Division of labor between M and P visual pathways: different visual pathways minimize joint entropy differently

Visual perception and action are strongly linked with parallel processing channels connecting the retina, the lateral geniculate nucleus, and the input layers of the primary visual cortex. Achromatic vision is provided by at least two of such channels formed by the M and P neurons. These cell pathways are similarly organized in primates having different lifestyles, including species that are diurnal, nocturnal, and which exhibit a variety of color vision phenotypes. We describe the M and P cell properties by 3D Gábor functions and their 3D Fourier transform. The M and P cells occupy different loci in the Gábor information diagram or Fourier Space. This separation allows the M and P pathways to transmit visual signals with distinct 6D joint entropy for space, spatial frequency, time, and temporal frequency. By combining the M and P impacts on the cortical neurons beyond V1 input layers, the cortical pathways are able to process aspects of visual stimuli with a better precision than it would be possible using the M or P pathway alone. This performance fulfils the requirements of different behavioral tasks.

Educational and professional background and success in the labor market: the case of Portuguese immigrants in the Netherlands

The aim of this paper is to describe the relationship between educational and professional occupation trajectories of Portuguese immigrants in The Netherlands. To this end, the sample used comprises Portuguese immigrants that arrived in The Netherlands in two periods which represent the highest influx of immigrants: around the years 1966 and 2002. The analysis of the data shows a strong relationship between the level of professional education and the level of professional occupation. Furthermore, some exceptions to the generalizations found show that in service training may lead to an improvement of the possibilities to ascend regarding the level of professional occupation.

Filoctetes de Sófocles: o espaço e o labor humano

This article analyses the transformations of spatial references in Sophocles’Philoctetes. As we can see, instead of being cristalized in formulas and conventions, Ancient Greek Theater has renewed itself constantly, by experiencing different ways to correlate audience and events on stage.

The Young Mother and the Labor Market

Introduction - The Centro de Orientacao ao Adolescente of Campinas (Southeastern Brazil) maintains a program to qualify economically disadvantaged adolescent students aged 15 to 18 years to enter the labor market. Objective - To understand life projects of teenagers who became mothers while participating in the program, in the period from 2003 to 2008, aiming to find the place of professional life in their life trajectory before and after motherhood. Method - Eight young mothers were interviewed, and a qualitative methodology was applied to the analysis of the interviews. Results - The trajectories of study and work were discontinued or adapted due to motherhood. Four young mothers completed high school and none had entered university. Three did not return to work and the rest had diverse work experiences. The reported difficulties to enter the labor market were: inadequate instruments to support the children's care, low income, lack of work experience, presence of small children and little educational background. Final Considerations - Teenage motherhood did not indicate the exclusion of educational or work projects but indicated adjustments and the need for a family and social support network. It was noted the need for public policies targeted at the inclusion of youths in the labor market and at support services such as nurseries. Also, the need for a change in gender relations was demonstrated, with greater equality of rights as a precondition for the inclusion of women, especially those who are mothers, in the labor market.

Migrant labor and wear-out in manual sugarcane harvesting in Sao Paulo, Brazil

The scope of this paper is to describe the work of manual sugarcane harvesters, assessing the nutritional behavior and body composition between the beginning and the end of the harvest. A descriptive longitudinal study was made of harvesters in Piracicaba, Sao Paulo, Brazil, who answered a socio-demographic questionnaire and authorized measurement of Body Mass Index, Body Fat Percentage and Arm Muscle Circumference at three stages. Creatine kinase on the skeletal isoform, C-reactive protein and plasma urea were measured at the end of the harvest. Thirty male migrant harvesters with ages ranging from 18 to 44 from the Northeast (Ceara) were assessed over a nine-month period. The workers suffered significant body fat and weight loss in the first half of the harvest. Eighteen workers had abnormal levels of creatine kinase and four - out of 24 who had donated blood - had altered urea levels. Sugarcane harvesting work causes weight and body fat loss and gains in the lean body mass index, which suffers wear-out when working on consecutive harvests. It can also cause changes in biochemical markers of chronic systemic inflammation. Further studies will make it possible to comprehend the relationships between stress, wear-out, labor longevity and health in sugarcane harvesting.

Children and teenagers working in artistic labor: Brazilian situation and international examples

This descriptive study about children and adolescents artistic labor verifies the applicable legislation, in Brazil, regarding the participation of children and adolescents in the entertainment industry and in advertising campaigns, as well as the judicial processes about the theme known by the Brazilian Superior Court of Justice up to October, 2010. The results permit to conclude that, due to the lack of specific regulation and general rule of child labor prohibition, the restrictions that tend to protect the health and security of children and adolescents that act in the artistic niche (television, advertising, fashion, movies etc.) have been, in Brazil, at subjective criteria of the judges and, in many cases, in the hands of producers themselves. Brief considerations on how other countries regulate the theme are also presented (the USA, Portugal and Argentina).

O edifício da FAUUSP e os materiais do brutalismo

O trabalho analisa a história da produção do edifício da Faculdade de Arquitetura e Urbanismo da Universidade de São Paulo, projetado por João Batista Vilanova Artigas (1915-1985) em 1961 e concluído em 1969. Mais especificamente, o artigo se volta aos materiais do edifício, oferecendo insumos para uma discussão sobre o papel do chamado “brutalismo paulista” na década de 1960. O edifício da FAUUSP, como se sabe, é um marco na arquitetura moderna brasileira. Seu caráter paradigmático consiste na síntese das posições programáticas de Artigas, tanto em relação ao ensino de arquitetura como em relação à poética moderna, que ultrapassa o limite autoral e constitui uma escola. São características dessa escola – por vezes chamada de “paulista”, “brutalista” ou “artiguista” – alguns princípios como a continuidade espacial, o elogio das formas estruturais, a verdade dos materiais e o desenvolvimento das forças produtivas através da superação tecnológica. Esses princípios respondiam a algumas das questões mais urgentes da arquitetura moderna brasileira naquele período, deslocando a nova monumentalidade para uma dimensão construtiva. A nova poética, claramente exposta no projeto da FAUUSP, coincide com o surgimento de uma estética que atribuiu um novo valor político e crítico à produção. Passam a ser frequentes, por exemplo, interpretações do concreto armado brasileiro como síntese do subdesenvolvimento, por suas marcas de feitura artesanal e seus recordes tecnológicos. O objetivo deste artigo é contribuir com esse debate caracterizando em detalhe a produção do edifício em seus materiais: o concreto armado, a esquadria, os materiais de acabamento e os componentes industriais. O exame de aspectos históricos da produção do edifício, recolhidos em documentos originais e depoimentos, permite verificarmos de que modo a poética arquitetônica participa das decisões da obra e qual o seu impacto na economia do edifício e em sua forma de produção. Aprendemos, por exemplo, que o concreto armado apresenta manifestações visuais distintas e independentes de seu modo de produção (que foram pelo menos três: moldado in loco, protendido, e com agregados leves, sem função estrutural); que a empena da fachada exigiu uma fundação própria para seu cimbramento; que a modulação dos caixilhos não correspondia à modulação da estrutura; que a resina epóxi foi usada de modo pioneiro e experimental; que as fôrmas foram produzidas por um hábil carpinteiro português, mas as relações de trabalho eram precárias; que a contratação do projeto básico previa o detalhamento durante a obra pelo Escritório Técnico do Fundo para a Construção da Cidade Universitária. Essa noção ampla de material, entendida como a matéria mais o trabalho social que a define historicamente, nos permite tratar, simultaneamente, de aspectos técnicos, econômicos e artísticos da obra e assim compreender com maior exatidão dos termos do debate acerca da produção na arquitetura “brutalista” e seu papel político.
