Una mirada al desarrollo infantil en América Latina y el Caribe desde la teoría y el pensamiento sistémico

Este documento investiga las siguientes preguntas relacionadas con las políticas de desarrollo infantil en América Latina y el Caribe: ¿Cuáles son los principales marcos institucionales y legales que determinan la cantidad, naturaleza y prestación de servicios de desarrollo infantil? ¿Qué vínculos y mecanismos de coordinación existen entre las políticas, programas y servicios de desarrollo infantil? ¿Cuáles son los principales desafíos que limitan la capacidad del sistema de desarrollo infantil de los países para producir resultados sistémicos de equidad, calidad y sostenibilidad? Aplicando en el análisis la teoría y el pensamiento sistémico, el documento presenta los resultados de un estudio comparativo en cinco países de la región: Brasil, Chile, Colombia, Guatemala y Trinidad y Tobago

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Qualidade na educação infantil: revisão de um estudo brasileiro e recomendações.

A autora comenta evidências obtidas por pesquisa de avaliação da educação infantil no Brasil, relacionando-as ao debate sobre a qualidade dos serviços educacionais oferecidos às crianças pequenas em âmbito internacional. Refere-se a dados de inúmeros estudos realizados no exterior, os quais indicam que a boa qualidade dos programas de educação infantil impacta o desenvolvimento das crianças a longo prazo. Sugere que, para alcançar maiores níveis de qualidade, é necessário pensar a educação como um sistema constituído de duas partes principais: os programas de educação infantil e a infraestrutura para mantê-los

for greater excellence, coherence, and equity in early childhood education. The history of American early education is one of changing roles and goals. From the privately funded Infant Schools for indigent families in the earliest days of the republic, to the federal government's foray into early childhood with Depression-era nursery schools, to more recent investments in Head Start, federal early education policies can best be understood as a series of 572 PHI DELTA KAPPAN Photo: JIunlimited/Comstock T he federal government's role in early education has a long and contentious history. While the nature and amount of federal engagement has shifted in response to changing social, political, and economic needs, the lack of long-term planning or coordination has yielded an array of programs, dispersed across federal agencies and legislative committees, which begs ### Congress, we've got ideas for you. Invest in Early Childhood Education We need expanded federal leadership in early education to develop an excellent, coherent, and equitable system. The authors recommend 13 ways for the government to develop a universal and sustained approach to early childhood education
