Scientific-Methodological Bases of Assessment of Population Health Risk in Complex Ecological-Hygienic Studies of Territories
Despite big quantity of studies of various pollutants’ influence on population health, many questions of methodical and methodological character remain disputable and unresolved till now. In practice, it is difficult to determine real contribution of a concrete source to common pollution, to estimate probability of development and a degree of expressiveness of adverse consequences for human health. In this connection on the basis of the risk conc…
O2-1.4 Significant increase followed by dramatic decrease of infant leukaemia rates in Belarus
The question of whether child acute leukaemia (ChAL) incidence in most contaminated countries has changed as a result of Chernobyl remains of great interest. We present results of age-cohort-period analyses of IR trends of ChAL from 1979 to 2006 in Republic of Belarus. Number of cases was tabulated by age at diagnosis and period of observation (preaccident, 1979–1985) and postaccident: 1986–1992, 1993–1999, 2000–2006. During first 7 years after t…
Problems of Ethnosemiotics
In researching exchange as an "integral social fact," Mauss and his school, as well as Hocart and Needham, came to the conclusion that in ancient times there existed a nondifferentiated society, in which the exchange of social and material values (including "the exchange of partners"—i.e., spouses—according to Lévi-Strauss), ritualized mutual relations, and activity equivalent to the arts in contemporary society are regarded as virtually indistin…
Language Systems and Principles of Reconstruction in Linguistics
Two levels can be distinguished in the structure of a language as a system of signs: the level of expression and the level of contents. Every sign of a language will thus be characterized by the unity of these two aspects. We can distinguish therein the signifying (.signans) and the signified (signatum), which correspond to the two levels of the language. Relations between the signifying and the signified in linguistic signs are determined by the…
Sprachtypologie und die Rekonstruktion der gemeinindogermanischen Verschlüsse
Typological considerations both of phonemic structure and of phonemic change call for a restatement of the system of primitive Indo-European stops. The two series so far taken to be voiced and voiceless are reinterpreted as glottalized and voiceless aspirate, respectively. The languages believed to have undergone major consonant shifts (Germanic, Armenian, Hittite) turn out to be very conservative as far as their consonant systems are concerned.
