Employment predictions in social impact assessment: An analysis of some unexplored variables

Social scientists investigating the impacts of energy development are increasingly searching for predictive models of the employment benefits to locals. This issue is of extreme importance not only because of the benefits to locals but because of the issue of local benefits as well as the connection with population growth and boom town development. Unfortunately, some of the recent investigations and predictive models are of little utility as a result of certain analytical and methodological faults, including improper assumptions about local labor supply and local preferences. In addition to the assessment of previous investigations, a framework for predicting local employment impacts is suggested. This framework utilizes characteristics and preferences of the local population.     

Alternative sources of technology: An analysis of induced innovations

This paper considers why firms differ in the degree to which they rely on their internal R&D organization for generating new technologies (induced innovations) rather than on existing external technology markets (purchased innovations). An empirical model is suggested to explan inter-firm differences in the percentage of new technology induced through R&D efforts. The analysis suggests that such differences are systematically related to the firm's size, its competative environment, and its degree of diversification.     

Henry George and Europe

A bstract . In the eyes of European scholars, publicists and politicians who studied Henry George's work, he, as a social philosopher , had adopted the position of the natural law philosophers of the 18th century. The latter inspired the Declaration of Independence, the U.S. Constitution and its Bill of Rights, as well as the poiitical philosophy of Jeffersonian democracy , the ethos of the 18th and 19th century pioneer settlers. George rejected Social Darwinism. He saw natural law as the only true and reliable basis for a just social order. Like Karl Marx he mastered Ricardian economics ; unlike Marx, George made two factors the basis of his system, labor and land. George saw that each person had a natural right —and a natural imperative for survival —to apply his or her productive capacity to the earth –as living space and as storehouse of nutrients and raw materials. The person-land relationship , he discovered, lay at the basis of human culture. And so the land's rent , now monopolized by the few, had to be appropriated to meet the needs of society, most efficiently and justly by a land value tax.     

Goal programming solutions to transportation problems with variable supply and demand requirements

This article deals with goal programming as an aid to resolving transportation problems. The objective of this study is to demonstrate the use of goal programming as an approach to reducing total cost in transportation problems that possess variable supply and demand requirements. A generalized goal programming model is formulated and applied to a series of transportation problem situations based on the empirical data provided by a medium-size trucking firm. Comparison of the results demonstrates the cost advantage of using the goal programming model in place of the transportation method and integer interval linear programming.     

Unplanned buying and in-store stimuli in supermarkets

Manufacturers and retailers in industrialized countries spend large sums on advertising and/or in-store promotion in the hope of increasing sales of their merchandise through ‘impulse’ buying. Results are reported in this paper of the unplanned buying behaviour of 450 consumers in 15 major supermarkets in South Africa compared with similar studies in the United States and the United Kingdom. The findings indicate that unplanned buying is higher in the United States than in South Africa, but that the importance of in-store stimuli holds true across cultures. Analysis of other variables such as brand loyalty, specific outlet, and presence of a shopping list is also reported on a cross-cultural basis.     

From skyhooks to walking sticks: on the road to nonrational decision making

The amount of information that should be processed to reach a rational solution is so vast that it overwhelms our limited memory and analytic capacity. To grapple at all with real problems, we must shrink them to mind size. As Nobel Laureate Herbert Simon has suggested, we must learn to "satisfice." Using examples and a case history of managerial succession, Agnew and Brown demonstrate the importance of nonrational factors in decision making. "Skyhooks," their first major concept, are composed of an individual's strong beliefs and biases that appear almost as acts of faith without any obvious foundation. They help the exceptional executive operate on a limited set of alternatives. But while skyhooks give direction, they do not provide the means to reach a destination. Simpler conceptual models, or "walking sticks," are necessary to cover the rocky trails. Agnew and Brown offer four walking sticks that can be applied to managerial succession problems. The first walking stick considers executive decision making in three parts--nonrational, semirational, and rational--and covers the conditions in which each component comes into play. The second helps examine human resources as fixed or fluid and as assets or liabilities to develop a schema for manpower accounting in executive succession. Playing vs. talking a good executive game is the topic for walking stick three. The concern here is to distinguish the real players--who can manage systems--from the mere talkers, who can manage only fragments of systems. The fourth walking stick draws on the law of resource gravitation and crystallization, a law with implications for trainers: You can't fashion management training to fit all comers; instead, you must tailor it to what the trainees already are and know.     

Calculating minimum and maximum possible variances from n-tile grouped data

Summary social science data are frequently encountered for which the raw data are unavailable and for which the standard deviations are unreported. This often precludes further analysis or even meaningful use of the summary data. At times, however, the published data include the means for different quartile, quintile, decile, or, in general, n-tile groups. This is particularly the case for income distribution figures, which will often report the average income of the bottom 20% of income units, of the second 20%, etc. We demonstrate here that when such submeans are known it is possible to calculate minimum and maximum possible values for the standard deviation or variance, which will then permit tests of statistical significance to be employed.
