This study examines why currency substitution proves so difficult to reverse, even after countries succeed in stabilizing inflation. Focusing on Bolivia, Brazil, Mexico, and Turkey—economies that endured severe inflationary episodes before implementing stabilization programs—the paper asks a simple but important question: why does reliance on foreign currency persist long after inflation has been brought down? To answer this, the analysis adopts a structural time-series state-space framework that allows behavioral parameters to evolve gradually over time. Rather than assuming persistence, the model lets it emerge from the data and, crucially, compares alternative ways in which agents might form expectations about exchange rate movements. The evidence reveals a consistent pattern. By the end of the sample period, currency substitution remains statistically and economically significant in all four countries. The dominant expectation mechanism is extrapolative: agents tend to look at recent depreciation and assume it will continue. This tendency creates a reinforcing loop—when currencies depreciate, expectations of further depreciation strengthen, and the incentive to hold foreign currency intensifies. What makes these findings particularly striking is that this dynamic does not vanish once inflation is stabilized. Even in periods of relative macroeconomic calm, substitution persists. Past instability leaves a lasting imprint on expectations, and concerns about the durability of policy reforms continue to shape monetary behavior. In several cases, ongoing depreciation against the U.S. dollar further validates these cautious beliefs. As a result, the findings suggest that currency substitution is not merely a mechanical residue of past inflation. It is sustained by the way people form and update expectations in environments marked by credibility challenges. Stabilizing inflation is therefore a necessary step, but it is not enough on its own. Durable confidence in the domestic currency requires rebuilding credibility in a way that gradually reshapes expectations and restores trust over time. Full article

Achieving sustainable maritime transport requires comprehensive understanding of port-related emissions and evidence-based mitigation strategies. Maritime shipping significantly contributes to air pollution in port cities, threatening environmental sustainability and public health, yet comprehensive emission inventories remain scarce for major ports in developing economies. This study presents the first bottom-up emission inventory for Ambarlı Port, Turkey’s largest container port, utilizing AIS data from Global Fishing Watch for calendar year 2025. Emissions of CO₂, NO_x, SO₂, PM₁₀, PM_2.5, CO, and NMVOC were quantified using EMEP/EEA activity-based methodology with IMO Tier II emission factors and vessel type-specific load factors (75% for passenger, 45% for cargo) from ENTEC guidelines. Non-commercial vessels (tugs, service craft, fishing vessels) and lay-up vessels exceeding six months continuous berthing were excluded to focus on active commercial shipping operations, resulting in a validated dataset of 10,267 port visits from commercial cargo, passenger, and bunker vessels. Annual emissions from active commercial vessels totaled 404,766 tonnes CO₂, 8487 tonnes NO_x, 6724 tonnes SO₂, 914 tonnes PM₁₀, and 849 tonnes PM_2.5. Passenger vessels dominated the inventory (93.3% of CO₂) due to high auxiliary power demands for hotel services and elevated load factors, while cargo vessels contributed 6.5% despite representing 61.4% of port visits. Turkish-flagged vessels accounted for the majority of domestic ferry traffic. These findings provide baseline data for air quality management in the Istanbul metropolitan area and support policy development regarding shore power implementation, with particular emphasis on reducing emissions from passenger vessels with extended berth times. From a policy perspective, prioritized shore power investment at passenger ferry terminals emerges as the most cost-effective emission reduction strategy, with potential to eliminate over 90% of port-related air pollutant emissions through public-private partnership models.

This study assesses the technical feasibility of utilizing aggregated domestic freezers in Turkey as a distributed resource for frequency regulation. A dynamic thermal–electrical model was developed to simulate freezer responses under frequency deviation scenarios representative of real-world grid conditions. The modeled sample of 100,000 deep freezers (80 W each) can deliver approximately 3.2 MW of instantaneous down-regulation under a 40% initial duty cycle. Extrapolating to the estimated 4.7 million eligible freezers nationwide yields a total potential headroom of roughly 150–225 MW, depending on duty-cycle assumptions. The compressor duty cycle and allowable temperature range were identified as key factors influencing both regulation capacity and endurance. Although linear reference temperature control enabled effective participation in FCR-N within the simulated timeframes, it also led to cycle synchronization and peak loads following disturbances. Implementing strategies such as randomized reconnection delays could mitigate these effects. The wide availability of domestic freezers, minimal consumer impact, and broad geographic distribution suggest that this resource represents a promising complement to existing frequency regulation assets, particularly in enhancing grid stability amid increasing renewable energy penetration.

Animal welfare is a key component of sustainable poultry production and is routinely monitored through official veterinary inspections. The aim of this study was to determine the level of welfare compliance among different poultry species and production categories, to compare compliance levels across these groups, and to assess long-term trends using official inspection data. The study was based on the results of supervisory inspections conducted by veterinary inspectors in poultry farms in the Czech Republic between 2016 and 2024. Welfare compliance was evaluated in laying hens, broiler chickens, turkeys, ducks, and geese using a standardized system of welfare assessment checkpoints applied during official controls. Inspections were classified as compliant or non-compliant based on the presence or absence of deficiencies, and overall compliance levels were calculated as the proportion of animals kept in farms with compliant inspections. Across the entire study period, the proportion of poultry kept in farms with compliant inspections ranged from 82.8% to 98.4%, with the highest compliance level observed in turkeys, followed by ducks and broiler chickens, while the lowest compliance level was recorded in geese. Differences among poultry species and categories were statistically significant (p < 0.05). Comparison of two time periods (2016–2018 and 2022–2024) revealed significant improvements in compliance for broiler chickens, ducks, and geese, whereas significant declines were observed for laying hens and turkeys (p < 0.001). These results demonstrate clear differences in welfare compliance among poultry species and categories and indicate that compliance trends over time are not uniform across the poultry sector. Official veterinary inspection data provide a valuable tool for large-scale assessment of welfare compliance and for identifying poultry sectors that may benefit from targeted welfare improvement measures.

This article examines how Turkey’s 2024 amendment to the Animal Protection Law reshapes volunteer caregiving for free-roaming dogs in Istanbul by reconfiguring the practical conditions under which care is sought, coordinated, and sustained. Drawing on 43 in-depth interviews and five months of fieldwork (1 July–30 November 2025), this study combines constructivist grounded theory with reflexive thematic analysis to trace how legal change is encountered through everyday governance interfaces and how these encounters reorganize caregivers’ routines, capacities, and moral worlds. The analysis yields four interlocking findings. First, caregivers describe a temporality of “living in pre-loss,” in which anticipated removal, disappearance, and uncertain outcomes generate chronic vigilance, anticipatory grief, and ambiguous loss without closure. Second, caregiving is increasingly recalibrated as risk management: commitments persist, but intervention narrows through heightened exposure to complaints, reputational scrutiny, and fears that help-seeking may backfire. Third, institutional pathways—hotlines, shelter intake, and municipal responses—are experienced as discretionary and opaque, producing a fluctuating threshold between assistance and harm that conditions whether caregivers engage official systems at all. Fourth, this study identifies a recurring veterinary bottleneck at the street–clinic–recovery handover, where limited short-term holding capacity stalls treatment trajectories and displaces recovery labor into precarious domestic and informal spaces. Together, these findings argue that caregiver well-being is not ancillary to animal welfare governance but constitutive of it. It shapes the continuity of monitoring, the timeliness of intervention, and the everyday mediation through which coexistence is maintained under intensified legal and political pressure.

In emerging markets, stock markets play a crucial role in supporting long-term growth. This study explores the causal relationship between stock market development and economic growth in the Fragile Five countries—Brazil, India, Indonesia, South Africa, and Turkey—covering the period from 2001 to 2024. To ensure robust findings, it uses second-generation panel cointegration and causality tests that account for cross-sectional dependence and structural heterogeneity. The model includes three parameters representing financial depth, liquidity, and efficiency. Results indicate significant long-term cointegration, suggesting causality from stock market development to economic growth, supporting the supply-led growth hypothesis. This aligns with recent evidence highlighting the importance of institutional quality and sectoral interconnectedness in emerging markets. Furthermore, Panel DOLS and FMOLS analyses reveal that stock market capitalization has a notable positive effect on domestic productivity. Overall, these findings underscore that stock market parameters are vital for accurate economic forecasting and that strengthening capital markets is essential for sustainable growth in the Fragile Five.

This article examines how the Ahiska Turks—deported from Georgia’s Meskheti region to Central Asia in 1944—sustained their religious belonging under shifting Soviet and post-Soviet political and social conditions, and how this religious continuity became intertwined with processes of collective memory formation. Drawing on published archival materials, existing scholarship, and a long-term ethnographic corpus composed of fourteen life-history oral interviews conducted between 2006 and 2025 in Turkey and Kazakhstan, the study traces the multigenerational trajectories of ritual practice. The findings show that funeral ceremonies, mevlid gatherings, Ramadan practices, and domestic prayer circles function as “sites of memory” through which the trauma of displacement is reinterpreted and intergenerational belonging is continually reconstituted. These ritual forms generate a meaningful sense of continuity and communal resilience in the face of prolonged experiences of loss, uncertainty, and “placelessness.” Situated at the intersection of the anthropology of religion, cultural trauma theory, and Soviet/post-Soviet diaspora studies, the article conceptualizes Islam as more than a realm of belief: for the Ahiska Turks, it operates as a core cultural infrastructure that anchors post-displacement resilience, social organization, and collective memory. The study contributes to the literature by offering an integrated analytical framework that places the Ahiska community within broader debates on religion, memory, and forced migration; by examining rituals not only as emotional practices but also as institutional and cultural scaffolding; and by foregrounding the understudied post-traumatic religious experiences of Muslim diasporas.

The entire ecology is obviously being significantly impacted by climate change. Its causes must be found and addressed before it can be prevented. Therefore, this research investigates the impact of Green Production Processes (GRPP), Technological Globalization (TGLO), Renewable Energy Consumption (RECN) and Gross Domestic Product (GDP) on ECOF (Ecological Footprint) in Turkey from 1990 to 2022 using the Autoregressive Distributed Lag (ARDL) and Frequency Domain Causality methods. The E-Views 12 statistical software was used for the ARDL analysis, while the STATA 17 software was used for the Frequency Domain Causality. The ARDL outcome in the long run showed that GRPP and GDP contribute to ECOF significantly, while TGLO and RECN reduce ECOF insignificantly. The implication of this is that GRPP and GDP lead to ecological degradation, while TGLO and RECN contribute to ecological quality negligibly. In the short run, TGLO reduces ECOF, while GDP increases ECOF. This means that TGLO drives ecological quality, while GDP reduces it. Furthermore, the outcome of the Frequency Domain Causality confirms that GRPP and TGLO Granger-cause ECOF in the short, medium and long term. RECN, on the other hand, only Granger-causes ECOF in the long run, while there is no causal relationship between GDP and ECOF. This study recommends stringent environmental policies and investments in clean energy technologies, such as renewable energy. Full article

The Republic of Turkey established its first match factory in Sinop in 1929 but had to relocate it even before it was in operation due to severe structural damage caused by ground settlement. In July 1930, through his US-based firm the American–Turkish Investment Corporation (ATIC), the Swedish “Match King” Ivar Kreuger signed a contract with the Republic of Turkey to build and operate a factory in Büyükdere, Istanbul. By 1930, Kreuger had already established a match production monopoly in nearly every country in Europe and that year created a similar financial system for Turkey, gaining control of match production for 25 years. This article explains the events surrounding the establishment of his modern production facility in Turkey, with a particular focus on its engineering aspects. It details the strategically chosen location, the engineering solutions for the factory’s construction, its production lines, and what the country gained and lost from it. In order to determine the establishment and production processes of the facility, the authors examined domestic and foreign archival documents, firsthand news reports from the period, articles and theses, and all other available documents. After the contract was terminated by both parties, the Turkish government and ATIC, in May 1943, the factory continued its production and storage activities until May 1989. At that point, the factory and all its equipment were integrated into another existing facility in the İnegöl district of Bursa province. Almost all the buildings of the Büyükdere Match Factory were demolished, and the land was repurposed for a 450-bed regional hospital in 2012. In short, this article deploys the Büyükdere Match Factory as a case study to examine what Turkey gained and lost from the establishment and production processes of a modern industrial factory, enabled by US–Turkish collaboration, and equipped with the most advanced manufacturing and engineering technologies of the time.

Riemerella anatipestifer (R. anatipestifer, RA) is a globally distributed pathogen responsible for duck serositis, an acute multisystemic disease whose infection leads to substantial economic impacts in duck production. There is currently no specific therapeutic drug available for effective treatment. Importantly, the severity of the disease is closely associated with multiple environmental factors, including feeding conditions, management practices, weather fluctuations, and air quality parameters. Furthermore, the prevalence of various serotypes is a matter of concern, and the emergence of multi-drug-resistant mutants through continuous use of various antibiotics is a major challenge. Recently, it has been reported that RA infects domestic ducks, turkeys, geese, wild birds and chicken, which leads to its remarkable influence on the healthy development of waterfowl breeding industry and even poultry breeding industry. Given these challenges, vaccination is essential for disease control. Various vaccine types are currently available, including but not limited to live vaccines, inactivated vaccines, subunit vaccines and vector vaccines. This paper provides a comprehensive review of the development of vaccines for RA. Full article

The morphological diversity of the domestic turkey is still an open question in poultry research. For this reason, a meta-analysis with 97 reports from 28 morphometric characterization studies covering 15 different turkey genotypes was carried out in the present study. Biometric measurements and indices collected from the articles were used as independent variables in three principal component analyses. The highest variance explaining power was achieved in the analysis including only biometric indices, with more than 70% in the first two principal components for both sexes. The ‘leg length’, ‘body mass’, ‘shape’, and ‘tarsus’ indices were those with higher explanatory power, the latter two particularly so in females. In addition, ‘head’ was such a high variance explaining body region, especially in males, while for females, the ‘leg’ showed high variability between breeds. The spatial representation of observations drew an interesting grouping pattern, proposing an ‘African’ and ‘Mediterranean’ trunk of turkeys based just on biometric traits. The correlation matrix showed positive and negative associations between the variables, especially stronger in females. Breast circumference was negatively correlated with weight and size traits, suggesting that turkey landraces differ in body conformation and environmental requirements. Despite data limitations, particularly in terms of available breed reports and measures taken, consistent results were obtained. The results of the present work could be common guidelines for the phenotypic characterization of turkey breeds worldwide. Full article

The study investigates the contribution of technology (TECH), quantified by Internet penetration, in influencing tourism performance (TP) among the top ten touristic nations in Europe: France, Spain, Italy, Turkey, the United Kingdom, Germany, Greece, Austria, Portugal, and the Netherlands. Using panel data from 2000–2022, the study includes additional structural controls like environment quality, gross domestic production (GDP) per capita, exchange rate (ER), and safety index (SI). The Method of Moments Quantile Regression (MMQR) is employed to capture heterogeneous effects at different levels of TP, and Driscoll–Kraay standard error (DKSE) correction is employed to make the analysis robust against autocorrelation as well as cross-sectional dependence. Spectral–Granger causality tests are also conducted to check short- and long-run dynamics in the relationships. Empirical results are that TECH and SI are important in TP at all quantiles, but with stronger effects for lower-performing countries. Environmental quality (EQ) and GDP per capita (GDPPC) exert increasing impacts at upper quantiles, suggesting their importance in sustaining high-level tourism economies. ER effects are limited and primarily short-term. The findings highlight the need for integrated digital, environmental, and economic policies to achieve sustainable tourism development. The paper contributes to tourism research by providing a comprehensive, frequency-sensitive, and distributional analysis of macroeconomic determinants of tourism in highly developed European tourist destinations.

The sustainable preservation of archeological heritage located in rural and coastal regions requires more than technical interventions; it necessitates the awareness and active participation of local communities. However, community involvement in heritage management in such areas remains limited. This study aims to analyze the levels of cultural heritage awareness, conservation tendencies, and tourism-related expectations among local residents and visitors in the Magarsus Archeological Area, located in the Karataş district on the eastern Mediterranean coast of Turkey. The study was conducted in three phases: a literature review, field observations, and a structured survey conducted between June and August 2022 with 510 participants (280 local residents and 230 domestic visitors from surrounding provinces). The data were analyzed using SPSS 25.0 through descriptive statistical methods, complemented by cross-tabulation and chi-square analysis to identify patterns across demographic variables. The survey results not only reflect general perceptions about heritage and tourism but also offer critical insights into how the rural and coastal character of the site shapes conservation attitudes and tourism behavior. The findings reveal nuanced perceptions, including strong symbolic appreciation for heritage and general openness to tourism, alongside concerns about cultural and environmental risks. While the local community prioritizes the potential for economic benefit, many participants also emphasized the importance of safeguarding local traditions, crafts, and culinary heritage. Nevertheless, concerns were expressed regarding the risks posed by uncontrolled tourism, including environmental degradation, erosion of cultural identity, and the commodification of heritage values. Based on these insights, the study introduces a governance approach built upon three interlinked pillars: community-based participation, environmental sustainability, and tourism practices aligned with cultural values. The proposed approach aims to support the inclusive and sustainable management of Magarsus and other rural and coastal archeological landscapes with similar characteristics. Full article

Aedes aegypti is the primary vector of arboviral diseases such as dengue, chikungunya, yellow fever, and Zika, posing significant global health and economic challenges. The effective control of this mosquito species requires understanding its seasonality, feeding behavior, and ecological dynamics. Modern molecular techniques, such as amplicon metagenomic sequencing, provide insights into vector–host interactions and feeding patterns. This study investigated the temporal variation of Ae. aegypti abundance and its blood meal sources in coastal and western Kenya over 16 months. A total of 64,360 mosquitoes were collected, with Ae. aegypti comprising 10.9% (7035/64,360). Coastal sites had a higher proportion (64.7%) of Ae. aegypti than western Kenya. Seasonal variation in abundance was observed, with peaks during the long rainy season and decline during the dry season. Blood meal analysis identified 15 vertebrate hosts, with humans being the primary source (86.6–95.9%). Other hosts included domestic animals such as turkey, sheep, cow, goat, and chicken. These findings highlight the role of rainfall in arboviral disease transmission and Ae. aegypti’s strong preference for human hosts. Additionally, this study demonstrates the cost-effectiveness of group testing for identifying blood meal sources, with implications for public health interventions. Full article

The poultry industry is a critical source of affordable protein worldwide; however, it faces continuous threats from various poultry diseases that significantly impact public health, economic stability, and food security. Knowledge of and examination of the transmission routes, risk factors, and environmental survival characteristics of the most important pathogens affecting poultry populations, as well as the importance of strict biosecurity, are pivotal. Transmission routes are split into direct and vector-borne pathways, and indirect ways, which include infections via contaminated surfaces and vector-borne pathways, including insects and rodents. Avian influenza virus and Newcastle disease virus spread through respiratory droplets, and their transmission risk increases with increasing stocking density. While other pathogens (e.g., infectious bursal disease virus and Salmonella spp.), to persist long-term in the environments, for example, feed and litter, increasing the probability to persist long-term in the environments, for example, feed and litter, increasing the probability of infection. The long-term resilience of pathogens in multiple pathogens in various environmental conditions highlights the role of biosecurity, sanitation, and hygiene controls in preventing disease outbreaks. High stocking density in production systems, suboptimal ventilation, and inadequate biosecurity controls further increase transmission risks. This paper summarizes important disease transmissions and reinforces the need for strict biosecurity protocols and routine health monitoring to prevent the spread of pathogens within and beyond poultry facilities. These strategies can support safe poultry production, address growing global demand, and ensure food safety and public health. Full article
