task-based language teaching in iran: a mixed study through constructing and validating a new questionnaire based on theoretical, sociocultural, and educational frameworks
جنبه های گوناگونی از زندگی در ایران را از جمله سبک زندگی، علم و امکانات فنی و تکنولوژیکی می توان کم یا بیش وارداتی در نظر گرفت. زبان انگلیسی و روش تدریس آن نیز از این قاعده مثتسنی نیست. با این حال گاهی سوال پیش می آید که آیا یک روش خاص با زیر ساخت های نظری، فرهنگی اجتماعی و آموزشی جامعه ایرانی سازگاری دارد یا خیر. این تحقیق بر اساس روش های ترکیبی انجام شده است.پرسش نامه ای نیز برای زبان آموزان ...
Epiphyte metapopulation dynamics are explained by species traits, connectivity, and patch dynamics.
The colonization-extinction dynamics of many species are affected by the dynamics of their patches. For increasing our understanding of the metapopulation dynamics of sessile species confined to dynamic patches, we fitted a Bayesian incidence function model extended for dynamic landscapes to snapshot data on five epiphytic lichens among 2083 mapped oaks (dynamic patches). We estimate the age at...
متن کاملEffects of patch connectivity and arrangement on animal metapopulation dynamics: a simulation study
Wu, J., Vankat, J.L. and Barlas, Y., 1993. Effects of patch connectivity and arrangement on animal mctapopulation dynamics: a simulation study. Ecol. Modelling, 65: 221-254. We constructed a simulation model of metapopulation dynamics consisting of two or three habitat patches using STELLA. our simulations show that, given the assumptions of the deterministic model, the metapopulation is doomed...
متن کاملLinking extinction-colonization dynamics to genetic structure in a salamander metapopulation.
Theory predicts that founder effects have a primary role in determining metapopulation genetic structure. However, ecological factors that affect extinction-colonization dynamics may also create spatial variation in the strength of genetic drift and migration. We tested the hypothesis that ecological factors underlying extinction-colonization dynamics influenced the genetic structure of a tiger...
متن کاملExtinction threshold in metapopulation models
The term extinction threshold refers to a critical value of some attribute, such as the amount of habitat in the landscape, below which a population, a metapopulation, or a species does not persist. In this paper we discuss the existence and behavior of extinction thresholds in the context of metapopulation models. We review and extend recent developments in the theory and application of patch ...
