of factors and indicators increase (Chumney, 2012; Lowry & Gaskin, 2014). Although, PLS is known to be a robust method when above-mentioned conditions are satisfied, its main weakness is originally it does not provide the overall goodness of fit statistic for theory testing and confirmation. Therefore, a global measure of model fit is not possible to be given by PLS estimation (J. F. Hair Jr et al., 2010; Hair et al., 2011; Tenenhaus, Vinzi, Chatelin, & Lauro,

Discussion The present study presented four hypotheses. The first hypothesis proposed that high psychological well-being will be positively correlated with active procrastination. A multiple regression analysis proved this hypothesis (r=0.243, N=120, p<0.05). There was a small, but negative correlation between psychological wellbeing and passive procrastination. This shows that as active procrastination increases, psychological wellbeing decreases. This result was consistent with the findings of

Resistance to Change   I recently did a questionnaire from the Hebrew University of Jerusalem to assess my resistance to change and found my results to be about average.

Cancer risks will be considered “essentially negligible” where the estimated ILCR is 1-in-100,000 (≤ 1 x 10-5) (Health Canada 2004). If the ILCR is greater than 1 x 10-5, the risk assessment should either be refined and/or risk management measures should be taken. In this study, ILCR is greater than 1 x 10-5. ILCR values in different tissues such as mussels and liver 3 species of coral island of Persian Gulf were in the range of 0.032677 - 0.044428. Thus documenting high potential carcinogenic risk

General guidelines for screening for keratoconus: 1. Anterior and posterior elevation maps (Demirbas et al., 1998): In the anterior elevation map differences between the best fit sphere and the corneal contour of less than +12 μm are considered normal, between +12 μm and +15μm are suspicious, and more than +15 μm are typically indicative of keratoconus. Similar numbers about 5 μm higher apply to posterior elevation maps. 2. Anterior curvature map (Tomidokoro et al., 2000): The

Subliminal perception is defined as perceptual experiences which are triggered by sensory stimuli that are below the measured absolute threshold of conscious perception of a specific sensory organ.
