The Impact of Institutional Environment on the Asset Quality of Banks: A Study in Upper-Middle-Income Countries
No full textThe Non-Performing Loans (NPLs) are a significant indicator of asset quality in banks. In this study, the impact of the institutional environment on NPLs in upper-middle-income countries during the period of 2010-2019 is investigated using the dynamic panel data analysis method. According to the findings obtained from the analyses, institutional quality has a significantly negative effect on NPLs. The lagged value of NPLs, on the other hand, positively influences the current period's NPLs. Additionally, concerning control variables, economic growth and non-interest income negatively affect NPLs, while the credit/deposit ratio and the inflation rate have a positive impact on NPLs
Trichomes on Vegetative and Reproductive Organs of Endemic Ballota macrodonta (Lamiaceae)
No full textThe morphological features and distributions of trichomes on both vegetative and reproductive organs of endemic Ballota macrodonta were examined in this study. The species has limited distrubution in Türkiye and is endemic Iranian Turanian element. In this taxon, different trichome types were seen and these trichomes were divided into two main groups. The first group forms eglandular trichomes, the other group forms glandular trichomes. Two types of eglandular trichomes were obtained on the vegetative and reproductive organs of the taxon: simple unbranched and branched. Stellate type of branched eglandular trichomes were seen more frequently on the lower surface, margins, veins of leaves, corolla, and outer part of calyx, while long unicellular, bicellular, tricellular and multicellular types of simple unbranched eglandular trichomes were seen more frequently on all the organs of this taxon. Glandular trichomes were categorized as capitate with different stalk lengths and one–two head cells and peltate with four–eight secretory cells. According to number of stalk cells, capitate trichomes were grouped into as unicellular, bicellular, tricellular and multicellular trichomes. The capitate ones were seen nearly on all organs of B. macrodonta. Peltate trichomes were rarely found on the stem, upper surface of leaf and corolla, while these trichomes were densely found on the surface of the calyx. It was emphasized that both simple unbranched and stellate eglandular trichomes could be used as valuable characters in the classification of this species
An application of generating function for Hermite polynomials
No full textAn important application of the Hermite polynomials with the weight function absorbed into them is that they form the solutions of the differential equation for a simple harmonic oscillator. Motivated by this fact, our focus for this work is to investigate a class of singular integral equations whose kernels are formed by the generating function for the Hermite polynomials with the weighting function absorbed into them. We propose an efficient method for solving such a class of singular integral equations. In addition, we establish the results of applications involving the integral of Hermite polynomials and their generating functions

No full textBu çalışma bir eğitim ve araştırma hastanesinde görev yapan sağlık çalışanlarının paternalist liderlik davranışları ile iş performansları arasındaki ilişkide örgütsel adalet algılarının aracılık rolünü tespit etmek amacıyla gerçekleştirilmiştir. Araştırma amacı doğrultusunda veri toplama aracı olarak örgütsel adalet (aracı değişken), iş performansı (bağımlı değişken) ve paternalist liderlik (bağımsız değişken) ölçekleri kullanılmıştır. Araştırma 1387 çalışanın bulunduğu bir kamu hastanesinde, 352 kişiye ulaşılarak gerçekleştirilmiştir. Elde edilen verilerin analizi için SPSS 24, AMOS 22 ve process macro eklentisi kullanılmıştır. Ayrıca değişkenler arasındaki ilişkilerin tespit edilebilmesi amacıyla korelasyon analizi ve aracılık rolünün tespiti için de process macro model 4 uygulanmıştır. Araştırma sonuçlarına göre sağlık çalışanlarının örgütsel adalet algıları ile iş performansları arasında, örgütsel adalet algıları ile paternalist liderlik arasında ve çalışanların iş performansları ile paternalist liderlik algıları arasında istatistiksel olarak anlamlı ve yüksek düzeyde pozitif bir ilişki tespit edilmiştir. Ayrıca çalışanların paternalist liderlik davranışlarının iş performansları üzerindeki etkisinde örgütsel adalet algısının kısmi aracılık rolüne sahip olduğu sonucuna ulaşılmıştır. Sonuç olarak paternalist liderliğin iş performansı üzerindeki dolaylı etkisinde örgütsel adaletin aracılık rolünün olduğu tespit edilmiş olup ilgili değişkenler alan yazını çerçevesinde ayrıca tartışılmıştır.This study was conducted to determine the mediating role of organizational justice perceptions in the relationship between paternalistic leadership behaviors and job performance of healthcare professionals working in a training and research hospital. For the purpose of the study, organizational justice (mediating variable), job performance (dependent variable) and paternalistic leadership (independent variable) scales in the literature were used. The study was conducted by reaching 352 people out of 1387 employees working in a training and research hospital. SPSS 24, AMOS 22 and process macro plug-in were used to analyze the data obtained. In addition, correlation analysis was applied to determine the relationships between variables and process macro model 4 was applied to determine the mediating role. According to the results of the study, a statistically significant and highly positive relationship was found between health care workers' perceptions of organizational justice and their job performance, between their perceptions of organizational justice and paternalistic leadership, and finally between their job performance and their perceptions of paternalistic leadership. In addition, it was found that organizational justice perception has a partial mediating role in the effect of employees' paternalistic leadership behaviors on their job performance. As a result, it was determined that organizational justice has a mediating role in the indirect effect of paternalistic leadership on job performance and the related variables were discussed within the framework of the literature
Physiological Changes Due to Stress of Chromium and Lead in Carthamus tinctorius L.
No full textHeavy metal contamination has become a pressing environmental and public health concern, particularly in developing nations. Chromium (Cr) and lead (Pb) are ubiquitous environmental pollutants that pose substantial threats to ecological integrity and human health, even at sublethal concentrations. This study was conducted to elucidate the effects of Cr and Pb stress on photosynthetic pigments and proline content in Carthamus tinctorius L.cv. Zirkon. The findings revealed that Cr and Pb exposure caused a substantial reduction in chlorophyll a, chlorophyll b, total chlorophyll, total carotenoids, and proline content, while simultaneously increasing the Chl a/b ratio in heavy metal-stressed plants. A comparison of Cr and Pb exposure demonstrated that Cr exposure resulted in more pronounced damage compared to Pb exposure at equivalent concentrations. In response to both heavy metal stress, C. tinctorius L.cv. Zirkon plants displayed an increased accumulation of proline. These findings suggest that Cr and Pb exposure profoundly affects chlorophyll and proline content, leading to physiological alterations in C. tinctorius cv. Zirkon

Afterwards, the existence and uniqueness of fixed points were examined when some appropriate contraction conditions were met for the self mappings defined on this structure. The study consists of four chapters. In the first chapter, a summary of the literature on orthogonal spaces and fixed point theorems is given. In the second section, the preliminaries, definitions and theorems necessary for this study are mentioned. In the third section, we discuss the fixed point theorems and caveats we obtained for the newly defined orthogonal quasi metric spaces and their application to Volterra-integral equations with the help of weak contraction. In the last section we summarize all our results
Effective Atomic Numbers of Glass Samples
No full textEffective atomic numbers are a term used to understand the interaction of a compound or material with radiation. In particular, this term is often used for materials with complex structures that can be expressed by a single fixed atomic number. If different elements in a material are present in different concentrations, the effective atomic number of the material can be calculated by considering the contribution of each element. This is a useful method to better understand the response of the material to radiation or the effect of radiation within the material. In particular, when radiation passes through or acts on the material, the effective atomic number plays an important role in determining factors such as the material's radiation exposure properties, absorption or scattering. Effective atomic numbers are used in radiation interaction analyses in various fields such as materials science, medicine, geophysics and industry. This concept is used to express in a simpler way the radiation properties of compounds in which different elements are combined. In this study, the effective atomic numbers of magnesium borosilicate glasses were investigated. Such studies are important in the field of materials science and glass technology because the chemical constituents of glass and their interactions play a decisive role in the properties of glass. Magnesium borosilicate glasses are often used in industrial applications. The properties of these glasses depend on the amount of elements they contain and their chemical structure. Effective atomic numbers can be used to understand the specific properties of a material. By determining the effective atomic numbers of the elements contained in the glass, this study aims to provide an important basis for understanding the properties of the material, such as radiation exposure, electrical properties or optical properties. © IJCESEN
Investigation of climate change impacts on daily streamflow extremes in Eastern Black Sea Basin, Turkey
No full textThis study was undertaken to evaluate how future uncertain climate-related hydrological responses and low and highflow frequencies affect local hydrology up to the 2100, depending on different Global Circulation Models (GCM) and different Concentration Scenarios (CS). To this end, daily total precipitation and daily mean temperature data were used for RCP4.5 and RCP8.5 CSs by employing GCMs (GFDL-ESM2M, HadGEM2-ES and MPIESM-MR). In the study, the years 1971-2000 were chosen as the baseline period. Future streamflow predictions were modeled by machine learning. The models were calibrated with baseline period data and future streamflow values were predicted by using the best Streamflow Prediction Model during the 2055s (2041-2070) and 2085s (2071-2100) periods. Flow Duration Curves from the streamflow predictions were obtained and by using them, discharges corresponding to 95% probability of exceedance for lowflow and 5% probability of exceedance for highflow were calculated. According to the findings, it is predicted that there will be decrease of approximately 21% in lowflow discharges and approximately 30% in highflow discharges. This prediction has suggested water resources managers to implement mitigation measures to climate change in Eastern Black Sea Basin and most probably in T & uuml;rkiye, especially in the context of continuity of aquatic life and sustainable water supply. It is expected that the paper will take a very important place in estimating and evaluating the expected changes in basin hydrology in the coming years, especially in the highflows and lowflows, which are the key concepts in hydroelectric power generation and in flood management
Çağdaş sanat ve sinema ekseninde dijital yaratıcılığın sınırları üzerine bir araştırma
No full textContemporary art, characterised by blurred boundaries and rule-breaking, now faces a new challenge: Determining the extent to which artificial intelligence should be integrated into its practices. This study examines the impact of AI on creativity in cinema, a contemporary art form, by analysing semi-structured interviews with ten production professionals. Participants were presented with two script treatments - one traditionally written and the other AI assisted - before discussing their impressions. The results indicate that most participants are initially hesitant and have preconceptions about AI in screenwriting. However, despite these reservations, the majority found the AI-assisted treatment to be more successful, albeit for different reasons. This finding suggests the need to reconsider preconceived notions about the role and potential of AI in creative fields.Çağdaş sanat sınırların belirsizleştiği, kuralların yıkıldığı, yeni formların vücut bulduğu bir alan olarak yapay zekayla kurulan ilişkisinde yeni bir mücadele içine girmiştir. Bu, yapay zekanın çağdaş sanatın hangi alanına ne kadar dahil olabileceği ile ilgilidir. Bu bağlamda çalışma kapsamında çağdaş sanatın bir parçası olan sinemada yapay zeka kullanımının yaratıcılık üzerindeki etkisi tartışılmıştır. Üretim alanının içinde olan on profesyonel ile yapılan yarı yapılandırılmış görüşmeler yorumlayıcı analiz yöntemi kullanılarak incelenmiştir. Görüşmeler öncesinde katılımcılara biri senarist tarafından geleneksel yapıda ve yazarın kişisel yazım üslubunu yansıtan, diğeri ise yapay zeka desteğiyle yazılmış iki tretman okutulmuş ve bu metinler üzerine sorular yöneltilmiştir. Araştırma, katılımcıların çoğunun yapay zekanın çağdaş sanata dahil edilmesine mesafeli yaklaştığını ve senaryo yazımında yapay zekanın kullanımına dair önyargılar taşıdığını ortaya koymaktadır. Ancak, önyargılarına rağmen katılımcıların çoğunluğunun yapay zeka destekli tretmanı farklı gerekçelendirmelerle de olsa daha başarılı bulmaları, yapay zekanın yaratıcı süreçlerdeki potansiyeline dair önceden varsayılan algıları sorgulama gerekliliğini işaret etmektedir
The Frequency Dependent of Main Electrical Parameters, Conductivity and Surface States in the Al/ (%0.5 Bi:ZnO)/p-Si/Au (MIS) Structures
No full textThe capacitance/conductance-voltage-frequency (C/G-V-f) features of the Au/p-Si structures with (%0.5 Bi-doped ZnO) interlayer grown by spin-coating technique was investigated between 100 kHz and 1 MHz. The C-2-V curves that depend on frequency were used to determine the electrical-parameters like diffusion-potential (V-D), Fermi-energy level (E-F), barrier-height (Phi(B)), and depletion-layer (W-D) thickness. The value of Phi(B) was found to increase with increasing frequency due to the decrease in surface-states (N-ss) effects on the C-V characteristics. Voltage dependent series-resistance (R-s) was obtained by using Nicollian-Brews method for each frequency and it decreased with increasing frequency. Both the low-high frequency capacitance (C-LF-C-HF) and Hill-Coleman techniques were used to determine the voltage-dependent profile of N-ss. While N-ss decreases with increasing frequency, voltage-dependent on them give two distinctive peaks due to a special distribution of them at interlayer/semiconductor interface in the bandgap depending on their relaxation time. All these experimental results indicate that the existence of R-s, N-ss, and interlayers considerably influence the impedance measurements
