This paper provides a practical description of density estimation based on kernel methods. An important aim is to encourage practicing statisticians to apply these methods to data. As such, reference is made to implementations of these methods in R, S-PLUS and SAS.

This paper estimates the intergenerational transmission of trust by studying second generation immigrants in 29 European countries with ancestry in 87 nations. There is significant transmission of trust on the mother’s side. The transmission is stronger in Northern Europe. Ancestry from more developed countries suggests a stronger transmission of trust, but the heterogeneity in ancestry dissip...

conclusions our results demonstrated that the extract of ob could induce anxiolytic effect in rats after 1 week oral administration. the effect of ob was not induced through changes in motor activity. further investigations are necessary for pharmacological providing of ob and better understanding of its anxiolytic properties and neurobiological mechanisms. results the results showed that after...

putative activity of hydroalcoholic and aqueous infusion extracts of echium amoenum l. was investigated in mice using the rotarod model of motor coordination and the elevated plus maze model of anxiety. the extracts were administered intraperitonealy (i.p.) once, one hour before performing the tests. preliminary phytochemical study of the plant, with standard procedures, showed that it contains...

introduction: sildenafil, a phosphodiesterase-5 (pde5) inhibitor, may have various effects on the central nervous system via the nitric oxide (no)-cyclic guanosine monophosphate (cgmp) pathway. preclinical studies have shown the controversial effect of sildenafil on anxiety-like behavior in animals. this study was undertaken to investigate the acute effect of sildenafil on anxiety-like behavior...

Most office buildings in the warm-humid sub-Saharan countries experience high cooling load because of the predominant use of sandcrete blocks which are of low thermal mass in construction and extensive use of glazing. Relatively, low night-time temperatures are not harnessed in cooling buildings because office openings remain closed after work hours. An optimization was performed through a sens...

We evaluated four techniques for controlling focus+context screens. We compared an egocentric versus exocentric View mixed with whether the display on the focus screen moves in the same (paper mapping) versus opposite (scroll mapping) direction as input force. Our results show that (i) View had little effect, (ii) users almost always allocated attention to the context screen when controlling th...
