Self-Organized Public-Key Management for Mobile Ad Hoc Networks Based on a Bidirectional Trust Model

In traditional networks , the authentication is performed by certificate authoritys（CA）,which can＇t be built in distributed mobile Ad Hoc Networks however. In this pa per, we propose a fully self-organized public key management based on bidirectional trust model without any centralized authority that allows users to generate their public-private key pairs, to issue certificates, and the trust relation spreads rationally according to the truly human relations. In contrast with the traditional self-organized public-key management, the average certificates paths get more short, the authentication passing rate gets more high and the most important is that the bidirectional trust based model satisfys the trust re quirement of hosts better.

Hanoi Public TransportmTransformation by Management Using Action Research and Behavior Setting Theory

After the economic reforms in Vietnam, the number of motorbikes surged while public transport lost its passengers. No funds for investment available TRAMOC （Transport Management and Operation Centre）, the Transport Management and Operation Center started the experiment of transforming Hanoi Public Transport by management based on action research, introducing some interventions, which had shown to be effective in Europe. Phase I of the experimental approach was carried out with the smallest company that operated Line 32. The number of daily passengers surged from 1,700 to 8,000. In Phase II, the experiment was extended to the whole net. In 2001, there were 35,000 passengers per day, in 2010, there were 1 million; this is an increase of 3,000%. The result surpassed by far the expectations. The key for understanding the surprising results is the mode choice. 53% of the users are riders by choice; they have access to a car or motorbike. Simulation of the decisions as rational choice based on time needed for trips was proved to be quite accurate. Behavior was analyzed in the frame of behavior setting theory, which brings together urban structure and the design of the transport system. Success with introducing public transport needs a self-reliant leadership, which works with people in their real life situation. An urban transport system is part of the organized behavior of the people, who make use of the technical opportunities offered.

The Mixed Mechanism in the Management of Water Resources in China

It is a challenge for China to address its serious water resource problems, and inefficient water use. Improving water use efficiency is the key solution to dealing with this issue. There are two basic mechanisms practiced in the world aiming to pursue water conservation, i.e. administrative and market-based management pattern. Water as an irreplaceable resource with many attributes, either public or market-based management mechanism has its disadvantages. In order to avoid the inherent "administrative failure" or "market failure", this paper emphasizes the importance of changing traditional water resource management mechanism to establish a mixed mechanism of public and market water management based on China’s conditions and experiences from developed countries. Three key aspects of this combined mechanism are identified in this paper, i.e. recognizing and managing water rights to promote efficiency, strengthening effectiveness of government management to lower transaction cost and encouraging water user participation to increase flexibility. Detailed information on implementing of this combined mechanism in China is given in the end.

Understanding Interoperability in Collaborative Network Management： the Case of Metro High School

The-increasing importance of interoperability （IOp）--reciprocal communication and accommodation among government organizations and NGOs to develop interactive policy and programming--has become an integral part of networked organizations, now utilized beyond IOps＇s emergency management origins in public administration. Using a mixed methods approach, this paper empirically examines IOp in a networked STEM （science, technology, engineering and mathematics） secondary school that includes 16 school districts and their public agency and NGO partners, particularly in its planning and operational phases. It also identifies the growing use of lOp in a number of non-emergency management settings and raises the prospects for utilizing this type of interorganizational management in the public arena.

Managing Public Relationships via Corporate Blogs

Content analyses of corporate blogs of large Korean firms over two years in a longitudinal design revealed that relationship management strategies of openness, positivity and sharing of tasks were featured relatively strongly, whereas networking, access, and assurances were enacted relatively weakly. Further, most Korean corporate blogs utilized a tightly controlled top-down strategy. In addition, the use level of relationship management strategy was tied to the kind of corporate blogging strategies, but not to the industry type of the firms. Although utilized the same social media device, corporate blogs enacted different purposes and relational management activities in different countries, indicating that corporate blogs are largely cultural and driven locally.

Selection of IT Sourcing Alternatives in Public Sector Using the Analytic Hierarchy Process

Recent research carried out in the public sector shows that outsourcing can indisputably bring many benefits to the organizations which master the art of devising, deploying and maintaining outsourcing relationships. However, for many organizations, these benefits remain elusive, while outsourcing projects are usually accompanied by unexpected and often negative effects. The paper focuses on in-depth analysis of the current situation concerning outsourcing of information technology projects （IT-projects） in Slovenian public sector. Presented research initially analyses substantive, procedural and other relevant aspects of outsourcing and provides a set of applicable decision making criteria. Stemming from the analysis results, this paper eventually presents the development of a multi criteria decision-support model based on Analytic Hierarchy Process （AHP） which could facilitate enhanced evaluation, selection and implementation of IT outsourcing projects in the public sector.

The Impact of Lean Transformation on the Organizational Performance: The Case of Public Utilities in Greece

Purpose: Lean Management concerns a strategy or philosophy aiming at saving resource practices and curtailment of public expenses, with ultimate objective of the enhancement of the organizational performance. By extension, the successful integration of the Lean Management leads to positive organizational results, such as higher quality, along with improved financial, environmental and business market performance. Although a lot of studies related to the effect of Lean production on the organizational performance have been conducted, empirical findings that examine the case of the public sector are absent. Additionally, there is no precise mechanism through which the Lean Management determines the organizational performance of the public utility companies. The above mentioned research gap is examined with this research, given that it investigates the influence of the Successful Lean Management on the Organizational Performance (Environmental Performance, Financial Performance, Business Performance) in public utilities in Greece. Research Methodology: The research method combines bibliographic research and empirical—with quantitative method—through a case study. More specifically, via quantitative approach, which was based on sample research with standardized questionnaire, performed in two of the biggest and most important public utilities in Greece, the Public Power Corporation S.A. (PPC S.A.) and the Athens Water Supply and Sewerage Company (EYDAP S.A). Findings: Quantitative findings from this illustrated that the successful transformation towards the Lean principles/saving resources affects positively the Business Market Performance, the Environmental and the Financial Performance. Limitations: Main restrictions of the current study are the capitalization of random sample and the strict focus on Greek public utilities that function under conditions of competition. Consequently, whichever generalizations for the whole Public Sector as well as for businesses of the private sector it would be better to be avoided, as they differ concerning their structural and functional features and their organizational culture.
