Visualization of spirography-based objective measures in Parkinson's disease

Objective: To investigate whether advanced visualizations of spirography-based objective measures are useful in differentiating drug-related motor dysfunctions between Off and dyskinesia in Parkinson’s disease (PD). Background: During the course of a 3 year longitudinal clinical study, in total 65 patients (43 males and 22 females with mean age of 65) with advanced PD and 10 healthy elderly (HE) subjects (5 males and 5 females with mean age of 61) were assessed. Both patients and HE subjects performed repeated and time-stamped assessments of their objective health indicators using a test battery implemented on a telemetry touch screen handheld computer, in their home environment settings. Among other tasks, the subjects were asked to trace a pre-drawn Archimedes spiral using the dominant hand and repeat the test three times per test occasion. Methods: A web-based framework was developed to enable a visual exploration of relevant spirography-based kinematic features by clinicians so they can in turn evaluate the motor states of the patients i.e. Off and dyskinesia. The system uses different visualization techniques such as time series plots, animation, and interaction and organizes them into different views to aid clinicians in measuring spatial and time-dependent irregularities that could be associated with the motor states. Along with the animation view, the system displays two time series plots for representing drawing speed (blue line) and displacement from ideal trajectory (orange line). The views are coordinated and linked i.e. user interactions in one of the views will be reflected in other views. For instance, when the user points in one of the pixels in the spiral view, the circle size of the underlying pixel increases and a vertical line appears in the time series views to depict the corresponding position. In addition, in order to enable clinicians to observe erratic movements more clearly and thus improve the detection of irregularities, the system displays a color-map which gives an idea of the longevity of the spirography task. Figure 2 shows single randomly selected spirals drawn by a: A) patient who experienced dyskinesias, B) HE subject, and C) patient in Off state. Results: According to a domain expert (DN), the spirals drawn in the Off and dyskinesia motor states are characterized by different spatial and time features. For instance, the spiral shown in Fig. 2A was drawn by a patient who showed symptoms of dyskinesia; the drawing speed was relatively high (cf. blue-colored time series plot and the short timestamp scale in the x axis) and the spatial displacement was high (cf. orange-colored time series plot) associated with smooth deviations as a result of uncontrollable movements. The patient also exhibited low amount of hesitation which could be reflected both in the animation of the spiral as well as time series plots. In contrast, the patient who was in the Off state exhibited different kinematic features, as shown in Fig. 2C. In the case of spirals drawn by a HE subject, there was a great precision during the drawing process as well as unchanging levels of time-dependent features over the test trial, as seen in Fig. 2B. Conclusions: Visualizing spirography-based objective measures enables identification of trends and patterns of drug-related motor dysfunctions at the patient’s individual level. Dynamic access of visualized motor tests may be useful during the evaluation of drug-related complications such as under- and over-medications, providing decision support to clinicians during evaluation of treatment effects as well as improve the quality of life of patients and their caregivers. In future, we plan to evaluate the proposed approach by assessing within- and between-clinician variability in ratings in order to determine its actual usefulness and then use these ratings as target outcomes in supervised machine learning, similarly as it was previously done in the study performed by Memedi et al. (2013).

Reelection incentives and political corruption : evidence from Brazil’s municipal audit reports

This paper uses a unique dataset of political corruption, constructed from municipal audit reports obtained from Brazil’s randomized anti-corruption program, to test whether reelection incentives affect the level of rent extraction of incumbent politicians. In order to identify reelection incentives, we use the existence of a term limit in Brazil’s municipal elections. We find that in municipalities where mayors are in their second and final term, there is significantly more corruption compared to similar municipalities where mayors are in their first-term. In particular, in municipalities with second-term mayors there is, on average, R$188,431 more diversion of resources and the incidence of irregularities is 23% higher. We also find more pronounced effects where the costs of rent-extraction are lower (municipalities without media and judicial presence), and the density of pivotal voters is higher (more political competition). Finally, we show that first-term mayors, while less corrupt, have a larger incidence of poor administration suggesting that there may exist a trade-off between corruption and quality in public good provision.

Equipes de trabalho na administração municipal: a captação de recursos para o desenvolvimento no município de Natividade/RJ

This thesis aims to identify how teams of at job municipality Natividade influence in raising funds through projects. Was employed research descriptive, explanatory literature and content analysis focused on a qualitative approach, which led to the interpretation of elements detected in field research, aligning them with researched theoretical material . The survey results indicate that the municipal administrators in their departments work of non-integrated form, complicating and compromising the execution of agreements and contracts and causing delays in the progress of processes. It was found that it is necessary investment in technical training, preventive actions and daily monitoring, targeting the correct fulfillment of the requirements for capturing public resources. It is essential to adopt the merit of legitimacy organizational as a mechanism to be able to retain, develop, attract and motivate city officials to work in Project Teams. The main contributions of this study are to provoke reflections on the dynamics of raising public resources for development projects and programs. Was identified a lack of trained technicians and municipal managers to present suitable projects, to identify problems in the implementation of agreements and correct irregularities pointed out in the Ancillary Service Information for Voluntary Transfers - Cauc. It was found that managerial failure causes impacts both in teams of job, as in the progress of the municipality. Keywords: work teams, fundraising, projects.

Controles sobre o Judiciário geram governança e eficiência? Estudo sobre o CNJ e a Justiça Estadual

O objetivo desta tese é investigar a atuação do órgão de controle judicial no Poder Judiciário, focando na dimensão “Desempenho Administrativo Judicial”. Esta tese visa complementar o modelo de Taylor (2008) adicionando o CNJ como um elemento da melhoria do desempenho dos tribunais, por meio da implantação de ferramentas gerenciais e ocasionando impactos políticos e institucionais. O estudo se apoia no contexto político e organizacional do Judiciário para apresentar um complemento ao entendimento vigente sobre os mecanismos de mensuração de desempenho. Os impactos do CNJ foram analisados a partir de sete aspectos do processo de Reforma do Judiciário: 1. Padronização das estruturas; 2. Sistemas de gerenciamento centralizados; 3. Padronização de procedimentos internos; 4. Centralização orçamentária; 5. Financiamento de unidades judiciais; 6. Procedimentos disciplinar contra irregularidades e más condutas de magistrados; 7. Critérios meritocráticos e promoção de magistrados. Os dados foram coletados por meio de entrevistas estruturadas com ex-conselheiros e conselheiros atuais do CNJ e considerou os dez anos de existência do CNJ (2004-2013), fornecendo uma perspectiva longitudinal. A análise temática ou categorial foi escolhida como a principal da técnica de análise de conteúdo. Os dados foram segmentados por questões, por categorias prévias e por categorias estabelecidas posteriormente. Foi evidenciado que o CNJ apresenta um efeito direto de atuação no “Desempenho Administrativo Judicial”: i) usando ferramentas de gestão que permitem os tribunais aprimorar a organização interna e elevar o nível de maturidade de governança; ii) moralizando e fiscalizando os Tribunais por meio de inspeções frequentes realizadas pela Corregedoria Nacional de Justiça que objetiva a resolução das irregularidades e o afastamento dos magistrados com más condutas no exercício do cargo. As evidências identificaram também impactos indiretos: i) o CNJ como um coordenador de ações do Judiciário, articulando melhor as relações com os representantes do Executivo e do Legislativo na obtenção de mais recursos orçamentários e financeiros para os tribunais; ii) o CNJ aumenta a autonomia do Judiciário reconhecendo os esforços de gestão dos tribunais e compartilhando as melhores práticas com os outros tribunais, com impactos na melhoria de infraestrutura e no desempenho. O aumento de controle promovido pelo CNJ reforçou a governança e a eficiência dos tribunais, mas com perca de autonomia num primeiro momento. Por outro lado, num segundo momento, possibilitou uma mudança de perfil nas indicações de seus conselheiros numa tentativa de enfraquecer o controle e aumentar autonomia dos tribunais.

Ferramentas de controle interno da controladoria geral da União: instrumentos de fiscalização da gestão, controle social e combate a corrupção

A administração pública exerce o seu poder de fiscalização por intermédio dos controles externo e interno, nos níveis federal, estadual e municipal, atuando como representante do papel no lugar do cidadão na gestão dos bens públicos. A correta utilização dos recursos públicos tem sido motivo de preocupação da administração pública, não só quanto à existência de corrupção de agentes públicos e políticos, mas também pela má gestão, pela falta de eficácia, eficiência, efetividade e economicidade quando da execução de recursos por meio das políticas públicas. O objetivo desta pesquisa foi analisar a questão da governança na administração pública, sua eficiência no sentido amplo, na vertente do controle interno e controle social como forma de combate à corrupção. Este estudo buscou analisar o controle social nas ações investigativas do governo federal brasileiro, realizadas pela Controladoria Geral da União (CGU), por intermédio das Demandas Externas que são instrumentos de controle interno desenvolvidos pela CGU, são ferramentas de auditoria utilizadas no controle que proporcionam a fiscalização imediata por representantes de entidades e cidadãos, gerando relatórios e pedidos de informações para que o gestor se manifeste sobre impropriedades e irregularidades na execução de políticas públicas. As demandas externas processadas pela Controladoria Geral da União e estão ligadas diretamente ao momento de fiscalização prévia e concomitante, também se relacionam com a questão do controle social enfatizando a participação popular, podendo ser iniciadas não somente a partir de denúncias formuladas pelos órgãos do poder público e imprensa, mas a partir do próprio cidadão que diretamente exerce seu poder de fiscalização, havendo o uso desse instrumento aumentado significativamente nos últimos anos, principalmente por meio da internet. A relevância do estudo é importante na verificação da inciativa dessas demandas, outrora sempre feita por parte de órgãos da estrutura burocrática do Estado, começa a fomentar o cidadão à participação, isso aumenta o controle social e o accountability vertical.

Fragilidades dos mecanismos de controle das organizações sociais de saúde no município do Rio de Janeiro

Nosso problema de pesquisa neste trabalho é a avaliação do funcionamento dos principais mecanismos de controle das organizações sociais de saúde, no caso específico do Município do Rio de Janeiro. As reiteradas denúncias de irregularidades e ilegalidades pelo Tribunal de Contas do Município do Rio de Janeiro e pelo Ministério Público do Estado do Rio de Janeiro levantaram dúvidas acerca da adequação dos processos de monitoramento, fiscalização e controle dessas entidades. Disto decorre nosso objetivo central de pesquisa, que é identificar as fragilidades do novo modelo de gestão por organizações sociais de saúde, no caso da cidade do Rio de Janeiro. Para isso, foram analisados: o arcabouço jurídico-normativo do modelo local, a partir de análise comparativa da legislação municipal que regulamenta seu funcionamento (Lei 5.026/09) e sua contraparte federal (Lei 9.637/98); indicadores de saúde que mensurassem o desempenho das OSS; todas as inspeções realizadas pelo TCM-RJ até o fim de 2015; e o conjunto de recomendações enviado pelo MP-ERJ para a Prefeitura após deflagração da Operação Ilha Fiscal, que acarretou a desqualificação da OS BIOTECH e a prisão de seus dirigentes, acusados de desviar mais de R$48 milhões em recursos públicos. Ao final, constatouse que as fragilidades da legislação municipal e dos decretos executivos que regulamentam a atuação das OSS no MRJ não permitem o exercício efetivo do comando da parceria, em afronta, portanto, ao dispositivo constitucional que determina que a atuação de entidades privadas no âmbito do SUS pode se dar apenas de modo complementar. Ademais, verificou-se total inadequação da estrutura de controle pela Prefeitura, cuja principal consequência foi tornar o modelo de reforma gerencialista em um modelo que incentiva o comportamento patrimonialista no âmbito da saúde pública, uma vez que o controle de meios é absolutamente negligenciado.

The impact of corruption on the performance of state-owned companies: case of Petrobras Brasil

As empresas estatais são freqüentemente consideradas como componentes cruciais da economia de um país. Eles são responsáveis pela criação de vários postos de trabalho e proveem serviços essenciais que exigem um grande investimento de capital. Porém, em países com instituições fracas, onde a responsabilidade dos políticos é limitada e a gestão dos recursos financeiros das empresas estatais sofre pouco controle, os funcionários são muitas vezes tentados pela corrupção. Enormes quantidades de fundos públicos são facilmente desviados, e dinheiro que deveria ter sido investido nas despesas de capital, no pagamento de dívida da empresa ou no aumento do retorno para os acionistas, é usado para aumentar a riqueza privada de indivíduos ou para financiar ilegalmente partidos políticos. O desempenho da empresa sofre com essas alienações visto que parte dos lucros da empresa não são reinvestidos na empresa e dado que incentivos dos gestores estão desalinhados com os interesses dos acionistas. Petrobras, a maior empresa da América Latina em termos de ativos e receitas anuais, sofreu em 2014 e 2015 um escândalo de corrupção imenso, cujo impacto económico foi considerável, levando ao enfraquecimento da confiança de muitos investidores no Brasil após o evento. O escândalo expôs um extenso esquema de corrupção através do qual os contratantes foram conspirando para aumentar os preços de contratos de construção, com a aprovação da administração da Petrobras que pediu em troca ganhos pessoais ou fundos para o Partido dos Trabalhadores (PT). A exposição do escândalo na imprensa brasileira teve um grande impacto sobre a credibilidade da Petrobras: as contas da empresa estavam escondendo imensas irregularidades dado que a empresa tinha pago demais para os contratos de construção que não foram precificados no valor do mercado. Ao longo deste estudo, usamos o exemplo da Petrobras para ilustrar como a corrupção dentro empresas estatais prejudica o desempenho da empresa e como ela afeta as várias partes interessadas da empresa.

Applying DEMO to model and automate a process in a workflow system: a case study in a city hall

Organizations are Complex systems. A conceptual model of the enterprise is needed that is: coherent the distinguished aspect models constitute a logical and truly integral comprehensive all relevant issues are covered consistent the aspect models are free from contradictions or irregularities concise no superfluous matters are contained in it essential it shows only the essence of the enterprise, i.e., the model abstracts from all realization and implementation issues. The world is in great need for transparency about the operation of all the systems we daily work with, ranging from the domestic appliances to the big societal institutions. In this context the field of enterprise ontology has emerged with the aim to create models that help to understand the essence of the construction and operation of complete systems; more specifically, of enterprises. Enterprise ontology arises in the way to look through the distracting and confusing appearance of an enterprise right into its deep kernel. This, from the perspective of the system designer gives him the tools needed to design a successful system in a way that’s reflects the desires and needs of the workers of the enterprise. This project’s context is the use of DEMO (Design and Engineering Methodology for Organizations) for (re)designing or (re)engineering of an enterprise, namely a process of the construction department of a city hall, the lack of a well-founded theory about the construction and operation of this processes that was the motivation behind this work. The purpose of studying applying the DEMO theory and method was to optimize the process, automating it as much as possible, while reducing paper and time spent between tasks and provide a better service to the citizens.

Desenvolvimento de um sistema de planejamento, gestão de serviços e controle de custos em obras de construção civil

The increasing competitiveness of the construction industry, set in an economic environment in which the offer is now greater than the demand , causes the prices of many products and services, are strongly influenced by the processes of production and the final consumer. Thus, to become more competitive in the market and construction companies are seeking new alternatives to reduce and control costs, production processes and tools that allow for close monitoring of the construction schedule, with the consequent compliance deadline with the client. Based on this scenario, the creation of control tools, service management and planning work emerges as an investment opportunity and an area that can promote great benefits to construction companies. The goal of this work is to present a system of planning, service management and costs control that through worksheets provide information relating to the production phase of the work, allowing the visualization of possible irregularities in the planning and cost of the enterprise, enabling the company to take steps to achieve the goals of the enterprise in question, and correct them when necessary. The developed system has been used in a piece of real estate in Rio Grande do Norte, and the results showed that its use together allowed the construction company to accompany their results and take corrective and preventive actions during the production process, efficiently and effective

Estudo das propriedades termofísicas com variação da expansibilidade de compósito desenvolvido com matriz PUR-NOP e carga funcional de argilomineral

In this study were conducted experimental procedures for determination of variation of the expandability of rigid polyurethane foam (PUR) from a natural oil polyol (NOP), specifically the Castor oil plant, Ricinus communis, pure and additions of the vermiculite in phase dispersed in different percentage within a range from 0% to 20%, mass replacement. From the information acquired, were defined the parameters for production of bodies of test, plates obtained through controlled expansion, with the final volume fixed. Initially, the plates were subjected to thermal performance tests and evaluated the temperature profiles, to later be extracted samples duly prepared in accordance with the conditions required for each test. Was proceeded then the measurement of the coefficient of thermal conductivity, volumetric capacity heat and thermal diffusivity. The findings values were compared with the results obtained in the tests of thermal performance, contributing to validation of the same. Ultimately, it was investigated the influence that changes in physical-chemical structure of the material had exerted on the variation of thermophysical quantities through gas pycnometry, scanning electron microscopy (SEM) combined with energy dispersive X-ray fluorescence spectroscopy (EDXRF), infrared spectroscopy using Fourier transform (FTIR), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Based on the results obtained was possible to demonstrate that all load percentage analyzed promoted an increase in the potential expansion (PE) of the resin. In production of the plates, the composites with density near at the free expansion presented high contraction during the cure, being the of higher density adopted as definitive standard. In the thermal performance tests, the heating and cooling curves of the different composites had presented symmetry and values very close for lines of the temperature. The results obtained for the thermophysical properties of composites, showed little difference in respect of pure foam. The percentage of open pores and irregularities in the morphology of the composites were proportionate to the increment of vermiculite. In the interaction between the matrix and dispersed phase, there were no chemical transformations in the region of interface and new compounds were not generated. The composites of PUR-NOP and vermiculite presented thermal insulating properties near the foam pure and percentage significantly less plastic in its composition, to the formulation with 10% of load

Simulação do sistema de esgotamento sanitário de Ponta Negra- Natal: mitigação dos riscos ambientais e estratégia de manutenção preditiva

The simulation of SES-Natal Ponta Negra: mitigation of environmental risks and predictive maintenance strategy was developed in the context of several operational irregularities in the pumping stations and sewage systems in the system Ponta Negra. Thus, the environmental risks and complaints against the company due to overflows of sewage into the public thoroughfare became common. This neighborhood has shown in recent years an increase of resident higher than the initial expectation of growth. In this sense presumed the large population growth and generation of sewers higher than expected, associated to the use of corrective maintenance and misuse of the system may be the main causes of operational failures occurring in the SES. This study aimed at analyzing the hydraulic behavior of SES Ponta Negrathrough numerical simulation of its operation associated to future scenarios of occupation. The SES Ponta Negra has a long lengthof collection networks and 6 pumping stations interconnected, being EE 1, 2, 4 coastal way, and beach Shopping interconnected EE3 to receives all sewers pumped from the rest pumping station and pumped to the sewage treatment station of neighborhood which consists of a facultative pond followed by three maturation ponds with disposal of treated effluent into infiltration ditches. Oncethey are connected with each other, the study was conducted considering the days and times of higher inflow for all lifts. Furthermore, with the aim of measuring the gatherer network failures were conducted data survey of on the networks. Thephysical and operational survey data was conducted between January/2011 and janeiro/2012. The simulation of the SES was developed with the aim ofdemonstrating its functioning, eithercurrently and in the coming years, based in population estimates and sewage flow. The collected data represents the current framework of the pumping stations of the SES Ponta Negra and served as input to the model developed in MS Excel ® spreadsheet which allowed simulating the behavior of SES in future scenarios. The results of this study show thatBeach Shopping Pumping Station is actually undersized and presents serious functioning problemsthatmay compromise the environmental quality of surrounding area. The other pumping stations of the system will reach itsmaximum capacity between 2013 and 2015, although the EE1 and EE3 demonstrateoperation capacity, even precariously, until 2017. Moreover, it was observed that the misuse of the network system, due to the input of both garbage and stormwater, are major factors of failures that occur in the SES. Finally, it was found that the corrective maintenance appliance, rather than predictive,has proven to beinefficient because of the serious failuresin the system, causing damage to the environment and health risks to users

Intercomparison of integrated water vapor estimates from multisensors in the amazonian region

Water vapor is an atmospheric component of major interest in atmospheric science because it affects the energy budget and plays a key role in several atmospheric processes. The Amazonian region is one of the most humid on the planet, and land use change is able to affect the hydrologic cycle in several areas and consequently to generate severe modifications in the global climate. Within this context, accessing the error associated with atmospheric humidity measurement and the validation of the integrated water vapor (IWV) quantification from different techniques is very important in this region. Using data collected during the Radiation, Cloud, and Climate Interactions in Amazonia during the Dry-to-Wet Transition Season (RACCI/DRY-TO-WET), an experiment carried out in southwestern Amazonia in 2002, this paper presents quality analysis of IWV measurements from RS80 radiosondes, a suite of GPS receivers, an Aerosol Robotic Network (AERONET) solar radiometer, and humidity sounding from the Humidity Sounder for Brazil (HSB) aboard the Aqua satellite. When compared to RS80 IWV values, the root-mean-square (RMS) from the AERONET and GPS results are of the order of 2.7 and 3.8 kg m(-2), respectively. The difference generated between IWV from the GPS receiver and RS80 during the daytime was larger than that of the nighttime period because of the combination of the influence of high ionospheric activity during the RACCI experiment and a daytime drier bias from the RS80.
