A uniform weak law of large numbers under π-mixing with application to nonlinear least squares estimation

Abstract  In B ierens (1981) we have derived a uniform weak law of large numbers for stochastically stable processes with respect to a finite-dependent base. In this paper we show that this uniform weak law carries over to stochastically stable processes with respect to a, more general, φ-mixing base. This generalization will be used for relaxing the conditions for weak consistency and asymptotic normality of nonlinear least squares estimators.     

The care and feeding of MBA's

Hiring MBA's represents an investment at a significant risk level, and data on the firm's historical experience with MBA investments should be maintained and evaluated. The characteristics of the MBA which count toward performance should be discovered. The authors suggest several: maturity measures, quantitative orientation, educational specialty, attitude toward work.     

Population policy aspects of the employment of foreigners

The author considers the medium-range and long-term effects of declining fertility in the Federal Republic of Germany, including the consequences for the population, age structure, economy, and social security system. The slight rise in the number of births is attributed to the presence of foreigners, and it is suggested that only a rapid resumption of immigration will assure demographic stability (SUMMARY IN ENG)     

Clinic visit and waiting: patient education and satisfaction

Teaching should be part of every patient's health care. Even though this study did not show that teaching improves patient satisfaction with the clinic visit, it did indicate that subjects who were taught by the nurse were more satisfied with the education received during that visit.$     

Alcohol abuse and liver enzymes (AALE): results of an intercompany study of mortality

Evaluation of applicants for life insurance who have elevations of their liver function tests or an increased probability of alcohol abuse has always been difficult for underwriters. This paper reports the results of an intercompany study in which the pooled mortality experience of a group of insureds with evidence of alcohol abuse, an adverse driving record or elevations of the liver transaminases or gamma-glutamyl transferase is summarized.
