Abstract: The goal of this study was to evaluate the process of salting and dry salting of fillets in pacu (P. mesopotamicus), from cultivation in cages. Fillet with skin were salted at a rate of 40% of salt in relation of the initial weight, for a period of 10 days. After processing, were evaluated for microbiological and centesimal composition of fillets subjected to salting and determining the concentration of sodium chloride (NaCl) and calculation of income. The centesimal composition were evaluated the protein, ether extract, moisture and ash of the raw material fresh and processed products by salting. The microbiological analysis included the determination of coliforms at 45 ° C, Salmonella and Staphylococcus coagulase positive. The pacus subjected to umided and dry salting were within quality control standards established by the legislation. The content of umided, protein and lipids and chlorides showed differences (P < 0.05) between the processes of salt. However both forms can be used for the development of technological processes of low investment by encouraging new options for fish consumption. O objetivo do presente estudo foi avaliar o processo da salga seca e salga úmida em filés de pacu (P. mesopotamicus), provenientes do cultivo em tanques-rede. Os filés com pele foram salgados na propor o de 40% de sal em rela o ao peso inicial, por um período de 10 dias. Após processamento, foram avaliados os parametros microbiológicos e de composi o centesimal dos filés submetidos a salga, bem como a determina o da concentra o de cloreto de sódio (NaCl) e cálculo de rendimento. Quanto à composi o centesimal foram avaliados os teores de proteína, extrato etéreo, umidade e matéria mineral da matéria-prima in natura e nos produtos processados por salga. As análises microbiológicas compreenderam a determina o de Coliformes a 45°C, Salmonella sp e Staphylococcus coagulase positiva. Os pacus submetidos a salga úmida e seca mantiveram-se dentro dos padr es microbiológicos estabelecidos pela legisla o. Os teores de umidade, proteína e lipídios e cloretos apresentaram diferen as (P < 0,05) entre os processos de salga. No entanto, ambas as formas podem ser utilizadas para o desenvolvimento de processos tecnológicos de baixo investimento incentivando novas op es para o consumo de pescado.

In 1999, the Judaic Education Council of Rio de Janeiro implemented the Educational Innovation Program (EIP) in the Israeli schools of that city so as to meet the new trends in Brazilian education. The present work was designed to evaluate the modifications taking place in the school environment as a result of EIP implementation, a program whose core idea is to work on knowledge building from the Piagetian perspective, active learning in Dewey’s conception, and multiple intelligences as presented by Gardner. In order to assess the chosen program, we used a qualitative approach through semi-structured interviews with the participants and observation of classrooms from the first to the fifth grade of elementary school. The results of our study showed that from the implementation of the program, the professionals involved were more motivated to search for information and update their knowledge so as to meet the differences between students, using a diversity of strategies and dynamic activities which led to encouraging student autonomy as regards their learning. The reported difficulties for the work to proceed were mainly about the schoolwork timetable planned for both the project and the subjects, and teachers having to cover an extensive curriculum, common to other Brazilian schools. In every innovative program, it is important for the professionals involved in it to continually re-evaluate its development, searching for changes or alternatives as difficulties are encountered. The aim of the present paper is to report the main findings of this research, as well as indicate the strengths and precautions to take in educational innovation proposals whose primary focus is classroom innovation.

Sensibilidades e representa??es urbanas na transferência da capital de Minas Gerais
Juli?o, Letícia;
História (S?o Paulo) , 2011, DOI: 10.1590/S0101-90742011000100006
Abstract: this study analyzes the urban representations generated as a consequence of the rupture experienced at the time of the transfer of the capital of minas gerais, in the last decade of the 19th century. the construction of a modern city, belo horizonte, as the new capital of minas gerais, managed to encapsulate the newly-installed brand of republican power in brazil, replacing the old ouro preto, seat of government and indisputable symbol of colonial domain and the administration of the recently-deposed monarchy. the contemporaneous urban images evident in political discourse, in chronicles, newspapers, sundry records and even literary writings are expressive of a new urban sensibility emerging from the process of the capital's transference. apparent are feelings and perceptions that oscillate between nostalgia, enchantment and fear caused by the simultaneous actions of the abandonment of one capital city and the invention of another. many of these images have been incorporated into the urban imagination and still contribute today to the formulations of the identity of both cities - ouro preto and belo horizonte.

Nedel, Letícia Borges;
Horizontes Antropológicos , 2005, DOI: 10.1590/S0104-71832005000100006
Abstract: this paper is about the implantation of a bureaucratic management culture in rio grande do sul - favoring the trajectory of julio de castilhos museum, first museum created in the state at 1903. the analysis is centered on the factors that conditioned the removal of the initial naturalistic reference, inspired by etnografic museums from the beginning of the xxth century, towards a regionalistic perspective of past reconstruction - stated officially in 1954's regiment. from 1952 to 1958, under the direction of the historian and "folk scientist" dante de laytano, the museum becomes a resistent point against the partners of the instituto histórico e geográfico do rio grande do sul (ihgrs) and a recruiting nucleus for comiss?o gaúcha de folclore, official representative of campanha de defesa do folclore brasileiro in the state. at this moment it starts to compete for the institucional allotment of the government with tradicionalistas, grouped around instituto de tradi??es e folclore, created in 1954.

Estudos Históricos (Rio de Janeiro) , 2009, DOI: 10.1590/S0103-21862009000100008
Abstract: research on the institutionalization of a conservationist policy in brazil has privileged either the analysis of discourses on heritage, as formulated by the service for the protection of historical and artistic heritage (sphan), or the examination of measures aimed at protecting architectural heritage, which has constituted the core of governmental action in the field. few studies mention similar endeavors in the field of museums, which constitutes the main objective of this article. i discuss a proposal for the creation of regional museums, taking the state of minas gerais in the 1950s as a case study.
A recep??o da obra de Gilberto Freyre no Rio Grande do Sul
Nedel, Letícia;
Mana , 2007, DOI: 10.1590/S0104-93132007000100004
Abstract: the period in the wake of the novo estado (new state), when revisionism took hold of historiographic production in rio grande do sul, provided the context for the writings of gilberto freyre to acquire a greater influence among the southern intelligentsia. the article investigates the reasons for this delayed alignment with the analytic model of the recife author. at a time marked by the rise of the social sciences and the loss in authority of historical narratives centred on the integrating role of military heroes, local historians and critics combined forces to reverse the motivating factors that had previously separated the textual production of the ?province? from the themes in fashion in the intellectual ?centre? of brazil (rio de janeiro and s?o paulo). this step required closing the gap between history and folklore, meaning the latter was no longer apprehended as a branch of philology or literary regionalism, but as an area of study to be approached from a ?sociological? angle.

Silva,Letícia Krauss;
Ciência & Saúde Coletiva , 2003, DOI: 10.1590/S1413-81232003000200014
Abstract: this work discusses the role of technology assessment in health care, particularly cost-effectiveness, for the planning and management of an evidence-based diffusion and incorporation (financing) of health technologies in the sus. the paper also explains the role of technology assessment in the elaboration of evidence-based clinical practice guidelines, which can serve as important tools for improving quality and efficiency in the sus. initially the objectives, requirements and limitations of the main methodologies used for technology assessment to synthesize knowledge about the implications of the use of technologies are introduced. the relevance, for cost-effectiveness analysis, of the evidence regarding the benefits of the technology, of the use of (incremental) economic, rather than account/administrative, costs, and of making explicit the viewpoints assumed by the analysis are emphasized. a preliminary analysis of the processes of technology diffusion and incorporation in the sus is presented. the importance and possibilities of improving such processes, as well as that related to the elaboration of clinical practice guidelines, through the implementation of well designed and performed technology assessment activities, which take both the government and society's viewpoints, are pointed out.
