a tripartite model of efl teachers attributions, burnout, and self-regulation: towards the prospects of effective teaching
همطالعه حاضر به ارائه مدلی برای آموزش موثر زبان انگلیسی می پردازد. مدل حاضر از سه عامل تاثیر گذار در کارایی تدریس معلمان زبان انگلیسی بهره می برد. این سه عامل شامل سبکهای اسنادی، خود تنطیمی و فرسودگی شغلی معلمان ایرانی زبان انگلیسی می باشد. رساله مورد نظر درچهار فاز طراحی شده است: فاز اول شامل طراحی و رواسازی پرسشنامه سبکهای اسنادی معلمان زبان انگلیسی و فاز دوم شامل استفاده از این پرسشنا...
Effective Mass of Atom and Excitation Spectrum in Liquid Helium - 4 at T = 0
A self-consistent approach is applied for the calculations within the two-time temperature Green functions formalism in the random phase approximation. The effective mass of 4He atom is computed as m∗ = 1.58m. The excitation spectrum is found to be in a satisfactory agreement with the experiment. The sound velocity is calculated as 230 m/s. The temperature of the Bose-condensation with the effe...
متن کاملMolecular Hydrogen Excitation around Active Galactic Nuclei
We report R ∼ 3000 Very Large Telescope ISAAC K-band spectroscopy of the nuclei (i.e. central 100–300pc) of nine galaxies hosting an active galactic nucleus. For five of these we also present spectra of the circumnuclear region out to 1 kpc. We have measured a number of molecular hydrogen lines in the ν = 1−0, 2−1, and 3−2 vibrational transitions, as well as the Brγ and He i recombination lines...
متن کاملEffective Field Theories for Hadrons and Nuclei
Hadron structure and nuclear structure are discussed from the common ground of effective chiral Lagrangians modeling QCD at low energy. The topics treated are the chiral bag model in large Nc QCD, its connection to heavy-baryon chiral perturbation theory (HBχPT), the role of nonabelian Berry gauge connections for baryon excitations and the application of HBχPT to the thermal n+p → d+γ process a...
متن کاملEffective theory for deformed nuclei
Here, I ≥ I0 denotes the angular momentum, A is a constant determined by fit to data, and I0 is the spin of the band head under consideration. Rotational states are the lowestlying excitations in nuclei far away from closed shells. Our understanding of nuclear rotations is based on the groundbreaking work by Bohr and Mottelson [1], its extension within the general collective model [2], and the ...
