This article develops a model in which quit rates, and thus the income distribution, depend on employee perceptions of the accuracy of employer assessments of individual productivity because these latter assessments affect wages. When employees believe that these assessments are accurate, income inequality tends to be high. The model can account for the negative correlation across some countrie...
The present study examined the relationship between recent smoking cessation activities and sociodemographic characteristics, smoking intensity, and tobacco control policies among daily smokers in the United States. The study used the U.S. Current Population Survey 1998-1999 Tobacco Use Supplement, supplemented with information on state-level tobacco control policies. The sample was limited to ...
OBJECTIVE To evaluate the psychosocial and behavioural impact of the first ever national level comprehensive workplace smoke-free law, implemented in Ireland in March 2004. DESIGN Quasi-experimental prospective cohort survey: parallel cohort telephone surveys of national representative samples of adult smokers in Ireland (n = 769) and the UK (n = 416), surveyed before the law (December 2003 t...
The most common theory of smoking cessation postulates that readiness to quit begins with changes in attitudes that move the smoker toward behavioral change and eventual cessation.

The design problem for filters attenuating signals with frequencies outside the useful (pass) bands can be in many cases reduced to the problem of designing low pass or band-stop filters with sufficiently large bandwidths. It follows from the fact that some elements of complex electronic systems, as for example the radiating elements of antenna arrays, have the characteristics similar to those ...
