Abstract:
The objective of this work is to understand how the process of co-creation occurs within the creative industry of video games. For this, concepts of the creative industry, co-creation, information and communication technologies (ICTs) and innovation were studied. Since this is an exploratory and qualitative research, a single case study was chosen as a method. The analysis was done in a Brazilian company that develops games for mobile devices. The results show that the consumer (gamer) participates in value creation in the company’s products, mainly in the initial production stages. In the later phases, after the launch and other steps of the life cycle, although there is a relationship with the users, the joint creation of value is little explored by the organization. Also, it was verified that the co-creation process is supported by different information and communication tools, which provide agility to the process.

Abstract: in this study we investigate the consumer's willingness to try innovative food products in the context of the metropolitan area of porto alegre in brazil and cirencester in england, uk. innovation in the food industry is an important source of differentiation and a value-adding opportunity for managers to develop new products. therefore, the adoption or rejection of innovative food products becomes strategic from a market point-of-view. using the domain specific innovativeness [dsi] scale and the food neophobia scale [fns], two surveys were carried out in brazilian and british universities with 279 and 101 respondents, respectively. consumers were not the most inclined to adopt innovations, but they were not afraid of new foods either, especially in the uk. managers in the food industry could be missing out on opportunities to innovate more. the results provide strategic and unique information about consumers for the food industry, aiming at supporting the development of innovative food products.

Abstract: The advance in cane sugar production is leading the industries of defense to develop researchesof new products from Brazil. The final destination of empty containers of pesticides is a complex procedurethat requires the effective participation of all those who are Ituverava involved in the production chain. In thisstudy it was sought valley to compare the volume returned plants Ituverava Central by Rosary Valley, AltaMogiana, Cosan and Buriti plants during the period 2004 to 2007. Analized data were analyzed during theperiod 2004 to 2007, concerning the delivery it of empty containers of pesticides collected by the four plantsin Central Ituverava-SP. It was evaluated the volume in tonnes, annually, in the four plants, received by theCentral which were tabulated and compared lamang them other. It was observed that Vale do Rosario showeda steady increase in the collection of such packaging, basically doubling this volume from 2004 to 2007. Theother Plants also showed an increase in its collection, however there was a variation of this amount from one year to another, more obvious in Usinas Cosan and Buriti. The usina Buriti, in spite of showing a collection, alsoshowed an increasing, decreasing only in 2007. Broadly speaking, the volume of packaging discarded by Usinashas increased in recent years, showing greater commitment of this link in the chain with the process of finaldestination and, thus, contributing to the increase in the number of packages collected by the Center Ituverava.O avan o na produ o de cana-de-a úcar está levando as indústrias de defensivos a desenvolverempesquisas de novos produtos a partir do Brasil.

Abstract: the concentration of orthophosphate ions released from fe-k-p compounds (fe3kh8(po4)6 .6h2o and fe3kh14(po4)8 .4h2o) present in superphosphates increases with ph, which initially suggests that the agronomic effectiveness of p fertilizers containing high amounts of these compounds would also increase with soil ph but studies considering activity, instead of concentration, are necessary. with this purpose, both compounds were synthesized under laboratory conditions, characterized by elemental chemical analysis, optical microscopy, x ray diffractometry, scanning electron microscopy (sem) and energy dispersive spectroscopy (eds), and used in a solubility study. solutions of 0.01, 0.05 and 0.1 mol l-1 nacl with ph adjusted to 3.0, 4.0, 5.0, 5.5, 6.0, 6.5, 7.0 and 7.5 were prepared for the solubility study of h8-syn, h14-syn and a phosphate rock (pr) from brazil. the orthophosphate activity as h2po4- and hpo42- was calculated in each situation as related to ph and ionic strength using software minteq. the remaining precipitates after equilibrium were chemically analyzed and subjected to x ray, sem and eds. results of chemical analysis and instrumental techniques confirmed the preparation method. the activity of orthophosphate ions of both compounds tended to decrease under increasing ph and/or ionic strength of the solution, which in turn suggests that an increase in the solution ph does not necessarily promote an increase in the p bioavailability for plant uptake. this can be important when evaluating agronomic data of p fertilizers with high contents of these two fe-k-p compounds.
