For most tests administered with time limits some examinees complete all items while others do not. It is often useful to know what the distribution of items completed would be if the number of items on the test were much larger. It may also be of interest to estimate the correlation between working speed, as measured by the number of items…

The purpose of this study was to determine if there were any systematic differences in intellective factors between graduates and non-graduates in the associate degree programs that may be useful for improving the selection process. Ten predictor and eight criterion variables were measured for all associate degree freshman classes at the college…

Phase I of Northern California Cooperative Research Project on Student Withdrawals (NORCAL) examined withdrawal and continuing students in 23 colleges, evaluated the data, predicted potential withdrawals, and summarized findings. A questionnaire was used to help develop a model to predict attrition within the first term of enrollment. The junior…

Twelve papers dealing with the meteorological aspects of air pollution were translated. These papers were initially presented at an international symposium held in Leningrad during July 1968. The papers are: Status and prospective development of meteorological studies of atmospheric pollution, Effect of the stability of the atmosphere on the…

Fifteen papers were translated: On the removal of impurities from the atmosphere by clouds and precipitation; Some aspects of the adoption of automatic methods of determining atmospheric pollutants; Recording of sulfur dioxide content at the outskirts of a city. Comparison of measurement results for a valley and an elevation; Theoretical and…

Ten papers were translated: Maximum permissible concentrations of noxious substances in the atmospheric air of populated areas; Some aspects of the biological effect of microconcentrations of two chloroisocyanates; The toxicology of low concentrations of aromatic hydrocarbons; Chronic action of low concentrations of acrolein in air on the…

This study used the Delphi technique to determine degrees of consensus on the future of teacher education. The panel of experts was comprised of 40 chief administrative officers or their representatives in the English-language teacher education institutions in Canada. In Part I of the study, each of the 40 panelists was provided with 20 statements…

Traditional methods of studying organizations have made useful contributions to our understanding of the relationship between formal structure and technology, but they still need to be supplemented. Comparative analysis, for example, maintains a formal, empirical tradition but is conducted at a highly aggregative level. The "constituent"…

A model of attitudes change having the mathematical characteristics of a hyperbolic function, with major parameters determined by source credibility and discrepancy, is proposed and tested against leading established models of attitude change. The proposed hyperbolic model proved to be a more accurate predictive device than either of the two…

A standard operating procedure (SOP) is presented for calculating the date of freeze-up on the St. Lawrence River at Massena, N.Y. The SOP is based on two empirical temperature decline equations developed for Kingston, Ontario, and Massena, N.Y., respectively. Input data needed to forecast freeze-up consist of the forecast December flow rate and…

The author discusses the use of hierarchical tests with learning disabled (LD) children and presents four examples to explain basic characteristics of this type of test. It is explained that a hierarchical measurement provides two associated scores - a composite score and an error of prediction score. The examples are used to portray the use of a…

Monte Carlo simulation techniques use multiple values in the form of probability distributions for input variables and generate a distribution of possible futures. This article explores some of the implications of adopting a probabilistic approach to planning over the more conventional deterministic approach. (Author/IRT)

Describes a training cost model used in government agencies to simulate the behavior of training costs and thus predict or reconstruct the costs of a training course. Includes step-by-step procedures for using the model, worksheets, and charts. (MF)

Some questions about the relationship between program evaluation and forecasting are raised. Contrasting the two fields in terms of mind-set, purpose, problems, advantages, and use shows that although their modes of inquiry are indeed very different in many ways, there is interdependence between the two in several areas.

Proposes a probabilistic mechanism to describe various forms of the Bradford phenomenon reported in bibliographic research. The inclusion of a time parameter in the model to allow predictions of dynamic systems is explained. (58 references) (CLB)
