Resumo A formação da mão-de-obra no Brasil no decorrer da Primeira República (1890-1930) se fez de forma acelerada e em dois campos simultaneamente no rural e no urbano. No rural, pelo aquecimento da demanda internacional pelo café brasileiro, e, no urbano, pelo início da industrialização, principalmente, nas cidades do Rio de Janeiro e de São Paulo. Tanto nas atividades agrícolas, como nas industriais, a presença e a participação do imigrante estrangeiro foram hegemônicas e decisivas. É preciso considerar que a abolição da escravatura havia ocorrido em 1888, criando um esvaziamento do mercado de trabalho no Brasil. Palavras chave: imigração estrangeira; cafeicultura, industrialização; sindicalismo; relações de trabalho.Resumo Labor formation in Brazil took an accelerated rhythmus during the First Republic (1890-1930) in two fields simultaneously: rural and urban. In the rural sector it was due to an increase in international demand for Brazilian coffee. In the urban areas, meanwhile, the beginning of industrialization, specially in Rio de Janeiro and São Paulo, was the main cause. Not only in the agricultural activities. but also in the industries, the presence and participation of foreign immigrants were decisive. The abolition os slavery in 1888 must be considered as part of this context, as it changed the labour market. Keywords: foreign immigration; coffee growing; industrialization; trade unionism; work relations.

Often a pair of quantum systems may be represented mathematically (by a vector) in a way each system alone cannot: the mathematical representation of the pair is said to be non-separable: Schrödinger called this feature of quantum theory entanglement. It would reflect a physical relation between a pair of systems only if a system’s mathematical representation were to describe its physical condition. Einstein and colleagues used an entangled state to argue that its quantum state does not completely describe the physical condition of a system to which it is assigned. A single physical system may be assigned a non-separable quantum state, as may a large number of systems, including electrons, photons, and ions. The GHZ state is an example of an entangled polarization state that may be assigned to three photons.
