Sayısız araştırma, öğretmen ve öğrencilere ait bilişsel üstbilişsel süreçlerin öğrencilerin akademik başarısında kritik bir rol oynadığını göstermektedir. Çalışma öncelikle öğretmenlerin kendi, kendi öğrencilerinin bilişine dair hedef, izleme kontrol süreçlerini içeren “eğitimde çok düzeyli düzenleme modeli” önermeyi amaçlamıştır. İkinci olarak, önerilen model çerçevesinde envanteri (EÜDE)”nin ...

Abstract We present a thermal history of the Kedougou Kenieba Inlier (eastern Senegal), western-central outcropping part West African Craton, based on 40Ar/39Ar analyses performed hornblende, biotite, and K-feldspar minerals from Paleoproterozoic plutonic rocks. age spectra obtained for hornblendes biotites range between 2055 ± 26 2028 ± 28 Ma, in very good consistency. They suggest that magmat...

Abstract Climate change has adverse impacts on Arctic natural ecosystems and threatens northern communities by disrupting subsistence practices, limiting accessibility, putting built infrastructure at risk. In this paper, we analyze spatial patterns of permafrost degradation associated risks to due loss bearing capacity thaw subsidence in regions the Arctic. Using a subset three Coupled Model I...

Conservation and natural resource management are frequently hampered by poor understanding of how species distributions have changed over time. Species Distribution Models (SDMs) correlate known occurrences with environmental variables to predict a species’ potential range. These models can then be projected unsurveyed areas or time periods overcome gaps in data on distribution. The eastern quo...

i) BB16 (1) provide no evidence that J15’s (2) cost, demand flexibility, or electrification assumptions are aggressive. Further, J15’s cost ranges are neither confidence intervals nor narrow (e.g., underground storage capital costs span over an order of magnitude), and, by far, most technologies proposed are commercial or extant for years. ii) BB16 (1) provide no evidence that J15’s (2) results...

Synoptic weather and larger scale circulation patterns are closely coupled have a major influence on regional extreme events. This study examines the role of circulations meteorology events for present future years over Asia with WRF model driven by HadGEM2 global boundary conditions that includes RCP4.5 scenarios based bicentennial transient simulation. The analysis was derived from 40 outputs...
