AbstractTo support decision-makers considering adopting integrated pest management (IPM) cropping in Norway, we used stochastic efficiency analysis to compare the risk efficiency of IPM cropping and conventional cropping, using data from a long-term field experiment in southeastern Norway, along with data on recent prices, costs, and subsidies. Initial results were not definitive, so we applied stochastic efficiency with respect to a function, limiting the assumed risk aversion of farmers to a plausible range. We found that, for farmers who are risk-indifferent to moderately (hardly) risk averse, the conventional system was, compared to IPM, less (equally) preferred.

The main content of the article is currently concerned only with the problems of methodology and methodology of political forecasting: the ability to see political change adequately is one of the main conditions for the correct view of political management strategies and tactics, targeted influence on political processes. The article analyzes such issues as the strength and continuity of the "forecasting - planning - management" chain, as the most important factor in achieving current and long-term goals and objectives for the political subsystem, institutions, entities and society as a whole. It also analyzes the experience of developed countries in determining the status of forecasting efficiency analysis centers through their relations with various government agencies.

Economic growth has no paramount value for population health, and population health becomes a determinative of maintenance of economic growth. The economic efficiency analysis - not unique, but the important criterion for decision-making at investment of resources in actions for a mental health care as he allows to consider directly financial and scientific consequences of various actions. The generalized indicators of mental health of the population pay off with use of health indicators of population. Health indicators provide a correct methodological basis for measurement of various conditions of decrease in functioning which the individual throughout a life faces. One from the most used indicators is the indicator of years of a life adjusted for disability (DALY) is. On the basis of the described indicators there is a possibility to estimate economic efficiency of projects in social or non-productive sphere of economy which even in intermediate term prospect, without speaking about long-term, there can be not less profitable, than projects in industrial sphere.

This paper is a report on some early findings of a long-term study which has the ambitious objective of suggesting better alternative solutions to the general problem of controlling a collection of aircraft. The study aims to answer questions about the optimum division of responsibility between the aircrew and ground A.T.C., about the way in which the A.T.C. tasks are shared between a number of controllers and A.T.C. computers, and about the fundamental principles on which traffic flow is organized.
