Spacecraft design project: Low Earth orbit communications satellite
This is the final product of the spacecraft design project completed to fulfill the academic requirements of the Spacecraft Design and Integration 2 course (AE-4871) taught at the U.S. Naval Postgraduate School. The Spacecraft Design and Integration 2 course is intended to provide students detailed design experience in selection and design of both satellite system and subsystem components, and their location and integration into a final spacecraft configuration. The design team pursued a design to support a Low Earth Orbiting (LEO) communications system (GLOBALSTAR) currently under development by the Loral Cellular Systems Corporation. Each of the 14 team members was assigned both primary and secondary duties in program management or system design. Hardware selection, spacecraft component design, analysis, and integration were accomplished within the constraints imposed by the 11 week academic schedule and the available design facilities
Australian real estate management and development companies and women directors
Purpose – There is a large literature advocating the importance of a greater proportion of women directors on boards of publicly listed firms. The purpose of this paper is to examine the numbers and proportions of women directors, including women executive directors, on listed Australian Real Estate Management and Development (REMD) companies to identify how prevalent women directors are on such boards. Design/methodology/approach – The study examines the numbers and proportions of women directors for 35 REMDs in 2011 and compares this to the broad board composition data on 1,715 Australian Stock Exchange listed entities. Statistically significant findings are evident due to the identified low proportions. Findings – The study finds that of all the Financials Sub Industry sector groups, REMDs have the lowest proportion of female directors on theirs boards – eight women on each of 35 company boards compared to 159 men on these 35 boards at 2011. Of the eight, there were only two women executive directors on boards compared to 50 men. Statistically, it appears that having women directors on REMD boards is not considered important. Even at December 2014, there are only ten women on seven company boards and only one remaining executive director of an REMD company. Practical implications – Given that female board representation is positively related to accounting returns and that there is a growing voice for legislation to impose mandatory proportions of women directors on boards around the world, it may be in the interests of REMD boards to consider appointing more women more quickly. Originality/value – The study is the first to examine the numbers and proportions of women directors amongst REMD companies to identify the paucity of such women directors
Eliciting the implicit knowledge and perceptions of on-ground conservation managers of the Macquarie Marshes
Knowledge that has been developed through extensive experience of receiving and responding to ecological feedback is particularly valuable for informing and guiding environmental management. This paper captures the implicit understanding of seven experienced on-ground conservation managers about the conservation issues affecting the Ramsar listed Macquarie Marshes in New South Wales, Australia. Multiple interviews, a workshop, and meetings were used to elicit the manager's knowledge. The managers suggest that the Macquarie Marshes are seriously threatened by a lack of water, and immediate steps need to be taken to achieve more effective water delivery. Their knowledge and perceptions of the wider societal impediments to achieving more effective water delivery have also led the managers to suggest that there may be system feedbacks that are reinforcing the tendency for water agencies to favor the short-term interests of the irrigation industry. Although the managers clearly have certain personal interests that influence their understanding and perceptions, much of their knowledge also appears to have been heavily influenced by their ecological understanding of the wetland's dynamics. This paper highlights that although all stakeholders clearly need to be involved in making decisions about conservation and how resources should be used, such decisions should not be confused with the need for consulting people with the appropriate ecological expertise to help determine the degree to which an ecological system is threatened, the likely ecological causes of the threats, and actions that may be needed to restore and maintain a functional ecosystem
The Open Navigation Surface Project
Many hydrographic and oceanographic agencies have moved or are moving towards gridded bathymetric products. However, there is no accepted format to allow these grids to be exchanged while maintaining data and metadata integrity. This paper describes the Open Navigation Surface (ONS) Project, which aims to fill this gap. The ONS Project is an open-source software project designed to provide a freely available, portable source-code library to encapsulate gridded bathymetric surfaces with associated uncertainty values. The data file format is called a Bathymetric Attributed Grid (BAG). The BAG is developed and maintained by the ONS Working Group (ONSWG), and the source code is available via the ONS websit
