Lyra, Maria C. D. P.;
Estudos de Psicologia (Natal) , 2006, DOI: 10.1590/S1413-294X2006000100004
Abstract: theoretical and methodological dimensions of scientific research need to be coherent. to illustrate such requirement we first present the eea model, applied to the study of the process of development of mother-infant communication system and to the emergence of the dialogical self is studied. this model integrates three developmental patterns of organization of the mother-infant communication system: establishment, extension and abbreviation (eea). subsequently, we present, discuss and justify the conceptual basis and the two theoretical-methodological perspectives that give support for this model, dynamic systems and dialogism according to bakhtin.

Abstract: we present the empirical characteristics of the eea model, applied to study the development of the mother-infant communication process and the emergence of the self. we introduce the definitions, unit of analysis, and suggested applications. this model integrates three developmental patterns of organization of the mother-infant communication system: establishment, extension and abbreviation (eea). we present the basic concepts (process, irreversible time, historicity, system of relationships, individual, and "virtual reality") and the two theoretical-methodological perspectives giving support to the model, dynamic systems and dialogism, principally from bakhtin's approach.
Desenvolvimento de um sistema de rela??es historicamente construído: contribui??es da comunica??o no início da vida
Lyra, Maria C. D. P.;
Psicologia: Reflex?o e Crítica , 2000, DOI: 10.1590/S0102-79722000000200006
Abstract: this paper attempts to integrate theoretical and methodological assumptions focusing on the development of early communication. two theoretical points are highlighted: the temporal dimension of the developmental phenomenon and the nature of the socio-cultural relationships that characterizes the communication system. in addition, some methodological implications are considered. communication is conceived as a historical and relational or dialogical process. communicative exchanges create a system of relationships from which new communicative patterns emerge. the methodology used comprises longitudinal video records of the mother-infant exchanges-particularly face-to-face and mother-objet-infant-during the first eight months of the infant?s life. multiple cases are analyzed. data analysis from two mother-infant dyads shows moments of quasi-stability and moments of change of the communicative patterns. the history of transformation of these communicative patterns particularizes each mother-infant dyad.
Desenvolvimento de um sistema de rela es historicamente construído: contribui es da comunica o no início da vida
Lyra Maria C. D. P.
Psicologia: Reflex?o e Crítica , 2000,
Abstract: Este trabalho resume um esfor o de integra o entre a perspectiva teórica adotada e a metodologia proposta, focalizando o desenvolvimento de comunica o no início da vida. Dois aspectos teóricos s o destacados: a dimens o temporal do desenvolvimento e a natureza das rela es sócio-culturais que comp em o sistema comunicativo. Algumas implica es metodológicas s o consideradas. A comunica o é concebida como um processo histórico e relacional ou dialógico. As trocas comunicativas s o entendidas como compondo um sistema de rela es que se reorganiza, dando origem a novos padr es de comunica o. A metodologia adotada compreende o registro longitudinal em vídeo das trocas m e-bebê, face-a-face e m e-objeto-bebê, durante os oito primeiros meses de vida do bebê, envolvendo o estudo de múltiplos casos. A análise dos dados de duas díades m e-bebê apresenta momentos de quase-estabilidade e momentos de mudan a dos padr es comunicativos, cuja história de transforma o particulariza cada uma delas.

A concep??o das m?es sobre o desenvolvimento da comunica??o m?e-bebê
Lyra, Maria C. D. P.;Roazzi, Antonio;
Psicologia: Teoria e Pesquisa , 2008, DOI: 10.1590/S0102-37722008000100003
Abstract: two theoretical-methodological distinct perspectives are compared in order to study mother's conceptualization of the process of mother-infant development of communication. based on dynamic systems perspective and relying on longitudinal microanalysis of case studies observations, lyra and collaborators propose the eea model for studying this process of development. this model integrates a sequence of three periods of development of this process, conceived as developmental patterns of organization: establishment, extension and abbreviation (eea). using a "multiple sorting procedure", we investigated mothers' conceptualization of these three periods of development. we examined 48 mothers, from two socioeconomic levels. the results support the eea model confirming: the distinction between face-to-face and the exchanges mediated by the object (mob); the differentiation among the three periods of communication development (eea) in both type of exchanges; and, an order distribution (axial) of these three periods, except for the specific analysis of the mob type of exchanges.
Ultrastructural analysis of the shells of Anodontites trapesialis (Lamarck) and Anodontites elongatus (Swaison) (Mollusca, Bivalvia, Etherioidea) from the Mato Grosso Pantanal Region, Brazil

Revista Brasileira de Zoologia , 2005, DOI: 10.1590/S0101-81752005000300033
Abstract: based on optical and sem microscopic observations, the projections of the outer surface of the periostracum and inner micro-structures of the shell are described and redefined. the outer surface of the periostracum is practically smooth in both species. considering a mesoscopic view of the periostracum, a. trapesialis (lamarck, 1819) presents regular corrugations in the form of radial sequences of arches on the disk region, isolated rays or horizontal sequences of rays on the anterior lower region. a. elongatus presents corrugations formed by series of oblique arches on the disc and oblique rays on the carina. under sem, micro ridges were more evident in a. elongatus, but a wide diversity of shapes and patterns of micro fringes were observed in a. trapesialis, especially in young individuals. considering the profile of the shell layers, the periostracum is relatively thin and apparently simple in a. trapesialis and thinner in a. elongatus. the prismatic layer is thick in both species, consisting of a single series of elongated prisms and wedge-shaped prisms close to the outer surface. the nacreous layer consists of very fine lamellae without pattern or with a slight staircase-like; in a. elongatus this layer is divided by a laminar inclusion of conchiolin. the fringes are abundant and diversified in a. trapesialis, a species less resistant to desiccation due to the presence of a wide intervalvar gap. the existence of a greater density of micro fringes and spikes in juveniles may be related to the orientation of the animal in order to search for an ideal site for development or for escape from regions subject to seasonal droughts, like pantanal.

Abstract:
Increasing Consistency of Disease Biomarker Prediction Across Datasets
Maria D. Chikina, Stuart C. Sealfon
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0091272
Abstract: Microarray studies with human subjects often have limited sample sizes which hampers the ability to detect reliable biomarkers associated with disease and motivates the need to aggregate data across studies. However, human gene expression measurements may be influenced by many non-random factors such as genetics, sample preparations, and tissue heterogeneity. These factors can contribute to a lack of agreement among related studies, limiting the utility of their aggregation. We show that it is feasible to carry out an automatic correction of individual datasets to reduce the effect of such ‘latent variables’ (without prior knowledge of the variables) in such a way that datasets addressing the same condition show better agreement once each is corrected. We build our approach on the method of surrogate variable analysis but we demonstrate that the original algorithm is unsuitable for the analysis of human tissue samples that are mixtures of different cell types. We propose a modification to SVA that is crucial to obtaining the improvement in agreement that we observe. We develop our method on a compendium of multiple sclerosis data and verify it on an independent compendium of Parkinson's disease datasets. In both cases, we show that our method is able to improve agreement across varying study designs, platforms, and tissues. This approach has the potential for wide applicability to any field where lack of inter-study agreement has been a concern.
