Article Citation - WoS: 14Citation - Scopus: 18Online Purchase Behaviour Among Professionals: a Socio-Demographic Perspective for Turkey(Routledge Journals, Taylor & Francis Ltd, 2014) Akman, Ibrahim; Rehan, MohammadThis study reports the findings of a survey concerning the impact of professionals' selected socio-demographic factors with regard to their online purchasing behaviour in Turkey, since this consumer group plays an important role in adopting new technologies in societies. The survey has been conducted using a 'face-to-face interview' approach during an IT event. To keep in line with the available literature, gender, age, education level, income and daily Internet usage, constitute the socio-demographic variants for this study. Five hypotheses were constructed to investigate the nature of the relationship between the socio-demographic factors and the usage of online purchasing. The chi-square method was selected to test the hypotheses. According to the test results, age, income and education level have a significant impact on the online purchasing behaviour of professionals.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: 5Citation - Scopus: 7The Role of Leadership Cognitive Complexity in Software Development Projects: an Empirical Assessment for Simple Thinking(Wiley, 2011) Akman, Ibrahim; Misra, Sanjay; Cafer, FeridSimple thinking (or simplicity) is a way of coping with complexity. It is especially important in the software development process (SDP), which is an error-prone, time-consuming, and complex activity. This article investigates the role of the thinking style-namely, simple thinking-which has been found effective in solving complicated problems during software development. For this purpose, it reviews and discusses simplicity issues from a general perspective and, then, reports the findings of a survey concerning the assessment of simplicity in SDP. The survey was conducted among information and communication technologies senior professionals and managers from government and private-sector organizations. Relevant hypotheses have been developed under different empirical categories for analysis. Statistical analysis techniques were then used to draw inferences based on these hypotheses. The results have proved simplicity to have a significant role in the SDP to a certain extent.

As the information technology tries to put its best in providing maximum security, user awareness plays a key-role. Additionally, although the literature provides studies on approaches for teaching information security, there are not many evidences on the impact of education level. Therefore, this study investigates the impact of the education level on user security awareness in using the Information and Communication Technology (ICT) products. For this purpose, a survey was conducted among 433 citizens from different layers of the society. Interestingly, the results indicated that education level has significant impact on all security issues included in the analysis regarding computer usage, web usage and e-mail usage.Article Citation - WoS: 24Citation - Scopus: 40An Inheritance Complexity Metric for Object-Oriented Code: a Cognitive Approach(Springer india, 2011) Misra, Sanjay; Akman, Ibrahim; Koyuncu, MuratSoftware metrics should be used in order to improve the productivity and quality of software, because they provide critical information about reliability and maintainability of the system. In this paper, we propose a cognitive complexity metric for evaluating design of object-oriented (OO) code. The proposed metric is based on an important feature of the OO systems: Inheritance. It calculates the complexity at method level considering internal structure of methods, and also considers inheritance to calculate the complexity of class hierarchies. The proposed metric is validated both theoretically and empirically. For theoretical validation, principles of measurement theory are applied since the measurement theory has been proposed and extensively used in the literature as a means to evaluate the software engineering metrics. We applied our metric on a real project for empirical validation and compared it with Chidamber and Kemerer (CK) metrics suite. The theoretical, practical and empirical validations and the comparative study prove the robustness of the measure.Article The Individual Readiness and Risk-Related Concerns of It Professionals for Blockchain Adoption(Elsevier, 2025) Turhan, Cigdem; Akman, IbrahimBlockchain has gained remarkable momentum since its introduction in 2008, drawing the attention of industries, individuals, and governments on a global scale. This technology has been studied in the literature, with a focus on technical aspects, application areas, and emerging research challenges. However, few studies address individuals' perceptions of and concerns with respect to blockchain adoption. This study aims to investigate the attributes affecting blockchain adoption intention. A sample of IT professionals was used for this purpose since they are expected to have earlier and greater awareness of new digital technologies. The perceptions of this group of users regarding attributes such as innovativeness, self-efficacy, social pressure, and awareness, as well as their perceptions of privacy, security, and complexity, were examined through a survey of 208 responses. The results indicate that among the individual attributes, personal innovativeness, awareness, and social pressure positively affect blockchain acceptance, whereas security and privacy concerns fuel the reluctance to adopt blockchain. The findings hopefully provide insight for developers and management of enterprises to ensure a smooth transition into blockchain and present evidence to forecast its future.Article Yazılım Gözden Geçirme Toplantılarında Çevrimiçi İşbirlikçi Araçların Kullanımı Üzerine Öğrencilerle Bir Çalışma(2022) Akman, Ibrahim; Turhan, Çiğdem; Hacaloglu, TunaYazılım geliştirme süreci için takım toplantıları olmazsa olmaz aktivitelerdendir.
