Secure Optical Coded GSSK System with Dimming
(IEEE, 2024) Hassan, Sumeyra; Panayirci, Erdal; Helleseth, Tor; Poor, H. Vincent
In this work, we develop an indoor visible light communications (VLC) system based on a transmitted precoded (TPC)-aided, coded generalized space shift keying (GSSK) system with physical layer security (PLS) capability in the presence of dimming. A new design of the encoder and decoder of linear codes is given to improve the error-correcting capability of the system as well as to enable random selection of the activated indices in the GSSK automatically. The PLS of the system is guaranteed by the appropriate selection of the power allocation coefficients for randomly activated photodiodes (PDs). At the receiver, the unknown channel and dimming coefficients are jointly estimated in the legitimate users with a new pilot-aided estimation technique. Then, the optimal detection of the spatial symbols is implemented using the maximum likelihood (ML) criterion in the presence of dimming. It is shown that the dimming coefficients, unknown to the eavesdropper, provide additional PLS for the legitimate user. The computer simulations show that the legitimate user achieves excellent bit error performance mainly due to the linear coding employed that serves for error correction and selection of the best GSSK constellation in the system. In contrast, the bit error performance of the potential eavesdroppers is significantly degraded.
Moral Framing Effects on Environmental Attitudes: A Conceptual Replication and Extension of Feinberg and Willer (2013)
(Academic Press Ltd- Elsevier Science Ltd, 2025) Cavdar, Dilara; Tepe, Beyza; Saribay, S. Adil; Yilmaz, Onurcan
This study investigates the relationship between moral framing, political orientation, and pro-environmental attitudes, replicating and extending Feinberg and Willer (2013) in a non-Western context. Using a Turkish-speaking sample (N = 699), we examined the effectiveness of care and sanctity-framed messages and the moderating role of actively open-minded thinking (AOT). Our findings partially replicated the original study. Sanctity framing increased pro-environmental attitudes among conservatives, while care framing had no significant effect. Political conservatism was negatively associated with pro-environmental attitudes, confirming prior findings. Exploratory analyses revealed that AOT moderated the effects of sanctity framing on environmental attitudes, with individuals low or moderate in AOT being more responsive. Both care and sanctity frames increased environmental donation, addressing the intention-behavior gap. However, cultural nuances, such as the collectivist orientation of the sample, may have influenced the care frame's ineffectiveness. The study highlights the importance of cultural context in moral framing research and underscores the need for context-specific climate communication strategies.
Exploring the Relation between Gesture Presentation Perspective and Children's Spatial Performance
(John Benjamins Publishing Co, 2025) Orakci-Beyaztas, Elif; Karadoller, Dilay Z.
The study investigated whether the perspective of multimodal input in visuospatial maps predicts children's spatial performance, particularly verbal recall and direction-following behavior. 5-year-old monolingual Turkish children were engaged in the Directions Task, which included visuospatial maps and videos of a speaker describing routes on maps in three conditions: Speech-Gesture combination with a front-facing view, Speech-Gesture combination with an upper back angle, and Speech-only condition with a front-facing view for control. Children were asked to verbally recall and draw the route described in the videos. They also engaged in perspective-taking, mental rotation, and relational reasoning tasks. Results showed that children's verbal recall, but not necessarily behavioral recall, was enhanced by receiving multimodal directions. Moreover, children's relational reasoning and perspective-taking abilities modulate their verbal recall performances. The results of this study underline the importance of multimodal input and presentation perspective in enhancing children's spatial performance.
Visualizing Children's Health: Transformation of the Turkish State's Biopolitical Communication from Tuberculosis to COVID-19
(Sage Publications Ltd, 2025) Arda, Balca; Ilikan Rasimoglu, Ceren Gulser; Guney, K. Murat
This article comparatively explores two distinct cases of children's health communication on tuberculosis in the interwar period, and COVID-19, to trace the development of biopolitical governance in Turkey. Biopolitical visuality encompasses affective sensibilities and imaginations about the nation by conveying multilayered discourses. Public health discourse aims to ensure the health and optimal development of adult-to-be citizens and to provide strategies for improving parents' and communities' awareness of children's health. Our critical multimodal discourse analysis, based on our T & Uuml;B & Idot;TAK 3005 (Scientific & Technological Research Council of T & uuml;rkiye)-funded project, 'Analysis of Public Health Visual Communication Methods', demonstrates traits of biopolitical extension through contextual emphasis. We compare the imagery of children through a specific section of the Ya & scedil;amak Yolu journal to official visual health communication materials addressing child health during the COVID-19 pandemic in Turkey. We contend that visual discourse on the consideration of medical science, the relation of mental health to the physical and the gender roles of parents, progressively supports an individuation of biopolitics. We conclude that while early Republican visuals allowed some interpretive freedom through enabling a reformulative agency for the citizen subject in pursuit of well-being, the neoliberal era's COVID-19 materials intensified pedagogical control and individualized responsibility, especially within the family, which expanded biopolitical governance into the routines of everyday life.
Reshaping Globular Dynamics of S. Aureus Pyruvate Kinase via Bond Restraints to Allosteric Sites
(Springer, 2025) Fidan, Vahap Gazi; Aydin, Dilvin; Yazgi, Irem; Akten, E. Demet
The global dynamics of pyruvate kinase were examined using molecular dynamics (MD) simulations to investigate the effects of allosteric inhibition through bond restraints applied at two key allosteric sites. The study employed the experimentally resolved structure of the enzyme complexed with the allosteric inhibitor IS-130 at the small C-C interface, serving as a reference for analyzing an additional, computationally predicted allosteric site at the large A-A interface. Simulations identified the B and CT domains as the most mobile regions, with bond restraints at either interface significantly reducing CT domain flexibility up to 9 & Aring; across all chains. Restraints at the C-C interface limited minimal global conformational sampling, whereas restraints at the A-A interface altered the dynamic profile without narrowing the sampled conformational space, suggesting distinct regulatory roles for each interface. Distance fluctuation analyses revealed enhanced interchain communication and reduced mobility near restrained sites, suggesting that these restraints reinforce allosteric inhibition by stabilizing otherwise flexible domains. Cross-correlation analysis showed a marked reduction in long-range residue-residue correspondence, especially under C-C restraints, indicating disrupted dynamic coordination essential for catalytic activity. Mutual information analysis, capturing both linear and non-linear dependencies, further supported these findings by showing a widespread loss of dynamic correspondence in positional fluctuations across the receptor upon restraint application. Notably, although the C-C interface has been experimentally linked to inhibition, these results suggest that the computationally predicted large A-A interface may also contribute to allosteric regulation. Together, these findings highlight the distributed and cooperative nature of allosteric control in pyruvate kinase.
A Polish Adaptation of the Autobiographical Recollection Test (ART): Toward a Reliable and Valid Measure of Individual Differences in Autobiographical Memory
(Routledge Journals, Taylor & Francis Ltd, 2025) Barzykowski, Krystian; Ilczuk, Ewa; Oner, Sezin; Chwilka, Paulina; Wereszczynski, Michal
Although previous research has extensively examined the characteristics of specific autobiographical memories, few tools have been available to assess how individuals recall their personal past in general. To address this gap, we adapted into Polish the Autobiographical Recollection Test (ART), a self-report instrument originally designed to capture general autobiographical remembering across seven components: vividness, narrative coherence, reliving, rehearsal, scene construction, visual imagery, and life story relevance. Confirmatory factor analysis supported the factorial validity of the Polish version, demonstrating adequate psychometric properties. The Polish adaptation also showed expected correlations with another self-report measure of autobiographical memory ability (Survey of Autobiographical Memory, SAM), supporting its convergent validity. Furthermore, both the full and brief versions of ART showed significant associations with scores on the Involuntary Autobiographical Memory Inventory (IAMI). These findings provide robust support for the Polish adaptation of ART as a reliable tool for assessing the subjective qualities of autobiographical memory, with potential applications in research on diverse populations.
Fighting Authoritarian Populism with Populism in Polarised Turkey
(John Benjamins Publishing Co, 2025) Way, Lyndon C. S.; McLoughlin, Stephen; Inceoglu, Irem
Globally, populism is on the rise. Studies demonstrate how populism is a 'thin' ideology that is articulated with ideologies ranging from authoritarianism to its challenges. Here, we examine how two politicians who, at similar times in their careers, represented themselves as inclusive and democratic, yet articulated different incarnations of populism. One of these (Turkish President Erdo & gbreve;an) has since become an authoritarian populist and the other (Ekrem & Idot;mamo & gbreve;lu), Erdo & gbreve;an's political opposition. Both & Idot;mamo & gbreve;lu in 2019 and Erdo & gbreve;an in 1994 were first elected as Istanbul's mayor. Using Critical Discourse Analysis, we analyse their public utterances around the times of these mayoral victories. This close reading reveals how discursive strategies are used in Erdo & gbreve;an's utterances that articulate the seeds of authoritarian populism while & Idot;mamo & gbreve;lu, 25 years later, uses populism to challenge these. This study offers insights into how populism can be employed to both articulate and challenge authoritarian populism.
Assessing the Impact of Customer Experience Quality on Customer Perceived Value and Marketing Outcomes
(Taylor & Francis Ltd, 2025) Demir, Ozge; Karaosmanoglu, Elif; Uray, Nimet
This research explores the link between customer experience, value, and marketing outcomes, with emphasis on contextual adaptability, employing a multi-group structural equations modeling (SEM) approach. It shows that customer experience quality (CXQ) is invariant across two services, banking and TV broadcasting. SEM results demonstrate that customer loyalty is mainly influenced by functional value-more so than economic or social values. However, what drives functional value differ: For banking, consumers' evaluations of three CXQ dimensions, ease of access, monetary experience, and customer-centric processes predict functional value. In the TV subscription service however, functional value is largely driven by customer-centric processes.
Understanding Customer Conversations in Social Media Support Interactions: Divergent Sentiments in Material and Experiential Brands
(Emerald Group Publishing Ltd, 2025) Kiygi-Calli, Meltem; Merdin-Uygur, Ezgi; Onden, Abdullah; El Oraiby, Maryam
PurposeThis study aims to investigate how customer sentiments differ in social media interactions with customer support accounts of material and experiential brands. It seeks to understand the impact of these interactions on customer sentiment dynamics and their implications for customer support strategies.Design/methodology/approachDrawing on experiential recommendation literature, this study employs a sentiment analysis approach to analyze 60,000 tweets directed at customer support accounts of three experiential and three material brands on X (formerly known as Twitter). Regression analysis is also applied to investigate the influence of post characteristics and content types (e.g. emojis) on sentiment.FindingsResults reveal significant differences between material and experiential brands in both overall sentiment and sentiment evolution during customer support interactions. Conversations with experiential brands exhibit more positive overall sentiments; whereas interactions with material brands demonstrate a greater positive sentiment shift despite initially exhibiting more negative sentiments. The findings also show that tweet length is a strong predictor of customer sentiment.Originality/valueThis research underscores the unique roles of material and experiential brands in shaping customer sentiment during social media interactions. The study provides novel insights into online customer support dynamics and offers actionable recommendations for improving after-sales management strategies in social media contexts.
Multi-Objective Optimization of P2P Energy Trading for Consumer-Prosumer Benefits and Reliability Improvement in LV Distribution Grids
(Elsevier, 2025) Polat, Keysan; Ahmadi, Bahman; Ozdemir, Aydogan
Integrating distributed generation into the main grid requires the active participation of both consumers and prosumers, offering technical and financial benefits for all stakeholders. This study proposes a multi-objective optimization approach to enhance peer-to-peer (P2P) market operations within low-voltage distribution grids. It focuses on optimizing the placement of modular PV panels, maximizing prosumer profits, and refining P2P strategies. Key objectives include minimizing the payback periods for PV owners and reducing the average monthly energy costs for consumers. The Multi-Objective Advanced Gray Wolf Optimizer (MOAGWO) is used as the solution method. Operational scenarios are also compared from a consumer reliability perspective as an assessment metric. The methodology is applied to a 55-node European low-voltage test feeder across six scenarios. Results indicate that prosumer payback periods remain around eight years for up to four prosumers but increase with further installations. Average monthly energy costs for customers ranged from 653 to 1079. A quality assessment based on three multi-objective optimization metrics showed that MOAGWO and MOGWO yielded comparable performances.
The State Gives Me the Right Not to Do It: Reproductive Governance, Structural Violence and Barriers to Abortion Care in Türkiye
(Pergamon-Elsevier Science Ltd, 2026) O'neil, Mary Lou; Gogus, Eylem Mercimek; Degirmenci, Selma
Abortion in T & uuml;rkiye is legal through ten weeks gestation without restriction as to reason, but it is often difficult to access. In recent years Turkey has undertaken an aggressive pronatalist politics of reproduction resulting in extensive reproductive governance that regulates reproductive health care in general and abortion access in specific. This research uses nationwide data collected in 2024 from public and private hospitals to ascertain the availability of abortion in T & uuml;rkiye. Currently, less than one third of hospitals report providing abortion care but this drops to just 5.1 % for public hospitals while 50.4 % of private hospitals offer abortion services. However, the lack of availability does not rely on simply denial but encompasses a multilayered system of barriers that restrict access. While some institutions simply stated that they do not perform abortions, many others cited varying obstacles that hindered their ability to provide such care. These included declarations that abortion is illegal, doctors' refusal to perform abortions, and use of gestational limits less than the ten weeks provided in law. Adding to these barriers is the lack of available information about abortion availability, the substantial distances required to travel to access care, and the price of abortion at private hospitals. By limiting abortion access, the state undermines individual autonomy and endangers the health and safety of pregnant people. In practice, legality offers little protection: the combination of institutional refusal, misinformation, geographic and financial hurdles, and political hostility makes abortion effectively inaccessible for many. T & uuml;rkiye's case illustrates how legal rights can be hollowed out by restrictive governance, leaving reproductive freedom precarious despite formal legality.
An Assessment of the Current State of Turkish Law in Light of the Reforms Introduced by Directive 2024/2853 on Product Liability
(Istanbul Univ, Fac Law, 2025) Caliskan, Alican; Yildirim, Kaan Can
This study examines the significant reforms introduced by the European Union's New Product Liability Directive (2024/2853) and evaluates the current status of Turkish product liability law in light of these changes. The former Directive 85/374, in force for nearly 40 years, had become outdated due to rapid technological advancements and digitalization. The new Directive responds to these developments by explicitly including software and artificial intelligence within the definition of "product," introducing presumptions that ease the burden of proof for injured parties, expanding liability to cover not only manufacturers but also broader economic operators, and redefining the moment of liability to include, under certain circumstances, the lifecycle of the product-not just its release date. In this way, it is intended to make it easier for those injured to access broader protection in a more convenient way. In Turkish law, although Law No. 7223 on Product Safety and Technical Regulations, enacted in 2020, officially introduced strict liability for producers, it diverges significantly from the new Directive in key areas. The definition of product excludes intangible digital products like software, no presumptions are provided in favor of injured parties, and the concept of "nonconformity" is framed narrowly around technical regulatory compliance rather than user safety expectations. The article concludes that Turkey's product liability regime, although relatively recent, is already outdated in the face of modern challenges and EU standards. For meaningful alignment and effective user protection in the digital age, the Turkish framework must be revised to better reflect the core objectives and modern scope of the new EU Directive.
Infants' Background Television Exposure and Maternal Language Input: A Home Observation Study
(Cambridge Univ Press, 2025) Kessafoglu, Dilara; Yildiz, Ezgi; Kuntay, Aylin C.; Uzundag, Berna A.
Parental reports and experimental studies indicate that parents speak less to their children in the presence of background television. However, there is a lack of home observations examining the relations between infants' background TV exposure and maternal infant-directed speech. In the current study, 32 infants and their mothers were observed for 60 minutes in their homes at 8, 10, and 18 months of age. Results revealed that the number of words, the number of different words, and the number of questions in infant-directed speech were consistently lower in households with background TV. Furthermore, these aspects of maternal language input were negatively related to the duration of background TV, controlling for families' socioeconomic background. These findings suggest that television may have a negative impact on young children's language development via disrupted parent-child interactions in the presence of background TV in the home environment.

Why I Declare a Conflict of Interest and You Should Not
(Springer, 2025) Acem, Ensar; Aczel, Balazs; Albayrak, Nihan; Brown, Nicholas J. L.; Dudda, Leonie A.; Elsherif, Mahmoud Medhat; Zubaly, Benjamin
Academic publishing is both an indication of scientific contribution and a currency for career advancement. This dual role gives rise to a normative scientific conflict: Does the structural incentive to publish constitute a conflict of interest (COI) that ought to be disclosed? In this paper, we address this conflict through an action research approach, engaging collaboratively and reflexively to answer four related questions: (1) What evidence suggests that researchers face a (financial) COI when publishing? (2) What are the benefits and drawbacks of explicitly acknowledging that publications function as academic currency? (3) How should such conflicts be disclosed? (4) Do mechanisms such as pre-registration and registered reports resolve these concerns? This paper contends that while researchers are clearly incentivised to publish, this interest need not necessarily constitute a conflict or be explicitly disclosed. Treating this issue as a normative scientific conflict does reveal the need for a shift in how researchers understand and navigate the subjective, self-interested dimensions of their work. We propose four key responses: (1) integrating discussions of COIs and biases more extensively into undergraduate science education, (2) promoting greater reflexivity in everyday research practice (e.g., through reflexivity journals, peer-led audit groups, and the reintegration of discussions on the historicity and cultural nature of research into scientific publications), (3) critically investigating institutional incentives and journal policies, and (4) proactively adopting methodological safeguards such as pre-registration. By addressing this conflict through action research, we demonstrate how normative tensions in science can be made productive - supporting both critical reflection and structural improvement.
An Experimental Study for Analysing Pricing Decisions Under Competition
(Oxford Univ Press, 2025) Ayvaz-Cavdaroglu, Nur; Aktunc, Esra Agca; Erkol, Cuneyt
Accepted by: M. Zied BabaiAlthough pricing models of revenue management can considerably improve the profitability of firms, it is not evident whether real-life decision-makers follow them precisely in making price decisions. The effect of sequential anchors on the pricing decisions especially remains understudied. This study aims to investigate the decision-making patterns of human beings in setting prices for homogeneous goods in a competitive market. Two laboratory experiments have been designed and conducted, the former involving a competitor firm with a fixed price, while in the latter, the competitor's price changes over time. The results show that decision-makers are more prone to the 'anchoring effect' when they encounter varying competitor prices. This bias could override the learning effect and is not statistically different across the two genders. Moreover, 'underpricing' is frequently observed in this setting, and a higher variance in demand could deteriorate the quality of pricing decisions. The competitor's prices act as sequential anchors, and several insights are derived regarding the size and extent of anchoring tendency under various patterns of sequential anchors. More generally, the results of the experiment bring practical insights regarding how to enhance pricing decisions for managers in stochastic demand settings with varying parameters.
Optimizing Location Selection for Foreign Trade Intelligence Centres Using Spherical Fuzzy Methods
(Pergamon-Elsevier Science Ltd, 2026) Gorcun, Omer Faruk; Cizmecioglu, Sinan; Boz, Esra; Calik, Ahmet
This investigation focuses on a vital research topic that has significant research gaps in the literature, such as the selection of locations for foreign trade intelligence centres, which have a critical role in a country's development, a country's development and export capabilities. Previous studies have primarily addressed site selection in the context of manufacturing industries and retail outlets, focusing on strategies, and often ignored the unique requirements of foreign trade intelligence operations. This study solves the problem by considering the requirements of an innovative and integrated decision-making approach developed in the context of foreign trade intelligence centres, while at the same time filling the relevant research gap. The proposed model provides a mathematical form by extending Delphi management with spherical fuzzy sets to highlight influential evaluation criteria, as well as providing an integrated decision-making model extended with spherical fuzzy numbers to assess alternatives and determine rankings. Ten primary evaluation criteria are established to present a set of criteria for the authorities. The importance level of the criteria and assessments of alternatives for these criteria are aggregated spherical fuzzy numbers. A mixed integer non-linear multi-objective mathematical model is developed for the previous stages' outputs and different parameters. The results of the empirical application in Turkey show that Mersin is the most suitable alternative due to its attractive government incentives and strong commercial vitality compared to other options. The robustness checks verified the model's validity and reliability, proving a consistent decision-making tool for decision-makers and policymakers in the context of systematic decision-making.
Beyond the Screen: The Impact of TV Series on Visit and Purchase Intentions
(Emerald Group Publishing Ltd, 2025) Tosun, Petek; Uslu, Abdullah; Yanar Gurce, Merve
PurposeDrawing on parasocial relationship theory and the meaning transfer model, this study suggests and tests an original model that examines viewers' intentions to visit a destination and purchase destination origin products, considering cultural proximity, celebrity involvement, enjoyment, country knowledge obtained via TV series and perceived product experience.Design/methodology/approachTurkish TV dramas were selected as the research context due to the increased global attention in the last decades. A field survey was conducted on foreign tourists in T & uuml;rkiye. The research model was tested with PLS-SEM.FindingsCultural proximity is positively related to celebrity involvement and enjoyment, influencing country knowledge and the intention to purchase the country's products. Celebrity involvement and country knowledge positively influence visit intentions. Moreover, the perceived product experience is positively related to purchase intentions.Practical implicationsTV dramas can significantly leverage international purchase intentions and promote destination-specific products in global markets, particularly with celebrity endorsements. Producers and marketers can strategically integrate cultural and local elements into TV dramas to enhance destination marketing strategies.Social implicationsTV dramas can deepen intercultural understanding by enhancing foreign viewers' knowledge of the origin country's culture, values, and lifestyle. By building emotional connections through media characters, countries can develop positive perceptions of each other and develop social affinities with one another, which can impact travel and consumption patterns.Originality/valueThis study shows the positive impact of TV series enjoyment on the country knowledge and perceived product experience regarding the origin country of TV dramas.
Exploring Children's Causal Language Production: The Role of Mothers and Fathers Across Different Tasks in Dyadic Interactions
(Cambridge Univ Press, 2025) Kandemir, Songul; Aktan-Erciyes, Asli
Causal language is essential for children's language development, helping them understand and explain the reasons behind events. This study focuses on children's causal language production and the role of parental input, aiming to (1) investigate differences in maternal and paternal language use, (2) analyse children's causal language production across tasks and communication partners, and (3) examine the relationship between parental input and children's causal language skills. Sixty children aged 4-5 and their parents participated in dyadic sessions, which included free play, guided play, and storytelling tasks. Results showed that fathers used more causal language than mothers during free play, and children also produced more causal language with their fathers in this context compared to storytelling. Overall, both maternal and paternal causal language inputs were linked to children's causal language production, highlighting the significant influence of parental input on language development.

Evaluation of Railway Intelligent Transportation Systems to Construct Safer Railway Transport Systems with a Novel Decision-Making Model
(Elsevier Sci Ltd, 2026) Gorcun, Omer Faruk; Hussain, Abrar; Ullah, Kifayat; Pamucar, Dragan; Simic, Vladimir
While end users typically perceive rail transport as safer than other forms of transportation, it still confronts substantial threats and risks that demand meticulous management. One of the most crucial challenges in rail transport is the management of dense railway traffic on limited infrastructure. The effectiveness of this management is critical to ensuring safety and reliability. To address these challenges, integrating and adapting Railway Intelligent Transportation Systems (RITS) into railway transport systems has become essential for creating a safer and more reliable railway system. A railway system that is poorly structured and does not use advanced technology appropriately struggles to manage these risks effectively. Therefore, the integration of RITS is crucial. Decision-makers must carefully evaluate and select the most suitable RITS to ensure safety and reliability. However, since many conflicting criteria and decision factors affect the evaluation process, selecting the most appropriate RITS is a complex decision problem. This study proposes a new decision-making model by considering these requirements. In this context, the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method, enhanced with Intuitionistic Fuzzy Sets and reinforced by integrating Schweizer-Sklar Hamy Mean Operators, was developed as a practical solution to address the decision-making problem. According to the research results, reliability and the use of the most advanced technology are the effective criteria that influence the selection of appropriate RITSs. In addition, A3 Aselsan, one of the key players in the intelligent transport system manufacturing industry, has been determined to be the most suitable alternative for railway transportation systems. Ultimately, extensive reality tests involving sensitivity and comparative analysis were conducted to check the robustness of the model. The analysis proves the model's soundness and practicality.
Determination of Sustainable Areas for Ecotourism Using GIS-Based AHP
(Taylor & Francis Ltd, 2025) Kaya, Sude Nur; Genc, Levent; Kozak, Metin
The study aims to select locations suitable for ecotourism, which has become an important concept for developing countries because of its significance in biodiversity conservation, the growing awareness of sustainability, and the increasing demand for nature-based experiences. This study determined suitable ecotourism locations using the Analytic Hierarchy Process (AHP) within the Geographic Information Systems (GIS) framework in an area with a typical Mediterranean climate. All data used for analysis were open resources. Thirteen criteria were considered to determine suitable areas, while restricted areas were identified based on a literature review and expert opinions. Findings determine that 65.01% of the total areas are unsuitable for ecotourism, 20.28% are moderately suitable, and 14.71% are highly suitable. Areas near forested lands and open water bodies were found to be the most suitable regions, while the distribution of the most favourable places for ecotourism varied by district across the province. The study provides a fundamental framework as a benchmark for ecotourism planning in similar regions and offers valuable information for future sustainable tourism development initiatives.
