BACKGROUND Sedation is frequently used during colonoscopy to control patient discomfort and pain. Propofol is associated with a deeper level of sedation than is a combination of a narcotic and sedative hypnotic and, therefore, may be associated with an increase in force applied to the colonoscope to advance and withdraw the instrument. OBJECTIVE To compare force application to the colonoscope...

this paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. axial bearing analysis is done numerically using nonlinear finite element code ls-dyna. in this analysis, changes of two main parameters including measure of energy absorption o...

This study derives kinematic admissible bending moment – axial force (M-P) interaction relations for mild steel by considering elastic-plastic idealizations. The interaction relations can predict strains, which is not possible in a rigid perfectly plastic idealization. The relations are obtained for all possible cases pertaining to the locations of neutral axis. One commercial rolled steel T-se...

A field study of 84 registered nurses and their supervisors revealed that leaders' perceptions of leader-follower attitudinal similarity and follower extraversion were positively related to the quality of leader-follower exchanges. Neither followers' locus of control nor growth need strength was found to be significantly correlated with the quality of the exchange between leaders and followers.

To address present and future leadership needs, a model of authentic leader and follower development is proposed and examined with respect to its relationship to veritable, sustainable follower performance. The developmental processes of leader and follower self-awareness and self-regulation are emphasized. The influence of the leader’s and followers’ personal histories and trigger events are c...

Previous studies have established the relationship between ethical leadership and a variety of positive follower outcomes. They have investigated a number of psychological mechanisms that mediate these relationships. In terms of mediators, follower organizational identification has been found to mediate the relationship between ethical leadership and follower job performance. In this research, ...
