Decarbonizing the transportation sector is critical for sustainable development, particularly in rapidly urbanizing countries like Turkiye. This study analyzes fuel demand elasticities for diesel, gasoline, and LPG across 12 NUTS-1 regions of Turkiye in 2022, using a panel random effects SUR approach. The model accounts for regional variation and fuel interactions, producing robust estimates that uncover significant spatial and temporal differences in consumption patterns. Uniquely, diesel demand displays a significantly positive price elasticity, challenging the conventional assumption of inelasticity. Gasoline demand is moderately price-sensitive, while LPG appears relatively unresponsive. Strong cross-price elasticities—especially between diesel and gasoline—point to substitution effects that can inform more adaptive policy frameworks. Seasonal fluctuations and Istanbul’s outsized impact also shape national trends. These findings underscore the need for differentiated region- and fuel-specific strategies. While higher gasoline taxes may effectively reduce demand, lowering diesel and LPG use will require complementary measures such as infrastructure upgrades, behavioral incentives, and accelerated adoption of alternative fuels. The study advocates for regionally adjusted carbon pricing, removal of implicit subsidies, and targeted support for electric and hybrid vehicles. Aligning fiscal tools with actual demand behavior can enhance both the efficiency and equity of the transition to a low-carbon transportation system. Full article

This study investigates the dynamic interdependencies among key sectors of Borsa Istanbul—industrial, services, technology, banking, and electricity—using a novel network-geometric framework. Daily closure prices from 2022 to 2024 are transformed into logarithmic returns and analyzed via a sliding window approach. In each window, mutual information is computed to construct weighted networks that are filtered using Triangulated Maximally Filtered Graphs (TMFG) to isolate the most significant links. Forman–Ricci curvature is then calculated at the node level, and entropy measures over k-neighborhoods ($k=1,2,3$) capture the complexity of both local and global network structures. Cross-correlation, Granger causality, and transfer entropy analyses reveal that sector responses to macroeconomic shocks—such as inflation surges, interest rate hikes, and currency depreciation—vary considerably. The services sector emerges as a critical intermediary, transmitting shocks between the banking and both the industrial and technology sectors, while the electricity sector displays robust, stable interconnections. These findings demonstrate that curvature-based metrics capture nuanced network characteristics beyond traditional measures. Future work could incorporate high-frequency data to capture finer interactions and empirically compare curvature metrics with conventional indicators. Full article

The influence of mobility modes within Positive Energy Districts (PEDs) has gained limited attention, despite their crucial role in reducing energy consumption and greenhouse gas emissions. Buildings in the European Union (EU) account for 40% of energy consumption and 36% of greenhouse gas emissions. In comparison, transport contributes 28% of energy use and 25% of emissions, with road transport responsible for 72% of these emissions. This study aims to design and optimize a synthetic PED in Istanbul that integrates renewable energy sources and public mobility systems to address these challenges. The renewable energy sources integrated into the synthetic PED model include solar energy, hydrogen energy, and regenerative braking energy from a tram system. Solar panels provided a substantial portion of the energy, while hydrogen energy contributed to additional electricity generation. Regenerative braking energy from the tram system was also utilized to further optimize energy production within the district. This system powers a middle school, 10 houses, a supermarket, and the tram itself. Optimization techniques, including Linear Programming (LP) for economic purposes and the Weighted Sum Method (WSM) for environmental goals, were applied to balance cost and CO₂ emissions. The LP method identified that the PED model can achieve cost competitiveness with conventional energy grids when hydrogen costs are below $93.16/MWh. Meanwhile, the WSM approach demonstrated that achieving a minimal CO₂ emission level of 5.74 tons requires hydrogen costs to be $32.55/MWh or lower. Compared to a conventional grid producing 97 tons of CO₂ annually, the PED model achieved reductions of up to 91.26 tons. This study contributes to the ongoing discourse on sustainable urban energy systems by addressing key research gaps related to the integration of mobility modes within PEDs and offering insights into the optimization of renewable energy sources for reducing emissions and energy consumption.

This paper focuses on campaigns against the Council of Europe Convention on preventing and combating violence against women and domestic violence (Istanbul Convention). These campaigns not only obstructed ratification processes in a number of countries, but also that the openly hostile and highly gendered attacks had a direct impact on women’s rights activists and their work, seriously hindering their work, but also affecting their well-being and safety. In this paper we explore the violent implications of the campaigns against the Istanbul Convention which are part of wider anti-gender campaigns. We argue that the violence of the campaigns and the violent implications should be considered gendered political violence, which effectively marginalizes women and other targeted groups and obstructs their participation in society and politics and as such is central to current autocratization tendencies and undermining of democracy.

In response to technological advances, environmental concerns, and the depletion of conventional energy sources, the world is increasingly focusing on renewable energy sources (RES) as a means of generating electricity in a more sustainable and environmentally friendly manner. Türkiye, with its advantageous geographical location, long hours of sunshine, and favourable climatic conditions, has a high potential for the use of solar energy. The objective of this study was to identify an energy system that minimizes investment costs while optimizing the levelized cost of energy (LCOE) and minimizing greenhouse-gas (GHG) and carbon dioxide emissions. To achieve this, the study used the concept of nanogrids (NGs) and carried out different evaluations for electric vehicle charging stations (EVCS) at different energy levels connected to the grid. The research focused on classic apartment buildings and multistory condominium-style buildings in Istanbul, Türkiye. Using HOMER Grid 1.11.1 version software, the study identified two optimal configurations: a PV–GRID system with 7 kW photovoltaic capacity and a PV–WT–GRID system with 90 kW PV capacity and 6 kW wind-turbine capacity. These configurations had a significantly lower LCOE compared to the cost of electricity from the conventional grid. When examining the sensitivity to economic factors, it was observed that the net present cost (NPC) and LCOE values fluctuated with electricity prices, inflation rates, and equipment costs. In particular, the two optimal configurations did not include a battery energy-storage system (BESS) due to the low energy demand in the PV–GRID system and the efficiency of the wind turbines in the PV–WT–GRID system. This highlights the need to tailor energy solutions to specific consumption patterns and resource types. In conclusion, the adoption of PV–GRID and PV–WT–GRID systems in Istanbul’s urban buildings demonstrates economic viability and environmental benefits, highlighting the importance of renewable energy sources, particularly solar PV, in mitigating energy-related environmental challenges, such as reducing CO₂ emissions and reducing dependence on conventional grid electricity.

This paper presents and critically interrogates a comprehensive 7Ps framework for analysing and addressing gender-based violence. It takes the UN and the Council of Europe’s models as points of departure and develops the framework beyond the current state of the art, explains its different components, and offers reflections on its use in the practice of gender-based violence research. The UN 3P model, encompassing prevention, protection, and prosecution, later developed by the Council of Europe’s Istanbul Convention into a 4P model, comprising prevention, protection, prosecution, and integrated policies, has since been revisited, elaborated upon, and expanded in work focusing on gender-based violence in particular domains, such as female genital mutilation or gender-based violence in sport. To study gender-based violence in academia, the comprehensive 7Ps analytical framework has been deployed to interrogate the policies in place at national and institutional levels, including sexual harassment. Based on empirical data and conceptual analysis in the EU project UniSAFE: Gender-based violence and institutional responses: Building a knowledge base and operational tools to make universities and research organisations safe (2021–2024), the paper argues that the refined 7Ps model, comprising Prevalence, Prevention, Protection, Prosecution of offenders (and disciplinary measures), Provision of services, Partnerships between actors, and Policies specifically addressing the issue, allows for a more encompassing approach, in turn allowing a more fine-grained understanding of variations and explanations for success (or lack thereof) in terms of outcomes.

Background: Currently, medications and behavioral modifications have limited success in the treatment of functional constipation (FC). An individualized diet based on microbiome analysis may improve symptoms in FC. In the present study, we aimed to investigate the impacts of microbiome modulation on chronic constipation. Methods: Between December 2020–December 2021, 50 patients fulfilling the Rome IV criteria for functional constipation were randomized into two groups. The control group received sodium picosulfate plus conventional treatments (i.e., laxatives, enemas, increased fiber, and fluid intake). The study group underwent microbiome analysis and received an individualized diet with the assistance of a soft computing system (Enbiosis Biotechnology^®, Sariyer, Istanbul). Differences in patient assessment constipation–quality of life (PAC-QoL) scores and complete bowel movements per week (CBMpW) were compared between groups after 6-weeks of intervention. Results: The mean age of the overall cohort (n = 45) was 31.5 ± 10.2 years, with 88.9% female predominance. The customized diet developed for subjects in the study arm resulted in a 2.5-fold increase in CBMpW after 6-weeks (1.7 vs. 4.3). The proportion of the study group patients with CBMpW > 3 was 83% at the end of the study, and the satisfaction score was increased 4-fold from the baseline (3.1 to 10.7 points). More than 50% improvement in PAC-QoL scores was observed in 88% of the study cohort compared to 40% in the control group (p = 0.001). Conclusion: The AI-assisted customized diet based on individual microbiome analysis performed significantly better compared to conventional therapy based on patient-reported outcomes in the treatment of functional constipation.

Since sustainability has become a major concern in the construction industry, making economically efficient investment decisions in energy conservation are needed to minimize energy consumption for space heating and cooling. Although Air-Source Heat Pump (ASHP) systems are used to meet buildings’ heating and cooling demands worldwide, high initial setup costs limit the widespread use of these systems. This paper presents comparative assessment of ASHP system versus conventional gas-fired boiler system for a real commercial building with a floor area of 2500 m² in Istanbul, Turkey. The key performance variable, Coefficient of Performance (COP), of the ASHP system was experimentally evaluated. The experimental results revealed that the system’s COP ranged from 3.22 to 4.32, while the outside temperature ranged from 4.8 to 18.6 °C and the supply water temperature ranged from 32.2 to 36.2 °C. Moreover, the economic analysis results showed that despite the high initial cost, ASHP systems are cost competitive against gas-fired boiler in Turkey. ASHP system could reduce the present value of total Life-Cycle Cost (LCC) by up to 26.4% (47,865 USD) compared to the conventional gas-fired boiler system because it can dramatically reduce the energy consumption per year Full article

This article examines young Muslim women’s dissident mentalities, practices, and subjectivities that confront the epistemological conditions whereby right-wing populist (RWP) gender politics operates in Turkey. Relying on frame theory in social movement research and the Foucauldian approach to resistance, dissent, and protest, it explores Muslim feminist critique of RWP gender discourse mainly with a focus on the following issues: (i.) Instrumentalization of the headscarf, (ii.) familialist policies, and (iii.) violence against women and the Istanbul Convention (the Convention on Preventing and Combating Violence Against Women and Domestic Violence). As a result, it demonstrates that young Muslim women’s dissident mentalities and subjectivities generate a new “political project”, i.e., a set of new meanings and social goals directed at bringing about social change, which comes into being through the act of resistance against RWP gender grammar and carves out new forms of knowledge reclaiming the Islam–gender nexus for a progressive feminist agenda.

Since its inception in 2013, the Arte Útil archive has become a collective steadily expanding as a tool for research and a resource for social practitioners. The archive is available for consultation at the website and consists of a growing database of around three hundred case studies that use art as a tool for societal change. It provides artistic strategies, a historical perspective, and a nexus between theory and praxis, besides being a platform to connect artistic projects and “users” from different geographies and contexts. Overall, it has become a nomadic pedagogical device able to trigger the discussion and the analysis of socially engaged art practice, its nature and its context involving not just artists but social agents and communities. As co-curators of the archive and educators, we interrogated ourselves regarding if curating as a social practice could expand the notion of education. Could we embrace the methodology of social practice to curate and generate pedagogical conditions fostering sustainability? Could we go beyond the conventional spaces and dynamics of academia? Could we integrate concepts like co-authorship and co-curating to cross from the arts to collective learning environments? How do we relate with the archive in other local contexts? In the last five years, we have implemented an evolving methodology that addresses all these questions, activating the Arte Útil archive as a pedagogical catalyst. The archive allowed collective experimentation and became a tool to infiltrate social practice both in the academic domain and galleries and museums’ educational ecosystems. In this article, we will analyse two different examples as case studies: from a research and artistic environment, a conversation with Onur Yıldız and Naz Kocadere, co-authors of “Art in use: case studies in Turkey” in May 2018, from a two-day workshop organised in collaboration with the Office of Useful Art at SALT Galata, Istanbul (TR); and from an educational perspective, the recent curriculum developed as part of the International Master Artists Educator (iMAE) in ArtEZ, Armhen (NL).

Water in the city is typically exploited in a linear process, in which most of it is polluted, treated, and discharged; during this process, valuable nutrients are lost in the treatment process instead of being cycled back and used in urban agriculture or green space. The purpose of this paper is to advance a new paradigm to close water cycles in cities via the implementation of nature-based solutions units (NBS_u), with a particular focus on building greening elements, such as green roofs (GRs) and vertical greening systems (VGS). The hypothesis is that such “circular systems” can provide substantial ecosystem services and minimize environmental degradation. Our method is twofold: we first examine these systems from a life-cycle point of view, assessing not only the inputs of conventional and alternative materials, but the ongoing input of water that is required for irrigation. Secondly, the evapotranspiration performance of VGS in Copenhagen, Berlin, Lisbon, Rome, Istanbul, and Tel Aviv, cities with different climatic, architectural, and sociocultural contexts have been simulated using a verticalized ET₀ approach, assessing rainwater runoff and greywater as irrigation resources. The water cycling performance of VGS in the mentioned cities would be sufficient at recycling 44% (Lisbon) to 100% (Berlin, Istanbul) of all accruing rainwater roof–runoff, if water shortages in dry months are bridged by greywater. Then, 27–53% of the greywater accruing in a building could be managed on its greened surface. In conclusion, we address the gaps in the current knowledge and policies identified in the different stages of analyses, such as the lack of comprehensive life cycle assessment studies that quantify the complete “water footprint” of building greening systems.

Violence against women is a significant sociological problem that negatively affects society. Although violence against women is widespread worldwide, the help-seeking behavior of women exposed to violence remains underdeveloped. In this study conducted in Turkey, the formal help-seeking behavior of women exposed to violence was studied according to sociodemographic factors. Data were obtained from surveys on domestic violence against women from the Turkish Statistical Institute (TURKSTAT), which was held in 2008 and 2014. Chi-square and binary logistic regression analyses are used in this study. The dependent variable is determined as whether women who had experienced violence sought help from formal institutions. In order to explain the dependent variable, education, age group, region, and sociodemographic variables are used. According to the results, as the education level of women exposed to violence increases, help-seeking behavior through official means also increases. In addition, women with a personal income are more likely to seek formal help than those without, and the development of the sociocultural region inhabited affects the formal help-seeking behavior of women exposed to violence. Between 2008 and 2014, legal regulations on women’s rights in Turkey were seen to positively affect formal help-seeking behavior. Although the formal help-seeking behavior of women subjected to violence in 2014 increased significantly compared to 2008, this improvement is not sufficient. Full article

Witnessing domestic violence (WDV) is recognized by the Istanbul Convention as psychological abuse that has dramatic consequences on the psychophysical health of children. Therefore, professionals who form the support network for WDV victims play a very fundamental role. In order to draw up useful guidelines for services dealing with WDV, and to give children more awareness of supportive settings, this study analyzes WDV in the perception of health and welfare professionals to enhance their skills and strategies for contrasting gender violence. Sixteen Neapolitan specialists dealing with WDV children were interviewed. A theoretical intentional sampling was used. Narrative focused interviews were carried out, transcribed verbatim and analyzed through the grounded theory methodology, using the ATLAS.ti 8 software (Scientific Software Development GmbH, Berlin, Germany). We assigned 319 codes and grouped these into 10 categories and 4 macro-categories. The analysis of the texts led to the definition of the core category as “The Crystal Fortress”. It summarizes the image of the WDV children as described by the professionals working in contrasting domestic violence. In this structure the parental roles of protection and care (fortress) are suspended and everything is extremely rigid, fragile and always at risk of a catastrophe. It also symbolizes the difficult role of health professionals in dealing with such children and their families. For WDV children, protective factors guarantee solid development and supportive settings help them to learn proper emotional responsiveness and expressiveness and to develop their skills in talking with adults while avoiding negative consequences.

This paper critically discusses the relation between human mobility and development. It moves away from conventional migration-development policy discussions that mainly focus on diaspora-like actors, who have established a stable and integrated socio-economic position in the destination countries. Instead, it looks at mobility-development dynamics in the context of less privileged and less integrated migrants; Nigerian migrants who are (or have been) living in transit-like situations in the city of Istanbul (Turkey). Based on in-depth interviews with Nigerian migrants, it analyses migrants’ personal developments in the light of their migration trajectories. The analysis particularly shows how upward social mobility is not so much found in onward migration to Europe, but in getting involved in a different form of mobility; informally arranged transnational trade between Turkey and West Africa. It outlines the diverse roles of migrants in this informal trade sector and elaborates on their relations with fly in/fly out traders originating from Africa. With these empirical insights, I conclude that these migrants do not belong to settled diaspora communities, but nevertheless, act as bridges between “here” and “there” and contribute to the creation of (new) development corridors.
