Chemical characterization of leaves of organically grown carrot Dacus carota L.) in various stages of development for use as food

In Brazil, street markets and vegetable distributors discard vegetable leaves and stems, including those of carrot (Dacus carota L.). Seeking to reduce the waste of vegetable parts, this study characterized chemically the leaves of organically grown carrot in three stages of development to determine the best time for their removal and consumption as food. The leaves were dehydrated in an oven at 70 °C for 43 hours and analyzed for chemical composition, antioxidant activity, chlorophyll content, fatty acid composition, and also calcium (Ca), sodium (Na), potassium (K), magnesium (Mg), manganese (Mn), iron (Fe), zinc (Zn), and copper (Cu) contents. The analyses indicated 100 days of development as the ideal stage for the removal and consumption of carrot leaves with good antioxidant activity requiring only 63.78 ± 0.5 mg.L-1 methanol leaf extract to inhibit 50% of the concentration of the free radical DPPH (2,2-diphenyl-1picrilidrazil), and total protein and alpha-linolenic acid (18:3 n-3/LNA) contents of 18.23% ± 2.8 and 876.55 ± 20.62 mg.100 g-1 of dry matter, respectively.

Coping with globalization: Asian versus Latin American strategies of development, 1980-2010

When compared to Latin America, Asian economies since 1980 have grown faster and have done so with relatively modest inequalities. Why? A comparison of Asia and Latin America underlines the superiority of the nationalist capitalist model of development, which has often been pursued more explicitly in Asia, over that of a dependent capitalist model, which has often been pursued in Latin America. In comparison to Latin America, the Asian model has facilitated higher and less volatile rates of economic growth and a greater political room to pursue social democratic policies. The "tap root" of these alternate pathways is relative autonomy from global constraints: states and economies in Asia have been more nationalist and autonomous than in Latin America.

Assessing development and the idea of development in the 1950s in Brazil

The decade of 1950s was a crucial period of the industrialization of the Brazilian economy. The dominant school of thought was the national-developmentalism, which was not restricted to the sphere of economic production but also encompassed political and socio-cultural processes of change. Combining repression, persuasion and paternalism, the national state took a significantly political and economic responsibility in the social, material and symbolic modernization during the Vargas and Kubitschek administrations. However, internal disputes, foreign demands and a long legacy of socio-spatial inequalities prevented the achievement of more socially inclusive goals, leading a legacy of unanswered questions that still have currency today.

What Is the Point of Development Ethics?

Research and teaching in societal development ethics face potentially four fundamental types of objection: first, that ethics is obvious already; second, that it is instead impossible, on epistemological grounds; third, that it is theoretically possible but in practice fruitless; and fourth, that it is in any case politically insignificant. The paper presents qualified rebuttals of the four objections. In the process of doing so, it builds up a picture of this field of thought and practice: its modes, methods and alternative forms of organization, and some of its pitfalls and potentials, exemplars and achievements.

The sociology of religion and the 'desecularisation of society'

Neste artigo, pretendo delimitar alguns dos mais importantes e recentes avanços na análise e na teorização que a Sociologia das Religiões sofreu na Alemanha, França e no mundo anglo-saxónico, nomeadamente os conceitos de "new cultural sociology", "new paradigm", e o debate sobre a dessecularização da sociedade. O centro encontra-se na crescente importancia da subjectividade e da espiritualidade. Por forma a não se reduzirem a simples aspectos teóricos, relacionamo-los com as alterações societais das sociedades modernas. Contudo, afirmamos que esta nossa abordagem foca especialmente o fenómeno descrito na Europa Central, assim como nas sociedades anglo-saxónicas. Afastando-nos deste enfoque, desejamos que também em Portugal e no Brasil se desenvolvam estudos sobre estes procesos teóricos e as suas relações com as mudanças nas sociedades.

Repensando la transferencia tecnológica: una reconsideración de la teoría del desarrollo, el Banco Mundial y la tecnología = Rethinking Technology Transfer: A Review of Development

Esta tesis es, ante todo, un examen de la progresión histórica de la Teoría del Desarrollo y de la relación entre Tecnología y Desarrollo desde el inicio enunciativo de las nociones sobre estados “desarrollados” y “subdesarrollados.” Con una revisión pormenorizada de los informes “working papers” del Banco Mundial de los últimos años de la década de los 90 sobre Tecnología y Desarrollo, la tesis tiene como base un estudio histórico que se extiende hasta el presente. Este trabajo es una crítica de las políticas de Desarrollo, y específicamente, una crítica de la ideología de los últimos 50 años, su enfoque pide que el lector examine cómo el Banco Mundial plantea, en el presente, la Transferencia Tecnológica. La tesis se pregunta si el Banco Mundial es un organismo “actualizado” acerca de su visión en torno al Desarrollo, y busca examinar como la Tecnología presenta desafíos significativos para el futuro de las Relaciones Internacionales, así como de las relaciones entre los estados ricos y los estados pobres tecnológicamente hablando.
