PSEUDO: uma análise sociocognitiva sobre insinceridades, mentiras e crimes de fraude

The objective of this work is to analyze the phenomenon of lying, highlighting some uses and social consequences. Lies are a ubiquitous phenomenon, and in many cases they even promote social harmony. Furthermore, telling lies is an expression of individuality: it is the expression of relative autonomy that the subject has towards their social environment allowing them to defend their most personal interests. The work also aims to examine the concept of habitus applied to the social production of lies. Thus, the liars produce their lies aiming to obtain certain effects on their audiences. There are certain social cognitive principles that structure the kind of lie that is usually told to the public. Finally, the perpetrators of crimes of fraud and other deceptive practices may suffer a criminal prosecution because the damage they cause affects important social values recognized by the state, and are not restricted to the victim‟s chagrin. In the most common forms of fraud, the crooks make tempting offers to victims exploiting some of their standardized behaviors and reactions. To understand the fragility of the victims to scams is an attempt to understand how a social phenomenon as usual as is the lie can still surprise and cause perplexity

O ser elástico, mola, agulha, trepidação: expressões do homoerotismo em Fernando Pessoa

This Masters thesis investigates and analyzes the homoerotic expressions in Fernando Pessoa s poetry and in his heteronyms : Álvaro de Campos, Alberto Caeiro and Ricardo Reis. Through the elaboration of deceptive strategies as a way to escape from the insults and the constraints, the poet by means of creative runaway lines builds up a homoerotic poetry that differ from the established patterns and representational models of the literature. We can find, bearing in mind a problematic sexuality which overflows in the various I s, of the sinuous identities and the movable boundaries, and intense mask games. They become real in poems, especially by means of sensations, yielding the possibility of a queer discourse and generating a homoerotic poetry. Pessoa s homoerotism is, thus, presented amid friendly relationships, smooth spaces, of heterotrophy of the city, or others space and the closet s aesthetics. Based on this, it is noted the articulations of a performance gender as body scripture and inscription, thus establishing a physical-writing which reveals a transgressive sexuality, with multiple entrances and exits, affirmations and denials that originate paradoxes. In this matter, we develop links between Foucault conceptions (2010a, 2010b, 2011) towards the history of sexuality, friendship and the power-knowledge relations with traces of significance and subjectivity, in processes of faciality and BwO (Body-without-Organs) in Deleuze and Guattari (1996). We still consider the ontological questionings towards the Gay dimension in Eribon (2008) and we raise aspects concerning the construction of the idea of masculinity in Bourdieu (2010). Finally, we base ourselves on Sedgwick s 1993 closet epistemological approach, as well as on Butler s 2012 gender and performance theory, also going through a few Bataille 1987 passages about erotism, that redimension the homoaffective images of the Portuguese poet

Genética e biologia reprodutiva de vriesea minarum (Bromeliaceae): em busca de estratégias de conservação no quadrilátero ferrífero, minas gerais

Vriesea minarum is a rupiculous bromeliad species, with naturally fragmented populations, restricted to the Iron Quadrangle, Minas Gerais, Brazil. It is a threatened species, which is suffering from habitat loss due to the growth of cities and mining activities. The knowledge of genetic variability in plant populations is one of the main branches of conservation genetics, linking genetic data to conservation strategies while the knowledge about plant reproductive biology can aid in understanding key aspects of their life story, as well as in the comprehension of their distribution and survival strategies. Thus, the study of diversity, richness, and genetic structure, as well as the reproductive biology of populations of V. minarum can contribute to the development of conservation actions. Chapter 1 presents the transferability of 14 microsatellite loci for V. minarum. Among the results of this chapter, we highlight the successful transferability of 10 microsatellite loci described for other species of Bromeliaceae, all of which are polymorphic. In Chapter 2, we present the genetic analyses of 12 populations of V. minarum that are distributed throughout the Iron Quadrangle. We used the 10 microsatellite loci tested in Chapter 1. The results show a low population structuring (Fst = 0.088), but with different values of genetic richness (mean = 2.566) and gene diversity (mean = 0.635) for all populations; and a high inbreeding coefficient (Gis = 0.376). These may be the result of pollinators action and/or efficient seed dispersal, thus allowing a high connectivity among populations of naturally fragmented outcrops. The reproductive biology and floral morphology of a population of V. minarum, located in the Parque Estadual da Serra do Rola-Moça, are studied in Chapter 3. This reserve is the only public environmental protection area where the species occurs. As a result of field experiments and observations, we found that the species has its flowering period from January to March, with flowers that last for two days and that it has a mixed pollination syndrome. It is primarily alogamous, but also has the capacity to be self-ferilized. It is expected that data obtained in chapters 1, 2 and 3 serve as basis for other studies with species from the ferruginous rocky fields, since until now, to our knowledge, there are no other survey of endemic species from the Iron Quadrangle, seeking to merge the genetic knowledge, with the data of the reproductive biology, with the ultimate aim of biodiversity conservation. Considering the great habitat loss for the species by mining, it becomes crucial to analyze the creation of new protected areas for its conservation
