    Exploring Supportive and Deterrent Factors on Online Shopping in a Developing Country
    (Igi Global, 2020) Pusatli, Tolga; Akman, Ibrahim
    This study explores the influence of the reasons of individuals' supportive and deterrent behaviors against commercial usage of online media in the emerging market of Turkey. The supportive and deterrent factors are grouped in empirical categories as discouragement and encouragement, respectively. The impact of these factors on actual behavior were assessed via intermediary empirical category including the variables inefficiency, efficiency, intention, and subjective norm. A survey was conducted using a sample of 251 observations obtained from the visitors of three large/busy malls using purposive sampling. The multiple least-square regression was utilized to test the nature of the relationships between variables. Results indicated a significant discouraging impact of warranty, finance, habits, security on inefficiency perceptions, an encouraging impact of geography and convenience on efficiency perceptions. Significant behavioral impact of perceptions regarding inefficiency, efficiency, subjective norms, and intention on actual usage of online shopping was also observed.

    Integration 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 Engineering
    For 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.

    The Role of Leadership Cognitive Complexity in Software Development Projects: an Empirical Assessment for Simple Thinking
    (Wiley, 2011) Akman, Ibrahim; Misra, Sanjay; Cafer, Ferid
    Simple 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. (C) 2011 Wiley Periodicals, Inc.

    Impact of Education on Security Practices in Ict
    (Univ Osijek, Tech Fac, 2015) Bostan, Atila; Akman, Ibrahim
    In assuring the security in information technology, user awareness and acquired-user habits are inevitable components, yet they may be qualified as the feeblest ones. 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.

    An Inheritance Complexity Metric for Object-Oriented Code: a Cognitive Approach
    (Springer india, 2011) Misra, Sanjay; Akman, Ibrahim; Koyuncu, Murat
    Software 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.

    A Cognitive Model for Meetings in the Software Development Process
    (Wiley, 2014) Misra, Sanjay; Akman, Ibrahim
    Meetings are at the heart of the software development process (SDP) and can be of different types. The present article first proposes an abstract cognitive model for meetings, which represents how different types of meetings are affected by cognitive activities at different stages within the SDP. Second, and based on the analysis of meetings at different stages of SDP, it proposes the removal of such meetings from some of the stages within the program by using a cognitive evaluation model for meetings and their replacement, instead, with information and communication technology tools and techniques by means of a cognitive evaluation model. The abstract cognitive model and the evaluation model are validated empirically through experimentation, carried out through a detailed analysis of a target group composed of information technology professionals.

    Assessing Software Quality Using the Markov Decision Processes
    (Wiley-blackwell, 2014) Korkmaz, Omer; Akman, Ibrahim; Ostrovska, Sofiya
    Quality of software is one of the most critical concerns in software system development, and many products fail to meet the quality objectives when constructed initially. Software quality is highly affected by the development process's actual dynamics. This article proposes the use of the Markov decision process (MDP) for the assessment of software quality because MDP is a useful technique to abstract the model of dynamics of the development process and to test its impact on quality. Additionally, the MDP modeling of the dynamics leads to early prediction of the quality, from the design phases all the way through the different stages of development. The proposed approach is based on the stochastic nature of the software development process, including project architecture, construction strategy of Software Quality Assurance system, its qualification actions, and team assignment strategy. It accepts these factors as inputs, generating a relative quality degree as an output. The proposed approach has been demonstrated for the design phase with a case study taken from the literature. The results prove its robustness and capability to identify appropriate policies in terms of quality, cost, and time. (c) 2011 Wiley Periodicals, Inc.

    Applicability of Weyuker's Properties on Oo Metrics: Some Misunderstandings
    (Comsis Consortium, 2008) Misra, Sanjay; Akman, Ibrahim
    Weyuker's properties have been suggested as a guiding tool in identification of a good and comprehensive complexity measure by several researchers. Weyuker proposed nine properties to evaluate complexity measure for traditional programming. However, they are extensively used for evaluating object-oriented (OO) metrics, although the object-oriented features are entirely different in nature. In this paper, two recently reported OO metrics were evaluated and, based on it; the usefulness and relevance of these properties for evaluation purpose for object-oriented systems is discussed.

    The Impact of Cognitive and Socio-Demographic Factors at Meetings During Software Development Process
    (Univ Osijek, Tech Fac, 2011) Akman, Ibrahim; Misra, Sanjay; Altindag, Tugba; Computer Engineering
    Most of the important decisions are taken at team meetings during software development process (SDP) and the way of thinking of project leader plays an important role in achieving quality objectives at these team meetings. Considering this important issue, this paper investigates the impact of cognitive and socio-demographic factors on manager's simple thinking style towards improving the quality of team meetings in SDP. We have performed experimentations among Information and Communication Technologies' (ICT) senior professionals and managers from government and private sector organizations for this purpose. The hypotheses have been developed under different empirical categories and then statistical analysis techniques have been used to draw inferences. The results indicate that "type of team meetings", "project leader's cognitive characteristics" and "adoption of a cognitive model at team meetings" have statistically significant impact on manager's simple thinking in terms of improving productivity and contribution of team meetings.
