An Experimental Test of Controls on Resource Exchange in an Ectomycorrhizal Mutualism
Models of resource exchange mutualisms utilize economic principles to explain how the costs and benefits of these interactions vary with environmental context. All of these models use a ratio of resource exchange (e.g., nitrogen: carbon) as the central variable, and it is unclear whether such …

Cooperation and Punishment in the Arbuscular Mycorrhizal Symbiosis: Implications for Resource Exchange & Biological Market Dynamics
… significance, the mechanisms that control the resource exchange between both partners in the arbuscular mycorrhizal symbiosis are largely unknown. The main aim of this research project is to better understand the physiological mechanisms that control the cost to benefit ratios in the AM …

Genetic And Temporal Variation In Resource Exchange Between An Ectomycorrhizal Fungus, Rhizopogon Occidentalis, And Seedlings Of Pinus Radiata
… to explain the evolutionary persistence of resource exchange mutualisms such as mycorrhizae. The ratio of resources exchanged is an important variable comto all these models. Measuring resource exchange ratios is the first step in testing the hypotheses predicted by these models and will …

Addressing Trans-boundary Challenges Through Collaboration: How Organizations "Harmonize" Actions and Decisions Across Problem Landscapes
… policy-related benefits of collaboration: 1) resource access/exchange, 2) innovation generation, 3) coordinated action, 4) working relationships built through social capital, and 5) reduction/resolution of conflict. A rich empirical dataset was developed to explore these benefits, utilizing …

Small Business Crews As High Performance Work Teams: The Role Of Vertical And Horizontal Familiarity
… role theory (Foa & Foa, 1974), leader-member exchange (Graen & Scandura, 1984) and team-member exchange (Seers, 1989) theories, within Grant's (2007) relational job design model, a conceptual model is developed and then empirically tested. It is proposed that through vertical team familiarity …

A reliability-based measurement of interoperability for conceptual-level systems of systems
… thesis is the development of the Architectural Resource Transfer and Exchange Measurement of Interoperability for Systems of Systems, or ARTEMIS methodology. ARTEMIS first outlines a quantitative measurement of system pair interoperability using reliability in series and in parallel. This step …

Central government instruments of influence upon services delivered by local government
… an "agent" of the centre, nor one of near equal "resource exchange" or "bargaining" between central and local actors. Rather, through use of instruments of influence in a plurality of permutations, the centre can set constraining parameters unilaterally - instead of having to react to pressures …

Influence of Personal and State Level Variables on Perception of State Emergency Management Network Resilience In 47 States
… role and function, entities need to be able to exchange resources and information with each other, often under time, economic, or other constraints during disasters. This resource exchange generates trust, an essential element of a resilient network. Resilient networks suffer fewer negative …

THE ECOLOGICAL IMPORTANCE AND EVOLUTIONARY POTENTIAL OF PHENOTYPIC PLASTICITY IN NOVEL ENVIRONMENTS
… lines from the Drosophila Synthetic Population Resources to examine genetic architecture in historical and novel alcohol environments. The first two chapters focused on plastic responses to abiotic environments, about which we have a wealth of theoretical and empirical understanding. Natural …

Explaining Technological Change of Wind Power in China and the United States: Roles of Energy Policies, Technological Learning, and Collaboration
… in integrating wind power because it allows resource pooling and optimal allocating of the resources by the central network administrative agency (NAO). The case study also suggests an alternative path to improved network effectiveness for a less cohesive network, which is through more …

Spectrum-efficient Cooperation and Bargaining-based Resource Allocation for Secondary Users in Cognitive Radio Networks
… between the secondary user and its relay as a resource exchange process, where the secondary user vacates part of its dedicated free spectrum access time to the relay as a price for the energy consumed by the relay in forwarding the secondary user's packets. We define a suitable utility …
