Stabilization of export proceeds in Tropical Africa

Egner, Edward Brian January 1964 (has links)
This study contains an attempt to define and analyse the elusive concept of "stabilization"' in its application to the export production of countries in Africa south of the Sahara. The writer has found it hard to place his analysis in a specifically African context. This difficulty arose partly from the lack of data and the paucity of general reference works based upon African economic conditions. But it was also due to his desire to treat the subject of stabilization against a broad background of the social and economic factors which typically bear upon policy-making in Africa. The Introduction contains a methodological discussion of the means by which an economic analysis might take explicit notice of African social, political and administrative conditions. The conclusion is reached that it is impossible to blend all these factors into one analysis. The primarily non-economic background material is therefore consigned to Chapters I and II, with the discussion of the main theme following in Chapters III and IV. Chapter I contains five numbered sections. (l) The reader is introduced to the newly-independent 'Country X', an expositional device for lending coherence to material drawn from several different African countries. (2) Under the heading 'Political Factors’ there is a discussion of Pan-Africanism and of the "Mobilization' form of political organization. (3) Under 'Social Factors', there are brief outlines of several representative social problems, followed by an interpretation of the economic rationales underlying the 'hoarding' of cattle and the 'extended family system'. (4) Under 'Public Administration’ are discussed standards of morality in public affairs and the need for eliminating bureaucratic rigidities. (5) The summary points to the "confused and confusing" general situation in "X", and enjoins caution and a "piecemeal" approach to the application of economic theory. Emphasis is placed upon the social disruption which inevitably attends economic development of primitive societies. In Chapter II, to illustrate the importance of social and political factors in economic policymaking, there are brief reviews of three questions. (l) The use of psychological indoctrination to speed economic development. (2) The prospects for comprehensive planning in the light of the physical and conceptual difficulties experienced in compiling statistics. (3) The "export-bias" doctrine, Hlla Myint's refutation, and his alternative formulation. The conclusions are broadly similar to those of Chapter I. Chapter III analyses the case for a general international commodity price stabilization scheme. Following a review of the supply and demand factors responsible for the present pattern of international trade, it is concluded (a) that such a stabilization scheme would be administratively, politically and economically unworkable. (b) that the proposal is essentially one for achieving disguised income transfers from rich to poor countries, and (c) that stabilization of producer prices can equally well be achieved by domestic action. The discussion of domestic stabilization policy in Chapter IV centers upon the marketing of Ghana cocoa. The ambiguities of stabilization, which may refer to different periods of time, and to either prices, money incomes or real incomes are fully discussed. The effect of low prices upon production incentives is treated at length, as is the use of the stabilization authority to extract "forced savings" from peasant producers. The conclusion is generally in favour of national stabilization schemes, provided their objectives are strictly defined. Chapter V summarizes the conclusions already set out for the preceding chapters. / Arts, Faculty of / Vancouver School of Economics / Graduate

Some effects of biological and physical processess on soil aggregate stability

Molope, Mishack Bochankge January 1985 (has links)
The effects of biological and physical processes on the aggregate stability of some weakly structured arable and pasture soils were investigated. Preliminary investigations showed significant correlations between soil organic matter and both wet sieving and turbidimetric methods of aggregate stability; the latter method was chosen on grounds of convenience. Scanning electron microscope pictures showed the presence of both fungi and bacteria when soils were incubated. Growth of fungi, estimated by ergosterol measurement, correspond to temporary stability increases, which could be explained by retention of soil particles within the reticulum of fungal hyphae. The effect disappeared as the fungi were destroyed and replaced by bacteria and actinomycetes. Effects caused by fungi were examined separately, using vancomycin to inhibit bacterial growth, and bacterial effects by using cycloheximide to eliminate fungi. Bacterial growth had little direct effect in stabilising soil aggregates; periodate oxidation showed that polysaccharides produced by bacteria are mainly responsible. To examine the contribution of physical processes to increased stability in remoulded soils biological processes were eliminated by sterilisation. Thixotropic changes made a contribution to age hardening in remoulded aggregates similar in magnitude to biological processes. Thixotropic changes were reversible and accompanied by soil strength and metric water potential changes. Polysaccharides did not contribute to thixotropic aging processes. Remoulded soils were subjected to wetting/drying and freezing/thawing cycles. After 3 to 6 cycles the stability of both sterilised and unsteriliserd soils recovered to that of natural aggregates, suggesting a contribution by thixotropy. Repeated weathering cycles decreased the stability of unsterilised, and more so sterilised, field aggregates suggesting that in the former, bond reformation due to biological activity counteracted the destruction caused by wetting/drying and freezing/thawing.

Administrative and policy problems of wage stabilization under the Defense Production Act of 1950

O'Toole, Joan Laura January 1956 (has links)
Thesis (M.A.)--Boston University / I. History and Basis of Wage Stabilization The first effort in the history of this nation to establish a comprehensive wage control program was taken during World War II. It was not,however, until several months after the outbreak of hostilities that the President saw fit to ask Congress for special powers to permit him to initiate a wage control program. During the interim, wages were maintained at a stable level by the appeal of the President to labor and management to hold the line. Authority to begin the program of wage and price control was given the President in the Emergency Price Control Act of 1942 and subsequently the National War Labor Board was established. The wage control function during World War II was handled by several administrative groups and finally was vested in the National Wage Stabilization Board, whose function concerned the stabilization of wages and salaries and the settlement of certain labor disputes. The war in the Pacific ended with the N.W.S.B. functioning as the single wage stabilization agency. Following a brief transition period all such functions were either terminated or vested in the Secretary of Labor, and the N.W.S.B. was dissolved [TRUNCATED].
