•Male olive baboons invest in both mating effort and parenting effort•Investment are negatively correlated•Parenting has negative, but uncertain, effects on paternity success•Males seem to trade off Reproductive strategies defined by expenditures of time energy devoted effort, which increases opportunities, enhances the survival offspring. We examine tradeoffs between male baboons, Papio anubis...

conclusions postural stress among female machinists can increase the level of si to fairly risky and dangerous. also, changes in rating hand/wrist qec scores with hand/wrist si score were proportional in the studied samples. the si can increase under the influence of noise above 85 db, although it is not statistically significant. results there was no significant difference between work experie...

This paper develops a model of career concerns. The worker’s skill is revealed through output, wage is based on expected output, and so on assessed ability. Specifically, effort increases the probability that a skilled worker achieves a one-time breakthrough. Effort levels at different times are strategic substitutes. Equilibrium effort (and, if marginal cost is convex, wage) is single-peaked w...

We propose a prediction-based best-effort real-time service to support distributed, interactive applications in shared, unreserved computing environments. These applications have timing requirements, but can continue to function when deadlines are missed. In addition, they expose two kinds of adaptability: tasks can be run on any host, and their resource demands can be adjusted based on user-pe...

This paper presents a game theoretic approach to causal discovery. The problem of causal discovery is framed as a game of the Scientist against Nature, in which Nature attempts to hide its secrets for as long as possible, and the Scientist makes her best effort at discovery while minimizing cost. This approach provides a very general framework for the assessment of different search procedures a...
