| The present article is the adapted version of an electronic symposium organized by the Brazilian Society of Neuroscience and Behavior (SBNeC) which took place on June 14, 2000. The text is divided into three sections: I. The main issues, II. Chronodrugs, and III. Methods. The first section is dedicated to the perspectives of chronobiology for the next decade, with opinions about the trends of future research being emitted and discussed. The second section deals mostly with drugs acting or potentially acting on the organism's timing systems. In the third section there are considerations about relevant methodological issues concerning data analysis. |

| In this work the management effectiveness of a Cuban MPA is assessed using an interdisciplinary approach. A series of three hypotheses are tested to determine how effective the Punta Frances Marine Protected Area (PFMPA) has been in meeting the multiple objectives of conserving biological diversity and ecological integrity, while allowing for the development of economic opportunities for tourism, and satisfying the needs of local and distant human populations. A new typology of benefits derived from MPAs was produced to provide managers with a practical tool that enable them to: 1) identify the benefits at the early stages of MPA creation, 2) state MPA objectives in a clear and measurable way, 3) assess the effectiveness of their MPA in meeting... |

| Daily growth increments (DGI) density - otolith radius relationship according to the von Bertanlanffy's growth model: application to Lutjanus sebae (Cuvier, 1828) in Seychelles. Often, age determination of fishes is conducted from several parts (scales and otoliths for teleost fishes, vertebrae, spine, opercular bones, ...) displaying seasonal marks (annuli) associated with growth checks, which can be used for the estimation of individual age. Since Panella's (1971, 1974) discovery of the daily growth increments (DGI) in the teleost otoliths, age determination with DGI method has been used more and more on larval stages of both temperate and tropical species and juvenile and adult individuals of, principally, snapper and grouper species. The age study of... |

| The age study of fishes using daily growth increments DGI observations is made from: 1- either the exhaustive determination of increments, 2- or the calculation of daily growth increments density for different otolith zones between the nucleus and the margin edge of otolith, the width of increments being presumed constant for each zone. To apply the first method, increments may be readable individually from the nucleus to the margin edge of otolith. This is a very time consuming operation. It can cause miscalculation of increments and errors of the age estimation. The second method, called "DGI density method" is based on the decrease of the increment width in relation to the slowing down of the growth phenomena. The more used approach according to this... |

| There is a continuously growing literature on the agricultural transformation in Central and Eastern European countries (see some surveys in Brooks and Nash 2002; Rozelle and Swinnen 2004). The research has focused on various aspects of transition, including land reform, farm restructuring, price and trade liberalisation, but even though Farm Accountancy Data Network (FADN) data are now available for some years, there are only a few studies (e.g. Bakucs et al. 2010, Fogarasi and Latruffe, 2007, Baráth et al., 2009) focusing on Hungarian farm performance. The objective of this paper is to shed light on some methodological issues that are needed to study Hungarian farm performance. Here we consider one aspect of farm performance, namely technical efficiency.... |

| This paper explains the development and implementation of a methodology for assessing the economic impacts of large-scale environmental regulations. The development process began with a literature review surveying channels through which environmental regulations might influence economic performance. Avenues deemed suitable were incorporated into a computable general equilibrium (CGE) model of the California economy. This model is based on the California Department of Finance's Dynamic Revenue Analysis Model (DRAM). Modifications to DRAM for the current project include a revised sectoring scheme that features industries of particular regulatory interest, revamped data matrices that accommodate this new sectoring scheme, a new air pollution module,... |
