An appropriate development strategy for Southern Africa∗

The limited successes achieved with development in the Third World and the national states in Southern Africa have necessitated a considerable change in development thinking and practice. The conventional developmental approach, which is based on growth models, is inappropriate for the conditions in the LDCs. A new development approach, coupled with an appropriate development strategy, has culminated in the development literature.

In this article the poverty problem in Southern Africa is outlined as a general background, whereafter the new development approach and a few guidelines for an appropriate development strategy is discussed. The application of the new strategy in the circumstances of Southern Africa is highlighted.     

Black americans and Ghanaians: Comparative patterns of internal migration

Conclusions For our purposes here, the analysis has been fruitful in that it has served to indicate and underscore in both general and specific terms the sources and determinants of migration movement and the destination of migrants. The qualitative analysis and the statistical test have led to several research conclusions. Both United States and Ghanaian migrants behave in accordance with the migration concepts examined. Common relationships between migration and economic opportunity are apparent. While push factors have generally initiated migratory movement among black Americans, particularly in respect to the South, both groups tend to move to regions with better economic opportunities. In both cases, migration is a negative function of distance, and a large labor force at the origin is a stimulus to out-migration at the origin.     

A utopian view of R&D functions

Technology management research appears to have a much longer history than is commonly assumed. In this short paper attention is drawn to some of Francis Bacon's writings which appeared in the early seventeenth century, and which contain ideas on laboratory organization that still have relevance today. In fact, it is only recently that the same broadness of laboratory functions described in the earlier text has been re–discovered.     

Estimating Bargaining Effects in Hedonic Models: Evidence from the Housing Market

Bargaining is common in markets for heterogeneous goods and differences in bargaining power between buyer and seller affect the negotiated transaction price. Previous research has found systematic evidence in the housing markets that weak buyers pay higher prices and weak sellers receive lower prices for their homes. Earlier work has modeled the bargaining effect as a parallel shift in the hedonic function, implicitly assuming that attribute shadow prices were unaffected by the bargaining process. In this paper, we use a sample of home sales where the seller's bargaining power is weakened by the fact that the home is vacant at the time of sale to test whether the effect of bargaining is best captured by a shift in the hedonic constant or whether the attribute shadow prices vary as well. The question is significant for property valuation where estimation of the marginal value of an attribute is commonly used to adjust comparable sales data. We find strong confirmation that bargaining power influences the negotiated price. We also find evidence that bargaining power alters attribute prices, although we do not find a consistent pattern across markets.     

The measurement of corporate portfolio strategy: analysis of the content validity of related diversification indexes

Measures developed for the analysis of corporate diversification have become fundamental to a broad range of strategy research. This paper examines the content validity of the two most widely used continuous measures of related diversification—the related component of the entropy index and the concentric index—and raises fundamental questions about their validity as indicators of portfolio relatedness. These questions are not driven by the use of SIC data for estimation of the indexes; they involve validity problems intrinsic to the construction of the measures. The related component of entropy and the concentric index are sensitive to features of corporate portfolio composition that may not be directly linked to portfolio relatedness. These sensitivities can create important ambiguities in strategy research. Copyright © 2002 John Wiley & Sons, Ltd.     

Wer wird Professor für Kommunikationswissenschaft und Journalistik?

Der vorliegende Beitrag fragt nach der demographischen Struktur der zentralen akademischen Akteure der Kommunikationswissenschaft in Deutschland und nach m?glichen Ver?nderungen dieser Struktur in den letzten 50 Jahren. Die Analyse zeigt zum einen, dass von einem einheitlichen Zugang zum Hochschullehrerberuf nach wie vor keine Rede sein kann, und zum anderen, dass das Fach vor einer demographischen Herausforderung steht. Die Kommunikationswissenschaft hat sich durch Akademisierung und ?Versozialwissenschaftlichung? von ihren Wurzeln gel?st. War Berufserfahrung im Medienbereich bis in die 1960er Jahre Voraussetzung für eine Berufung, verfügt heute nur noch eine Minderheit über solche Erfahrungen. Da die Existenz des Faches im Rahmen der Universit?t auch von der Nachfrage der Studierenden abh?ngt, kann man über die Folgen des anstehenden Generationswechsels nur spekulieren. In jedem Fall fehlt es an formal für die Hochschullehrerlaufbahn qualifiziertem Nachwuchs. Deshalb sind erhebliche Anstrengungen erforderlich, wenn der Boom im letzten Drittel des 20. Jahrhunderts sich nicht als Seifenblase erweisen soll.
