A integração entre o planejamento estratégico e o processo de elaboração orçamentária no setor público: o caso das organizações da Marinha

Para possibilitar o atendimento de demandas crescentes, e a cada dia mais complexas da sociedade, as organizações públicas necessitam utilizar ferramentas que permitam a condução de suas instituições a determinadas direções, buscando-se a melhoria dos serviços públicos e a redução do desperdício. Nesse cenário, o planejamento estratégico se mostra imprescindível, no entanto, não basta a sua formulação, esse tem que ser efetivamente implementado, permeando os demais processos da organização. Assim, este trabalho investigou a integração entre o planejamento estratégico e os sistemas gerenciais das organizações, em especial o orçamentário, que possui elevada relevância no setor público. O objetivo dessa pesquisa é identificar quais os fatores que influenciam a relação entre o planejamento estratégico e o processo de elaboração orçamentária nas organizações. Para tal, foi utilizada metodologia qualitativa, por meio de um estudo de caso múltiplo, que analisou quatro organizações da Marinha do Brasil. Os resultados da pesquisa permitiram o levantamento de diversos fatores, assim como os impactos causados por esses na relação estudada. No entanto, poucos fatores se apresentam da mesma forma nas organizações militares, havendo grande heterogeneidade não só entre as organizações, como também entre os setores de cada organização. Além disso, verifica-se que a implementação do planejamento estratégico, assim como de outras ferramentas administrativas que o fortalecem, encontra-se em plena evolução na Marinha, havendo tendência de fortalecimento do pensamento estratégico nessa Força nos próximos anos.

Política e burocracia do controle: as controladorias públicas nas capitais brasileiras

Investigar como as controladorias gerais municipais vêm se estruturando dentro do sistema político subnacional e identificar as similaridades e diferenças entre tais organizações são os principais objetivos deste trabalho. Tais atividades tornam-se relevantes a partir da constatação de que, apesar de ser cada vez mais frequente a alteração do nome e da estrutura do órgão central dos sistemas de controle interno subnacionais para controladorias gerais, não há uma regulamentação específica que predetermine os padrões institucionais, as funcionalidades organizacionais ou os escopos de atuação desses órgãos públicos. Cumpriu-se essa tarefa por meio das seguintes ações: (i) realização de pesquisa bibliográfica a partir da produção acadêmica dos cursos de pós-graduação em Administração Pública e Contabilidade (com ênfase no estudo de controladorias) no último triênio da CAPES (2010-2012); (ii) catalogação e análise dos instrumentos legais de institucionalização dos órgãos de controle interno nas capitais brasileiras; (iii) execução de análise organizacional comparada nas estruturas das controladorias-gerais encontradas. As pesquisas feitas constataram que a produção acadêmica da área de Administração Pública sobre o tema ainda é incipiente; que uma maior integração do campo técnico com diferentes campos acadêmicos (Administração Pública, Contabilidade, Ciência Política, Direito e Sociologia) se faz necessária; que, para além do processo de disseminação da esfera federal para local, há diversas bases estruturantes que influenciam o padrão adotado pelas controladorias públicas municipais; e que, enfim, não se pode falar em consolidação de um único formato institucional de controladoria mas, sim, de práticas constituídas conforme as diferentes conjunturas locais.

Turnaround de empresas com problemas de compliance - o caso Siemens

It is very relevant, for academic or for society purposes as a whole the subject "corruption", a recurring problem that plagues companies and Governments in various parts of the world. Many recent cases draw attention to this topic, but one in particular, the case of corruption of the company Siemens AG, that resulted in the payment of the largest fines in the history on your model, based on the terms of the FCPA since it became law in 1977. This event caters specifically to the objective of this work which is to make an analysis based on agency theory and the codes of good practices of corporate governance on how large companies revising their corporate management systems and practices aiming at the recovery of its institutional image after significant impact on the company, such as the corruption scandal in which Siemens was involved. For this study, we opted for qualitative research as a methodological path contemplating the single case study. In the process of data collection were used data obtained through documentary research about the corruption scandal on public collection available in the internet. Open conversations were made with 3 compliance Department officials of Siemens for the purposes of understanding the case with. At the end of this work, it was observed in the Siemens turnaround process a correlation between what was proposed by the Agency Theory about internal control Systems based on what was accomplished by the company when promoted an extensive restructuring of the Department of compliance and corporate governance system, the improvement of internal controls, as well as the creation of detection tools , control, analysis and prevention of fraud, which were used to minimize the effects generated by the conflict of interest covered by the theory of Agency. KEY WORDS: Corporate Governance; Compliance; Corruption; Turnaround, Agency Theory

Hudumia: a platform to support spontaneous volunteers' situational awareness, coordination and safety underemergency scenarios

Spontaneous volunteers always emerge under emergency scenarios and are vital to a successful community response, yet some uncertainty subsists around their role and its inherent acceptance by official entities under emergency scenarios. In our research we have identified that most of the spontaneous volunteers do have none or little support from official entities, hence they end up facing critical problems as situational awareness, safety instructions and guidance, motivation and group organization. We argue that official entities still play a crucial role and should change some of their behaviors regarding spontaneous volunteerism. We aim with this thesis to design a software architecture and a framework in order to implement a solution to support spontaneous volunteerism under emergency scenarios along with a set of guidelines for the design of open information management systems. Together with the collaboration from both citizens and emergency professionals we have been able to attain several important contributions, as the clear identification of the roles taken by both spontaneous volunteers and professionals, the importance of volunteerism in overall community response and the role which open collaborative information management systems have in the community volunteering efforts. These conclusions have directly supported the design guidelines of our software solution proposal. In what concerns to methodology, we first review literature on technologies support to emergencies and how spontaneous volunteers actually challenge these systems. Following, we have performed a field research where we have observed that the emerging of spontaneous volunteer’s efforts imposes new requirements for the design of such systems, which leaded to the creation of a cluster of design guidelines that supported our software solution proposal to address the volunteers’ requirements. Finally we have architected and developed an online open information management tool which has been evaluated via usability engineering methods, usability user tests and heuristic evaluations.

Projeto, construção e análise de um prototipo vibracional em escala de bancada aplicável ao tratamento de água de produção de petróleo bruto, mediante inovadora operação híbrida de adsorção e auto-flotação

A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

Épocas de consórcio de alho com cenoura em três sistemas de manejo de plantas daninhas, em Caçador-SC

O presente trabalho teve por objetivo avaliar os efeitos do consórcio alho e cenoura em quatro épocas de semeadura de cenoura e em três manejos de plantas daninhas, visando determinar os benefícios do consórcio em relação ao controle destas plantas, à produtividade, à rentabilidade e à sua qualidade comercial. Testaram-se quatro épocas de semeadura da cenoura (0, 15, 30 e 45 dias após o plantio do alho), combinadas a três manejos de plantas daninhas (com herbicida, sem controle e com capinas freqüentes). Utilizou-se o delineamento de blocos casualizados dispostos em parcelas subdivididas, com a época de semeadura da cenoura sendo parcela e o sistema de manejo, a sub-parcela, em quatro repetições. O oxadiazon a 750 g ha-1 não foi tóxico às plantas de alho nem às de cenoura. A rentabilidade do consórcio alho e cenoura foi vantajosa em relação ao monocultivo de alho, principalmente dentro do manejo com capinas freqüentes.

Contribuições à análise de robustez de sistemas de controle usando redes neurais

This work develops a robustness analysis with respect to the modeling errors, being applied to the strategies of indirect control using Artificial Neural Networks - ANN s, belong to the multilayer feedforward perceptron class with on-line training based on gradient method (backpropagation). The presented schemes are called Indirect Hybrid Control and Indirect Neural Control. They are presented two Robustness Theorems, being one for each proposed indirect control scheme, which allow the computation of the maximum steady-state control error that will occur due to the modeling error what is caused by the neural identifier, either for the closed loop configuration having a conventional controller - Indirect Hybrid Control, or for the closed loop configuration having a neural controller - Indirect Neural Control. Considering that the robustness analysis is restrict only to the steady-state plant behavior, this work also includes a stability analysis transcription that is suitable for multilayer perceptron class of ANN s trained with backpropagation algorithm, to assure the convergence and stability of the used neural systems. By other side, the boundness of the initial transient behavior is assured by the assumption that the plant is BIBO (Bounded Input, Bounded Output) stable. The Robustness Theorems were tested on the proposed indirect control strategies, while applied to regulation control of simulated examples using nonlinear plants, and its results are presented

Estrutura ANFIS modificada para identificação e controle de plantas com ampla faixa de operação e não linearidade acentuada

In this work a modification on ANFIS (Adaptive Network Based Fuzzy Inference System) structure is proposed to find a systematic method for nonlinear plants, with large operational range, identification and control, using linear local systems: models and controllers. This method is based on multiple model approach. This way, linear local models are obtained and then those models are combined by the proposed neurofuzzy structure. A metric that allows a satisfactory combination of those models is obtained after the structure training. It results on plant s global identification. A controller is projected for each local model. The global control is obtained by mixing local controllers signals. This is done by the modified ANFIS. The modification on ANFIS architecture allows the two neurofuzzy structures knowledge sharing. So the same metric obtained to combine models can be used to combine controllers. Two cases study are used to validate the new ANFIS structure. The knowledge sharing is evaluated in the second case study. It shows that just one modified ANFIS structure is necessary to combine linear models to identify, a nonlinear plant, and combine linear controllers to control this plant. The proposed method allows the usage of any identification and control techniques for local models and local controllers obtaining. It also reduces the complexity of ANFIS usage for identification and control. This work has prioritized simpler techniques for the identification and control systems to simplify the use of the method

Uma abordagem indireta para o Controlador em Modo Dual Adaptativo Robusto

In this work is proposed an indirect approach to the DualMode Adaptive Robust Controller (DMARC), combining the typicals transient and robustness properties of Variable Structure Systems, more specifically of Variable Structure Model Reference Adaptive Controller (VS-MRAC), with a smooth control signal in steady-state, typical of conventional Adaptive Controllers, as Model Reference Adaptive Controller (MRAC). The goal is to provide a more intuitive controller design, based on physical plant parameters, as resistances, inertia moments, capacitances, etc. Furthermore, with the objective to follow the evolutionary line of direct controllers, it will be proposed an indirect version for the Binary Model Reference Adaptive Controller (B-MRAC), that was the first controller attemptting to act as MRAC as well as VS-MRAC, depending on a pre-defined fixed parameter

Estudo e implementação em plantas físicas de um controlador preditivo generalizado com restrições

This work shows a study about the Generalized Predictive Controllers with Restrictions and their implementation in physical plants. Three types of restrictions will be discussed: restrictions in the variation rate of the signal control, restrictions in the amplitude of the signal control and restrictions in the amplitude of the Out signal (plant response). At the predictive control, the control law is obtained by the minimization of an objective function. To consider the restrictions, this minimization of the objective function is done by the use of a method to solve optimizing problems with restrictions. The chosen method was the Rosen Algorithm (based on the Gradient-projection). The physical plants in this study are two didactical systems of water level control. The first order one (a simple tank) and another of second order, which is formed by two tanks connected in cascade. The codes are implemented in C++ language and the communication with the system to be done through using a data acquisition panel offered by the system producer

Desenvolvimento de um middleware para comunicação via web services e sua aplicação em sistemas de aquisição de dados industriais

The control of industrial processes has become increasingly complex due to variety of factory devices, quality requirement and market competition. Such complexity requires a large amount of data to be treated by the three levels of process control: field devices, control systems and management softwares. To use data effectively in each one of these levels is extremely important to industry. Many of today s industrial computer systems consist of distributed software systems written in a wide variety of programming languages and developed for specific platforms, so, even more companies apply a significant investment to maintain or even re-write their systems for different platforms. Furthermore, it is rare that a software system works in complete isolation. In industrial automation is common that, software had to interact with other systems on different machines and even written in different languages. Thus, interoperability is not just a long-term challenge, but also a current context requirement of industrial software production. This work aims to propose a middleware solution for communication over web service and presents an user case applying the solution developed to an integrated system for industrial data capture , allowing such data to be available simplified and platformindependent across the network

Método não destrutivo de estimativa da área foliar de plantas daninhas de ambiente aquático: tanner-grass e capim-fino

The continuous inputs from agriculture areas and human or industrial sewer have been provided a widely demographic explosion of tropical tanner-grass and para grasss plants in the rivers and water reservoirs of Brazil. Considering the importance of these noxious weeds there is a vast necessity of basic studies on aspects related to reproduction, growing, development, nutritional requirements, responses to control systems and others. In most studies, leaf area knowledge is crucial and it is one of the most difficult characteristics to be measured because it usually requires expensive equipments or it uses a destructive technique. The objective of this work was to develop equations for leaf blade dimensional parameters to allow determination of the leaf area of African tanner-grass (Brachiaria subquadripara (Trin.) Hitchc) and para grass (Brachiaria mutica (Forsk.) Stapf.). Correlations between real leaf area and dimensional parameters of leaf blade such as length along the main vein (L) and maximum width (W) perpendicular to the main axis were studied. Only the linear equations allowed a good leaf area estimate. It is suggested to opt for a simple linear equation involving respective products of length times maximum width considering linear coefficient equal to zero. Thus, B. subquadripara (SS) and B. mutica (SM) non destructive leaf blade area estimates may be performed by the following formulas: SS = 0.7719 (L x W) and SM = 0.7479 (L x W), with coefficients of determination (R(2)) of 0.9594 and 0.9408, respectively.
