Objetivo: Avaliar a efetividade de uma t?cnica simplificada (S) para confec??o de pr?tese total, comparando-a a tradicional (T), atrav?s da efici?ncia mastigat?ria e da avalia??o da qualidade das pr?teses. M?todo: Realizou-se um ensaio cl?nico controlado randomizado com 50 pacientes, 25 reabilitados com pr?teses totais duplas produzidas pela t?cnica tradicional e 25 reabilitados por uma t?cnica simplificada. Avaliou-se a efici?ncia mastigat?ria pelo m?todo colorim?trico com o aux?lio de uma c?psula mastigat?ria. A qualidade das pr?teses foi obtida por meio do instrumento desenvolvido por Sato et al. em 1998. Resultados: 39 pacientes conclu?ram o estudo, sendo 18 do grupo tradicional e 21 do grupo simplificado. N?o houve diferen?a entre os grupos para a efici?ncia mastigat?ria (p=0.835). Um paciente apresentou pr?tese com qualidade ruim (grupo S), nove com qualidade regular (T= 3; S=6) e 29 pacientes apresentaram pr?teses com qualidade boa (T= 15; S= 14), sem diferen?as entre os grupos. A qualidade das pr?teses obteve diferen?a significativa para a atura do rebordo inferior (p=0.05). Conclus?o: as pr?teses totais duplas confeccionadas pelo m?todo simplificado foram consideradas eficazes do ponto de vista da efici?ncia mastigat?ria e da qualidade das pr?teses, apresentando resultados semelhantes ?s confeccionadas pelo m?todo tradicional. / Traditional methods for dentures fabrication require a wide clinical and laboratory procedures; however, there is no scientific evidence that these methods can produce better results when compared with simplified methods. Aim: To evaluate the effectiveness of a simplified methods for denture fabrication, comparing it to the traditional one through masticatory efficiency and prosthesis quality. Method: A randomized controlled trial was conducted with 50 patients, 25 rehabilitated with prosthesis produced by traditional technique and 25 rehabilitated by a simplified technique. The masticatory efficiency was evaluated by colorimetric method, using chewing capsules. The quality of prosthesis was obtained using a reliable and reproducible instrument. Statistical analysis of the masticatory efficiency and quality of the prosthesis was obtained by the Mann-Whitney test. Results: 39 patients completed the study, 18 on traditional group and 21 on simplified group. There was no difference between groups for the masticatory efficiency (p = 0.835) and the quality of the prosthesis (p = 0672). The evaluation of the overall quality of the prosthesis according to oral conditions, demonstrated significant difference on the height of the mandibular ridges (p = 0.010) and mandibular muscle attachments (p = 0.039). Conclusion: Complete dentures fabricated by simplified method were considered effective from the point of view of masticatory efficiency and quality of prosthetics, with results similar to those made by the traditional method.

Estudos mostram que a fra??o Acetato de Etila (AcOEt) obtida a partir do extrato acetona das cascas do caule de A. occidentale apresenta atividade anti-inflamat?ria, sugerindo-se os taninos como respons?veis por essa a??o. Sendo uma das 71 esp?cies da Rela??o Nacional de Plantas Medicinais de Interesse ao Sistema ?nico de Sa?de (RENISUS), ? importante que sejam desenvolvidas metodologias anal?ticas para o estudo dos seus constituintes. Nesse contexto, a Cromatografia L?quida de Alta Efici?ncia (CLAE) constitui uma metodologia de import?ncia para a an?lise de amostras de origem vegetal. Este estudo teve como objetivo desenvolver e validar uma metodologia anal?tica por CLAE para a an?lise da fra??o AcOEt do extrato acetona das cascas do caule de A. occidentale. As condi??es cromatogr?ficas foram estabelecidas utilizando como fase m?vel ?cido ac?tico a 0,3% e acetonitrila. Como ponto de partida para o desenvolvimento do m?todo cromatogr?fico, foi utilizado um gradiente explorat?rio, que permite analisar todas as faixas de polaridade. O gradiente de elui??o foi ent?o ajustado at? a obten??o de um cromatograma com adequada separa??o e par?metros cromatogr?ficos satisfat?rios. Para a identifica??o dos compostos, foi realizada a an?lise de padr?es e, pela observa??o dos tempos de reten??o e espectros de absor??o das subst?ncias, foi poss?vel eleger as que estariam presentes na amostra. Foi poss?vel sugerir a presen?a de catequina, epicatequina, epigalocatequina e ?cido g?lico na fra??o AcOEt de A. occidentale. Para a valida??o do m?todo, foram realizados os testes de linearidade, precis?o, exatid?o, robustez, limites de detec??o e quantifica??o. O m?todo foi avaliado como sendo linear, preciso e exato para os compostos estudados. Dentre as condi??es de an?lise alteradas para o estudo da robustez, o m?todo n?o apresentou robustez para a an?lise do ?cido g?lico, quando a temperatura da coluna foi de 35?C, mas as demais condi??es alteradas n?o promoveram mudan?as estatisticamente significativas para este analito. Conclui-se que o m?todo cromatogr?fico ? adequado para a an?lise da fra??o AcOEt do extrato acetona de A. occidentale. / Anacardium occidentale Linn is a tree native to Brazil, popularly known as cashew. Studies show that the Ethyl Acetate fraction (EtOAc) obtained from the acetone:water extract of the A. occidentale stem bark has anti-inflammatory activity, suggesting tannins as responsible for this action. As one of 71 species of the National List of Medicinal Plants of Interest to the Unified Health System (RENISUS), it is important that analytical methodologies for the study of its constituents are developed. In this context, the High Performance Liquid Chromatography (HPLC) is a method of importance to the analysis of samples of plant origin. This study aimed to develop and validate an analytical methodology by HPLC for analysis of EtOAc fraction of acetone:water extract from the stem bark of A. occidentale. The chromatographic conditions were established using acetic acid 0.3% (v/v in water) and acetonitrile as the mobile phase. As a starting point for the development of chromatographic procedures, exploratory gradient was used, which allows to analyze all polarity groups. The gradient elution was then adjusted to obtain a chromatogram with adequate separation and satisfactory chromatographic parameters. For identification of the compounds, the pattern analysis was carried out, and by observing the retention times and absorption spectra of the substances was possible to choose those which would be present in the sample. It could suggest the presence of catechin, epicatechin, epigallocatechin and gallic acid in the EtOAc fraction of A. occidentale. To validate the method, linearity tests were performed, precision, accuracy, robustness, limits of detection and quantification. According to Resolution 899/2003 (ANVISA), the method was assessed to be linear, precise and accurate for the studied compounds. Among the changed analysis conditions for studying the robustness of the method, when the column temperature was 35?C analysis did not present robustness for gallic acid, but when other conditions were changed it did not promote statistically significant changes to this analyte. It follows that the chromatographic method is suitable for analysis of gallic acid, catechin and epicatechin in EtOAc fraction of the acetone:water extract of the A. occidentale.

Contudo, a Aneel aplica as pol?ticas de tarifa??o separadamente entre os segmentos que comp?em o sistema el?trico, n?o considerando as rela??es existentes na cadeia de suprimentos. O presente trabalho tem como objetivo propor um novo modelo de an?lise de efici?ncia do sistema el?trico brasileiro a fim de tornar a revis?o tarif?ria melhor ajustada para a realidade do cen?rio atual. Os segmentos do setor (gera??o, transmiss?o e distribui??o) foram fundamentados por meio de um conjunto de vari?veis recorrentes na literatura para retratar os processos realizados no sistema el?trico, no ?mbito nacional e internacional. A partir disso, o modelo conceitual considera 12 vari?veis distribu?das em tr?s dimens?es: custo, produtividade e qualidade. A amostra contempla 94 empresas, dentre as quais segmentam: 16 empresas de gera??o, 28 empresas transmissoras de energia e 50 empresas distribuidoras. As Unidades Tomadoras de Decis?o (Decision Making Units - DMU) foram classificadas como os caminhos com as diferentes empresas da gera??o at? a distribui??o de energia, de forma que a amostra totalizou em 362 DMUs. Na condu??o da pesquisa, elaborou-se um modelo para avalia??o do sistema el?trico com a utiliza??o da An?lise Envolt?ria de Dados (DEA ? Data Envelopment Analysis), com o prop?sito de identificar quantitativamente o n?vel de efici?ncia da rede. De modo a poder representar a complexidade do sistema el?trico, o modelo proposto utiliza o DEA em redes (Network Data Envelopment Analysis ? NDEA) com tr?s est?gios, cada um simulando os segmentos do setor, para identificar os impactos entre os processos e as causas de inefici?ncia. Esses est?gios da rede foram avaliados para verificar a performance das empresas em cada segmento e validar o modelo de retornos constantes de escala, por meio dos modelos cl?ssicos CCR em compara??o com o NDRS, utilizado pela Aneel. A partir dessa compara??o entre os modelos cl?ssicos, validou-se o uso do modelo de retornos constantes de escala para as an?lises do setor. Os resultados do modelo NDEA apontam para a adequa??o do m?todo proposto realizando a an?lise agregada do sistema el?trico, ao apresentar resultados mais discriminat?rios que os modelos cl?ssicos. Obteve-se que nenhum caminho da rede observado possui as tr?s empresas constituintes eficientes em sua totalidade. Contudo, foi poss?vel identificar em quais liga??es as empresas devem focar seus investimentos para alcan?ar melhores desempenhos e quais redes ter como benchmarks, contribuindo para a tomada de decis?o gerencial e o planejamento eficiente das empresas. Por fim, identificou-se os fatores ex?genos que influenciam na efici?ncia, como a regi?o geogr?fica e porte, sendo poss?vel ent?o, obter diagn?sticos para uma tarifa??o mais adequada ? realidade do setor, beneficiando tanto os consumidores, quanto as empresas e o governo. / The Brazilian electricity sector has shown different changes, since unbundling of companies to the creation of the regulatory agency (Aneel - National Electric Energy Agency), responsible for the economic regulation of the transmission and distribution segments. However, Aneel applies charging policies separately between the segments that make up the electrical system, not considering the relationship in the supply chain. In this context, this paper aims to propose a new model of the Brazilian electric system efficiency analysis in order to make the best-adjusted tariff review with the system reality. The segments of the industry (generation, transmission and distribution) were founded through a set of recurring variables in the literature to portray the processes carried out in the electrical system at the national and international levels. The conceptual model includes initially 12 variables divided into three dimensions: cost, productivity and quality. The sample includes 94 companies, consisting of in 16 generation companies, 28 electricity transmission companies and 50 distribution companies. The Decision Making Units (DMU) were considered the paths from generation to distribution, so that the sample contains 362 DMUs in total. In conducting the research analysis, a model was developed to evaluate the electrical system using the data envelopment analysis (DEA) to quantitatively identify the network efficiency level. To be able to represent the complexity of the electrical system, a unique grouping model was proposed and analyzed by Network DEA's model (NDEA) in three stages, each one simulating a particular segment of the industry, in order to identify the impacts between the processes and the causes of inefficiency. These stages of the network were evaluated to verify the performance of the companies in each segment and validate the model of constant returns to scale, through the classic models CCR compared to the NDRS used by Aneel. From this comparison between the classic models, the use of constant returns to scale model for sector analysis was validated. The results of the NDEA model point to the adequacy of the proposed method by performing the electrical system aggregate analysis, by presenting more discriminatory results than classic models. Furthermore, none of the paths have efficient companies in all of its three stages. However, it was possible to identify which links those companies should focus their investments to achieve better performance and which networks are its benchmarks, contributing to the decision-making and the efficient planning of companies. Finally, we identified the exogenous factors that influence efficiency, such as geography and size, thereby making possible to obtain a more appropriate tariffing regarding the reality of the sector, benefiting consumers, companies and the government.

A amostra ? constitu?da por um painel de dados balanceado com informa??es referentes a 56 munic?pios do Estado do Rio Grande do Norte para o per?odo 2009-2011. Inicialmente, busca-se avaliar a efici?ncia municipal do gasto p?blico por meio da modelagem cl?ssica DEA-CCR. Em seguida, realiza-se o c?lculo da efici?ncia relativa dos munic?pios potiguares por meio do modelo NDEA, no qual s?o considerados quatro est?gios de an?lise, dois para cada dimens?o. A utiliza??o da abordagem de redes possibilita tanto avaliar a produtividade relativa das unidades operacionais em cada um dos sub-processos produtivos quanto permite estimar a efici?ncia global do sistema. O primeiro e terceiro est?gios consistem na execu??o or?ament?ria para contrata??o de recursos alocados no setor de educa??o e sa?de, respectivamente.

Os resultados obtidos no estudo empreendido indicam que a expans?o dos gastos municipais destinados a presta??o de servi?os p?blicos de educa??o e sa?de no Estado do Rio Grande do Norte n?o garantiu a amplia??o do acesso da popula??o a tais servi?os e, simultaneamente, n?o promoveu melhorias na qualidade dos outputs associados a essas dimens?es ao longo do tempo. Assim, torna-se urgente que os governos dos munic?pios mais ineficientes, quanto ? execu??o or?ament?ria nas dimens?es de educa??o e sa?de infantil, realizem uma avalia??o da estrutura interna destes setores a fim de identificar eventuais fontes de inefici?ncia e de forma emergencial, no curto prazo, espelhem-se nos munic?pios que apresentam os melhores ?ndices de produtividade relativa. / The objective of this study is to evaluate the efficiency of the municipalities of Rio Grande do Norte by applying public resources destined to the education and child health sector, considering both productive subprocesses and intertemporal aspects in research. In order to meet these objectives, the research method proposes a quantitative approach based on the use of the Data Envelopment Analysis with the use of Network Data Envelopment Analysis ? NDEA and Dynamic Data Envelopment Analysis ? DDEA. The sample consists of a balanced data panel with information referring to 56 municipalities of the State of Rio Grande do Norte for the 2009-2011 period. Initially, the aim is to evaluate the municipal efficiency of public spending through the classical DEA-CCR modeling. Then, the calculation of the relative efficiency of the municipalities of Potiguares is carried out by means of the NDEA model, in which four stages of analysis are considered, two for each dimension. The use of the network approach makes it possible both to evaluate the relative productivity of the operating units in each of the productive subprocesses and to estimate the overall efficiency of the system. The first and third stages consist of budget execution for contracting of resources allocated in the education and health sector, respectively. The second and fourth stages, in turn, use the resources contracted to promote the effectiveness of teaching and health. Finally, the DDEA model is applied in order to estimate the intertemporal dynamic effects associated with the analyzed dimensions. The results obtained in the study carried out indicate that the expansion of municipal expenditures for the provision of public health and education services in the State of Rio Grande do Norte did not guarantee the expansion of the population's access to such services and, at the same time, did not promote improvements in quality Of the outputs associated with these dimensions over time. Thus, it is urgent that the most inefficient municipal governments, regarding budgetary execution in the dimensions of education and child health, carry out an evaluation of the internal structure of these sectors in order to identify possible sources of inefficiency and in an emergency in the short term, Are reflected in the municipalities that present the best relative productivity indexes.

However, since that time, doctrine and majority jurisprudence do not admit an objective public liability when the damage occurs due to a negative behavior of the Public Administration. Based on the article 15 of the Civil Code of 1916, they affirm that public liability for omission should be read subjectively, through the French theory of faute de service, whose responsibility is given when the service has not worked, or has functioned in a deficient way, or inopportunely, even admitting the anonymous fault of the Public Administration. Nevertheless, considering the constitutional maintenance of objective public liability and the validity of the Civil Code of 2002, whose rule of attribution of the liability of the State says it is objective, through a hypothetical-deductive analysis of national and foreign doctrine and jurisprudence, it was perceived that resistance to the objectification of public liability also occurs, in cases of administrative omissions, due to ideological and non-theoretical reasons, because (i) the faute de service, even in France, has its reading objectified, (ii) the investigated national jurisprudence, when judging damaging positive state behavior, motivates its judgments into the malfunctioning of the public service, not revealing that it is applying the theory of faute de service, (iii) this same jurisprudence, when analyzing administrative omissions, does it through objective criteria, and (iv) the Constitution does not make any distinction of factors of attribution of public liability. For this reason, it is concluded that rather than transplanting an alien institute, it is possible to assert a public liability for omissions in an objective way, giving the essential prevalence to the causal nexus, through the appropriate causality theory, allowing a retrospective judgment of probability, under the lights of the informative principles of Public Administration, especially those of reasonableness and efficiency, in the implementation of good public administration, the inherent obligation of the public authorities to promote the fundamental rights of people, fostering their dignity in a way that administrative actions harmonize criteria of objectivity, impartiality, justice and equity, which are provided within reasonable time, making possible the free and solidary development of each person in their society. Reasonableness requires the existence of a certain equivalence relation between the adopted measure and criteria that dimensions it, connecting the searched purpose to the means to be used with the examination of this adequacy in abstract, general and antecedent way. The efficiency in offering the concrete utilities to the citizen, in the combination of equity and efficiency of the public service, through a concerted, encouraging and negotiated action in the realization of fundamental rights. / La responsabilit? civile non contractuelle de l?Administration Publique br?silienne est inform? par dispositif l?gal qui lui attribue caract?re objectif, dans laquelle les personne morale de droit public interne sont civilement responsables pour les dommages que ses fonctionnaires, dans cette qualit?, causent ? tiers. Toutefois, depuis ce temps, la doctrine et la jurisprudence majoritaire n?admettent pas une responsabilit? publique objective lorsque les dommages surviennent par le comportement n?gatif de l?Administration Publique. Sous l?article 15 du Code Civil de 1916, ils pr?tendent que la responsabilit? publique par omission doit ?tre lue de mani?re subjective, par la th?orie fran?aise de la faute de service, dont la responsabilit? est occasionn?e quand le service n?a pas fonctionn? ou a fonctionn? de mani?re d?ficiente, ou intempestivement, en admettant m?me la culpabilit? anonyme de l?Administration Publique. N?anmoins, en ayant vue du maintien constitutionnel de la responsabilit? publique objective et de la validit? du Code Civil de 2002, dont la r?gle d?imputation de la responsabilit? de l??tat lui dit objectif, par une analyse hypoth?tiqued?ductive de la doctrine et de la jurisprudence nationales et ?trangers, il a ?t? constat? que la r?sistance ? l?objectivation de la responsabilit? publique aussi occasionne, en cas d?omissions administratives, par questions id?ologiques et non th?oriques, parce que (I) la faute de service, m?me en France, a sa lecture objective, (II) la jurisprudence national recherch?, lorsque le jugement des comportements ?tatique positifs nuisibles, motive ses jugements dans le dysfonctionnement du service public, sans dire qu?il applique la th?orie de faute de service, (III) cette m?me jurisprudence, lors de l?analyse des omissions administratives, elle fait avec des crit?res objectifs, et (IV) la Constitution ne fait pas la distinction entre les facteurs d?attribution de la responsabilit? publique. Pour cette raison, il est conclu que, mieux que la transplantation d?un institut ?tranger, il est possible d?affirmer une responsabilit? publique pour les omissions d?une mani?re objective, en donnant la pr?valence essentielle au lien de causalit?, par la th?orie de causalit? appropri?e, permettant une jugement r?trospectif de probabilit?, sous la lumi?re des principes informateurs de l?Administration Publique, en particulier ceux du caract?re raisonnable et de l?efficience, dans la r?alisation d?une bonne administration publique, obligation inh?rente aux pouvoirs publics de promouvoir les droits fondamentaux de personnes, en favorisant leur dignit? de telle sorte que les actions administratives harmonisent les crit?res d?objectivit?, d?impartialit?, de justice et d??quit?, et qui sont rendus dans un d?lai raisonnable, permettant le d?veloppement libre et solidaire de chaque personne dans sa soci?t?. Le caract?re raisonnable exige l?existence d?un certain relation d??quivalence entre la mesure adopt?e et le crit?re qui l??chelle, en donnant le lien de la fin qui est demand?e et les moyens qu?elle utilise avec l?examen de cette ad?quation sous une forme abstraite, g?n?rale et ant?c?dente. L?efficacit? de l?offre de services publics concrets au citoyen, conjointement avec l??quit? et l?efficience de la fonction publique, par le biais de concertation, de promotion, de n?gociation, dans la r?alisation des droits fondamentaux. / A responsabilidade civil extracontratual da Administra??o P?blica brasileira ? informada por dispositivo legal que lhe atribui natureza objetiva, onde as pessoas jur?dicas de direito p?blico interno s?o civilmente respons?veis pelos danos que os seus funcion?rios, nessa qualidade, causem a terceiros. Contudo, desde aquela ?poca, a doutrina e jurisprud?ncia majorit?ria n?o admitem uma responsabilidade p?blica objetiva quando o dano ocorre por um comportamento negativo da Administra??o P?blica. Sob o fundamento do artigo 15 do C?digo Civil de 1916, afirmam que a responsabilidade p?blica por omiss?o deve ser lida de forma subjetiva, mediante a teoria francesa da faute de service, cuja responsabilidade d?-se quando o servi?o n?o funcionou, ou funcionou de forma deficiente, ou intempestivamente, admitindo-se inclusive a culpa an?nima da Administra??o P?blica. N?o obstante, tendo em vista a manten?a constitucional da responsabilidade p?blica objetiva e a vig?ncia do C?digo Civil de 2002, cuja regra de imputa??o da responsabilidade do Estado a diz objetiva, mediante an?lise hipot?tico-dedutiva da doutrina e jurisprud?ncia nacional e estrangeira, percebeu-se que a resist?ncia ? objetiva??o da responsabilidade p?blica tamb?m ocorre, nos casos de omiss?es administrativas, por quest?es ideol?gicas e n?o te?ricas, pois (i) a faute de service, inclusive na Fran?a, tem sua leitura objetivada, (ii) a jurisprud?ncia nacional pesquisada, quando do julgamento de comportamentos estatais positivos danosos, motiva seus ac?rd?os no mau funcionamento do servi?o p?blico, sem dizer que est? aplicando a teoria da faute de service, (iii) essa mesma jurisprud?ncia, quando analisa as omiss?es administrativas, o faz mediante crit?rios objetivos, e (iv) a Constitui??o n?o faz qualquer distin??o de fatores de atribui??o da responsabilidade p?blica. Por essa raz?o, conclui-se que, melhor do que transplantar um instituto alien?gena, ? poss?vel afirmar uma responsabilidade p?blica por omiss?es de forma objetiva, dando a preval?ncia imprescind?vel ao nexo causal, por interm?dio da teoria da causalidade adequada, permitindo um ju?zo retrospectivo de probabilidade, sob as luzes dos princ?pios informadores da Administra??o P?blica, em especial os da razoabilidade e efici?ncia, na concretiza??o da boa administra??o p?blica, obriga??o inerente aos poderes p?blicos de promover os direitos fundamentais das pessoas, fomentando sua dignidade de forma que as atua??es administrativas harmonizem crit?rios de objetividade, imparcialidade, justi?a e equidade, e que sejam prestadas em prazos razo?veis, possibilitando o livre e solid?rio desenvolvimento de cada pessoa em sua sociedade. A razoabilidade exige a exist?ncia de determinada rela??o de equival?ncia entre a medida adotada e o crit?rio que a dimensiona, conferindo a liga??o do fim que se busca e do meio que se utiliza com o exame desta adequa??o de forma abstrata, geral e antecedente. A efici?ncia no oferecimento das utilidades concretas ao cidad?o, na conjuga??o de equidade e efici?ncia do servi?o p?blico, mediante uma atua??o concertada, fomentadora, negociada, na concretiza??o dos direitos fundamentais.

The results have shown that competence derives mainly from the individual's fundamental characteristics, their upbringing (knowledge, ability, attitude), behavior and action towards work. What is more, it has indicated that young managers, MBA/specialization graduates, consider eleven faculties, mainly behavioral ones, as the most efficient: initiative, personal as well as team development and confidence on decision making. The motivation of this research comes from the necessity of professionals to develop faculties that distinguish them from one another, and also of showing, through the accomplishment of a task, the capacity to promote future changes that will support the organization when facing its competitors. This comes as a response to the rapid development of technology, globalization, the growth of new and varied organizations and the new standard of fierce competition, which results in environmental changes and uncertainties never seen before. However, the whole dynamics make the traditional sources of competitive advantages obsolete, overcome by innovation, and rely on the individual's ability to adapt and learn faster. / Esta pesquisa foi realizada atrav??s de uma abordagem explorat??ria, quantitativa com utiliza????o de dados prim??rios junto a uma amostra conveniente de gestores de empresas da Grande S??o Paulo e fundamentada nas teorias de compet??ncia. Os resultados demonstraram que a compet??ncia decorre principalmente das caracter??sticas subjacentes dos indiv??duos, da forma????o (conhecimento, habilidade, atitude), comportamento e a????o diante do trabalho. E que gestores jovens, graduados com MBA/especializa????o percebem onze compet??ncias como as mais eficazes, sendo as principais relacionadas ao comportamento, tais como: iniciativa, desenvolvimento de pessoas e equipes e confian??a na tomada de decis??o, as que mais se destacaram. A motiva????o dessa pesquisa deu-se da necessidade dos profissionais desenvolverem compet??ncias que os distinguem, como tamb??m, de mostrar, atrav??s do desempenho de um trabalho, a capacidade de prover as mudan??as do futuro que sustentem a organiza????o frente aos concorrentes. Isso decorre do desenvolvimento r??pido das tecnologias, globaliza????o, o crescimento de novas e diferenciadas organiza????es e do novo padr??o de competi????o intenso, que cria mudan??as ambientais e incertezas jamais vistas. No entanto, toda essa din??mica, faz com que as fontes tradicionais de vantagens competitivas se tornem obsoletas ou superadas pela pr??pria inova????o, estando na habilidade individual a capacidade de adaptar e aprender mais rapidamente.

This study is motivated by this perspective. The aim is to analyze the motivational factors for the practice of earnings management in Brazilian listed companies. For this, a survey was conducted with data from listed companies in the capital markets in Brazil. The sample consisted of 1,209 company-year in the period 2007-2012. A factor analysis was performed in order to better explain the motivational factors and also analysis using multiple regression models. The results of the statistical tests showed, in general, that the better the corporate governance mechanisms adopted by companies, the less motivation to practice earnings management. Among the internal mechanisms stood out in a positive way to inhibit the practice of earnings management, the independence and competence of the board, and externally the actions of regulatory agencies. Contrary to previous literature, the results indicated that the concentration of control inhibit the practice of earnings management, while more rights to investors motivate this practice, which may be explained by characteristics of the sample of Brazilian firms as family or state control, weak reliance on the stock market, among others / O Brasil desenvolveu seu mercado de capitais na ??ltima d??cada, apesar de ainda apresentar um alto n??vel de percep????o de corrup????o e burocracia, risco, fatores inibidores dos investimentos internos e externos nos mercados de capitais. O presente estudo ?? motivado por essa perspectiva. O objetivo desta pesquisa ?? analisar os fatores motivacionais para a pr??tica de gerenciamento de resultados em empresas brasileiras de capital aberto. Para isso, foi realizada uma pesquisa com dados de empresas listadas nos mercados de capitais do Brasil. A amostra consistiu em 1.209 empresas-ano, no per??odo de 2007 a 2012. Foi efetuada uma an??lise fatorial de forma a explicar melhor os fatores motivacionais e tamb??m foi realizada uma an??lise por modelos de regress??o m??ltipla. Os resultados dos testes estat??sticos indicaram, de maneira geral, que quanto melhores os mecanismos de governan??a corporativa adotados pelas empresas, menor a motiva????o para a pr??tica de gerenciamento de resultados. Dentre os mecanismos internos destacaram-se de forma positiva para inibir as pr??ticas de gerenciamento de resultados, a independ??ncia e compet??ncia do conselho de administra????o e, externamente, as a????es dos ??rg??os regulat??rios. Contrariando a literatura anterior, os resultados indicaram que a concentra????o de controle inibiria a pr??tica de gerenciamento de resultados, enquanto maiores direitos aos investidores motivariam esta pr??tica, o que pode ser explicado por caracter??sticas pr??prias de empresas brasileiras da amostra como controle familiar ou estatal, fraca depend??ncia de recursos do mercado acion??rio, entre outros
