Este estudo avalia os impactos das políticas de hard accountability sobre a gestão das escolas estaduais das redes públicas brasileiras. Para isto, foi elaborado um indicador de gestão com base nas informações da Prova Brasil dos anos de 2007 e 2013. Posteriormente, através da metodologia diferenças-em-diferenças, foi estimada a relação entre os programas de incentivo via bonificação e a gestão, isolando-se os efeitos distintos entre escolas por meio de variáveis de controles desenhadas para captar o ambiente escolar. Os resultados sugerem que a hard accountability é estatisticamente significativa sobre a gestão das escolas e seu efeito é negativo. Resultados nessa linha também foram encontrados ao segmentar estas escolas de acordo com a experiência dos diretores e nível de proficiência. Adicionalmente, os impactos da hard accountability e gestão foram estudados tendo a proficiência como variável dependente. A hard accountability apresentou efeito positivo sobre a proficiência do 9º ano em Matemática. O indicador de gestão, por sua vez, mostrou relação positiva com as notas médias de todas as séries e disciplinas avaliadas.

This study examines the factors that influence public managers in the adoption of advanced practices related to Information Security Management. This research used, as the basis of assertions, Security Standard ISO 27001:2005 and theoretical model based on TAM (Technology Acceptance Model) from Venkatesh and Davis (2000). The method adopted was field research of national scope with participation of eighty public administrators from states of Brazil, all of them managers and planners of state governments. The approach was quantitative and research methods were descriptive statistics, factor analysis and multiple linear regression for data analysis. The survey results showed correlation between the constructs of the TAM model (ease of use, perceptions of value, attitude and intention to use) and agreement with the assertions made in accordance with ISO 27001, showing that these factors influence the managers in adoption of such practices. On the other independent variables of the model (organizational profile, demographic profile and managers behavior) no significant correlation was identified with the assertions of the same standard, witch means the need for expansion researches using such constructs. It is hoped that this study may contribute positively to the progress on discussions about Information Security Management, Adoption of Safety Standards and Technology Acceptance Model

This study aimed to measure the perception of maturity project management of state boards of Rio Grande do Norte by the perception of its managers. Argues that project management has been highlighted as a critical factor for the success of any organization, because the projects are directly related to the set of activities that result in organizational innovation as products, services and processes and the improvement of project management is directly aligned with the main pillars of the New Public Management. Methodologically, this is a quantitative research of a descriptive nature in which 161 forms were applied with coordinators and subcoordinators of state departments of Rio Grande do Norte, culminating in a sampling error of less than 6% to 95% confidence according to the procedures finite sampling. The process of tabulation and analysis was done using the package Statistical Package for Social Sciences - SPSS 18.0 and worked with techniques such as mean, standard deviation, frequency distributions, cluster analysis and factor analysis. The results indicate that the levels of maturity in project management in state departments of Rio Grande do Norte is below the national average and that behavioral skills are the main problem for improving management in these departments. It was possible to detect the existence of two groups of different perceptions about the management of projects, indicating, according to the managers, there are islands of excellence in project management in some sectors of the state departments. It was also observed that there are eight factors that affect maturity in project management: Planning and Control , Development of Management Skills , Project Management Environment , Acceptance of the Subject Project Management , Stimulus to Performance , Project Evaluation and Learning , Project Management Office and Visibility of Project Managers . It concludes that the project management in state departments of Rio Grande do Norte has no satisfactory levels of maturity in project management, affecting the levels of efficiency and effectiveness of the state apparatus, which shows that some of the assumptions that guide the New Public Management are not getting the levels of excellence nailed by this management model

Seed germination and seedling establishment are critical processes for commercial plantation and depend directly on reserve mobilization as a source of cellular fuels and biosynthetic precursors. In this way, we investigated the coordination among reserve mobilization, metabolite partitioning, and mobilizing enzyme activities in Moringa oleifera Lam (moringa) an oil-seeded species employed in biofuel production. Seeds were germinated under controlled conditions and seedlings were grown hydroponically at a greenhouse. Samples were harvested at 0, 4, 8, 10, 12, 16, and 20 days after imbibition (DAI). The contents of dry mass (DM), neutral lipids (NL), soluble proteins (SP), starch, total soluble sugars (TSS), non-reducing sugars (NRS), and total free amino acids (TFAA) as the activity of isocitrate lyase (ICL), acid proteases, and amylases were determined. The mobilization of storage proteins was initiated during seed germination whereas the mobilization of storage lipids and starch was triggered throughout seedling establishment although all reserves have been depleted until 20 DAI. The partitioning of DM and metabolites to the roots and the shoots was uneven during seedling establishment. Low shoot/root ratio on the basis of DM could be related to the natural occurrence of moringa in drought climates. In the roots, TSS, NRS, and TFAA were accumulated from 12 to 16 DAI and then were consumed until the end of the experiment. In the shoots, TSS and TFAA were consumed in parallel with NRS accumulation from 12 to 20 DAI. The activity of ICL, acid proteases, and amylases was coordinated with the mobilization of lipids, proteins and starch respectively. Thus, we propose that the patterns of reserve mobilization and metabolite partitioning verified in moringa seem distinct from those found to other tree species and may be involved in metabolic strategies to enable environment colonization

This study deals with Sociology teacher identity issues. This is done considering daily routines of Sociology grade school teachers in the city of Picos in the state of Piauí-Brazil. Thus, the research aims to acknowledge the manner the inter-relations between the teacher s know-how and the process of construction of the professional identity of these teachers occur. It is seen that the discipline of Sociology in this context brings out processes related to inclusion and exclusion once the subject of Sociology is distinguished as unstable in relation to other disciplines. However, in June 2008, the law included the Sociology as a discipline 11,684 mandatory on all high school series.The theoretical and methodological procedures of this research were based on an ethnographic qualitative nature research and enabled a documental analysis. In order to collect data, a semi-structured questionnaire was applied in collective and individual in four state schools in the city of Picos in Piauí. The analysis of the information was based in content analysis from the proposals made by Bardin (1997), and Franco (2008). The information was then organized in knowledge matrixes that allowed the identification of themes divided into two thematic axes: teacher education: the search for sense making in experience and the exercise of teaching as well as the Sociology grade school teacher s daily routine. The research enables the understanding of the senses the subjects have on their own activity since the work deals with concrete situations and experiences in the scholar context. These senses are considered relevant in order to enable a comprehension of the inter-relations that are established between the know-how and the construction of the identity on behalf of these teachers. Almost all of the interviewed subjects did not have a degree in Social Sciences and came from other backgrounds especially ones related to Education. Sociology teachers investigated almost in its entirety, do not have specific training in the social sciences, becoming teachers of Sociology by lack of school and to complete the work load. But, in spite of the difficulties experienced in the practice of the discipline all are in favour of its inclusion in high school. They have a clear vision, that through the work of the theoretical content of the discipline with the daily life of the students by using teaching strategies that add value to the relationship of knowledge that are prepared in society at large, to Sociology provides a critical analysis of the reality in which they are inserted

Buscando-se avaliar morfofisiologicamente a rebrota do capim-mombaça, quatro desfolhas foram impostas ao perfilho principal, sendo estudado o comportamento da planta em termos da taxa de expansão da área foliar, crescimento do sistema radicular, nível de carboidratos totais não estruturais (CTNE) da raiz e do colmo, taxa de crescimento relativo (TCR), taxa de assimilação líquida (TAL) e razão de área foliar (RAF) às idades de 2, 5, 9 e 16 dias após as desfolhas, bem como da taxa fotossintética máxima às idades de 2, 6 e 13 dias das folhas remanescentes à desfolha. As desfolhas foram as seguintes: remoção de todas as lâminas foliares (desfolha total), a remoção da lâmina da folha adulta mais jovem (desfolha superior), a remoção das lâminas das duas folhas adultas mais velhas (desfolha inferior) e controle (sem desfolha), juntamente com o corte dos demais perfilhos, realizado a 8 cm do solo. Foram observadas cinco repetições por tratamento, segundo o delineamento inteiramente casualizado. As folhas adultas não diferiram quanto às taxas fotossintéticas máximas, que exibiram aumento nos primeiros dias após a desfolha, e queda aos 13 dias. A desfolha reduziu os teores de CTNE da base do colmo, principalmente nas plantas sob desfolha total. Comprometimento do crescimento do sistema radicular e do teor de CTNE das raízes foi observado nas plantas sob desfolha total, que também tiveram sua TCR reduzida nos primeiros dias de rebrotação. Entretanto, o aumento na RAF possibilitou a estas plantas recuperação da TCR e alta taxa de expansão da área foliar, igualando a área foliar das demais plantas aos 16 dias de rebrota.

According to the Forest Code of 1965, it is mandatory that every rural property destine part of its land to the establishment of Legal Reserves. When a diagnosis is made over all Brazil, the reality is quite different from what is demanded by law. Therefore, this work, as a general objective, proposes ways of establishing Legal Reserves based on the analysis of the environmental deterioration in a river basin. For this purpose, the environmental deterioration was detected based on three diagnoses: physical-conservational, socioeconomical, and environmental quality. In this way, from a quantitative and qualitative diagnosis, it was possible to identify the main aggressive factors in the studied river basin and to indicate the main vulnerabilities that the area is subjected. According to such diagnosis, some proposals for the establishment of Legal Reserves are discussed here based on scientific arguments aimed at the conservation of water resources, soil and biodiversity. It is hoped, that from this study, the environment receives a new tool for diagnosis, pollution control, recovery and conservation of natural resources.
