South American transport statistics system (Setas)

A meeting of experts was held in Santiago, Chile on 27 and 28 October 1999 to mark the start of the project for the development of the South American Transport Statistics System (SETAS). The main objective of the meeting was to analyse different elements for the development of a SETAS pilot project. The meeting was attended by representatives of Bolivia, Brazil and Chile, the countries chosen to participate in this early stage of the project's development. Officials from the Latin American Integration Association (LAIA), and from the Statistics and Economic Projections Division and the Transport Unit, Natural Resources and Infrastructure Division of ECLAC also participated. This edition of the FAL Bulletin focuses on this regional effort, listing the specifications and components of the SETAS pilot plan and the results expected from its implementation.

Neostructuralism and heterodox thinking in Latin America and the Caribbean in the early twenty-first century

The thinking that has unilaterally dominated economic science for over five decades has recently come under intensive scrutiny and its validity and conceptual and empirical coherence are the subject of controversy. Thus the limitations of the prevailing paradigm for addressing the failures of free market economies have been laid bare. For Latin America and the Caribbean, these failures are structural in nature, as indeed structuralism proposed in its time. Neostructuralism delves more deeply into the issues addressed in structuralism, aiming to improve positioning in the international economy, boost productive employment creation, reduce structural heterogeneity and improve income distribution, while maintaining financial balances capable of sustaining changes in the sphere of production by means of social and State support. Far from being an insular system of thinking, neostructuralism is an open system that lends itself to dialogue with other philosophies that recognize the limitations of the dominant paradigm and object to its methodological monism. This book offers a fresh look at neostructuralism and heterodox thinking at the start of the twenty-first century. In a context shaped by the impacts of the worst economic and financial crisis since the Great Depression and by paradigmatic changes at the global level, it aims to carve out arenas for discussion between alternative lines of thinking in order to lay the foundations for a socioeconomically inclusive and environmentally sustainable model of development for the region.

Manual responses to visual stimuli: early and late facilitatory effects due to the offset of a peripheral cue

Os tempos de reação manuais e sacádicos (TRMs e TRSs) são reduzidos quando um sinal de aviso precede o aparecimento do alvo. O decréscimo nos TRSs observados depois do desaparecimento do ponto de fixação tem sido chamado de efeito de intervalo. Teorias diferentes foram propostas para explicá-lo. De acordo com alguns autores, o desaparecimento também permite ao sistema sacádico gerar uma população separada de TRSs, as sacádicas expressas. No entanto, não há concordância sobre a influência do desaparecimento de um estímulo periférico no TRM. Em dois experimentos, testou-se os efeitos de um desaparecimento visual periférico empregado como um sinal preparatório para os TRMs a um alvo, após intervalos variáveis. Encontrou-se uma redução no TRM para intervalos curtos (200-300 ms) e longos (1300-2000 ms) após o desaparecimento periférico. A distribuição dos TRMs deslocou-se para latências curtas, formando por vezes populações separadas. Visto que os TRMs obtidos em intervalos longos foram afetados pela introdução de sessões capciosas, enquanto que os TRMs em intervalos curtos não o foram, propõe-se que dois mecanismos diferentes estão envolvidos no decréscimo dos TRMs: alerta e expectativa temporal. Nossos dados sustentam a hipótese de que o componente temporal envolvido com os estágios preparatórios das respostas motoras podem ser compartilhados pelos movimentos sacádicos e pelas respostas de apertar botões, permitindo a redução das latências motoras após o desaparecimento visual, dentro do paradigma do intervalo. Nossos dados corroboram o modelo de três componentes do efeito de intervalo. Em nosso ponto de vista, a questão da existência ou não do efeito de intervalo para respostas manuais é essencialmente conceitual.

Development of a CAD system for automatic classification of microcalcifications based on FPGA

This paper presents a Computer Aided Diagnosis (CAD) system that automatically classifies microcalcifications detected on digital mammograms into one of the five types proposed by Michele Le Gal, a classification scheme that allows radiologists to determine whether a breast tumor is malignant or not without the need for surgeries. The developed system uses a combination of wavelets and Artificial Neural Networks (ANN) and is executed on an Altera DE2-115 Development Kit, a kit containing a Field-Programmable Gate Array (FPGA) that allows the system to be smaller, cheaper and more energy efficient. Results have shown that the system was able to correctly classify 96.67% of test samples, which can be used as a second opinion by radiologists in breast cancer early diagnosis. (C) 2013 The Authors.

Early influence of auditory stimuli on upper-limb movements in young human infants: an overview

Given that the auditory system is rather well developed at the end of the third trimester of pregnancy, it is likely that couplings between acoustics and motor activity can be integrated as early as at the beginning of postnatal life. The aim of the present mini-review was to summarize and discuss studies on early auditory-motor integration, focusing particularly on upper-limb movements (one of the most crucial means to interact with the environment) in association with auditory stimuli, to develop further understanding of their significance with regard to early infant development. Many studies have investigated the relationship between various infant behaviors (e.g., sucking, visual fixation, head turning) and auditory stimuli, and established that human infants can be observed displaying couplings between action and environmental sensory stimulation already from just after birth, clearly indicating a propensity for intentional behavior. Surprisingly few studies, however, have investigated the associations between upper-limb movements and different auditory stimuli in newborns and young infants, infants born at risk for developmental disorders/delays in particular. Findings from studies of early auditory-motor interaction support that the developing integration of sensory and motor systems is a fundamental part of the process guiding the development of goal-directed action in infancy, of great importance for continued motor, perceptual, and cognitive development. At-risk infants (e.g., those born preterm) may display increasing central auditory processing disorders, negatively affecting early sensorymotor integration, and resulting in long-term consequences on gesturing, language development, and social communication. Consequently, there is a need for more studies on such implications.
