The purpose of this paper is to evaluate the causes of the apparent failure of black parents to pass their status advantages along to their children. The black-white differences in status transmission found by Duncan are discussed, explaining his findings by means of the Wisconsin model of status attainment. To explain the lesser dependence of the…

A general Computer program is described that will compute asymptotic standard errors and carry out significance tests for an endless variety of (standard and) nonstandard large-sample statistical problems, without requiring the statistician to derive asymptotic standard error formulas. The program assumes that the observations have a multinormal…

The Monte Carlo method was used, and the factors considered were (1) level of main effects in the population; (2) level of interaction effects in the population; (3) alpha level used in determining whether to pool; and (4) number of degrees of freedom. The results indicated that when the ratio degrees of freedom (axb)/degrees of freedom (within)…

Campbell (l969) argued for the interrupted time-series experiment as a useful methodology for testing intervention effects in the social sciences. The validity of the statistical hypothesis testing of time-series, is, however, dependent upon the proper identification of the underlying stochastic nature of the data. Several types of model…

This paper discusses discrepancies between the observable labor market and the idealized world which is assumed in theory. The proposed solutions are focused on the development of an empirical model applicable to data on prime-age males from the Michigan Panel Study of Income Dynamics, but the author notes that many of these issues are relevant…

Mathematical models have been used extensively to describe the judgmental processes and strategies of individual decision makers, but rarely have the procedures been extended to describe the judgmental strategies of decision-making groups. The present study attempts to extend the procedures for the purposes of describing group decision-making…

An econometric model is formulated that explains income per person in various compartments of the labor market defined by three main levels of education and by education required. The model enables an estimation of the effect of increased access to education on that distribution. The model is based on a production for the economy as a whole; a…

Reviews arguments for and against the use of analytical modeling systems in higher education and presents findings of a national survey of user perceptions of frequently used modeling systems: CAMPUS, PLANTRAN, RRPM, and SEARCH. Concludes greatest needs are for user education, feedback to model builders, and institutional commitment to…

Discusses the status of modeling efforts to predict impact of different educational access and support policies and identifies pitfalls involved in using simulation models for state and national educational planning. Concludes that few goals held for large-scale models have been achieved. Points up needs for improvement, e.g. more information at…

Noting the disappointing results of past experimentation with computer modeling technology in higher education, the author discusses developments which promise potential: communication between model builders and users, interaction between large- and small-scale models, interface with operating data systems, emphasis on outcomes, and continued…

Examines simultaneous equation models, using a large national sample of women in their mid twenties: it is found that the number of children a woman plans to bear has only a small effect on intentions to participate in the labor force, although a woman's plans to participate in the labor force has a substantial effect on the total number of…

Four techniques for assessing differences between least-squares estimators of regression coefficients from group and individual-level data are summarized. The utility and suitability of all four approaches are discussed when (1) data are grouped by a nominal characteristic; (2) there are multiple regressors; or (3) individual-level data cannot be…

Historical regression uses the assumption that without intervention, growth at post-test will proceed at the same rate as at pre-test. Several methods of historical regression are compared with an illustrative example. (JKS)

The influence of financial considerations on college enrollment rates is demonstrated in an economic theory model incorporating both investment and consumption reasons for attending, with relevance to the theory of occupational choice. (MF)

Flow-diagrams, algorithms, decision logic tables, and concept maps are presented in detail as methods for teaching practical procedures, problem solving, and basic concepts in microbial genetics. It is suggested that the flexible use of these methods should lead to an improved understanding of microbial genetics. (Author/MA)
