Início da função gonadal no sagui comum (Callithrix jacchus): diferenças entre gêneros

Os primatas não humanos, como Callithrix jacchus vêm sendo utilizados com maior frequência em pesquisa biomédica e, recentemente, nosso laboratório propôs uma nova classificação para monitorar com mais detalhes as modificações comportamentais e hormonais relacionadas ao desenvolvimento. O presente trabalho monitorou os níveis de hormônios gonadais de 4 machos e 6 fêmeas de C. jacchus durante as fases juvenil I e II e subadulta (dos 5 aos 15 meses). Os resultados apontaram que os níveis de progesterona nas fêmeas e andrógenas nos machos foram estatisticamente mais elevados nos estágios juvenil II e subadulto, respectivamente, em relação ao estágio juvenil I. Estes achados indicam que, de acordo com a nova classificação, foi possível observar que o funcionamento gonadal se instala mais cedo nas fêmeas

Gêneros do discurso e escrita: o que as coleções didáticas de português (des)prestigiam no ensino da produção textual?

Through the examination of official indicators, it can be observed that writing is pointed out as one of the main problems concerning formal basic education. However, this teaching-learning object is one of the central objectives at school, having an essential role in different curricular components as well as in the interaction demands required by society. Such paradox indicates, therefore, the relevance of investigations which analyze the intrinsic elements of child development as written text producer. Hence, the main purpose of this research consists of analyzing the treatment given to the types of discourse and the teaching situations in which the written text are produced, concerning Portuguese language didactic material collections approved by Programa Nacional do Livro Didático (PNLD 2010) the Brazilian program of didactic book and worked at elementary school. Such materials correspond to the collections adopted in municipal education system schools from Natal, RN which were below the official education indicator IDEB 2009. Thus, the questions that guide this work are: 1. During writing production lessons, is the diversity of types of discourse effectively worked on didactic collections? 2. Which are the types of discourse and the social spheres prioritized when teaching writing production? 3. How is the situation addressed in the production of the written text should be produced? For this research, we retook the authors Bakhtin, Bunzen, Faraco, Freire, Rodrigues, Rojo, Schneuwly e Dolz and we made a list of all types of discourse and spheres contemplated in the propositions of the writing production in didactical books, concerning the eight collections which compounds the first moment of analysis. Then, we verified how the situation of production is oriented by examining two didactic collections if and how they express the elements referring to the social-historical, functional and linguistic-discursive context of the text to be produced. The data obtained indicate: lack of diversification of types of discourse in the collection that compounds the Aggregate Sample of the research; the conception of a diversity based on the didactic of visiting; the recognition of all canonical and hegemonic types of text as one of the privileged objects of study; the centralization on the standard variety of the language and the devaluation of the representative types of cultural diversity; the shortage of productions which retrace to written language related to different technologies of communication and information; and the little emphasis on the types of discourse related to public language practices. As for the situations of production, it is observed the predominance of the school as a producer of dialogic relationships, whose propositions present, for example, text addressees, enunciative positions, support and contexts of restricted circulation, especially at school. Two divergent situations are observed among the collections: the lack of a work in which the situation of production is under the perspective of the types of discourse as object of teaching-learning; the concept of the types of discourse as object of reflection, presenting a differentiated didactic orientation towards the situation of production. This research contributes, therefore, with a mapping of the existence and the treatment of the types of discourse on propositions of writing production in didactic books; with the critical analysis of the approach of written activities, considering the elements of the historical-social, functional and linguistic-discursive context; thus, through teaching, research and public policies, use and selection of didactic material for the area

Formação docente e gêneros discursivos:o dizer, o saber e o fazer

This master dissertation presented to the Language Studies Post-Graduation Program of the Federal University of Rio Grande do Norte aims present an analysis about the initial teacher training, the knowledge about discursive genres and its usage in basic education professional classrooms. Therefore, it was analyzed, from teachers of fourth and fifth grades of elementary schools, if the initial training provides enough useful tools to be applied in Portuguese classes, i.e., if during the teacher training process concepts of discursive genres emerge, which of these concepts can be noticed and how this knowledge helps teachers in their classrooms. In order to achieve this aim, it was taken into account studies about the initial teacher training, about the knowledge diversity that is part of the teaching knowledge and also about discursive genres based on Bakhtin‟s conception, which is used in the Parâmetros Curriculares Nacionais (PCN). This research is qualitative of interpretative basis and has taken an opened questions questionnaire and classroom observations with audio recording data as corpus of analysis. As results of this investigation, it is possible to emphasize that the initial teacher training has left some gaps in discursive genres concepts and usage in Portuguese classes, that it is not only one kind of knowledge that compound the teacher knowledge and, because of this, working with disciplinarians knowledge, specially about discursive genres, is to emphasize one among many others.

A Transposição Didádica dos Gêneros do domínio do discursivo publicitários nos livros didáticos

Advertising text has been a subject of many investigations, because of its multimodal universe. Embodied by a linguistic and discursive materiality laying on scene persuasion, argumentation and power imagery of multissemiotics elements, the advertising text acts as an instrument of power, creating and destroying, promising and denying (CARVALHO, 2007). Advertising not only invites us to act for it, but directs us to look at it. It was under this moving look - of charm and interrogations - that discussions raised in this research were born. Investigations are directed to the school environment, in special, for the discursive advertising domain in Portuguese Language Textbook. It is from this environment that was born our research whose main objective is to analyze how does the didactic transposition of textual genres, described by Marcuschi (2008) as belonging to the "advertising" discourse domain (focusing on advertising genre) in didactic books teaching Portuguese Language before and after the advent of the PCN. Textbooks taken as reference for the study are historically situated in the 90s of the twentieth century and 10 century. Such books refer to elected 7th and 8th grades, currently corresponding to the 8th and 9th grades of elementary school. The choice is justified by the fact that in these Textbook teaching series the presence of advertising domain is recurrent and "didactized". In addition, we are also concerned in analyzing books that circulated around us and our regional reality. Hence, we elected books that were used by two public high schools: Municipal School Clementina Ana da Conceição in Jaçanã city in the Rio Grande do Norte state, State School for Elementary and High school Carlota Barreira in Areia city, Paraíba state. In our research the following categories of analysis were highlighted: (1) presence of advertising in DB, (2) fluctuation terminology: concepts and classifications; (3) The complexity of concepts facilitation, (4) what they propagate, and from which nature are the explored advertisements. From our analysis, we observe how the treatment of textual "advertising" genres have been inserted into Textbooks, and how occurs, in general, their didactic transposition. Focusing on the issue of fluctuating terminology, we noted the difficulty in drawing boundaries between the genres of advertising domain in the Textbooks. However, this also would result in the complexity - in the field of scientific knowledge - of delimiting genres of the same domain. To accomplish our studies, it was required a thorough and systematic dialogue with theories regarding the concept of "Didactic Transposition", due to the theoretical Chevallard Yves (1991), research on the textual genres - Bezerra (2005), Marcuschi (2008), Bazerman (2005), Swales (2004), among others - and studies involving the field of "Advertising" - Sandmann (2002), Carvalho (2007) and others

A leitura e a produção textual no ensino fundamental I: uma proposta de como trabalhar com os gêneros textuais

The little interest in reading and the large presence of deviations in writing observed in the texts of students of the 5th grade of a public school in RN, led us to question the motives of this problem. Thus, the idea to organize and develop teaching sequences with a variety of possibilities of reading and production through the text genres. The practice with the textual genres in elementary school extends the use of reading and writing and improves the quality of learning. In this way, the school, as one of the most active spheres in social practices of the language, we justify this work with the use of text genres as facilitators for teaching and learning the mother tongue. For this purpose, we draw as the main objective to talk about the work with textual genres from the development of didactic sequences, as well as encourage students to take a more reflexive attitude toward language and its uses, as discursive social practices. The development of the study with the text genres was made through the application of didactic sequences in the school context of elementary school classes, from 5th grade. Specifically were chosen, the letter, note, music, poetry, fable and the tale. The study is anchored in the reflections of the following theorists and researchers: Bakhtin (2011), Miller (1994), Marcuschi (2008) and Bronckart (1999) on the text genres; Marcuschi (2005) and Dolz and Schneuwly (2004) that approve a teaching-learning proposal focused on textual genres, giving a meaning to language in the construction of the knowledge and Dolz and Schneuwly (2004) regarding the didactic sequence; other theoretical orientations: PCN (1998), Lerner (2005), among others. The methodology followed the action research guidelines, in a qualitative approach perspective. The instruments of research included questionnaire, observations, readings and productions. The results pointed the students' interest in relation to the activities developed in the didactic sequences and consequently improvement in the students‘ own writings. In this sense, we reiterate the need to contamplate in the teaching activities the diversity of texts and genres and, not only due to its social relevance, therefore the student should be able to use the language in various way and adapt their texts to situations of oral and written interlocution.
