Öğe The MEREC-AROMAN method for determining sustainable competitiveness levels: A case study for Turkey.(Socio-Economic Planning Sciences, 2023-11-17) Acar, A. Zafer; Kara, Karahan; Yalçın, Galip Cihan; Simic, Vladimir; Konya, Serkan; Pamucar, DraganABSTRACT: Sustainable competitiveness represents a multifaceted phenomenon encompassing economic, environmental, and social dimensions. Macro-level competitiveness strategies are formulated based on the diverse capitals possessed by individual countries, thereby giving rise to variations in the sustainable competitiveness strategies of each country. This research introduces a novel hybrid method called the method based on the removal effects of criteria (MEREC)? alternative ranking order method accounting for two-step normalization (AROMAN) for determining sustainable competitiveness levels. This study aims to assess Turkey’s sustainable competitiveness position vis-` a-vis its border neighbors. Natural capital, resource efficiency and intensity, social capital, intellectual capital and innovation, economic sustainability, and governance efficiency are the Global Sustainable Competitiveness Index (GSCI) indicators. The GSCI indicators are employed as criteria for determining the sustainable competitiveness scores of countries. The findings show that the “resource efficiency and intensity” criterion has the highest level of significance. The sustainable competitiveness level of Turkey to its neighboring countries is elucidated based on the results. Recommendations are formulated for the development of strategies aimed at determining Turkey’s position in the race for sustainable competitiveness. The introduced MERECAROMAN can be utilized to provide rules of thumb for other countries to improve their sustainable competitiveness. This research offers decision support for the formulation of countries’ sustainable competitiveness strategies and policies, fostering awareness in the planning and establishment of regional collaborations among nations.Öğe Identifying the effects of corruption perception on the relationship between international trade and logistics performance in developing countries(Business, Management and Economics Engineering, 2023-05-15) Acar, A. Zafer; Kara, KarahanABSTRACT: Purpose – logistics creates a strategic effect by playing a facilitating role in interna-tional trade, which has a significant impact on the economic performance of countries. Logis-tics performance and corruption play an influential role in determining the trade efficiency levels of developing countries. There are two purposes in this research. First purpose is to determine the international trade efficiency level of developing countries based on logistics performance. The second purpose is to determine the efficiency level of trade based on both logistics performance and corruption levels. Research methodology – output-oriented data envelopment analysis (DEA) has been applied in the research. The research covers the years 2012–2020. The sample area is developing countries. Findings – countries with full efficiency levels in 2012–2020 have been determined according to both logistics performance and corruption scores. Research limitations – the research covers the years 2012–2020. The sample area is develop-ing countries.Practical implications – the reduction of corruption levels in some developing countries is an important factor in increasing the level of international trade efficiency. Originality/Value– this research highlights the role of corruption in the relationship between trade and logistics performance.Öğe A spatial multi-criteria decision-making model for planning new logistic centers in metropolitan areas(Supply Chain Analytics, 2023-03) Acar, A. Zafer; Önden, İsmail; Eldemir, Fahrettin; Çancı, MetinABSTRACT: The logistics center concept has been discussed in the literature for over four decades. Logistics centers simplify the logistics network and have many advantages, such as lower transportation costs, an economy of scale, and integrated service capabilities. We propose a spatial multi-criteria decision-making model for new logistic centers in metropolitan areas. The first focus of the study is identifying the logistic concerns, defining the factors affecting the replacement decisions and determining the weights of the factors in metropolitan areas with many expert opinions. The second focuses on spatial analysis to locate new logistics centers serving urban areas. We present a case study in Istanbul, the most populous metropolis in Europe, to demonstrate the applicability and exhibit efficacy of the method proposed in this study. Outputs of the study pointed out where the convenient places are to locate new logistics centers.Öğe Unsustainable supply chain of sustainable food companies(Journal of Management, Marketing and Logistics, 2022) Acar, A. Zafer; Kaya, AhmetABSTRACT Purpose - This study aims to investigate the sustainable food companies within the scope of sustainable supply chain management (SSCM). It also aims to reveal what are the challenges food companies face in their sustainable supply chains. In addition, it is aimed to show which points should be focused on in sustainable supply chain management. Methodology - For this purpose, sustainability pages on the corporate website of 30 food companies operating in Turkey were analyzed with content analysis by adopting a qualitative research paradigm and an interpretive framework. While analyzing the contents, first of all, it was investigated at which dimensions the food companies attach importance to in the Triple Bottom Line approach. Secondly, the elements that food companies pay attention to while they integrate the supply chain into their sustainability practices were examined. Lastly, it was analyzed in which dimension of the sustainable supply chain management the food companies are located. Findings - The findings of the study indicated that 23 of the food companies were found to be sustainable businesses according to the Triple Bottom Line approach. However, it was demonstrated that the same companies could not provide sustainability in supply chain management. In this sense, it was understood that one of the biggest reasons for this is that companies ignore the concept of “risk management”. Conclusion - As a result, the points that food companies have difficulty in sustainable supply chain management have been revealed. With this study, practical contributions were provided to the companies in terms of enabling them to evaluate themselves on this issue. In addition to this, the study also contributes to the field by building on the studies investigating sustainable supply chain management and providing a different perspective with the investigation of the issue from a TBL approach.Öğe Tüketici motivasyonları ile sosyal medyanın tüketici davranışına etkisinin satın alma niyetine etkisinin hava yolu yolcu taşımacılığında incelemesi(İşletme Araştırmaları Dergisi, 2019) Önen, VahapÖZET: Amaç – Bu çalışma sosyal medya ortamında bilet satın alan yolcuların satın alma öncesi ve sonrası davranışlarının satın alma niyetine etksini ve sosyal medyanın faydacı ve hedonik motivasyonların satın alma öncesi ve sonrası tüketici davranışlarına etkilerinin belirlenmesi amacıyla yapılmıştır. Yöntem – Çalışmada hedonik ve faydacı motivasyon kapsamında, soyal medya ortamınının satın alama öncesi ve sonrası tüketici davranışınına etkisine yönelik ve satın alma niyetinin belirlenmesi kapsamında 5’li Likert tipi ölçeğiyle dört ayrı ölçek kullanılarak yüz yüze anket yöntemi uygulanmıştır. Ölçeklerin geçerliliği ve araştırma modelinin testine yönelik açıklayıcı faktör, güvenirlilik ve doğrulsal regresyon analiz yöntemleri kullanılmıştır. Bulgular – Yapılan çalışma sonucunda sosyal medya ortamında bilet satın alan tüketicilerin satın alma öncesi davranışları ile satın alma sonrası davranışlarının soysal medyadan etkilendikleri ve bu etkilerin de havayolu bilet satın alma eğilimini anlamlı, pozitif ve güçlü yönde etkiledikleri görülmüştür. Ayrıca çalışmada, havayolu sosyal medya ortamlarının faydacı motivasyon özelliğinin tüketiciler tarafından daha belirgin algılandığı görülerek, bu yönde yapılan motivasyonların sosyal medya ortamında bilet satın alan tüketiclerin satın alma öncesi satın alma sonrası davranışlarında anlamlı ve pozitif yönde desteklediği buna karşın tüketicilerin sosyal medya ortamlarının hedonik olma özelliğinin satın alma öncesi ve satın alma sonrası tüketici davranışlarına bir etkisi olmadığı belirlenmiştir. Tartışma – Havayolu firmalarının sosyal medya ortamlarında gerek satın alma öncesinde gerekse de satın alma sonrasında tüketcilerle olan etkileşimini devam ettirmesi ve daha da geliştirmesi, satın alma niyetine etki edebilecek e-wom, müşteri deneyimi, marka sadakati gibi diğer faktörleri de dikkate alınması gerekmektedir. Havayolu firmaları soyla medya platormlarının hedonik ve faydacı motivasyon özelliklerini ayırt edici şekilde özelliklerinin yeniden tasarlanmaları, değişikliklerin yapılması ilave olarak tüketicilerin satın alma öncesi ve sonrası davranışlarına etki eden diğer faktörler ve motivasyonlar açısından sosyal medya tasarımlarını ele almalıdırlar.
