This article examines constraints in development bureaucracies in intensifying the use of microcomputers as they move beyond processing applications to analysing applications. The work is based on the experience of several ministries of the Government of Kenya. Processing applications involve throughput of data and are relatively simple. Analysing applications, in contrast, are more complex and include data assembly, sensitivity analysis, and modelling. The article argues that processing applications are more compatible with the administrative cultures, bureaucratic functions, personnel skill levels and organizational structures of development bureaucracies. Analysing applications are less compatible because they require a level of training and motivation uncommon in development bureaucracies. Analysing applications are further thwarted by constraints in the supply of relevant information and the lack of demand for analysis by decision-makers. A four-cell matrix is developed which explains these constraints. The article concludes with several recommendations for encouraging microcomputer-based analysis, but cautions that processing applications will continue to dominate for the foreseeable future.  相似文献

New York State experimented with replacing their litigation-oriented system for achieving toxic dump site cleanup with one promising to lower transaction costs through alternative dispute resolution. Our analysis of outcomes is informed by three generations of implementation work focusing on (1) the motivations and incentives shaping individual behavior, (2) the larger organizational and political factors associated with variation across cases, and (3) the generic properties of policy implements. This mosaic approach to explanation produces, we believe, a more lifelike picture of use to policy makers for understanding the dynamic and interrelated nature of their choices.  相似文献

The EPA implements its policy of exhaust emission control by setting standards specified in terms of grams of pollutants per mile traveled. As a result, the tax must first restrain the vehicle miles traveled (VMT) if it is to have an impact on emission at all. EPA's choice of miles traveled as the medium through which its policy of pollution control must run is unfortunate, because travel is an activity that people resist giving up. This is reflected in a low long-run price elasticity of travel demand. Consequently, it takes substantial increases in the gasoline tax to make an impact on long-run travel demand. Simulation results show that under an alternative policy option, where EPA's standards are specified in terms of grams of pollutant per gallon of fuel burned, the same long-run reduction in exhaust emissions achievable today can be achieved (at an even higher level of confidence) with less than one-tenth of the increase in gasoline price required under the existing policy regime.  相似文献

Newspaper juries     
This article reports on a field experiment on the effect of media information on people’s attitudes towards the justice system. For the duration of a year a Dutch local newspaper took small groups of readers, called ‘newspaper jurors’, to court sessions of criminal cases and subsequently reported on their experiences and perceptions. Using a quasi-experimental design, we examined whether an attitude change in the general reader population of this particular local newspaper occurred as a result of the jury’s newspaper reports. Findings show that, after the treatment interval of 1 year, no attitude change in the general reader population could be identified that was absent in the control group.  相似文献

We consider the contributions made by Robert H. Bork's Coercing Virtue (2003) and Anne-Marie Slaughter's A New World Order (2004) to the ongoing debate over the citation of foreign law in United States courts. While empirically minded sociolegal scholars might be tempted to dismiss these books as mere op-eds, that would be a mistake. Taken with the spate of other recent work, they supply the makings of an agenda for rigorous research devoted to understanding the exchange of law among nations.  相似文献

This article contributes to the development of theories on European integration by testing and exploring statistical models on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003. We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic models might be an interesting avenue for future conceptualizations of the EU integration process. This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to thank the seminar participants for useful comments.  相似文献
