OBJECTIVE Controlled data on predictors of subjective sleep quality in patients with memory complaints are sparse. To improve the amount of comprehensive data on this topic, we assessed factors associated with subjective sleep quality in patients from our memory clinic and healthy individuals. METHODS Between February 2012 and August 2014 patients with mild cognitive impairment (MCI) and subj...

In this paper we merge individual census data, individual patenting data, and individual IQ data from Finnish Defence Force to look at the probability of becoming an innovator and at the returns to invention. On the former, we find that: (i) it is strongly correlated with parental income; (ii) this correlation is greatly decreased when we control for parental education and child IQ. Turning to ...

Security managers are always being offered new methods to test the security of their systems. Unfamiliarity with the terminology and types of testing can result in the manager not getting the services he or she is seeking. This article presents a taxonomy of terms in order to classify the different types of services available, and explain how each technique evaluates security controls in real-w...

Provides an overview of some of the findings of a recently completed study of school choice in 33 local schools which may be indicative of the effect of an increase in the marketisation of schools. Since it is unlikely that debate over parental choice can be settled by theoretical argument alone and it may also be too early to understand the full implications of the relevant recent government r...

We develop and estimate an equilibrium model of ability tracking. A school allocates students into tracks based on their ability and then chooses trackspecific inputs to test score production. Parents choose parental effort in response. We estimate the model using data from the ECLS-K. We use the estimated model to quantify the effects of allowing ability tracking, making proficiency standards ...

Recent legislation in the Netherlands requires that children should play a part in decision making regarding their own health care. So far, however, little attention has been given to the child’s participation in medical interviews. In order to get a grip on aspects of asymmetry and control in doctor–parent–child communication, the present study explores the turntaking patterns in this triad at...

Parental protection of eggs represents one of the most basic forms of parental care. Theory suggests that even such basic parental investment represents a trade-off between current offspring survival and future reproductive success. However, few studies have quantified the underlying costs and benefits of parental care for marked individuals across an entire lifetime. I marked and followed 370 ...
