Vinculando a etnoictiologia às evidências biológicas para explicar o declínio da riqueza da ictiofauna neotropical

The diversity of fish species from South America has been affected by various anthropogenic practices. Some studies have reported the influence that illegal transferring or introduction of exotic species have on the trophic webs of continental lakes. The loss of diversity on fish populations and consequent impacts on fishery are commonly evidenced in these cases. The Brazilian Northeast has ponds for which exotic Amazonian species were transferred as Extremoz Lake. These environments serve as study models for comparison and investigation about the possible impacts of these introductions. We tested the hypothesis that loss of species that this trend can be related with the insertion of the genus Cichla, commonly documented as top predator in its endemic environment. Possible structural causes that interfere in other processes such as migration were also investigated. Thus, the local ecological knowledge of fishermen and a current ecotrophic model were used. We took samples of phytoplankton, zooplankton and fishes during two annual cycles. Concurrently, we made interviews with the fishing community. In fact, there are relations between the loss of fish and the insertion of peacock bass in Extremoz Lake. However, Cichla kelberi was not indicated as primary factor to explain fish species decline. The construction of bridges located in the Rio Doce was main factor for respondents and what explains loss of species. The migration of saltwater fish and / or from the river to Extremoz Lake is hindered by the unsuitability of the crossing-streams that are under these structures. According to the ecotrophic model Hoplias malabaricus was considered key-species and Cichla kelberi top predator. This last trend was similarly noticed in the stomach and local ecological knowledge of fishermen analysis. Overfishing simulations to Cichla kelberi resulted that only raising its captures in 200%, other native species would increase their biomass values only 15 to 30% (in 6 years).The negative effects of the alien species introduction without prior studies and lack of investments in appropriating these constructions to the needs of the fish fauna structures seem to act simultaneously. Both are causing the decline of fish species richness and consequent local artisanal fishery collapse

Transporte eletrônico e propriedades termodinâmicas de nanobiomoléculas

We use a tight-binding formulation to investigate the transmissivity and the currentvoltage (I_V) characteristics of sequences of double-strand DNA molecules. In order to reveal the relevance of the underlying correlations in the nucleotides distribution, we compare theresults for the genomic DNA sequence with those of arti_cial sequences (the long-range correlated Fibonacci and RudinShapiro one) and a random sequence, which is a kind of prototype of a short-range correlated system. The random sequence is presented here with the same _rst neighbors pair correlations of the human DNA sequence. We found that the long-range character of the correlations is important to the transmissivity spectra, although the I_V curves seem to be mostly inuenced by the short-range correlations. We also analyze in this work the electronic and thermal properties along an _-helix sequence obtained from an _3 peptide which has the uni-dimensional sequence (Leu-Glu-Thr- Leu-Ala-Lys-Ala)3. An ab initio quantum chemical calculation procedure is used to obtain the highest occupied molecular orbital (HOMO) as well as their charge transfer integrals, when the _-helix sequence forms two di_erent variants with (the so-called 5Q variant) and without (the 7Q variant) _brous assemblies that can be observed by transmission electron microscopy. The di_erence between the two structures is that the 5Q (7Q) structure have Ala ! Gln substitution at the 5th (7th) position, respectively. We estimate theoretically the density of states as well as the electronic transmission spectra for the peptides using a tight-binding Hamiltonian model together with the Dyson's equation. Besides, we solve the time dependent Schrodinger equation to compute the spread of an initially localized wave-packet. We also compute the localization length in the _nite _-helix segment and the quantum especi_c heat. Keeping in mind that _brous protein can be associated with diseases, the important di_erences observed in the present vi electronic transport studies encourage us to suggest this method as a molecular diagnostic tool

Mapa dos programas sociais: transferência de renda e dinâmicas sociais no Rio Grande do Norte (2000-2007)

The question of evaluating the fight against poverty in a given society is very complex task, considering the range of factors that permeate, such as education, culture and economy itself. Come hence the relevance of the theme and its constant presence in discussions on the fruits of public policies, institutional structure and economic development which are the guiding elements of this work, and noted that seeks to highlight the social demographics and most important, the most significant trends and issues pertaining to her. The assessment was initially made in all the municipalities of Rio Grande do Norte doing a verticalilzação to the municipalities Caicó, Pau dos Ferros, Ipueira and Taboleiro Grande. Highlighting the role of a social policy through government programs, such as the Bolsa Familia Program (PBF), which creates the possibility of changes in the socio demographic profile given the importance that the action of this public policy has in shaping the regional economic reality As well as social programs and actions of the government here reported that generate mobility of people and new social demands, such as rural retirements, the benefit of continuing provision (BPC), the Program for the Eradication of Child Labor (PETI) that put on the market of population living on the margins of various forms of consumption. Accordingly, the socio economic profile of the state shows a significant improvement in their social indicators, vital education and redistribution of income, due to the significant improvement in life expectancy in the fall of school drop-out rate and the drop in indicators of Proportion Poor and destitute of the state. Where the fall in the proportion of poor and indigent is strongly associated with an increase in income, from social programs. With this transfer and redistribution of income can be gauged that occurs a strengthening of local economies and an engagement of families with the conditionalities of social programs and PETI Bolsa Familia. Our research concludes that simply raising the rents caused by transfers, presents relevant impacts on the education of young people in beneficiary families. There is no doubt that the programs of transfer income, no facing the social field, representing a mechanism to decrease the most perverse ills of poverty, social and economic inequality that is hungry. For a significant portion of the Brazilian population living below the poverty line, programs for the transfer of income are expressed directly in improving the material conditions of life and indirectly in improving self-esteem of women and all family members receiving encouraging yet the integration family. Experiments have shown that improvements in health and nutrition can be obtained through the implementation of adequate social policies like the programs of transfer income, while social inclusion and economic does not become full

Do papel atribuído ao papel exercido: a política de formação continuada de alfabetizadores em municípios cearenses

The paper is about the role played by the municipalities in the literacy teacher continuing education policies. It is a research conducted in Ceará municipalities, Brazil, having the period between 2003 and 2006 as a contextual sample. The study brings the notion of intergovernmental relations and cooperative mechanisms as theoretical and central tools and, through interrelated stages of bibliographical and document analysis as well as fieldwork, it is carried out the analysis of the interrelation between the municipal policies and the policies developed by the Federal and/or State Government for literacy teacher continuing education. The research reveals that in the field of the realities examined taking care of the literacy teacher continuing education policies is not an exclusive municipal role, but it is a common competence of the federated entities within the Brazilian cooperative federalism.

Os rumos do fundo público no capitalismo contemporâneo: uma análise sobre o financiamento da Política de saúde no estado do Rio Grande do Norte

This work analizes the financing of Health Policies on the state of Rio Grande Do Norte, starting at the presumption that SUS is “Bombarded” by fiscal ajustments, as a neoliberal strategy to face capital crises.The trafectory of the financing of SUS demands the comprehension of two principles which are, in essence, contradictory: the “principle of universatility”, which is caracterized by the uncompromising defence of the fundaments of the Sanitary Reform, and the “principle of containment of social costs”, articulating the macroeconomic policy that has being developed in Brazil since the 1990s and which substantiantes itself on the 2000s.This last defends the reduction of the social costs, the maintanance of primary surplus and the privatization of public social services. Considering these determinations, the objective of this research constitues in bringing a critical reflection sorrounding the financing of the Health Policies on the state of Rio Grande do Norte, on the period from 2004 to 2012.Starting from a bibliografic and documentary research, it sought out to analyze the budget planning forseen on the Budget Guideline Law (LDO) and on the Multiannual Plans (PPA), investigating the reports of the Court of Auditors of the State of RN and gathering information about expenses with health, available on the System of Information About Public Budgeting in Health (SIOPS).The Analises of the data obtained, in light of the theoretic referece chosen, reveals trends in the public budget setting for health on the State of Rio Grande do Norte, which are: a tiny share of investment expenditure on health, when compared to other expenses, the amount used in daily fees and advertising; the high expense in personnel expenses, especially for hiring medical cooperatives;the strong dependence of the state on revenue transferences from the Union; the aplication of resources in actions of other nature considered as health, in exemple of the expenditures undertaken by the budgeting unit Supplying Center S/A (CEASA) on the function of health and subfunction of prophylactic and therapeutic and on the Popular Pharmacy program. Since 2006, expenses refering to Regime Security Servers (RPPA) on the area of health also have being considered as public actions and services in health for constitutional limit ends, beyond the inconsistencies on the PPAs with the actions performed efectively.

Capacidades estatais para implementação de políticas públicas em ambientes federativos: o caso do Programa Bolsa Família

This thesis aims to understand the extent to which state capacities of state governments explain the effectiveness of the implementation of Programa Bolsa Família (PBF) in the Northeast, adopting the implementation of the theory as the main theoretical lens and more specifically the concept of state capacity. Methodologically is a study of public policy evaluation, and categorized as a process of evaluation study or implementation. Given the specificity of the object is classified as a multi case study research covering the states of Sergipe, Rio Grande do Norte and Bahia. In addition to using secondary data, the study used semi-structured interviews with members of Intersectoral Committees responsible for the actions of PBF and the Cadastro Único at the state level, composed of representatives of the areas of the state government of Social Welfare, Education and Health. the main findings related to technical and administrative capacities and policies were found: infrastructure with weakness in human resources, technological and financial resources; intra-governmental coordination with boundaries between PBF and Unified Social Assistance System , and the actions of conditionality of health and Health Unic System Basic Attention; intergovernmental coordination carried out mostly by the distance limitations of displacement and incipient regional decentralization of actions; based monitoring in the municipalities of lower performance and from the parameters placed by the federal government and political capacities; representative political system is hardly accessed by instances of program management; minor social participation and low articulation with related issues advice to PBF; audit control by any outside agencies. The thesis concludes that depending on the capabilities found implementing weaknesses are not unique to the program's actions, but from the very institutional capacity of the systems in which it operates that are the Unified Social Assistance System, the Health Unic System and the Educational System. In other words limitations of their own state capacities of the state governments and the municipal governments of each territory, such as quantitative insufficiency and qualification of human resources, financial and institutional resources, lack instance promoting decentralization (Intergovernmental and intra-governmental) as well the weakness or absence of a network of local social services are also factors that explain the program management performance and state capabilities of arrangements formed by states and municipalities in the PBF, only to partially deal with the complexity of joints involving Implementation of the program with regard to inter and intra-governmental action.

A gestão educacional das secretarias municipais de educação de municípios maranhenses a partir do plano de ações articuladas 2007-2011

The main purpose of this thesis was to analyze educational management of Municipal Departments of Education (SEMED’s) of cities in Maranhão inserted in the Plan of Articulated Actions (2007- 2011). We evidence the role of Union in that public policy. The leading argument is that Brazilian federal government is not demos constraining in relation to its national sub-governments, what makes the central government to enforce, primarily, educational politics like PAR. This kind of politics interferes in the educational management by national sub-governments, turning them into mere executors. By turning them into mere executors, PAR limits their autonomy and over imposes the results-based management as a parameter to improve the education quality. In order to develop the hypothesis, we adopted Political Science as theoretical basis, represented by Federalism Theory as pact which premise is the cooperative pattern of federalism as being the best form of government because it allows a joint decision-making process from the idea of no centralization of power. The methodology was historical materialism, which assumes the totality and contradiction as a form to understand the phenomenon that does not express in direct way its existence, but can be analyzed from such categories that made possible to interpret the reality. So, we used as tools the semistructured interview and documental analyses with triangulation of data. The empirical basis of the research is 04 (four) cities in Maranhão that obey the following criteria: 1. The municipality has to be assigned on the FNDE Resolution nº 29/2007; 2. To present the lowest educational management indexes from the diagnosis made in loco by PAR; 3. To present the lowest financial management indexes based on the diagnosis in loco by PAR. The results suggest that PAR does not effect a resultbased management which are proposed in its legal rules neither the SEMEDs can propose their conception of educational management. That situation creates a hybridism that sometimes turns to managerialism and performativity, sometimes to bureaucracy, sometimes to a total uncoordinated and unarticulated action. In relation to SEMEDs management, this thesis shows that these institutions have no own conception about educational management and end up acting in an uncoordinated and unarticulated way. The thesis concludes that PAR is an over imposition by federal government towards national sub-governments that conflicts with management patterns of those institutions that are used to a less managerial logic. This over imposition makes the Central government to be the center of Brazilian federalism, which is in reality an incomplete pact.

Percepções das relações entre trabalho remunerado e trabalho voluntário: um estudo com voluntários da pastoral da criança

O trabalho é uma atividade de fundamental importância na vida do homem porque é uma condição essencial para sua existência social. Ao longo do tempo o trabalho teve diversas definições e significados, mas na atualidade pode-se dizer que ele sintetiza e satisfaz três necessidades essenciais da natureza humana, a necessidade de subsistir (função econômica), a de criar (função psicológica) e a de colaborar (função social). Nesse contexto a presente pesquisa objetivou compreender as relações estabelecidas entre os trabalhos remunerado e voluntário, na perspectiva de identificar os aspectos convergentes e divergentes dessas atividades, que possam explicar a permanência dos sujeitos nas duas dimensões laborais e ao mesmo tempo entender qual a importância e reflexo que ambas as atividades têm na vida dos entrevistados. Como instrumento de coleta de dados foi utilizado a entrevista semi-estruturada do tipo focalizada. Foram entrevistados nove líderes da Pastoral da Criança no mês de dezembro de 2009 na cidade de Natal/RN. Os dados foram interpretados à luz da análise de conteúdo, proposta por Bardin. Os principais resultados encontrados quanto aos aspectos convergentes do trabalho remunerado foram a importância do salário para prover a sobrevivência, convivência com as pessoas e troca de experiência além do valor do trabalho para manter a dignidade do homem. Os pontos divergentes enquadraram: trabalho como obrigação, competitividade no ambiente laboral e baixa remuneração. Quanto ao trabalho voluntário, os aspectos convergentes emergidos foram a realização pessoal, a solidariedade, o envolvimento com a causa da Pastoral, valorização das coisas que possui diante de outras realidades mais difíceis, reconhecimento e prestígio dos voluntários pelas famílias assistidas, e por fim a visão do trabalho voluntário como complementação da vida. Com relação aos pontos divergentes foram citados a falta de comprometimento de alguns voluntários, bem como a necessidade de adesão de novas pessoas à este tipo de trabalho, limitação de querer fazer mais e não poder, exigências do público assistido e imagem distorcida da missão da Pastoral da Criança por parte das famílias, além da constatação dos níveis de pobreza e injustiça social que geram desigualdades as mais diversas. Sobre os aspectos marcantes para a permanência dos sujeitos nas duas esferas de trabalho, o amor, a dedicação, a realização pessoal foram os motivos mais apontados. Nas relações entre os dois trabalhos, as transferências de valores aparecem como recíprocas e naturais, sendo aproveitados para estabelecê-las o que cada atividade laboral apresenta de melhor. Conclui-se que o altruísmo, a solidariedade, a generosidade, o acolhimento, a paz espiritual, o bem-estar e sobretudo o amor, são sentimentos que sustentam e confortam o homem, cujas relações aparecem de forma expressiva nas falas dos entrevistados e permeando todo o decorrer da pesquisa.

Modelo de decisão multicritério para seleções interciclo das universidades novas: estudo na Universidade Federal do Rio Grande do Norte

The discussions wherein develop proposals for university reform in Brazil include, among other things, the conception of the university titled "New University", whose structural origin comes from the bill of higher education reform and unification of the foundations of education European upper (Bologna process). At its core, the Bologna process has imposed a series of transformations, among which, the promotion of mobility, as a stimulus to interinstitutional cooperation to enable an better and bigger qualification of the students. Nevertheless, what we see is that this point is one of the main points made flawed by Brazilian institutions that have adopted this model of higher education. An example is the Bachelor of Science and Technology - BC&T, Federal University of Rio Grande do Norte - UFRN, where there are problems of the internal order, represented by the problem of the reusing of the disciplines, such also of external order, in cases of transfers interinstitutional. Because of this, and knowing that this is a typical problem in which multiple criteria are involved, the aim of this study is to propose a multicriteria model for selection of interciclo of the BC&T of the UFRN which addresses the issue of mobility. For this, this study was of exploratory and study case nature, use as tools of data collection, the bibliographic and documentary research, as well as semi-structured interviews. For the elaboration of the model, were used the five phases most commonly used in the modeling of problems in operational research in a sample of 91 students of BC&T. As a result, we obtained a model that addresses the issue of internal and external mobility of the school and that, moreover, was also more robust and fair than the current model of BC&T and also what is used in other courses of the UFRN, taking into consideration the expected results by the decision makers
