Background: The Human Development Index (HDI) is a composite statistic of life expectancy, education, and income per capita indicators, which apart from measuring the socio-economic development of countries can predict health outcomes. The current study aimed at determination of the effects of HDI individual components on infant and child mortality. Materials and Methods: At a cross- sectional ...

Ecological conditions are expected to have an important influence on individuals' investment in cooperative care. However, the nature of their effects is unclear: both favorable and unfavorable conditions have been found to promote helping behavior. Recent studies provide a possible explanation for these conflicting results by suggesting that increased ecological variability, rather than change...

methods to illuminate the night. In pre-industrial times, artificial light was generated by burning various materials, including wood, oil, and even dried fish. While these methods of lighting certainly influenced animal behavior and ecology locally, such effects were limited. The relatively recent invention and rapid proliferation of electric lights, however, have transformed the nighttime env...

Located in the central Chinese Loess Plateau, the Jinghe River is one of the major tributaries of the Yellow River, and the river basin it inhabits is characterized by a continental climate. Considering that land degradation has been the main ecological problem in the Jinghe River Basin, there is an urgent need to scientifically explore the land degradation mechanism in order to restore natural...

A representational approach to ecological psychology is presented. This paper identifies a computational-level commonality in ecological psychology research related to passability of apertures. It is argued that a cognitive mechanism capable of comparing the geometric properties of an environment and the geometric properties of the agent can be used to support judgments for action in space.

An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one’s successfully supported action in the environment, this...

Increasingly on a worldwide scale, legislation has been adopted to determine the ecological integrity of surface waters including streams, rivers, lakes, estuaries and coastal waters. An integral part of determining ecological integrity is the measurement of biological integrity, typically emphasizing analyses of plankton, benthos, macroalgae and fish. In the development of protocols for evalua...
