Custos e rentabilidade da produção de juvenis de tilápia-do-nilo em tanques-rede utilizando-se diferentes densidades de estocagem

Neste trabalho foi realizada a análise econômica da produção de juvenis de tilápia-do-nilo em tanques-rede utilizando-se diferentes densidades de estocagem. O experimento foi desenvolvido em área aquícola, em delineamento de blocos casualizados, com quatro densidades de estocagem (100, 200, 300 e 400 peixes m-3), avaliadas com seis repetições, em dois períodos de criação: de março a abril de 2005 (52 dias - peso inicial de 43,08 ± 2,98 g e peso final de 262,14 ± 47,86 g) e de março a abril de 2006 (58 dias - peso inicial de 43,16 ± 5,34 g e peso final 314,24 ± 73,30 g). Foram avaliadas as seguintes variáveis econômicas: custo da ração mais custo do juvenil dividido pela biomassa, em R$ kg-1; porcentagem do custo da ração por quilo de peixe produzido sobre o preço de venda; porcentagem do custo do juvenil por quilo de peixe produzido sobre o preço de venda e; porcentagem dos custos da ração mais do juvenil por quilo de peixe produzido sobre o preço de venda. da menor densidade de estocagem (100) para a maior (400), ocorreu diminuição no ganho de peso diário e elevação do índice de conversão alimentar aparente, mas essa redução não comprometeu a taxa de sobrevivência. Entretanto, o ganho de biomassa aumentou com o adensamento de peixes. As maiores receitas líquidas foram obtidas nas densidades de estocagem de 100 e 200 peixes m-3. Os preços não remuneraram os custos operacionais (efetivo e total) em maiores densidades (300 e 400 peixes m-3). Os melhores resultados para a produção de juvenis de tilápia-do-nilo foram obtidos com densidades de até 200 peixes m-3.

Proteína e energia na alimentação de pacus criados em tanques-rede

O objetivo neste trabalho foi avaliar o desempenho de pacus (Piaractus mesopotamicus) criados em tanques-rede e alimentados com dietas contendo níveis de proteína bruta (PB) e energia digestível (ED). Foram utilizados 3.960 peixes com 293,38 ± 5,67 g de peso inicial, distribuídos em 18 tanques-rede de 5 m³, com 220 peixes por unidade experimental (44 peixes/m³), em esquema fatorial 3 × 2, composto de três níveis de proteína bruta (25, 30 e 35%) e dois de energia digestível (3.250 e 3.500 kcal/kg). O arraçoamento foi realizado quatro vezes ao dia (às 9 h, 11h30min, 14 h e 17 h) até a saciedade aparente dos animais. Não foram observadas diferenças no ganho de peso, na taxa de sobrevivência, na conversão alimentar aparente nem na taxa de crescimento específico. No entanto, houve diferença na deposição de gordura visceral, que foi maior nos animais alimentados com as rações de maior nível energético. Também não foi observada influência dos níveis de proteína e energia da dieta nos teores de umidade, proteína bruta, matéria mineral e lipídio dos filés. Rações contendo 25% de proteína bruta e 3.250 kcal/kg de energia digestível promovem melhores resultados de desempenho.

Implementação da política de assistência social em Mossoró/RN : uma avaliação a partir dos centros de referência da assistência social

The current National Policy for Social Assistance (PNAS) is the instrument that regulates the organization and procedures of social-welfare actions. Developed and approved in 2004 since the Unified Social Assistance System (ITS) was crated in 2003, it reaffirms the democratic principles of the Social Assistance Organic Law (LOAS) focusing on the universalization of social rights and equality of rights when accessing the social-welfare system. In the SUAS point of view, the PNAS highlights the information, monitoring and evaluation fields for being the best way to assure the regulation, organization and control by the Federal Government paying attention to the principles of decentralization and participation. This political-institutional rearrangement occurs through the pact among all the three federal entities. The pact deals with the implementation of the task. It says that it has to be shared between the federal autonomous entities, established by dividing responsibilities. To the cities, considered as the smallest territorial unit of the federation and closer to the population, was given the primary responsibility, which is to feed and maintain the database of SUAS NETWORK and identify families living in situations of social vulnerability. In addition to these responsibilities, the cities that have full autonomy in the management of their actions, have the responsibility to organize the basic social protection and the special social protection, that using the Center of Social Assistance Reference (CRAS) and the Center of Specialized Social Assistance Reference (CREAS), are responsible for the provision of programs, projects and services that strengthen the family and community; that promote people who are able to enjoy the benefits of the Continuing benefit of Provisions (BPC) and transfer of incomes; that hold the infringed rights on its territory; that maximize the protective role of families and strengthen its users organization. In Mossoró/RN, city classified as autonomous in the social assistance management, has five units of CRAS that, for being public utilities, are considered the main units of basic social protection, since they are responsible for the connection between the other institutions that compose the network of local social protection. Also known as Family House, the CRAS, among other programs and services, offers the Integral Attention to Families Program (PAIF), Juvenile ProJovem Program, socio-educational coexistence services programs, as well as sending people to other public policies and social-welfare services network, provides information, among others. In this large field, social workers are highlighted as keys to implement the policy of social assistance within the city, followed by psychologists and educators. They should be effective public employees, as a solution to ensure that the provision of the services are to be continued, provided to the population living around the units. However, what we can find here is inattention to the standard rules of social assistance, which not only undermines the quality of programs and services, but also the consolidation of policy on welfare as public policy of social rights

Plano de Desenvolvimento da Escola (PDE): o processo de implantação de uma nova proposta de descentralização em duas escolas da rede municipal de ensino de Natal de 1999 a 2002

The 1988 Constitution was the legal marc to define changes in Brazilian State with major importance to the layout of public politician. In that moment of redefinitions e openness to new ways the redemocratization, participation and decentralization of public school had as their starter the elementary school. This work focus on the manage of FUNDESCOLA, particularly one of its politics called PDE (Educational Development Plan) wich purpose is guarantee a better quality in teaching and spread out democracy throughout its methodology. It was chosen two public schools: Professor Ulisses de Góis and Antonio Campos. The theoretical and methodological orientation is based on the theory of participative democracy developed by authors such as Putnam and Pateman. They says that a cultural background precedes individual participation in society. The collected data (educational legislation, surveys with all sectors of schools and technicians of Natal educational secretary, and relevant documents of de institutions) showed that PDE. Implementation had opposite runnings in the schools studied. In one, as a consequence of bad preparations of its teachers to absorve its methodology, PDE failed. In another way, PDE achieved its goals, especially helping the structure of action plans of the school and the administrative organization making possible several pedagogic activities planned. The work concludes that the main factor the failure or success of PDE relies on the organizational (both political and pedagogical) structure of each school. This discovery implies three important guidelines when comes to formulation of public politicians: a) Constitution of school; b) the local actors who manages the actions; c) the colletive interest in taking part of decisions

Indicadores zootécnicos e econômicos da tilapicultura em tanques-rede de diferentes dimensões

The present study aimed to compare the main zootechnical and economic indicators of farming tilapia in superintensive system developed in two different net cages dimensions: 6 and 18 m(3). Were used 12,960 juveniles male reversed Nile tilapia (Oreochromis niloticus), strain supreme, with an initial average weight of 32.0 g (+/- 0.85) for 6 m(3) net cages and 88.5 g (+/- 0.96) for 18 m(3) net cages. The fish were fed three times a day with commercial extruded ration, crude protein levels from 40 to 32%, particle size from 2 to 8 mm and daily feeding rate starting with 8% of live weight (LW), decreasing up to 1% LW. It was conclued that, although no statistical difference in most indicators zootechnical (P>0.05), the production of tilapias in bigger net cages resulted in lower average total cost and higher rentability per kg of fish produced, 34.4% higher, resulting in better profitability.

O amor em tempos de internet: as expectativas amorosas na rede social Badoo

This research aims to examine the phenomenon of sexual relations by observing the Social Network Badoo. As a means to achieve this objective, qualitative in-depth interviews were conducted online. The main question is to understand how the amorous expectations in the liquid modernity are configured. Added to that, there is as analysis categories the insight about relationships and the love experiences provided by the use of the Social Network Badoo. There are three initial hypotheses: 1) a time of transition is experienced, in which the liquid love in the proposed terms by Bauman (2004) was gaining ground and, as consequence, the relationships would be presenting themselves shorter, more open and with another interactive proposals for the relations. 2) The consuming practices of the liquid modernity can interpellate the relational practices molding them according to your logic. 3) It is assumed that the reasoning, inherent to the market, of the use followed by the disposal settles itself in the social behavior and this practice is accentuated by technology, through the use of the internet for the establishment of romantic relationships.the empirical analysis shows that both the vision on relationships as the amorous expectations in liquid modernity have as references the model of solid loving relationship, inherent to the traditional modernity. However it also demonstrates that the romantic experiences and practices refer to the liquid relationship model. Therefore, from these statements it is argued that there is in liquid modernity the cohabitation of the liquid and solid models of romantic relationships. In summary, this research aims to understand the contemporary love relationships across the spectrum of relationships that develop on the Internet Social Network: Badoo

Natal como destino turístico : um estudo das imagens (re)veladas pela mídia, pelos turistas e suas implicações educacionais e culturais

This thesis is a result of a research on Natal/RN as a tourist destination. We understand that cities are chosen as tourist destinations beyond its cartographic localization, from other dimensions of meanings that, in its set, constitute images. These images are, probably, very different of the images constructed by native and resident populations, who possess relations of identity with the place. The knowledge of the meanings that others attribute to this city as tourist destination, bring us near to the symbolic bonds established by individuals or social groups on the act of their choices, as well as bring us near to the interaction process city-tourists where the expectations are confirmed or not. The images divulgated by the media also participate of the complex formation of the tourist image that is being constructed and available for the different public, in different social contexts. The tourism constitutes a symbolic asset of the modern society, being considered by the studious, as one of the most expressive phenomena of the modernity, for involving each year displacement and the interaction of thousand of people of different cultures in the entire world. All this people s mobilization points to practical social related to personal motivations, to the entailed desired to the idea to travel and to exceed borders. It is already consensus that tourism is a phenomenon of economic growth, generating jobs, income, professional, qualification, bringing improvements for the host cities. Since 1995, in Brazil, the tourism as a sector of the economy, passed to be considered one of the national priorities, and in this perspective, the national politics of the tourism invested in infrastructure of Brazilian cities with high tourist potential, objecting to increase the flows of Brazilian and foreign tourists. Owing to this fact, the country still invests in programs of tourist marketing, mainly divulging the images of the natural beauties of Brazil abroad. And for Brazilians, the campaigns appeal to rescue the feeling to be Brazilian, associating the idea to travel and know its country. Natal city possesses an excellent positioning in the tourist marketing, being predominantly divulgated in national and international level, for its naturalistic singularity, where the images of its natural enchantments as warm water beaches, white dunes, warm weather, constant breeze and an always blue sky are shown as the favorite scene on this city. From what was viewed above that the choice of a tourist destination articulates from a determined imaginary of a place, already constructed or in process of construction, we consider the knowledge of this imaginary a basic learning for the population of the city and especially, for educators, in the formation of professionals in this area and for tourism managers, elaborators of public politics. Based on this estimative, we developed this research that had as a general objective to identify the images that illustrate Natal city as a tourist destination - our objective of study, particularly the meanings and senses attributed by the tourist marketing (hotel s folders) and by the tourists that visited the city during this study. The discussions and reflections that had guided this research had been given from the theoretical link between imaginary and social representation, also considering some interfaces between the fields of communication and symbol. From the studied authors, Baczko (1985) clarifies that the study of social imaginary is directed for the mechanisms and structures of the social life, especially for the intervention accomplishes and efficient of the representations and symbols in the practical collectives, as well as in its direction and orientation . Following this same thought, Moscovici (1978) says that the social representation are produced in communicational and symbolic contexts, and these representations once that already constituted circulate socially as almost tangible entities. Based on this fundament and on the analyze of Barthes (1990), particularly in the approach given to the reading of photographic image, we could observe on hotel s folders that each page evidences senses and meanings of functionality of internal and external spaces, pointing to the way of leisure offered by the keepers of city which is the hotels. About, the leisure that they offer, it is directed to young public, giving meaning to the young myth of personalized leisure tourism on children, young and adults images. The image about security that hotels offer and the singular image of Natal city as a paradise place, provide an idealization of pleasure through the sun, dunes, and beaches and also due to the hospitability of the natives who are assigned as educated . For the tourist that participated on this research, Natal city is tied only by the imaginary of leisure and nature which constitute the emotional link of the relation media-city-tourist. And with such force and fullness of directions the city discloses without tensions and contradictions as a place protected by a mythical and sacred aura. The study also demonstrates us that the potiguar culture remains (almost) forgotten, due to the silenced in this imaginary. In this perspective, we highlight that this culture silence is very close related to the disvalue of education in its general meaning. We defend that the imaginary apprehended constitutes a new reading and a new looking and understanding the tourist reality that comes historically consolidating in this city. In this direction, we glimpse that this study and its future dismemberments can collaborate with the process of rescue the cultural values of the potiguar people, in the way that the meaning of tourist may be redefined, and the tourist image of the city can be also disclosed for its identities particularities of its culture

O conceito de morte: significações de professoras dos anos iniciais do ensino fundamental

Cette étude appartient à l un des principaux défis de l éducation dans l actualité qui est la production de connaissances concernant la mort comme objet d investigation théorique et empirique dans le domaine éducationnel. Des recherches récentes signalent le besoin d une éducation contemplant des études sur la mort et montrent l école tel qu un lieu de débats et reflexions à propos de ce thème. Cette reflexion est relevante et fondamentale, étant donné que la mort fait partie du cycle de la vie et se trouve présente dans les contenus scolaires des différents domaines de la connaissance. Ce travail a, donc, l objectif d analyser les signification attribués à ce concept mort et la relation qui s établit entre eux et la pratique des professeurs de l enseignement fondamental. Il adopte en tant que référentiel les principes de la recherche qualitative du type étnographique (André, Chizzotti et Meksenas), dans une approche socio-historique et en ce qui concerne la formation et le développement des concepts (Vygotsky, Kopnin, Guetamanova et Ferreira). La participation des professeurs a été faite par l observation participante, registres en cahier de bord et application d un instrument de construction de données pour l appréhension des significations attribués aux concepts qui sont à la base de la pratique de cinq enseignantes des premières séries de l Enseignement Fondamental d une école publique du réseau d enseignement de l État du Rio Grande do Norte située dans la Zone Sud de Natal. De ce fait, les analyses et les interprétations des observations de la pratique dans la salle de classe et des réponses aux quinze questions liées au thème ont permis de construire les significations des concepts qui appuient les pratiques enseignantes de ces professeurs, tout en mettant en relief la fragmentation et la désarticulation entre les expressions décrites dans les questionnaires et les pratiques développées en salle de clase. Ces reflexions mettent en évidence la nécessité de re-penser l articulation entre l énnoncé et la pratique des professeurs à propos de cette thématique au cours d une formation initiale et continue

Representações sociais de formação continuada: com a palavra as professoras do ensino fundamental da rede pública de Natal RN

Metaphorically, research is presented as a journey by sea, having as object of study the social representations of Continuing Education for teachers of elementary school and as aim, to analyze them in comparison of participants from state and municipal systems, located in Natal-RN, Brazil .They have contributed to the achievement of this objective the voices of 158 teachers, the vast literature on training in professional development and the theoretical formulations proposed by Moscovici and colleagues, with relevance to the Central Nucleus Theory advocated by Abric. The corpus resulting from evocations about continuing education, as well as teachers' justifications were submitted to different computer methods/techniques, through the EVOC ALCESTE Programs, respectively, providing the opportunity to highlight a network of interconnections between the likely core and the production of discourse. Although the educational ideologies that underlie social perception of the state teachers are anchored in New School and technicist concepts and the teachers in the city tend to an ideology of social interaction, the choice of working with the symbolic field identified the political-social commitment of groups with the impacts of training on learning of their students
