Workaholism, sleep disorders, and potential e-learning impacts among Menoufia university staff during COVID-19 pandemic.

Background: Workaholism is described as a constant, internal drive to work and behavioral addiction to work. Studies have shown the negative associations between workaholism, job performance, and health results as disrupted sleep. The purpose of this research was to compare the prevalence of workaholics among the academic staff of practical and theoretical Faculties in Egyptian universities using the Dutch Workaholism Scale (DUWAS) and to determine associated sleep problems.

The role of convexity in perception of symmetry and in visual short-term memory.

Visual perception of shape is affected by coding of local convexities and concavities. For instance, a recent study reported that deviations from symmetry carried by convexities were easier to detect than deviations carried by concavities. We removed some confounds and extended this work from a detection of reflection of a contour (i.

The shape of a hole and that of the surface-with-hole cannot be analyzed separately.

Figure-ground organization has a central role in visual perception, since it creates the regions to which properties, such as shape descriptions, are then assigned. However, there is disagreement on how much shape analysis is independent of figure-ground. The reversal of figure-ground of a single closed region is the purest form of figure-ground organization, and the two resulting percepts are that of an object and that of a hole.
