Spatial econometric analysis of the ecological footprint of European countries
(Istanbul University Press, 2024) Demirci, Beyda; Yerdelen Tatoğlu, Ferda
This study explains the effects of various economic factors on the ecological footprint of 34 European countries in 2022 using spatial econometric techniques. Unlike previous studies on the ecological footprint, this study presents more comprehensive results by including spatial effects in the model using spatial econometric techniques for 34 countries for 2022. This study analyzes the lagged effects of per capita GDP growth, trade openness, and renewable energy use on the ecological footprint. The spatial Durbin Model was confirmed as the most appropriate through diagnostic tests and selection criteria. The results show that per capita GDP growth, trade openness, and renewable energy usage positively and significantly affect the ecological footprint. Additionally, the spatially lagged per capita GDP growth rate has a negative impact on the ecological footprint, while the spatially lagged trade openness has a positive impact, both of which are statistically significant. These findings underscore the importance of considering the environmental impacts of economic policies to of spatial effects in the spread of ecological footprints highlights level but also in relation to neighbouring countries.

A multi-frequency iterative method for reconstruction of rough surfaces separating two penetrable media
(Institute of Electrical and Electronics Engineers Inc., 2024-12-18) Sefer, Ahmet; Yapar, Ali; Bağcı, Hakan
A numerical scheme that uses multi-frequency Newton iterations to reconstruct a rough surface profile between two dielectric media is proposed. At each frequency sample, the scheme employs Newton iterations to solve the nonlinear inverse scattering problem. At every iteration, the Newton step is computed by solving a linear system that involves the Frechet derivative of the integral operator, which represents the scattered fields, and the difference between these fields and the measurements. This linear system is regularized using the Tikhonov method. The multi-frequency data is accounted for in a recursive manner. More specifically, the profile reconstructed at a given frequency is used as an initial guess for the iterations at the next frequency. The effectiveness of the proposed method is validated through numerical examples, which demonstrate its ability to accurately reconstruct surface profiles even in the presence of measurement noise. The results also show the superiority of the multi-frequency approach over single-frequency reconstructions, particularly in terms of handling surfaces with sharp variations.
Assessing ChatGPT's accuracy in dyslexia inquiry
(Institute of Electrical and Electronics Engineers Inc., 2024) Eroğlu, Günet; Harb, Mhd Raja Abou
Dyslexia poses challenges in accessing reliable information, crucial for affected individuals and their families. Leveraging chatbot technology offers promise in this regard. This study evaluates the OpenAI Assistant's precision in addressing dyslexia-related inquiries. Three hundred questions commonly posed by parents were categorized and presented to the Assistant. Expert evaluation of responses, graded on accuracy and completeness, yielded consistently high scores (median=5). Descriptive questions scored higher (average=4.9568) than yes/no questions (average=4.8957), indicating potential response challenges. Statistical analysis highlighted the significance of question specificity in response quality. Despite occasional difficulties, the Assistant demonstrated adaptability and reliability in providing accurate dyslexia-related information.
Scenes from the mind of an artist (M Train)
(Bentham Science Publishers, 2023-11-12) Özdem, Gökçe
Patti Smith's M Train resembles a mental train that stops at any station, at any time interval. With ambition and inspiration, Smith takes the reader on a journey between dreams and reality, past and present, books and country. Smith's whole life can be considered a work of art. She is an unconventional artist who reveals herself in her relation to space. In an intertwined experience of time and space, we find Smith reminiscing on life, loss, and pains of creation. Smith's analogy of a clock with no hands refers to a frozen time, a memory where the past and the present coexist. This memory also contains the ties that a person establishes with their physical environment. The subjectivity of experience creates differences in the perception of a space. But how is it possible to resist time in our age of speed? This is what Smith presents to her readers: an infinite present. Smith's memory resists its loss, just as architecture resists time. Architecture witnesses personal and social tragedies and freezes them in time. In this sense, architecture turns into a memory remnant, a trace, and survives by creating a bridge between the past, present, and even the future. Smith's experience of the past in the present also makes it possible to interpret the relationship between architecture and experiential time. In this context, architecture reveals memory space and becomes an important factor in the reproduction of memory. Moreover, it can help revive and maintain memory by constructing new forms of expression. In this regard, personal and social memory emerges as a subject that should be emphasized in architectural research.
