Why do foreign aid budgets vary across countries and over time? Existing research indicates that the same set of factors shapes commitments toward both domestic and international redistribution. While scholars have acknowledged international normative influences on aid allocations, research on levels of donor generosity has not examined how international trade influences aid budgets. This paper examines whether imports from developing countries have a ‘displacement effect’ on aid commitments. Employing a panel of nineteen OECD donor countries, we analyze aid budgets from 1980 to 2000. We find that increased imports from developing countries to donor countries are associated with aid reductions. These results persist after controlling for international and domestic variables identified in previous research, and under other estimation techniques and model specifications.  相似文献

The model described in the present paper has been worked out to approximate a concrete problem of national economic planning. The problem presented itself in the daily practice of the National Planning Board of the Hungarian People's Republic in the course of a planning project carried out with the aim of laying the foundation of the national economy's long-term development.  相似文献

The temperature-dependent development of the forensically important flesh fly Liopygia (Thomsonea) argyrostoma (Robineau-Desvoidy) (=Sarcophaga argyrostoma) was studied at six constant temperature regimes in the laboratory. Total developmental time of L. argyrostoma from larviposition to adult emergence was 54.9+/-1.45, 31.3+/-1.1, 22.2+/-0.67, 16.3+/-0.54, and 14.9+/-0.4 days (+/-S.D.) when reared at 15, 20, 25, 30, and 35 degrees C, respectively. At 8 degrees C, larval development was not completed. From linear regression of development rates of five of the six studied constant temperature regimes, it was determined that the minimum development threshold (tL) for total immature development is 7.4 degrees C, and the overall thermal constant (K) for L. argyrostoma is 396.4+/-19.18 (mean +/- S.D.) day-degrees (DD) above the threshold.  相似文献

Postmortem investigation is increasingly supported by Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). This led to the idea to implement a noninvasive or minimally invasive autopsy technique. Therefore, a minimally invasive angiography technique becomes necessary, in order to support the vascular cross section diagnostic. Preliminary experiments investigating different contrast agents for CT and MRI and their postmortem applicability have been performed using an ex-vivo porcine coronary model. MSCT and MRI angiography was performed in the porcine model. Three human corpses were investigated using minimally invasive MSCT angiography. Via the right femoral artery a plastic tube was advanced into the aortic arch. Using a flow adjustable pump the radiopaque contrast agent meglumine-ioxithalamate was injected. Subsequent MSCT scanning provided an excellent anatomic visualization of the human arterial system including intracranial and coronary arteries. Vascular pathologies such as calcification, stenosis and injury were detected. Limitations of the introduced approach are cases of major vessel injury and cases that show an advanced stage of decay.  相似文献
