Animal research has played a central role in psychology, yet its clinical value and ethical propriety have recently come under attack. In an effort to assess current thinking on this controversial subject, a mail survey was sent to 5,000 randomly selected members of the American Psychological Association. Responses were received from 3,982 individuals, and the results showed (a) majority suppor...

Real time and markerless motion capture is an active research area, due to applications in human-computer interactions, for example. A large part of the existing markerless motion capture methods require an initialization step, consisting in finding the initial position of the different limbs of the subject. In this paper, we propose a new method for interactive time initialization step, only b...

The communication systems of nonhuman animals are reviewed, together with a discussion of their relevance for the evolution of human language. The teaching of language to nonhumans, as well as signs of mind and consciousness outside our species, are considered as possible bridges between us and the rest of the animal kingdom.

Gelatinous zooplankton are the least understood of all planktonic animal groups. This is partly due to their fragility, which typically precludes the capture of intact specimens with nets or trawls. Specialized tools and techniques have been developed that allow researchers and aquarists to collect intact gelatinous animals at sea and to maintain many of these alive in the laboratory. This pape...

In this paper, the role of the human being toe is investigated. The change of the sole pressure distribution using a sole pressure distribution measurement system and that of the toe pressure using a toe pressure measurement system at walk by the existence of a toe are investigated. In order to investigate the change of the whole walking, the affection of a walk posture using a 3D motion captur...

In this paper, we present Bayesian analysis of capture-recapture models for a closed population which allows for heterogeneity of capture probabilities between animals and bait/trap effects. We utilize a flexible discrete mixture model to account for the heterogeneity and behavioral effects. In addition we present a solid model selection criterion. Through illustrations with a real-world motiva...

Social behavior of animals can offer solution models for missions involving a large number of heterogeneous vehicles, such as light combat ships, unmanned aerial vehicles, and unmanned underwater vehicles. We draw inspiration from the foraging techniques of bottlenose dolphins to address the problem of heterogeneous multi-agent herding. We produce a hybrid automaton model of the entire foraging...

Capture-recapture models were developed to estimate survival using data arising from marking and monitoring wild animals over time. Variation in survival may be explained by incorporating relevant covariates. We propose nonparametric and semiparametric regression methods for estimating survival in capture-recapture models. A fully Bayesian approach using Markov chain Monte Carlo simulations was...
