| A major task of economics and policy economics is to explain the pattern of government behavior in its interventions in the economy. This paper introduces the use of the Decision Tree methodology to help capture policy making behavior and provide extended insights into the decision making process. Decision Tree is a flexible, non-parametric, data-driven procedure which has been in use since the early 1970's, both as a classification and as a prediction tool; its use in economics has so far been rare, and in modeling regulatory agency behavior in decision-making has been virtually non-existent. Use of this approach not only reveals the significant conditions driving a phenomenon, but also provides a ranking of the conditions - information not readily... |

| Abstract Background: Cocaine- and amphetamine-regulated transcript (CART), discovered initially by via differential display RT-PCR analysis of brains of rats administered cocaine, is expressed mainly in central nervous system or neuronal origin cells, and is involved in a wide range of behaviors, such as regulation of food intake, energy homeostasis, and reproduction. The hens egg-laying rate mainly depends on the developmental status of follicles, expression of CART have not been identified from hen follicles, the regulatory mechanisms of CART biological activities are still unknown. The objective of this study was to characterize the mRNA expression of CART in hen follicular granulosa cells and determine CART peptide localization and regulatory role... |

Agr. 40(2): 351-360. Nothofagus dombeyi grows in a wide variety of sites in Chile (30-47°S), but there is little knowledge about its productive potential. This lack of information hinders decision-making to better guide the production of goods and services from these forests. This study was conducted in central-southern Chile (39°S-41°S), where this species is prominent, especially in secondary forests. The aim of the study was to determine the homogeneous edaphoclimatic zones for secondary forests of N. dombeyi based on the integration of environmental factors.... |
