A Internet como tecnointeração da aprendizagem: valorização da cultura e identidade juvenil

The present study investigates Internet as technological interaction in the school environment as a resource of the teaching-learning process. It aims to discuss the lack of synchronicity between proposals of educational access for Internet use and types of access and interaction applied by youngsters. For the development of this research, I resorted to a qualitative, descriptive and explanatory research focused on a group whose subjects are youngsters from eleven to fifteen years of age in a catholic school which belongs to a group of private teaching schools in Natal city, Rio Grande do Norte state. As methodological option it focus on a group and the observation of its participation, discourse analysis and ethnography, considering facts and data of the pedagogical practice concerning the focused theme, besides the attempt to know the youngsters everyday at school and the relationship between them and juvenile cultures. It recognizes the existence of two moments of the focused group: the first related to internet use like technological interaction; the second concerns to the way Internet is problematic as technological interaction in classroom learning. While contacting with youngsters, the study discusses the concepts of Media Environments, Culture, Identity, Network, Consumption and Citizenship. It recognizes that it is relevant for the school to consider Internet a pedagogical tool, directed not just at research, but mostly as learning environment and as learning construction in a collaborative way. It points out the need of approach between school and media environment, reevaluating the pedagogical practice, offering a new evaluation proposal (self-evaluation). It suggests a renewal in the teacher's pedagogical practice in the classroom and using Internet, valuing the connection between technological interaction and communication as motivation elements of student s learning construction and their effective participation in decisions involving citizenship. It gives priority to educational work directed at the establishment of dialogic relationship between codes, learning and contents, leading to the new findings domain in the media environment, enabling the development of abilities and performances directed at the recognition and consumption of information from a critical reading of the media

Microbiological Evaluation of Chicken Carcasses in an Immersion Chilling System with Water Renewal at 8 and 16 Hours

Since 2004, Brazil has been the leading exporter of chicken. Because of the importance of this sector in the Brazilian economy, food safety must be ensured by control and monitoring of the production stages susceptible to contamination, such as the chilling process. The goal of this study was to evaluate changes in microbial levels on chicken carcasses and in chilling water after immersion in a chilling system for 8 and 16 h during commercial processing. An objective of the study was to encourage discussion regarding the Brazilian Ministry of Agriculture Livestock and Food Supply regulation that requires chicken processors to completely empty, clean, and disinfect each tank of the chilling system after every 8-h shift. Before and after immersion carcasses were collected and analyzed for mesophilic bacteria, Enterobacteriaceae, conforms, and Escherichia coli. Samples of water from the chilling system were also analyzed for residual free chlorine. The results do not support required emptying of the chiller tank after 8 h; these tanks could be emptied after 16 h. The results for all carcasses tested at the 8- and 16-h time points indicated no significant differences in the microbiological indicators evaluated. These data provide both technical and scientific support for discussing changes in federal law regarding the management of immersion chilling water systems used as part of the poultry processing line.

The global context and the renewal of the United Nations = El contexto global y la renovación de Naciones Unidas

Introducción En esta época posterior a la guerra fría y de creciente globalización, el rol de las Naciones Unidas experimenta constantes redefiniciones y desafíos. El señor Kofi Annan, Secretario General, afirmó que las Naciones Unidas se encuentran hoy en una encrucijada, y que el momento es tan trascendente como lo fue el de su fundación, hace sesenta años. Aunque los principios fundamentales de la democracia, los derechos humanos y el estado de derecho siguen siendo universalmente aceptados y se consideran piedra angular del orden mundial, el Secretario General considera, como otros muchos, que ha llegado el momento de rediseñar su estructura básica para combinar el imperativo de la acción con la necesidad de legitimidad". En este contexto, durante la visita oficial del Secretario General a Chile en noviembre del 2003, la Comisión Económica para América Latina y el Caribe (CEPAL) fue anfitriona de la mesa redonda "El contexto global y la renovación de las Naciones Unidas", en la que participaron la señora Tarja Halonen, Presidenta de la República de Finlandia, el señor Ricardo Lagos, Presidente de la República de Chile, y el señor Annan. Entre los invitados a este acto se encontraban miembros del cuerpo diplomático en Santiago de Chile, destacados intelectuales, representantes de la sociedad civil y académicos que enriquecieron el debate con preguntas y comentarios. Los tres líderes analizaron la situación política, económica y social del mundo de hoy en el contexto del actual proceso de reforma de las Naciones Unidas. Disertaron sobre los desafíos del desarrollo, el multilateralismo, la interdependencia de los países y su necesidad de contar con una participación ciudadana creciente y coherente en los planos local, regional y mundial. Uno de los temas centrales fue el poder, y el modo en que las Naciones Unidas pueden canalizarlo y redistribuirlo con el fin de que su ejercicio sea colectivo y civilizado. Aunque es imposible resolver en una mañana o en una sola reunión estos complejos asuntos, que en ocasiones resultan abrumadores, tenemos la esperanza de que este libro proporcione inspiración, conceptos e ideas que permitan alcanzar soluciones eficaces e innovadoras en el futuro. José Luis Machinea Secretario Ejecutivo CEPAL"

Female germ cell renewal during the annual reproductive cycle in Ostariophysians fish

The objective was to characterize female germ cell renewal during the annual reproductive cycle in two species of ostariophysian fish with distinct reproductive strategies: a siluriform, Pimelodus maculatus, in which oocyte development is group synchronous and the annual reproductive period is short; and a characiform, Serrasalmus maculatus, with asynchronous oocyte development and a prolonged reproductive period. These reproductive strategies result in fish determinate and indeterminate fecundity, respectively. Annual reproductive phases were determined by biometric and histologic analysis of gonads and interpreted according to new proposals for phase classification and stages of oocyte development (with special attention to germinal epithelium activity). Histologically, there were two types of oogonia in the germinal epithelium: single oogonia and those in mitotic proliferation. Oogonial proliferation and their entry into meiosis resulted in formation of cell nests (clusters of cells in the ovarian lamellae). Morphometric analysis was used to estimate germ cell renewal. Based on numbers of single oogonia in the lamellar epithelium, and nests with proliferating oogonia or early prophase oocytes throughout the annual reproductive cycle, oogonial proliferation and entrance into meiosis were more intense during the regenerating phase and developing phase, but decreased sharply (P < 0.05) during the spawning-capable phase. Oogonial proliferation gradually recovered during the regressing phase. We concluded that, independent of species or features of the reproductive cycle, germ cell renewal occurred during the regenerating phase, ensuring availability of eggs for the spawning event. © 2013 Elsevier Inc.

''Bailando com o Senhor'': técnicas corporais de culto e louvor (o êxtase e o transe como técnicas corporais)

A utilização do corpo como instrumento de culto e louvor, em técnicas de cura ou de outros tipos, por católicos carismáticos, que tem despertado tanta atenção, também por sua exibição na mídia (através da atuação de ministros como o padre Marcelo Rossi, no Brasil), permite uma reflexão e um estudo comparativo com outras formas de culto, entre as quais aquelas com características xamânicas, como a pajelança rural amazônica (não indígena) e as religiões afro-brasileiras. Partindo da noção de técnicas corporais, formulada por Marcel Mauss, e lidando com conceitos de autores como Merleau Ponty, Pierre Bourdieu e Thomas Csordas, o artigo analisa parte do material empírico coletado pelo autor em sua pesquisa de campo, que tem como locus a cidade de Belém e a região do Salgado, na Amazônia Oriental brasileira.

The search for Multiple Myeloma Stem cells: molecular characterization and self-renewal mechanisms involved in the disease persistence

The existence of Multiple Myeloma Stem cells (MMSCs)is supposed to be one of the major causes of MM drug-resistance. However, very little is known about the molecular characteristics of MMSCs, even if some studies suggested that these cells resembles the memory B cells. In order to molecularly characterize MMSCs, we isolated the 138+138- population. For each cell fraction we performed a VDJ rearrangement analysis. The complete set of aberrations were performed by SNP Array 6.0 and HG-U133 Plus 2.0 microarray analyses (Affymetrix). The VDJ rearrangement analyses confirmed the clonal relationship between the 138+ clone and the immature clone. Both BM and PBL 138+ clones showed exactly the same genomic macroalterations. In the BM and PBL 138-19+27+ cell fractions several micro-alterations (range: 1-350 Kb) unique of the memory B cells clone were highlighted. Any micro-alterations detected were located out of any genomic variants region and are presumably associated to the MM pathogenesis, as confirmed by the presence of KRAS, WWOX and XIAP genes among the amplified regions. To get insight into the biology of the clonotypic B cell population, we compared the gene expression profile of 8 MM B cells samples 5 donor B cells vs, thus showing a differential expression of 11480 probes (p-value: <0,05). Among the self-renewal mechanisms, we observed the down-regulation of Hedgehog pathway and the iperactivation of Notch and Wnt signaling. Moreover, these immature cells showed a particular phenotype correlated to resistance to proteasome inhibitors (IRE1α-XBP1: -18.0; -19.96. P<0,05). Data suggested that the MM 138+ clone might resume the end of the complex process of myelomagenesis, whereas the memory B cells have some intriguing micro-alterations and a specific transcriptional program, supporting the idea that these post germinal center cells might be involved in the transforming event that originate and sustain the neoplastic clone.
