Statistical estimation of socio-economic factors affecting migration in W. Europe

A statistical estimation of the relationship between socioeconomic factors and net international migration in Western Europe from 1977 to 1980 is presented using data from the Monthly Bulletin of Statistics and the Statistical Yearbooks of the United Nations and each country. It is found that the rate of change in the gross national income, the percentage of the gross national income in the tertiary sector, and the number of automobiles per 1,000 inhabitants are the major factors affecting net migration in the most industrialized countries of Western Europe.     

The impact of emigration on national development in the Arab region: the case of the Yemen Arab Republic

"The focus of this article is the impact of emigration on national development in labor sending countries experiencing wide-scale emigration, the main contention being that, due to the characteristics of contemporary labor movements among Arab countries, there obtains a contradiction between short term benefits and long term adverse effects. The article briefly defines development, then presents empirical evidence from the Yemen Arab Republic of the negative impact of labor emigration."     

An innovative approach to selecting an executive director

As a guide for how to select a new executive director, a family agency adopted the search committee process from higher education.

On the limiting properties of social indicators

Characteristics of the population and economic measures that constitute traditional social indicators are compared with more recent “quality of life” measures to demonstrate that social indicators are always value statements at the policy level. The possibility of alternative perspectives is illustrated. It is suggested that an awareness of the assumptions implicit in any given indicator is as important as the data they provide.     

A METHOD FOR SOLVING LINEAR PROGRAMS WITH VARIABLE RESOURCES

This paper is concerned with the solution of linear and linear goal programming problems in which the values of the right-hand side parameters are not fixed constants. Specifically, we are concerned with linear optimization problems in which the right-hand sides of the constraining equations are free to vary subject to a set of linear constraining equations. By formulating a relaxed linear program wherein the right-hand sides are treated as variables, we show how it is possible to solve one larger linear program that yields as a solution not only the optimal values for the decision variables, but also the optimal values for the right-hand sides.     

PSYCHOLOGICAL DETERMINANTS OF BOUNDED RATIONALITY: IMPLICATIONS FOR DECISION-MAKING STRATEGIES

In this paper the implications of cognitive strain for decision-making effectiveness are explored. Literature concerning the psychological processes of decisionmakers which underlie the operation of cognitive strain and which predispose them to the effects of cognitive strain, is reviewed. Next, the impact of cognitive strain on narrowly constraining or “bounding” rational decision-making is examined, and the choice strategies of satisficing and incrementalizing are criticized as failing to broaden the bounds of rational decision-making. Finally, elements of an eclectic choice strategy designed to assist decision-makers handle the informational demands of complex decision problems are discussed.
