The purpose of this research work is to find a methodology for the strategic development of competitive advantage for information technology (IT) companies (Mezger and Violani, 2011). The ultimate aim of this project is to develop a methodological approach on this issue, based on dynamic simulation models (DSM) (Wirahadikusumah and Abraham, 2003). With the aid of DSM, senior managements of organizations will have the opportunity to make decisions of assured success. This success shall be guaranteed by the realization of entrepreneurial activity in a safe and inexpensive computing environment before actual investment.

This paper highlights the advantages of the dynamic modelling of systems aiming at developing competitive advantage for IT companies (Ordóñez de Pablos, 2006). In this research, we have used the science of design and the research methodology for testing the concept of modelling as well as the process of modelling. The models have been completed through a series of alternations and iterations in the design, development, simulation, testing and evaluation.

This paper examines the interface among several dimensions for the development of dynamic models. The validity and usefulness of those models in the process of decision-making has been confirmed by the usage of dynamic models in various sectors.

This paper applies the system and the concepts of dynamic modelling, which are pioneering elements as to their nature and evolution. Although the sector, where the modelling was applied, is an IT company, the concepts and principles investigated, developed and validated can be applied to most enterprises.

The purpose of this paper is to investigate risk reduction strategies in online shopping through the perspective of buyer’s trust.

An explanatory research approach is adopted to identify cause-and-effect relationships between e-quality and customers’ loyalty, satisfaction and trust. This approach is accomplished through field research, which is based on a structured questionnaire that utilizes the E-S-QUAL tool, which is a multiple-item general scale for measuring electronic service quality. The sample is consisted of 92 e-buyers (consumers).

The field research revealed that three e-quality dimensions, namely, ease of use, customization and assurance, e-scape and responsiveness, have significant positive effects on e-loyalty and e-satisfaction. Regarding e-trust, only customization and assurance exerts a significant positive effect.

The field research provides in-depth understanding of relationships among e-loyalty, e-satisfaction and e-trust. The majority of the respondents are young people living in Athens, Greece, highly educated, with a relative low monthly income.

This study investigates how trust is affecting the consumers’ engagement to e-commerce, suggesting the appropriate security that should be taken to mitigate perceived risks. Reviewing security measures can help reduce risks of an e-company and simultaneously enforce the level of trust and customers' intentions to buy.

The purpose of this paper is to examine the factor “Staff's beliefs, attitudes and social representations” vis‐à‐vis the part it plays during the negotiation process in the effort of the two leaders of the Greek banking branch to merge.

The codification is attempted by means of software, so as to clarify the trends for negotiations in win‐win conditions. Data were collected by the negotiation process of two large banking companies.

The paper concludes that the private or public character of each banking organization involved in the negotiation process of aiming at a merger will affect its strategic choices in relation to the role played by human beliefs and professional attitudes during the negotiations. Additionally, the research has pointed out some elements that are explained and justified by the existing circumstances in the particular banking area. The fear of change, the stress, the insecurity and the loss of morale are also pointed out as being significant factors.

The paper is based on research of two different sectors – private and public – and how the employees of two organizations belonging to these sectors react and affect the result of the merger.

The purpose of this paper is to provide an integrated analysis base to facilitate computational neuroscience experiments, following a user-led approach to provide access to the integrated neuroscience data and to enable the analyses demanded by the biomedical research community.

The design and development of the N4U analysis base and related information services addresses the existing research and practical challenges by offering an integrated medical data analysis environment with the necessary building blocks for neuroscientists to optimally exploit neuroscience workflows, large image data sets and algorithms to conduct analyses.

The provision of an integrated e-science environment of computational neuroimaging can enhance the prospects, speed and utility of the data analysis process for neurodegenerative diseases.

The N4U analysis base enables conducting biomedical data analyses by indexing and interlinking the neuroimaging and clinical study data sets stored on the grid infrastructure, algorithms and scientific workflow definitions along with their associated provenance information.

The purpose of this paper is to investigate the association of lack of awareness and human factors and the association of lack of awareness and significant attacks that threat computer security in higher education.

Five human factors and nine attacks are considered to investigate their relationship. A field research is conducted on Greek employees in higher education to identify the human factors that affect information security. The sample is consisted of 103 employees that use computers at work. Pearson correlation analysis between lack of awareness and nine (9) computer security risks is performed.

Examining the association of lack of awareness with these attacks that threat the security of computers, all nine factors of important attacks exert significant and positive effect, apart from phishing. Considering the relationship of lack of awareness to human factors, all five human factors used are significantly and positively correlated with lack of awareness. Moreover, all nine important attacks, apart from one, exert a significant and positive effect.

The paper extends understanding of the relationship of the human factors, the lack of awareness and information security. The study has focused on employees of the Technological Educational Institute (TEI) of Athens, namely, teachers, administrators and working post-graduate students.

The paper has used weighted factors based on data collection in higher education to calculate a global index for lack of awareness, as the result of the weighted aggregation of nine (9) risks, and extends the analysis performed in the literature to evaluate the effectiveness of security awareness in computer risk management.
