Brown University A Population Studies and Training Center has been established. The Center will integrate the varied demographic and ecological activities conducted by Department me~berswith the extensive training program m demography which has been developed since 1950. Sidney Goldstein Chairman of the Department will serv~ as director of the Center. Dr. Harold Organic has been appointed research director with specific responsibility for establishing the Population Research Laboratory. The Laboratory will maintain its own sample survey facility for use by faculty and advanced graduate students and will undertake a seven-year longitudinal study of the correlates of changes in the demographic and social structure of the population. This project is supported by a research grant from the Public Health Services for the establishment of a Population Research Laboratory. Professor Robert G. Burnight will serve as training director under a grant to support graduate students specializing in demography. Dr. Sudhir Sen, representative of the United Nations Development Program in Yugoslavia, will serve as a visiting professor under a National Science Foundation Senior Foreign Scientist Fellowship. Professor Basil G. Zimmer has returned from a year's leave of absence devoted partly to fertility research at the University of Aberdeen, Scotland. Alex M. Burgess, Jr., M.D., has been appointed Research As-
This paper presents an explanation of how FORTRAN was used to write a list-processing language, DYSTAL, which uses linear arrays rather than linked word lists. Three basic features are dynamic storage allocation, integer array names as pointers, and a seven-word head for each array.
The index of dissimilarity can be interpreted as the ratio of the number that must be moved from cells of excess to cells of deficit to achieve even distribution. This interpretation is used to generalize the index in two directions. First, the index is made applicable to more than two groups at a time. Second, an index and a test of significance are made available for explorations of cells of a two-way contingency table. DISSIM is the name of a computer program which provides these calculations for contingency tables.

The basic spirit of structured programming is to write programs that are easy to read and debug. Students who are taught programming should be encouraged to use structured programming principles. Ingredients of structured programming include:
This is a report on computer programming undertaken to preprocess the 1960–1970 U. S. census public use samples to increase their accessibility. This includes wholesale recoding into positive integers from 1 to N, with 0 reserved for “not applicable”, combining household and person records, sorting records into ten 1/10,000 samples, compacting binary codes to fit on a single reel of tape, and the production of a revised set of formatted tapes.
A computerized probability model of family building is described. Called FERMOD, the model is designed to follow the changing distribution of children ever born and birth intervals of a large homogeneous population as it moves through the reproductive period. Use of the model presupposes assumptions about such factors as risks of fetal wastage, lengths of pregnancy, and postdelivery amenorrhea conditional to outcome of pregnancy, length of reproductive period, fecundability, desired family size, preferred birth spacing!, and effectiveness of contraception. Use of FERMOD is illustrated in a limited application to United States fertility. Relations to other models are briefly discussed.
“The factor analyses of four traits rated in different situations reveal at least two different general kinds of situations which affect the rating of traits. These are the ‘verbal’ and the ‘active’ situations. The factor analysis of the over-all rating of 10 traits suggests three general concepts which appear to be useful in the analysis of the behavior of individuals in a situation. These concepts are abilities, interest and motivation, and social adjustment.” (PsycINFO Database Record (c) 2006 APA, all rights reserved)
