Building on some core concepts of dialogic discourse analysis, this article aims to discuss, through an examination of the bestseller lists in Brazil during the years 2000 to 2010, the central features of contemporary mass literature. By the evidence of the prevalence of self-help books, we examine how the phenomenon is consisting. The conclusion that we get is that self-help can be seen both as a discourse genre and as style.

This work intends to “test” two theories about mass cultural products – one that understands them as syncretic and plural and another that sees them as homogenizators and aimed to a mixed audience. We chose Veja magazine as the object of this study and tried to understand how its internal sessions bring in their readers, with the goal of verifying whether readers shared characteristics. In the affirmative case, Veja would be directed to a specific reader; otherwise, it would be a syncretic cultural product. This answer should give us basis to reflect upon the opposition between both ways of thinking about mass culture and help us take a stand on this discussion. Obviously, we do not intend to give a definitive answer to the opposition between these two tendencies. The limits of this work are given by the investigated object itself: we intend to verify empirically how Veja, as a cultural product, solves the contradiction that the co-existence of these two opposite theories point about mass society.

This study aimed to estimate the genetic divergence between Urochloa brizantha ecotypes based on quantitative, qualitative descriptors and their joint analysis to select the promising to release as cultivars of this species. Eight ecotypes (B1, B2, B3, B4, B5, B6, B8) and cultivar 'Marandu' of U. brizantha were implanted into pickets with 1000m2 each, with two repetitions. Five quantitative descriptors were evaluated [leaf area (ALF), length and width of leaf blades (CLF and LLF, respectively), dry mass (MS), mass of dry matter (MMS) and proportion of leaf blade in MS (PLF)] in two forage samples, being a representative of rainfall, in February 2000, and another in the dry period, in August 2000. It was measured the qualitative descriptors: shear strength (RC), volume of accumulated gas in fast and slow fraction (A and B, respectively), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF ), cellulose (CEL), lignin in sulfuric acid (LIG), silica (SIL) and in vitro digestibility of organic matter (IVOMD). There was considerable genetic divergence in U. brizantha ecotypes, especially regarding to quantitative descriptors. Based on the groupings of quantitative, qualitative descriptors and their joint analysis, the grouping containing of B1, B3 and B5 with 'Marandu' can result in promising U. brizantha ecotypes
