Creating a Web 2.0 government: Views and perspectives

Over the last decade, the role played by governments has moved further away from direct service provision towards regulation and governance of services provided by a multiplicity of private and non-profit entities. Governments have put reform and innovation of the public sector into their programs, striving to deliver more efficient and effective public services, in order to meet the increasing expectations of citizens. An Information and communication technologies (ICT) has long been recognized as a key driver of government modernization. Undoubtedly, e-Government has been on the policy agenda for several years to support or redefine the existing and/or future (information, communication and transaction) relations with stakeholders in the internal and external environment in order to create added value. The common features of the reform agenda are a more citizen oriented and open government, better public sector performance, new forms of accountability and control, the use of market mechanisms and more decentralized. In virtue of the nature of Web 2.0, it is often presented as a revolutionary way of gathering, organizing and sharing of information and has much potential for the public sector in terms of interaction, participation and transparency. Despite the fact that a large number of people embrace Web 2.0, some critics also state that Web 2.0 is an exaggerated hype and raise the question whether the potential of Web 2.0 will be realized in practice. This paper focus on significance issues of Web 2.0 for e-Government: Are Web 2.0 applications relevant for the government context? If they are, in what way is Web 2.0 likely to have an impact on e-Government? How significant could this impact be? How is Web 2.0 applications implemented in the government context? and what are the expected opportunities and threats of Web 2.0 for the public sector?

From the bricks to the clicks: knowledge management in e-government

Today the expression of electronic government (e-government) is a synonym for a modern and efficient administration, and goes well beyond providing constituents with government information and services by leveraging information and communication technologies (ICT). The desired goal is that of convergence characterized by ubiquitous access to government information and services and total transparency of government functioning. Over the past several years, there has been unprecedented change in the way that volumes of data, information and knowledge is created, stored, disseminated and used. Over this period, there have been significant steps forward in governments information management, and there are plenty of examples of good progress in specific areas. These show improvements can be made with effective leadership and management, and they provide experience that can be used more widely. Knowledge management (KM) is a distinct contribution of the private sector as a competitive advantage and knowledge capital hold the sway. It is only recently that KM has started making entry to public sector. One of the reasons for this development has been the emergence of ICT and knowledge worker in the knowledge economy. To deliver more innovative services to demanding public, governments must be involved in the deployment of such new services as e-government and e-commerce. The challenge for e-government is to find a successful way of re-engineering and distributing the administrations knowledge and active management of their knowledge assets is mandatory for success. This paper discusses the KM for e-government development in significance and role, and addresses the KM key issues, activities and questions whether the KM approach that has proven to be successful in business environment is applicable to the provision of public sector services.

Secure Site Authentication and Message Transmission Based on Grid Environment

Grid computing architecture was defined to be a complete physical layer. Data transfer in network must be in secure. In this study, encryption and decryption algorithms of a site authentication and its message are developed and applied in each grid node to ensure secure transmitted information. If the site information has been built in supervisor node then it can receive data sent from other grid nodes in safety as well. Message processing can be kept in secure for all systems when these algorithms are installed in all nodes.

Modernizing Government: Reengineering through Knowledge Management Approach

Knowledge management (KM) in electronic government (e-government) is a critical factor for e-service delivery and it has always been a constant concern in public administrations. Many information and communication technology (ICT) enabled applications of KM have become available to support policy development and implementation tasks. Plans to modernize government processes and practices are leading to a reconsideration of how to manage the vast range of knowledge resources that are found within the public sector. Much of the work in the public sector revolves around the use and interpretation of information and knowledge. With the quantity and multiplicity of types of information being held and used within the public sector, managing knowledge is a difficult task. One consequence of this is that concepts of KM are increasingly being applied. Today in response to the changes in globalization, growing customer demands and increasing ICT possibilities the public sector adapts approaches that have proven to be successful in business environment. The paper addresses the KM key issues, activities and questions whether the KM approach that has proven to be successful in business environment is applicable to the provision of modernizing government.

A Performance Optimization of Job Scheduling Model Based on Grid Environment

To achieve the best quality of overall optimal performance on grid environment and user services, job loads need to be balanced in grids due to the non-uniformly distributed nature of jobs submitted to grids. Jobs are transferred from a heavy loaded grid to other grids in order to achieve performance optimization. The running cost of a job is calculated at the time it is completed. In this paper, we propose a job schedule model considering job cost and performance. The algorithm is resided in all grids to schedule and arrange their own jobs by themselves to get best performance without extra user cost.
