This paper, the second in a duology reporting on an action research project about public health services in Venezuela, presents a narrative of an intervention process launched on the basis of the conceptual framework presented in the first paper of the duology. Thereafter, a deeper reflection on such process, its meaning and its historical possibilities is presented. In this way a cycle of research-action-research is completed. 相似文献

This article is a summary of an interpretive-systemic study of the University of Los Andes in Venezuela. Following the methodological guidelines of interpretive systemology, three interpretive contextual systems were designed in order to comprehend the sense of the university. These three interpretive contexts were derived from possible different interpretations of the University Law (Statutes). Results obtained from the thematic interpretation of university activities and decision taking reveal an institution removed from any of the missions depicted in the interpretive contexts. A fourth interpretive context was designed to provide an interpretation of the regulative role the institution plays in order to maintain a particular social order and power structure. This fourth interpretive context shows greater interpretive power with regard to actual university activities than the other three. 相似文献

This is the second article in a trilogy devoted to inquiring about the historical meaning of the intimate link between a systems approach and world issues, so appropriate for Churchman's initial work on systems. After examining the logical relationship between modern systems thinking and world issues in the first article, in this second article the historical conditions for the formation of modern systems thinking are explored. It is shown how the intimate relationship between the will to systems and the notion of humanity gives full meaning, within the modern constellation, to Churchman's plea for a systems approach to world problems. However, in the light of this historical–ontological inquiry, systems thinking appears as both a propellant for the formation of the new constellation of modernity and a propellant for its destruction. 相似文献

Processing of wild cereal grains in the Upper Palaeolithic revealed by starch grain analysis 总被引:1,自引:0,他引:1
Barley (Hordeum vulgare L.) and wheat (Triticum monococcum L. and Triticum turgidum L.) were among the principal 'founder crops' of southwest Asian agriculture. Two issues that were central to the cultural transition from foraging to food production are poorly understood. They are the dates at which human groups began to routinely exploit wild varieties of wheat and barley, and when foragers first utilized technologies to pound and grind the hard, fibrous seeds of these and other plants to turn them into easily digestible foodstuffs. Here we report the earliest direct evidence for human processing of grass seeds, including barley and possibly wheat, in the form of starch grains recovered from a ground stone artefact from the Upper Palaeolithic site of Ohalo II in Israel. Associated evidence for an oven-like hearth was also found at this site, suggesting that dough made from grain flour was baked. Our data indicate that routine processing of a selected group of wild cereals, combined with effective methods of cooking ground seeds, were practiced at least 12,000 years before their domestication in southwest Asia. 相似文献
