A prática do consumo sustentável vem sendo discutida por instituições, governos e especialistas, que defendem que a mudança na forma de consumir pode ajudar a minimizar alguns dos problemas da degradação ambiental. Alguns estudos apontam que cada vez mais consumidores buscam consumir de forma sustentável, porém ainda faltam estudos que comparem grupos com características distintas, a fim de verificar se tais diferenças influenciam seus comportamentos. Neste sentido, esta pesquisa foi feita a partir da Escala de Consumo Sustentável proposta por Ribeiro e Veiga (2011) e aplicada com dois grupos de consumidores, sendo o primeiro formado por 172 pessoas com algum conhecimento em causas ambientais e o segundo formado por 210 pessoas sem comprovação de conhecimento na área. Os resultados apontaram que existe uma tendência ao consumo sustentável entre ambos os grupos de consumidores, porém o nível de engajamento entre as pessoas inseridas em áreas ambientais se mostrou bem maior que as pessoas sem este viés ambiental.

ABSTRACT The practice of sustainable consumption has been discussed by instituitions, governmentes and experts, who defend that change in this form of consumption can help minimize some of the problems of evironmental degradation problems. Some studies indicate that more and more consumers seek to consume in a sustainable way, but there are still studies that compare groups with different characteristics in order to verify if such differences influence their behaviors. In this sense, this research was based on the scale of sustainable consumption proposed by Ribeiro and Veiga (2011) and applied with two groups of consumers, the first one being composed of 172 people with some knowledge of environmental causes and the second group of 210 people without proof of knowledge in the area. The results indicated that there is a trend towards sustainable consumption between both groups of consumers, but the level of engagement among people inserted in environmental areas has shown to be much higher than people without this environmental bias. Keywords: Sustainable consumption. Consumer behavior. Sustainability.

During the 20th century United States consolidated an ecosystem of innovation responsible for ensuring the economic leadership of world capitalism systemic cycle. Even with neoliberal reforms in this ecosystem that were implemented during the Reagan administration the US national innovation system remains competitive because of the solid institutional trajectory it has built.

In the article a new production device is presented that combines the methodologies of high speed forming with conventional hydroforming. The result is a robust production system that can be easy controlled by the use of standard industrial components. The new system can be used as well for high automated production systems for mass production of small tubular and sheet metal parts as for the flexible manufacturing of workpieces with larger dimensions. The device is in principle a hydraulic driven high speed pressure generator that can be mounted directly on a hydroforming tool. Moreover, an additional drive for the axial feed of the tube is installed. In the paper the idea, the design of the device and the technical data is explained. Furthermore, the results of hydroforming experiments are presented and an overview on the specifications and the advantages of the new process is given. The strain rate is measured for an example workpiece and compared to the theoretical value. A first view on the forming limits is a further important topic of the paper. For the investigated copper tube, the forming limits are extended compared to a quasi-static hydroforming test.

Recent public policies in favor of family farming in Uruguay face a lot of tension with the dominant neoliberal logic of Uruguayan agriculture. This paper analyzes the public policy innovations in the management of natural resources, land use and rural development decentralization. It also examines their effects, especially on the area of family livestock farming. The research was conducted by crossing archives analysis and interviews with key decision makers, stakeholders and beneficiaries of the studied policies. Uruguay is in the process of integrating international standards in environmental policies (conservation of water and soil) and regional sustainable development. But the implementation of new regulatory instruments (territorial, environmental, land use, etc.) has problems as they come in tension or conflict with the interests of the corporate sector or with the identity of livestock family farmers.
