The study aimed to reveal the strategic vigilance’s impact in Saudi universities through its dimensions: (competitive vigilance, technological vigilance). descriptive analytical approach was used this research, and sample included (62) faculty members three (Hail University, Umm Al-Qura Taibah University). necessary statistics were conducted, addition testing validity of hypotheses. It conclude...

Vigilance by California ground squirrels (Spermophilus beecheyi) following two kinds of naturally occurring "alarm" calls was examined. Chatters were usually singly emitted calls while repetitive calls were initiated by one or more chatters and continued with a variable, but long, series of "chats." During noncalling periods adults tended to be more vigilant than were pups (young of the year); ...

I examined the vigilance behavior of adult males and females in two groups of ring-tailed lemurs (Lemur catta) during the birth and lactation season at the Beza-Mahafaly Reserve, southwestern Madagascar. I found no sex difference with respect to the rates of overall vigilance, rates of vigilance toward a potential predator or unfamiliar sound, or rates of vigilance toward conspecifics from othe...

Variational autoencoders (VAEs), that are built upon deep neural networks have emerged as popular generative models in computer vision. Most of the work towards improving variational autoencoders has focused mainly on making the approximations to the posterior flexible and accurate, leading to tremendous progress. However, there have been limited efforts to replace pixel-wise reconstruction, wh...

Human error has been implicated as a causative factor in 85% of drivers’ and operators’ crashes, and lack of vigilance has been identified as the single most important factor in incidents involving human error. Driver vigilance could decline with sleepiness, fatigue or monotony. In Queensland, inattention and fatigue respectively contribute to 27% and 5% of reported crashes. Vigilance decline i...

Functional near infrared spectroscopy (fNIRS) measures of cerebral oxygenation levels were collected from participants performing difficult and easy versions of a 12 min vigilance task and for controls who merely watched the displays without a work imperative. For the active participants, the fNIRS measurements in both vigilance tasks showed higher levels of cerebral activity than was present i...

To investigate the effects of monotonous daytime driving on vigilance state and particularly the ability to judge this state, a real road driving study was conducted. To objectively assess vigilance state, performance (auditory reaction time) and physiological measures (EEG: alpha spindle rate, P3 amplitude; ECG: heart rate) were recorded continuously. Drivers judged sleepiness, attention to th...

Previous research has shown that under certain rather explicit conditions it is possible to facilitate performance on a vigilance task by performing another vigilance task simultaneously. The question arises as to whether or not performance on at; auditory vigilance task is facilitated by simultaneously performing a continuous tracking task. It was concluded from the study reported here that in...
