Uma cultura de segurança comum na UE através de um programa de formação europeu para as polícias

This master dissertation is to bring a contribution to the reflection on the need to strengthen cross-border cooperation, among the various entities applying the law with a view to building a European security culture through police training. On this basis, it proposes a reflection on the new security paradigm, focused on the demanding and informed security needs by the citizen due to an increasingly transnational crime throughout the different States. This development, coupled with globalization itself, led to the definition of strategies to gear the work of the police in preventing and combating new criminal phenomena such as the European Internal Security Strategy. However, without a true safety culture, which fosters trust among the various actors and ensures a coordinated and uniform action of the police, it will not be easy to achieve the desired effectiveness in protecting the fundamental rights that underpin European integration. Against this background, attempts to explain that the implementation of a common European training program for the police (LETS) is the way forward, with a view to a more effective security in the Union, based on values that embody a genuine European security culture, coveted by all, based on an idea of governance held at different levels of intervention, European, regional and national levels.

The effectiveness of a rotavirus vaccine in preventing hospitalizations and deaths presumably due to acute infectious diarrhea in Brazilian children: a quasi-experimental study

INTRODUCTION: Rotavirus is the main etiologic agent of acute infectious diarrhea in children worldwide. Considering that a rotavirus vaccine (G1P8, strain RIX4414) was added to the Brazilian vaccination schedule in 2006, we aimed to study its effectiveness and safety regarding intestinal intussusception. METHODS: A quasi-experimental trial was performed in which the primary outcome was the number of hospitalizations that were presumably due to acute infectious diarrhea per 100,000 children at risk (0-4 years old). The secondary outcomes included mortality due to acute infectious diarrhea and the intestinal intussusception rates in children in the same age range. We analyzed three scenarios: Health Division XIII of the State of São Paulo (DRS XIII) from 2002 to 2008, the State of São Paulo, and Brazil from 2002 to 2012. RESULTS: The averages of the hospitalization rates for 100,000 children in the pre- and post-vaccination periods were 1,413 and 959, respectively, for DRS XIII (RR=0.67), 312 and 249, respectively, for the State of São Paulo (RR=0.79), and 718 and 576, respectively, for Brazil (RR=0.8). The mortality rate per 100,000 children in the pre- and post-vaccination periods was 2.0 and 1.3, respectively, for DRS XIII (RR=0.66), 5.5 and 2.5, respectively, for the State of São Paulo (RR=0.47), and 15.0 and 8.0, respectively, for Brazil (RR=0.53). The average annual rates of intussusception for 100,000 children in DRS XIII were 28.0 and 22.0 (RR=0.77) in the pre- and post-vaccination periods, respectively. CONCLUSIONS: A monovalent rotavirus vaccine was demonstrated to be effective in preventing the hospitalizations and deaths of children that were presumably due to acute infectious diarrhea, without increasing the risk of intestinal intussusception.

Effectiveness of silver nitrate compared to talc slurry as pleural sclerosing agent in rabbits. Influence of concomitant intrapleural lidocaine

The ideal agent for producing pleurodesis has not been identified. Talc, the most commonly used, poses several problems. Another possibility is silver nitrate, which was widely used in the past. PURPOSE: To determine the influence of the intrapleural instillation of lidocaine in producing a pleurodesis with silver nitrate, to define the effect of lidocaine in the maturation of the collagen fibers, and to confirm that the pleurodesis after silver nitrate is stronger than after talc. METHODS: We studied three groups of 8 rabbits. Two groups received 0.5% silver nitrate; in one we had previously injected 0.5 ml of 2% lidocaine. The third group received 400 mg/kg talc (2 ml). The animals were sacrificed 28 days after the injection, and the pleural spaces were assessed grossly for evidence of pleurodesis and microscopically for evidence of inflammation and fibrosis. The total amount of pleural collagen and the distribution of thick and thin collagen fibers were quantified. Collagen was identified using picrosirius red stain. RESULTS: In the two groups that received silver nitrate (without lidocaine: 3.5 + 03 and with lidocaine: 3.2 + 0.3), the macroscopic pleurodesis (scale 0 -- 4) was significantly (p = 0.001) better than that resulting from talc (1.6 + 0.2). The mean degree of pleural fibrosis induced by silver nitrate (3.5 + 0.2) was significantly (p = 0.004) higher than that induced by talc (1.9 + 0.1). The previous instillation of lidocaine resulted in a tendency for decreased amounts of fibrosis (3.1 + 0.4). The mean amount (10³mm²) of pleural collagen was significantly (p = 0.009) greater in the rabbits that received silver nitrate (116.9 + 22.7) than in those that received talc (10.7 + 3.4). The injection of lidocaine slightly reduced the collagen (80.1 + 30.3). The distribution of collagen fibers did not differ among the groups. CONCLUSION: This rabbit model clearly confirms that intrapleural silver nitrate is more effective than talc for producing pleurodesis. The previous intrapleural instillation of lidocaine results in a decreasing trend in the amount of collagen, but does not change the effectiveness of the pleural fusion or modify the process of collagen maturation.

Oropharyngeal colonization by Haemophilus influenzae in healthy children from Taubaté (São Paulo), prior to the Haemophilus influenzae type b vaccination program in Brazil

Haemophilus influenzae is one of the most important bacterial agents of otitis and sinusitis. H. influenzae type b (Hib) is one of the main causes of meningitis, pneumonia, and septicemia in nonvaccinated children under 6 years of age. The aims of this study were to determine the prevalence of H. influenzae and Hib oropharyngeal colonization prior to the onset of the Hib vaccination program in Brazil in previously healthy children and to assess the susceptibility profile of this microorganism to a selected group of antimicrobials that are used to treat acute respiratory infections. METHOD: Cultures of Haemophilus influenzae were made from oropharynx swabs from 987 children under 6 years of age who were enrolled in 29 day-care centers in Taubaté (a city of São Paulo state, Brazil) between July and December 1998. RESULTS: The prevalence of H. influenzae carriers was 17.4%, and only 5.5% of the strains were beta-lactamase producers. The prevalence of Hib carriers was high, 7.3% on average (range, 0.0 - 33.3%). CONCLUSIONS: The low prevalence of colonization by penicillin-resistant strains indicates that it is not necessary to substitute ampicilin or amoxicilin to effectively treat otitis and sinusitis caused by H. influenzae in Taubaté.

Young adult Brazilian beauty consumers perception of Lancôme and the effectiveness of social media relationhips with local celebrities on their purchase intention

The aim of this research is to evaluate if a premium beauty brand, in this case, Lancôme, can influence positively the purchase intention from Brazilian young adults, between 18 and 29 years old, consumers of beauty products, by initiating a relationship with a local celebrity or “it” girl on social media. This hypothesis has not been tested, and this research is a first attempt of evaluating it. Additionally, the consumer behavior, brand preferences and social media activeness of this age segment in Brazil are further studied as important insights for beauty brands to conquer these consumers. Results did not confirm the positive influence of local celebrities on this age segment’s purchase intention but several suggestions are made for future research to revisit this topic. Furthermore, there is a significant brand love for M.A.C., an international Lancôme competitor, amongst this target, as well as a probable price sensitivity facing premium beauty brands.

A importância da comunicação estratégica na alteração de comportamentos na sociedade : o caso Sociedade Ponto Verde

A comunicação estratégica poderá ser entendida como a comunicação alinhada com a estratégia global de uma organização para alcançar o seu posicionamento estratégico. Ou seja, para alcançar o sucesso, uma organização precisa de ter uma comunicação consistente com a sua identidade e, ao mesmo tempo, adequada ao seu público-alvo e ao tipo de sector onde se insere. Só desta forma consegue conquistar a confiança e fidelidade dos consumidores, essenciais para o alcance dos objectivos. Em relação à alteração comportamentos, é essencial que as empresas costruam uma estratégia de comunicação coerente e consistente, adaptando as mensagens e os públicos-alvo escolhidos. Neste âmbito da alteração de comportamentos, estudou-se neste trabalho a Sociedade Ponto Verde (SPV), uma associação portuguesa sem fins lucrativos, que actua no âmbito da gestão e reciclagem de resíduos de embalagens. Procurou estudar-se a evolução da sua comunicação ao longo dos anos e a forma como adaptou as suas mensagens, de forma a conseguir incutir na sociedade portuguesa a importância do comportamento de reciclagem de resíduos. Neste estudo, procedeu-se a uma análise individualizada de cada uma das campanhas de comunicação da SPV e, posteriormente, aplicou-se um inquérito por questionário, para verificar a eficácia das mesmas campanhas perante o público-alvo. A metodologia utilizada neste trabalho consistiu na distribuição de um inquérito por questionário online, que permitiu recolher uma amostra probabilística por conveniência. Em seguida, recolhidos e tratados os dados referentes às 482 respostas recebidas, utilizou-se o programa SPSS (Stastitical Package for the Social Sciences) para analisar, tratar e discutir os resultados obtidos. Estes resultados demonstraram que, de facto, não houve uma grande percentagem de inquiridos que se lembram das campanhas da SPV. Os resultados são positivos e não desmentem a qualidade e coerência das mensagens, mas a verdade é que a percentagem de indivíduos que não se lembra de algumas campanhas chega a ser elevada (em especial nas campanhas iniciais da organização, quando existia falta de uma estratégia coerente). Justifica-se este facto, em parte, pelo excesso de informação e estímulos a que as pessoas estão sujeitas, pelo que a informação que retêm não fica para sempre, acabando por dar lugar a outras informações. Os indivíduos são inconscientemente selectivos com a informação que processam e guardam, pois não seria possível guardar toda a informação que lhes é transmitida. No que diz respeito à comunicação estratégica que visa alterar uma atitude e, posteriormente, um comportamento, conclui-se que, no geral, o comportamento das pessoas inquiridas aparenta ter sido influenciado pela comunicação da SPV, caso contrário, as respostas afirmativas quanto à reciclagem e de concordância com algumas das afirmações teriam sido inferiores. Ou seja, mesmo reconhecendo o carácter um pouco enviesado da amostra (não deverá ser considerada representativa da população portuguesa), é possível dizer que a estratégia de comunicação da SPV (em especial a partir de 2005) foi eficiente.

Pesquisa experimental para avaliação da eficiência da fibra de aço na resistência à punção de lajes lisas reforçadas simetricamente

O presente artigo é dedicado à avaliação experimental da eficiência do reforço com fibra de aço em termos da resistência à punção de lajes lisa carregadas simetricamente. Para este fim, oito lajes de 2550 x 2550 x 150 mm3 foram ensaiadas até a ruína, onde se investigou a influência do consumo de fibras (0, 60, 75 e 90 kg/m3) e da resistência do concreto (50 e 70 MPa). Duas lajes de referência, sem fibras, uma para cada classe de resistência do concreto, e uma laje para cada consumo de fibra e para cada classe de resistência do concreto compuseram o programa experimental. Todas as lajes foram armadas à flexão com barras de aço (armadura convencional) de forma a garantir a ruína por punção das lajes de referência. O único reforço transversal foi garantido pelas fibras de aço hooked ends com comprimento e diâmetro de 37 e 0,55 mm, respectivamente, e resistência à tração de aproximadamente 1100 MPa. Os resultados revelaram que as fibras de aço são muito eficientes em converter uma ruína frágil por cisalhamento em uma ruína dúctil por flexão, aprimorando ambos, carga de ruptura e deslocamento. Neste artigo o programa experimental é abordado em detalhe e os principais resultados são apresentados e discutidos.

Embedded Through-Section shear strengthening technique using steel and CFRP bars in RC beams of different percentage of existing stirrups

The Embedded Through-Section (ETS) technique is a promising technique for the shear strengthening of existing (RC) elements. According to this technique, holes are drilled through the beam section, and bars of steel or FRP material are introduced into these holes and bonded to the concrete with adhesive materials. An experimental program was carried out with RC T-cross section beams strengthened in shear using the ETS steel bars and ETS CFRP rods. The research is focused on the evaluation of the ETS efficiency on beams with different percentage of existing internal transverse reinforcement (ρsw=0.0%, ρsw=0.1% and ρsw=0.17%). The effectiveness of different ETS strengthening configurations was also investigated. The good bond between the strengthening ETS bars and the surrounding concrete allowed the yield initiation of the ETS steel bars and the attainment of high tensile strains in the ETS CFPR rods, leading to significant increase of shear capacity, whose level was strongly influenced by the inclination of the ETS bars and the percentage of internal transverse reinforcement.

Flexural strengthening of RC beams using hybrid composite plate (HCP): experimental and analytical study

Hybrid Composite Plate (HCP) is a reliable recently proposed retrofitting solution for concrete structures, which is composed of a strain hardening cementitious composite (SHCC) plate reinforced with Carbon Fibre Reinforced Polymer (CFRP). This system benefits from the synergetic advantages of these two composites, namely the high ductility of SHCC and the high tensile strength of CFRPs. In the materialstructural of HCP, the ultra-ductile SHCC plate acts as a suitable medium for stress transfer between CFRP laminates (bonded into the pre-sawn grooves executed on the SHCC plate) and the concrete substrate by means of a connection system made by either chemical anchors, adhesive, or a combination thereof. In comparison with traditional applications of FRP systems, HCP is a retrofitting solution that (i) is less susceptible to the detrimental effect of the lack of strength and soundness of the concrete cover in the strengthening effectiveness; (ii) assures higher durability for the strengthened elements and higher protection to the FRP component in terms of high temperatures and vandalism; and (iii) delays, or even, prevents detachment of concrete substrate. This paper describes the experimental program carried out, and presents and discusses the relevant results obtained on the assessment of the performance of HCP strengthened reinforced concrete (RC) beams subjected to flexural loading. Moreover, an analytical approach to estimate the ultimate flexural capacity of these beams is presented, which was complemented with a numerical strategy for predicting their load-deflection behaviour. By attaching HCP to the beams’ soffit, a significant increase in the flexural capacity at service, at yield initiation of the tension steel bars and at failure of the beams can be achieved, while satisfactory deflection ductility is assured and a high tensile capacity of the CFRP laminates is mobilized. Both analytical and numerical approaches have predicted with satisfactory agreement, the load-deflection response of the reference beam and the strengthened ones tested experimentally.
