Egypt and the enlargement of the EEC: Impact on the agricultural sector

This article examines the impact of the second enlargement of the EEC on the agricultural sector of Egypt. The authors consider the impacts on Egypt's agricultural trade and, through the use of a linear programming model, the long term impacts of EEC enlargement. The authors conlude that, in short run, the southward expansion of the EEC will impose only a limited additional burden on the Egyptian economy. But, in the long run the burden placed on Egypt by increased protectionism in the expanded EEC could be much more severe.     

R & D expenditures and import competition: Some evidence for the U.S.

Zusammenfassung F & E-Ausgaben und Importkonkurrenz. Einige Befunde für die USA. - Die Verfasser untersuchen den Einflu? der Importkonkurrenz auf die F & E-Aktivit?ten der amerikanischen Industrie. Die theoretische Diskussion deutet daraufhin, da? eine verst?rkte Importkonkurrenz die F & E-Ausgaben nur in hochtechnologischen Industriezweigen erh?ht, w?hrend Industrien mit geringerer Technologie wahrscheinlich als Antwort andere Strategien w?hlen. Der empirische Befund für die Jahre 1972-87 scheint diese Annahme zu best?tigen.

Résumé Des dépenses pour la R & D et la concurrence de l’importation: Quelques preuves pour les Etats Unis. - Dans cette étude les auteurs examinent l’effet de la concurrence de l’importation sur l’activité de R & D dans l’industrie américaine. La discussion théorique propose qu’une intensification de la concurrence de l’importation augmenterait les dépenses pour la R & D seulement dans les industries d’une technologie supérieure tandis que les industries d’une technologie inférieure probablement choisiraient une réaction différente. Les preuves empiriques pour les années 1972 à 1987 semblent confirmer cette proposition.

Resurnen Gasto en I & D e importaciones competitivas: alguna evidencia para los EE UU. - En este trabajo se investiga el impacto de importaciones competitivas sobre la actividad de I & D en la industria de los EE UU. La discusión teórica sugiere que un aumento de la competencia por parte de las importaciones podria elevar el gasto en I & D de las industrias de tecnología avanzada, mientras que en las industrias de menor nivel tecnológico la respuesta podría ser diferente. La evidencia empírica para los a?os 1972–1987 parece confirmar esta propositión.

Enterprise Mashup Systems as Platform for Situational Applications

Currently, several Enterprise 2.0 platforms are beginning to emerge. This paper introduces Enterprise Mashup technology as a means to improve IT alignment of individual work processes and changing business needs. Enterprise Mashups enable users to create customized applications to easily find and transform business information and functionalities, as well as collaboratively share pre-built Mashup applications. Therefore, the concept of Enterprise Mashups integrates Web 2.0 technologies and principles with well-established paradigms such as Enterprise Information Integration, Business Intelligence, and Business Process Management. Involved organizational key drivers, technical challenges and inhibitors are discussed to assess the potential business value and explain the emerging expansion of Mashup platforms in companies.     

Rethinking Urban Epidemiology: Natures,Networks and Materialities

How should we understand the relationship between urban environments and infectious diseases? This article addresses this question from three particular perspectives: that of the materialities of health, that of nature and that of networks. The first perspective analytically blends biological dynamics, environmental influence and social practice. The second perspective, mainly influenced by multispecies ethnographies, foregrounds the liveliness and unboundedness of cities. Finally, the third perspective analyses how health is drawn into the domain of security. The article argues that while globalization and urbanization are often discussed as having triggered the emergence and spread of pathogens, urban epidemics are not self‐evident and ‘natural' consequences of these pro‐cesses. They do not fall neatly into universal categories of space, modernity or risk; rather, they are produced and shaped by a range of social, political, biological and economic sites and scales. Accordingly, the emergence of pathogens depends on its articulation through specific analytical frameworks. This article suggests that a critical focus on how infectious diseases manifest themselves differently in different local contexts may not only provide insights into the manifold forms of urban life, but also into the multiple, complex and highly political constitution of health.
