Abstract: The paper employed a Cobb-Douglas stochastic production frontier function to estimate of technical efficiency (TE) with 770 observations of the cooperative farmer group (272, 243, and 255 in seasons 1, 2 and 3, respectively), and 900 observations of the non-cooperative farmer group (300, 324, and 276 in seasons 1, 2, and 3, respectively). The findings showed that TE of the cooperative farmer group was greater than that of the non-cooperative farmer group in season 1, while TE of cooperative group was lower than that of non-cooperative group in seasons 2, and 3. More so, the positive determinants of TE of the cooperative farmer group were the land area and plant density in three seasons, while the negative factors were the market access in season 1, the age and credit access in season 2. In the non-cooperative farmer group, the positive determinants were the plant density and land area in three seasons, the market access in season 2, whereas the negative elements were the wrapping bag i

Abstract: Brain oscillations are the prevalent features that may reflect the underlying physiological processes. Quranic sound stimulus which gained high attention in neuroimaging studies shows that the brain oscillations changed during perceiving the stimulus. Its rhythmic structure was assumed to interact with brainwaves rhythms producing neural entrainment. Hence this study was performed to investigate the oscillatory waveforms and spectral power changes to uncover the underlying neuronal mechanisms. Brain electrical data were measured by using the Electroencephalography followed by waveform analysis and Discriminant Analysis. Results showed that the waveforms amplitude were reduced, and a rhythmic and symmetrical pattern were found during listening to the Fatihah Chapter acoustic stimulus. Spectral power analysis showed that listening to this stimulus activate greater neural population associated with behavioral and cognition enhancement.
