هدف: هدف از انجام این پژوهش مقایسه اثربخشی طرحوارهدرمانی و واقعیتدرمانی بر انعطافپذیری روانشناختی خودتنظیمی هیجانی مربیان پیشدبستانی شهرستان شهرکرد بود. روش: جامعه آماری کلیة شهرکردبودند که بین آنها تعداد 45 نفر به صورت نمونهگیری در دسترس انتخاب گمارش تصادفی 2 گروه آزمایش و1 کنترل (هر کدام 15 نفر) گمارده شدند. ابزار اندازهگیری شامل پرسشنامههای (بوند همکاران، 2011) هیجانی(مارس، 1983) بو...
Abstract The overall aim of this study is to enable the traceable International System Units (SI) determination column-integrated aerosol optical depth (AOD) retrieved from passive remote sensing atmosphere using SI-traceable direct solar spectral irradiance measurements. A precision filter radiometer that measures for retrieval AOD has been characterized and calibrated at state-of-the-art cali...
The objective of this report is to document progress since IWTC-V in this thematic area from experimental, observational, empirical, theoretical, and numerical perspectives. The report begins by describing progress in upper-ocean processes that include the oceanic mixed layer (OML) and the thermocline. This section is followed by a discussion of the air-sea interface that includes surface winds...
Ozone concentrations have been decreasing globally for the last 20 years in part due to increasing chlorine concentrations in the stratosphere (WMO 1999). The most dramatic example of these reductions has been identified in the high latitude southern hemisphere, where ozone levels are nearly entirely depleted in the lower stratosphere during September and October each year. This phenomenon, whi...
Considerable errors may be introduced in storm intensity estimations and their subsequent applications if raw surface wind speed records are not corrected to properly account for exposure effects. This study investigates the calculation of correction factors ( ECFs $$ \mathrm{ECFs} ) by different theoretical code-based models. Estimation roughness length z 0 {z}_0 based on suitable gustiness mo...
