentions to quit. Furthermore, these two antecedents are expected to have an interactive influence on turnover intentions. The theoretical model was empirically tested with data collected from an online survey of 335 white-collar employees across various industries in Türkiye. The data were analyzed using moderated multiple regressions. The findings provide empirical support for the hypothesized negative relationships between both organizational LTO and pay satisfaction with employees’ intentions to leave their jobs. Furthermore, LTO has a significant moderating effect. When pay satisfaction is low, LTO significantly reduces turnover intentions. No significant effect is found when pay satisfaction is high. Hence, the study shows that pay satisfaction has a key influence on employees’ decisions to remain with the organization, especially in the context of high levels of unemployment and economic uncertainty observed in developing countries like Türkiye. Nevertheless, the study findings also suggest that organizations that have a high level of LTO can buffer at least some of the negative effects of low pay on employee retention.
