    Temporal Insensitivity of Willingness to Pay: How do they evaluate in CVM?

    Get PDF
    In addition to scope and scale embedding effects, temporal insensitivity of willingness to pay, also known as temporal embedding effect, has been a well known anomaly in eliciting willingness to pay for environmental quality change, especially over time. Stevens et al. (1997) defines two types of temporal embedding effects: strong insensitivity and weak insensitivity to payment schedule. This paper proposes an alternative definition of the temporal insensitivity. Temporal insensitivity implies that a subject in the survey responds consistently to value elicitation questions regardless of payment schemes. The sequential test tests the temporal insensitivity using the oyster reef restoration programs in Chesapeake Bay. Test results show that willingness to pay for the program is insensitive to the payment scheme or to the length of benefit stream of the project. Discount rates imbedded in cost stream vary significantly among the combination of project lengths and payment schemes.Temporal insensitivity of willingness to pay, Temporal embedding effect, Implicit discount rate, Sequential test, Demand and Price Analysis,

    Customized television: Standards compliant advanced digital television

    This correspondence describes a European Union supported collaborative project called CustomTV based on the premise that future TV sets will provide all sorts of multimedia information and interactivity, as well as manage all such services according to each user’s or group of user’s preferences/profiles. We have demonstrated the potential of recent standards (MPEG-4 and MPEG-7) to implement such a scenario by building the following services: an advanced EPG, Weather Forecasting, and Stock Exchange/Flight Information

    Influences on Throughput and Latency in Stream Programs

    Vu Thien Nga Nguyen and Raimund Kirner, 'Influences on Throughput and Latency in Stream Programs' paper presented at the 2nd Workshop on Feedback-Directed Compiler Optimization for Multi-Core Architectures. Berlin, Germany. 22 January 2013Stream programming is a promising approach to execute programs on parallel hardware such as multi-core systems. It allows to reuse sequential code at component level and to extend such code with concurrency-handling at the communication level. In this paper we investigate in the performance of stream programs in terms of throughput and latency. We identify factors that affect these performance metrics and propose an efficient scheduling approach to obtain the maximal performance

    Hybridizing old downtown Suwon City: how new urban fabric may save the past

    Get PDF
    In response to paradigm shifts of environmental, social and economic methods at the local and global scales, new approaches are required for creating alternative urban models which emphasize sustainability and landscape productivity. The Old Downtown of Suwon City, South Korea, which is encompassed by the Hwaseong Fortress and designated by UNESCO as a World Heritage Site, is currently experiencing challenges between preservation and development – past and future. This thesis investigates sustainable and productive urban tactics to mediate this conflict. The primary focus of these tactics is the re-organization of land use towards more efficient and productive models born of contemporary science, technology, and culture, while simultaneously embracing and preserving key aspects of the city’s heritage

    Guidelines for the Provision of Garbage Reception Facilities at Ports Under MARPOL Annex V

    Get PDF
    This report offers guidelines for the provision of adequate port reception facilities for vessel-generated garbage under the requirements of Annex V of the International Convention for the Prevention of Pollution From Ships, 1973 (MARPOL 73/78), Regulations for the Prevention of Pollution by Garbage from Ships. MARPOL Annex V prohibits at-sea disposal of plastic materials from vessels, and specifies the distance from shore at which other materials may be dumped. Annex V also requires the provision of port reception facilities for garbage, but it does not specify these facilities or how they are to be provided. Since the at-sea dumping restrictions apply to all vessels, the reception facility requirement applies to all ports, terminals, and marinas that serve vessels. These guidelines were prepared to assist port owners and operators in meeting their obligation to provide adequate reception facilities for garbage. The report synthesizes available information and draws upon experience from the first years ofimplementation of MARPOL Annex V. (PDF file contains 55 pages.

    A Primer for Monitoring Water Funds

    Get PDF
    This document is intended to assist people working on Water Funds to understand their information needs and become familiar with the strengths and weaknesses of various monitoring approaches. This primer is not intended to make people monitoring experts, but rather to help them become familiar with and conversant in the major issues so they can communicate effectively with experts to design a scientifically defensible monitoring program.The document highlights the critical information needs common to Water Fund projects and summarizes issues and steps to address in developing a Water Fund monitoring program. It explains key concepts and challenges; suggests monitoring parameters and an array of sampling designs to consider as a starting-point; and provides suggestions for further reading, links to helpful resources,and an annotated bibliography of studies on the impacts that result from activities commonly implemented in Water Fund projects
