Colonialism and Underdevelopment: Critical Remarks on the Theory of Dependency

As historians, living in the contemporary world, we ask and are asked about the causes of underdevelopment. And, as most of the former colonies belong today to the underdeveloped countries of the Third World, we are confronted with the question as to what importance the colonial era plays in the history of these countries. There is a consensus that the history of colonialism can only be meaningful approached in the broader spectrum of underdevelopment and the specific problems of the Third World. There is no satisfaction in retreatingto the ostensibly objective approach of the historian and wanting tolimit ourselves in showing how colonialism came into being, what administrative structures arose, what economic policies were followed and finally how the colonized revolted and the process of decolonization got under way. Society will simply not allow us to do so. Equally, if not more important, is the question regarding the impact of colonialism on the colonized societies and how far it may be held responsible for the existing structures of underdevelopmen

Micromechanical Properties of Injection-Molded Starch–Wood Particle Composites

The micromechanical properties of injection molded starch–wood particle composites were investigated as a function of particle content and humidity conditions. The composite materials were characterized by scanning electron microscopy and X-ray diffraction methods. The microhardness of the composites was shown to increase notably with the concentration of the wood particles. In addition,creep behavior under the indenter and temperature dependence were evaluated in terms of the independent contribution of the starch matrix and the wood microparticles to the hardness value. The influence of drying time on the density and weight uptake of the injection-molded composites was highlighted. The results revealed the role of the mechanism of water evaporation, showing that the dependence of water uptake and temperature was greater for the starch–wood composites than for the pure starch sample. Experiments performed during the drying process at 70°C indicated that the wood in the starch composites did not prevent water loss from the samples.Peer reviewe
