Subjects were asked to discriminate scenes after very brief exposures (37-69 ms). Their performance was always above chance and increased with exposure duration, confirming that subjects can get the gist of a scene with one fixation. We propose that a simple texture analysis of the image can provide a useful cue towards rapid scene identification. Our model learns texture features across scene ...

Game theory is commonly used to study social behavior in cooperative or competitive situations. One socioeconomic game, Stag Hunt, involves the trade-off between social and individual benefit by offering the option to hunt a low-payoff hare alone or a high-payoff stag cooperatively. Stag Hunt encourages the creation of social contracts as a result of the payoff matrix, which favors cooperation....

Subjects were asked to identify scenes after very brief exposures (<70 ms). Their performance was always above chance and improved with exposure duration, confirming that subjects can get the gist of a scene with one fixation. We propose that a simple texture analysis of the image can provide a useful cue towards rapid scene identification. Our model learns texture features across scene categor...

1. There is growing concern about the evolutionary consequences of human harvesting on phenotypic trait quality in wild populations. Undesirable consequences are especially likely with trophy hunting because of its strong bias for specific phenotypic trait values, such as large antlers in cervids and horns in bovids. Selective hunting can cause a decline in a trophy trait over time if it is her...

The literature about portals or gateways exists in huge volume. However, only a limited number of articles have addressed the topic of knowledge portals applying various concepts of arrangement to organizing the information on the portals. Likewise, not many authors have written about knowledge portals. So, this study helps to understand one such knowledge portal and its features, coverage of s...

Carol Gilligan bas described justice and caring as two distinct moral frameworks or orientations to ethical concerns. (Gilligan 1982) The justice framework is characterized by abstraction, the application of general rules ofconduct, an emphasis on restraining aggression, and a concern for consistency and the fair resolution of conflicting claims and interests. The caring framework, on the other...

To analyze complex scenes efficiently, the human visual system performs perceptual groupings based on various features (e.g., color and motion) of the visual elements in a scene. Although previous studies demonstrated that such groupings can be based on a single feature (e.g., either color or motion information), here we show that the visual system also performs scene analyses based on a combin...

LED lighting has been widely used in various scenes, but there are few studies on the impact of visual comfort sustained attention tasks. This paper aims to explore influence correlated color temperature (CCT) and illuminance level parameters human comfort. We selected 46 healthy college students (23 male 23 female). The ages ranged from 22 26 years old (average age was 24.2 years). Electroence...

The impact of hunting (selective harvest, trophy hunting) on the demography of mammals is well documented. However, despite continual year-round hunting of bison in some populations, little is known about how the behavior of survivors may be altered. Therefore, in this initial study, we used focal-animal observations in adjacent populations of continually hunted and protected Plains bison (Biso...
