Single measures of deprivation.
STUDY OBJECTIVE A number of measures have been developed which attempt to combine a range of variables into a single, more easily understood dimension of "deprivation". These extend from fairly simple additive measures through to those based on more sophisticated statistical techniques. All attempts to simplify a number of variables into a single, summary measure have limitations. This paper co...
متن کاملDynamic Measures of Individual Deprivation
We introduce and axiomatize a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the part of deprivation generated by an agent’s observation that others in its reference group move on to a higher level of income than itself. The parameter reflects the relative ...
متن کاملEEG measures index neural and cognitive recovery from sleep deprivation.
Sleep deprivation impairs many cognitive abilities, but these impairments can be reversed after a certain quantity and quality of sleep. The ability to inhibit responding is particularly susceptible to disruption after prolonged wakefulness. How recovery sleep (RS) alters brain activity, leading to improved performance on a variety of cognitive tasks, remains unclear. This issue was examined in...
متن کاملSmoking behaviour can be predicted by neighbourhood deprivation measures.
STUDY OBJECTIVE To assess whether small area measures of socioeconomic deprivation predict variation in individual smoking behaviour. To examine the adequacy of an individual level statistical model for the analysis of data on groups of individuals who live in the same geographical area. DESIGN Individual level and two level logistic regression analysis of data on individual smoking from a re...
متن کاملClassifying vulnerability to sleep deprivation using baseline measures of psychomotor vigilance.
OBJECTIVES To identify measures derived from baseline psychomotor vigilance task (PVT) performance that can reliably predict vulnerability to sleep deprivation. DESIGN Subjects underwent total sleep deprivation and completed a 10-min PVT every 1-2 h in a controlled laboratory setting. Participants were categorized as vulnerable or resistant to sleep deprivation, based on a median split of lap...
