We present a study aimed at investigating how novel signs emerge and spread through a community of interacting individuals. Ten triads of participants played a game in which players created novel signs in order to communicate with each other while constantly rotating between the role of interlocutor and that of observer. The main result of the study was that, for a majority of the triads, commu...

*Thanks are due to Hans Rott and Maurice Pagnucco who have commented on the July draft of this essay and who subsequently sent me a draft of their ideas on contraction. I have sought here to explain how I came to change my mind and favor mild contractions (or severe withdrawals as Rott and Pagnucco call such contractions) and to indicate some of the relations between the approach of Rott and Pa...

This supplement is focused on the methods, results and recommendations from the research project ‘‘Methods of Assessing Response to Quality Improvement Strategies’’ (MARQuIS). MARQuIS was funded by the Scientific Support to Policies component of the European Union Sixth Framework Research Programme (Contract SP21-CT2004-513712), and it lasted from January 2004 to June 2008. MARQuIS was coordina...

Seven points chosen at random on a twisted cubic curve, like six points on a conic in the plane, give rise to a distinctive theorem; for as five points determine a conic, so the twisted cubic is determined by six points. In the case of the conic, this is the theorem of the Pascal hexagon, six points in a definite order leading to a definite line. Conic and line remaining fixed, the hexagon may ...

a r t i c l e i n f o Although the Dark Triad personality (i.e., Machiavellianism, narcissism, and psychopathy) has been researched widely, only few studies have investigated women's preferences for men who present high and low Dark Triad features. With an on-line two-alternative forced choice questionnaire we investigated the interaction between preferences of 1962 Finnish women for facial sti...

Abstract. The Brewer ozone spectrophotometer (the Brewer) was designed at Environment and Climate Change Canada (ECCC) in the 1970s to make accurate automated total column measurements. Since 1980s, instrument has become a World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) standard monitoring instrument. Now, more than 230 Brewers have been produced. To assure quality of meas...
