THE EXPANDED SEA SHORE ROTATION MODEL
October 1, 1979
This guide describes a dynamic model which simulates personnel flows in a Navy detailing community. Using historical accessions, continuation rates and promotion probabilities, the model projects an initial inventory to future periods. In each projection period the historical data can be updated to reflect posible changes. Sea/shore rotation patterns can be altered to produce a desired personnel distribution between sea, shore and neutral duty. All computer programs are listed, and some flow charts are provided.

AGGREGATE SEA/SHORE ROTATION MODEL (MOSES)
August 1, 1979
This guide describes a model of the relations between lengths of sea and shore tours, continuation behavior of personnel, and the numbers of first-term and career personnel at sea and ashore. Equations are developed to represent sea/shore rotation systems in which the number of persons in each of these four groups remains the same. This mathematical representation (developed further in CNA Professional Paper 256) was programmed for the computer, and the use and operations of the computer routine, MOSES, are treated here. Listing and flowcharts of the main routine and subroutines are included.

CALCULATING SAMPLE SIZE REQUIREMENTS FOR MILITARY UNIT INSPECTIONS
July 1, 1979
Computer programs for calculating sample size requirements are presented and illustrated. Given the desired significance level and the desired probability that the sample will achieve that level, sample size requirements are calculated for determining that a unit rating: exceeds a criterion on level (with replacement); is less than a criterion level (with replacement); is between two criterion levels (with replacement); exceeds a criterion level (without replacement). The last calculation is done exactly (with the hypergeometric distribution) and also with a normal approximation. In all cases, the required sample size is calculated as a function of the true unit rating.

FORECASTING OUTCOMES OF MULTILATERAL NEGOTIATIONS, COMPUTER PROGRAMS, VOLUME I, GUIDE FOR USERS
December 1, 1978
The present research contribution is a companion publication to CNA Research Contribution 291, which describes the methodology developed and used by the Law of the Sea Study to forecast the outcomes of multilateral negotiations on issues in law of the sea. All of the mathematical models and most of the techniques were programmed for the computer, and it is this system of computer programs that is treated in this research contribution. Volume I directs the prospective user in their execution. Volume II describes their logic and dimensioned variables for the programmer and specifies the changes that must be made throughout the system when any program is changed.

USERS GUIDE TO THE REPORT GENERATOR FOR THE NAVY RESOURCE MODEL
December 1, 1978
The Report Generator is a highly generalized information-extracting and report-formatting computer routine. Through a sophisticated command language and system of dictionaries, it can report out information in countless formats and degrees of detail. The description of the Report Generator in this users' guide is for the dictionaries and data files used in the Navy Resource Model (NARM), at CNA. However, it is possible for the reader to apply the Report Generator to his own management information system by creating his own dictionaries for his own data tapes. How to create dictionaries is described in this guide.

ARIZONA EMPLOYMENT AND UNEMPLOYMENT DATA CODE BOOK
September 1, 1978
The Arizona Employment and Unemployment Data Code Book describes a public use data set developed by PRI from Arizona Unemployment Insurance (UI) administration records and Social Security Administration's Longitudinal Employer-Employee Data (LEED). The UI data is a 20 percent sample drawn from the Arizona Continuous Wage and Benefit History (CBWH) sample. This data base contains detailed longitudinal histories of both the employment and unemployment experience of workers who claimed UI benefits in Arizona between 1963 and 1971. In total, about 40,000 workers are in the file. Employment information includes earnings and principal industry for each year. Unemployment information includes the data and amount of each UI payment, and the date of all administrative actions, such as disqualifications. Age, race, and sex are included as well.

PENNSYLVANIA CONTINUOUS WAGE AND BENEFIT HISTORY CODEBOOK
September 1, 1978
The Pennsylvania Continuous Wage and Benefit History (PA-CWBH) Code Book describes a public use data set developed by PRI from Pennsylvania Unemployment Insurance (UI) administration records. These data cover 4,000 claimants (0.6 percent of the covered population). Information about claims activity, such as the number and amount of UI payments, in 1966, 1967, and 1968 and information about employment, such as annual earnings and principal industry in 1967, 1968, 1969 and 1970, are included in the data.

COSTS OF OWNING, BORROWING AND DISPOSING OF PERIODICAL PUBLICATIONS
December 1, 1977
A library or information center satisfies user needs for a periodical by either maintaining the publication in its own collection or borrowing it from other libraries. At low levels of use, borrowing is the less costly alternative, while at high levels of use owning is the less costly alternative. At an intermediate level of use, called the crossover point, owning and borrowing are equally costly. Crossover points have been estimated as a function of subscription and borrowing costs using cost data from three research libraries and usage characteristics representing collections in either science and technology or humanities and social sciences. These results were estimated by means of a cost model written in APL which can be made available upon request.

A METHOD TO CORRECT CORRELATION COEFFICIENTS FOR THE EFFECTS OF MULTIPLE CURTAILMENT
November 1, 1977
This report examines a general method to estimate the correlation of variables in a large, diverse population from a smaller, selected population in which the ranges of the variables have been restricted. All correlation coefficients are corrected simultaneously, so that an entire correlation matrix can be corrected. Alternate methods are compared. The effectiveness of the method is tested, and an example is given.
