The sourcing of cloud services is a relatively new type of service delivery model in which an organization gets access to IT services via a cloud service provider that is delivering services over the web to many users on a pay per use or period basis. Even though the importance of IT governance is often underlined, there is limited literature available regarding the required IT governance capabilities that public sector organizations need to have in place to successfully implement and manage a cloud service delivery model. Using an existing governance framework of IT core capabilities as basis, the required cloud computing capabilities are investigated using interviews and studying reports. The analyses helped to identify 16 discriminating capabilities that are essential when effectively implementing and managing cloud services in the public sector. Different factors, including the cloud service and deployment model, the strategic intent underlying cloud sourcing, the degree and complexity of cloud sourcing and the IT governance structure, were found to influence the relevance of cloud capabilities and the relevance might also change over time.

Virtual-currency has become an important service and brought a great profit to SNS companies in China. In this paper, based on some economic theory and algorithms, we systematically analyze the operation mechanisms of the virtualcurrency in China. Three models, the ideal model, the actual model and the improved model are given to illustrate how virtual-currency services bring profit to SNS service suppliers. Moreover, in the improved model we propose a novel withdrawal mechanism: unlike the other two models, the improved model allows the users using virtual money to buy real goods. This mechanism can bring more profit to the SNS companies. A survey among 859 SNS users of mainland in China is conducted to evaluate the feasibility of our proposed model. The results of the survey showed that SNS companies should consider the additional mechanism for users to exchange real goods with virtual-currency, a win-win situation for all parties in SNS development.

When an SOA business process fails to deliver the desired quality of service (QoS), it is necessary to identify the faulty services that cause the problem since the source of the problem may not be at where the problem is observed. In this paper, we propose a polynomial time diagnosis algorithm by using a dependency matrix for business process structure in SOA. The dependency matrix is built based only on process workflow structure, with no need for historical knowledge on prior executionx. By comparing the performance data reported from business process probes, the proposed diagnosis algorithm also checks some predicates-on-probes (PoP) to increase the monitoring and diagnosis accuracy. We have implemented the diagnosis support for the dependency matrix based QoS management in the Llama middleware. A performance study using some realistic services running on networked Web servers shows that the system can achieve a diagnosis completeness of up to 80%.

Electronic Business (or “e-Business”) is the utilization of information and communication technologies (ICT) in support of various types of business activities. As the economy becomes globalised and organisations are evolving to become service-oriented, together with recent rapid advancement of ICT, especially the Internet, many challenges as well as opportunities have arisen (Chiu, 2010). For example, recent advancement in service computing, mobile computing, cloud computing, and business intelligence applications has wide and deep impact on how businesses are being performed (Leung et al., 2011). Efficiencies and effectiveness have general been much improved, while complexities have emerged. Various emerging social, legal, and ethical issues have also drawn wide attention (Chiu et al., 2009). Therefore, knowledge from various disciplines is required to achieve excellence in e-Business in response to the ever complicating requirements in the rapidly evolving global environment. The industry and academia has also been shifting the focus to a cross-disciplinary and holistic approach. The creation, operation, and evolution of the research and practice in e-Business raise concerns that range from highlevel requirements and business modelling through to the deployment of specific implementation technologies and paradigms, as well as involve a wide (and ever growing) range of methods, tools, and technologies. They also cover a broad spectrum of vertical domains, industry segments, and even government sectors. As such, this journal aims at providing an open, formal publication for high quality articles developed by theoreticians, researchers, managers, educators, developers, and practitioners for professionals to face the multiple dimensions and aspects of the opportunities and challenges of e-Business. Articles of this journal are encouraged to present novel combination of multiple aspects of e-Business such as (but are not limited to):
电子商务(或“电子商务”)是利用信息和通信技术(ICT)来支持各种类型的商业活动。随着经济变得全球化，组织正在演变为以服务为导向，加上最近信息通信技术的快速发展，特别是互联网，许多挑战以及机遇已经出现(邱，2010)。例如，服务计算、移动计算、云计算和商业智能应用的最新进展对业务的执行方式产生了广泛而深刻的影响(Leung et al.， 2011)。效率和效力总体上有了很大提高，但也出现了复杂性。各种新出现的社会、法律和伦理问题也引起了广泛关注(Chiu et al.， 2009)。因此，要在电子商务方面取得卓越的成就，必须具备不同学科的知识，以应付迅速发展的全球环境中日益复杂的要求。业界和学术界也一直在将重点转向跨学科和整体的方法。电子商务研究和实践的创建、操作和发展引起了从高层次需求和业务建模到具体实现技术和范例的部署的关注，并且涉及范围广泛(并且不断增长)的方法、工具和技术。它们还涵盖了广泛的垂直领域、行业部门，甚至政府部门。因此，本刊旨在为理论家、研究人员、管理人员、教育工作者、开发人员和实践者撰写的高质量文章提供一个开放、正式的出版物，供专业人士面对电子商务的多个维度和方面的机遇和挑战。本杂志鼓励文章介绍电子商务多个方面的新颖组合，例如(但不限于):
