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.     

Fish protein concentrate: Lessons for future food supplementation

Fish protein concentrate (FPC) was widely publicized during the late 1960s as the most promising of a number of ‘technological fixes’, to eliminate worldwide malnutrition. On the basis of their deep involvement in a study on the fate of FPC projects in over 40 countries, the authors speculate in this paper what lessons should be learned from the FPC experience for future food supplementation endeavours.     

Dynamics of food policy formulation in the USA

Examination of the dynamics of food policy formulation in the USA reveals a series of intriguing contrasts. As an example of pluralist decision making, it is unequalled in the sheer number and variety of actors and interests which it encompasses. This article analyses four principal generic elements of the food policy process: its ideological underpinnings; its policy settings; its substantive components; and, its foreign-domestic linkages. The profound changes which have occurred in the Washington political climate are also considered in terms of their implications for food-related policies in both the domestic and international arenas.     

Beyond Profitability of Energy-Saving Measures—Attitudes Towards Energy Saving

Private homeowners can save considerable amounts of energy and money, if they retrofit their homes according to up-to-date energy efficiency standards. From an expert point of view, many of these technical measures are profitable in relatively short payback times, if only additional costs are considered. Apparently, many homeowners do not follow this type of rationality and do solely not regard their refurbishment as an investment. Drawing on the results of an empirical survey of retrofit activities among 1,008 homeowners in Germany, it is argued that refurbishments are the outcome of a broader decision which is shaped by an alliance of economic and non-economic motives and goals. Energy-saving measures is expected to lower the burden of operating costs in a perceptible way and secure the value of the house, but they must also correspond to needs like comfort, convenience or belonging in order to be realized.     

Does Neutral Stability Imply Lyapunov Stability?

A central concept in evolutionary game theory is that of an evolutionarily stable strategy. However, many games of interest for economics have only strategies which meet the weaker requirement of neutral stability. While neutral stability implies Lyapunov stability under the replicator dynamics in pairwise interactions, we give here an example in which an evolutionarily stable strategy is not Lyapunov stable in a more general context. We propose to use instead the notions of (strong) uninvadability and (strong) unbeatability, refinements of evolutionary and neutral stability, respectively. Strong uninvadability implies asymptotic stability, and strong unbeatability implies Lyapunov stability under the replicator dynamics. Journal of Economic Literature Classification Number: C72.     

Targeting and political support for welfare spending

This paper investigates the political support for social assistance policies in a model in which incomes are stochastic (so that welfare policies have an insurance benefit) and unequal ex ante (so that welfare policies have a redistributive effect). With self-interested voting, narrow targeting may so reduce the probability of receiving benefits for the majority that the majority prefers to eliminate benefits altogether, even though the cost of narrowly targeted benefits is close to zero. In contrast, a majority of self-interested voters always supports positive welfare benefits when the policy is targeted sufficiently broadly. If voters are somewhat altruistic, the impact of targeting on political support for welfare spending diminishes but does not disappear. Received: July 1999 / Accepted: May 30, 2000     

The world food council at three years: Global food system manager?

Analyzing the results of the World Food Council's Third Ministerial Session (Manila. 1977), in terms of both substance and procedure, the authors discuss the Council's current role in international food policy making. It appears that the final communique from Manila, as well as the improved policy making processes begun there, point to a strengthened and more positive position for the Council in the future, as an advocate, catalyst and coordinator of action to alleviate global hunger.     

Foreign—domestic intersections in US food policy

This essay probes the major points. of intersection between US domestic and foreign policies in the realm of food and agriculture. Five issue areas are of specific interest: the farm income/consumer price/food supply matrix; international agricultural trade relations; economic, strategic, and diplomatic applications of food resources; LDC agricultural development and global food security; and food assistance.
