This program consists of taking selected shantytowns controlled by criminals organizations back to the State. The strategy of the policy is to dislodge the criminals and then settle a permanent community-oriented police station in the slum. The installation of police units in these slums can generate geographical spillover effects to other regions of the State of Rio de Janeiro. We use the interrupted time series approach proposed by Gonzalez-Navarro (2013) to address effects of a police when there is contagion of the control group and we find that criminal outcomes decrease in areas of UPP and in areas near treated regions. Furthermore, we build a model which allows to perform counterfactuals of this policy and to estimate causal effects in other areas of the State of Rio de Janeiro outside the city.

The 10-valent pneumococcal conjugate vaccine (PCV10) was introduced into the routine infant immunization in Brazil, free of charge, in March 2010. The aim of this study was to evaluate the impact PCV10 vaccination on rates of all cause pneumonia hospitalizations one year and three years after its introduction in Brazil. METHODS: We conducted two interrupted time series analysis studies. The first evaluated only the direct effect of PCV10 vaccination, in five Brazilian cities (Belo Horizonte, Curitiba, Porto Alegre, São Paulo and Recife), and was conducted one year after starting the vaccination. The second study evaluated the direct and indirect impact (individuals not vaccinated) of PCV10 vaccination in Brazil, and was conducted three years after vaccination. We used data from the Brazilian Hospitalization System from 2005-2013. The main outcome was monthly rates of all-cause pneumonia hospitalizations identified by ICD-10 codes J12-J18. We used hospitalization rates for congenital malformations and non-respiratory causes as a comparison groups. The time-series analysis was based on a generalized linear model. Pneumonia rates observed in the pre-vaccination period were used to estimate the hospitalization rates in the post-vaccination period of each study, adjusting for seasonality and secular trends. To estimate the direct (2-23 months of age) and indirect (≥5 years of age) impact of PCV10 vaccination, we calculated the percentage change in hospitalization rates, as the observed divided by the predicted rates of hospitalization in the post-intervention period minus one, with respective 95% CI and p values. The number of all-cause pneumonia hospitalizations averted by vaccination was calculated taking into account the difference between the predicted and observed number in the PCV10 post vaccination period. RESULTS: One year after introduction of PCV10 in Brazil, significant declines in hospitalizations for pneumonia in children aged 2-23 months were noted in Belo Horizonte (28.7%), Curitiba (23.3%), and Recife (27.4%). After three years of the introduction of PCV10, 461,519 pneumonia hospitalizations were averted in Brazil, and a significant decrease in rates of pneumonia hospitalization was observed in unvaccinated individuals aged 5-39 years, ranging from 14.1-17.4% (p<0.05). In contrast, an increased trend in pneumonia hospitalizations (p=0·004) was observed for elderly (≥ 65 years). CONCLUSION: Vaccination with PCV10 in Brazil was associated with reduction of pneumonia hospitalizations in vaccinated individuals. Herd effect was observed in individuals aged 5-39 years after three years of vaccination. Potential reasons for the increased trend in pneumonia hospitalization rates in the elderly should be investigated. / INTRODUÇÃO: As pneumonias contribuem com alta carga de morbimortalidades em todo mundo. No Brasil, a vacina pneumocócica conjugada 10 valente (PCV10) foi introduzida na rotina de imunização da infância em março de 2010. Este estudo teve como objetivo avaliar o impacto da vacinação nas taxas de hospitalizações por pneumonia no Brasil no curto e médio prazo do início da vacinação. METODOLOGIA: Dois estudos de séries temporais interrompidas foram conduzidos. O primeiro avaliou o efeito direto da vacinação em cinco capitais brasileiras (Belo Horizonte, Curitiba, Porto Alegre, São Paulo e Recife) e foi conduzido após um ano de introdução da PCV10 no país. O segundo estudo avaliou o impacto direto e indireto (população não vacinada) da vacinação em todo país e foi conduzido três anos após sua introdução. Os dados de hospitalizações foram obtidos do Sistema de Informações Hospitalares (SIH-SUS) de 2005 a 2013. O desfecho principal foi a taxa mensal de hospitalização por pneumonia definida pelos códigos J12-J18 da CID10. As taxas de hospitalizações por malformações congênitas e causas não respiratórias foram utilizadas como grupos de comparações. A análise de série temporal utilizou um modelo de regressão linear generalizado. As taxas de hospitalizações por pneumonia observadas no período pré-PCV10, ajustadas por tendência secular e sazonalidade, foram utilizadas para estimar as taxas no período pós-PCV10. O impacto da vacinação para cada faixa etária foi calculado como o percentual de mudança nas taxas de hospitalizações, dividindo-se as taxas observadas pelas taxas preditas do período pós PCV10, menos um. Os respectivos IC95% e os valores de p foram apresentados. O número de hospitalizações por pneumonia evitadas após três anos de vacinação foi estimado pela diferença entre os números de hospitalizações por pneumonia preditos e observados no período pós-vacinação. RESULTADOS: Após um ano de introdução da PCV10 no Brasil, observou-se significativo declínio nas taxas de hospitalizações por pneumonia em crianças de 2 a 23 meses em três das cinco capitais estudadas: Belo Horizonte (28,7%), Curitiba (23,3%), e Recife (27,4%). Após três anos da introdução da PCV10, 461.519 hospitalizações por pneumonia foram evitadas no Brasil e um significativo declínio nas taxas de pneumonia foi observado em indivíduos não vacinados de 5 a 39 anos variando de 14,1% a 17,4% (p<0,05). No entanto, observou-se um aumento significativo (9,9%, p=0,004) nas taxas de hospitalizações por pneumonia para idosos ≥65 anos. CONCLUSÕES: A vacinação com a PCV10 foi associada à significativa redução das hospitalizações por pneumonia na infância. Adicionalmente, o estudo evidenciou importante redução das hospitalizações por pneumonia em grupos etários não vacinados, sinalizando efeito indireto conferida pela vacina. A tendência de aumento das hospitalizações por pneumonias em idosos necessita de investigações para elucidação dos fatores envolvidos nesse fenômeno.

As ligas de alumínio são aplicadas em cerca de 70% dos componentes estruturais dos aviões e o processo de fadiga e o modo de falha predominante em estruturas aeronáuticas, para a maioria das quais a presença de concentradores de tensão e inevitável. O comportamento em fadiga e as propriedades mecânicas das ligas de alumínio endurecíveis por precipitação são fortemente influenciadas por parâmetros como tamanho, espaçamento e densidade dos precipitados endurecedores. Neste contexto, pesquisas anteriores tem mostrado que o envelhecimento interrompido (T6I4) pode proporcionar melhores combinações de propriedades mecânicas para estas ligas. O presente trabalho tem como objetivo o estudo das propriedades mecânicas e do comportamento em fadiga de alto ciclo das ligas de alumínio AA6351 e AA7050 nas condições de tratamento térmico convencionais (T6 e T7451, respectivamente) e na condição T6I4, bem como da influência das características microestruturais e do tratamento térmico sobre estas propriedades. Dentro deste contexto, analises de Microscopia Eletrônica de Transmissão (MET) da liga AA6351 mostraram que a condição T6I4 resultou em uma maior densidade de precipitados endurecedores com tamanho heterogêneo, quando comparada com a condição T6. Para esta liga, a condição T6I4 também resultou em menores valores de tensão limite de escoamento, resistência a tração, resistência a fadiga e sensibilidade ao entalhe, com maior ductilidade e tenacidade. Para a liga AA7050, as análises de MET mostraram que a condição T6I4 resulta em uma maior densidade de precipitados endurecedores com menor tamanho, promovendo um melhor impedimento ao movimento de discordâncias durante a deformação por fadiga, quando comparada com a condição T7451. Esta alteração microestrutural proporcionou a condição T6I4 valores de resistência ao escoamento e resistência a tração similares a condição T7451, com maior ductilidade e tenacidade. A resistência a fadiga da condição T6I4 foi similar a condição T7451, entretanto o envelhecimento interrompido resultou em um melhor comportamento em sensibilidade ao entalhe. / Aluminum alloys are applied in approximately 70% of the aircraft structural components and the fatigue process is the dominant failure mode in aeronautical structures, for the most of which, the presence of stress concentrators is unavoidable. The fatigue behavior and the mechanical properties of the age hardenable aluminum alloys are strongly influenced by parameters including the size, spacing and density of strengthening precipitates. Within this context, previous researches have shown that the interrupted ageing (T6I4) could provide an improved combination of mechanical properties for these alloys. This work aims to study the mechanical properties and the high cycle fatigue behavior of AA6351 and AA7050 aluminum alloys in the conventional heat treatment conditions (T6 and T7451, respectively) and in the T6I4 condition, as well as the influence of the microstructural characteristics and of the heat treatment on these properties. Within this context, Transmission Electron Microscopy (TEM) analyzes of the AA6351 alloy showed that T6I4 condition resulted in higher density of hardening precipitates with heterogeneous size compared to T6 condition. For this alloy, the T6I4 condition resulted in lower values of yield stress, ultimate tensile strength, fatigue strength and notch sensitivity, with higher ductility and toughness. For the AA7050 alloy, TEM analyses showed that T6I4 condition presented a higher density of strengthening precipitates with smaller size promoting an improved dislocation pinning effect during the fatigue deformation compared to T7451 condition. This microstructural change provided to T6I4 condition yield stress and ultimate tensile strength similar to T7451, with higher ductility and toughness. The fatigue strength of T6I4 condition was also similar to T7451, however the interrupted ageing provided a better notch sensitivity behavior.

Afin de développer des moyens de protection et de prévention adaptés aux personnes et à leurs activités, ces travaux de thèse contribuent à la compréhension des mécanismes de rupture sous différentes vitesses de chargement. Le comportement de l’os spongieux bovins, non confiné, avec moelle, a été étudié sur 8 niveaux de vitesse de déformation, du régime quasi-statique (10-3/s) au régime dynamique (600/s). Pour cela, des techniques expérimentales de compression interrompue ont été développées. La caractérisation architecturale micro CT pré-compression a ensuite mis en évidence les paramètres de description architecturale pertinents ainsi que le rôle de cette organisation dans le comportement de l’os spongieux sous différents régimes de sollicitation. Associé à l’imagerie micro CT post compression, les faciès de rupture ont été observés. Malgré la base de données expérimentales (127 échantillons), toutes les configurations architecturales présentes chez un être vivant n’ont pas pu être testées. Un premier générateur d’architecture a alors été développé, permettant de créer numériquement des structures osseuses. S’affranchissant du caractère destructif des essais et la dépendance vis à vis des échantillons, cet outil contribue à la compréhension des mécanismes de fracture de l’os spongieux sur une grande plage de vitesses de déformations. Les fondations nécessaires à la validation d’un tel modèle en utilisant la méthode des éléments discrets s’inscrivent enfin comme perspectives immédiates de ces travaux. / In order to develop means of protection and prevention for people and their activities, this thesis manuscript contributes towards understanding failure mechanisms under different loading rates. The behavior of cancellous bovine bone, unconfined, with marrow, has been studied over a range of 8 strain rates, from quasi-static (10-3/s) to dynamic (600/s) regimes. For the latter, specific interrupted compression experimental techniques were developed. The pre-compression micro CT architectural characterization highlighted relevant architectural parameters and the role this organization may have in the behavior of cancellous bone under different regimes. The fracture surfaces of the specimen were observed by post compression micro CT imaging. Despite the large experimental data base (127 samples), all architectural configurations present in individuals could not be tested. A first architectural generator was then developed to digitally create bone structures. Whilst avoiding the destructive nature of the test and the dependence of the samples, this tool contributes to the understanding of the fracture mechanisms of cancellous bone over a large range of strain rates. Finally, the immediate prospects for this work include the validation of the architectural generator using the discrete element method.

[pt] Todos os dias, diversos sistemas são invadidos, muitas pessoas são vítimas de vírus, os mais variados dados são obtidos ilegalmente e muitas empresas ficam de uma hora para outra sem poder operar normalmente. A segurança da informação se ocupa exatamente da proteção dos recursos de informação de empresas e indivíduos. Dentre os diversos assuntos abrangidos pela segurança da informação, o plano de continuidade de negócios (PCN) é o objeto de estudo deste trabalho. Antes confinado à literatura especializada, o PCN ganhou projeção na mídia há pouco mais de dois anos, quando o mundo assistiu perplexo a queda das torres do World Trade Center. O plano de continuidade de negócios tem como objetivo principal evitar, ou reduzir sensivelmente, as perdas das empresas em casos de incidentes que afetem suas operações, além de restaurar suas atividades no espaço de tempo mais breve possível. O objetivo final deste estudo é estabelecer o retrato atual dos planos de continuidade de negócios das empresas brasileiras e propor sugestões para torná-las menos vulneráveis às ameaças internas e externas, sejam novas, antigas ou potenciais. Para atingir o objetivo proposto, foi realizada uma pesquisa com 112 empresas, levantando as percepções de seus executivos, por meio de questionários e entrevistas. A pesquisa demonstra que as empresas não estão preparadas para enfrentar incidentes que possam interromper suas atividades operacionais, estando sujeitas até mesmo à falência. Por fim, é recomendado às empresas que avaliem detalhadamente os riscos aos quais estão submetidas e as conseqüências que os incidentes podem causar. Os impactos podem justificar o investimento em um plano de continuidade de negócios. / [en] Everyday, systems around the world are invaded by hackers, people fall victim to virus attacks, sensitive data are stolen, and firms find their operations screech to a halt. Information Security is responsible for the protection of the information resources of companies and people. The business continuity plan (BCP), one of the many issues that fall under the label of Information Security, is the object of this study. Previously confined to esoteric research journals, BCP gained significant coverage in the mainstream media in the wake of the attacks on the World Trade Center. The primary goal of a business continuity plan is the avoidance, or substantial reduction, of losses that a firm might suffer as a result of security incidents. Put simply, a BCP's goal is to keep firms operating as normal as possible during a disaster and get the firm back to standard operations as quickly as possible. The purpose of this study is to illustrate the current utilization of business continuity plans in Brazilian businesses and suggest how to make them less vulnerable to internal and external threats, regardless of whether they are old, new, or as yet undiscovered. To achieve this objective, 112 companies were selected and the executives could express their perceptions filling the surveys and through interviews. The research demonstrates that firms are not prepared to face incidents which may cause interruptions of their activities. Finally, the research recommends that companies to evaluate carefully the risks involved in their businesses and what consequences the security incidents may cause. The impacts can certainly justify the investments in Business Continuity Plan.

Background Gabapentinoids (gabapentin and pregabalin), a class of FDA-approved antiepileptic medications with expanded indications for certain neuropathic pain conditions, have been prescribed off-label for almost all types of pain in the US opioid epidemic. Methods We used IBM® MarketScan® Research Databases (2015-2018) and collected primary data. In Aim 1, we described the geographic variation in gabapentinoids and opioids for pain by US state and metropolitan statistical area (MSA). In Aim 2, we implemented a controlled multiple baseline interrupted time series analysis and assessed the impact of including gabapentin in states’ prescription drug monitoring programs (PDMP) and listing gabapentin as a Schedule V controlled substance. In Aim 3, we developed an algorithm to identify potential gabapentin misuse and/or abuse in administrative claims data. Results The pattern of the geographic variation in gabapentinoids was similar to that of opioids across states and MSAs. Including gabapentin in PDMPs and Schedule V controlled ABSTRACT viii substance classification were effective in curbing the growth of gabapentin use and reducing opioid-related adverse events. Our algorithm identified approximately one in six patients with gabapentin use as having potentially misused and/or abused gabapentin. Multiple comorbidities and drug use were associated with gabapentin misuse and/or abuse. Conclusions Gabapentinoids may have been widely used as alternative or adjuvant analgesics to opioids for pain across the US. Policy makers should consider including gabapentin in proactive PDMPs and scheduling of gabapentin. Monitoring requirements and individualized safety measures should be put in place for patients who potentially misuse and/or abuse gabapentin.

Detta arbete letar efter vilka faktorer som får elever att söka sig till samt slutföra sinNationella Idrottsutbildningar (Niu) inom sin valda idrott. Detta kan sedan användas inomföreningar för att få spelare att stanna kvar inom både föreningen och i vissa fall idrotten. Idenna differentiella studie användes en tvärsnittsdesign och data samlades in genom en enkätsom eleverna fick fylla i. De som deltog i enkäten var 56 elever i åldrarna 16-19 år (årskurs1-3 i gymnasiet), både kvinnor och män, eleverna spelade antingen handboll eller innebandy.Data analyserades med oberoende T-test och deskriptiv statistik. T-tester visade på att detfanns en statistiskt signifikant skillnad mellan årskurserna i hur viktig gemenskapen tillträningsgruppen är. Där skattade årskurs 3 högre än årskurs 1. T-test visade ocksåsignifikanta skillnader mellan könen i två variabler. Variablerna tränarnas inflytande ochvikten av att få utöva sin idrott på skoltid och huruvida dessa påverkade deras vilja att sökasig till Niu. För kvinnor verkade tränaren spela större roll och för män så var det viktigare attfå utöva sin idrott på skoltid.Saker som kan missas av denna studie samt potentiella problem är storleken på grupperna.Storleken på grupperna är inte så stor, de flesta har liknande bakgrund så väl som att det ärskolelever som svarat på enkäterna i slutet av en lektion vilket kan leda till att svaren inte ärde mest genomtänkta så väl som lika varandra.För framtida forskning, att kombinera enkäter med intervjuer kan ge både bättre resultat såväl som en djupare insyn i vad samt hur det kommer sig vad eleverna anser vara viktigt fördem att välja Niu och slutföra sin utbildning.Nyckelord: elitidrottsgymnasium, studieavbrott, Niu, handboll, innebandy. / This work seeks to find factors leading to students applying for as well as finishing theirNational sports education (Niu) in their chosen sport. This can later be used within clubs tokeep players within the club or in some cases the sport. In this differential study a crosssectional design was used and data collected through a survey filled in by the students. The56 participants were between the ages of 16-19 years old (year 1-3 in the gymnasium), bothwomen and men, the students played either handball or floorball.The data was analyzed by using independent T-tests and descriptive statistics. The T-testsshowed there was a significant difference between the groups year 1 and year 3 in howimportant the connection to the group is. Where year 3 ranked higher than year 1. The T-testalso showed significant differences between the genders in two variables. The variablesImportance of coach and Importance of practicing their chosen sport during school hours,which impact these had on their will to go to Niu. For women the coach seemed to have ahigher importance and for men getting to practice their chosen sport during school hours wasof a higher importance.A limitation with this study is the sample size of the groups. The sample size is not that large,most are from a similar background as well as it being school students answering the surveysat the end of a class which could lead to the answers not being the most thought-out answersas well similar to each other.4For future research, combining survey answers with interviews might yield better results anda deeper understanding to what as well as how come the students find as important factors fortheir choice to go to Niu and complete their education.Keywords: sport high school, interrupted studies, Niu, handball, floorball.

Contexte et objectifs. En 1995, le gouvernement canadien a promulgué la Loi C-68, rendant ainsi obligatoire l’enregistrement de toutes les armes à feu et affermissant les vérifications auprès des futurs propriétaires. Faute de preuves scientifiques crédibles, le potentiel de cette loi à prévenir les homicides est présentement remis en question. Tout en surmontant les biais potentiels retrouvés dans les évaluations antérieures, l’objectif de ce mémoire est d’évaluer l’effet de la Loi C-68 sur les homicides au Québec entre 1974 et 2006. Méthodologie. L’effet de la Loi C-68 est évalué à l’aide d’une analyse des bornes extrêmes. Les effets immédiats et graduels de la Loi sont évalués à l’aide de 372 équations. Brièvement, il s’agit d’analyses de séries chronologiques interrompues où toutes les combinaisons de variables indépendantes sont envisagées afin d’éviter les biais relatifs à une spécification arbitraire des modèles. Résultats. L’introduction de la Loi C-68 est associée à une baisse graduelle des homicides commis à l’aide d’armes longues (carabines et fusils de chasse), sans qu’aucun déplacement tactique ne soit observé. Les homicides commis par des armes à feu à autorisation restreinte ou prohibées semblent influencés par des facteurs différents. Conclusion. Les résultats suggèrent que le contrôle des armes à feu est une mesure efficace pour prévenir les homicides. L’absence de déplacement tactique suggère également que l’arme à feu constitue un important facilitateur et que les homicides ne sont pas tous prémédités. D’autres études sont toutefois nécessaires pour clairement identifier les mécanismes de la Loi responsables de la baisse des homicides. / Context and objectives. Laws with extensive background checks and making mandatory the registration of all guns have been adopted by some governments to prevent firearms-related homicides. On the other hand, methodological flaws found in previous evaluations question the potential of such laws to prevent gun homicides. By taking into account previous limitations, the main objective of this study is to estimate the effect of Bill C-68 on homicides committed in the Province of Quebec, Canada, between 1974 and 2006. Methodology. Using extreme bounds analysis, we assess the effect of Bill C-68 on homicides. Estimates of the immediate and gradual effects of the law are based on a total of 372 equations. More precisely, interrupted time series analyses were conducted, using all possible variable combinations, in order to overcome biases related to model specification. Results. We found that Bill C-68 is associated with a significant and gradual decline in homicides committed with a long gun (either a riffle or a shotgun). The substitution effects are not robust with respect to different model specifications. Patterns observed in homicides involving restricted or prohibited firearms suggest that they are influenced by different factors, not considered in our analyses. Conclusion. Results suggest that enhanced firearm control laws are an effective tool to prevent homicides. The lack of tactical displacement supports the concept of firearm as a crime facilitator and suggests that all homicides are not carefully planned. Other studies are however needed to pinpoint law provisions accountable for the decrease in homicides.

Contexte et objectifs. Depuis plusieurs années, la criminalité économique génère des coûts économiques et sociaux importants. Plusieurs acteurs, dont les entreprises privées, se sont mobilisés pour lutter contre ce phénomène. La fraude par carte de débit est un crime économique en expansion contre lequel plusieurs organisations ont entrepris des actions. L’objectif de ce mémoire est d’améliorer les connaissances sur les effets des mesures de prévention situationnelle appliquées dans les succursales d’un commerce de détail et leur impact sur le processus décisionnel des délinquants impliquées dans le clonage de cartes de débit. Méthodologie. Les effets des mesures de prévention mises en place sont évalués à l’aide d’analyses de séries chronologiques interrompues. En complément des analyses statistiques, des entrevues et une analyse documentaire sont effectuées. Les entrevues sont réalisées avec des enquêteurs du service de sécurité de l’entreprise de commerce de détail. L’analyse documentaire est basée sur les rapports d’événement ouverts lors des fraudes par carte de débit. Résultats. Les mesures de prévention ont produit différents effets. Selon la mesure, il fut possible de constater soit une hausse ou une baisse dans le nombre de délits commis. Certaines mesures ont, en outre, provoqué un déplacement spatial, un déplacement dans le choix de la cible, un déplacement dans le type de crime commis et, finalement, un déplacement tactique. Conclusion. Les résultats suggèrent que les mesures de prévention adoptées ont empêché la réalisation des délits associés à la fraude par carte de débit. Par contre, la présence de plusieurs formes de déplacement indique que les fraudeurs se sont adaptés aux mesures de prévention. Afin de documenter adéquatement cette forme de crime et les déplacements générés, d’autres études s’avèrent nécessaires. / Context and objectives. Each year, economic crimes generate important economic and social losses. Many enterprises, including private enterprises, collaborated and introduced initiatives in order to combat this criminality. Fraud using automated payment cards is a crime in full expansion against which many organizations have taken actions. The objective of this dissertation is, on one hand, to improve the knowledge on the impact of preventive measures implemented in the branches of a retailer and, on the other hand, to estimate their impact on the criminal decision-making process. Methodology. The effect of preventive measures is assessed through interrupted time series analysis. In addition, members the retailer security staff were interviewed and a review of event reports associated with debit card fraud was performed. Results. The preventive measures were associated to various results. Depending on the preventive measure, one can observe either an increase or a decrease in the number of crimes performed. It is also observed that some measures have resulted in tactical and spatial displacements. Some offenders have also started to commit other types of crimes. Conclusion. The results suggest that the preventive measures implemented had a significant preventive effect on debit card crimes. However, the presence of many types of displacement shows that the offenders have adjusted to those preventive measures. In order to properly document this type of crime and associated displacements, additional studies are necessary.
