On the relationship between migration and fertility

The relationship between migration and fertility is examined. The author proposes an alternative model to those used previously and applies it to data from the 1973 National Demographic Survey of the Philippines. The model assumes that although the fertility of migrants declines initially because of economic and psychological hardships, it rises subsequently as migrants become settled in their new environment.     

Reexamining Masculinity,Femininity,and Gender Identity Scales

This research compares and contrasts three gender identity instruments, the Bem Sex Role Inventory (BSRI), the Personal Attributes Questionnaire (PAQ), and the Sexual Identity Scale (SIS), that have been used in previous investigations of various aspects of consumer behavior. Specifically, it examines the dimensionality and internal reliability of each scale, inter-scale correlations, and the relationship of each scale to biological sex. Results indicate that the gender identity scales consist of several dimensions beyond those typically interpreted as masculinity and femininity. The femininity factors emerging in the three scales tended to be highly correlated, and females scored higher than males on the femininity factors. However, the three masculinity factors were not correlated with one another, and were not as strongly associated with biological sex—females identified with typically masculine traits just as much as males. The implications of these results for using gender identity in consumer research are discussed, and future research opportunities are explored.     

Health care purchasing alliances--a Michigan multiemployer trust funds' approach

A group of multiemployer trust funds in Michigan has formed a coalition that eventually will offer its members an integrated managed health care program. As the first step toward this goal, the coalition recently implemented a managed pharmaceutical program.     

Economics and the treatment of AIDS: a preliminary assessment

This paper applied cost-effectiveness analysis to the use of drug therapy in the treatment of AIDS. The empirical approach adopted overcame the facts that the samples of patients had varying clinical prognoses, had variable entry dates into the samples and, because AIDS is a terminal disease, had variable exit dates. Holding these variables constant, administration of the drug AZT proved to be a less costly alternative than other existing palliatives for AIDS. The sub-sample of patients treated with AZT had lower hospitalization costs, lower caring costs and sufferers had an increased ability to continue to participate for longer as economically active members of society.     

Greater curvature antral flattening: A radiologic sign of NSAID-related gastropathy

We have occasionally encountered patients on nonsteroidal antiinflammatory drugs (NSAIDs) in whom double contrast barium studies revealed persistent flattening and stiffening of the distal greater curvature of the stomach. We therefore performed a study to determine the frequency of this finding in patients with NSAID-related gastropathy. Twenty-one cases of erosive gastritis, gastric ulcers, and/or gastric scarring associated with a known history of NSAID use were reviewed by two radiologists who made a joint decision regarding the presence or absence of greater curvature antral flattening. This finding was seen radiographically in five of the 21 patients (24%). Four of the five patients with antral flattening had associated erosions or ulcers in the gastric antrum. The remaining patient had antral flattening as an isolated finding. Our experience suggests that flattening of the greater curvature of the distal antrum, particularly if associated with erosive gastritis or gastric ulcers, is a useful radiologic sign of NSAID-related gastropathy.     

A comparison of alternative methods of updating input-output coefficients

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.
