Os estilos de liderança nas organizações não governamentais da região metropolitana de Belém

This study aimed to analyze the leadership style adopted by managers of nongovernmental organizations in the metropolitan region of Belem on the theory of Hersey and Blanchard. This theory is called situational leadership ranks E1, E2, E3, E4 and the styles of leadership and maturity in parallel classes M1, M2, M3 and M4. This study examined the relationship of leadership styles with the maturity of work, identified the relationship of leadership styles as related to psychological maturity and job maturity and psychological maturity. The main objectives were to analyze and relate leadership styles with the maturity of the leaders and understand the phenomenon of leadership from the self-perception of those who lead the organizations studied. To achieve the objectives we used a questionnaire already validated the theory of situational leadership and applied in 320 non-governmental organizations in the metropolitan region of Belem The methodology was quantitative, descriptive and exploratory. The analysis was by descriptive statistics and inferential statistics for univariate and bivariate form, applying the chi-square, the V Crammer and Spearman correlation. The data analysis shows safety, attested to the frequencies, and average margin of error and after application of the tests it was found that a relationship between the leadership style of work with the maturity and psychological maturity. The managers of nongovernmental organizations practicing various styles of leadership and focus on the quadrant of high maturity. It was diagnosed when the manager uses only one style of leadership was the predominance of E3 "share or support", which represents 24% of the sample. As uses two styles of leadership is the predominance of E3 and E2, which represents 76%. So the managers of nongovernmental organizations in the metropolitan region of Belem, practicing a style of leadership support, sharing ideas for decision making using a democratic style

Volatilidade dos retornos e governança: um estudo de eventos da crise do subprime

The financial crisis that occurred between the years 2007 and 2008, known as the subprime crisis, has highlighted the governance of companies in Brazil and worldwide. To monitor the financial risk, quantitative tools of risk management were created in the 1990s, after several financial disasters. The market turmoil has also led companies to invest in the development and use of information, which are applied as tools to support process control and decision making. Numerous empirical studies on informational efficiency of the market have been made inside and outside Brazil, revealing whether the prices reflect the information available instantly. The creation of different levels of corporate governance on BOVESPA, in 2000, made the firms had greater impairment in relation to its shareholders with greater transparency in their information. The purpose of this study is to analyze how the subprime financial crisis has affected, between January 2007 and December 2009, the volatility of stock returns in the BM&BOVESPA of companies with greater liquidity at different levels of corporate governance. From studies of time series and through the studies of events, econometric tests were performed by the EVIEWS, and through the results obtained it became evident that the adoption of good practices of corporate governance affect the volatility of returns of companies

Efeitos da temperatura do ar, linhagem e período do dia nas freqüências de ocorrências e tempos de expressão comportamental de matrizes pesadas

Ajustes de comportamento podem ocorrer rapidamente e a custo menor do que os ajustes fisiológicos. Considerando o comportamento social, é sugestivo que a freqüência e a intensidade de interações agressivas, o total de coesão social e a extensão de vícios sociais possam ser utilizados para avaliação de bem-estar. Esta pesquisa apresenta uma análise das interações entre os fatores experimentais, como temperatura, linhagem e período do dia, nos comportamentos de matrizes pesadas alojadas em câmara climática, buscando evidenciar as diferentes reações das aves submetidas a distintas condições ambientais. Os resultados encontrados mostraram diferenças significativas entre os comportamentos expressos pelas diferentes linhagens, reforçando a necessidade do monitoramento em tempo real do bem-estar de matrizes pesadas em alojamentos comerciais, dada a complexidade com que as variáveis ambientais interferem no bem-estar. A pesquisa permitiu concluir também que a avaliação do bem-estar de matrizes pesadas deve considerar o período do dia na observação dos comportamentos.

Application of fuzzy logic for the evaluation of livestock slaughtering

A lógica fuzzy admite infinitos valores lógicos intermediários entre o falso e o verdadeiro. Com esse princípio, foi elaborado neste trabalho um sistema baseado em regras fuzzy, que indicam o índice de massa corporal de animais ruminantes com objetivo de obter o melhor momento para o abate. O sistema fuzzy desenvolvido teve como entradas as variáveis massa e altura, e a saída um novo índice de massa corporal, denominado Índice de Massa Corporal Fuzzy (IMC Fuzzy), que poderá servir como um sistema de detecção do momento de abate de bovinos, comparando-os entre si através das variáveis linguísticas )Muito BaixaM, ,BaixaB, ,MédiaM, ,AltaA e Muito AltaM. Para a demonstração e aplicação da utilização deste sistema fuzzy, foi feita uma análise de 147 vacas da raça Nelore, determinando os valores do IMC Fuzzy para cada animal e indicando a situação de massa corpórea de todo o rebanho. A validação realizada do sistema foi baseado em uma análise estatística, utilizando o coeficiente de correlação de Pearson 0,923, representando alta correlação positiva e indicando que o método proposto está adequado. Desta forma, o presente método possibilita a avaliação do rebanho, comparando cada animal do rebanho com seus pares do grupo, fornecendo desta forma um método quantitativo de tomada de decisão para o pecuarista. Também é possível concluir que o presente trabalho estabeleceu um método computacional baseado na lógica fuzzy capaz de imitar parte do raciocínio humano e interpretar o índice de massa corporal de qualquer tipo de espécie bovina e em qualquer região do País.

Efeitos da dessecação com glyphosate e chlorimuron-ethyl na comunidade infestante e na produtividade da soja

O efeito de dessecantes sobre o período anterior à interferência (PAI) pode auxiliar na tomada de decisão para o manejo das plantas daninhas. O objetivo desta pesquisa foi verificar se a adição de chlorimuron-ethyl ao glyphosate, para dessecação em pré-semeadura, altera a extensão do PAI na soja. O experimento foi realizado em Jaboticabal-SP, Brasil, submetendo-se o cultivar Monsoy 7908RR a oito períodos de convivência com plantas daninhas, além de testemunhas no mato e no limpo, nos quais foram aplicados dois grupos de tratamentos: glyphosate e glyphosate + chlorimuron-ethyl. em cada período, foram calculados o índice de importância relativa e os índices de diversidade e equitabilidade; por meio da análise de regressão dos dados de produtividade de grãos, determinou-se o PAI. Digitaria insularis, Acanthospermum hispidum, Raphanus raphanistrum e Commelina benghalensis apresentaram maior importância relativa. Os índices de diversidade e equitabilidade oscilaram durante os períodos, e a diferença entre as plantas daninhas fundamentou-se no acúmulo de massa seca. O PAI na soja no tratamento com glyphosate foi de 37 dias após a semeadura (DAS) e de 51 DAS naquele com glyphosate + chlorimuron-ethyl. A adição de chlorimuron-ethyl ao glyphosate permite que a cultura conviva mais tempo com as plantas daninhas sem que ocorra redução significativa na produtividade.

Entre a potência e o ato: atitudes políticas e percepções de mobilização em Natal e Porto Alegre

The recent democratic process in Brazil made it as element for its consolidation the idea of participation. It requires a state model that included on its agenda democratic society participation in decision-making process, and a society that has as a principle based participatory civic consciousness. Therefore, this study aims to analyze the level of political participation in two Brazilian state capitals , Natal and Porto Alegre. Data were obtained through quantitative data from the application of 384 questionnaires in both capitals. We chose some variables that will form the basis for our study; Duties of a good citizen, a good citizen rights, Confidence, Index of socialization, exposure to media, degree of interest in politics; Mobilization; Associations. Already qualitative research sought to address the political, cultural and institutional of the two municipalities

Dimensionamento de amostras para monitoramento do ácaro da leprose Brevipalpus phoenicis (Geijskes, 1939) em citros

O controle do ácaro Brevipalpus phoenicis (Geijskes, 1939), transmissor do vírus da leprose, deve ser realizado quando sua população atinge o nível de ação, obtido pelo monitoramento de sua população, por meio de amostragens. Objetivou-se determinar o tamanho da amostra aceitável para estimar a população do ácaro, para posterior tomada de decisão. O experimento foi realizado na Fazenda Cambuhy, Matão - SP, no ano agrícola 2003-2004. Escolheu-se ao acaso um talhão da variedade Valência, com oito anos de idade, plantada no espaçamento 7x3,5m, com 2.480 plantas. Nesse talhão, foram inspecionados 1; 2; 3; 5; 10 e 100% das plantas, o que corresponde a 25; 50; 74; 124; 248 e 2.480 plantas, respectivamente, em caminhamento no sentido das linhas de plantio. Foram amostrados 3 frutos ou, na ausência destes, eram analisados ramos. de acordo com os resultados obtidos, observa-se que a porcentagem de erro na estimativa da média para a porcentagem de frutos com presença de ácaros, quando se amostra apenas 1% das plantas (25 plantas), é de 50%, ou seja, para uma infestação de 10%, a variação da porcentagem de frutos infestados estaria entre 5 e 15%, levando o produtor a subestimar ou a superestimar o nível de infestação, aumentando os gastos com pulverizações desnecessárias ou um controle ineficiente do ácaro. Para que o erro na amostragem fique dentro da situação aceitável, de 20 a 30% (em média 25%) de erro, deveriam ser amostradas 105 plantas. Na porcentagem de frutos com mais de 10 ácaros, verifica-se que, para a situação aceitável (20 a 30%), devem ser inspecionadas 540 plantas.

Influência do cultivar, do tipo de folha e do tempo de cultivo na medida indireta da clorofila (spad) em mudas de goiabeira

A análise foliar de nitrogênio, comumente empregada em laboratórios de rotina, é destrutiva e nem sempre rápida, obstante para a tomada de decisão. Objetivou-se com a pesquisa estudar as medidas SPAD, em mudas de goiabeira (Psidium guajava L.) cultivada em solução nutritiva completa, observando-se as diferenças entre cultivares, épocas de amostragem e tipos de folhas avaliadas. O delineamento foi inteiramente casualizado, com quatro repetições, em parcelas sub-subdivididas. Assim, foi utilizada como parcela as duas cultivares de goiabeira (Paluma e Século XXI), como subparcelas os tipos de folhas (+1, +2 e +3) e, cinco épocas de amostragem ao longo do período experimental (60, 75, 90, 105 e 120 dias, após o transplantio de mudas) Concluiu-se que a leitura SPAD em mudas de goiabeira é influenciada pela cultivar, tipo de folha e época de amostragem. O terceiro par de folhas mostrou-se mais adequado para avaliar o estado nutricional do nitrogênio nas mudas de goiabeira a partir da leitura SPAD. As cultivares de goiabeira apresentaram diferença na leitura SPAD apenas aos 60 e 90 dias após o transplantio, independentemente do tipo de folha.

Democracia participativa e regulação econômica: uma questão de legitimidade

This work presents an analysis about the legitimation of independent regulatory commission`s rulemaking power by participation procedure. It is observed that political and administrative decentralization and fragmentation of State, with the purpose of approaching citizens and provide, more efficiently, the functions acquired by the passage of the Welfare State, leads to a deficit of legitimacy (democratic crisis), which is noticeable in the making of legal norms by directors of independent regulatory commission to regulate specific economic sector. However, we understand that this crisis stems from the observation of the contemporary world from dogmas and legal institutions of the eighteenth century, without their evolution and adaptation to the modern world. The legitimacy must be perceived as the justification of power, relation command /obedience, which, from the Modern State, has the democracy as standard. Therefore, just as the world has evolved and demanded political and administrative decentralization to accompany him, it is necessary to the development of the idea of representative democracy (formal legitimacy) to participatory democracy (legitimacy stuff). Legitimacy is not confused with the legality: as the legality is on observance to internal legal system, the "rules of play"; legitimacy, as inputs to be fed into this system, the selection of the different expectations in the environment. Nevertheless, the legitimacy will take place by legality, through introduction of rational and communicative procedures: procedures get fundamental importance because these will be the means to select the expectations to be introduced in the legal system in order to make decisions more fair, rational and qualified towards society. Thus, it is necessary to its opening to the environment for dialogue with the government. In this context, we try to make an analysis of constitutional norms based on systematic and teleological interpretation of these norms to build these arguments. According to the Constitution of 1988, participatory democracy is a result of the democratic principle (sole paragraph of art. 1 of the Constitution), and it is an expression of citizenship and political pluralism, both foundations of Republic (respectively Art. 1st, inc . V and II of the Constitution), as well as the national consciousness. From another point of view, that principle consists of an evolution in the management public affairs (principle of Republic). The right of interested participate in the rulemaking process derives both the principle of popular participation (part of the democratic principle) and the republican principle as the due process constitutional (art. 5, LIV and LV, CF/88) and the right to petition (Art . 5 °, inc. XXXIV, "a", CF/88), and it is the duty of the State not only be open to participation and encourage it. Ignoring stakeholder involvement in procedures and / or expressions compiled can be causes of invalidation of the rule of law produced by addiction of procedure, motive, motivation and/or because of the administrative act. Finally, we conclude that the involvement of stakeholders in the process of making rules within the independent regulatory commission is the legitimacy and the validity of rules; and that, despite of the expressions do not bind the decision making, they will enter the system as juridical fact, balancing the field of technical discretionary of agencies

Estimativa da erodibilidade do solo para fins conservacionistas na microbacia córrego do Tijuco, SP

The soil erodibility factor is represented by the integrated effect of processes that regulate the water infiltration, soil resistance and the transport of soil particles. Therefore, this study had as objective to estimate the soil erodibility in the Corrego do Tijuco watershed, São Paulo State, Brazil, for guiding farmers in decision making for application of techniques for soil conservation. The soil samples were collected in a regular spacing of 500 m, resulting in a total of 310 points in a 0-20.0 m depth in an area of approximately 8,000 ha. For the estimation of soil erodibility (K) was applied a mathematical model which takes into account the soil organic matter content, the sand and silt size fractions, the soil permeability, and the particle mean diameter for each point of soil sampling. Estimated values greater than 0.040 Mg ha h ha(-1) MJ(-1) mm(-1) were considered very high for this factor. In areas with greater degree of erodibility occurs the Argisols order predominance, that shows high susceptibility to the development of interrill erosion due to its remarkable performance in relation to textural gradient, thereby, the interrill erosion rates can be very intensive due to rapid saturation of upper horizon, increasing the erosion process. At the Latosols (Oxisols) areas were also observed high soil erodibility values that under inappropriate conditions of soil occupation, concentrating runoff of rain water, leading to appear deep gullies.

Formação moral das crianças: construção de regras fundamentais aos valores do Movimento dos Trabalhadores Rurais Sem Terra (MST)

The acquiring process of morals on a person is one of the most important aspects of his Social Identity. The basis for his ethics and moral choices are built when he interacts with the world. A child that interacts with participants of Movimento Sem Terra (MST) movement that fights for the Land Reform and the transformation of the society may have the opportunities to acquire the culture, morals and ethics of this movement. Based on this understanding, this work intends to comprehend how children think and incorporate the rules that are the base of the values and principles of MST, considering the diversity of the situations, the limits and the possibilities to experience these values in their everyday life in the Movement. To understand how the process of cognitive construction of the rules takes place in a child, it is important to consider the theories of Jean Piaget. According to him, morals development follows a sequence: the anomie (0 to 2 years old), marked by the absence of rules; the heteronomy (2 to 6/7 years old), where takes place the adoption of rules due to exterior obedience, such as a relative, an institution or a movement; and the autonomy (from 6/7 years old on), in which rules are considered legitimate. All the children in this research have relatives working at MST. The research has two parts. We have first observed the behavior of three groups of children (beyond six years old) while they were involved on their normal activities (kindergarten) activities. On the second moment, we have interviewed 20 children (between 3 and 10 years old). We used flashcards containing scenes; we also told stories and asked moral questions involving the character s behavior. We have noticed the unilateral respect and extern coercion are between the definers of the moral decisions of a child. The empathy and the reduction of the egocentrism help seeing the situation of the point of view of other, although it doesn t mean that one is going to accept others point of view. In the taking decision of the child other factors are also considered such as the space of socialization (family, school). Though the children don t work or take part at MST activities, they have already opinions about involved people behaviors. The interaction with relatives and teachers is one of the most important aspects to encourage them elaborate moral understandings according to the ethics of this movement

Conselho de Escola: cenários e desafios de uma escola pública de Natal

This dissertation work studies the Board of Director , created in 1995, in the public schools of the Rio Grande do Norte. It aims to analyze if the creation of this collegiate at Berilo Wanderley State School contributes to accomplish the participation of school segments, democratizing the decision-making in the interior of the institution. This research configures itself as a study of case with information collected together to the representatives of Board through of semi-structuralized interviews. Also they had been essential in the investigation , the informal talks and the registered direct comments in a field diary. For the data analysis we contemplate the following dimensions of the object: the institutionalization process of the Board at Berilo Wanderley State School; the insertion form of the representatives in the collegiate one; the participation of the members in the Board decisions ; the Board s role in the school management and the Board as democratization space. Based in the theoretical and empirical information that we made use, we look for to identify the limits and possibilities of the Board performance in a state public school. The research results indicate that the institutionalization of the Board of Director at the Berilo Wanderley State School presents limits to materialize an effective participation of school community in the essential decisions to the functioning of the school. Also it was possible to underline the fragility of an understanding on the part of school community, the potentialities that the Board in the process of democratization of the school has, translated in the discrepancy between the saying and making of the council members. It can be highlighted that the Board in the school only exists to correspond to a educational policy guideline, with a little significant role , without corresponding to the democratizing possibilities of the collegiate participation. In spite of all the evidenced debilities in the Board of Director experience of the Wanderley Berilo State School , it is worth clarifying that the actor participation, for more limited than either, it represents new something in the setting of the school. In this direction we detach the importance to invest in the improvement of the Board s role, because it can form itself in an educative space for the building of democratic practices in the scope of the school
