to evaluate the effects of sowing density, deferred harvesting, and harvest intensity on forage yield and an some vegetative characteristics of annual medic (medicago scutelatta var robinson) an experiment was conducted on the research farm of college of agriculture ,university of tehran ,karaj, during 2005 growing season. the expremental treatments were arranged in split-split plots based on a...

This article presents a practical tool for optimally scheduling wine grape harvesting operations taking into account both operational costs and grape quality. We solve a mixed-integer linear programming model to support harvest scheduling, labor allocation, and routing decisions. A quality loss function is used to represent wine quality reduction at each vineyard block due to premature or defer...

Using a bioeconomic model of the cod (Gadus morhua) and capelin (Mallotus villosus) fisheries of the Barents Sea, this study assesses the role of the fishermen’s behavior in reducing or intensifying the effects on the stocks caused by altered population dynamics. The analysis focuses on the economic development of the fisheries employing a profitmaximizing harvesting strategy over a given numbe...

Despite the importance of dispersal for population connectivity, dispersal is often costly to the individual. A major impediment to understanding connectivity has been a lack of data combining the movement of individuals and their survival to reproduction in the new habitat (realized connectivity). Although mortality often occurs during dispersal (an immediate cost), in many organisms costs are...

CONTEXT Many ambulatory care facilities do not have resources to provide same-day care for all walk-in patients. Yet, there are few guidelines that identify patients for whom care can be safely deferred. OBJECTIVE To describe the development and implementation of deferred-care guidelines for adults with musculoskeletal complaints. DESIGN Consensus process and field test. GUIDELINE DEVELOPME...

Deferred imitation of object-related actions (e.g., picking up a cloth with a set of tongs) was assessed in 3 enculturated juvenile orangutans (Pongo pygmaeus) and 3 enculturated juvenile chimpanzees (Pan troglodytes). For each task, animals were given 4 min to explore the objects (baseline), followed by a demonstration of the target behavior, and 10 min later, were re-presented the objects (de...

The deferred acceptance algorithm is often used to allocate indivisible objects when monetary transfers are not allowed. We provide two characterizations of agent-proposing deferred acceptance allocation rules. Two new axioms, individually rational monotonicity and weak Maskin monotonicity, are essential to our analysis. An allocation rule is the agent-proposing deferred acceptance rule for som...
