BACKGROUND It has been reported that high levels of sex hormones improve the efficiency in tasks which are usually better performed by females. In contrast, in tasks which are usually better performed by males, the best efficiency corresponds to low levels of sex hormones. The aim of this study was to examine changes of efficiency in tasks of verbal fluency and mental rotations, as well as chan...

The present experiment examined pilot response to the rapid cycling of automation. The experiment was conducted using a multi-task simulation environment consisting of tracking, fuel management, and system monitoring sub-tasks. Monitoring and fuel management sub-tasks were performed manually in all conditions. The tracking sub-task cycled between manual and automated control at fixed intervals ...

in this paper, we introduce fractional order of a planar fractional prey-predator system with a nonmonotonic functional response and anti-predator behaviour such that the adult preys can attack vulnerable predators. we analyze the existence and stability of all possibleequilibria. numerical simulations reveal that anti-predator behaviour notonly makes the coexistence of the prey and predator po...

conclusions the results of this study led to the identification of many of the errors and conditions that affect the performance of controllers, providing the ability to define safety and ergonomic interventions to reduce the risk of human error. therefore, the results of this study can be a basis for planning atm to prioritize prevention programs and safety enhancement results the analysis of ...

the necessity and importance of teaching pragmatics has come to light by many researchers (e.g. rose & kasper, 2001). due to the consensus over the need to teach pragmatic competence, the main issue now centers on the question of how we should teach this competence in the most effective way. consistent with this line of research, the present study aimed to investigate the effectiveness of d...

The ability to write effectively is becoming progressively important and instruction in writing is assuming an increasing role in second and foreign language education. Students’ writing abilities have been tested through various writing tasks. Independent tasks of writing or writing-only tasks have been utilized to test students’ writing ability; however, they have been criticized for their la...

Nowadays, in a competitive and dynamic environment of businesses, organizations need to moni-tor, analyze and improve business processes with the use of Business Process Management Systems(BPMSs). Management, prediction and time control of events in BPMS is one of the major chal-lenges of this area of research that has attracted lots of researchers. In this paper, we present a...
