Currently, user group has become an effective platform for information sharing and communicating among users in social network sites. In present work, we propose a single topic user group discovering scheme, which includes three phases: topic impact evaluation, interest degree measurement, and trust chain based discovering, to enable selecting influential topic and discovering users into a topic oriented group. Our main works include (1) an overview of proposed scheme and its related definitions; (2) topic space construction method based on topic relatedness clustering and its impact (influence degree and popularity degree) evaluation; (3) a trust chain model to take user relation network topological information into account with a strength classification perspective; (4) an interest degree (user explicit and implicit interest degree) evaluation method based on trust chain among users; and (5) a topic space oriented user group discovering method to group core users according to their explicit interest degrees and to predict ordinary users under implicit interest and user trust chain. Finally, experimental results are given to explain effectiveness and feasibility of our scheme. © 2016 Wang Dong et al.

As advances in life sciences and information technology bring profound influences on bioinformatics due to its interdisciplinary nature, bioinformatics is experiencing a new leap-forward from in-house computing infrastructure into utility-supplied cloud computing delivered over the Internet, in order to handle the vast quantities of biological data generated by high-throughput experimental technologies. Albeit relatively new, cloud computing promises to address big data storage and analysis issues in the bioinformatics field. Here we review extant cloud-based services in bioinformatics, classify them into Data as a Service (DaaS), Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), and present our perspectives on the adoption of cloud computing in bioinformatics.This article was reviewed by Frank Eisenhaber, Igor Zhulin, and Sandor Pongor. © 2012 Dai et al.; licensee BioMed Central Ltd.

We start out from the premise of a continued need for policy integration to address both economic and environmental issues in society, arguing that spatial planning is a privileged site to locate such endeavor. While policy integration in planning can acquire many forms, we understand those forms as ways to manage interdependencies between organizations. Spatial planning can contribute to the integration of policies in comprehensive visions, but a planning system, in the sense of a network of organizations, does not escape from the evolutionary rigidity introduced by interdependence and path-dependence. In a study of the evolutionary path of spatial governance in Uzbekistan, a former Soviet republic, we investigated the shifting patterns of policy integration that affected the organization of space. Policy integration in planning, it is found, is path-dependent, worked out positively and negatively, and necessarily relied on informal coordination mechanisms. Thus, a planning system striving to manage interdependence has to be highly reflexive, to understand the extent to which its transformation options are constrained by history and by present linkages between organizations. © 2011 Elsevier Ltd.

Surviving in an increasing globalization, distribution and flexibility environment, modern manufacturing requires an extremely flexible, self-adaptive foundation capable of dynamic provisioning, coordinating and using infinite manufacturing resources available on demand over large-scale computer networks. In contrast to the conventional networked manufacturing approach, the cloud manufacturing vision (GetCM) introduced in this paper promises elasticity, flexibility and adaptability through the on-demand provisioning of manufacturing resources as a utility by reflecting the basic principles of cloud computing. The discussion is made from technological, functional, economic aspects to provide evidence of the benefits from GetCM in the context of networked manufacturing resource access, provision, sharing and coordination. A primary architecture for GetCM is introduced based on the analysis of key criteria in realizing the vision of a function for cloud manufacturing. Focuses of this paper are placed on the vision and the outline of GetCM architecture. © (2011) Trans Tech Publications.

In this paper, we adopt a Foucauldian perspective on power/knowledge interactions to investigate the evolution and implementation of policy for the Romanian Danube delta. We argue that a better understanding of the potential for citizen participation in environmental governance can be obtained from a careful analysis of the pathways of emergence, enactment and implementation of policies affecting an area. Policies are seen as temporary conceptual structures coordinating knowledge and power, in constant transmutation because of the confrontation with other power/knowledge configurations. For the Danube delta, it is argued that policies originating at various levels of government co-create a 'local' that is scrutinized, silenced, exoticized, subjugated and marginalized. Finally, we investigate the implications of this and similar processes of delineation of actors for participatory natural resource governance. © 2011 Taylor & Francis.
