Uso das estatísticas criminais e planejamento das atividades policiais: um estudo sobre a percepção dos profissionais de segurança pública do estado do Rio de Janeiro

O presente estudo teve como objetivo analisar o uso das estatísticas criminais no planejamento das atividades policiais no estado do Rio de Janeiro, identificando as possibilidades e as dificuldades para este uso segundo as percepções dos profissionais de segurança pública envolvidos neste processo. Partiu-se da hipótese que embora já haja um movimento para utilização das estatísticas criminais no estado do Rio de Janeiro, na prática a sua utilização nos moldes das abordagens contemporâneas de políticas de segurança pública é prejudicada por resistências culturais dos atores envolvidos e por problemas de natureza estrutural, como insuficiência de recursos materiais e humanos. Tal tese foi defendida tendo por base a triangulação do referencial teórico adotado e das pesquisas documental e de campo desenvolvidas. A pesquisa de campo foi realizada por meio de entrevistas em profundidade com policiais civis, policiais militares, analistas e gestores públicos envolvidos com o uso deste instrumento de análise. Os resultados da investigação permitiram concluir que no estado do Rio de Janeiro já ocorre de fato o uso dos dados estatísticos criminais, marcado principalmente pela implementação do Sistema de Metas para os Indicadores Estratégicos de Criminalidade do Estado. Não obstante, evidenciou que na prática o uso das estatísticas encontra barreiras não só de natureza técnica, como de natureza subjetiva, pois lida com interesses de múltiplos atores envolvidos. Deste modo, tendo com pano de fundo o modelo de processo decisório de Kingdon, chegou-se ao pressuposto de que este tema precisa ser inserido na agenda decisória governamental, com propostas de políticas públicas que garantam as condições concretas (materiais e de recursos humanos) para o uso das estatísticas criminais e ações que visem minimizar as resistências encontradas na prática, com medidas que estimulem a integração entre os diferentes atores inseridos neste processo.

10 anos de MINUSTAH: uma avaliação de suas consequências políticas para o Brasil

A literatura Operações de Paz é farta de exemplos de análise de desempenho de uma operação. Essas análises observam o cumprimento do mandato, ou os efeitos no Estado hospedeiro. Mas poucos estudos, tratam das consequências dessa participação para os Estados que enviam tropas. Tentando ajudar a preencher essa lacuna, esta dissertação pretende entender se a participação e o protagonismo brasileiro na Missão das Nações Unidas para a Estabilização do Haiti - MINUSTAH ajudaram o Brasil a alcançar seus objetivos. Utilizando uma abordagem mista, foram analisados dados de contribuição de tropas, orçamentos, documentos oficiais e, por fim, foram realizadas 08 entrevistas com militares e especialistas civis. Com base no modelo de objetivos estatais aplicado, se estudou se a presença no Haiti permitiu ao Brasil sinalizar seus objetivos para a comunidade internacional, reformar suas instituições, as militares entre elas, e se havia necessidades orçamentárias para contribuir para a missão. As evidências analisadas levam a crer que o saldo da missão é misto. Embora alguns aspectos demonstrem definitivas melhorias, outros são irrelevantes ou sofrem com a manutenção da cultura militar antiquada.

Um estudo sobre a preparação metalográfica da liga de aluminio AA7075-T6

The increasing technological innovation and demand for materials with better properties boosts research into new materials and new alloys. To do so, aluminum alloys are being developed, among them the AA7075-T6, having many applications in aerospace and military industries, machinery and equipment, molds for plastic injection and structures. To study and understand the properties, characteristics and especially the microstructure of the material, the metallographic preparation is essential. This paper presents new methodologies to achieve the metallography of samples of scrap alloy AA7075-T6, with emphasis on methods of polishing. For the five samples, the best results were those with specific grinding, the samples only going down on the sander. For polishing, the most effective method so far has been using the polishing cloth 16.3, of ATM enterprise, solution of diamond 3 μm, solution of diamond 1 μm, and colloidal solution of OP-S. For the etching, the reactive agent used was phosphoric acid (H3PO4) 85% P.A., as 90% in the proportion of distilled water to 10% acid. The best results were obtained in the attacks of 300 and 240 seconds, revealing the grain boundaries in most areas. Methodologies need more studies and more tests, but the results have proved to be satisfactory

Sistemi riconfigurabili a basso consumo per applicazioni di monitoraggio distribuito

The term Ambient Intelligence (AmI) refers to a vision on the future of the information society where smart, electronic environment are sensitive and responsive to the presence of people and their activities (Context awareness). In an ambient intelligence world, devices work in concert to support people in carrying out their everyday life activities, tasks and rituals in an easy, natural way using information and intelligence that is hidden in the network connecting these devices. This promotes the creation of pervasive environments improving the quality of life of the occupants and enhancing the human experience. AmI stems from the convergence of three key technologies: ubiquitous computing, ubiquitous communication and natural interfaces. Ambient intelligent systems are heterogeneous and require an excellent cooperation between several hardware/software technologies and disciplines, including signal processing, networking and protocols, embedded systems, information management, and distributed algorithms. Since a large amount of fixed and mobile sensors embedded is deployed into the environment, the Wireless Sensor Networks is one of the most relevant enabling technologies for AmI. WSN are complex systems made up of a number of sensor nodes which can be deployed in a target area to sense physical phenomena and communicate with other nodes and base stations. These simple devices typically embed a low power computational unit (microcontrollers, FPGAs etc.), a wireless communication unit, one or more sensors and a some form of energy supply (either batteries or energy scavenger modules). WNS promises of revolutionizing the interactions between the real physical worlds and human beings. Low-cost, low-computational power, low energy consumption and small size are characteristics that must be taken into consideration when designing and dealing with WSNs. To fully exploit the potential of distributed sensing approaches, a set of challengesmust be addressed. Sensor nodes are inherently resource-constrained systems with very low power consumption and small size requirements which enables than to reduce the interference on the physical phenomena sensed and to allow easy and low-cost deployment. They have limited processing speed,storage capacity and communication bandwidth that must be efficiently used to increase the degree of local ”understanding” of the observed phenomena. A particular case of sensor nodes are video sensors. This topic holds strong interest for a wide range of contexts such as military, security, robotics and most recently consumer applications. Vision sensors are extremely effective for medium to long-range sensing because vision provides rich information to human operators. However, image sensors generate a huge amount of data, whichmust be heavily processed before it is transmitted due to the scarce bandwidth capability of radio interfaces. In particular, in video-surveillance, it has been shown that source-side compression is mandatory due to limited bandwidth and delay constraints. Moreover, there is an ample opportunity for performing higher-level processing functions, such as object recognition that has the potential to drastically reduce the required bandwidth (e.g. by transmitting compressed images only when something ‘interesting‘ is detected). The energy cost of image processing must however be carefully minimized. Imaging could play and plays an important role in sensing devices for ambient intelligence. Computer vision can for instance be used for recognising persons and objects and recognising behaviour such as illness and rioting. Having a wireless camera as a camera mote opens the way for distributed scene analysis. More eyes see more than one and a camera system that can observe a scene from multiple directions would be able to overcome occlusion problems and could describe objects in their true 3D appearance. In real-time, these approaches are a recently opened field of research. In this thesis we pay attention to the realities of hardware/software technologies and the design needed to realize systems for distributed monitoring, attempting to propose solutions on open issues and filling the gap between AmI scenarios and hardware reality. The physical implementation of an individual wireless node is constrained by three important metrics which are outlined below. Despite that the design of the sensor network and its sensor nodes is strictly application dependent, a number of constraints should almost always be considered. Among them: • Small form factor to reduce nodes intrusiveness. • Low power consumption to reduce battery size and to extend nodes lifetime. • Low cost for a widespread diffusion. These limitations typically result in the adoption of low power, low cost devices such as low powermicrocontrollers with few kilobytes of RAMand tenth of kilobytes of program memory with whomonly simple data processing algorithms can be implemented. However the overall computational power of the WNS can be very large since the network presents a high degree of parallelism that can be exploited through the adoption of ad-hoc techniques. Furthermore through the fusion of information from the dense mesh of sensors even complex phenomena can be monitored. In this dissertation we present our results in building several AmI applications suitable for a WSN implementation. The work can be divided into two main areas:Low Power Video Sensor Node and Video Processing Alghoritm and Multimodal Surveillance . Low Power Video Sensor Nodes and Video Processing Alghoritms In comparison to scalar sensors, such as temperature, pressure, humidity, velocity, and acceleration sensors, vision sensors generate much higher bandwidth data due to the two-dimensional nature of their pixel array. We have tackled all the constraints listed above and have proposed solutions to overcome the current WSNlimits for Video sensor node. We have designed and developed wireless video sensor nodes focusing on the small size and the flexibility of reuse in different applications. The video nodes target a different design point: the portability (on-board power supply, wireless communication), a scanty power budget (500mW),while still providing a prominent level of intelligence, namely sophisticated classification algorithmand high level of reconfigurability. We developed two different video sensor node: The device architecture of the first one is based on a low-cost low-power FPGA+microcontroller system-on-chip. The second one is based on ARM9 processor. Both systems designed within the above mentioned power envelope could operate in a continuous fashion with Li-Polymer battery pack and solar panel. Novel low power low cost video sensor nodes which, in contrast to sensors that just watch the world, are capable of comprehending the perceived information in order to interpret it locally, are presented. Featuring such intelligence, these nodes would be able to cope with such tasks as recognition of unattended bags in airports, persons carrying potentially dangerous objects, etc.,which normally require a human operator. Vision algorithms for object detection, acquisition like human detection with Support Vector Machine (SVM) classification and abandoned/removed object detection are implemented, described and illustrated on real world data. Multimodal surveillance: In several setup the use of wired video cameras may not be possible. For this reason building an energy efficient wireless vision network for monitoring and surveillance is one of the major efforts in the sensor network community. Energy efficiency for wireless smart camera networks is one of the major efforts in distributed monitoring and surveillance community. For this reason, building an energy efficient wireless vision network for monitoring and surveillance is one of the major efforts in the sensor network community. The Pyroelectric Infra-Red (PIR) sensors have been used to extend the lifetime of a solar-powered video sensor node by providing an energy level dependent trigger to the video camera and the wireless module. Such approach has shown to be able to extend node lifetime and possibly result in continuous operation of the node.Being low-cost, passive (thus low-power) and presenting a limited form factor, PIR sensors are well suited for WSN applications. Moreover techniques to have aggressive power management policies are essential for achieving long-termoperating on standalone distributed cameras needed to improve the power consumption. We have used an adaptive controller like Model Predictive Control (MPC) to help the system to improve the performances outperforming naive power management policies.

Tra pacifismo e ambientalismo: il Nuclear Freeze Movement e la risposta dell'amministrazione Reagan

Negli anni Ottanta si assiste tanto nel vecchio quanto nel nuovo continente alla rinascita del movimento antinucleare. Mentre in Europa l’origine di questa ondata di proteste antinucleari è collegata alla “doppia decisione” NATO del 1979, negli Stati Uniti la genesi si colloca nel contesto dalla mobilitazione dei gruppi ambientalisti in seguito all’incidente alla centrale nucleare di Three Mile Island. Dopo l’elezione di Ronald Reagan, alle proteste contro le applicazioni pacifiche dell’atomo si affiancarono quelle contro la politica nucleare del Paese. La retorica di Reagan, il massiccio piano di riarmo, unitamente al rinnovato deteriorarsi delle relazioni tra USA e URSS contribuirono a diffondere nell’opinione pubblica la sensazione che l’amministrazione Reagan, almeno da un punto di vista teorico, non avesse escluso dalle sue opzioni il ricorso alle armi nucleari nel caso di un confronto con l’URSS. I timori legati a questa percezione produssero una nuova ondata di proteste che assunsero dimensioni di massa grazie alla mobilitazione provocata dalla Nuclear Weapons Freeze Campaign (NWFC). Il target della NWFC era l’ampio programma di riarmo nucleare sostenuto da Reagan, che secondo gli attivisti nucleari, in un quadro di crescenti tensioni internazionali, avrebbe fatto aumentare le possibilità di uno scontro atomico. Per evitare lo scenario dell’olocausto nucleare, la NWFC proponeva «un congelamento bilaterale e verificabile del collaudo, dell’installazione e della produzione di armi nucleari». L’idea del nuclear freeze, che era concepito come un passo per fermare la spirale del riarmo e tentare successivamente di negoziare riduzioni negli arsenali delle due superpotenze, riscosse un tale consenso nell’opinione pubblica americana da indurre l’amministrazione Reagan a formulare una risposta specifica. Durante la primavera del 1982 fu, infatti, creato un gruppo interdipartimentale ad hoc, l’Arms Control Information Policy Group, con il compito di arginare l’influenza della NWFC sull’opinione pubblica americana e formulare una risposta coerente alle critiche del movimento antinucleare.

Das deutsche Kriegsgefangenenwesen 1939 - 1945

Zusammenfassung: Die vorliegende Untersuchung zum deutschen Kriegsgefangenenwesen (KGW) im Zweiten Weltkrieg schließt eine wichtige Lücke innerhalb der geschichtswissenschaftlichen Forschungen zum Themenkreis der Kriegsgefangenschaft in deutschem Gewahrsam. Bisherige Studien (bis einschließlich 1997) behandeln vor allem sozial- und kulturgeschichtliche Aspekte der Kriegsgefangenen (Kgf.), der Lagergesellschaft und dem Alltag von Soldaten in Kriegsgefangenschaft. Der Verfasser indes legt mit seiner Magisterarbeit erstmals eine Organisations- und Strukturgeschichte des deutschen Kriegsgefangenenwesens von 1939 bis 1945 vor, welche fundamentale Grundlagen der deutschen militärischen Lagerorganisation und Verwaltung dokumentiert. So wird die Entwicklung von den Vorkriegsplanungen bis zum Kriegsende anhand der zentralen Dienststellen herausgearbeitet und im Kontext des Genfer Kriegsgefangenenabkommens von 1929 und völkerrechtlicher Implikationen gewichtet. Hiermit untrennbar verbundene Einflußnahmen nichtmilitärischer Stellen in die Entscheidungsgewalt der Streitkräfte im Heimatkriegsgebiet und in den Wehrmachtbefehlshaberbereichen werden nicht zuletzt auch anhand mehrerer Organigramme veranschaulicht. Zudem dokumentiert und analysiert die Untersuchung die im Kriegsverlauf stetig verschärften Maßnahmen zur Fluchtprävention und der konzertierten Fahndung nach geflohenen Kriegsgefangenen: Die Machterosion des Oberkommandos der Wehrmacht (OKW) zugunsten des Reichsführers-SS, des Reichssicherheitshauptamts und nicht zuletzt der Parteikanzlei der NSDAP wird so augenfällig. Trotz eminenter Schriftgutverluste kann der Verfasser vor allem anhand einer nahezu vollständig erhaltenen Schlüsselquelle die Stellenbesetzung und Organisationsstruktur der mit Kriegsgefangenenfragen befassten Stellen im OKW rekonstruieren. Die Auswertung dieser Sammelmitteilungen / Befehlssammlung für das Kriegsgefangenenwesen sowie an anderer Stelle überlieferter Organisationsbefehle ermöglicht wichtige Änderungen am derzeitigen Forschungsstand. Darüber hinaus beschäftigt sich die vorliegende Untersuchung mit dem Arbeitseinsatz Kriegsgefangener in der deutschen Wirtschaft als in der zweiten Kriegshälfte zentralem Element der Kriegsgefangenschaft. Außerdem wird beleuchtet, welche politischen, (rassen)ideologischen oder reziprok konnotierten Faktoren den Stellenwert gefangener Soldaten unterschiedlicher Nationalität innerhalb der Gefangenenhierarchie im deutschen Kriegsgefangenenwesen bestimmten.

Night Vision Imaging System (NVIS) certification requirements analysis of an Airbus Helicopters H135

The safe operation of nighttime flight missions would be enhanced using Night Vision Imaging Systems (NVIS) equipment. This has been clear to the military since 1970s and to the civil helicopters since 1990s. In these last months, even Italian Emergency Medical Service (EMS) operators require Night Vision Goggles (NVG) devices that therefore amplify the ambient light. In order to fly with this technology, helicopters have to be NVIS-approved. The author have supported a company, to quantify the potentiality of undertaking the certification activity, through a feasibility study. Even before, NVG description and working principles have been done, then specifications analysis about the processes to make a helicopter NVIS-approved has been addressed. The noteworthy difference between military specifications and the civilian ones highlights non-irrevelant lacks in the latter. The activity of NVIS certification could be a good investment because the following targets have been achieved: Reductions of the certification cost, of the operating time and of the number of non-compliance.

Los jóvenes entre la historia y la política : Primeras aproximaciones a las representaciones de la democracia, los gobiernos militares y la participación política de alumnos de la escuela secundaria

El presente trabajo forma parte del proyecto de investigación "Los jóvenes frente a la Historia" dirigido por Luis Cerri y Gonzalo de Amézola, cuyo objeto es abordar el estado actual de la enseñanza y del aprendizaje de la Historia en Argentina, Brasil y Uruguay. El proyecto parte de reconocer como problema la "falta de conocimientos sistemáticos sobre los resultados de la enseñanza de la historia, las características de la conciencia histórica y la cultura política de los jóvenes". El artículo centra su análisis en las respuestas a las preguntas referidas a los gobiernos militares, la democracia y el futuro de los jóvenes, presentes en una encuesta que realizaron en el 2008 alumnos de entre 15 y 16 años de distintas escuelas de la Argentina para acercarnos a sus conocimientos sobre dichos conceptos y al papel de la enseñanza de la Historia en su construcción. Al mismo tiempo se utilizan registros de clases de escuelas secundarias de la ciudad de La Plata para conocer de modo cualitativo las modalidades concretas que asumen las prácticas de la enseñanza en historia en las aulas

La época de los militares : Representaciones, categorías y clasificaciones de ex-obreros de Swift en torno a la violencia política y estatal

En este artículo abordo los modos en que los ex-obreros del frigorífico Swift de Berisso, evocan los acontecimientos más resonantes de la violencia política, paraestatal y estatal en la década de 1970, ligados a la fábrica. Para ello analizo los relatos, construidos con entrevistas en profundidad, de los ex-obreros que en aquellos años fueron militantes de izquierda y de otros con diversas orientaciones políticas y actitudes frente a la organización gremial. Por un lado, exploro las huellas del disciplinamiento social en las vivencias narradas y el desdibujamiento de su significación en algunos casos. Por otro lado, doy cuenta de la heterogeneidad de sentidos atribuidos a dos expresiones nativas que estructuran los relatos y aluden a dos agrupamientos sociales: los que estaban metidos en algo y lo que no estaban metidos en nada. Muestro el carácter difuso de la frontera entre ambos grupos y algunas valoraciones en torno a la igualación de violencias
