Yayın Assessment of Ibn Haldun’s model for sustainability using structural equation modelling(International Association for Business and Society (IABS), 2020) Kuşakcı, Ali Osman; Kuşakcı, Sümeyye; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüThis work firstly aims to develop a sustainability model based on Ibn Haldun’s teaching of sustainability. Religious coloring refers to the spirituality, which is re-discovered in modern ages and transferred to the workplace. Spirituality stimulates virtuousness at personal and organizational level, which in turn generates managerial sustainability meaning the lifespan of a company. While personal virtuousness refers social ethics, organizational level virtuousness could be considered as Corporate Social Responsibility. Secondly, it attempts to evaluate the relevance of Ibn Haldun’s approach to contemporary business organizations. In order to demonstrate the relationship between spirituality, virtuousness, CSR, and sustainability; data collected from Corporate Knights’ Global 100 companies were analyzed using structural equation modelling. According to the results, while workplace spirituality leads to ethical conduct and higher CSR/CS score, the relationship between spirituality or CSR/CS and financial performance is not significant. However, it seems that higher lifespan of business enterprises is related to their CSR/CS score.Yayın Biyodizel yakıtlar için çok amaçlı sürdürülebilir tedarik zinciri ağ tasarımı(Uludağ Üniversitesi Endüstri Mühendisliği Bölümü ve Lojistik Derneği (LODER), 2018) Kuşakcı, Ali Osman; Kuşakcı, Ali Osman; Karakoç, Enis Barış; Ayvaz, Berk; Kuşakcı, Ali Osman; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüDünyada tüketilmekte olan enerjinin büyük çoğunluğu yenilenemez enerji kaynaklarından olan fosil yakıtlardan elde edilmektedir. Araştırmalara göre dünyadaki mevcut petrol rezervleri yaklaşık 51 yıllık tüketimi karşılayabilmektedir. Biyodizel, fosil yakıtlar için olabilecek en iyi ikame yakıt türü olmasından dolayı en çok kullanılan sıvı biyoyakıtlardandır. Biyoyakıtların üretilmesi için maliyet etkin tedarik zinciri tasarlanması gerekmektedir. Bu çalışmada sürdürülebilir biyodizel tedarik zinciri ağ tasarımı için maliyet minimizasyonu ve çevresel etki optimizasyonu olmak üzere çok amaçlı, sürdürülebilir bir doğrusal programlama modeli geliştirilecektir. Birinci amaç olan maliyet minimizasyonu literatürden yararlanılarak rahatlıkla modellenebilmekte ve çözülebilmektedir. Çevresel etki verileri literatürde çok net bir şekilde belirtilmediği için Uluslarası Standart Örgütü’nün (ISO) geliştirdiği ISO14000 serisi genel çerçeve olarak kabul edilmiştir.Çevresel etki optimizasyonunda; insan sağlığı, ekosistem çeşitliliği ve kaynak kullanılabilirliği ağırlıklandırma yönteminin yardımıyla hesaplamalar yapılmaktadır. Önerilen model; optimum yer, biyorafineride kullanılacak uygun teknoloji, malzeme akışı ve farklı dönemlerdeki üretim planlamalarını içeren Türkiye’de yapılacak olan gerçek bir uygulama olma özelliği göstermektedir.Yayın Profiling consumers' decision-making styles: The case of environmental conscious consumers in Basaksehir, Istanbul(Bandırma Onyedi Eylül Üniversitesi, 2019) Kuşakcı, Ali Osman; Topaloğlu, Kürşat; Kifo, Nour; Yönetim Bilimleri Fakültesi, İşletme BölümüEvery person has differences from others through personality, lifestyle, economic wealth, and their interest. Hence these differences affect their decisions. This research provides a clear look for antecedent studies on consumer decision-making styles (DMS), connects the findings of those studies with today's consumers, and determine a new dimension of the consumers' DMS that affected by new consumer trends, which is thriving by environmental awareness of consumers. Where, less plastic usage and more green products are consumed by environmentally friendly consumers. The research starts with a brief summary of consumers' DMS dimensions, explains the need for the new dimension, clarifies consumers DMS of people that live in Başakşehir, Istanbul, and make suggestions for firm managers, marketers and the future researches. Lastly, results show that six out of eight factors suggested by Sproles and Kendall, [1986], are validated by the research. Whereas, two of the factors are not confirmed, and a new dimension has determined, which is named as “environmentally conscious consumer".Yayın Performance measurement of composite textile industries in Pakistan using data envelopment analysis(2018) Kuşakcı, Ali Osman; Jasmin, Mariam; Bushera, İbrahim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study aims at evaluating and measuring the relative technical efficiency of Pakistan’s textile industry vertically integrated composite firms using Data Envelopment Analysis under the assumption of variable returns to scale (VRS). The data used for this study is collected from the firm’s official website and the Karachi Stock Exchange. This output oriented study covers 29 firms for the period of 2014-2016 employing three homogeneous inputs and outputs. Current asset, production cost and administration cost of the firms are used as inputs elements, gross profit, and total sales and net income compromised the output constituent. In addition to evaluating technical efficiency, this paper examines variations among efficient and inefficient firms. Our findings indicate that, only 17% percent of the firms are scale efficient while 35% of the firms are technically efficient with a mean value of 0.731. Our analysis also indicates an average of 0.572 technical efficiency from constant returns to scale DEA, an average of 0.731 of technical efficiency from variable returns to scale DEA, and an average of 0.805 Scale efficiency. Accordingly, this study confirmed the existence of scale and technical efficiency difference between the firms of the same industry. Though the determinant and factors of efficiency difference among firms is not examined in this study, we recommend that inefficient firms need to enhance their scale size and perk up their managerial practices to enhance their overall efficiency.Yayın Country selection for energy company’s new branch using fuzzy topsis(Yıldız Teknik Üniversitesi, 2019) Kuşakcı, Ali Osman; Chlyeh, Douina; Elaiche, Aicha; Yönetim Bilimleri Fakültesi, İşletme BölümüSolar energy is regarded as one of the most important and promising technologies in the field of renewable energies. Turkey has been one of the first countries to adopt solar energy and harness it in the last two decades. Many Turkish companies especially holdings started to invest in North Africa, either by expanding their operations there or through opening new branches and making alliances with the other countries concerned. This paper aims to identify the best North African country for a specific Turkish company to open a solar energy branch. The process involved Fuzzy Topsis multi-criteria decision making where criteria for selection of one of the countries has been collected from experts, and three decision makers have been chosen to rate the criteria in terms of each alternative countries. Fuzzy topsis analysis was chosen because of the level of the uncertainty in this case study. Regardless of the data available concerning each criterion for all the alternative countries, there is still a certain level of ambiguity to overcome. The results of this study suggested that Algeria would be the best choice for this Turkish company to open up a new branch. The second best fitting country would be Egypt followed by Libya. While Morocco and Tunisia had the lowest ranking.Yayın Efficiency analysis of major airlines: Exploring the operational performance determinants in aviation(Springer, 2024) Yalçın, Kübra Çınar; Kuşakcı, Ali Osman; Tatoğlu, EkremThis paper evaluates the performances and dynamics of productivity changes of 38 airlines from different regions of the world between 2015 and 2019, assessing the effects of business model, alliance membership, the economic development level of the home country, and size on the operational performance of the airlines. In this regard, first, constant returns to scale (CRS) and variable returns to scale (VRS) input-oriented data envelopment analysis (DEA) models with three inputs and two outputs are implemented. The input-oriented CRS model super-efficiency DEA is also used to discriminate between efficient airlines. The Malmquist Productivity Index (MPI) estimates efficiency dynamics across time. Further, the determinants of operational efficiencies are assessed by applying Mann-Whitney rank-sum tests. The analysis results show that most airlines suffer from scale inefficiency. MPI signifies productivity deterioration in airlines’ performance. It is found that low-cost carriers (LCC) have performed better than full-service carriers and alliance member airlines are less efficient than non-member airlines. Additionally, developed country airlines show better performance than their emerging country counterparts. Lastly, the size of airlines measured in available seat kilometers (ASK) is found to have no statistically significant effect on performance.Yayın End-of-life aircraft : The example of Turkish civil aviation industry(Ankara Üniversitesi, 2020) Kuşakcı, Ali Osman; Taş, S.; Elaiche, Aicha; Yönetim Bilimleri Fakültesi, İşletme Bölümü[No Abstract Available]
