زمینه: احتکار به عنوان ذخیره و پنهان کردن چیزی برای مصرف احتمالی آن در آینده تعریف می شود. این رفتار دارای ابعاد مختلفی بوده که شامل رفتار تطابقی در حیات وحش، احتکار اقتصادی جامعه انسانی و از سویی بخش روانی آن ( مثل احتکار حیوان و اشیاء بی ارزش) که زیر گروهی از اختلال وسواس اجباری بوده؛ می شود. ریشه احتمالی مشترک تمام انواع احتکار، وجود یک شرایط محرومیت است. در مدل آزمایشگاهی احتکار، برای همانن...

Among the important challenges facing water resources of the country, one can mention the phenomenon of climate change and its impacts. The General Circulation Models (GCMs) can provide the best information about the response to increasing the concentration of greenhouse gases. Since the outputs of this model do not have sufficient time and space accuracy for studies on the effects of climate c...
