Abstract

Despite the importance of Perisphinctidae ammonite family as a tool (or biogeographic correlation and biostratigraphy during the Oxfordian, these studies are frequently hampered by the intraspecific morphological and geographical variability, and the traditionally used tipologist species concept. A modern systematics, based on a biological species concept (biospecies) taking into account all types of intraspecific variability is likely to provide a more reliable phyllogenetic-biostratigraphic frame, leading as well to a better comprehension of the biogeographic dynamics of the group. The studied recorded successions in the Middle Oxfordian of Rida (NE Iberian Chain, Spain) known by their abundance and by the completeness of the ammonite record, supply a good evidence for the analysis of intraspecific variability and biospecies concept

Abstract

Introduction: We assess the attitudes of Spanish doctors towards immigrant patients., Design: cross-sectional descriptive study carried out in January-June 2003., Sample and Setting: Family doctors and third-year residents of 15 health care centers in Zaragoza, Spain., Instrument: specifically designed interview answered in anonymously and on a voluntary basis., Results: A total of 62.3 % of the sample responded. Nearly 75 % of the doctors had received training on immigration, mainly from a theoretical point of view. Almost 25 % of immigrant consultations are not related to health matters. Doctors think that immigrant patients somatize more than Spanish ones but they do not suffer from more psychiatric illness. They also think immigrants show less treatment compliance and are more demanding. They disagree about possible racial biases in diagnosis or treatment of these patients. Spanish doctors consider that the different ethnic groups present similar management difficulties. The group with the most negative stereotype was the patients from Muslim North African countries., Discussion: These findings are discussed from a psychological and anthropological perspective.
