The windshield method of questionnaire distribution: A viable alternative

A variety of data collection methods are available for survey research. Basic distribution techniques differ in cost, administrative ease, and characteristics of returns. The authors discuss the relative advantages and disadvantages of distributing questionnaires by placing them on the windshields of patrons' automobiles. This method of distribution appears to be preferred for certain types of shopper surveys.     

Urgency of trade reform over trade liberalisation

The GATT system has in recent years revealed a number of dangerous weaknesses. Therefore there is reason for concern not only with the further liberalisation of trade within the accepted framework of GATT rules but with a reform of the rules as well.     

The application of a Markov Chain in educational planning

Mathematical models can assist educators in the preparation of their educational plans and their potential in this regard is being increasingly realized. As a result, models have found application at all levels at which planning is conducted.This paper examines the potential of one model—the Markov Chain—which is capable of predicting enrolments for an education system.The model is applied to the New South Wales State Government education system between 1947 and 1961 and the projected enrolments compared to the actual enrolments in those years.Some success is achieved but it appears as if the data rather than the model are responsible for this. The limitations of the Markov Chain approach are discussed and present research and directions listed.
