abstract prediction of death anxiety on the basis of demographic characteristics and sp پیش بینی اضطراب مرگ براساس ویژگی های دموگرافیک و مولفه های معنویت در سالمندان به کوشش الهام حسن زهی معنویت از جمله مفاهیمی است که سالیان متمادی در حوزه روان شناسی جایگاه خود را یافته است پیشینه پژوهش نشان داده است که با متغیرهای فراوانی در روانشناسی در ارتباط بوده است. هدف از پژوهش حاضر این اس...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Recent infrasound observations and related research work in long-range sound propagation indicate that fine-scale atmospheric inhomogeneities contribute to refraction, scattering, and related phenomena that can result in anomalous infrasonic arrivals. Gravity waves, in particular, have been shown through physics-based modeling to be responsible for infrasonic arrivals, at regional ranges, that ...
Hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. One of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. The indices which are calculated with the help of radiosonde...
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
A weather balloon and its suspended instrument package behave like a pendulum with a moving pivot. This dynamical system is exploited here for the detection of atmospheric turbulence. By adding an accelerometer to the instrument package, the size of the swings induced by atmospheric turbulence can be measured. In test flights, strong turbulence has induced accelerations greater than 5g, where g...
GPS radio occultation technique has been developed resulting from remote sensing applications in planetary atmospheric limb sounding pioneered by JPL and Stanford University in 1960s. Since the launch of the experimental satellite MicroLab1 on April 3 1995, the primary results from this Low Earth orbiter (LEO) satellite demonstrated potential scienti:c values and practical signi:cance of this i...
the construct of self-efficacy has received increasing attention in research over the past two decades. many studies have been carried out 1.3 significance of the study this study has pedagogical implications since improving students’ self- efficacy and autonomy is important for promoting actual performance on classroom academic tasks. in academic settings, it has been shown that self-effi...
