Revisiting the impacts of green purchasing practices on environmental and economic performances: A case study for the Marmara region of Türkiye
The growing global emphasis on environmental sustainability and the role of businesses in addressing climate change has highlighted the importance of integrating green purchasing practices (GPPs) into supply chain management. This study investigates the impact of GPPs on environmental performance (EP) and economic performance (ECP) in companies operating within the Marmara Region of T & uuml;rkiye, which contributes 35 % of the national GDP and houses over half of its manufacturing industry. Addressing a gap in existing literature, the study holistically evaluates four sub-activities of GPPs-supplier selection, supplier development, supplier collaboration, and supplier evaluation-and examines the mediating role of EP between GPPs and ECP. A survey was designed and conducted with 233 purchasing managers from small and medium enterprises (SMEs) and large enterprises in the region to achieve these aims. Exploratory and confirmatory factor analyses ensured the reliability and validity of constructs, while regression analysis tested hypotheses and mediating relationships. Results reveal that while GPPs significantly enhance both EP and ECP, not all sub-activities have uniform effects. Notably, EP partially mediates the relationship between GPPs and ECP, demonstrating that environmental improvements can offset initial costs and enhance financial outcomes. These findings provide a robust framework for addressing challenges in transitioning to GPPs in developing economies
Ecocritical Reflections: Post-Anthropocentrism in Bilge Karasu's The Prey
In his attempt to critique anthropocentrism and speciesism, Bilge Karasu, a postmodern Turkish writer, problematizes the relationship between human and nonhuman entities. In The Prey, one of the short stories in The Garden of Departed Cats (2003), Karasu employs surrealist and unnatural narrativity to disrupt the mimetic illusion considered by many posthumanist scholars as essential for the formation of new subjectivities. Through a narrative rich in figurative language and metafictional elements, Karasu engages with the complexities of species hierarchy, power relations and the redefinition of love. Surrealistically, set against the backdrop of variable weather conditions, the story questions human superiority over nature, highlighting the vulnerability and interdependence of all beings. Initially viewing the fish as a burden, the fisherman's journey parallels his childhood memory of encountering a snake, leading to a profound realization of the fish's capacity for affection and suffering. As empathy grows, so does the fisherman's ability to comprehend the language of the animal, culminating in a physical and spiritual metamorphosis upon their union. Through exploration of human cruelty and the possibility of harmony with nonhuman animals, the story highlights and subtly critiques the nature of humanity. Thus, by depicting a unification between human and nonhuman, The Prey suggests that genuine humanity lies in embracing interconnectedness and fostering equality-based relationships with the animal other
China’s Sustainable Development under Climate, Energy and Policy Uncertainty: A Focus on SDG 7 and SDG 13
This paper contributes to the literature through a focus on the case of China and an investigation into the effects that CPU, EPU, and EUI variables have upon SDG 13 and SDG 7 through using ARDL and NARDL models along with the Dynamic Multipliers Effect Test. The analysis period includes annual data from 2003 to 2022. In the case of this study, from the literature review, some readily available studies measured the impact of China’s CPU, EPU, and EUI on the SDGs. It has also been observed that the degree of investigation on the effects of CPU on SDG 13 and SDG 7 has been shallow. Based on the results, the constructed SDG 7 and SDG 13 ARDL and NARDL models strongly validate the cointegration relationships among the taken variables. The test of symmetric effects on CPU in SDG13 from the results of the NARDL shows that the coefficients for LCPUpoz andLCPUneg are positive, which means the effects of positive shocks are more dominant. Additionally, to ensure model robustness, three parametric methods—Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), and Canonical Cointegration Regression (CCR) are utilized. According to results, CPU, EPU and EUI have a substantial impact on the SDG7 and SDG13 indices. © 2025, Econjournals. All rights reserved
Examining the Relationship Between Public Offering Transactions with Investor Portfolio
Şirketlerin sürdürülebilirliğini sağlama ve yüksek finansal giderlerinin mali tablolar ile kazançlar üzerinde oluşturduğu olumsuz etkileri minimize etme amacı, şirketleri halka arz yoluyla kaynak sağlamaya yönlendirmektedir. Bu çalışmada, Haziran 2012-Şubat 2024 dönemine ait aylık veriler kullanılarak halka arz endeksi (XHARZ) ile yerli ve yabancı yatırımcıların portföy değerleri arasındaki ilişki incelenmiştir. Fourier nedensellik testi sonuçlarına göre, halka arz endeksi ile yatırımcı portföy değerleri arasında herhangi bir nedensellik ilişkisi tespit edilememiştir. Bu bulgular, yatırımcı portföylerinin yalnızca halka açık şirket hisselerini içermemesi, portföylerin tahvil, emtia ve gayrimenkul gibi farklı varlık sınıflarını da kapsayabilmesi ile açıklanabilir. Ayrıca, Türkiye’de finansal okuryazarlık oranının düşüklüğü, halka arz yatırımlarının kısa vadeli kazanç aracı olarak değerlendirilmesi ve geleneksel yatırım araçları olan altın ve dövize yeniden yönelim gibi faktörlerin de bu sonuçların ortaya çıkmasında rol oynadığı düşünülmektedir. Bu unsurlar, analiz sonuçlarının özgün yapısına ve yatırımcı davranışlarının dinamiklerine ilişkin önemli bilgiler sunmaktadır. Çalışmanın sonuçları, finansal okuryazarlık seviyesinin artırılması ve halka arz süreçlerine ilişkin stratejik düzenlemelerin gerekliliğini de ortaya koymaktadır.Ensuring corporate sustainability and mitigating the adverse impacts of high financial expenses on financial statements and earnings have prompted companies to seek funding through public offerings. This study examines the relationship between the initial public offering index (XHARZ) and the portfolio values of domestic and foreign investors using monthly data from June 2012 to February 2024. According to the results of the Fourier causality test, no causal relationship was identified between the IPO index and investor portfolio values. These findings can be attributed to the diversification of investor portfolios, which may include not only publicly traded company shares but also other asset classes such as bonds, commodities, and real estate. Furthermore, the low level of financial literacy in Turkey, the perception of IPO investments as short-term profit opportunities, and the reorientation towards traditional investment tools like gold and foreign currency are factors that may have contributed to these results. These elements provide critical insights into the unique nature of the analysis outcomes and the dynamics of investor behavior. The findings underscore the necessity of enhancing financial literacy levels and implementing strategic adjustments in IPO processes to address these challenges effectively
Adaptive trajectory tracking control of quadrotors based on trigonometric parameter estimation law
This paper proposes a trigonometric adaptive control (TAC) approach for quadrotors in order to obtain remarkable trajectory tracking performance in the presence of time-varying parameters. The stability of proposed controller is guaranteed by using Lyapunov stability theory. A square trajectory for way-point tracking and a 6-DoF under-actuated nonlinear quadrotor model with time-varying parameters have been used for numerical analysis. To better assess the performance of proposed adaptive controller on trajectory tracking, the results have been compared with those of a similar previous adaptive controller. The effectiveness of proposed adaptive controller has been provided highlighting that the lateral x and y position errors have been reduced by 75.18% and 71.86%, respectively, while the attitude (pitch, roll and yaw) errors have been reduced by 75.87%, 74.72% and 98.32%, respectively. Additionally, the altitude (z) error has been minimised by 37.89%. The most remarkable result to emerge from this study is that better trajectory tracking performance has been obtained by proposed adaptive controller without causing chattering phenomenon. Furthermore, the results demonstrate that the attenuation of disturbance inputs on the responses has been achieved
Three dimensional finite difference analysis of key parameters affecting the stability and the performance of nailed walls
The design and performance of nailed walls are considerably affected by many various factors such as the complex interaction between soil-nail-facing or restrictions of the constitutive models. Conventional approaches often overlook these problems and only provide some guidance in manuals, but their coverage may be insufficient. Numerical simulations are often performed to comprehend such effects in current practice. This research utilizes advanced 3D numerical methods and calibrated constitutive models to address these key issues: (i) the influence of bearing plate and facing material on factor of safety and nail forces (ii) the prediction accuracy of Federal Highway Administration (FHWA) simplified design chart and the numerical analyses (iii) the limitations of linear and nonlinear constitutive strength models when used with strength reduction procedures. To summarize, for steep slopes the existence of bearing plate and facing material within the numerical model significantly increase the safety and axial nail forces, whereas influence the failure modes and mobilized surfaces; FHWA the simplified method overestimates the nail loads particularly on the upper half of the wall and can be considered as an upper bound design envelope; linearized equivalent strength models tends to overestimate the stability of nailed slopes for rocks with low values of geological strength index (GSI) and high values of intact rock material parameter (mi). © 202

Null Hybrid Curves and Some Characterizations of Null Hybrid Bertrand Curves
In this paper, we investigate null curves in R24, the four-dimensional Minkowski space of index 2, utilizing the concept of hybrid numbers. Hybrid and spatial hybrid-valued functions of a single variable describe a curve in R24. We first derive Frenet formulas for a null curve in R23, the three-dimensional Minkowski space of index 2, by means of spatial hybrid numbers. Next, we apply the Frenet formulas for the associated null spatial hybrid curve corresponding to a null hybrid curve in order to derive the Frenet formulas for this curve in R24. This approach is simpler and more efficient than the classical differential geometry methods and enables us to determine a null curve in R23 corresponding to the null curve in R24. Additionally, we provide an example of a null hybrid curve, demonstrate the construction of its Frenet frame, and calculate the curvatures of the curve. Finally, we introduce null hybrid Bertrand curves, and by using their symmetry properties, we provide some characterizations of these curves
Does ESG performance have an impact on financial performance? Evidence from Turkey
PURPOSE: Stakeholders such as consumers, nongovernmental organizations, and public institutions have increasingly pressured companies to adopt corporate social responsibility (CSR) policies. This trend has led to the integration of environmental, social, and governance (ESG) reporting into business strategies to achieve long-term competitive advantages and enhance financial performance. ESG reporting has become a critical tool for measuring corporate CSR efforts, contributing to the institutionalization of nonfinancial reporting standards. This study aims to determine how the adoption of ESG sub-dimensions affects the financial performance of companies in Turkey. METHODOLOGY: The study employed panel regression analysis on data from 21 companies listed in the Borsa Istanbul-100 index over the period 2011-2020 to investigate the relationship between ESG sub-dimensions and firm performance. FINDINGS: The findings indicate that adopting the environmental and governance sub-dimensions positively affects ROE and Tobins'Q. However, the adoption of the governance sub-dimension negatively impacts Tobins'Q while positively influencing ROE. No statistically significant results were found regarding the impact of ESG sub-dimensions on firms' ROA ratios. IMPLICATIONS: The results of the research, based on the example of Turkey, are important to determine how companies' social responsibility strategies in developing countries provide them with outputs in terms of environment, social and governance and whether social responsibility-based activities are truly sustainable strategy for companies in developing countries.The findings highlight the importance of considering the macroeconomic structure, legal system, and financial development of countries when evaluating CSR activities. The regulatory environment plays a significant role, as weaker legal protections can negatively affect the relationship between governance practices and firm performance. For practitioners, the insights suggest prioritizing environmental investments and carefully strategizing governance practices to align with investor expectations and regulatory frameworks. ORIGINALITY AND VALUE: By focusing on the BIST 100 companies, this study contributes to the limited literature on the role of ESG sub-dimensions in shaping financial performance in developing markets. This research provides valuable insights into how environmental, social, and governance practices specifically impact the financial outcomes of firms in Turkey, offeringa nuanced understanding that can inform both academic discussions and practical strategies in similar contexts
