This research work is focused to show the changes in educational administration from the agreements between the Mossoró / RN and the Ayrton Senna Institute IAS, for education provision. Nowadays, the partnership policy is a constitutive element of the reform of the Brazilian State, which dropped its action on social policies and to strengthen its regulatory role, encouraging private participation in planning, preparation and implementation of public policies, new printing setting the political-social. In this context, the 10 Note Management Programme, developed by the IAS, is part of the neoliberal logic of modernization of public school systems, focusing on results and developing strategies for control and regulation of schools work and its efficiency, effectiveness and greater productivity. The 10 Note focuses on two dimensions: the management of learning and teaching in networking, in a managerial perspective to overcome the culture of failure (expressed as age-grade, dropout and repetition rates in) and implantation of culture of success (as measured in the improvement of the indices). To understanding the process, we have delimited as the object of study, the process of implementing them mentioned program in the city, which its objective is to analyze implications for the school community from the perspective of democratic management, adopting the dimensions of autonomy and participation in institutional processes as a criterion of analysis. From a methodological point of view, the survey was conducted from a literature review and documentary about educational policy developed in the country since the 1990´s, seeking to understand, in a dialectical perspective, the political dimensions of teaching, training and performance of the subjects involved in the school work. Besides the empirical observation, it was also used semi-structured interviews with a methodological tool for gathering information and opinions about the partnership and the implementation of the 10 Note Management Program in the county. The interviewee participants were ex-former education managers, coordinators, school managers, secretaries and teachers. Regarding the dimensions inside the analysis (autonomy and participation), the research led to the conclusion: that GEED, under the guidance of IAS promoted regulation of school autonomy, set up the selection process for exercising the office of school administration and system awards to schools, pupils and teachers, subject to results, there is mismatch between the managerial logic and the democratic management principles, that the ideological discourse of modernization of municipal management coexists with traditional practices, centralizing patronage, which ignores the democratic participation in the school decisions processes, the goals of the partnership were partially achieved, since that the city has improved over the approval and dropouts, although the approval of the Education Municipal Plan of the rules institutional (administrative, financial and educational) and the creation of the Councils observed that the school community participation is still limited, not being characterized as a coordinated intervention, capable of promoting the transformation and improvement its quality in the county. In the same way, the orientation of networking is a limit to the autonomy of schools, given the external definition of goals and strategies to be adopted, along with pressure exerted through the accountability of each school community for their achievements

Abstract. Background: The use of potentially inappropriate medications (PIM) among the elderly is a serious public health problem because it is intrinsically linked to increased morbidity and mortality, causing high costs to public health systems. This study's objective was to verify the prevalence of and the factors associated with the use of PIMs by elderly Brazilians in institutional settings. Methods. We performed a transversal study, by consulting the case files of elderly people living in Long Term Care for the Elderly (LTC) in towns in the State of São Paulo, Brazil, as well as structured interviews with the nurses responsible for them.We identified PIMs using the list of recently updated Beers criteria developed by a group of specialists from the American Geriatrics Society (AGS), who reviewed the criteria based on studies with high scientific evidence levels. We defined the factors studied to evaluate the association with PIM use prior to the statistical analyses, which were the chi-square test and multiple logistic regression. Results: Among the elderly who used drugs daily, 82.6% were taking at least one PIM, with antipsychotics (26.5%) and analgesics (15.1%) being the most commonly used. Out of all the medications used, 32.4% were PIMs, with 29.7% of these being PIMs that the elderly should avoid independent of their condition, 1.1% being inappropriate medication for older adults with certain illnesses or syndromes, and 1.6% being medications that older adults should use with caution. In the multivariate analysis, the factors associated with PIM use were: polypharmacy (p = 0.0187), cerebrovascular disease (p = 0.0036), psychiatric disorders (p < 0.0001) and dependency (p = 0.0404). Conclusions: The results of this study showed a high prevalence of PIM use in institutionalized elderly Brazilian patients. and the associated factors were polypharmacy, psychiatric disorders, cerebrovascular diseases and dependency. © 2013 Lima et al.; licensee BioMed Central Ltd.

Este estudo tem como tema a violência doméstica contra professoras e toma como objeto os registros sobre esse fato presentes em Inquéritos Policiais da Delegacia de Atendimento à Mulher de Santarém-PA. A questão central da pesquisa consiste em problematizar: quais articulações entre a condição de violentada e o status profissional de professora são apresentadas no processo de denúncia, via inquérito policial, por professoras em situação de violência doméstica no município de Santarém? A partir dessa indagação central o objetivo geral da pesquisa volta-se para analisar as articulações entre a condição de violentada e o status profissional de professora presentes nos inquéritos policiais, articulado com a investigação das confluências entre as discussões sobre as relações de gênero, a violência doméstica e os direitos humanos das mulheres e a compreensão das formas de atravessamento entre os marcadores sociais das professoras em situação de violência doméstica. O tratamento metodológico foi pautado em um estudo qualitativo que se vale da pesquisa documental, por meio da análise de conteúdo dos Inquéritos Policiais da DEAM de Santarém, documentos estes que registram não só a ocorrência da violência como também o contexto em que ocorreram os atravessamentos dos diferentes marcadores sociais assumidos pelos sujeitos, autores das agressões e agredidas e suas intersecções. O marco teórico da pesquisa está pautado na perspectiva relacional que busca compreender a violência contra as mulheres resultantes das redes de relações de poder entre homens e mulheres e entre estes e os marcadores sociais que assumem. As análises conclusivas evidenciam que as tramas da violência doméstica contra as mulheres são complexas e marcadas por questões, tais como: a persistência na submissão à violência doméstica das docentes embora independam economicamente do agressor; a diferença geracional entre as docentes e os autores das agressões é marcada por homens mais jovens versus mulheres maduras, em processo de envelhecimento; o baixo nível de escolaridade dos agressores e o baixo prestígio da ocupação que desenvolvem em relação ao nível de escolaridade e posição social da profissão das docentes agredidas que possuem profissão definida, de natureza intelectual e reconhecida socialmente; as denúncias contra os autores das agressões só ocorreram após os motivos extremos de ameaças de morte e exposição pública da violência em uma profissão de natureza pública, a de professora; que o registro da ocorrência concretiza a alternância de poder nas relações de gênero e da própria violência doméstica, visto que na dinâmica da circulação de poder com os autores das agressões, as professoras agredidas reconheceram-se também como detentoras de poder, avançando da condição de vítimas para a de protagonistas; que na situação de violentadas, as professoras, foram capazes de perceber fios invisíveis naturalizados na teia da violência doméstica, partindo para o enfrentamento público, a denúncia.

In recent years, public schools have experienced the deployment of external evaluation that, legally, should promote the development and deployment aimed at enhancing the educational process of teaching offered at the country's public policy systems. However, such a situation occurred in a broader regulations of teaching and managerial measures and performative nature context generated implications in everyday school life, notably due to the pressure exerted on schools before the publicity of accountability for results and performance indicators changing, in many cases, the purpose of teaching work. In this context we understand that it is very important to discuss the history and characterization of implanted a city in São Paulo state systems, and vision teachers about them, and the consequences that assessments have caused in practice in the classroom. So be performed an empirical research of qualitative nature in four elementary schools-cycle Teaching I and II, with the aim of analyzing the perception of teachers about external reviews of a municipal school. As an instrument for data collection dense interview with teachers that will be used will be audio-recorded and then transcribed and analyzed with the support of the theoretical frameworks adopted

Decomposition based approaches are recalled from primal and dual point of view. The possibility of building partially disaggregated reduced master problems is investigated. This extends the idea of aggregated-versus-disaggregated formulation to a gradual choice of alternative level of aggregation. Partial aggregation is applied to the linear multicommodity minimum cost flow problem. The possibility of having only partially aggregated bundles opens a wide range of alternatives with different trade-offs between the number of iterations and the required computation for solving it. This trade-off is explored for several sets of instances and the results are compared with the ones obtained by directly solving the natural node-arc formulation. An iterative solution process to the route assignment problem is proposed, based on the well-known Frank Wolfe algorithm. In order to provide a first feasible solution to the Frank Wolfe algorithm, a linear multicommodity min-cost flow problem is solved to optimality by using the decomposition techniques mentioned above. Solutions of this problem are useful for network orientation and design, especially in relation with public transportation systems as the Personal Rapid Transit. A single-commodity robust network design problem is addressed. In this, an undirected graph with edge costs is given together with a discrete set of balance matrices, representing different supply/demand scenarios. The goal is to determine the minimum cost installation of capacities on the edges such that the flow exchange is feasible for every scenario. A set of new instances that are computationally hard for the natural flow formulation are solved by means of a new heuristic algorithm. Finally, an efficient decomposition-based heuristic approach for a large scale stochastic unit commitment problem is presented. The addressed real-world stochastic problem employs at its core a deterministic unit commitment planning model developed by the California Independent System Operator (ISO).

Opportunistic diseases caused by Human Immunodeficiency Virus (HIV) and Hepatitis B Virus (HBV) is an omnipresent global challenge. In order to manage these epidemics, we need to have low cost and easily deployable platforms at the point-of-care in high congestions regions like airports and public transit systems. In this dissertation we present our findings in using Localized Surface Plasmon Resonance (LSPR)-based detection of pathogens and other clinically relevant applications using microfluidic platforms at the point-of-care setting in resource constrained environment. The work presented here adopts the novel technique of LSPR to multiplex a lab-on-a-chip device capable of quantitatively detecting various types of intact viruses and its various subtypes, based on the principle of a change in wavelength occurring when metal nano-particle surface is modified with a specific surface chemistry allowing the binding of a desired pathogen to a specific antibody. We demonstrate the ability to detect and quantify subtype A, B, C, D, E, G and panel HIV with a specificity of down to 100 copies/mL using both whole blood sample and HIV-patient blood sample discarded from clinics. These results were compared against the gold standard Reverse Transcriptase Polymerase Chain Reaction (RT-qPCR). This microfluidic device has a total evaluation time for the assays of about 70 minutes, where 60 minutes is needed for the capture and 10 minutes for data acquisition and processing. This LOC platform eliminates the need for any sample preparation before processing. This platform is highly multiplexable as the same surface chemistry can be adapted to capture and detect several other pathogens like dengue virus, E. coli, M. Tuberculosis, etc.

OBJECTIVES Respondent-driven sampling (RDS) is a new data collection methodology used to estimate characteristics of hard-to-reach groups, such as the HIV prevalence in drug users. Many national public health systems and international organizations rely on RDS data. However, RDS reporting quality and available reporting guidelines are inadequate. We carried out a systematic review of RDS studies and present Strengthening the Reporting of Observational Studies in Epidemiology for RDS Studies (STROBE-RDS), a checklist of essential items to present in RDS publications, justified by an explanation and elaboration document. STUDY DESIGN AND SETTING We searched the MEDLINE (1970-2013), EMBASE (1974-2013), and Global Health (1910-2013) databases to assess the number and geographical distribution of published RDS studies. STROBE-RDS was developed based on STROBE guidelines, following Guidance for Developers of Health Research Reporting Guidelines. RESULTS RDS has been used in over 460 studies from 69 countries, including the USA (151 studies), China (70), and India (32). STROBE-RDS includes modifications to 12 of the 22 items on the STROBE checklist. The two key areas that required modification concerned the selection of participants and statistical analysis of the sample. CONCLUSION STROBE-RDS seeks to enhance the transparency and utility of research using RDS. If widely adopted, STROBE-RDS should improve global infectious diseases public health decision making.

The Education for All Handicapped Children Act of 1975, P.L. 94-142, created a new challenge for the nation's public school systems. During 1982-1983, a national study, called the "Collaborative Study of Children with Special Needs", was conducted in 5 metropolitan school districts to evaluate the effectiveness of education and health care services of children in kindergarten to 6th grade being provided under P.L. 94-142 programs. This dissertation (the Substudy) was undertaken to augment the findings of the Collaborative Study. The purpose of this study was to develop a database to provide descriptive information on the demographic, service and health characteristics of a small group of 3 and 4 year old handicapped children served by the Houston Independent School District (HISD) during 1982-1983.^ The study involved a stratified sample of 105 three and four year old children divided into 3 groups according to type of handicapping condition.^ The results of the study gave a clearer picture of the demographic characteristics of these Pre-K children. Specifically, sex ratio was approximately one, lower than the national norm. Family and socioeconomic characteristics were assessed.^ The study used an independence/dependence index composed of 11 items on the parent questionnaire to assess the level of functional independence of each child. An association was found between index scores and parent-reported effects of the child on family activity. Parents who said that their child's condition had affected the family's job situation, housing accomodations, vacation plans, marriage, choice of friends and social activities were also more likely to report less independence in the child. In addition, many of the Substudy children had extensive care-taking needs reflected in specific components of the index such as dressing, feeding, toileting or moving about the house.^ In general the results of the Pre-K Substudy indicate that at the early childhood level, the HISD special education program is functioning well in most areas and that parents are very satisfied with the program.

Tiled projector displays are a common choice for training simulators, where a high resolution output image is required. They are cheap for the resolution that they can reach and can be configured in many different ways. Nevertheless, such kinds of displays require geometric and color correction so that the composite image looks seamless. Display correction is an even bigger challenge when the projected images include dark scenes combined with brighter scenes. This is usually a problem for railway simulators when the train is positioned inside a tunnel and the black offset effect becomes noticeable. In this paper, a method for fast photometric and geometric correction of tiled display systems where dark and bright scenes are combined is presented. The image correction is carried out in two steps. First, geometric alignment and overlapping areas attenuation for brighter scenes is applied. Second, in the event of being inside a tunnel, the brightness of the scene is increased in certain areas using light sources in order to create the impression of darkness but minimizing the effect of the black offset

Los sistemas de proyección multi-proyector han adquirido gran popularidad en los últimos años para su uso en un amplio rango de aplicaciones como sistemas de realidad virtual, simuladores y visualización de datos. Esto es debido a que normalmente estas aplicaciones necesitan representar sus datos a muy alta resolución y a lo largo de una gran superficie. Este tipo de sistemas de proyección son baratos en comparación con las resoluciones que pueden conseguir, se pueden configurar para proyectar sobre prácticamente cualquier tipo de superficie, sea cual sea su forma, y son fácilmente escalables. Sin embargo, para hacer que este tipo de sistemas generen una imagen sin discontinuidades geométricas o colorimétricas requieren de un ajuste preciso. En la presente tesis se analizan en detalle todos los problemas a los que hay que enfrentarse a la hora de diseñar y calibrar un sistema de proyección de este tipo y se propone una metodología con una serie de optimizaciones para hacer el ajuste de estos sistemas más sencillo y rápido. Los resultados de esta metodología se muestran aplicados a la salida gráfica de un simulador de entrenamiento. Multi-projector display systems have gained high popularity over the past years for its use in a wide range of applications such as virtual reality systems, simulators or data visualization where a high resolution image over a large projection surface is required. Such systems are cheap for the resolutions they can provide, can be configured to project images on almost any kind of screen shapes and are easily scalable, but in order to provide a seamless image with no photometric discontinuities they require a precise geometric and colour correction. In this thesis, we analyze all the problems that have to be faced in order to design and calibrate a multi-projector display. We propose a calibration methodology with some optimizations that make the adjustment of this kind of displays easier and faster. The results of the implementation of this methodology on a training simulator are presented and discussed

The paper describes some relevant results of an on-going research aiming to elaborate a methodology to help the mobility management in natural parks, compatible with their protection missions: it has been developed a procedure to reproduce the mobility-environment relationships in various operational conditions. The final purpose is the identification of: a) the effects of various choices in transport planning, both at long term and strategic level; b) the most effective policies of mobility management. The work is articulated in the following steps: 1) definition of protected area on the basis of ecological and socio-economic criteria and legislative constraints; 2) analysis of mobility needs in the protected areas; 3) reconstruction of the state of the art of mobility management in natural parks at European level; 4) analysis of used traffic flows measurement methods; 5) analysis of environmental impacts due to transport systems modelling (air pollution and noise only); 6) identification of mitigation measures to be potentially applied. The whole methodology has been tested and validated on Italian case studies: i) the concerned area has been zoned according to the land-use peculiarities; ii) the local situations of transport infrastructure (roads and parking), services (public transport systems) and rules (traffic regulations) have been mapped with references to physical and functional attributes; iii) the mobility, both systematic and touristic, has been represented in an origin-destination matrix. By means of an assignment model the flows have been distributed and the corresponding average speeds to quantify gaseous and noise emissions was calculated, the criticalities in the reference scenario have been highlighted, as well as some alternative scenarios, including both operational and infrastructural measures have been identified. The comparison between projects and reference scenario allowed the quantification of effects (variation of emissions) for each scenario and a selection of the most effective management actions to be taken.

The final purpose is the identification of: a) the effects of various choices in transport planning, both at long term and strategic level; b) the most effective policies of mobility management. The preliminary work was articulated in the following steps: 1) definition of protected area on the basis of ecological and socio-economic criteria and legislative constraints; 2) analysis of mobility needs in the protected areas; 3) reconstruction of the state of the art of mobility management in natural parks at European level; 4) analysis of used traffic flows measurement methods; 5) analysis of environmental impacts due to transport systems modelling (limited to air pollution and noise); 6) identification of mitigation measures to the potentially applied. The whole methodology has been firstly tested on the case study of the National Park of ?Gran Sasso and Monti della Laga? and further validated on the National Park of ?Gargano?, both located Italy: i) the concerned area has been zoned according to the land-use peculiarities; ii) the local situations of transport infrastructure (roads and parking), services (public transport systems) and rules (traffic regulations) have been mapped with references to physical and functional attributes; iii) the mobility, both systematic and touristic, has been synthetically represented in an origin-destination matrix. By means of an assignment model it has been determined the distribution of flows and the corresponding average speeds to quantify gaseous and noise emissions. On this basis the environmental criticalities in the reference scenario have been highlighted, as well as some alternative scenarios including both operational and infrastructural measures have been identified. The comparison between the projects and the reference scenario allowed the quantification of the effects (variation of emissions) for each scenario and a selection of the most effective management actions to be taken.
