Article Citation - Scopus: 3Advertising Ethics: a Field Study on Turkish Consumers(2007) Özdemir, Handan; Ergin, E.A.; Ozdemir, H.; Halkla İlişkiler ve ReklamcılıkThis study examines whether use of deception in ads, cultural stereotyping, sexual stereotyping, and emotional exploitation factors have an influence on the Turkish consumers. Specifically, the aim is to discover whether each of these four factors have any impact on the consumers ' recall of the ad and subsequent purchasing decisions. The results of this study should help foreign and domestic advertising agencies and their clients, already existing in or planning to enter the Turkish market, in understanding the Turkish consumers better.Article Citation - WoS: 1Citation - Scopus: 1Student Participation in Bologna Process: a Case Study From Turkey(Fac Teacher Education, 2014) Kahraman, Zerrin Ezgi; Kahraman, Z. Ezgi; Sakarya, Arif Orçun; Sakarya, A. Orcun; Orçun Sakarya, A.; Şehir ve Bölge Planlama; İşletmeBologna Process studies in Cankaya University's Interior Architecture Department (INAR), Turkey have been initiated in 2008. The goal of this study is to explore students' perceptions about the new programme outcomes framed with the Turkish Higher Education Qualifications Framework and to provide a set of guidelines for the Bologna Process to be implemented. A questionnaire including semi-structured questions is conducted in the data collection process. Content analysis method is used in order to examine students' perceptual outcomes. The findings of the study display that students' perceptions underline the importance of the acquisition of knowledge, skills and competences in social, economic and managerial dimensions of the professional life. Results also reveal the need of students for the acquisition and use of communicative, collaborative and interdisciplinary aspects of the profession and their expectations on both theoretical and practical contents of INAR courses. Furthermore, this study which mainly followed a student-cantered approach concluded that it is also possible to generalize new programme outcomes through the active participation of students.Article Citation - WoS: 8Citation - Scopus: 6Does Adr Listing Affect the Dynamics of Volatility in Emerging Markets(Charles Univ-prague, 2010) Umutlu, Mehmet; Umutlu, Mehmet; Altay-Salih, Aslihan; Akdeniz, Levent; İşletmeThis paper analyzes the time-series variation in the return volatility of non-US stocks from emerging markets that are cross-listed on US exchanges. Unlike previous studies in the cross-listing literature, return volatility is modeled using conditional heteroscedaslicity models. We find that firms' exposure to risks such as local and global market betas remain unchanged after cross-listing. Moreover, we do not identify notable changes in the dynamics of the volatility of cross-listed stocks after cross-listing except for leverage effects. We further show that the mean level of conditional variance is not affected after cross-listing. Thus, our results provide counter-evidence to the belief that foreign investor participation drives volatility upward.Article Citation - WoS: 16Citation - Scopus: 13Wavelet Transform and Artificial Neutral Network for the Quantitative Resolution of Ternary Mixtures(Revista Chimie Srl, 2006) Dinc, Erdal; Baleanu, Dumitru; Baleanu, Dumitru; Tas, Aysegul; MatematikTwo different approaches continuous wavelet transform (CWT) and artificial neural network (ANN) were successfully applied to the quantitative resolution of ternary mixtures of paracetamol (PAR), metamizol (MET) and caffeine (CA) having strongly overlapping spectra. First approach is based on the use of CWT signals of the ratio spectra of three active compounds in samples. Various CWT families were tested for the extraction of cardinal information and small noise condition and higher peaks of the original spectra. In this paper, three methods: Mexican hat function (MEX) (a = 70), reverse biorthogonal (RBIO3.5) (a = 100) and biorthogonal (BIOR2.4) (a = 90) were found suitable for determination of three active compounds and their signal analysis. ANN, as a multivariate numerical method, was used for the quantitative resolution of the same ternary mixtures. The performance of CWT and ANN approaches was validated by analyzing the synthetic mixtures of PAR, MET and CA compounds. In addition, the standard addition technique was also used for the same purpose. The experimental results provided by CWT technique were compared with each other and those obtained by ANN method and a coincidence was observed for all the obtained results.Article Citation - Scopus: 7A Research on Corporate Enterprise Resource Planning (Erp) Systems Used for Supermarket Supply Chain Inventory Management in Turkey(EuroJournals, Inc., 2009) Belbaǧ, S.; Tarım, Şule; Çimen, M.; Tarim, S.; Taş, A.; Çankaya Meslek YüksekokuluThe purpose of this study is to draw a detailed picture of the current situation with regard to supply chain inventory planning systems used in the Turkish retail sector. During the study, companies developing enterprise resource planning (ERP) software were contacted and asked questions oriented to reveal the contribution of current enterprise resource planning software in supply chain management and the opportunities they offer to users in terms of inventory planning. Interviews were made using one or more of the interview techniques of electronic mail, telephone or one-to-one interview. Through these interviews, it was attempted to determine the estimation and planning capabilities of the existing ERP software and draw an inventory of the solutions currently offered to users that will meet the varying demands of the companies operating in the retail sector. In addition, a comparison of the ERP products of national and foreign software companies producing solutions with various functionalities for the retail sector is made along with an evaluation in view of enterprise management. © EuroJournals Publishing, Inc. 2009.Conference Object The Effect of Knowledge Economy on Organizational Environments: Do the Governance Mechanisms Differ According To Institutional and Technical Environments(int Business information Management Assoc-ibima, 2009) Sener, Irge; Şener, İrge; İşletmeTechnological developments result in important changes for organizations and their environment. The most remarkable change in the organizational field is the widespread usage of Internet, a new information and communication technology (ICT). The changes depending on Internet, affect organizational structures, since they are designed compatible to the communication needs dependent on the technology. In some cases, however, the communication technologies can be developed in consistence with the organizational structure. This indicates that, when ICTs are taken into consideration, it occurs that there is no clear distinction between technical and institutional organizational environments. The ICTs dependent on Internet is both a legitimacy source for the organizations and an efficiency tool. Accordingly, in this study it is considered that the technical and institutional environments are interpenetrated and different types of governance mechanisms result due to the varying effects of the environmental pressures. Testable propositions are developed for different types of environments.Article Industry 4.0 Readiness of Smes: Active Participants or Silent Audience of the Revolution(Sosyoekonomi Soc, 2023) Sener, Irge; Karapolatgil, Ahmet AnilNowadays, the technological consequences of the Fourth Industrial Revolution affect all organisations. However, the current reactions of SMEs have yet to be explored. For this reason, this study focused on the actual status of SMEs and aimed to determine their readiness and awareness of Industry 4.0 technologies. Semi-structured interviews were conducted with 44 SME managers operating in Ankara, constituting the study sample. Research findings were examined within the scope of 3 main themes determined by content analysis. In this context, it has been concluded that SMEs in the sample have low awareness of Industry 4.0, and their readiness needs to be improved.Article Citation - WoS: 2Citation - Scopus: 9Predicting Financial Failure of the Turkish Banks(World Scientific Publ Co Pte Ltd, 2006) Doganay, M. Mete; Ceylan, Nildag Basak; Aktas, Ramazan; Akta, RamazanBanks are the most important financial institutions in Turkey because other financial institutions are not developed efficiently yet. Turkish banks experienced financial difficulties and a substantial amount of banks failed in the past. This event urged the government to initiate measures to prevent banks from getting into financial difficulties. As a result of these measures, Turkish banking system currently seems to be very attractive for the foreign investors willing to invest in this sector. One of the main concerns of the foreign investors is a possibility of a new banking crisis although it is very remote at this time. The purpose of this study is to develop early warning systems predicting the financial failure at least three years ahead of financial date. A number of multivariate statistical models such as multiple regression, discriminant analysis, logit, probit are used. We found that the most appropriate model is logit. The significant variables obtained from the models explain very well the causes of the bank failures. Our models can be used to assist interested parties to predict the probability of financial failure of Turkish banks.Conference Object Citation - Scopus: 4Robust Principal Component Analysis by Reverse Iterative Linear Programming(Springer Verlag, 2016) Visentin, A.; Prestwich, S.; Armagan Tarim, S.Principal Components Analysis (PCA) is a data analysis technique widely used in dimensionality reduction. It extracts a small number of orthonormal vectors that explain most of the variation in a dataset, which are called the Principal Components. Conventional PCA is sensitive to outliers because it is based on the L2-norm, so to improve robustness several algorithms based on the L1-norm have been introduced in the literature. We present a new algorithm for robust L1- norm PCA that computes components iteratively in reverse, using a new heuristic based on Linear Programming. This solution is focused on finding the projection that minimizes the variance of the projected points. It has only one parameter to tune, making it simple to use. On common benchmarks it performs competitively compared to other methods.

Sustainable supply chains, when managed with the right strategies, will ensure several advantages for all collaborators in the chain. With the increasing consumer awareness, the studies conducted in recent years focus on the environmental and social dimensions as well as the economic factor of sustainability. Sustainability factors; "environmental, economic and social" also known as three pillars of sustainability are considered together in order to increase the benefits offered by the sustainable supply chain. In this study, closed-loop supply chain themed studies that deal with three pillars of sustainability in the literature were examined based on sub-factors. Studies have shown that, Life Cycle Analysis (LCA) methods such as ReCipe, Eco-Indicator 99 and CO2 emission are the approaches used to determine the environmental factors of sustainability. Cost, profit and Net Present Value (NPV) methods are used to measure the economic dimension of sustainability. Job opportunities, losses and Customer Service Level (CSL) are most commonly used as sub-criteria to determine social factors. Accordingly, a sustainable closed-loop supply chain model consisting of seven echelons has been examined. A deterministic mixed integer linear programming model (MILP), which includes the economic dimension of sustainability, has been developed and enclosed with sample solutions. Suggestions for sustainability criteria and improving the proposed model have been made for future studies.
