Marked sleepiness occurs during typical night shift work hours and this reduced alertness is associated with marked performance deficits. The effect of caffeine (versus placebo) upon sleepiness at night was studied using objective measures of physiological sleep tendency and ability to sustain wakefulness. Both measures show caffeine to reduce sleepiness at a single dose roughly the equivalent of two to four cups of coffee. Despite impressive objective differences in alertness with caffeine, subjects did not consistently differentiate between drug conditions on subjective alertness assessments. The use of CNS stimulants to promote alertness during night shift hours should be considered, particularly for occupations for which alertness is critical.
PurposeThe purpose of this paper is to provide an explanation of the DiSC personality model along with a real‐world example of its effectiveness.Design/methodology/approachThe DiSC personality model explores people's communication priorities and how those priorities influence behavior. Kudu Industries is one company that has successfully implemented DiSC throughout the company, and this paper serves as an example of the model's use within an organization.FindingsEvery individual within an organization has unique priorities and work styles, therefore they prefer to be addressed in unique ways. When a company dedicates the necessary resources to learning about the various work styles of its employees, productivity increases.Originality/valueCompanies that are not paying serious attention to employee communication behaviors should take a second look. This paper shows that organizations that take behavioral training seriously stand to benefit greatly.
