A grant requesting $100k in direct costs with an indirect cost rate of 50%, for example, means that the request will include an additional request for $50k for indirect costs for a total request of $150k, as opposed to a request for $100k of indirect costs for a total request of $200k.
Direct reciprocity was proposed by Robert Trivers as a mechanism for the evolution of cooperation. [1] If there are repeated encounters between the same two players in an evolutionary game in which each of them can choose either to "cooperate" or "defect", then a strategy of mutual cooperation may be favoured even if it pays each player, in the short term, to defect when the other cooperates.
Ecosystem valuation is an economic process which assigns a value (either monetary, biophysical, or other) to an ecosystem and/or its ecosystem services.By quantifying, for example, the human welfare benefits of a forest to reduce flooding and erosion while sequestering carbon, providing habitat for endangered species, and absorbing harmful chemicals, such monetization ideally provides a tool ...
In construction, the costs of materials, labor, equipment, etc., and all directly involved efforts or expenses for the cost object are direct costs. In manufacturing or other non-construction industries, the portion of operating costs that is directly assignable to a specific product or process is a direct cost.
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
To construct an optimality model, the behavior must first be clearly defined. Then, descriptions of how the costs and benefits vary with the way the behavior is performed must be obtained. [1] Examples of benefits and costs include direct fitness measures like offspring produced, change in lifespan, time spent or gained, or energy spent and gained.
The failure to halt terrestrial biodiversity loss between 2000 and 2010 was estimated to cost the global economy $500 billion. [55] Continued biodiversity loss and environmental degradation poses a long-term risk to society and the economy, such as by increasing the risk of pandemics, floods, and droughts.
Most true cost accounting studies try to reveal hidden costs relate to the field of food and agriculture. The scope of these studies differs depending on the research question being addressed, the geographical coverage and the hidden impacts to be included in the analysis. There are many hidden impacts and some are difficult to measure or quantify.
