Öğe The effect of COVID-19 pandemic on university education: Adoption of e-learning and testing the technology acceptance model(Korean Educational Developmental Inst, 2022) Akin, Bahar; Boztoprak, Hasan; Guzey, Yildiz Yilmaz; Suslu, MuratThis study aims to investigate the factors affecting the acceptance of e-learning among university students, especially during the COVID-19 pandemic, and to reveal the factors affecting the reasons for students to use e-learning systems. We adopted the Technology Acceptance Model (TAM) to understand better the adoption of e-learning systems by university students. We gathered data from 716 university students who received distance education during the pandemic and used SPSS 22.0, AMOS 22.0 and SmartPLS 3.3 software to perform statistical analyses. The findings indicate that compatibility is related to perceived ease of use and perceived usefulness. Moreover, attitude is influenced by perceived ease of use and perceived usefulness. The results reveal the importance of perceived ease of use, perceived usefulness, self-learning necessity, and compatibility on intention to use.Öğe Industrial Drivers of Co-opetition Among Organizations: A Sector-Based Research Within the Context of Population Ecology Approach(Springer International Publishing Ag, 2020) Boztoprak, Hasan; Mutlu, Nusret Erhan; Suslu, Murat; Guzey, Yildiz YilmazCo-opetition is the term which defines a hybrid behavior comprising competition and cooperation concurrently. Co-opetition strategy extends the traditional rules of competition and collaboration strategies. In this paper, we aimed to explain the co-opetition relationship between rivals by using the assumptions of the population ecology approach. We have collected data from two industries having different levels of entrant and exiting rates to compare population-originated drivers of co-opetitive relationships. We have evaluated generally the effect of entering and exiting of rivals in the industry on co-opetition tendency of firms in both industries. To embody the assumptions of population ecology approach, we have used age, size, and niche width of organizations. By compassion two industries we found that there is no difference among industries for getting co-opetition against entering and exiting of rivals in the industry in general. Despite age and size of firms does not lead to difference among industries, niche width is important for the firms in construction sector for getting co-opetition.Öğe A modeling approach for evaluating green performance of a hotel supply chain(Elsevier Science Inc, 2018) Sari, Kazim; Suslu, MuratThis study aims to develop a tool to evaluate and compare green performances of hotel supply chains. For this purpose, fifteen green criteria, which are then classified as basic green practices and advanced green practices, are extracted from related studies. Later, importance weights of these criteria are determined with the contributions of twenty hotel managers in Turkey. The results indicate that the basic green practices are regarded more important by the managers than the advanced ones. In addition, a fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is proposed to get a green performance score and a ranking for hotel supply chains. In this framework, it is also made possible to reveal the areas need to be improved for them to have a greater green performance. Finally, a numerical example is given to show the applicability and practicability of the proposed model. The results indicate that there is no single strategy to improve a hotel's green performance, but each hotel should analyze its own situation and then determine the most effective strategy accordingly.
