Scientific relations between Spain and central-Eastern European countries for the period 1982–1992
This paper analyzes the scientific relationships between Spain and the Eastern European countries (EEc), including the former USSR, from 1982 to 1992. The study considers the number of co-authored papers as well as the number of stays which reflect to the exchange of scientists among them. The total number of co-authored papers of Spanish scientists with their colleagues of those countries is 664 as recorded in theScience Citation Index. During the last three years, a significative increase in the number of co-signed papers has been observed. From the sample considered, the percentage of bilateral and multilateral co-authored papers is 43.8 and 56.2 respectively. In absolute figures, USSR and Poland are the countries with highest number of collaborative papers with Spain. However, in relation to their scientific output, Poland and Hungary show a higher percentage of co-authored papers than the rest of EEc. On the other hand, previous data, provided by the Spanish Secretary of State for Research and Universities (SEUI), related to the flow of scientists on sabbatical year to and from Spain,1 showed that from 1984 to 1994, a total of 213 researches come from the EEc to Spain, while the number of Spanish scientists going to those countries was extremely scarce.
International scientific cooperation: The continentalization of science
By transforming science into a vast single market for the exchange of research products, the globalization of scientific activity effects the mechanisms by which countries enter into mutual relations. It is no longer sufficient to conduct research jointly; research must also, and perhaps above all, be conducted within the strategic space of the network. In practice, the network takes the form of a cluster of nations and emerges in response to various determining factors or constraints. This does not, however, result in arbitrary criteria of association with the network: the distance from one country or group of countries able to play a regional or continental “governance” role, cultural or linguistic affinities, geographic proximity, the recognition of common interests, the existence of political agreements on cooperation are all grounds for linkage or association. In short, the geography of exchanges is changing before our eyes. This study describes as “world-science” marked by the collectivization of the centre, “centrality” being defined not by a national monopoly, but by the “hard core” of a transnational network, stratified on a continental or subcontinental basis.
Pig Vocalizations Under Selected Husbandry Practices
Acoustical characteristics of vocalizations of sows, piglets, and nursery pigs under selected husbandry practices were analyzed with a digital signal processing system. The duration (D) and major energy-resonance frequency (P) for each call were determined as follows: a) processing of piglets (D = 0.81 s and f* = 3 700 Hz); b) food anticipation of breeding-gest ation sows (2.50 s and 3 000 Hz); c) isolation of piglet (0.34 s and 500, 3 500 Hz); d) startling of nursery pigs (0.29 s and 900 Hz); e) sows in heat (3.07 s and 1 375 Hz); f) farrowing (0.10 s and 3 000 Hz); g) sow nursing (0.15 s and 1 000 Hz); and h) mate greeting of sow (0.13 s and 1 000 Hz). Calls a) to d) are responses to human generated stressors, and calls e) through h) responses to social and physiological states of the pigs. Thus, vocalizations can be segmented for different pig production situations.
