Public policies and food security and family farming networks: contributions to the construction of effectiveness indicators.

This work presents a methodology for investigating the performance of public politics regarding food security networks formed in Brazilian municipalities aimed at increasing income and employment in familiar farming. These programs need to further develop the methodologies used for studying their efficiency so that they can reach a new stage in the improvement and use of management tools thereby achieving beteer results of social inclusion and/or food security. This paper constitutes a first effort to bring together indicators for the evaluation of the efficiency of public politicies

Damping behavior of synthetic graphite beams

The main objective of this work was to obtain the damping factor as well as the elasticity modulus (E) of two kinds of synthetic graphite (HLM and ATJ), using the modal analysis technique. Prismatic beams of square section (~ 11 x 11 mm) and length over thickness ratio (L/t) of about 22.7 were tested in the free - free boundary condition. The first four modes of vibration were taken into account in the non-destructive evaluation of the materials. In addition, numerical simulations were also carried out in this investigation. The agreement between the theoretical and the experimental results was quite good. The average values of E and for the HLM graphite were 20% and 90% higher, respectively, than those presented by the ATJ graphite, indicating that the HLM graphite has, proportionally, more damping mechanisms than the ATJ graphite

A COORDENAÇÃO AGROINDUSTRIAL CITRICOLA BRASILEIRA E OS NOVOS RECURSOS DE PODER: DOS POLITICOS AOS JURIDICOS

This work shows that the political and legal resources available to citrus farmers have become as strategic as financial, technological and organizational resources. The study presents an analysis of the Brazilian citrus business governance, which is defined by the use of different strategies among citrus farmers and processing plants: the citrus farmers and their main association use political resources, while some big juice processing plants resort to legal resources. This opposition represents a new obstacle to the achievement of positive results by citrus farmers in the current power network. Court orders demonstrate that orange supply contracts have become a fundamental empowering instrument in the sector, leading to strategic gains for the juice processing plants after four years of significant political conquests by citrus farmers, especially in Sao Paulo state.citrus farmers, power, resources, juice processing plants, citrus business governance, Agribusiness, Agricultural Finance, Industrial Organization,
