Computing the level and distribution of gains from fertility reduction.

"This paper describes and illustrates new procedures for measuring monetary gains from fertility reduction that can be applied to macromodels of population and development. A previously developed method for calculating the total monetary gain from averted births is reviewed. A new technique for distributing gains between birth-averting households and society at large is explained....A technique for evaluating alternative fertility reduction programs is described. Each of the methods is applied to a macromodel estimated from a cross section of countries."

Multiple myeloma with an IgD kappa monoclonal protein.

The case of a female patient with multiple myeloma in whom the circulating monoclonal protein was IgD with kappa light chains is presented. The case is extremely unusual and serves to emphasize how little is known about the function, metabolism, and regulation of immunoglobulin D.

Sex selection with biased technologies and its effect on the population sex ratio.

Current biomedical research on sex selection techniques may soon offer couples the opportunity to choose the sex of their children with greater certainty. A technique planned for marketing by mid-1978 can increase the probability of bearing a son to as much as 0.90. However, couples who wish to improve their chances of bearing a daughter have no such opportunity. The purpose of this paper is two-fold. First, a decision-making model is provided which describes how couples should choose among alternative sex-selection methods so as to maximize the probability of bearing their desired number of sons and daughters. Second, the effect of the widespread use of sex-selection techniques on the population sex ratio is explored. It is shown that even if populations have unbiased sex preferences, or sex preferences biased towards daughters, the use of biased sex-selection technologies may result in very high population sex ratios.

Food safety education: what should we be teaching to consumers?

Food safety education is most effective when messages are targeted toward changing behaviors most likely to result in foodborne illness. The five major control factors for pathogens are personal hygiene, adequate cooking, avoiding cross-contamination, keeping food at safe temperatures, and avoiding foods from unsafe sources. Pathogens associated with poor personal hygiene have the highest incidence and costs. Inadequate cooking and cross-contamination have lower incidence. Keeping food at safe temperatures and unsafe food sources have the lowest incidence, although costs per case are sometimes very high. We recommend that consumer food safety educators primarily focus on hand washing, adequate cooking, and avoiding cross-contamination. Secondary messages should focus on keeping food at safe temperatures and avoiding food from an unsafe source. Evaluation tools are needed to evaluate self-reported behavior changes. The evaluation questions must focus on salient behaviors that are most likely to result in foodborne illnesses and must withstand rigorous standards of reliability and validity.
