Africa and The Global System Disaster

Abstract: The study proposes a critical review of the national modernization project on which every African country embarked as from 1960. Beyond the number of variants of this project based on the social content of the national liberation movement and the development strategy options implemented, the author reviews what he considers to be their common denominator, applicable to the entire third world for the whole post-war (1945-90) period which he calls the Bandoung period. He describes it as a bourgeois project, although there is no real national bourgeoisie: an attempt to build “capitalism without capitalists”. He then proposes a list of its achievements, on the basis of his own criteria, that of national construction and those of the populism of some experiences. He also proposes a classification based on the supreme criterion of the logic of capitalist globalization, that of the capacity of new industries to be competitive on world markets and explains Africa's failure from this standpoint by the delay caused by colonization in solving the agricultural problem. In the light of these considerations, he reviews the nature of the challenges raised today by globalization and outlines the main features of the transformations required in the design of national and regional policies and in the organization of the world system which could sustain a new departure for Africa. Résumé: L‘étude propose une lecture critique du projet national de modernisation dans lequel l'ensemble des pays africains se sont engagés à partir de 1960. L'auteur examine, par delà la variété des variantes de ce projet tenant au contenu social du mouvement de libération national et aux options de stratégie de développement mises en oeuvre, ce qui lui apparaît constituer leur dénominateur commun, caractéristique de toute la période de l'après guerre (1945-90) pour l'ensemble du tiers monde. II qualifie cette période de Bandoung. II catalogue ce projet de bourgeois, en dépit de l'absence d'une véritable bourgeoisie nationale, et l'analyse comme une tentative de construction “d'un capitalisme sans capitaliste”. II propose ensuite un bilan de ses réalisations, sur la base de ses propres critères, celui de la construction nationale et ceux du populisme de certaines expériences. II propose également un classement fondé sur le crière suprême de la logique de la mondialisation capitaliste, celui de la capacité des industries nouvelles de faire face à la compétition sur le marché mondial et explique l’échec africain de ce point de vue par le retard que la colonisation a apportée à la révolution agricole. A à lumière de ces considérations il examine la nature des défis que la mondialisation constitute aujourd'hui et brosse les grands traits des transformations que s'imposent dans la conception des politiques nationales et régionales et dans l'organisation du système mondial, susceptibles de soutenir un nouveau départ de l'Afrique.     

Ethical perceptions of Asian managers: evidence of trends in six divergent national contexts

Global link building is having a substantial impact in every sphere of Asian managerial activity. The economic upheavals of the Asian ?nancial crisis have cast a long shadow, and ethical clarity has become a social issue. For instance, corporate performance in terms of long-term survival, growth and global competency is seen to depend to a considerable extent upon the ethical infrastructur of managers and emerging managerial culture in Asia. One ?eld in which Asian managers and their managerial practices are often considered weak is the area of ethical clarity. Corporate managerial leaders in Asia need to develop new responses to the ethical complexities arising out of the increasing global interfaces. In spite of a growing awareness of the importance of ethical centrality in an intensely competitive international business arena, very little empirical work has been conducted to strengthen the relevant management literatures. The purpose of the research reported in this paper was to examine the perceptions of ethical probity among managers in six Asian countries. The results of the study indicate interesting convergences and divergences across countries and organisational demographies. The ?ndings lead to observations of the apparent similarities of ethical conceptualisation in global, societal and often in the organisational arena while revealing noticeable divergences in the domain of individual ethical perceptions.     

A Multi-Agent Model for Overlapping Negotiations

In the last few years, research on multi-agent systems has addressed different aspects of intelligent negotiations using methods developed in different domains including game theory, decision theory, and economic models. The research proposed in Andersson and Sandholm (1999), Sandholm (1993), Sandholm and Lesser (1995) and Aknine et?al. (2004), Aknine (2002) are significant examples. However, only some of this work focuses on problems related to complex negotiations, particularly those concerning new generation applications. This new research raises fundamental difficulties we have encountered, especially in overlapping negotiations and combined negotiations. This article is interested essentially in overlapping negotiations, which include several agent roles in a same negotiation. One or more agents may play each of these roles. This work shows that the high-level negotiation models are necessary in order to control the execution of overlapping negotiation processes, since, in these negotiations we are facing both classical problems of multi-agent negotiations based on two agents’ roles and the problems concerned with the interdependence of these negotiations. Synchronization of these different processes is thus necessary because of the multiplicity of the roles. Thus, this paper presents a formalized negotiation model, which deals with this problem. It gives a theoretical analysis of the suggested model and discusses the results of the experimental evaluation. To perform this evaluation, we use the application of intelligent service agencies on the Internet.     

A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.     

Are consumers' financial needs and values common across cultures? Evidence from six countries

Are consumers' financial needs, and financial values, the same or different across cultures? Two studies, with student (Study 1; n = 988) and non‐student (Study 2; n = 959) participants, explore the extent of equivalence, across six countries (Brazil, Russia, China, Taiwan, Tunisia and US), in financial need belief, and financial value, measurement models. The financial need beliefs, derived from self‐determination theory (SDT) principles, include financial self‐efficacy, financial autonomy, financial community trust and support; the financial values include materialism and financial altruism. Both the financial need and financial value constructs evidence configural invariance (similar factor structure), and factor invariance among student but not non‐student samples. The financial need constructs evidence full, and the financial value constructs evidence partial, metric (factor loading) invariance. Factor covariance invariance obtains for the financial need beliefs constructs but not the financial value constructs. Finally, neither financial need nor financial value constructs evidence scalar (intercept) invariance. These results provide partial support for extending SDT's hypothesis of universal human needs to the financial domain. In contrast, the financial value constructs of altruism and materialism are largely instable across cultures, suggesting that consumer views of giving, and the role of wealth in social status, differ between countries.     

The impact of external forces on cartel network dynamics: Direct research in the diamond industry

This paper describes the impact of external environmental forces on cartel networks. Using a case research approach, this report examines two leading business networks within one industry, over time. The results suggest that (a) bargaining power of intermediaries increases with the advent of new and powerful actors, (b) process activities that cartels previously controlled are being outsourced to new actors sometimes based in developing countries, (c) other actors are acquiring resources once dominated by a cartel, (d) external forces triggered by the illegal diamond trade, such as international regulatory constraints, no longer favour cartels like De Beers, and (e) over time, these and additional environment factors are forcing actors like De Beers who perform rigid process activities to become more flexible. For example, forces are moving cartels which relied previously on hand-picked intermediaries in highly controlled networks to market their products to adopt a flexible market-focused expansion of operations in retail contexts.     

Smallholder participation in vegetable exports and age‐disaggregated labor allocation in Northern Tanzania

Modern agricultural supply chains have been playing an increasingly important role in developing countries and have had significant effects on rural labor markets. This article analyses the effects of smallholder farmer participation in export vegetable supply chains in Northern Tanzania on both household hired labor demand and off‐farm labor supply, using an age‐disaggregated approach. In our sample, neither separability nor exogeneity of smallholder farmer participation in export supply chains can be rejected. Hence, we apply lognormal double‐hurdle models and find that participation in export supply chains positively affects households’ decision to hire labor from all age groups. We also find that it increases the unconditional overall level of hired labor demand, while the age‐disaggregated analysis shows that these effects mostly benefit rural youth. However, our sample does not allow us to establish statistically significant evidence of an effect on household off‐farm labor supply although the point estimates point to nonnegligible positive effect sizes.     

Return predictability of variance differences: A fractionally cointegrated approach

This paper examines the fractional cointegration between downside (upside) components of realized and implied variances. A positive association is found between the strength of their cofractional relation and the return predictability of their differences. That association is established via the common long-memory component of the variances that are fractionally cointegrated, which represents the volatility-of-volatility factor that determines the variance premium. Our results indicate that market fears play a critical role not only in driving the long-run equilibrium relationship between implied-realized variances but also in understanding the return predictability. A simulation study further verifies these claims.
