Grid computing enables computers on different networks to share their resources in an organized way. Authorized users can deploy the resources as if they were in the same organization. This resource sharing environment is called a Virtual Organization (VOs). To enable an open Grid to support resource sharing between multiple heterogeneous VOs, an authorization policy management framework is required to support authorization for VOs using heterogeneous authorization systems. The challenges include dynamic Grid memberships, VO trust relationships, and heterogeneous authorization systems. / To solve these problems in a loose-coupling way, we propose a dynamic, distributive and heterogeneous authorization policy management framework. The framework is called Dynamic Policy Management Framework (DPMF). DPMF groups VOs of the same authorization systems to form a virtual cluster. Authorization policy management is divided into inter-cluster heterogeneous policy management, and intra-cluster homogeneous policy management. Inside a virtual cluster, the workloads of policy management can be distributed among the VOs according to their trust relationships. The Conflict Analysis with Partial Information (CAPI) mechanism is developed to make authorization decisions in open environments without complete policy information. A Heterogeneous Policy Management mechanism is developed for DPMF to support inter-cluster heterogeneous policy management. / Traditional authorization policy management frameworks work well in authorization for a single VO where the participating hosts agree to follow a global authorization system. However, they are not capable of authorization policy management for multiple VOs which deploys heterogeneous authorization systems. / Yu, Chiu Man. / "April 2007." / Adviser: Ng Kam Wing. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0447. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 200-206). / Electronic reproduction.

Foam fighting is a form of Live Action Role Playing (LARP) that focuses on mock combat and recreational battle, with role-playing aspects taking a less prominent role. It is sometimes referred to as a “poor man’s martial art”.While there does not appear to be any clear documentation concerning the origins, research on foam fighting suggests the sport began in Maryland in the 1970’s and slowly spread throughout the United States. This research will illustrate how the sport of foam fighting demands a level of critical thinking that takes both the participant and audience beyond the sight of a swinging stick. I plan to show how this sport provides an outlet for high levels of creativity, social interaction and strategic planning skills. It is a hobby that has had a great impact on the daily lives of many of its participants and continues to grow and evolve. / Includes bibliography. / Thesis (M.F.A.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

The constant evolution of technology and the prevalent demands of the 21st century continue to put pressure on both the business and education sector. Business is ever looking for competent workers to meet these progressive demands, while the education sector continues to struggle to produce such competent workers to meet the heightened needs of the business sector. Universities and business schools have a greater role and responsibility in ensuring that these competent employees are produced. The use of virtual platforms like Second Life has gained significant popularity in the education sector. Therefore the objective of this study was to explore and examine some of the prevalent benefits associated with using Second life for teaching entrepreneurship. This study was also extended to cover the following areas: The benefits of Second Life for business and education sector; - The benefits of Second Life for teaching and learning environment. The study followed an exploratory research design in an attempt to answer the main research question and the respective sub-questions related to the study. Using a qualitative approach, student’s perceptions, opinions, assumptions, observations and experiences during their interaction with Second Life were identified and reflected in the study. The research discovered that the associated benefits of Second Life were coherent with the reviewed literature findings. The research study concluded that Second Life can be used as a support teaching methodology for entrepreneurship for third year MBA students at NMMU Business School. In addition, the research also highlighted some recommendations regarding the introduction and implementation of Second Life at NMMU Business School and future research opportunities.
