It is widely held, to the point of being the received interpretation, that Frank Ramsey was the first to defend the so-called Redundancy Theory of Truth in his landmark article ‘Facts and Propositions’ (hereafter ‘FP’) of 1927. For instance, A.J. Ayer cited this article in the context of arguing that saying that p is true is simply a way of asserting p and that truth is not a real quality or re...

Erratum After publication of the original article [1], it came to the authors’ attention that the Acknowledgements section was not completed correctly. Instead of “Not applicable”, the Acknowledgements of the article should have been as follows. Acknowledgements We would like to thank all of the following contributors for their invaluable expertise: Neill Calvert for performing and writing-up t...

on thyroxine-binding proteins (UTBP), T4 bound to thyroxine-binding proteins (PBI or TBPT4) andfree thyroxine (FT4). thyroid status. This is shown in diagrammatic fashion in fig 1 which illustrates the changes that occur in thyrotoxicosis and hypothyroidism and in those situations where there are alterations in thyroxine-binding protein capacity, such as the increase in thyroxine-binding globul...

Internet pricing is receiving increased attention in industry and academia. In this paper, we report the results of comparing two Internet pricing models. Using simulation techniques, we evaluate the technical and economic efficiencies of the Smart Market model proposed by MacKie-Mason & Varian (1993) and compare it with Dynamic Capacity Contracting, a pricing scheme that we have developed. Dyn...

Bacterial dissolution and degradation of particles is an important process in the cycling of organic matter in the ocean. Because particles are the primary vehicles for vertical export of organic material from the oceans’ productive surface layer to the deep sea, bacteria associated with marine particles contribute to the export of organic matter and to the regulation of its magnitude and compo...

Recent advances in understanding prejudice and intergroup behavior have made clear that emotions help explain people's reactions to social groups and their members. Intergroup emotions theory (D. M. Mackie, T. Devos, & E. R. Smith, 2000; E. R. Smith, 1993) holds that intergroup emotions are experienced by individuals when they identify with a social group, making the group part of the psycholog...

Previous research [Smith, E. R., Seger, C. R., & Mackie, D. M. (2007). Can emotions be truly group-level? Evidence regarding four conceptual criteria. Journal of Personality and Social Psychology, 93, 431–446] has demonstrated that when people are explicitly asked about the emotions they experience as members of a particular group, their reported emotions converge toward a profile typical for t...

We reviewed the scientific literature addressing physiological constraints of zebra mussel and found seven studies that measured the effects of water calcium concentrations (mg/l, hereafter Ca) on zebra mussel development and growth (Jones and Ricciardi 2005, Allen and Ramcharan 2001, Hincks and Mackie 1997, Mellina and Rasmussen 1994, Ramcharan et al 1992, Strayer 1991, Sprung 1987). A 95% con...

Para contribuir com a essa análise, o artigo apresenta uma introdução às temáticas filosofia medicina epidemiologia, especialmente exame papel causalidade, conceito fundamental para compr...

Morphogenesis of embryonic organs is regulated by epithelial-mesenchymal interactions associating with changes in the extracellular matrix (ECM). The response of the cells to the changes in the ECM must involve integral cell surface molecules that recognize their matrix ligand and initiate transmission of signal intracellularly. We have studied the expression of the cell surface proteoglycan, s...
