Applying the reductionism concept of the positivist paradigm for information security means missing the bigger picture and thus, the lack of holism which could be one of the reasons why security is still overlooked, comes as an afterthought or perceived from a purely technical dimension. We need to reshape our thinking and attitudes towards security especially in a complex and dynamic environment such as e- Business to develop a holistic understanding of e-Business security in relation to its context as well as considering all the stakeholders in the problem area. In this paper we argue the suitability and need for more inductive interpretive approach and qualitative research method to investigate e-Business security. Our discussion is based on a holistic framework of enquiry, nature of the research problem, the underling theoretical lens and the complexity of e-Business...

Risk adaptive access control models have been gaining more attention in the research community as an alternative approach to overcome the limitations of traditional access control models. Radio Frequency Identification RFID is an emerging technology widely utilized in both physical and logical access control systems because of its contactless nature, low cost, high read/write speed and long distance operation. Serverless RFID system architecture offers better availability assurance and lower implementation cost, while access rights management is easier in server-based architecture. In this study, we continue to build on our previous research on the privacy and security of RFID access control systems without a backend database in order to overcome its limitations. We propose a hybrid design for a risk adaptive RFID access control system; that is, dynamically alternating between two access control modes, online server-based and offline serverless, to adapt to the level of risk depending on rule-based risk scenarios and current risk value. The proposed design combines features of both serverless and risk adaptive access control systems. Copyright © 2015 John Wiley & Sons, Ltd.

It has been introduced in the literature as interconnection network suitable for large parallel computers, which can connect large number of nodes with three links per node. Although this topology exhibits attractive characteristics such as embeddability, symmetry, regularity, strong resilience, and simple routing, the previously suggested routing algorithms suffer from the high number of logical operations and the need for readdressing of nodes every time a new level is add to the network. This negatively impacts the performance of the network as it increases the execution time of these algorithms. In this paper we propose an improved optimal point to point routing algorithm for Hex-Cell network. The algorithm is based on dividing the Hex-Cell topology into six divisions, hence the name Section Based Hex-Cell Routing (SBHCR). The SBHCR algorithm is simple and preserves the advantage of the addressing scheme proposed for the Hex-Cell network. It does not depend on the depth of the network topology which leads to overcome the issue of readdressing of nodes every time a new level is added. Evaluation against two previously suggested routing algorithms has shown the superiority of SBHCR in term of less logical operations.

The research developed a TAM-EL (Technology Acceptance Model for E-learning) for predicting the intention to adopt E-Learning using the constructs of the Technology Acceptance Model (TAM). TAM-EL proposes that Perception of usefulness of technology, Perception of ease of use of the technology, Patronised (degree of support for the technology), and Practised (previous experience with the technology) influence attitude towards the adoption of E-Learning. Data was collected from 380 undergraduate students to test the model. Factor analysis and confirmatory factor analysis were used to validate the instrument, however; the partial least square method was used to test the model for the study, moreover; stepwise regression analysis were used to test the hypotheses of the study. The findings indicate that students have an important role as stakeholders in the adoption of E-Learning in Jordan. While the variable of Attitude contributes to approximately 57% of the variance in the Prediction of E-Learning, the variable of Patronised contributes only approximately 28% of the variance in the Prediction of E-Learning. Moreover, the findings show an obvious recommendation is the need to engage users in a more determined manner.

Although the Hex-Cell network represents an interesting network topology with features such as the capability of embedding several topological structures and extensibility at a minimal cost; yet it needs an efficient routing algorithm in order to fully benefit from these interesting features. This paper proposes a new routing algorithm for Hex-Cell network. This routing algorithm is based on a new addressing mode which utilises the addresses of the two neighbours' cells of each source and destination nodes. The proposed routing algorithm uses two levels of routing: internal Node Routing which operates between the nodes within the cell and external Cell Routing which route messages from cell to cell. This concept is very useful with structure of Hex-Cell network specifically for grouping (clustering) six processors as one component (Cell) and there are central processor which organises these processors; therefore, Cell Routing can be used for routing from one group to another group, and for internal routing each group may us the proposed Node Routing or any another centre or distribute routing algorithm.

This work proposes a congestion rate estimation approach that relies on real-time video scenes of road traffic, and was implemented and evaluated on eight different hotspots covering 33 different urban roads. The approach relies on road scene morphology for estimation of vehicles average speed along with measuring the overall video scenes randomness acting as a frame texture analysis indicator. Experimental results shows the feasibility of the proposed approach in reliably estimating traffic density and in providing an early warning to drivers on road conditions, thereby mitigating the negative effect of slow traffic flow on their daily lives.

We and others argue that governments can and should play a major role in providing a reliable and secure environment for online businesses because they have a major stake in growing the economy. Our finding from previous research indicates that security is usually overlooked; it comes as an afterthought or is perceived from a purely technical dimension. This study attempts to describe and analyze the current role of the government of Jordan in facilitating the security of e-business. Our starting premise is that governments should recognize the full range of socio-technical implications that security may have on the adoption of e-business. This can be achieved by understanding the real security needs and concerns of the various stakeholders at the different e-business stages and then aligning them to its policy and plans. Moreover, we argue that in order for the government to be an effective partner in developing a secure e-business environment, legislating laws and regulations is insufficient; instead, governments must increase security education and awareness, ensure compliance with security standards and regulations, and protect the country’s critical ICT infrastructure.
