    This project utilizes the naturally occurring phenomenon of plants and microbial bacteria to communicate, called "cross-talk", as a central approach in addressing humandominated landscape simplification. Through emitting Volatile Organic Compounds (VOCs) these organisms can provide one another with valuable information regarding nutrient and depredation sources and allow organisms to allocate their resources in a proactive and beneficial way. The purpose of this project is to demonstrate the design of an educational research center that can advance the knowledge of how to use natural design strategies based on biotic and abiotic processes, to advance our knowledge and efficiency of yield-producing constructed landscapes, and to explore design in relationship to natural processes. This project includes a proposal for the design of the Cooper/Skinner Sustainable Educational Center on the Cooper-Skinner site, Muncie, Indiana. Which has been designed to contribute to the understanding of the relationship of 1) human-dominated, landscape simplification, 2) cross-talk among organisms, and 3) the role of cross-talk in the management of the health and productivity of landscapes created via site-based processes of built landscape design. The Cooper/Skinner Sustainable Education Center is designed through the homogenization of constructed landscape grid and natural systems patterns to demonstrate the feasibility of human-dominated and natural systems integration. Furthermore, the Center educates individuals on landscape diversity, ecosystem services, and non-renewable inputs in relationship to constructed and industrialized landscapes. The site is designed through a series of diversifying and simplifying species gradients with VOC sampling transects running contiguous along these gradients. The sampling gradients, resembling top-down and bottom-up research methodologies, are then analyzed, comparing them to control samplings taken on-site. This project seeks to identify the threshold of plant and microbial bacteria species diversity required to provide natural systems with adequate complexity to be self-sustaining and capable of complexifying over time. Additionally, a series of introduced, ecologically diverse patches are proposed as an opportunity to learn about how components of living systems can provide valuable information useful for their fertilization, pollination, and protection of neighboring humansimplified landscapes. The hypothesis is that these introduced patches will extend the ecology found within the surrounding vegetative environments into the monocultural zone that is far less alive in terms of beneficial information exchange within the living system.Department of Landscape ArchitectureThesis (M.L.A.

    Estimating the Nonmarket Value of Green Technologies Using Partial Data Enrichment Techniques

    Recent studies have suggested that green technologies may be a cost effective way to manage urban runoff. Literature has also suggests that there needs to be a greater empirical basis to estimate the benefits associated with social values associated with urban trees; we therefore estimate ecosystem benefits of green technologies using emerging data enrichment valuation methods.Environmental Economics and Policy,

    Uncertainty and Human Capital Decisions: Traditional Valuation Methods and Real Options Logic

    Get PDF
    As the importance of human capital increases in organizations, so does the need to develop more sophisticated financial valuation models. This paper reviews some of the major traditional financial decision making models used in costing employment mode choices. It then introduces the real options valuation approach for costing such choices. The advantage of the real options model is demonstrated to build flexibility into employment decisions

    New Zealand culture of intoxication: Local and global influences

    Get PDF
    This article shows that attitudes towards and behaviours involving the consumption of alcohol in New Zealand have long been problematic. It provides an historical account of social, economic and legislative factors which have influenced the development of the New Zealand drinking culture. Accordingly, it tracks a combination of local and global alcohol-related influences and documents the interrelationships amongst these factors. In particular, it proposes that the liberalisation of alcohol licensing laws and advertising/sponsorship regulations, alongside the growth of the alcohol-based hospitality industry have promoted the normalisation of an alcohol-based leisure lifestyle. Against this backdrop, the growth of consumer culture , tertiary student culture and the New Zealand drug culture, along with the development of new alcohol products and the establishment of commercial and social-networking websites have conjointly enabled the growth of a culture of intoxication, which is characterised by drinkers intentionally drinking to intoxication and viewing this behaviour as socially acceptable

    REVENUE RISK AND FISHERY CHOICE WITH LINEAR-EXPONENTIAL UTILITY: AN APPLICATION TO BERING SEA/ALEUTIAN ISLANDS TRAWL FISHERIES

    Get PDF
    A discrete choice model of 1991-96 trawl groundfish fishery participation in the Bering Sea/Aleutian Islands region is developed and estimated. The model fits well, with strong risk and seasonal effects. Notably, the model uses routinely-collected data, suggesting this type of analysis can be a regular part of the management process.Resource /Energy Economics and Policy,
