Perceptions on the impact of logistic villages on local entrepreneurship potential: The case of Hopa
(Ahmet Arif Eren, 2025) Sözbilir, Fikret
Logistics villages play a crucial role in development due to their macro and microeconomic contributions to the regions where they are established. To establish logistic villages, a large area of land and infrastructure in terms of transportation modes such as maritime line, airline, highway and railway must be sufficient. Logistics villages also provide important opportunities in terms of entrepreneurial activities and include facilities that can increase entrepreneurship potential. The aim of this study is to examine the impact of the opportunities provided by logistic villages on entrepreneurship potential and to make recommendations depending on the results obtained. Within the scope of the study, data was collected through a survey from managers, employees in institutions and organizations operating in the fields of logistics, customs and foreign trade in Hopa district, and expert academicians. A total of 110 people participated in the study, which was determined as the main population of 200 people, and the return rate of the surveys was 55 %. In the correlation analysis conducted, no significant relationship was found between the deficiencies dimension for the logistic village and the strategic factors dimension of entrepreneurship potential, on the other hand, it was seen that all other factors had significant relationships between them. The regression analysis results also determined that the advantages dimension for the logistics village had a significant and positive impact on the entrepreneurship potential (general) and its sub-dimensions ‘strategic factors’, ‘marketing and distribution’ and ‘cooperation and synergy’. However, it was understood that the disadvantages dimension for the logistics village did not have a significant impact on the entrepreneurship potential (general) and its sub-dimensions.
Döviz kuru dalgalanmalarının sınır ticaretine ve bölgesel kalkınmaya etkisi: Artvin ili örneği
(Ömer Halisdemir Üniversitesi, 2025) Berberoğlu, Murat; Şimşek, Orhan; Adalı, Zafer; Şakı, Mert
Bu çalışma, Türk lirası (TRY) ile Gürcistan larisi (GEL) arasındaki döviz kuru dalgalanmalarının Artvin ilinin Hopa, Kemalpaşa ve Arhavi ilçelerindeki sınır ticareti, sabit sermaye yatırımları ve bölgesel kalkınma üzerindeki etkilerini analiz etmeyi amaçlamaktadır. Araştırmada nicel yöntem benimsenmiş ve söz konusu ilçelerde faaliyet gösteren işletmelerden anket yoluyla veri toplanmıştır. Çalışma kapsamında, 132 işletmeden elde edilen geçerli anket verisi, TRY’nin göreli olarak güçlü olduğu dönem, TRY’nin değer kaybettiği dönem ve TRY’nin yeniden değer kazandığı dönem olmak üzere üç farklı zaman dilimine ayrılarak incelenmiştir. Veriler üzerinde tanımlayıcı istatistikler hesaplanmış ve ilçeler arası farklılıkları belirlemek amacıyla parametrik olmayan fark testleri (Kruskal-Wallis ve Mann–Whitney U) uygulanmıştır. Analiz sonuçları, döviz kuru dalgalanmalarının işletmelerin satış hacmini ve kârlılığını düşürürken maliyetlerini ve borçlanma ihtiyacını artırdığını göstermektedir. Kur oynaklığının yarattığı belirsizlik ortamında sabit sermaye ve çalışma sermayesi yatırımlarında da azalma gözlenmiştir. İlçe bazında, Kemalpaşa’daki işletmelerin döviz kuru değişimlerinden diğer ilçelere kıyasla daha olumsuz etkilendiği tespit edilmiştir. Anket bulguları ayrıca işletmelerin çoğunun Türk lirasının geleceğine dair beklentilerinin olumsuz olduğunu, büyük bir kısmının TRY’nin değer kaybının süreceğini öngördüğünü ortaya koymaktadır. Bulgular genel olarak, döviz kuru istikrarının sınır ticareti ve yatırım kararlarının sürdürülebilirliği açısından kritik önem taşıdığını vurgulamaktadır.
Tarımda dijitalleşme süreci: Lisanslı depoculuk, ELÜS ve TÜRİB üzerine bir alan araştırması
(Türk Kooperatifçilik Kurumu, 2025) Berberoğlu, Murat; Kızılkan, Çiçek
Tarım sektörü, teknolojik gelişmelerin etkisiyle üretimden pazarlamaya, depolamadan finansmana kadar tüm değer zincirinde dijital dönüşüm sürecine girmiştir. Türkiye’de bu dönüşümün kurumsal çerçevesini Lisanslı Depoculuk (LD), Elektronik Ürün Senedi (ELÜS) ve Türkiye Ürün İhtisas Borsası (TÜRİB) oluşturmaktadır. Çalışmanın amacı, üreticilerin bu sistemlere ilişkin bilgi düzeylerini, kullanım niyetlerini ve kullanılmama nedenlerini incelemektir. Doğu Karadeniz Bölgesi’nde (Giresun, Ordu, Trabzon, Samsun) faaliyet gösteren 403 fındık üreticisinden anket yoluyla veri toplanmış; elde edilen veriler ANOVA, bağımsız örneklem t-testi ve Ki-Kare testi ile analiz edilmiştir. Bulgular, katılımcıların yarısından fazlasının LD hakkında, yaklaşık %70’inin ise ELÜS ve TÜRİB hakkında düşük bilgi düzeyine sahip olduğunu göstermektedir. Yaş ve tarımsal tecrübe arttıkça LD ve ELÜS bilgi düzeyleri anlamlı biçimde yükselmekte; özellikle 56 yaş üzeri ve 21 yılın üzerinde tecrübeye sahip üreticiler daha yüksek bilgiye sahiptir. Cinsiyet açısından yalnızca LD’de anlamlı fark bulunmuş, kadınların bilgi düzeyi erkeklerden yüksek çıkmıştır. Ayrıca, bilgi düzeyi daha yüksek olan üreticilerin gelecekte sistemi kullanmaya daha eğilimli oldukları belirlenmiştir. LD ve ELÜS kullanım düşüklüğünün başlıca nedeni bölgede lisanslı depo bulunmaması iken, TÜRİB için temel neden yetersiz bilgilendirmedir. Katılımcıların çoğunluğu gelecekte de LD ve ELÜS’ü kullanmaya istekli değildir; TÜRİB için ise eğilim yarı yarıya dağılmaktadır. Kullanım dışı kalma nedenleri ile yaş ve tarımsal tecrübe arasında istatistiksel olarak anlamlı bir ilişki saptanmamış, ancak bazı gruplarda örtük ilişkiler olabileceği değerlendirilmiştir. Sonuçlar, literatürde vurgulanan bilgi eksikliği, geleneksel pazarlama alışkanlıkları ve düşük finansal okuryazarlık bulgularıyla örtüşmektedir.

(Scientific Oasis, 2025) Aytekin, Ahmet; İstanbullu, Beril; Kara, Kübra
This study aims to determine the main problems of Certified Public Accountants (CPAs) and the sub-problems under them and to develop solution proposals for these problems. In this context, evaluations will be obtained regarding the problems of CPAs and the solutions to these problems via the q-rung orthopair fuzzy Delphi technique. The study differentiates itself from the literature and reveals its originality with the revealing of current problems of CPAs, the development of solution proposals for these problems, and the employed methodological approach. Based on literature and expert opinions, 53 problems and 14 solution suggestions were identified. It was found that the 28 problems were critical, and the nine solution suggestions could provide a meaningful solution. In addition, the findings showed that the most critical problems were the stress of the profession, heavy workload, and frequently changing legislation. The most critical solution proposals were to transfer the legal obligations that coincide with the financial holiday period to the next month by the Ministry of Finance, to prepare the legislation related to accounting in coordination with chambers and members of the accounting profession, and to simplify tax declarations.
The long-run relationship between labour force participation rate and unemployment rate for Türkiye: COVID-19 matters
(Routledge, 2025) Sivri, Uğur
This article investigates the long-run relationship between the labour force participation rate and the unemployment rate for Türkiye. Using Johansen cointegration methodology, both aggregate and gender-disaggregate data are analysed. Having observed the substantial effects of the COVID-19 shock, monthly data that cover 2005M1-2024M12 period are split into two subperiods: Pre-COVID-19 period (2005M1-2019M11) and post-COVID-19 period (2021M09-2024M12). Compared to pre-COVID-19 period, findings have changed in three important ways in post-COVID-19 period. Firstly, the results of aggregate and gender-disaggregate data completely agree with each other in terms of the existence of the cointegration relationship. Secondly, the cointegration relationship is confirmed for all groups. Thirdly, estimated cointegration vectors provide consistent support for the Discouraged Worker hypothesis.

(Nexora Academic Press, 2025) Korucuk, Selçuk; Aytekin, Ahmet
Environmental practices have been incorporated into business models and procedures in today's competitive climate, and they are now significant challenges that require attention. Businesses have undergone several changes as a result of these practices, including concerns about preserving a habitable environment for future generations and guaranteeing energy efficiency with sustainable production. To the extent that green manufacturing practices have been included into business strategies and used to inform future planning. In this context, green production practices have emerged as a crucial factor that requires careful attention from businesses. Nowadays, green production is a crucial tool for manufacturing businesses. The study investigated what motivates manufacturing companies to engage in green production practices. The goal was to weight the characteristics that were identified as driving businesses to engage in green manufacturing operations. To do this, the identified criteria were weighted using one of the multi-criteria decision analysis techniques, direct rating. The results of the application showed that "support from top management," "increasing demand for green products," and "increasing public pressure" were the main drivers of manufacturing companies' transition to green production practices.
The impact of social capital on innovative behaviour as a reflection of creativity: The case of education sector
(Vilnius Gediminas Technical University, 2025) Sözbilir, Fikret; Kaya, Sıdıka
Social capital enables sharing, trust, solidarity, proper norms and respectful behav-iours, and organisational participative management. Employee innovative behaviour is vital for organisations as it provides a competitive advantage. This study aims to determine the impact of social capital and its sub-dimensions, friendly acceptance, norms of behaviour, trusting/rec-iprocity, and governance on innovative behaviour and its sub-dimensions, participative lead-ership, external work contacts, and innovative output on innovative behaviour. The data were gathered from 264 school administrators and teachers through a questionnaire. The SPSS Statistics 25.0 program was used to test the research hypotheses. Reliability and validity analysis results are sufficient. The results showed that social capital (overall) and its all-sub-dimensions, except trusting/reciprocity, significantly and positively impact innovative behaviour. However, most of the sub-dimensions of social capital have no significant impact on the sub-dimen-sions of innovative behaviour.

Assessing the convergence of cropland ecological balance: A panel data analysis of 13 major agricultural countries
(Bilingual Publishing Group, 2025) Şimşek, Orhan; Güler, İlkay; Özbek, Sefa; Naimoğlu, Mustafa; Adalı, Zafer
This study investigates the convergence hypothesis and stochastic dynamics of agricultural land use and ecological balance across 13 major agricultural countries from 1992 to 2022. The study's concentrated samples are Russia, the United States, the Netherlands, Brazil, Germany, China, France, Spain, Italy, Canada, Belgium, Indonesia, and India. The research uncovers notable variations in ecological balance by utilizing a comprehensive set of advanced panel unit root tests (Panel CIPS, CADF, Panel-LM, Panel-KPSS, and Bahmani-Oskooee et al.’s Panel KPSS Unit Root Test). The findings highlight significant improvements in Canada, contrasting with declines in the Netherlands, France, Germany, and the United States. The results indicate convergence in ecological balance among these countries, suggesting that agricultural practices are progressively aligning with sustainability objectives. The considered countries can determine and enact joint and collective policy actions addressing cropland sustainability. However, the univariate outcome also shows that the cropland ecological balance of Germany, China, France, Indonesia, and India does contain a unit root and stationary which means the presence of the constant-mean. The univariate actions from the mentioned governments will not promote persistent impact. Therefore, joint actions determined by the countries considered are recommended for the mentioned countries. However, the rest of the countries also enact local policies. The insights gained are critical for informing global sustainability strategies and aiding policymakers in developing effective measures to enhance agricultural practices and mitigate environmental impacts. This research provides a data-driven foundation for optimizing agricultural sustainability and supports international efforts to achieve long-term ecological stability.
Proposing appropriate strategies for domestic tourism promotion in developing country by fuzzy fermatean MCDM approach
(Research Expansion Alliance (REA), 2025) Bakary, Stephen Jeuma; Bouraima, Mouhamed Bayane; Aytekin, Ahmet; Ntoh-Gyan, Kwame
Promoting tourism is essential for the success of any destination. Nevertheless, despite the Tanzanian government’s various initiatives to boost the sector, significant challenges remain that obstruct its promotion. This study aims to identify challenges and strategies to promote the tourism sector. We introduce a novel hybrid method called Stepwise Weight Assessment Ratio Analysis (SWARA) method within a Fermatean Fuzzy (FF) environment and Alternative Ranking Order Method Accounting for two-step Normalization (AROMAN). FF-SWARA determines the relative importance of criteria, and AROMAN is employed to rank the strategies. Through sensitivity and comparative analyses, the study validates the effectiveness of this methodology, revealing that the primary obstacles to tourism promotion stem from a lack of domestic tourism development and marketing policy and strategy and the lack of domestic tourism promotion marketing packages. Additionally, the analysis identifies investing in domestic tourism infrastructure and increasing the visibility of tourist attractions and events as the most impactful strategies for overcoming these challenges. This study has significant practical implications for Tanzania's tourism sector by providing a strategic framework to address key challenges hindering domestic tourism growth.
Corporate sustainability strategy selection for a metropolitan municipality using a trapezoidal interval type-2 fuzzy SWARA–COPRAS framework
(Springer Science and Business Media Deutschland GmbH, 2023) Toptancı, Şura; Gündoğdu, Hakan Gökhan; Korucuk, Selçuk; Aytekin, Ahmet; Stević, Željko
Local governments are willing to use their activities and resources in accordance with the changing and transforming conditions. Especially with the increasing importance of sustainability, economic, social, and environmental strategies are redefining. Thus, a sustainable corporate governance model that includes a systematic and analytical approach should be used to solve the decision-making problem of local governments regarding changing corporate and environmental sustainability strategies. In particular, new measurement methods are required to define the sustainability outputs/strategies of local governments. In this context, it is clear that there is a need for a more holistic approach that focuses not only on the immediate effects at the local government level but also on the positive effects on the entire system. While the study fills this gap, it also evaluates the long-term and sustainable impacts of the organization. The study also contributes to a methodological framework that can help advance future research on the practice of monitoring sustainable development by local governments. This study aims to determine the best corporate sustainability strategy by evaluating environmental sustainability from the perspective of local governments. For this purpose, the criteria were evaluated using trapezoidal interval type-2 fuzzy SWARA, and the alternatives were ranked through trapezoidal interval type-2 fuzzy COPRAS methods. The findings show that net-zero targets and sustainable production are more crucial criteria. Additionally, it has been determined that social and environmental strategies have priority in the selection of alternative criteria related to corporate sustainability. The main finding of this study is that local governments include responsible production criteria in their priority policies. The results obtained contribute to the literature on measuring sustainable development outcomes in local government organizations and identify strategies and improvement opportunities that can lead to better practices.
The barriers related to smart manufacturing systems and an application for the selection of innovation management Model: The case of Samsun province
(Springer International Publishing, 2023) Aytekin, Ahmet; Korucuk, Selçuk; Karamaşa, Çağlar
More productive processes and innovation management have gained popularity due to technological advancements enabling flexible manufacturing, cost-effectiveness, and business process optimization. In the information age, Industry 4.0 has strengthened the relevance of smart systems, and the smart concept is emphasized for innovative production processes. In other words, integrated innovative automation and digitalized solutions provide businesses with a competitive advantage. Conse-quently, smart manufacturing technologies that enable effective and quick production processes can be regarded as key elements for businesses. However, businesses face many barriers when transitioning to and adopting smart manufacturing systems. To increase production and efficiency, businesses must remove or reduce barriers to the lowest possible level. However, in both service and manufacturing organizations, innovation management and innovation management models are critical indicators for enhancing competitiveness and providing a cost advantage. This is also beneficial for technology and smart management practices. In this context, this chapter aims to determine the importance of barriers to smart manufacturing systems in plastic sector companies operating in Samsun and select the best innovation management model. While the Neutrosophic AHP method was used to weigh the criteria, the Neutro-sophic MARCOS method was utilized to rank the alternatives consisting of linear, balanced, interactive, and learning-integrated system models. According to the study, the most significant barriers to smart production systems are “Smart manufacturing system expenses” and “Insufficient technical infrastructure.” The integrated learning systems model was chosen as the best model for innovation management.
Examining the effects of the Russia-Ukraine conflict on global supply chains
(IGI Global, 2023) Toygar, Arda; Yıldırım, Umut
Conflicts cause significant losses of life and property, create environmental and socio-cultural changes, and lead to significant disruptions in global supply chains. The Russia-Ukraine conflict, occurring on Ukrainian territory, is still ongoing and its consequences are uncertain. This bottleneck in global food and energy supply, large increases in the costs of basic logistics services, such as international transportation and warehousing, come to the fore as the first consequences of the conflict. These developments prevent countries in many distinct parts of the world from reaching vital resources, such as food and energy. Therefore, this study aims to evaluate the effects of the Russia-Ukraine conflict on global supply chains. In this context, the relevant literature, sectoral publications, and reports from international authorities related to global supply chains were examined in a conceptual framework. The results of the study suggest that the conflict poses significant problems that will adversely affect global supply chains.
Evaluating and selecting sustainable logistics service providers for medical waste disposal treatment in the healthcare industry
(Elsevier Ltd, 2023) Görçün, Ömer Faruk; Aytekin, Ahmet; Korucuk, Selçuk; Tirkolaee, Erfan Babaee
Health institutes are structurally growing depending on the population increase and escalating demands for health services. As a negative result, the health industry produces more healthcare waste daily. Its efforts and resources cannot be sufficient to dispose of such medical wastes as the quantity and variety continue to increase. Therefore, developing solution partnership relations with logistics service providers specialized in collecting, storing, and disposing healthcare waste may be a beneficial and fruitful step for solving this problem. However, the evaluation and selection of service suppliers for healthcare waste disposal may not always result in success. Hence, the present work develops a robust integrated methodology on the basis of Step-wise Weight Assessment Ratio Analysis (SWARA) and COmplex PRoportional ASsessment (COPRAS) techniques based on Interval-Valued Fermatean Fuzzy Sets (IVFFSs) for healthcare decision-makers to make more rational and optimal decisions concerning service supplier selection. The proposed model based on the IVFFSs can also overcome incredibly complicated uncertainties in the assessment processes. A large-scale international hospital chain in Turkey is investigated using the developed methodology to find reasonable and logical solutions to assess and select the best Medical Waste Disposal and Logistics (MWDL) firm. It is revealed that the most important criterion is “Storage Conditions” where “Republic Services, Inc” is the most successful supplier of MWDL. Finally, theoretical and practical implications are discussed in detail in order to provide useful managerial insights and decision aids to assist in improving the sustainability of healthcare industry.
Fresh food supplier selection for global retail chains via bipolar neutrosophic methodology
(Elsevier Ltd, 2023) Görçün, Ömer Faruk; Aytekin, Ahmet; Korucuk, Selçuk
Due to increases in world population, rapid urbanization, increasing environmental pollution, and poorly managed food supply chains (FSCs), supplying clean and reliable agri-food has become more critical. Furthermore, increasing concerns of the urban population on healthy and balanced nutrition have increased their demand for fresh foods (FFs). Also, the retail industry has become the leading sector responding to almost all requirements of individuals, including FFs. Heightened awareness of individuals on health, reliability, and quality forces retail chains to provide more qualified, sustainable, and reliable FFs for their customers. Retail chains try to construct and manage well-structured global fresh food supply chains (FFSCs) to respond to customers' needs satisfactorily. Thus, selecting logistics service providers performing FF logistics operations (i.e., cold transportation, warehousing, and other logistics activities) from farms to retailers is essential for reliable and sustainable FFSCs. Because FFSCs are pretty sensitive, and minor mistakes or delinquency may cause severe costs. Global retail chains, in particular, only focus on meeting short-term demand and not on a sustainable fresh food supplier selection; fresh food suppliers are essential to determine sustainability performance. In this context, a more holistic approach is needed, focusing not only on the global retail chain level's direct impacts but also on the positive impacts at the overall system level. While this study fills a gap, it also assesses the long-term and lasting impact of choosing a fresh food supplier. In addition, the impacts of logistics service providers on FFSCs' overall performance have not been addressed adequately in the relevant literature. This work aims to analyze the factors identified by the extended form of the Delphi method developed in the present article, influencing the selection of logistics service providers producing logistics services for fresh fruits and vegetables with the BN-VIKOR procedure. The paper's main significant finding is that the logistics firms' service capacity is the determinative and most influential factor. The current study provides insights and beneficial road maps to the practitioners and decision-makers in retailing industry to structure FFSCs. The results contribute to the literature on criteria for selecting sustainable fresh food suppliers in global retail chains and identify strategies and improvement opportunities that can lead to improvement in practice.
Agile supply chain management based on critical success factors and most ideal risk reduction strategy in the era of industry 4.0: Application to plastic industry
(Springer, 2023) Korucuk, Selçuk; Tirkolaee, Erfan Babaee; Aytekin, Ahmet; Karabasevic, Darjan; Karamaşa, Çağlar
In the global trade economy, the degree of competition and differentiation among organizations working in the sector of Supply Chain Management (SCM) is expanding gradually. For companies, SCM operations are becoming more important than manufacturing, sales, and marketing activities, and new ways and methods are preferred for efficiency and performance. The agility (or agility phenomenon) is one of the applications that aids effective SCM operations in this context. Agile Supply Chain Management (ASCM) and the emergence of Industry 4.0 practices, in addition to offering a cost advantage and business performance improvement, are crucial in providing flexibility to companies and ensuring their survival in the era of Industry 4.0. Meanwhile, companies aim to deal with uncertainty and implement various risk-reduction strategies as part of effective SCM. In this context, the study lists the critical success factors of ASCM and selects the most appropriate risk reduction strategy for companies that manufacture and market rubber and plastic products with a corporate identity and conduct import and export business in Istanbul. For this purpose, the criteria and alternatives specified in accordance with the literature review and experts’ opinions are examined using Bipolar Neutrosophic Stepwise Weight Assessment Ratio Analysis (BN-SWARA) and Bipolar Neutrosophic Technique for Order of Preference by Similarity to Ideal Solution (BN-TOPSIS) methods. The ranking results are then discussed in line with the practical implications to provide managerial insights and decision aids. Finally, the main limitations are expressed in order to delineate useful future research directions.
