In 1952, Alan Turing published a seminal paper “The chemical basis of morphogenesis” [Turing, 1952]. His intriguing ideas influenced the thinking of theoretical biologists and scientists from many fields, successfully developed on the theoretical backgrounds [Murray, 1982; Ni & Tang, 2005; Satnoianu et al., 2000; Segel & Jackson, 1972; Szili & Tóth, 1997]. The Turing mechanism has been successf...

The solvency standards implicit in bank capital levels, as reported eg in Jackson et al (2002), are much higher than those required for top ratings, if standard single period economic capital models are taken seriously. We explain this excess capital puzzle by forward looking rating targeting behaviour by banks, which aims at maintaining rating above a minimum target in future periods. We calib...

concentrations of several solutes – nitrate, arsenic, sulfate, boron, chloride, and bromide – along with total dissolved solids (tds) in ten counties bordering the brazos river in east-central texas were compiled, mapped, and analyzed relative to regional land use and geology. agriculture and oil/gas production are major activities and potential sources of groundwater contamination in the study...

As mulheres integrantes da sociedade nórdica do século X foram, algumas vezes, retratadas como guerreiras, além poderem assumir o papel marido quando este não estivesse disponível. Diante disso, buscou-se analisar uma possível semelhança entre a mulher e personagem Éowyn romance de J.R.R. Tolkien, O Senhor dos Anéis, publicado 1954-1955. Em seguida, pretendeu-se maneira foi ressignificada na ad...

We concentrate on the problem of the provision of one pure public good whenever agents that form the society have either single-plateaued preferences or single-peaked preferences over the set of alternatives. We are interested in comparing the relationships between di¤erent nonmanipulability notions under these two domains. On the single-peaked domain, under strategy-proofness, non-bossiness is...
