Organização das assembléias de peixes em riachos da bacia do rio Iguatemi, Estado do Mato Grosso do Sul

Aiming to describe the patterns of the fish assemblages organization in streams of the Iguatemi River basin we sampled streams with seine nets and sieves from November/1999 to August/2000. We collected 567 individuals distributed in 24 species. We detected statistically significant influence of the streams characteristics upon species diversity. The species composition was hardly explained by the physical and chemical characteristics of the streams. Then we detected significant influence of the fish ecomorphology in the species occurrence (Mantel r = -0.34; P = 0.04), but not in the distribution of its abundance (Mantel r = -0.21; P = 0.07). We verified through the species co-occurrence index (C-score) that its composition in the studied streams is stochastic.

Organização celular dos testículos em Hylidae e leptodactylidae, no Pantanal (Estado do Mato Grosso do Sul, Brasil)

The objective of this work was to make a comparative analysis of germ cell organization at different stages of cellular differentiation in adult males of Dendropsophus nanus (Boulenger, 1889), Pseudis limellum (Cope, 1862), P. paradoxa (Linnaeus, 1758), and Scinax acuminatus (Cope, 1862), belonging to the family Hylidae; and Leptodactylus chaquensis (Cei, 1950) and L. podicipinus (Cope, 1862), belonging to the family Leptodactylidae, collected in the Pantanal and in Serra da Bodoquena, Mato Grosso do Sul State, Brazil. The testes were removed and fixed, dehydrated in a graded series of ethanol and embedded in methacrylate glycol resin (Historesin Leica®). The sections were stained by 1% toluidine blue and observed under light microscope. It was detected that all individual of the Hylidae family show, throughout the year, the presence of all germ cell types of spermatogenesis. However, all Leptodactylidae family individuals only show the presence of all germ cell types during the rainy season. The variations of characteristics in seminiferous epithelium organization, as well as the evident difference in the amount of spermatozoa inside the tubules, are evidence that the anurans in this work show different forms of spermatogenesis development throughout the year: the cycle is continuous for the Hylidae family, and discontinuous with explosive release of spermatozoa for the Leptodactylidae family.

Fatores preditivos do sucesso da inseminação intrauterina: A morfologia espermática de acordo com o novo manual de laboratório da Organização Mundial de Saúde

Objective: The aim of our study was to assess the likelihood of IUI success as a function of the previously described predictive factors, including sperm morphology according to the new reference values defined by WHO. Material and Methods: This retrospective study enrolled 300 couples which underwent IUI. Regression analyses were used to correlate maternal age, number of preovulatory follicles on the day of hCG administration, number of inseminated motile sperm, and normal sperm morphology with clinical pregnancy. Results are expressed as odds ratio (OR) with 95% of confidence intervals (CI). Results: Women older than 35 years showed a lower pregnancy rate (6.5% vs 18.2%, p=0.017). Logistic regression models confirmed the lower chance of pregnancy occurrence for older women (OR: 0.39; CI: 0.16-0.96; p=0.040). The presence of two or more preovulatory follicles on the day of hCG administration resulted in higher pregnancy rate when compared to cases in which only one preovulatory follicle was present (18.6% vs 8.2%, p=0.011). The regression model showed a more than two fold increase on probability of pregnancy when two or more preovulatory follicles were detected (OR: 2.58; CI: 1.22-5.46, p=0.013). The number of inseminated motile sperm positively influenced pregnancy occurrence (OR: 1.47; CI: 0.88-3.14, p=0.027). Similar pregnancy rates were observed when semen samples were classified as having normal or abnormal morphology (10.6% vs 10.2%, p=0.936). Conclusion: Our results demonstrate that sperm morphological normalcy, according to the new reference value, has no predictive value on IUI outcomes. © Todos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.

Bibliotecas, arquivos e museus como centros de referência na dimensão cultural das comunidades

With the evolution of the organizations theory, new management practices have transformed the institutions. The improvement of these management practices in cultural unities (UCs) is constant, and interacts in the international axis, since each unity increasingly communicate with other. As a reflection of organizational administrative practices, UCs had developed and assumed the organizational theories to make easy a framework for effective management practices. Comprehending the importance of the studies on UCs requires both a new approach of existing public politics for this field, and the recognition of the Information Science knowledge on area. In this way, it was planned to develop a model constituting a tool for managers in these institutions through the experience of laboratory works carried out with researchers from the European community. Libraries and museums are institutions that operate in the social process of their communities and the archives establish their structural spaces in parallel with the political, economic and social environments of the communities, translate the society and its organic sphere of informational performance. The information transposes a cyclical and essential role for the arrangement of the effective and necessary record to the organizational process and the institutional growth. Studies of this nature contribute to value a economy based on knowledge, and its production emphasizes the human capital that permeates the condition of the information in support for the development of communities and the growth of the organizational environment in political, social and cultural spheres.

O processo de (re)construção da teoria do conceito no domínio de Organização do Conhecimento: Uma visão dialógica

The search for a dialogical interpretation on the concept theory is the purpose of this paper. It uses the concept of dialogism, proposed by Bakhtin, which refers to the interaction occurring among the social actors in the process of (re)construction of language. Starting from the analysis of texts on concept theory authored by Dahlberg, Hjorland, Tennis and Tennis and Sutton, the convergent, divergent and complementary aspects related to the concepts advocated by the authors are discussed. The analysis revealed that, although these concepts have been built individually, they are reflections of distinct currents of thought and of the historical moments that have influenced each author's ideas. It can be argued, therefore, that the studied concepts were developed on dialogue with other authors and among themselves.

Relações teóricas da organização do conhecimento com as abordagens de catalogação de assunto, indexação e análise documental: Uma análise de domínio da revista Scire (1995-2010)

Considering knowledge organization and representation as a theoretical line used by Information Science to face the subject approach to information, in a dialogical relation with subject cataloguing, indexing and analyse documentaire, this article carries out a domain-analysis of Scire journal (1995-2010) in order to identify the scientific production in the mentionned theoretical lines as well as their relationships. Scire constitutes an environment where members of the different paradigms have found an space to relate each other.
