    The marine protected area planning process in Washington state: Recommendations for increased effectiveness

    Get PDF
    In Washington State, the Department of Natural Resources (WA DNR) is responsible for managing state-owned aquatic lands. Aquatic reserves are one of many Marine Protected Area (MPA) designations in WA State that aim to protect sensitive aquatic and ecological habitat. We analyzed the designation and early planning processes of WA State aquatic reserves, identified gaps in the processes, and recommend action to improve the WA State aquatic reserve early planning approach.

    Theory underlying the peripheral vision horizon device

    Get PDF
    Peripheral Vision Horizon Device (PVHD) theory states that the likelihood of pilot disorientation in flight is reduced by providing an artificial horizon that provides orientation information to peripheral vision. In considering the validity of the theory, three areas are explored: the use of an artificial horizon device over some other flight instrument; the use of peripheral vision over foveal vision; and the evidence that peripheral vision is well suited to the processing of orientation information

    Money

    This essay, written around 1779, challenges the simple quantity theory of money. From the perspective of the paper money issued to pay for American's Revolutionary War--bills of credit, or continentals -- the essay rejects the idea that the value of money is determined by the number of pieces of paper issued. That idea ignores the fact that an individual nation is just a small part of the world economy. More relevant than quantity, the essay argues, are two other features: the date the government promises to exchange the pieces of paper for specie and the credibility of that promise. This essay originally appeared in a 1791 Philadelphia newspaper. The version reprinted in this journal is the edited and annotated version from The Papers of James Madison (Chicago: University of Chicago Press, 1962).

    Efficient Video Indexing on the Web: A System that Leverages User Interactions with a Video Player

    Full text link
    In this paper, we propose a user-based video indexing method, that automatically generates thumbnails of the most important scenes of an online video stream, by analyzing users' interactions with a web video player. As a test bench to verify our idea we have extended the YouTube video player into the VideoSkip system. In addition, VideoSkip uses a web-database (Google Application Engine) to keep a record of some important parameters, such as the timing of basic user actions (play, pause, skip). Moreover, we implemented an algorithm that selects representative thumbnails. Finally, we populated the system with data from an experiment with nine users. We found that the VideoSkip system indexes video content by leveraging implicit users interactions, such as pause and thirty seconds skip. Our early findings point toward improvements of the web video player and its thumbnail generation technique. The VideSkip system could compliment content-based algorithms, in order to achieve efficient video-indexing in difficult videos, such as lectures or sports.Comment: 9 pages, 3 figures, UCMedia 2010: 2nd International ICST Conference on User Centric Medi

    Baby Boomers & adult Ageing: Issues for Social and Public policy

    Get PDF
    This paper provides a critical assessment of academic and policy approaches to population ageing with an emphasis on the baby boomer cohort and constructions of late-life identity. It is suggested that policy towards an ageing population has shifted in focus, away from particular social hazards and towards an attempt to re-engineer the meaning of legitimate ageing and social participation in later life. Three themes are identified: constructing the baby boomers as a force for social change, a downward drift of the age associated with 'older people' and a shift away from defining ageing identities through consumption, bacl towards work and production. The paper concludes with a discussion of the implications for future social and public policy
