Data Dissemination And Information Diffusion In Social Networks

Data dissemination problem is a challenging issue in social networks, especially in mobile social networks, which grows rapidly in recent years worldwide with a significant increasing number of hand-on mobile devices such as smart phones and pads. Short-range radio communications equipped in mobile devices enable mobile users to access their interested contents not only from access points of Internet but also from other mobile users. Through proper data dissemination among mobile users, the bandwidth of the short-range communications can be better utilized and alleviate the stress on the bandwidth of the cellular networks. In this dissertation proposal, data dissemination problem in mobile social networks is studied. Before data dissemination emerges in the research of mobile social networks, routing protocol of finding efficient routing path in mobile social networks was the focus, which later became the pavement for the study of the efficient data dissemination. Data dissemination priorities on packet dissemination from multiple sources to multiple destinations while routing protocol simply focus on finding routing path between two ends in the networks. The first works in the literature of data dissemination problem were based on the modification and improvement of routing protocols in mobile social networks. Therefore, we first studied and proposed a prediction-based routing protocol in delay tolerant networks. Delay tolerant network appears earlier than mobile social networks. With respect to delay tolerant networks, mobile social networks also consider social patterns as well as mobility patterns. In our work, we simply come up with the prediction-based routing protocol through analysis of user mobility patterns. We can also apply our proposed protocol in mobile social networks. Secondly, in literature, efficient data dissemination schemes are proposed to improve the data dissemination ratio and with reasonable overhead in the networks. However, the overhead may be not well controlled in the existing works. A social-aware data dissemination scheme is proposed in this dissertation proposal to study efficient data dissemination problem with controlled overhead in mobile social networks. The data dissemination scheme is based on the study on both mobility patterns and social patterns of mobile social networks. Thirdly, in real world cases, an efficient data dissemination in mobile social networks can never be realized if mobile users are selfish, which is true unfortunately in fact. Therefore, how to strengthen nodal cooperation for data dissemination is studied and a credit-based incentive data dissemination protocol is also proposed in this dissertation. Data dissemination problem was primarily researched on mobile social networks. When consider large social networks like online social networks, another similar problem was researched, namely, information diffusion problem. One specific problem is influence maximization problem in online social networks, which maximize the result of information diffusion process. In this dissertation proposal, we proposed a new information diffusion model, namely, sustaining cascading (SC) model to study the influence maximization problem and based on the SC model, we further plan our research work on the information diffusion problem aiming at minimizing the influence diffusion time with subject to an estimated influence coverage

Nodal policing in the Netherlands

This article focuses the nodal orientation of the police, which is an innovative and controversial target of Dutch policing. This target states that the police should focus on flows, and on places where the various flows coincide. The success factors for implementation nodal policing are discussed as well as its (strategic) implications for Dutch policing. We focus on the key features of Dutch nodal policing; the strategies that have been followed to implement nodal policing, the current state of affairs of nodal policing in The Netherlands, and what the future prospects for nodal policing in The Netherlands are

Protection of intellectual property rights an Indian perspective

The objective of this paper is to provide an overview of the Indian Innovation System, IPR system and other related activities such as Judicial System, Enforcement System, and Academic Institutions etc. The paper is based on the existing data and relates those data and results to the India’s Intellectual Property Rights System, Innovation, Research and Development. This paper focus on the recent reforms in IPR laws to achieve a legal framework for protecting IPR that is comparable to that of most developed nations. As a part Information Technology, three major IT organizations focus on innovation and research discussed in addition to an overview about major multinational companies’ research initiatives in India

Northern Periphery Programme Preparatory Project - Arctic Collaboration Mechanism

This final report of the ‘Northern Periphery Programme Preparatory Project – Arctic Collaboration Mechanism’ details project progress and results to date and sets out the final steps for the project. The report draws on a synthesis of past project outputs and new research and consultation. The overall aims of the project are to consider the need for improved collaboration across regional economic development programmes in the Arctic and High North, and how a collaboration mechanism can be optimally structured and delivered

Making Poverty History? How Activists, Philanthropists, and the Public Are Changing Global Development

From August 1 to 3, 2007, fifty preeminent U.S. and international experts from government, business, academia, and the philanthropic and nonprofit sectors came together at the Aspen Institute to explore the changing contours of the global development community. By examining the common challenges development actors face -- promoting accountability, using resources effectively, and achieving scale and sustainability -- participants aimed to spur successful practices and establish foundations for collaboration among the expanding field of players determined to lift the lives of the world's poorest people

Review of agricultural extension in India: Are farmers' information needs being met?

Despite a wide range of reform initiatives in agricultural extension in India in the past decades, the coverage of, access to, and quality of information provided to marginalized and poor farmers is uneven. This paper aims to ascertain why farmers are not accessing information and where information gaps exist, despite the variety of extension approaches in India. Using information provision and access as the basis for analysis, the paper reviews some of the major agricultural extension programs in India by considering their ability to provide information and facilitate information sharing and use in farming communities. The review gives a broad overview of the current extension scene in India while providing a synthesis of recent debates and the observations of various authors as well as working groups in the Ministry of Agriculture and the Planning Commission. The paper examines the challenges and constraints of each agricultural extension approach as it attempts to provide farmers with access to information that is relevant to their farm enterprises. As a result of this analysis, opportunities are identified for increasing extension services' effectiveness and efficiency in reaching smallholder farmers. Research gaps are also identified. The review concludes that there is an increasing need to work in partnership and to share knowledge and skills in order to provide locally relevant services that meet the information needs of marginal and smallholder farmers in India.agricultural extension, Knowledge, information, Innovation, Public-private partnership, Gender, Education,
