A two-process theory of human information processing is proposed and applied to detection, search, and attention phenomena. Automatic processing is activa-tion of a learned sequence of elements in long-term memory that is initiated by appropriate inputs and then proceeds automatically

We estimate the relative influence of trade versus technology on wages in a "large country" setting, where technological change affects product prices. Trade is measured by the foreign outsourcing of intermediate inputs, while technological change is measured by expenditures on high

cash flows. Because of the severe market reaction to missing an earnings target, we find that firms are willing to sacrifice economic value in order to meet a short-run earnings target. The preference for smooth earnings is so strong that 78 % of the surveyed executives would give up economic value

environments. In classical planning work, problems were posed with unique initial and final world states; in my approach a problem specifies only a goal condition. The planner is thus unable to commit to any specific future course of events but must specify appropriate reactions for anticipated situations

to be marginally related. Of all the variables considered, the strongest evidence is for the relative price of investment, primary school enrollment and the initial level of real GDP per capita.

aversion slightly, but its effect is not statistically significant. Key words: India, psychological experiments, risk aversion, semi-arid tropics. The research reported here was carried out in the semi-arid, tropical areas of India, charac-terized by high climatic risk for agriculture. It was initiated

in vitro, and mathematical models of the constituent reactions pre-dict the rate of motion. Signaling pathways converging on WASp/Scar proteins regulate the activity of Arp2/3 complex, which mediates the initiation of new filaments as branches on preexisting filaments. After a brief spurt of growth

of the translations and rotations made by players of this video game are best understood as actions that use the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to change the world in order to simplify the problem-solving task. Thus, we distinguish

Evidence presented here is consistent with a failure of stock prices to reflect fully the implications of current earnings for future earnings. Specifically, the three-day price reactions to announcements of earnings for quarters t + 1 through I + 4 are predictable, based on earnings of quarter r

reaction-diffusion systems in which one system lays down an initial pattern and then one or more later systems refine the pattern. Examples of patterns generated by such a cascade process include the clusters of spots on leopards known as rosettes and the web-like patterns found on giraffes. In addition
