Abstract: consider the most important nutrient in the increment of grain gield and also the proteic level, nitrogen (n), in addition of this fact, this nutrient is the component that most increases the production cost of maize crop. this study aimed to verify whether the application of leaf nitrogen influences the accumulation of proteins and parameters of growth of young plants of maize compared to the application of urea via soil. for both, young plants of the hybrid maize br 206 received applications of urea as a source of n via leaf and soil at concentrations of zero, 0.5% and 1.0%. the plants were grown in a greenhouse being held three applications of n, the first for six days after the emergency (dae) in a volume of 10 ml per plant and the following two to 10 and 14 dae with 20 ml each. at 18 dae the plants were collected and analyses proceeded. for plant height, root volum, leaf area, dry weigth of leaf area and root, one verified a higher efficiency of leaf fertilization, mainly at 0,5% level of urea. the application of urea 1,0% via soil caused a significative increase in leaf protein levels. these results suggest that leaf fertilization may be an efficient mode to complement what is uptaken by the roots, although it should not be used as a unique source of inorganic n to the plants.

Abstract: the aim of this work was to quantify the activity of the acid soluble invertase enzymes and insoluble invertase in tubers of potato genotypes: atlantic, pérola, asterix and c-1786-6-94 stored in different temperatures with recondition. one determined the activity of the acid soluble enzymes and insoluble invertase at 0 30 and 60 days of storage. in 30 days of storage the activity of the two enzymes was stimulated by the temperature at 4oc. the recondition from 4o c to 20o c reduced the activity of the insoluble and acid soluble invertase in all cultivars, however in different way among them. the storage at 12oc and the reconditioned from 12o c to 20o c had little influence on the activity of the acid soluble invertase. the activity of the insoluble invertase under 12o c was increased at 30 and 60 days of recondition in c-1786-6-94 clone and atlantic cultivar. the storage at 20oc did not alter the activity of the acid soluble invertase enzyme and insoluble invertase for the cultivars studied.
A crise financeira sem mistérios: Convergência dos dramas econ?micos, sociais e ambientais
Dowbor,Ladislau;
Economia Global e Gest?o , 2008,
Abstract: the workings of the 2008 financial crisis are not very misterious. a mixture of greed, a good dose of outright fraud, and blatantly absent or corrupt regulation. the paper starts presenting the mechanisms of the financial machine, including the institutions supposed to regulate it. it then concentrates on the impacts - who pays for what - and presents the results in terms of income concentration, followed by a few pages on the specific situation of the brazilian financial intermediation system. the last part of the paper presents two groups of responses: on one hand, the ideas concerning the improvement of the regulatory framework, emitted by analysts or institutions interested in maintaining the system while making it more efficient; on the other hand, the views of those who consider that the present crisis is an opportunity to restructure the system, showing that the crisis of the financial system is in fact a part of the larger picture, that involves the social and environmental dramas.

Abstract: as the value of goods and services moves from material to knowledge content, the rules of the game are changing. knowledge can be easily shared, for the benefit of all, and trying to prevent the natural curiosity we all feel in understanding how things happen, as well as the pleasure of creating and sharing cultural innovation, simply makes no sense. the different stakeholders of the creative process have a very legitimate right to earn their living, but certainly not by placing tollbooths at every step of innovation. we need more creativity in the rules of innovation. the present paper is an attempt to make good sense of the contributions of manuel castells on the network society, of alvin toffler on the megatrends of the knowledge society, of lawrence lessig on the future of ideas, of andré gorz on the creative economy, of jeremy rifkin on the era of access, of eric raymond on the connectivity culture, of pierre lévy on the concept of collective intelligence, of joseph stiglitz on the limitations of the patent system, of hazel henderson on the ?win-win? collaborative process, of james boyle on the rules of the new game, for it is a new game, and just looking for ?pirates? and ?criminals? is not helping.

Inova??o social e sustentabilidade
Dowbor,Ladislau;
Economia Global e Gest?o , 2007,
Abstract: technology is moving fast, but the corresponding forms of social management are not. the result is that we have efficient corporations (outputs) with an overall negative result (outcomes) in terms of climate change, income inequality and destruction of natural resources. this is linked to systemic loss of productivity in the use of labor, credit, social policies and technology itself. the main suggested alternatives are linked to improved accounting systems, more democratic governance both in the public and private spheres, as well as more dynamic participation of civil society organizations.
Educa??o e apropria??o da realidade local

Abstract: it is essential for children to feel that the years they spend in school help them understand the reality they face in their daily lives. children, more than adults who had the opportunity to travel, see the world in comparison with the city or neighborhood where they live. the space they refer to is local space. it may be wise to forbid children to play in a stream in the city. but understanding that particular stream and why it is polluted, and who pollutes it and how, allows them to anchor abstract knowledge in the concrete reality they know by experience. besides, how can we expect adults to participate in the development of their regions if they have never studied anything about them? we produce children who know the length of the nile, but are incapable of reading a city map when adults, who never studied the potentials and problems the reality they will have to face. we may follow the example of a small place in the northeast, pintadas, where the children are now taught the characteristics of the "semi-árido", of the concrete problems dry regions present in such fields as agriculture, watersheds, environment and so forth. the author of this paper is an economist convinced that in this era of knowledge economy we need to share knowledge in a more balanced way. teaching children to understand their own space can be a powerful instrument to promote children?s interest and adult citizenship.
Tendências da gest?o social

Abstract: capitalism is a good system when production is concerned, but not good enough a system if we want adequate distribution. and a system that produces well, but does not distribute accordingly, is structurally unbalanced. we need alternatives. what we have had up to now are not alternatives, but simplifications, with statism on one side, and liberalism on the other, redemption being expected to come either from the bourgeoisie or from the proletariat, depending on the political views. this debate will continue, but reality has changed. economic growth is obviously not sufficient, assuming it exists. no modern economic activity can be stimulated if we do not have the corresponding investment in people, through health, education, culture, leisure and so on. social activities are no longer a complement to banking and industry. they have become central to the economy itself. in the u.s., the new economic locomotive is not the car industry, but health, representing 14% of gdp. while social services have become central in modern economies, they still have to find their management paradigm. huge, centralized state burocracies are not responsive enough, while privatization has led to dramatic abuse. the lack of specific management responses to the new demands of social services has become a key problem both in avanced and developing economies.

Finalmente, aborda as alternativas na linha dos novos indicadores de riqueza, da democratiza o do governo, da democratiza o das corpora es e da participa o organizada da sociedade civil, sempre visando enfrentar os desafios da desigualdade e do meio-ambiente. Technology is moving fast, but the corresponding forms of social management are not. The result is that we have efficient corporations (outputs) with an overall negative result (outcomes) in terms of climate change, income inequality and destruction of natural resources. This is linked to systemic loss of productivity in the use of labor, credit, social policies and technology itself. The main suggested alternatives are linked to improved accounting systems, more democratic governance both in the public and private spheres, as well as more dynamic participation of civil society organizations.
