(CACCIAMALI, 1983) In this vision, the modern-traditional dichotomy is kept. Thus, leaving of the same one conceptualization defended for the study in the Kenya, is understood that the informal sector groups all the activities low-level of productivity, beyond englobar diligent independent (done exception to the liberal professionals) and companies very small or not organized. (CACCIAMALI, 1983) the characterization of the informal sector Latin American for the PREALC if shows ampler of what the attempt of the previous study in the Kenya. In synthesis, we have that: (i) formed by a set of activities little capitalized, structuralized on the basis of very small units, low-level technological and scarce or null formal organization productive; (II) the division between proprietors of the capital and the work does not predominate; (III) the wage is not the form most usual to remunerate the work, although the production to be come back toward the market; (IV) in general access is had the stratus of competitive markets or to that they constitute the base of the pyramid of offers of an intent oligoplica structure; (v) is not capable of to determine price (atomizaton of offers), therefore, they do not perceive extraordinary profits. (CACCIAMALI, 1983) Although the sector if not to expand of permanent form, it is not subject to extinguishing.

It is perceived in this point, that the two initial theoretical chains if show divergent. In this last one, one defends now that these activities will be become enlarged, or not, face to the rhythm of expansion of the demand, of the minimum scale of operations for diverse sizes of plant, of the economies of scale and factors politicians. Therefore, the informal activities can be lucrative in short term, but in the long stated period, they tend to lose participation in the market. (CACCIAMALI, 1983) the third theoretical chain, of authorship of Pablo Renato Souza, known as Subordinated Boarding or Theory of the Subordination, believes that a organic relation exists, of complementaridade and subordination of the informal sector before the formal sector of the economy.

Over time fossil fuels began to be challenged by their potential adverse effects, particularly nuclear. More encompassing in a single package, ductile other additions to the technology, the “American way of life”, it was setting aside a smooth, either gradually, all the existing culture to solve the daily life of ordinary people. The preceding paragraph may seem a truism, but is particularly relevant to the inevitable challenge to begin living with almost no oil. In the beginning of this development, alluded to the complaint of a triple energy crisis. Go to Ann Davies for more information. products and food “, as documented by the Charter of Macchu Pichu, back in 1977. In the days running when the issue of” global climate change “, wins the holders of the mass media and government and academic agendas, it is clear that the three dimensions are indisposable.

The intensive consumption of fossil fuels generates carbon dioxide volumes, which naturally can not be absorbed. This generates changes in climate that not only jeopardize production schemes, but the very possibility of life on the planet. Thus, without anesthesia. This is not a novelty because there were many voices pioneers. Some taken to the banter as the hippie movement in California in the 60s, perhaps offset by the course of the “cold war” developing. Then came others such as the Meadows report, the Gaia hypothesis or the message to the people of Peron, all 1972.

Following this line of reasoning the dynamic regions absorb specialized the qualified migrantes to become each time more. Studies point that the migration provokes an increase of the average incomes of the regions, states and of the Country. The level of the state of Par we can cite Parauapebas that due its specialized industrialization if became a point of attraction of workmanship hand and with this it increased its average income of the city and the state. For Saints and Blacksmith (2006), the movements of migration of man power migram for where the income is bigger, however the expulsora region of has an increase in the work productivity, due to bigger scarcity of factor work and getting a rise in the income. Already for the receiving region a swell of workers will occur and the average income can lower. With this it can be observed that the migration provokes convergence of income between the regions. In accordance with the historical past the incomes of the Brazilian population still suffer some preconceptions from that the man earns more than the woman, the whites earn than black more and aboriginal, diligent of the agricultural zone it earns less than one of the urban zone. This will be verified in the studies of the coefficients of income of the cities of Par (SAINTS and BLACKSMITH, 2006) .5. Objective main METODOLOGIAO of this chapter is to describe of form sucinta the instruments for definition, election, treatment, comparison and criteria of analysis of the dynamics of the productive structure from secondary data of the Ministry of the Work and Job – MTE of the Federal.Esta Government methodology also admits for the results of the research to translate the information geographic it computer and to offer to representative concepts of the reality of the productive structure in study through maps temticos.5.1PROCEDIMENTOS METODOLOGICOSO study of the dynamism of the productive structure of the cities of the State of Par has as proposal to support if in the methods: comparative degree and description.
