Although it has a high potential to influence organizational strategies for adoption into respective operations, it has not been widely explored yet. This study aims to assess the sectoral diversity in the timing of organizational adoption of blockchain through selected organizational factors. Design/methodology/approach A survey was conducted based on a sample of 208 IT professionals. The data was collected using an instrument containing 17 questions. The existence of sector diversity was statistically analyzed using the Least Square Regression method. Findings The results indicate that, except for management support and perceived ease of use, all the other factors in the analysis significantly influence sector diversity in terms of blockchain adoption timing. Originality/value Although blockchain has received attention from researchers, to the best of the authors' knowledge, there is no published work in the literature that explores the organizational factors influencing sectoral differences in the timing of blockchain technology adoption. Therefore, our work is unique in the related literature since we present analyses for the diversity between public and private sectors by modeling the factors affecting the intentions for the timing of blockchain adoption as part of the organizations' IT infrastructure.Article Citation - WoS: 10Citation - Scopus: 17Investigation of Employers' Performance Expectations for New It Graduates in Individual and Team Work Settings for Software Development(Emerald Group Publishing Ltd, 2018) Akman, Ibrahim; Turhan, CigdemPurpose - In general, software development work environments involve many different tasks and have high demands on efficiency and quality of performance at both individual and team levels, which depend on the competencies of employees. However, the literature does not provide satisfactory evidence as for the characteristics and competencies of individuals. Especially, the employers' expectations of new graduates have not been investigated in detail for different work environments. The purpose of this paper is to examine employers' expectancies regarding technical, personal and educational competencies among IT-graduated employees to provide a comparison between individual and team work settings. Design/methodology/approach - A survey approach was used for this purpose, and the research model was tested using multiple regression. Findings - The results revealed that significant diversity exists in individual and team work settings regarding employers' expectations for new graduates' competencies in terms of adapting to new software development methods and approaches, using time effectively and experience gained in undergraduate projects. Originality/value - The results of this study will yield insight to computer-related departments in curriculum development by providing a comparison between the varying competencies required in individual and team work settings from the employer's perspective. In the long run, the aim is to meet employers' demands of the new graduates' competencies, resulting in better individual and team performances in information technology companies, thereby leading to successful software development.Article Education With Experience: Assessment of a Co-Op Model in Undergraduate Engineering Programs in Computing(Ieee Computer Soc, 2023) Nazlioglu, Selma; Turhan, Cigdem; Yazici, AliA major concern among graduates of computing departments is the discrepancy between the expectations of software companies and the competencies provided by the academic departments. This ongoing problem makes co-op education inevitable, as it combines industrial experience with traditional education.Article Citation - WoS: 27Citation - Scopus: 43User Acceptance of Social Learning Systems in Higher Education: an Application of the Extended Technology Acceptance Model(Routledge Journals, Taylor & Francis Ltd, 2017) Akman, Ibrahim; Turhan, CigdemThis study aims to explore the users' behaviour and acceptance of social media for learning in higher educational institutions with the help of the extended Technology Acceptance Model (TAM). TAM has been extended to investigate how ethical and security awareness of users affect the actual usage of social learning applications. For this purpose, a survey was conducted and the Structural Equation Model approach was utilised to investigate the direct and indirect causal relationships among the constructs in the research model. Interestingly, the findings from the analysis reveal that, except ease of use', TAM's core and external constructs are significant predictors of actual behaviour towards using social media for learning.Article Citation - WoS: 2Citation - Scopus: 3A Hybrid Approach for Semantic Image Annotation(Ieee-inst Electrical Electronics Engineers inc, 2021) Sezen, Arda; Turhan, Cigdem; Sengul, GokhanIn this study, a framework that generates natural language descriptions of images within a controlled environment is proposed. Previous work on neural networks mostly focused on choosing the right labels and/or increasing the number of related labels to depict an image. However, creating a textual description of an image is a completely different phenomenon, structurally, syntactically, and semantically. The proposed semantic image annotation framework presents a novel combination of deep learning models and aligned annotation results derived from the instances of the ontology classes to generate sentential descriptions of images. Our hybrid approach benefits from the unique combination of deep learning and semantic web technologies. We detect objects from unlabeled sports images using a deep learning model based on a residual network and a feature pyramid network, with the focal loss technique to obtain predictions with high probability. The proposed framework not only produces probabilistically labeled images, but also the contextual results obtained from a knowledge base exploiting the relationship between the objects. The framework's object detection and prediction performances are tested with two datasets where the first one includes individual instances of images containing everyday scenes of common objects and the second custom dataset contains sports images collected from the web. Moreover, a sample image set is created to obtain annotation result data by applying all framework layers. Experimental results show that the framework is effective in this controlled environment and can be used with other applications via web services within the supported sports domain.Conference Object Citation - Scopus: 3English to Turkish example-based Machine Translation with Synchronous SSTC(Ieee Computer Soc, 2008) Alp, N. Deniz; Turhan, CigdemExample Based Machine Translation (EBMT) is a corpus-based method which is based on using previously translated text. In this project, English to Turkish EBMT system has been developed which uses the Synchronous SSTC for the representation of the sentences in the parallel corpora. This method proves to be effective especially in structurally different languages such as English and Turkish.Article Citation - WoS: 8Citation - Scopus: 10Employability of It Graduates From the Industry's Perspective: a Case Study in Turkey(Springer, 2013) Turhan, Cigdem; Akman, IbrahimThe qualifications that constitute the employability and identity of graduates are viewed differently by the academic community and the industry. Currently, it is observed for Information Technologies (IT) sector that the demands of the industry are not always satisfied by the perceived standards of the graduates. To provide feedback to the corresponding departments, a survey regarding employer expectations and factors affecting these expectations has been conducted among a number of senior professionals and managers working in the IT sector in Turkey regarding this inconsistency. The employer expectations are considered in two empirical categories as competencies and adequacies. The multiple regression analysis technique has been used to analyze the survey data. Based on the analysis, recommendations are provided to IT departments as well as their students to better fulfill the demands of the industry.Article Citation - WoS: 3Citation - Scopus: 4Sector Diversity among IT Professionals in the Timing of Blockchain Adoption: an Attitudinal Perspective(Kaunas Univ Technol, 2022) Akman, Ibrahim; Turhan, CigdemBlockchain technology has the potential to reshape the conventional ways of processes and transactions on digital platforms. Much of the attention surrounding blockchain is mainly focused on the technical and organizational aspects. Comparatively, little effort has been targeted towards understanding the attitudinal issues in blockchain adoption. This study aims to explore the role of attitudinal forms behind the intended timing of IT professionals' blockchain adoption, with an emphasis on the differences between the public and private sectors. A survey method was used where the data was collected from 208 IT professionals from public and private sector establishments in order to investigate how the different attitudes of the participants as well as the differences in their work sectors affect their intention to adopt blockchain. The data collected was analysed with ordinal logistic regression and the results indicate that the participants' affective, normative and pessimistic attitudes have a significant effect on the timing of blockchain adoption, and that these effects show differences among the IT professionals from the public and private sector. The findings are believed to provide valuable information to researchers and strategists in forecasting the future evolution of the blockchain technology in terms of individual utilization. The results also will provide feedback to managers of different sectors in making decisions regarding blockchain adoption, developers of blockchain services, as well as individuals who are interested in using blockchain.Article Citation - WoS: 1Citation - Scopus: 1Integration of Social Media Into Engineering Education: a Comparative Study on Perceptions of Faculty and Students(Tempus Publications, 2018) Turhan, Cigdem; Akman, Ibrahim; Software Engineering; Computer EngineeringFor a number of years, the effects of incorporating social media into education systems has invoked the interest of researchers, academicians and students. Yet, the enthusiasm of students in utilizing social media for learning is met with reluctance on the faculty's part in abandoning the traditional ways of teaching. This study compares the students' and faculty's acceptance of the utilization of social media in engineering education from different perspectives. A survey approach has been used for this purpose and 57 faculty and 85 students from the engineering faculties participated in the study. The research model used was tested using the least square regression technique. The results show existence of significant diversity between the faculty and students in the factors affecting the ethical usage. Concerning the general usage, this diversity exists in only the awareness. These results are expected to provide insight into the issues that act as barriers towards a more open, collaborative and learner-centered higher education platform.
