Efeito dos andr��genos na estabiliza����o da prefer��ncia manual em machos adultos de sagui comum (Callithrix jacchus)

The role of steroids hormones on the behavior of vertebrates have been described as organizational and activational effects. These actions occur in different periods of the ontogenetic development as fetal, early post natal and during puberty (organizational effect) or modifying the expression of behavioral patterns during time life (activational effects). Studies on brain lateralization in hand use in human and non-human primates have shown that sexual hormones seems to participate in the process of handedness strength that begins in the puberal period and is stabilized at the adult age. The aim of this study was to investigate in adult male Callithrix jacchus if the strength of use of the hand in common marmoset adult male is stable (organizational effect) or androgens variations could affect its stability (activational effect). The preferential use of one hand in 14 common marmoset (Callithrix jacchus was studied in two contexts: (1) spontaneous holding food and directing the food to mouth (feeding episodes), and (2) forced reaching food tests where the animal have to reach the food through a hole within a cover plate with a central hole that allow the use of one hand only to reach the food. The records were made during 5 sessions/20 bouts each during baseline totalizing 100 episodes before two treatments. Firstly it was used GnRH antagonist: a single subcutaneous injection of 100��g de Cetrotide ��� acetate of cetrorrelix (Baxter Oncology GmbH, Germany) (n=10). Secondly, a single GnRH injection of 0.2mg of GnRH (Sigma ��� Aldrich) (n= 8) was used. After injections 20 successful attempts of hand use episodes was recorded in the 1st , 2 nd, 7th, 15th and 30 th days, totalizing in the whole period 100 episodes for each context, after both treatments. Fecal sampling to measure extracted fecal androgens was performed in all days of data collection across the length of the basal and during the experimental periods. Statistical analysis by mixed model, Tukey test to compare mean values after the two treatments, and Levene test to compare mean variance were used, all for p-value < 0.05. In basal phase 6 animals used preferentially the right hand, 5 the left and 3 were ambidextrous. Mean handedness index in basal phase were different from that after both treatment starting at 7th day. Mean variance of handedness index for spontaneous and forced activities does not differs before and after both treatments but the mean values for GnRH index were higher than that observed for its antagonist. These findings suggested that androgens have an activational effect on handedness in adult male C. jacchus

Panorama brasileiro das bibliotecas digitais de teses e disserta����es

As bibliotecas de teses e disserta����es t��m um papel fundamental para o desenvolvimento cient��fico e cultural de um pa��s. Nesse sentido, buscou-se, de modo geral, analisar o panorama brasileiro das bibliotecas digitais de teses e disserta����es. Especificamente, objetivou-se caracterizar a sociedade da informa����o enquanto contexto das BDTD; caracterizar os v��rios tipos de bibliotecas surgidos a partir da inser����o das novas tecnologias de informa����o e comunica����o; identificar as diretrizes norteadoras da implanta����o de BDTD; e levantar as BDTD existentes no Brasil. Para tato, al��m de levantamento bibliogr��fico, realizou-se uma pesquisa nos sites de institui����es de ensino superior brasileiras que j�� disp��e de bibliotecas digitais de teses e disserta����es em funcionamento.

Fatores de sucesso no desenvolvimento de novos produtos em pequenas empresas: um estudo de caso em um fabricante de equipamentos para g��s natural veicular

This study presents itself as a contribution to the solidification of the Natural Gas industry, within the scope of the development of new products. The goal of this paper is to analyze the factors that lead to the success of new products through the evaluation of the activities done during the process of development of these products in the Natural Gas sector. To achieve this goal a case study was done in a small company of this segment. At first, as a basis for the study, a bibliographical research was done with books, theses, dissertations, monographies, publications in national and international periodicals, congress annals and publications in the internet related to the subject. Afterwards, a case study was done, aiming at the acquisition of further knowledge about the real process of development of products in a small company of the Natural Gas sector, allowing for the performance of the evaluation. The case study was done at Gas Project and Systems do Brasil, a company that works with the development of electronic equipment to the conversion of car engines to natural gas, through direct observations and interviews with the person responsible for the development and management of products. Through the evaluation of the process it was observed that the activities related to it are done in an informal way and some activities are considered unnecessary for their success. The results also suggest an emphasis in the technological activities, something that was not observed in the activities related to the market. The instruments used in this evaluation prove to be efficient to evaluate the process of development of new products in other companies, including those of different areas. Taking into account the relevance of the studied theme to the strengthening of the Natural Gas industry, it is necessary to do further complementary studies

Resumo de disserta����es e teses: a estrutura composicional �� luz da An��lise Textual dos Discursos

This doctoral dissertationproposes the description, interpretation and analysis of the compositional structure of thesis and dissertation abstracts, with regard to the linguistic mechanisms that evidence text zones of different typological sequences, such as those of the text plan. Along these lines, the research problem was developed from the notion of compositional structure (sequences and text plans), as one of the levels or plans of text analysis, according to the theoretical framework proposed by Jean-Michel Adam (2011a). The main objective of this study was to recognize how the compositional structure, of thesis and dissertation abstracts, is achieved, with respect to text units and the global organization of this text category. The hypothesis posed in this research posits that specific informational text composition categories of abstracts are necessary to process the representation of the original text and the way in which it makes its meaning. Subsequently, this study is based on the theoretical and methodological framework of Text Linguistics (TL) and, above all, Textual Discourse Analysis (TDA), as we endeavor to understand the organizational structure of abstracts from both a linguistic and textual perspective. This structure involves the text plan of abstracts, with respect to their communicative purpose, i.e, the sharing of scientific information in its standard textual form. Thus, the development of this study, from a theoretical and methodological perspective, is based on the theoretical and descriptive premises from TDA (ADAM, 2011a, 2012; PASSEGGI et al., 2010), and also from TL (BEAUGRANDE; DRESSLER, (2012 [1981]); COSERIU; LAMAS (2010); MARCUSCHI, 2009 [1983]; F��VERO; KOCH, 1994;KOCH, 2006; BENTES, 2004; BENTES; LEITE, 2010), within the field of text studies. The methodology of this study relies on empirical, documental research, which is qualitative, and adopts a descriptive and interpretive approach. From the empirical perspective, our objective is to understand the problems pertaining to the textual composition of abstracts, aiming to elucidate them in light of the theoretical and methodological framework previously mentioned. The corpus of the analysis is comprised of seven abstracts designated for systematic data collection. These texts, written between 2004 and 2011,were selected from Master���s theses and Doctoral dissertations in their electronic version, from the graduate program at the Federal University of Rio Grande do Norte. A thorough review of the literature reveals a clear fluctuation in the terminology of the concept, ���abstract���. The results of the analysis revealed that the abstracts, which comprise the corpus of analysis in this study, in general, present typological heterogeneity, while the text plan remains fixed. Finally, the new knowledge gained in this research contributes both to the understanding of the compositional structure of abstracts as well as their production.
