the first step in policy making is describing the objectives and choosing the policy instruments and management strategies and then, analyzing and assessing the impacts of them. in this study, farmers’ responses to selected policy instruments and management strategies were assessed using a semi-distributed planning model in qazvin irrigation and drainage network. the proposed model, simulates t...

In this paper, the eigenfunction expansion method combined with local contact models are presented to analyze repeated impact behaviors between sphere and beam. The simulations verified experimental results of a simply-supported beam struck 91 times by sphere. order clarify validity solve transverse impacts on beams, simulation spring-mass also compared experiments. It shows that appropriate mo...

Events in a sequence may each be evaluated as good or bad. We propose that such good-bad evaluations evoke emotional responses that change current mood. A model of recurrent updating of current mood is developed and compared to a model of how a sequence of events evoking emotional responses is evaluated retrospectively. In Experiment 1, 149 undergraduates are presented sequences of lottery outc...

In seeking to determine whether climate change mitigation strategies are effective, researchers and policy-makers typically use energy consumption as an indicator. UK government data shows that energy use amongst the public is rising, despite measures to encourage energy conservation. Yet, research to date has not explicitly asked which actions the public are taking with the express intention o...

OBJECTIVES Whiplash injuries from vehicle collisions are common and costly. These injuries most frequently occur as a result of a rear impact and, compared to males, females have up to twice the risk of whiplash-associated disorders (WAD) resulting from vehicle crashes. The present study focuses on the differences in the dynamic response corridors of males and females in low-severity rear impac...

Clinical empathy, which is defined as the ability to understand the patient's experience and feelings from the patient's perspective, is acknowledged to be an important aspect of quality healthcare. However, how work experience modulates the empathic responses and brain activation patterns in medical professions remains elusive. This fMRI study recruited one hundred female nurses, who varied th...

The addition of supplemental fatty acid (FA) sources to diets is a common practice in dairy nutrition to increase dietary energy density and to support milk production. The ability to understand and model FA, the effects of individual FA, and different FA supplements on production parameters has direct impact on dairy industry recommendations and the usefulness of FA supplementation strategies....

in recent years, virtual communities have been significantly popular and almost all of them are targeted for business profitability. in our study, the profitability of these communities for businesses has been analyzed from a commercial perspective. the study considers virtual community as a business model which can have a great impact on consumer purchase decision process. with respect to refe...
