Why Do Females Live Longer Than Males? - Proceedings ASTIN 2001 - Washington, United States of America

چکیده
In most countries, females live several years longer than males. Many biological and behavioral reasons have been presented in the scientific literature to explain this female advantage. A crosssectional regression study, using 50 explanatory variables and data collected from 169 countries, provides support to the behavioral hypothesis. Four variables, unrelated to biological sex differences, explain over 61% of the variability of the life expectancy differential. One variable (the number of persons per physician) summarizes the degree of economic development of a country. The three other selected variables (the fertility rate, the percentage of Hindus and Buddhists, and Europeans living in the former Soviet Union) are social/cultural/religious variables.

Parenting and survival in anthropoid primates: caretakers live longer.
Most anthropoid primates are slow to develop, their offspring are mostly single births, and the interbirth intervals are long. To maintain a stable population, parents must live long enough to sustain the serial production of a sufficient number of young to replace themselves while allowing for the death of offspring before they can reproduce. However, in many species there is a large different...
متن کاملBootstrap Methodology in Claim Reserving - Proceedings ASTIN 2001 - Washington, United States of America
In this paper, we use the bootstrap technique to obtain prediction errors for different claim reserving methods, namely methods based on the chain ladder technique and on generalised linear models. We discuss several forms of performing the bootstrap and illustrate the different solutions using the data set from Taylor and Ashe (1983) which has already been used by several authors.

متن کاملPaternity and relatedness in wild chimpanzee communities.
The genetic structure of three contiguous wild chimpanzee communities in West Africa was examined to determine the extent to which the community, the mixed-sex social unit of chimpanzees, represents a closed reproductive unit. An analysis of paternity for 41 offspring resulted in 34 cases of paternity assignment to an adult male belonging to the same community. Among the 14 offspring for which ...
متن کاملA nonspecific fatty acid within the bumblebee mating plug prevents females from remating.
The best mating strategy for males differs from that of females, because females gain from mating with several males (polyandry), but males gain from monopolizing the females. As a consequence, males have evolved a variety of methods, such as the transfer of inhibitory substances from their accessory glands, to ensure exclusive paternity of the female's offspring, generally with detrimental eff...
