Denizli, Umut
This study examines the ethical implications ofcontemporary digital technologies for human existence, focusing on the semiotic construction of human-machine interaction in the anthology series Black Mirror. The research gap addressed in this article concerns the limited attention paid to the sign systems through which the series produces ethical meanings: while existing studies have discussed BlackMirror mainly as a thematic critique of technological dystopia, fewer have systematically examined how visual and verbal signs organise questions of consciousness, autonomy, surveillance, identity, and responsibility. To address this gap, the study uses a Saussurean and Peircean semiotic framework to analyse how selected episodes encode ethical problems at the intersection of organic and artificial life. The empirical corpus consists of fourteen purposively selected episodes from seasons 2-6, excluding the later seventh season released in 2025, and was examined through qualitative coding of visual and verbal signs related to consciousness transfer, artificial intelligence (AI), social media, virtual reality, surveillance, and digital vigilantism. The analysis identifies recurring oppositions between embodiment and disembodiment, autonomy and control, presence and mediation, and responsibility and outsourcing, which together articulate specific moral narratives about technological progress. The articles' original contribution lies in linking semiotic form to technological ethics: it shows how popular techno-dystopian fiction not only represents ethical problems thematically but also constructs them through recurring signs, oppositions, motifs, and narrative patterns. The findings suggest that Black Mirror foregrounds the fragility of human agency in technologically mediated environments and problematises unregulated innovation as a threat to dignity, privacy, and social cohesion within the selected corpus. The study concludes that these findings are interpretive insights from a purposively selected corpus, while also indicating the need for further research on how AI and related technologies are represented, governed, and ethically implemented in ways that protect human agency, dignity, and the broader public interest.

Cosar, Dilan Aktepe; Demirag, Hatice; Cin, Aynur
Background: Chronic illnesses are long-term, noncommunicable diseases that significantly affect daily life. In addition to physical symptoms, they can reduce quality of life by causing psychological effects such as anxiety and depression. Patients often seek health information to better manage their condition. Methods: This study aimed to examine the level of health information-seeking behavior among individuals with chronic diseases and the factors influencing this behavior. The sample group for this descriptive study consisted of 306 individuals with chronic illnesses who visited X Hospital in northeastern T & uuml;rkiye between April 1, 2024, and February 1, 2025. All individuals completed a questionnaire consisting of the Patient Information Form and the Health Seeking Behavior Scale. Results: The sociodemographic characteristics of patients with chronic diseases, such as education level, marital status, and chronic disease duration, significantly affected the health-seeking behavior scores. According to the research findings, the highest mean score was determined as 12.30 +/- 2.62 in the occupational health-seeking subdimension, whereas the lowest mean score was determined as 8.78 +/- 3.83 (min-max: 3-15) in the traditional health-seeking subdimension. The total mean score of the Health Seeking Behavior Scale was 32.2 7 +/- 7.73. Conclusions: Individuals with chronic illnesses tend to prefer professional health care services when seeking health-related behaviors. Health-seeking behaviors were higher among high school graduates, single individuals, and those without chronic illnesses.

Öztürk, Umit; Yalçin, Seda
It is possible to say that Plato's texts are heavily intertwined with mythological elements or narratives. One of the main reasons for this fact can be found that the characters in the dialogues are constructed in a way that vividly conveys the spirit of the period. However, some terms or concepts that were present in the cultural atmosphere of the period and in the vocabulary of every philosopher writing at that time make the understanding of the texts extremely difficult, especially when the metaphorical contexts are taken into account. Among such concepts, there are daimonion and daim & omacr;n and their grammatical derivatives, which are extremely difficult to translate into different languages. Moreover, when the last-mentioned concepts are being connected with the terms such as theos and its derivatives, which altogether can be considered to be in the same semantic family, it becomes even more difficult to understand some Platonic texts. This article primarily aims to analytically distinguish between the daimonion and daim & omacr;n narratives in the Apology and the Symposium. Secondly, via referring to other Platonic texts, the question of whether these concepts can be understood on common ground is discussed.
- MakaleAçık Erişim2026The Role of Social Media Usage in the Professional Development of Employees in Micro-Scale Furniture Manufacturing Enterprises in Trabzon, Turkey
Top, Yener; Sönmez, Gulen
Micro-scale enterprises contribute to the economies of the countries they are located in, such as employment generation, rural development, and providing training opportunities for semi-skilled workers. They constitute the majority of enterprises in terms of number, but their share in the production rate is low. Furniture manufacturing is one of the sub-branches of the main manufacturing industry, and the majority of the enterprises that produce furniture are micro-scale. These enterprises face several challenges. One of these challenges is that a significant portion of their employees have not received any formal vocational training. The communication opportunities and tools (such as social media) of our time have made it easier to access information. This has made informal education possible for those who have not received a formal vocational training or have received it but want to improve themselves. In this study, the use of social media in the vocational development of employees of micro-scale enterprises manufacturing furniture was investigated. With this objective, a structured survey was conducted face-to-face with 110 participants in the central district of Trabzon to adequately represent the target population. To analyze the data, frequency tables, Spearman Correlation Analysis, Kolmogorov-Smirnov Normality, Kruskal-Wallis, Mann-Whitney U and Chi-Squared Tests were used. The findings indicate that a significant majority of the employees are aged between 25 and 54, with 47.2 % lacking any vocational training. Furthermore, substantial differences were observed in the employees' use of social media for vocational development purposes, correlated with their age and educational level.

Çalik, Erdogan Serdar
This article examines Augustine's understanding of knowledge not merely as a theoretical acquisition but as a moral process that transforms the human being. The first section of the study addresses the foundations of Augustine's epistemology, discussing the connection between knowledge, happiness, and wisdom, as well as the ethical dimension of knowledge and its role in the transformation of the soul. Furthermore, the epistemological role of memory and time is evaluated as dynamics that enable the pursuit of truth. The second section analyzes the influence of Augustinian epistemology during the scholastic period. In this context, Anselm's faith-based approach, Bonaventure's mystical interpretation, and Thomas Aquinas' Aristotelian synthesis are examined, with a focus on the nominalist critiques beginning with William of Ockham. The conclusion states that Augustine's epistemology presents a unique and enduring model that grounds the source of knowledge in inner enlightenment and its purpose in virtuous living, thus concluding the study.

Demir, Habip
Purpose: This study aims to examine how the official ideological discourse in Iran is produced through the educational curriculum and how Sunni Islam is positioned within this institutional discourse. In this context, our study examines how Sunni Islam is represented in the Ma`& amacr;rif-i Isl & amacr;m & imacr;: V & imacr;je-yi Ahl al-Sunnat textbooks prepared for Sunni students at the primary education level in Iran, and through which discursive strategies this representation is constructed. Considering the determining influence of Twelver Shi'ism- the official sect of the Islamic Republic of Iran-on state institutions and the educational system, the way Sunnism is defined in institutional texts emerges as a significant subject of scholarly inquiry. In this context, the study seeks to demonstrate that sectarian identities are produced not only through doctrinal differences but also through institutional discourse and educational materials. The central research problem of the study is to identify the concepts, historical references, and narratives through which the Sunni sect is represented within Iran's official educational system. Method: The study was designed within the framework of a qualitative research approach. The data source for the study consists of the elective textbooks titled Ma`& amacr;rif-i Isl & amacr;m & imacr;: V & imacr;jeyi Ahl al-Sunnat prepared for Sunni students by the Iranian Ministry of Education as a supplement to the mandatory textbooks for elementary school (grades 2-6) and middle school (grades 7-9). A total of 8 textbooks were subjected to document analysis in this study; the books were examined holistically, and the texts, activities, and visual narratives were evaluated thematically using a discourse analysis approach. Findings: The findings reveal that Sunni identity in the examined textbooks is represented through several recurring thematic frameworks. In sections related to ritual practices, the practices of Sunni legal schools are explained in detail, enabling Sunni students to learn the religious practices associated with their own tradition. At the same time, the selection of historical figures largely avoids controversial personalities that could potentially generate sectarian tensions; instead, the textbooks highlight companions and scholars who are respected to some extent in both Sunni and Shi'i traditions. Furthermore, narratives concerning the Ahl al-Bayt and the event of Karbala are presented both as shared religious references and as significant elements of Shi'i historical discourse. The treatment of concepts such as taqlid, mujtahid, and religious leadership also indicates that these textbooks function not merely as pedagogical materials but as texts that carry ideological meanings associated with the political and ideological discourse of the Iranian state. Conclusion: The study concludes that the textbooks prepared for Sunni students in Iran constitute important institutional texts that demonstrate how sectarian identity is represented at the institutional level. Within these texts, Sunni identity is recognized and made visible to a certain extent; however, it is simultaneously redefined within a discursive framework compatible with the official Shi'i ideological structure. In this regard, the research contributes to the literature in the field of History of Islamic Sects by demonstrating how sectarian identities are produced and represented through educational materials. Moreover, the findings contribute to contemporary discussions on the relationship between sectarian identity and education, while also indicating new directions for future research on similar institutional texts.

Köse, Asli
Employing the systematic review methodology, this study aims to address how digital health literacy and e-health literacy influence people's quality of life. This systematic review includes studies that examined the effect of e-health literacy and digital health literacy on quality of life. The results of 12 research papers meeting the standards established within the parameters of this study were divided into two groups: ehealth literacy and digital health literacy. The effect of e-health literacy on quality of life was assessed in five of the thirteen studies, whereas that of digital health literacy on quality of life was assessed in eight of them. The study sample consisted of people with cancer, people with long-term conditions like asthma, people who were following their postoperative treatment regimens, people affected by the COVID-19 epidemic, the elderly, women, children, and students. Only one study reported that e-health literacy had a negative influence on quality of life, whereas 11 studies emphasized that digital health and e-health literacy had a positive influence. Policies are required to facilitate the use and access to digital health technology by various societal groups, including patients, the elderly, women with unequal social status, children, and learners.

Aksut, Yavuz Selim; Yetgín, Sukru
In this study, ground blast furnace slag (GBFS) and waste volcanic rock dust (RD) produced in a natural stone processing plant were used as binders. The binders were activated with Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) to produce two types of concrete: alkali-activated concrete without fibers (AAC) and alkali-activated concrete with fibers (FAAC). In the production of concrete, steel and polyester fibers were used separately and hybrid at 0.25%, 0.50%, 0.75% and 1.0% by volume and a total of 117 15x15x15 cm cube specimens were produced. The mechanical properties of the specimens were evaluated by concrete surface hardness, ultrasonic pulse velocity and concrete compressive strength tests at 3, 7 and 28 days. The results obtained using non-destructive test methods were matched with concrete compressive strength values using various empirical formulas. Calculated concrete compressive strength values and actual concrete compressive strength values were compared using data analysis method. As a result, it was observed that there was a very significant correlation between the experimental compressive strength and the combined method in which 7-day surface hardness and ultrasound transmission rate were used together to calculate the compressive strength.

Üzülmez, Mehmet
This study evaluates land use patterns in reclaimed coastal areas of Ortahisar district, Trabzon, from 2000 to 2024. It examines the role, functions, and environmental and structural impacts of reclamation in urban development. In mountainous cities like Trabzon, with limited flat land, sea filling is a key urban expansion strategy. The research combines literature review, satellite image analysis, and GIS mapping (ArcGIS), supported by climate, population, and topographic data from official sources. The study analyses reclaimed zones including Akyaz & imath;, Be & scedil;irli, Ganita, and De & gbreve;irmendere. InAkyaz & imath;, 39 hectares serve the & Scedil;enol G & uuml;ne & scedil;Sports Complex, and 29 hectares serve the city hospital ,which is currently under construction, alongside a mosque, fishermen's shelter, and parking. Ganita includes 17 hectares of parks and recreation and 9 hectares for transport infrastructure, reflecting a public-use planning approach. De & gbreve;irmendere hosts parks, fishermen's shelters, roads, a port, and breakwaters, with about 28 hectares unused. These areas address population growth and land scarcity, creating new urban spaces but posing environmental and engineering risks. International studies highlight issues such as ground settlement, structural instability, flood and storm vulnerability, and marine ecosystem damage in reclaimed lands. While valuable for infrastructure and public services, reclamation should be managed beyond spatial growth. The study stresses how multifunctional, public-focused, strategic planning shaped these areas. However, comprehensive interdisciplinary approaches are needed for ground safety, sustainability, and ecosystem protection. Future planning must mandate geotechnical surveys and environmental impact assessments. Reclamation should align with natural processes, not just physical expansion. Public participation and integrating local needs are crucial. Transport and access plans should balance coastal access and sustainability. Ortahisar's reclamations offer short-term urban solutions, but long-term risk reduction requires integrated sustainable planning.

Kaya, Asli Uner
The nature and function of thought experiments, which have become an important part of philosophical and scientific discourse, are among the topics that have been researched with great interest not only by philosophers but also by historians of science, cognitive scientists and psychologists in recent years. Thought experiments, which we can trace back to the Pre-Socratics, are frequently encountered in the Middle Ages, especially in fields such as theology and natural philosophy. Imaginary scenarios designed by important figures in the Islamic world such as Ibn Sina, Ibn al-Haytham and Ghazali provide important information about the way thought experiments were used in the period. Ibn Sina was the first philosopher to try to explain the psychological basis of thought experiments. The fundamental question he focuses on is: What is the source of the premises used in thought experiments? According to Ibn Sina, the source of thought experiments is wahm, an internal, sensory faculty that has no exact English equivalent but is usually translated as estimative faculty. My aim in this article is to focus on the faculty of illusion that Ibn Sina introduced while creating the psychological infrastructure of thought experiments and to reveal the role that this faculty plays in the formation of thought experiments.
- MakaleYalnız künye2026The lived experience of individual stock investors during decision-making: a phenomenological perspective on investment psychology
Soydas, Safak Sonmez
Purpose - This study explores how individual stock investors experience and interpret their decision-making processes beyond cognitive bias frameworks. It aims to reveal how investment decisions are shaped through cultural memory, moral values, social identity and digital environments, emphasizing the lived meanings investors attribute to risk, gain, and loss. Design/methodology/approach - A qualitative phenomenological design was employed. In-depth semi-structured interviews were conducted with 20 active individual stock investors in T & uuml;rkiye. Data were analyzed using Colaizzi's seven-step phenomenological method to identify the lived meaning structures underlying investment decision experiences. Findings - Investment decisions emerged as multidimensional experiences organized around four interrelated domains: cultural roots and collective economic memory, moral and religious tensions, social status and identity construction, and digitalization with emerging economic perceptions. Participants interpreted risk, gain, and investment outcomes through family narratives, moral and religious evaluations, identity-related concerns, and digitally mediated information environments rather than solely through rational calculations. Research limitations/implications - The findings are based on a limited qualitative sample and therefore cannot be statistically generalized. However, they contribute to a deeper theoretical understanding of investment behaviour by integrating cultural, moral, identity-related, and digital dimensions within a phenomenological behavioural finance perspective. Future research may build on these findings through mixed-method designs and cross-cultural comparisons. Practical implications - The findings support investor education programmes, decision-support systems and behavioural policy design by highlighting the experiential and meaning-based dimensions of investment decision-making. Social implications - The study demonstrates that investment decision-making is shaped by cultural values, moral interpretations, social identity processes and digitally mediated environments, suggesting that financial decisions are socially embedded rather than purely individual or rational. These findings may contribute to more socially sensitive financial literacy initiatives and policy development. Originality/value - This study extends behavioural finance by introducing a phenomenological lived-experience perspective, demonstrating that investment decision-making emerges through interacting cultural, moral, identity-related and digital meaning structures rather than solely through cognitive biases.

Gül, Ismail; Koç, Ozcan; Arslan, Adem
Healthcare management students undergo an educational process aimed at acquiring various knowledge and skills to achieve professional competence. Self-discipline and ethical values play a crucial role in both academic success and professional development during this process. Self-discipline contributes to students' timely and effective completion of their duties, while ethical values enhance individuals' ability to distin-guish right from wrong and to act in accordance with social norms. This study examined the relationship between the ethical value perceptions and self-discipline levels of G & uuml;m & uuml;shane University Health Management students. Quantitative methods were used in the study and data were collected via a survey. The data obtained were analyzed using t-tests, ANOVA, and correlation analysis. The analysis results revealed a significant relationship between students' ethical value perceptions and self-discipline levels. These findings demonstrate that ethical values and self-discipline are not inde-pendent concepts; rather, they are interconnected, complementary, and reinforcing. The research is expected to contribute to the development of educational programs in the field of healthcare management and to guide practices aimed at increasing students' ethical and self-discipline levels.

Barley grain is rich in nutritional value and mineral elements. It is an important cereal crop used human food, malt and feed for animals. This study was conducted to determine some physical and chemical quality characteristics, like thousand-grain and hectoliter weight, protein, moisture, ash, starch, oil, ADF (acid detergent fiber), NDF (neutral detergent fiber) percent, potassium (K), magnesium (Mg), and phosphorus (P) contents of 14 two-rowed barley cultivars (Akar, Burakbey, Tarm-92, Aydanhan & imath;m, Zeynelaga, Keser, Balkan-96, Hilal, Sur 93,Sahin 91, Cumra-2001, Erciyes, Efes-98, Anadolu 98) with a randomized complete block design and three replications for two years during the 2016-2018 growing seasons (wintery) in the terrestrial climate conditions ofSiran-Gumu & scedil;hane (Turkiye) located in the Eastern Black Sea Region. According to the two-year mean results, the thousand-grain weight of the cultivars ranged between 35.74-46.27 g, hectoliter weight 62.03-68.18 kg hl(-1,) protein percent 10.20-14.08%, moisture percent 09.32-09.75%, ash percent 1.99-2.21%, starch percent 57.22-61.77%, oil percent 1.52-2.02%, ADF percent 5.72-7.82%, NDF percent 21.19-23.20%, K content 0.657-0.742%, Mg content 0.156-0.191% and P content 0.401-0.430%. A positive and significant correlation was determined between thousand-grain weight and hectoliter weight, starch, oil, ADF, NDF, K, Mg, and P percent. Aydanhan & imath;m, Cumra-2001, Akar, Efes-98 and Balkan-96 cultivars were the prominent cultivars in terms of Physical and chemical quality characteristics and mineral substance values were evaluated in the study. Therefore, it is seen that these cultivars can be recommended to farmers who grow forage barley in the region.

Ekizoglu, Ozlem; Tetik, Sibel; Zambak, Omer; Temur, Canan Sayin; Can, Yusuf; Isik, Utku; Koc, Mustafa Can
Background/objective Psychological well-being disorders are increasingly prevalent among young people. While physical activity is known to benefit psychological well-being, the mechanisms-particularly the role of physical self-perception and gender in recreational context remain underexplored. Grounded in the Conservation of Resources (COR) Theory, this study investigates the mediating role of physical self-perception in the relationship between recreational physical activity and psychological well-being and examines whether gender moderates this mediation among youth aged 15-24.Methods A descriptive-relational survey design was employed. The sample comprised 468 young adults (58.5% male, 41.5% female; M_age = 20.08) who regularly participated in recreational physical activities. Data were collected using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Self-Perception Profile (PSPP), and the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Mediation and moderation analyses were conducted using PROCESS macro-Models 4 and 7.Results The direct effect of physical activity on psychological well-being was not significant. However, physical self-perception fully mediated the relationship between physical activity and psychological well-being (indirect effect: beta = 0.219, 95% CI [0.151, 0.290]). Among the sub-dimensions of physical self-perception, body attractiveness had the strongest mediating effect. Moderation analysis revealed that gender did not significantly moderate the mediation pathways (a path: p = 0.156; b path: p = 0.954). The mediation mechanism operated with similar strength in both males and females.Conclusion Recreational physical activity improves psychological well-being entirely through the enhancement of physical self-perception, supporting the COR theory that physical activity acts as a resource investment. This mechanism is universal across genders in recreational settings. Interventions aiming to improve youth psychological well-being should not only promote physical activity but specifically focus on fostering positive physical self-perception and body image in inclusive, non-judgmental environments.

In this study, the excitation functions of the 67Zn(p,n)67Ga, 68Zn(p,2n)67Ga, and 89Y(p,n)89Zr reactions were investigated. Nuclear reaction simulations were performed using the TALYS 1.95 and EMPIRE 3.2 codes, by using Two Component Exciton Model, Geometry Dependent Hybrid Model, Exciton Model, and Hybrid Monte Carlo Simulation. In parallel, a feedforward artificial neural network (ANN) trained with the Levenberg-Marquardt (LM) algorithm was employed to predict the same reaction cross-sections using experimental data. Comparative analysis revealed a strong consistency between TALYS and EMPIRE calculations, ANN predictions, and experimental results, with the ANN providing enhanced predictive performance in energy regions where experimental data are sparse or uncertain. Furthermore, activation and yield calculations confirmed the feasibility of producing clinically relevant quantities of 67Ga and 89Zr under realistic irradiation conditions. In conclusion, the use of physics-based nuclear reaction codes with data-driven ANN models has been demonstrated to be useful in medical radionuclide production studies by providing a complementary framework for cross-section estimation.

Boyaci, Faruk; Sahin, Mustafa Kursat; Akcay, Murat; Yanik, Ahmet; Yenercag, Mustafa; Seker, Onur Osman; Ucar, Melisa; Kokcu, Halil Ibrahim; Ozturk, Berkant; Kaya, Enes
Background Existing CHA(2)DS(2)-VASc-based scores incompletely capture the prognostic impact of chronic obstructive pulmonary disease (COPD) and of graded renal dysfunction in patients undergoing transcatheter aortic valve implantation (TAVI). We acknowledge that the score's development in a high-risk, high-comorbidity cohort may produce optimistic performance estimates that require attenuation through external validation. We aimed to develop a novel COPD-augmented R(2)CHA(2)DS(2)-VA (COPD-R(2)CHA(2)DS(2)-VA) score that systematically integrates quantitative renal function and COPD, and to internally assess its discriminative performance for one-year all-cause mortality and major adverse cardiovascular events (MACE). Methods In this single-center, retrospective cohort study, 622 consecutive patients undergoing TAVI for severe aortic stenosis (2018-2024) were analyzed. The COPD-R(2)CHA(2)DS(2)-VA score was constructed as a prespecified clinical tool by augmenting the R(2)CHA(2)DS(2)-VA framework with COPD (1 point) and refining renal dysfunction into two graded estimated glomerular filtration rate strata (eGFR 30-59 mL/min/1.73 m & sup2;: 1 point; eGFR < 30: 2 points). Discriminative performance was evaluated using receiver operating characteristic curve analysis with bootstrap internal validation (2,000 resamples) and compared with established CHA(2)DS(2)-VASc-based scores. Multivariable logistic regression assessed the independent prognostic value of the score treated as a continuous variable. Results The COPD-R(2)CHA(2)DS(2)-VA score demonstrated encouraging discriminative ability for one-year all-cause mortality (apparent area under the curve [AUC] 0.946, 95% CI 0.926-0.971). As a prespecified tool with fixed component weights, bootstrap internal validation confirmed negligible optimism (mean optimism - 0.00014), with bias-corrected AUC identical to the apparent value. The addition of COPD significantly improved mortality discrimination over the R(2)CHA(2)DS(2)-VA score (Delta AUC + 0.033, p = 0.0001). For one-year MACE, the apparent AUC was 0.806 (95% CI 0.765-0.852); the addition of COPD did not significantly enhance MACE discrimination (Delta AUC + 0.001, p = 0.853). In multivariable analysis, each one-point increase in the COPD-R(2)CHA(2)DS(2)-VA score was independently associated with 3.52-fold higher odds of one-year mortality (95% CI 2.45-5.06, p < 0.001) and 2.02-fold higher odds of MACE (95% CI 1.67-2.46, p < 0.001). The bias-corrected AUC of the full multivariable model was 0.973 (95% CI 0.962-0.984) for mortality and 0.795 (95% CI 0.752-0.841) for MACE. Conclusions The COPD-R(2)CHA(2)DS(2)-VA score demonstrated encouraging discriminative ability for one-year all-cause mortality after TAVI in this single-center development cohort (apparent AUC 0.946). However, this high discriminative performance is likely influenced by the elevated comorbidity burden in our cohort and the single-center design, and should be interpreted as an upper-bound estimate. The addition of COPD provides a statistically significant but clinically modest incremental improvement for mortality (Delta AUC + 0.033, p = 0.0001), with no significant enhancement for MACE (Delta AUC + 0.001, p = 0.853). These findings are preliminary and hypothesis-generating; urgent external validation in diverse, prospective cohorts is essential before any clinical application can be considered. At present, this score should be regarded as a development-phase, hypothesis-generating tool that complements rather than replaces guideline-recommended instruments such as STS-PROM and EuroSCORE II. The score's clinical utility remains unproven.

Pala, Fahrettin; Barut, Abdulkadir; Torusdag, Mustafa; Pilatin, Abdulmuttalip; Henni, Mohamed Djafar
In developing economies, rapid economic growth intensifies environmental pressures, thereby increasing the importance of financial inclusion, energy intensity, and natural resource dependence for environmental sustainability. This situation necessitates a holistic examination of the determinants of environmental degradation in emerging markets, which motivates this study. In this context, the study examines the effects of financial inclusion, energy intensity, and natural resource rents on carbon dioxide (CO2) emissions in BRICS and MINT countries and empirically tests the validity of the Environmental Kuznets Curve (EKC) hypothesis. Accordingly, annual panel data covering the period 2000-2020 are analysed using a machine learning (ML)-based estimation framework, the Augmented Mean Group (AMG) estimator, and Panel Quantile Regression (PQR). The findings indicate that natural resource rents increase CO2 emissions in BRICS, whereas they reduce emissions in MINT. Moreover, energy intensity and income per capita are found to increase CO2 emissions across all quantiles in both country groups. The environmental impact of financial inclusion is heterogeneous, reducing CO2 emissions in BRICS countries while increasing emissions in MINT countries. These results underscore the critical importance of explicitly incorporating country-specific heterogeneity into environmental sustainability policy design.

Amino acid leaching has been considered an environmentally friendly alternative for gold recovery; however, the dissolution of mercury (Hg) during the leaching of amalgamation tailings remains a major challenge. This study is a novelty study that focuses on Hg removal by passing the Hg-containing tailings, previously processed by amalgamation, into solution via glycine (NH(2)CH2COOH) leaching. In this regard, a precipitation method using sodium sulfide (Na2S) was developed to remove Hg from solutions obtained after glycine leaching. The effects of precipitation time, pH, Na2S dosage, and temperature were investigated. The effects of pH, precipitation time, and temperature were found to be limited within the investigated ranges. The results showed that Na2S dosage was the most effective parameter in mercury removal. The initial Hg concentration of 12,160 ppb was reduced to 223 ppb at a Na2S:Hg molar ratio of 60, corresponding to approximately 98% removal efficiency under the selected operating conditions. Increasing the Na2S:Hg ratio to 80 resulted in a slightly higher removal efficiency (similar to 99%) with a final Hg concentration of 144 ppb; however, a ratio of 60 was considered optimal in terms of reagent consumption and process efficiency. The outcomes indicate that Hg removal with Na2S is a rapid and effective process under alkaline conditions, while Au remains in solution and Cu and Ag are partially removed, indicating limited selectivity and the need for further optimization. Therefore, this study provides a basis for developing more environmentally friendly processes for amalgamation tailings.

The study sheds light on the subtle interactions among financial development, foreign direct investment (FDI), and the quality of regulatory frameworks, with particular reference to their deep influence on renewable energy use and carbon emissions across 22 developed countries from 2002-2021. The results show an interesting tendency: Financial development and FDI will reduce reliance on renewable energy, whereas a significant increase in GDP per capita will increase reliance. Secondly, carbon emissions have a negative association with the adoption of renewable energy and financial development, though both reduce environmental quality; there is a positive relation between real gross domestic product (GDP) and energy depletion in terms of these toxic emissions. The significant role of regulatory quality as a moderator in this process is particularly striking. There is a direct correlation between financial stability and more robust regulation, resulting in reduced financial liquidity available for investing in renewable projects and restricting the free flow of clean FDI. Crucially, the paper argues that when combined with strong regulation, FDI is more likely to contribute to reductions in emissions, while FYGD, nevertheless regulated at a high level of quality, should raise emissions. Winding up, the result indicates that neither financial depth nor institutional quality, in isolation, is sufficient to deliver significant environmental improvement. Thus, it is urgent to adopt sound green finance policies and to formulate focused regulatory systems that integrate financial development and foreign direct investment with a broader sustainability agenda.
