Mapping Big Data into Knowledge Space with Cognitive Cyber-Infrastructure

Big data research has attracted great attention in science, technology, industry and society. It is developing with the evolving scientific paradigm, the fourth industrial revolution, and the transformational innovation of technologies. However, its nature and fundamental challenge have not been recognized, and its own methodology has not been formed. This paper explores and answers the following questions: What is big data? What are the basic methods for representing, managing and analyzing big data? What is the relationship between big data and knowledge? Can we find a mapping from big data into knowledge space? What kind of infrastructure is required to support not only big data management and analysis but also knowledge discovery, sharing and management? What is the relationship between big data and science paradigm? What is the nature and fundamental challenge of big data computing? A multi-dimensional perspective is presented toward a methodology of big data computing.Comment: 59 page

Towards distributed architecture for collaborative cloud services in community networks

Internet and communication technologies have lowered the costs for communities to collaborate, leading to new services like user-generated content and social computing, and through collaboration, collectively built infrastructures like community networks have also emerged. Community networks get formed when individuals and local organisations from a geographic area team up to create and run a community-owned IP network to satisfy the community’s demand for ICT, such as facilitating Internet access and providing services of local interest. The consolidation of today’s cloud technologies offers now the possibility of collectively built community clouds, building upon user-generated content and user-provided networks towards an ecosystem of cloud services. To address the limitation and enhance utility of community networks, we propose a collaborative distributed architecture for building a community cloud system that employs resources contributed by the members of the community network for provisioning infrastructure and software services. Such architecture needs to be tailored to the specific social, economic and technical characteristics of the community networks for community clouds to be successful and sustainable. By real deployments of clouds in community networks and evaluation of application performance, we show that community clouds are feasible. Our result may encourage collaborative innovative cloud-based services made possible with the resources of a community.Peer ReviewedPostprint (author’s final draft

Understanding the changing nature of sports organisations in transforming societies

The paper examined the process of changing in three Bulgarian national sport organisations (NSO) in swimming, weightlifting and field hockey, as the country is undergoing fundamental political, economic and social transformations from state socialism (1945-1989) to democratisation (1990-present). Drawing on the contextualist approach to organisational change (Pettigrew, 1985) the study was concerned with understanding long-term processes in their context. Analysed were NSOs’ conceptual orientation, structures, resources, capabilities and outcomes. Changing was unveiled through the interplay between three levels of analysis - wider political and economic, sport sector, and organisation-specific. The history of changing unfolded over a 25 years period and followed three stages of crisis of governability (1980-1989), crisis displacement (1989-1997) and identity search (1998-2004). Changing was determined by tensions generated in the previous socialist sport system, the new forces in the NSOs’ context, and by managers’ interpretation of events, and was a discovery process. The three NSOs followed different change patterns of shrinking, insulation and expansion. Two key reasons were responsible for those differences - the institualisation of the broader political and sport sector contexts, and NSOs’ choice to pursue narrow elitism (specialism) or the broader aims of sports development (generalism). The contextualist approach allowed us to appreciate the historical, contextual and processual nature of changing and to discuss the role of managers and various forces in shaping its course and outcomes

A list of websites and reading materials on strategy & complexity

The list has been developed based on a broad interpretation of the subject of ‘strategy & complexity’. Resources will therefore more, or less directly relate to ‘being strategic in the face of complexity’. Many of the articles and reports referred to in the attached bibliography can be accessed and downloaded from the internet. Most books can be found at amazon.com where you will often find a number of book reviews and summaries as well. Sometimes, reading the reviews will suffice and will give you the essence of the contents of the book after which you do not need to buy it. If the book looks interesting enough, buying options are easy

Dealing with Dutch Disease

This note looks at so-called Dutch disease, a phenomenon reflecting changes in the structure of production in the wake of a favorable shock (such as a large natural resource discovery, a rise in the international price of an exportable commodity, or the presence of sustained aid or capital inflows). Where the natural resources discovered are oil or minerals, a contraction or stagnation of manufacturing and agriculture could accompany the positive effects of the shock, according to the theory. The note considers channels through which such natural resource wealth can affect the economy. It also focuses on the development implications of Dutch disease, particularly the potential negative effects related to productivity dynamics and volatility; and concludes with a summary of possible policy responses, including the mix of fiscal, exchange rate, and structural reform policies.Dutch disease, shock, natural resources, comodities, capital, aid, oil, minerals, manufacturing, agriculture, wealth, volatility

JXTA-Overlay: a P2P platform for distributed, collaborative, and ubiquitous computing

With the fast growth of the Internet infrastructure and the use of large-scale complex applications in industries, transport, logistics, government, health, and businesses, there is an increasing need to design and deploy multifeatured networking applications. Important features of such applications include the capability to be self-organized, be decentralized, integrate different types of resources (personal computers, laptops, and mobile and sensor devices), and provide global, transparent, and secure access to resources. Moreover, such applications should support not only traditional forms of reliable distributing computing and optimization of resources but also various forms of collaborative activities, such as business, online learning, and social networks in an intelligent and secure environment. In this paper, we present the Juxtapose (JXTA)-Overlay, which is a JXTA-based peer-to-peer (P2P) platform designed with the aim to leverage capabilities of Java, JXTA, and P2P technologies to support distributed and collaborative systems. The platform can be used not only for efficient and reliable distributed computing but also for collaborative activities and ubiquitous computing by integrating in the platform end devices. The design of a user interface as well as security issues are also tackled. We evaluate the proposed system by experimental study and show its usefulness for massive processing computations and e-learning applications.Peer ReviewedPostprint (author's final draft
