Generalized least squares estimators in the analysis of covariance structures

Abstract: Let S represent the usual unbiased estimator of a covariance matrix. ?o, whose elements are functions of a parameter vector ?o:?o = ?(?o). A generalized least squares (G.L.S.) estimate, ?. of ?o may be obtained by minimizing tr[ {S - ?(?) }V]2 where V is some positive definite matrix.

Black consciousness in South Africa

Abstract: South African concept. Black consciousness is vaguely defined and contradictions exist in respect of its philosophical bases and objectives. The relative contributions of the cultures of Indians and Coloureds appear to be slight and African culture dominates. There is no doubt about the existential nature and political objectives of the movement Black consciousness and human relations. In spite of denials by leading exponents, racism underlies much of Black consciousness thought, and there is complete withdrawal from Whites and White institutions. The South African Students’ Organisation and the Black Peoples Convention – both organisations adhering to the ideals of Black consciousness – discourage their members from participating in South African government created institutions. Religious involvement. The viewpoint that theology is concerned with existential problems led to its political involvement and the belief that religious fulfilment can only be achieved together with or after fulfilment i...

The relative importance of the deuteron wave function and the phase shift for the triton

Abstract: It is shown that for separable potentials of rank two fixing the deuteron wave functions makes the triton binding energy insensitive to both the on-shell and off-shell T-matrix elements down to E/sub lab/ approx equal 20 MeV. It is concluded that the deuteron wave function and the low-energy phase shift are the determining factors for the triton binding energy, and that the deuteron wave function is of greater importance than the phase shift.

Business Strategies for Political Action

Abstract: It is the objective of this article to use a political approach to business strategy formulationwhere political is interpreted in terms of the following definition of politics:Politics is a process which takes place when one or more actors attempt to structure a situation in such a way that their individual goals are promoted. The term 'actor' is used here so as to mean an individual, a group, an organisation or even a nation. If the definition is acceptable then the firm can most certainly be viewed as a political actor, since it will strive to create conditions in its environment and to restructure the environment so that the people and the organisations it interacts with will behave in ways that the firm desires. The question one naturally asks is why a political approach to strategy is suggested. It is felt the current theoretical approaches to business strategy fall short in two respects. First, they tend to concentrate heavily on the "commercial" aspects of strategy formulation devoting attention predominantly to product/market considerations. Second, they tend to ignore the political implications of actively attempting to restructure the environment so that the firm's own goals are promoted. In practice, top managers are fully aware of these shortcomings and in fact do formulate informal political strategies. In this

South African soil conservation legislation

Abstract: The main feature of the Act was that it provided in a de mocratic spirit a basis for co-operation between the State and the farming community with a view to soil conservation and the stimulation of conservation farming.

The Sectional Titles Act and the Wohnungseigentumsgesetz

Abstract: This article consists of three parts. In the first part the reasons for introducing the Wohnungseigentumsgesetz will be compared with those which led to the introduction of the Sectional Titles Act. The aim of this comparison is to provide a background for certain peculiar provisions of each statute. In the second part the dogmatic construction of both statues, which also accounts for certain specific provisions, will be compared. In the last section a comparison will be drawn between the ways in which certain particular aspects are regulated by the two statutes.

Plant-Ecological Significance of the Soils of the Central Orange River Basin

Abstract: Field observations made during a reconnaissance soil survey of the Central Orange River Basin for the Orange River Development Project, showed significant relationships between soil landscapes and associated vegetation. Although no intentional ecological studies were made it was clear that certain soil types (soil forms and/or series) are always associated with particular plant communities. In view of this general consistent soil-plant relationship observed in the survey area, it is reasoned that apart from climatic and topographic factors, the soil should in future be taken into consideration in defining and mapping of veld types.
