چکیده اساسی ترین منبع استراتژیک هر سازمان یا جامعه،منابع انسانی می باشد.جوامع موفق،جوامعی هستند که بتوانند منابع انسانی خود را به طور صحیح پرورش و توسعه دهند. در اقتصاد امروز، دانش به عنوان مهمترین سرمایه، جایگزین سرمایه مالی و فیزیکی شده است . دانش و اطلاعات به رشد اقتصادی کمک می کند.این امر موجب افزایش اهمیّت سرمایه فکری به عنوان مقوله ای پژوهشی شده است. مدیریت منابع انسانی یعنی مدیریت و ادار...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
In recent years, steps have been taken to implement a new crop insurance program for rangeland and pasture. Unlike traditionally insured row and cereal crops, which have directly measurable yields, there is no such simple, ideal yield standard for rangeland and pasture because of uncertainties regarding how to generally and objectively quantify annual production. With remotely sensed imagery ac...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Adaptive management is an approach to natural resource management that uses structured learning to reduce uncertainties for the improvement of management over time. The origins of adaptive management are linked to ideas of resilience theory and complex systems. Rangeland management is particularly well suited for the application of adaptive management, having sufficient controllability and redu...
Significant efforts are underway to translate improved understanding of how climate change is altering ecosystems into practical actions for sustaining ecosystem functions and benefits. We explore this transition in California, where adaptation and mitigation are advancing relatively rapidly, through four case studies that span large spatial domains and encompass diverse ecological systems, ins...
Abstract. The present research aims to identify and analysis the effectiveness of rangeland management cooperatives in Gonbad city. The study was conducted in 2015. The research was performed in descriptive manner as survey method. The subjects (participants) included all members of rangeland management cooperative in Gonbad city. The sample size was determined by Cochran (n=200). For sampling ...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
Oklahoma is blessed with an abundance of excellent forage resources. Many Oklahoma producers enjoy the benefits of operating livestock production systems on both rangeland and introduced-forage pastures. However, some producers may not be aware of the need for different management strategies for the two ecosystems. Improper management generally results in decreased profitability of the livestoc...
The adoption and adaptation of enclosures in the arid and semi-arid rangelands of sub-Saharan Africa is driven and sustained by a combination of factors. However, reviews indicate that these factors cannot be generalized, as they tend to be case specific. A study was therefore conducted to explore the history and reasons for enclosure establishment in Chepareria, a formerly degraded communal ra...
