the relationship between academic self-concept and academic achievement in english and general subjects of the students of high school
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
Within-breath variations of forced oscillation resistance in healthy subjects.
Respiratory resistance (Rrs) was measured by the forced oscillation technique at 10, 20 and 30 Hz in 54 healthy subjects. The sinusoidal pressure oscillations were applied around the head, rather than at the mouth, so as to minimize transmural pressure across extrathoracic airway walls and the corresponding artefact (Peslin et al., J Appl Physiol, 1985, 59, 1790-1795). The flow (V') and volume ...
متن کاملA Comparison of Within-Subjects and Between-Subjects Designs in Studies with Discrete-Time Survival Outcomes
Crossover designs are well-known to have major advantages when comparing the effects of various non-curative treatments. We compare efficiencies of several crossover designs along with the Balaam’s design with that of a parallel group design pertaining to longitudinal studies where event time can only be measured in discrete time intervals. With equally sized sequences, the parallel group desig...
متن کاملPrestimulus oscillations predict visual perception performance between and within subjects
In the present study, the electrophysiological correlates of perceiving shortly presented visual stimuli are examined. In particular, we investigated the differences in the prestimulus EEG between subjects who were able to discriminate between four shortly presented stimuli (Perceivers) and subjects who were not (Non-Perceivers). Additionally, we investigated the differences between the subject...
متن کاملExtracerebral layers ( ECL ) thickness variation within a subject between subjects
Objectives: To characterize the variations in extracerebral layer (ECL) thickness that exists within a subject. Secondly, to compare these ECL thickness variations across a group of subjects at two standardized location (at the level of the anterior commissure (AC) & 20mm above the AC (AC+20mm)). Finally, the influence of these ECL variations on propagation of light using the Monte Carlo simula...
