Full textAbstract:
Increased DHS mission requirements in a post 911 operating environment and federal mandates requiring measurable results dictate commanders of USCG Cutters and the chain of command employ the most efficient management mechanisms to best utilize scarce resources. United States Coast Guard Cutters have been challenged in a multi-mission environment to meet requirements including search and rescue, law enforcement, fisheries management, recreational boating safety, hurricane avoidance and response, and homeland security missions. The Commanding officers of U.S. Coast Guard Cutters are consummate process owners that require the most efficient and dynamic management model to best meet internal and external customers in an ever-changing operating environment.

The Systems-Theoretic Accident Model (STAMP) developed by MIT's Dr. Nancy Leveson was applied in this thesis to a ship navigation control system used on U.S. Coast Guard buoy tenders. The legacy system installed on the Service's 16 sea-going buoy tenders experienced numerous incidents that had potential to be hazardous to the ships and their crews. Faced with the dual needs of ensuring safety of mission execution and restoring confidence in the overall ship control system, yet faced with a limited budget, Coast Guard decision-makers elected to conduct a partial recapitalization of the system's hardware and software. This thesis explores the application of system safety methods to analyze the legacy system on the seagoing buoy tenders. An accident analysis of a particular incident was conducted using STAMP methodologies, and its results were compared/contrasted with the results of a more traditional root cause failure analysis that was contracted by the Coast Guard following the incident. Several added insights pertaining to system safety and process improvement were obtained by using STAMP. Additionally, a hazard analysis was performed on the control system using STAMP techniques. This hazard analysis yielded 92 specific design requirements that may be incorporated into future system upgrades on these or similar vessels. The thesis concludes that STAMP methodologies are appropriate to generate actionable recommendations for future control system upgrades on U.S. Coast Guard buoy tenders. It also concludes that STAMP techniques may lead to safer controls in the greater hierarchical control structure for shipboard buoy tending operations. Finally, suggestions are made for future research/application of STAMP principles in the Coast Guard's management of operational safety, asset acquisition, and cybersecurity.

"Model for Predicting Resistance and Running Attitude of High-Speed Craft Equipped with Interceptors : A comparative study including validation on Swedish Coast Guard patrol boat KBV 315." Thesis, KTH, Skolan för teknikvetenskap (SCI), 2016. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-193664.
Full textAbstract:
The purpose of this bachelor thesis is to build a model for predicting resistance and running attitude of high-speed craft equipped with interceptors. The thesis examines the profits gained in terms of economic, comfort and environmental investment. The current study aims to illustrate the impact of interceptors in planing ships, by simulating a steady state model of the dynamic running position. Thus, data regarding trim and drag will be generated. The model is based on previously made studies by Savitsky, Dawson and Blount, Brown and Steen. Extrapolation of the results is realized with the Swedish Coast Guard boat KBV 315 to validate interceptor benefits with the Coast Guard patrol craft. Two different models are presented and the results show a fuel consumption reduction of 8-13%, for the speed range of 15-24 knots, and maximum trim decrease of 1.7˚ for KBV 315. It is concluded that interceptors have a great potential of increasing both comfort (in terms of trim) and efficiency of high-speeds crafts. The provided models can be used as an estimation tool of the outcome before issuing an installing project.

Full textAbstract:
Among the four valves of the heart, the aortic valve (AV) is frequently affected by disease. When progressive dilatation of the valve produces a leak when the valve should close (regurgitation), repair may be possible. AV repair is a desirable option because, contrary to AV replace-ment using a prosthesis, it does not require life-long anticoagulation treatment, and retains the original tissues that naturally combat structural degradation. All the AV repair procedures developed by cardiac surgeons require a good stabilization of the ventriculo-aortic junction (VAJ) diameter, through annuloplasty or reimplantation, for long-term success. In the present work, a preliminary design for a new type of annuloplasty ring is proposed that surgeons could tailor to the each valve’s shape and suture inside the VAJ. The design consists in wrapping a commonly available surgical biomaterial into a ring of controlled radial flexibility. For sizing and material selection, several models of increasing complexity were created to account for the anisotropic, hyperelastic nature of all the materials involved. First, an analytical model was programmed in MATLAB to assess the radial flexibility of annuloplasty rings formed with different biomaterials and select those that could match the physiological VAJ radial flexibility between systolic and diastolic pressures. The same program was also used to reproduce the experimental radial and longitudinal stretches of the human VAJ from 0 to 140 mmHg pressures. The analytical models were used to calibrate the parameters of independent finite element (FE) models of the VAJ and ring. Finally, the FE approach was extended to simulate the ring after suturing inside the VAJ, to determine the radial flexibility of the assembly under pulsatile pressure. Supple Peri-Guard® bo-vine pericardium patches used in transverse orientation emerged as the best currently available material option for the proposed ring, although a material providing more physiological radial flexibility would be desirable.

Full textAbstract:
L'agent causal du flétrissement bactérien, Ralstonia solanacearum est l'une des bactéries pathogènes qui cause le plus de ravages sur les cultures d'intérêt économique. Le gène de Résistance à Ralstonia solanacearum (RRS1-R) isolé à partir de l'écotype résistant Nd-1 d'A. Thaliana, code une protéine à structure modulaire atypique. Elle combine en effet, un domaine TIR-NBS-LRR, commun à de nombreuses protéines de résistance, et un domaine d'activation transcriptionnelle WRKY, caractéristique d'une famille de facteurs de transcription végétaux. PopP2, le gène d'avirulence correspondant à RRS1-R, code une protéine appartenant à la famille d'effecteurs YopJ/AvrRxv. Les deux partenaires R/Avr interagissent physiquement dans le noyau de la cellule végétale. Cependant, cette interaction physique n'exclue pas l'intervention d'autres composantes végétales impliquées dans l'activation de la résistance. Selon le modèle de garde, les protéines d'avirulence sont des facteurs de virulence capables de modifier des protéines végétales cibles dans le but de détourner la physiologie de la plante en faveur de la bactérie. Les protéines de résistance joueraient alors un rôle de gardien en détectant les modifications des protéines ciblées, et activer les mécanismes de résistance en aval. Dans ce contexte, la recherche d'interacteurs de PopP2 a été entreprise par le criblage double hybride d'une banque d'ADNc d'A. Thaliana. Parmi plusieurs candidats, nous avons identifié et caractérisé RD19, une protéase à cystéine de la famille de la papaïne. Par une approche de génétique inverse, nous avons montré que cette protéase à cystéine est impliquée dans l'établissement de la résistance d'A. Thaliana à R. Solanacearum. Exprimée transitoirement chez N. Benthamiana, RD19 fusionnée à la protéine fluorescente YFP (Yellow Fluorescent Protein) est détectée dans des petits compartiments mobiles adressés à la vacuole. De manière surprenante, lorsque RD19 est coexprimée avec PopP2, elle est également détectée au niveau du noyau. .Bacterial wilt caused by the phytopathogenic bacterium Ralstonia solanacearum is one of the most important plant diseases worldwide. The RRS1-R gene (Résistance to Ralstonia solanacearum) confers broad spectrum resistance to several strains of this pathogen. It encodes an atypical resistance protein which combines the TIR-NBS-LRR domains found in several R proteins and a WRKY motif characteristic of some plant transcriptional factors. PopP2, a Ralstonia solanacearum type III effector which belongs to the YopJ/AvrRxv protein family, is the avirulence protein recognized by RRS1-R. Both partners can physically interact in the plant nucleus. Nevertheless, this physical interaction doesn't exclude the role of other plant components in the activation of resistance. According to the "guard model", avirulence proteins are virulence factors which manipulate plant proteins to favour microbial development. Resistance proteins would then act as guards of modified plant targets and activate resistance. In this context, search for PopP2 interactors has been initiated by a Yeast-2-Hybrid screening of an Arabidopsis cDNA library. Among several candidates, we identified and characterized RD19, a papain-like Cysteine protease. Using a reverse genetic approach, we showed that RD19 is involved in the establishment of resistance of A. Thaliana to R. Solanacearum. Transient expression in N. Benthamiana showed that, when fused to the fluorescent protein YFP (Yellow Fluorescent Protein), RD19 is detected in small mobile compartments targeted to the vacuole. Interestingly, when coexpressed with PopP2, RD19 is also detected in plant nuclei. .

Os recursos humanos são, hoje, o fator essencial nas organizações. Tendo em conta
o contexto atual, cada vez mais competitivo e volátil, é essencial que as organizações desenvolvam políticas de gestão e avaliação dos seus recursos humanos, de forma a desenvolver e motivar os seus colaboradores.
É neste contexto que surge o presente trabalho de investigação, subordinado ao tema: “Avaliação de Desempenho: contributos para um modelo de avaliação”.
O objetivo geral deste trabalho de investigação é determinar uma possível forma de melhorar o processo de avaliação de desempenho dos Oficiais da Guarda Nacional Republicana (GNR), tendo como objetivos específicos: identificar as dificuldades da implementação do Sistema Integrado de Gestão e Avaliação do Desempenho na
Administração Pública (SIADAP) à GNR, determinar a perceção dos Oficiais da GNR relativamente à implementação de um sistema de avaliação de desempenho baseado no SIADAP, determinar a perceção dos Oficiais da GNR relativamente à implementação de um
sistema de avaliação de desempenho por objetivos, perceber se um sistema de avaliação de desempenho baseado em competências é adequado para avaliar o desempenho dos Oficiais da GNR e identificar as competências mais adequadas para avaliar o desempenho dos oficiais da GNR.
Este trabalho de investigação encontra-se dividido em duas partes, a parte teórica e a
parte prática. Na parte teórica, é efetuada a pesquisa bibliográfica, que teve particular incidência sobre as obras de referência e estudos relacionados com o tema, de forma a poder sustentar o trabalho de campo. A parte prática, teve por base a recolha de dados e informações através da aplicação de inquéritos por questionário e entrevistas, cuja análise e discussão permitiu dar resposta às perguntas de partida/hipóteses, bem como extrair algumas reflexões relativas ao tema.
Conclui-se com este trabalho que a GNR, possui um sistema de avaliação
desatualizado e que não permite avaliar corretamente o desempenho dos Oficiais. Desta forma, deve optar-se pela implementação do SIADAP adaptada à realidade da Guarda, ou em alternativa proceder à implementação de um sistema de avaliação de desempenho que
permita avaliar simultaneamente competências e objetivos.Abstract Human resources are, today, an essential factor in organizations. Taking into account the current context, which is increasingly more competitive and more volatile, it is essential that organizations develop policies for management and evaluation of their human resources in order to motivate their employees. It is in this context that the present research emerges, under the title: "Performance Evaluation: contributions to an evaluation model." The overall goal of this research is to determine a possible way to improve the process of evaluating the performance of officers of the National Guard (GNR). The study has the following goals: to identify the difficulties in implementing the Integrated Management System and Performance Evaluation of the Public Administration (SIADAP) to the GNR; to determine the perception of GNR officers regarding the implementation of a system of performance evaluation based on SIADAP; to determine the perception of GNR officers regarding the implementation of a system of performance evaluation by objectives; to determinate whether if a system of performance evaluation based on skills is appropriate to evaluate the performance of GNR officers; and to identify the most appropriate ways to evaluate the performance of GNR officers. This research is divided into two main sections, a theoretical and a practical section. The theoretical section undertakes a literature review with a particular focus on reference works and studies related to the topic, in order to be able to validate the field work. The practical section, was based on the collection of data and information through the use of questionnaire surveys and interviews, analysis and discussion which helped answer the questions beginning/hypotheses and allowed us to draw some reflections on the subject. In conclusion, the GNR has an evaluation system outdated and is not able to evaluate properly the performance of the GNR officers. Therefore, the implementation of SIADAP should be done but adapted to the reality of the GNR institution, or alternatively proceed with the implementation of a system of performance evaluation to assess both skills and goals.

No seio de qualquer organização deverá sempre existir uma estrutura ou mecanismos que exerçam o controlo interno. Sem estes não haverá forma de avaliar se existem desvios ao que é esperado, planeado e exigido aos seus subordinados. É muito importante para uma força de segurança, como a GNR, pois a sua actuação passa por assegurar e respeitar os direitos, liberdades e garantias dos cidadãos.
O presente estudo pretende verificar se os Comandantes, aos vários escalões do Comando
Territorial, têm os instrumentos necessários para efectuar o controlo interno da actividade policial.
O Trabalho de Investigação Aplicada, no seu enquadramento teórico, identifica os conceitos mais relevantes para a compreensão do trabalho, baseando-se na análise bibliográfica de autores de referência.
No trabalho de campo foram aplicadas entrevistas a comandantes, dos vários escalões do Comando Territorial, dos Comandos Territoriais de Lisboa, Santarém, Aveiro, Porto e Viana do Castelo. O tipo de amostragem foi a amostragem por conveniência.
Verificou-se que os instrumentos de controlo da actividade policial são meios imprescindíveis para a acção de comando. Os instrumentos de controlo assumem cada vez mais relevância no desenvolvimento da actividade policial das unidades Territoriais. Os instrumentos de controlo da actividade policial são elementos determinantes na aplicação do controlo. Sem um controlo adequado não seria possível avaliar a actividade policial e introduzir as correcções necessárias, de forma a melhorar o desempenho dos militares.
Pode assim concluir-se que os Comandantes, aos vários escalões do Comando Territorial,
têm os instrumentos necessários para efectuar o controlo interno da actividade policial, sendo estes eficazes quanto ao seu resultado. Contudo há a necessidade de potencializar e rentabilizar os instrumentos de controlo da actividade policial existentes.Abstract In any organization should always be a structure or a combination of mechanisms to exercise internal control. Without these there is no way to assess if there are deviations from what is expected, planned and required of their subordinates. That is very important for a police organization, such as GNR, because its action it goes through ensure and respect rights, freedom and guarantees of citizens. This study aims to verify if the local Commanders, at the various levels of the Territorial Command, have the necessary tools to perform the internal control of police activity. The applied research in its theoretical framework identifies the most important concepts for understanding the work, based on literature review of referenced authors. During the fieldwork, interviews were made to the Commanders of the various levels of the Territorial Command, Territorial Commands of Lisboa, Santarém, Aveiro, Porto and Viana do Castelo. The type of sampling was convenience sampling. It was concluded that the control instruments of police activity are indispensable means to the command action. Control instruments are becoming increasingly important in the development of police activity in Territorial Commands. The control instruments of police activity are key elements in the application of control. Without adequate control it would not be possible to evaluate the police activity and introduce the necessary corrections in order to improve the performance of the military. It can thus be concluded that the Commanders, at the various levels of the Territorial Command, have the necessary tools to perform the internal control of the police activity, which are effective in their result. However there is a need to leverage and monetize the existing control instruments of the police activity.

Full textAbstract:
Cette thèse porte sur l'optimisation des performances des systèmes de transmission multimédias MIMO-OFDM prenant conjointement en compte les imperfections de l'amplificateur de puissance et les distorsions du canal. Les fluctuations d'amplitude des signaux OFDM, caractérisées par un PAPR élevé, rendent la transmission vulnérable à la non-linéarité de l'amplificateur de puissance. On propose dans un premier temps une méthode permettant d'améliorer les performances de la méthode Tone Reservation en termes de gain de réduction du PAPR et de rapidité de convergence, en associant les échantillons de l'Intervalle de Garde aux Sous-Porteuses Nulles. Les simulations en présence d'un amplificateur de puissance à effets mémoire et d'un canal radio basé sur un modèle de propagation réaliste montrent que la méthode proposée offre de bonnes performances tout en respectant les spécifications fréquentielles, dans le cadre du standard IEEE 802.11a. Dans un second temps, on propose d'étudier l'impact de la non-linéarité dans un système MIMO-OFDM précodé dédié à la transmission d'images JPWL, respectant la norme IEEE 802.11n. On montre que la non-linéarité affecte la robustesse de transmission contre les erreurs de transmission et dégrade considérablement la qualité visuelle des images reçues. Enfin, on propose une stratégie de précodage originale prenant conjointement en compte l'amplificateur de puissance, le canal de transmission et le contenu de l'image à transmettre. Cette stratégie alloue successivement la puissance sur les sous-canaux SISO issus de la décomposition du canal MIMO afin de maximiser la qualité visuelle des images reçues tout en réduisant la puissance totale d'émission. Les résultats de simulation montrent que cette nouvelle stratégie qui considère un amplificateur et un canal réalistes, permet de garantir la robustesse de transmission et d'améliorer la qualité visuelle des images reçuesThis thesis focuses on the optimization of multimedia transmissions in MIMO-OFDM systems by jointly taking into account the power amplifier non-linearity and the wireless channel distortions. The OFDM modulation generates a high peak fluctuation, measured by the PAPR, which is affected by the RF non-linearity such as the power amplifier, reducing the transmission quality. We first propose a new method to improve the Tone Reservation method performances in terms of PAPR reduction gain and convergence speed, by including the samples of the Guard Interval Signal in the optimization algorithm. Simulations results using a power amplifier model with memory effects and a radio channel based on a realistic propagation model show that the new method offers the better performances, while respecting the IEEE 802.11a spectrum mask. Secondly, we propose to study the impact of power amplifier nonlinearity on the transmission of scalable image contents over a precoded Closed-Loop MIMO-OFDM system. The simulations in a realistic context, under the standard IEEE 802.11n standard show that the RF non-linearity affects the robustness against transmission errors and highly degrades the visual quality of the received JPWL images. Finally, we propose a new precoding strategy which jointly takes into account the power amplifier, the radio channel and the image content to be transmitted. This strategy successively allocates power between the SISO sub-channels obtained from the MIMO channel decomposition in order to maximize the visual quality of the received images, while reducing the total output power. Simulations with a realistic power amplifier model, associated with a realistic channel model show that this new strategy ensures a robust transmission and improves the visual quality of the received images

Chegámos à conclusão que os normativos que regulam a prática do tiro no serviço territorial necessitam de ser adaptados e tornados exequíveis, a fim de serem passíveis de serem cumpridas as suas disposições em todo o dispositivo. Concluiu-se ainda que
existem métodos que podem contribuir para a inovação da qualidade da formação prestada aos militares da GNR.

The methodology of the theoretical part is based on the analysis of the existing documents, while for the practical part a hypothetical-deductive method was used, along with the inquisitorial method, through interviews and questionnaire surveys. Through the interviews and surveys joint analysis results it was possible to achieve several points of view from the stakeholders in study. We came to the conclusion that the legislation which regulates the shooting practice in the operational service needs to be adapted and made more feasible, in order to be complied with its provisions. It was also concluded that there are methods t hat can contribute to innovate the quality of formation provided to the GNR military police officers. It is proposed an adequacy of the legislation which regulates the shooting practice, as well as more availability of logistical and financial resources, in order to provide the GNR military police officers with a higher quality formation.

Dissertação de Mestrado Integrado em Medicina VeterináriaA doença periodontal (DP) é uma das doenças mais frequentes na espécie canina, afetando cerca de 80-85% destes animais. Esta doença, de etiologia multifatorial, inicia-se com o desenvolvimento, na superfície do dente, de placa bacteriana, um biofilme composto maioritariamente por bactérias contidas numa matriz de polissacáridos extracelulares, com o potencial de inibir a ação antimicrobiana e as defesas naturais do hospedeiro. Os processos de agregação bacteriana constituem um fenómeno bastante importante na formação de biofilme ao contribuir para a interação bacteriana durante a evolução da DP. O principal objetivo do controlo da DP é controlar a formação da placa bacteriana. Estudos realizados com isolados de Enterococcus faecalis, obtidos a partir de amostras da cavidade oral canina, demonstraram atividade antimicrobiana de um gel de goma de guar suplementado com nisina (biogel de nisina) contra esta espécie bacteriana, demonstrando a sua potencial eficácia para o controlo da DP canina. Este estudo teve como objetivos o desenvolvimento de um modelo de biofilme polimicrobiano in vitro, que seja representativo da placa bacteriana presente na cavidade oral canina, e a avaliação do potencial inibitório e de erradicação do biogel de nisina relativamente ao biofilme polimicrobiano estabelecido. As espécies bacterianas incluídas foram: Porphyromonas cangingivalis, Neisseria zoodegmatis, Corynebacterium canis, Peptostreptococcus canis e E. faecalis. Durante a primeira fase deste projeto, foi avaliada a capacidade de agregação entre os cinco isolados bacterianos. Todos os isolados demonstraram capacidade de agregação, revelando o seu potencial para a formação de biofilmes polimicrobianos. De seguida, promoveu-se a formação de um biofilme polimicrobiano constituído pelas cinco espécies bacterianas em estudo. A presença das espécies bacterianas no biofilme estabelecido in vitro foi confirmada através da sua observação direta ao microscópio de fluorescência após aplicação da técnica de “Fluorescent In Situ Hybridization”. Os resultados da avaliação do potencial inibitório e de erradicação do biogel de nisina revelaram um valor de concentração mínima inibitória de biofilme de 25 μg/mL e um valor de concentração mínima de erradicação de biofilme superior a 100 μg/mL. Ambos os valores correspondem a concentrações de nisina abaixo do limite da dose diária aceitável definida pela Organização Mundial de Saúde, que corresponde a 0 – 2 mg/Kg. Este estudo demonstrou mais uma vez a eficácia do biogel de nisina para a inibição de biofilmes polmicrobianos confirmando o potencial para a sua utilização no controlo da DP canina.
ABSTRACT - Development of an in vitro model for the evaluation of an antimicrobial biogel with potential for the control of canine periodontal disease - Periodontal disease (PD) is one of the most common diseases in dogs, affecting around 80 to 85% of the canine population. It refers to a group of conditions caused by the development of a dental plaque in the tooth surface. The dental plaque is characterized by a microbial biofilm formed by a multi-species community of microorganisms enclosed in a self-producing extracellular matrix, which protects bacteria from the host immune system and reduces the action of antimicrobial therapy. It is a well-known fact that aggregation is a specific process that plays an important role in the bacterial interactions during biofilm formation. This process contributes to the changes on bacterial composition of the biofilm during the progression of PD. Periodontal therapy aims to control the formation of bacterial plaque. Previous studies have demonstrated that, when incorporated within a guar-gum biogel (nisin-biogel), antimicrobial peptide nisin can inhibit and eradicate mono-species biofilms formed by canine oral enterococci, rendering it a potential agent for PD control. The main objectives of this project were to establish a five-species biofilm model aiming to simulate dental biofilms from dogs with PD and to use the established model to evaluate the inhibitory potential of the nisin-biogel, previously developed by our research team. The bacterial species included were: Porphyromonas cangingivalis, Neisseria zoodegmatis, Corynebacterium canis, Peptostreptococcus canis and Enterococcus faecalis. During the first task, aggregation rates between all the isolates were calculated two by two and individually. All the isolates showed aggregation ability after either a 2h or 24h incubation, showing their potential to form multi-species biofilms. Later, a five-species biofilm model was successfully established and the presence of the five bacterial species was confirmed by Fluorescent In Situ Hybridization using specific probes. The susceptibility of the multi-species biofilm to the nisin-biogel was evaluated by determination of the Minimum Biofilm Inhibitory Concentration (MBIC) and of the Minimum Biofilm Eradication Concentration (MBEC). The nisin-biogel presented inhibitory activity against the polymicrobial biofilm, with a MBIC value of 25 μg/mL and a MBEC value > 100 μg/mL, both corresponding to nisin dosages lower than the acceptable daily intake, 0 – 2 mg/Kg, set by the World Health Organization. This study demonstrated that the nisin-biogel developed by our research team can inhibit the formation of multi-species biofilms, reinforcing its potential to control canine PD.

O futebol é um fenómeno desportivo que faz deslocar milhares de pessoas, como
foi o caso da Final da Taça da Liga de 2009/2010, por esse motivo foi proposto avaliar qual foi o impacto do modelo de policiamento implementado pela GNR sobre os cidadãos neste espetáculo desportivo de futebol.
Esta investigação foi integrada num est udo de caso para conhecer os meios
aplicados pela GNR e todos os procedimentos realizados no policiamento e segurança nos
espetáculos desportivos de futebol. Principalmente, tomar conhecimento de qual foi o modelo adotado, qual foi a influência do modelo e nquanto medida de prevenção situacional a implementar aquando dos deslocamentos dos Grupos Organizados de
Adeptos, das comitivas, na circulação e acessos ao recinto desportivo e por último objetivo quis- se tomar conhecimento da influência do modelo enquanto atividade de Intelligence na recolha de informações acerca dos Grupos Organizados de Adeptos.
Recorreu- se à metodologia qualitativa de análise de conteúdos devido ao elevado
número de notícias, vídeos, bem como documentos e relatórios dos diversos meios que estiveram presentes, e a análise de entrevistas.
Verificou- se que a GNR tem experiência na organização deste tipo de espetáculos
de risco elevado. No entanto, pela análise das respostas dos entrevistados constatou- se que houve situações que correram menos bem, pois existiram diversos incidentes com alguns feridos ligeiros e houve necessidade de restabelecer a ordem pública. Concluindo - se que se tivesse sido planeado mais meios dissuasores para acompanhar os autocarros dos Grupos Organizados de Adeptos do Futebol Clube do Porto desde o final da autoestrada n.º 2 até
ao complexo desportivo e se tivesse existido acompanhamento dos mesmos até ao local planeado para estacionamento, muito provavelmente os incidentes teriam sido atenuados.
Não dirimidos na sua totalidade porque é quase impossível impedir conflitos quando a motivação de um elevado número de indivíduos está vocacionado para a violência.Abstract Football is a sport phenomenon that moves thousands of people, as was the case in the League Cup Final 2009/2010, therefore it was proposed to assess what was the impact of the policing model implemented by GNR on the citizens in this football sport event. This investigation was integrated in a case study to know the applied means by GNR and all the procedures performed in policing and security in football sports events. Especially, take knowledge of what model was adopted, what was the model influence as a situational prevention measure to implement when the Organized Groups of Fans are moving, the same to teams, in circulation and access to stadium and the last objective was taking knowledge of model influence while Intelligence activity in collecting information’s about Organized Gro ups of Fans. It was resorted to qualitative methodology of contents analysis due to the large number of news, videos, as well as documents and reports from several means that were there, and the analysis of interviews. It was verified that GNR has experience in organizing this type of high risk events. However, in the analysis of interviewees’ answers it was found that there were situations that went less well, because there were several incidents and some people took slight injuries and it was necessary to restore public order. As conclusion, if it had been planned more deterrent means to escort the buses of Organized Groups of Fans from Football Club of Porto since the end of highway n.º 2 until the sports complex and if it had been provided them accompa ny until the place planned for parking, most of the incidents probably would have been mitigated. Not entirely solved because it is almost impossible to prevent conflicts when the motivation of large number of people are directed for violence.

O lobo-guará é uma espécie de ampla distribuição na América do Sul, tendo no Brasil sua maior área de ocorrência. No entanto, as modificações das áreas naturais principalmente destinadas à agropecuária tornam a espécie vulnerável à extinção. A investigação objetivou conhecer em larga escala a área de distribuição potencial gerada por atributos ambientais favoráveis e áreas adequadas à sua ocorrência nos biomas brasileiros e investigar como a espécie responde à estrutura da paisagem, avaliando os efeitos de ambientes modificados pelo homem na sua ecologia espacial, nos padrões de atividade e na movimentação. Modelos de distribuição de espécie foram gerados pelo Maxent, utilizando uma base de pontos de localização de presença a partir de 2000 para o Cerrado (Ce), Pantanal (Pa), Mata Atlântica (MA) e Pampas (Pp) e um conjunto de onze variáveis ambientais não correlacionadas (topográficas, climáticas e paisagísticas). Para análises de ecologia espacial, das atividades e de movimentação, utilizou-se localizações de telemetria (GPS) de animais habitantes de áreas protegidas (AP), e indivíduos em paisagens modificados (AM). Análises de áreas de vida (AV) foram realizadas utilizando o estimador AKDE e associadas com classificação da paisagem local. Os modelos de distribuição do lobo-guará apresentaram uma área de distribuição potencial de 78% do total dos biomas. Apesar de possuírem grandes proporções de áreas adequadas (Ce, 90%; Pa, 93%; MA, 65% e Pp, 6%), somente um pequeno percentual (4,4% do Ce e 4,7% da MA) possui adequabilidade ambiental acima de 50%. Dos atributos que favorecem sua presença, a altitude (para todos os biomas), a precipitação (Ce e Pa), diferenças de temperatura e uso e cobertura do solo (Ma e Pp) foram os mais importantes. Em nível local, animais apresentaram média de AV de 90Km2 em AP e 41Km2 em AM, uma diferença significativa (p<0,01) com áreas diretamente proporcionais ao percentual de áreas naturais na paisagem. Ainda, apesar dos padrões regulares de atividade não mostrarem grandes mudanças, o período de repouso foi significativamente maior (p<0,01) entre os animais AM (46% do dia) que em animais AP (25% do dia). Lobos-guarás de AP e AM não apresentaram grandes diferenças no deslocamento diário com média geral de 14km caminhados por dia, com comprimentos de passos de 1Km. Diferenças no comprimento de passo foram relacionadas à composição da diversidade de contato de classes da paisagem com a proporção de ambientes naturais no passo (quanto maior as variáveis, maior o passo). Passos menores refletem menor persistência de movimento interferindo no deslocamento diário. Com os resultados desse estudo identificou-se a MA e Pa muito importantes, mas o Ce como bioma mais adequado à espécie. Foram encontrados indícios de que a estrutura de suas AV, o uso da paisagem, as atividades e movimentação são afetados pela paisagem modificada. Isso pode comprometer a viabilidade populacional, interferindo na presença em uma área e refletindo no seu potencial de distribuição. As estratégias de manejo de uso do solo, e a recuperação e conexão de áreas adequadas são urgentes e necessárias para que o lobo-guará permaneça presente e funcional nas paisagens dos biomas brasileiros.The maned wolf has an extensive distribution range throughout South America with Brazil holding the largest portion of this area. However, the species is presently under a vulnerable status due to natural habitats alteration especially from farming and ranching. This study aimed to observe in large scale the potential distribution area indicated by favorable environmental attributes and suitable habitats to its presence within the Brazilian biomes and further to investigate how the species respond to the landscape structure, evaluating the effects of human-modified landscapes on its spatial ecology, activity patterns and movements. Species distribution models were generated using Maxent with a database of presence-only locations from 2000 though 2015, of the Cerrado (Ce), Pantanal (Pa), the Atlantic Forest (AF), and the Pampas (Pp) biomes, and eleven uncorrelated environmental variables (topographic, climatic, and landscape-based). As for the spatial ecology, activity and movement analysis, GPS-based telemetry locations were used from animals inhabiting protected (PAs) and disturbed areas (DAs). Home range (HR) analysis was performed using the AKDE estimator and then associated with the landscape-classified image. The distribution models for the maned wolf showed a potential distribution area of 78% of the total biomes range. Despite the high proportion of suitable areas (Ce, 90%; Pa, 93%; AF, 65%, and Pp, 6%), only a small percentage of the biomes (4.4% for Ce and 4.7% for AF) presented values over 50% suitable. Concerning the attributes that favor its presence, the altitude (for all the biomes), the precipitation (Ce and Pa), the temperature differences and land use (AF and Pp) were the most important. At the local scale, maned wolves showed HR sizes (average) with significant differences (p<0.01) between the 90Km2 (PA) and 41Km2 (DA) with HR size directly related to the proportion of natural areas. Although the general activity patterns were not considerably different between PA and DA, the resting periods of DA\'s animals (46% of the day) were significantly different (p<0.01) than the period of PA\'s wolves (46% of the day). Animals did not show changes on the daily movement patterns, accounting with 14km in general average and 1km of average step length (no major differences as well). The variation on the step length was related to the association of the diversity of contacts between landscape classes with the proportion of natural classes at each step (as bigger the variable values, bigger the step). As a consequence of smaller steps, constancy of movement decreases. Considering the results, the AF and Pa outstand as very important biomes, however the Ce was indicated as the most suitable biome. Furthermore, the research indicated signs that the HR structure and the landscape use, besides the activity patterns and the movement are affected by altered landscapes. This might compromise the population viability, interfering directly on its presence in an area and affecting the species distribution. Thus, a proper land use management aiming the recovering of degraded habitats is an important strategy tor the maned wolf conservation, so the species can long last survive across the Brazilian biomes.

Mestrado em Engenharia Eletrónica e TelecomunicaçõesIn recent years, Internet has been assuming a fundamental role in everyday life. Traffic demands are increasing in such a way that the available technologies will presumably no longer satisfy the raised requirements. For the last years, operators have expressed a clear interest in the implementation and development of Passive Optical Network (PON) to provide several services and applications to a high flow rate per client. Comparing to other access technologies, PON is very attractive mainly due to reduction of maintenance and to the operational cost efficiency. As a consequence, PON systems were standardized and developed in the whole world, but the everincreasing bandwidth demand makes this type of network need to evolve. Therefore, the current standardized technologies Gigacapable PON and XG-PON need to be upgraded to Next-Generation PON2. In order to protect the initial investment and to reduce the operational costs, operators should keep the current optical distribution network, providing the technologies coexistence in the same fiber. The principle of NG-PON2 is to improve previous technologies, in terms of capacity, ODN compatibility, bandwidth and cost-efficiency. In April 2012, Full Service Access Network (FSAN) selected the time and wavelength multiplexing PON (TWDM-PON) technology as the solution of choice for NG-PON2. Almost one year later, ITU-T G.989.1 came out, providing some wavelength plans proposals. The ability to operate on existing fiber ODN, coexisting with legacy PON is the most important requirement. The current dissertation is based on the study of TWDM-PON upstream transmission. Both GPON and XG-PON work in burst mode for upstream direction, therefore in the current study also that type of data transmission is considered for upstream TWDM-PON. Once using this transmission mode, some parameters have to be taken into consideration, as the packets size and their separation length in order to understand which frame fits the best, considering the system performance. In the actual study, it was supposed to visualize transients in each packet, however it was experimentally proved that once the lifetime of the carriers is less than the burst time, it was not possible to identify any of them. It was also verified that increasing the guard time will decrease the performance of the system.
A Internet tem vindo a assumir um papel fundamental no quotidiano de cada utilizador. A largura de banda exigida é cada vez mais alta, desta forma, as tecnologias actualmente disponíveis acabarão por deixar de satisfazer os requisitos emergentes. Nos últimos anos, as operadoras têm manifestado um interesse evidente no desenvolvimento de Redes Ópticas Passivas (PON), com o intuito de fornecer vários serviços e aplicações a uma taxa de fluxo elevada por cliente. Comparando com outras tecnologias de acesso, as redes PON são muito actrativas devido à sua baixa manutenção e aos custos/eficiência de operação. Como consequência, os sistemas PON foram padronizados e desenvolvidos em todo o mundo. No entanto, este tipo de tecnologia necessita de progredir ao longo do tempo, mantendo a satisfação dos requisitos de tráfego que lhe serão impostos. Assim, as tecnologias actualmente implementadas: GPON e XG-PON, necessitam de sofrer um upgrade para NG-PON2 (Next- Generation PON 2). De modo a proteger o investimento inicial, reduzindo os custos de operação, as operadoras devem manter e reutilizer a ODN já implementada, possibilitando a coexistência das tecnologias na mesma fibra. NG-PON2 é uma melhoria da capacidade, da compatibilidade na ODN, largura de banda e custo-eficiência das tecnologias anteriores. Em Abril de 2012, a FSAN selecionou a tecnologia TWDM-PON (Time and Wavelength Division Multiplexing PON) como solução do projecto NG-PON2. Um ano após a sua seleção, a norma ITU-T G.989.1 foi publicada, propondo alguns planos de comprimentos de onda. A coexistência de TWDM-PON com as PON anteriores na mesma ODN é o requisite mais importante. A presente dissertação baseia-se no estudo de transmissão upstream de TWDM-PON. Ambos GPON e XG-PON operam em modo burst para a direção upstream. Uma vez utilizao este modo de transmissão, é necessário considerer determinados parâmetros como o tempo de separação interburst – guard time, tal como o comprimento de cada pacote, com o intuito de compreender o impacto da variação destes mesmos campos no desempenho do sistema. No presente estudo, era susposto visualizar transientes em cada pacote de transmissão, no entanto foi comprovado experimentalmente, que uma vez que o tempo de vida dos portadores do EDFA selecionado é menor que o intervalo de cada burst, não se identificaram transientes. Verificou-se também que, o aumento da separação interburst degrada o desempenho do sistema.

This work is born from the researcher's experience within the prison system as a professor of criminology 1997-1999 in various prisons in the state of São Paulo, teaching for prison guards, commonly called jailers. From his observation sharp difference among their students and others, given that the training provided by the Penitentiary Academy at the time was planned for the prison model was modified with a new mindset for these professionals. For various reasons, the group of teachers was extinguished and the training course for prison guards was destroyed, and thus the formation of the new agent became ill, hurting himself and the social group they belong to. Faced with so many problems arising from the expansion of prisons in Sao Paulo, and the huge increase of prisoners within the São Paulo prisons, it had to rescue the technical course on prison security officer training from 1997 to 1999 and from this experience design, the final conclusions some targets in the emergence of new business resulting from this experience, as well as the formation of criminologists and some goals to be met in prison
O presente trabalho nasce da experiência do pesquisador dentro do sistema penitenciário como professor de criminologia de 1997 a 1.999, em diversos presídios no Estado de São Paulo, dando aulas para agentes de segurança penitenciária, vulgarmente chamado de carcereiros. De sua observação nota nítida diferença entre seus alunos e os demais, tendo em vista que a formação fornecida pela Academia Penitenciária na época foi planejada para que o modelo de prisão fosse modificado com uma nova mentalidade para estes profissionais. Por diversos motivos, o grupo de professores foi extinto e o curso de formação de agentes de segurança penitenciária foi destruído, e assim a formação do novo agente se tornou precária, prejudicando a ele próprio e ao segmento social que pertencem. Diante de tantos problemas decorrentes da expansão de presídios em SP, e o aumento enorme de presos dentro das prisões paulistas, foi preciso resgatar o curso técnico de formação de agente de segurança penitenciária de 1997 a 1999 e a partir desta experiência projetar, nas conclusões finais, algumas metas dentro do surgimento de novos profissionais decorrentes desta experiência, bem como a formação de criminólogos e algumas metas a serem cumpridas na prisão

Digital Video Broadcasting (standard DVB) is a system for transmission of the television signals in the digital form. There are used a various types of modulations in this system as QPSK modulation is used in the systems of satellite video broadcasting DVB-S (Satellite) and M-QAM modulations in the cable transmitting DVB-C (Cable). This paper mainly deals with system of the terrestrial digital video broadcasting DVB-T (Terrestrial), where OFDM modulation is used. This type of signal processing is more resistant to the distortions caused by multipath transmitting, which is main problem in the DVB-T. Matlab application, which can simulate digital modulation and demodulation of the transmission signals in the DVB-T, is created in this thesis. The models of the transmission channel is inserted between structures of modulator and demodulator. The user of this application can set the parameters of the broadcasting (e.g. constellation, OFDM mode, guard interval insertion) and the type of distortions (additive noise, reflected and delayed signals). By calculation of the channel bit error rate (BER) user can study influences of broadcasting parameters to the quality of transmission.

Economic development in Taiwan has raised the standard of living in recent years, therefore , demand for better environmental quality has rose, and local parks has become one of the most important recreational space for people . The facilities and safety of local parks has become a major indicator for government’s citizen satisfactory survey. Park guards need to patrol and report on the conditions of park facilities , supervise park sanitary and assure safety to maintain high quality of the parks. So work schedules of the park guards need to be arranged in a practical but also equal fashion. The arrangement of park guard which was not an optimistic arrangement was usually made artificially in the pastime. The front office usually takes much time to deal with in the past as well. The most important issue that front office concerns is to keep the manpower arrangement optimistic and fair. We develop an optimistic manpower assignment’s model to resolve the minimum working days of park guard and the combination of manpower assignment according to the study focusing on the sanitary auditing activities for the Park Management Office by utilizing LINGO 8.0 software. The susceptibility of the parameters act on the minimum working days help us to realize that the minimum working days change by the parameters have been setted in this model. After case studying, we find that the manpower assignment model is superior to artificial method. The results reveal that the optimistic model looks after benefit and fairness of manpower assignment. It can be the manpower assignment’s reference of park management officials in practice.

Indoor horticulture offers a promising solution for sustainable food production and
is becoming increasingly widespread. However, it incurs high energy and cost
due to the use of artificial lighting such as high-pressure sodium lamps,
fluorescent light or increasingly, the light-emitting diodes (LEDs). The energy
efficiency and light quality of currently available lighting is suboptimal, therefore
less than ideal for sustainable and cost-effective large-scale plant production.
Here, we demonstrate the use of high-powered single-wavelength lasers for
indoor horticulture. Lasers are highly energy-efficient and can be remotely guided
to the site of plant growth, thus reducing on-site heat accumulation. Besides,
laser beams can be tailored to match the absorption profiles of different plants.
We have developed a prototype laser growth chamber and demonstrate that
laser-grown plants can complete a full growth cycle from seed to seed with
phenotypes resembling those of plants grown under LEDs. Importantly, the
plants have lower expression of proteins diagnostic for light and radiation stress.
The phenotypical, biochemical and proteomic data show that the singlewavelength
laser light is suitable for plant growth and therefore, potentially able to unlock the advantages of this next generation lighting technology for highly
energy-efficient horticulture. Furthermore, stomatal movement partly determines
the plant productivity and stress management. Abscisic acid (ABA) induces
stomatal closure by promoting net K+-efflux from guard cells through outwardrectifying
K+ (K+ out) channels to regulate plant water homeostasis. Here, we show
that the Arabidopsis thaliana guard cell outward-rectifying K+ (ATGORK) channel
is a direct target for ABA in the regulation of stomatal aperture and hence gas
exchange and transpiration. Addition of (±)-ABA, but not the biologically inactive
(−)-isomer, increases K+ out channel activity in Vicia faba guard cell protoplast. A
similar ABA-modulated K+ channel conductance was observed when ATGORK
was heterologously expressed in human embryonic kidney 293 (HEK-293) cells.
Alignment of ATGORK with known PYR/PYL/RCARs ABA receptors revealed
that ATGORK harbors amino acid residues that are similar to those at the latchlike
region of the ABA-binding sites. In ATGORK, the double mutations K559A
and Y562A at the predicted ABA-interacting site impaired ABA-dependent
channel activation and reduced the affinity for ABA in vitro.

Dissertação de mestrado em Gestão de Recursos HumanosEsta investigação procura aferir se a liderança autêntica e a personalidade de um líder têm implicações significativas nos resultados da liderança. Para tal, foram verificadas as relações entre a liderança autêntica, os cinco fatores da personalidade e os resultados da liderança, nomeadamente: (a) satisfação dos colaboradores com o líder; (b) eficácia percecionada do líder pelos colaboradores; (c) esforço extraordinário dos colaboradores; (d) desempenho do líder avaliado pelos superiores hierárquicos. Foi utilizada uma amostra de conveniência constituída por elementos de uma força de segurança, composta por três grupos: (a) colaboradores (n=476); (b) líderes (n=61); (c) chefia dos líderes (n=104). Os colaboradores pronunciaram-se sobre o estilo de liderança autêntica do seu Comandante tendo utilizado o Authentic Leadershio Inventory (Neider & Schriesheim, 2011), assim como, sobre os resultados da sua liderança. Os líderes fizeram uma autoavaliação sobre a perceção da sua personalidade através do Big Five Inventory (John, Naumann & Soto, 2008), e por fim, os superiores hierárquicos avaliaram o desempenho do líder. Os resultados apontam para uma relação significativa positiva entre o constructo da liderança autêntica com ambas as variáveis dos resultados da liderança. Quanto à relação entre a personalidade e os resultados da liderança percecionados pelos colaboradores, verificou-se que a extroversão e a amabilidade apresentam resultados significativos positivos, e o neuroticismo resultados significativos em sentido negativo, sendo que, nos resultados da liderança percecionados pelos superiores hierárquicos, são apenas significativos a extroversão em sentido positivo e o neuroticismo em sentido negativo. Como tal, releva-se a importância que a liderança autêntica e a personalidade de um líder podem ter nos resultados da ação de liderança, discutindo-se estas implicações para a gestão de recursos humanos no contexto organizacional.
This research seeks to find if authentic Ieadership and personality of a leader have significant implications on the results of his leadership. The relationships between authentic leadership and the five personality factors were verified with the results of the Ieadership: (a) satisfaction of the collaborators with the leader; (b) perceived effectiveness of the leader by the collaborators; (c) extraordinary effort of collaborators; (d) performance of the leader evaluated by the hierarchical superiors. We used a convenience sample from a security force elements, composed by three groups: (a) collaborators (n = 476); (b) leaders (n = 61); (c) hierarchical superiors (n = 104). The collaborators evaluated the authentic Ieadership style of their Commander with the Authentic Leadership Inventory (Neider & Schriesheim, 2011), as well as the results of their Ieadership. Leaders made a self-assessment about their personality through the Big Five Inventory (John, Naumann & Soto, 2008). The hierarchical superiors evaluated the leader's performance. The results point to a significant positive relationship between the construct of authentic leadership with both variables of Ieadership outcomes. In the relationship between the personality and the results of the Ieadership perceived by the collaborators it was verified that extroversion and agreeableness have significant positive results In the other hand the neuroticism have significant results in a negative sense. The results of the leadership perceived by the superiors, only extroversion have significant positive results and neuroticism in the negative sense. Lastly we highlight the importance that authentic leadership and the personality of a leader can have in the results of a leader's command action, discussing these implications for the management of human resources in the organizational context.

This study investigates the management method of psychological counseling volunteers at Coast Guard Administration, Executive Yuan through in-depth interviews, detailed surveys and other means. Major findings are listed below: 1. Recruitment: Volunteer applications mainly come from three main groups of people. They are current and former employees at CGA, psychological counseling professionals, and retired civilians. 2. Training: After passing selection and interview processes, psychological counseling volunteers are required to take basic and specialized training classes. Upon passing final examinations, volunteers will receive professional certificates, volunteer ID, and service record book. 3. Appointment: Having completed the required classes, volunteers will be stationed at different posts according to the plans instituted by CGA. Volunteers displaying inappropriate behaviors such as violation of law and disobeying supervisors, subject to be reviewed by post authority, can be reported to CGA. 4. Assessment: Local authority will regularly send investigators to posts to gauge the performance of volunteer as an individual and as a team member. Guidance to volunteers'' career path will also be provided. 5. Evaluation: Reviews on volunteers are based on total hours devoted. Awards will be given to those whose total hours meet the required threshold. In addition, those with extraordinary records will be reviewed by task committee for public recognition.

Full textAbstract:
Summaries in English, Afrikaans and ZuluOrientation: Security personnel work in a high risk and consequently high stress environment. This may negatively affect their wellbeing. Owing to the high crime rate in South Africa, one of the continuous stressors security personnel experience might be fearing for their lives. If security personnel fail to use effective coping strategies they will remain stressed, and this may have a negative impact on them, and their organisation or community. Challenges such as work stress in the South African security industry have not been comprehensively researched or documented (Sibanyoni, 2014). Consequently, no South African questionnaire measuring coping with stress or a stress management model for dealing with stress in a security environment, could be found. Research purpose: The general aim of the research was to develop a valid and reliable coping questionnaire and stress management model for high stress security occupations. Research methodology: A questionnaire development process, as suggested by scientific literature, was followed. The process entailed (1) determining coping strategies by means of a literature review, (2) developing the coping questionnaire, (3) administering the questionnaire to the target population, and (4) statistical analysis. The stress management model was developed by combining the results of the confirmatory factor analysis (CFA) and canonical correlation analysis (CCA). The development of the questionnaire was based on a sample of 381 active duty security personnel working in a high stress security environment in South Africa. Main findings: The study resulted in the development of a psychometrically sound 39-item questionnaire. The following 12 empirically validated healthy and unhealthy coping strategies were identified: (1) social support, (2) group cohesion, (3) physical exercise, (4) relaxation, (5) social media addiction, (6) healthy sleeping habits, (7) healthy diet, (8) training, (9) humour, (10) religion, (11) avoidance, and (12) denial. CFA confirmed both the construct and content validity, and composite reliability. The questionnaire was found to be invariant, and could thus be applied to different groups in high stress security occupations. A stress management model indicating the interrelationship between personality and coping was also developed. Contribution/value-add: The main contribution of this study was the development of a valid coping questionnaire and stress management model. By identifying the specific coping strategies, targeted stress management interventions could be developed. This could contribute to the overall wellness of security personnel working in high stress occupations, resulting in a healthy organisation and sound relationships with the community. Security organisations could also use the model during assessments to identify candidates with personality traits that would lead to healthier coping strategies, thereby selecting personnel that could better adapt to a security environment.
Oriëntasie: Sekuriteitspersoneel werk in ’n hoë risiko en gevolglik ’n stresvolle omgewing. Dit kan hulle welstand negatief beïnvloed. As gevolg van die hoë misdaadsyfer in Suid-Afrika kan een van die deurlopende stressors wat sekuriteitspersoneel ervaar ’n vrees vir hulle lewens wees. Indien sekuriteitspersoneel nie effektiewe streshantering strategieë gebruik nie, kan hulle voortdurend stres ervaar en dit kan ’n negatiewe impak op hulleself, hulle organisasie of gemeenskap hê. Uitdagings soos beroepstres in die Suid-Afrikaanse sekuriteitsindustrie is nog nie deeglik nagevors of gedokumenteer nie (Sibanyoni, 2014). Gevolglik kon daar vir die sekuriteitsomgewing geen Suid-Afrikaanse vraelys wat streshantering meet of ’n stresbestuursmodel gevind word nie. Doel van die navorsing: Die algemene doel van die navorsing was om vir stresvolle sekuriteitsberoepe ’n geldige en betroubare streshanteringsvraelys en stresbestuursmodel te ontwikkel. Navorsingsmetodologie: ’n Vraelys ontwikkelingsproses, soos deur wetenskaplike literatuur voorgestel, is gevolg. Die proses het die volgende behels: (1) die vasstel van die streshantering strategieë deur middel van ’n literatuuroorsig, (2) die ontwikkeling van die streshanteringsvraelys, (3) administrasie van die vraelys aan die teiken populasie en (4) statistiese analise. Die stresbestuursmodel is ontwikkel deur die resultate van die bevestigende faktoranalise (BFA) en die kanoniese korrelasie analise te kombineer. Die ontwikkeling van die vraelys is gebaseer op ’n steekproef van 381 aktiewe diens sekuriteitspersoneel wat in Suid-Afrika in ’n stresvolle sekuriteitsomgewing werk. Hoofbevindinge: Die studie het tot ’n psigometries betroubare 39-item vraelys gelei. Twaalf empiries gestaafde gesonde en ongesonde streshantering strategieë is geïdentifiseer naamlik: (1) sosiale ondersteuning, (2) groep kohesie, (3) fisiese oefening, (4) ontspanning, (5) sosiale media verslawing, (6) gesonde slaapgewoontes, (7) gesonde dieet, (8) opleiding, (9) humor, (10) godsdiens, (11) vermyding en (12) ontkenning. BFA het die konstruk- en inhoudsgeldigheid so wel as die saamgestelde betroubaarheid bevestig. Die vraelys is invariant en kan dus op verskillende groepe in hoë stres sekuriteitsberoepe toegepas word. ’n Stresbestuursmodel wat die verwantskap tussen persoonlikheid en streshantering aandui is ook ontwikkel. Bydrae/waardetoevoeging: Die belangrikste bydrae van hierdie studie was die ontwikkeling van ’n geldige streshanteringsvraelys en stresbestuursmodel. Deur die spesifieke streshantering strategieë te identifiseer kan gefokusde streshantering intervensies ontwikkel word. Dit kan tot die algehele welstand van sekuriteitspersoneel wat in stresvolle beroepe werk bydra en derhalwe ’n gesonde organisasie en goeie verhoudings met die gemeenskap. Sekuriteitsorganisasies kan ook tydens keurings die model gebruik om kandidate met persoonlikheidstrekke, wat tot gesonder streshantering strategieë sal lei, te identifiseer en dus personeel kies wat beter by ’n sekuriteitsomgewing sal aanpas.

A GNR é uma força de segurança única em Portugal, de natureza militar, constituída essencialmente por militares organizados num corpo especial de tropas, dotada de autonomia administrativa e integrada no Ministério da Administração Interna. A lei da sua orgânica, promulgada em 2007 e concretizada em 2009, tem por objecto o exercício de funções de soberania na qual a vertente de força de segurança assenta em muito na capilaridade dos postos territoriais que desenvolvem a sua missão fundamentalmente na área policial assegurando a legalidade democrática e garantindo a segurança interna e os direitos dos cidadãos.
Definiu-se como objecto da dissertação o actual dispositivo dos postos territoriais da Guarda, no território continental português, visando caracterizá-lo relativamente à sua envolvente externa tendo, para o efeito, sido seleccionados os indicadores da população, da área, da relação administrativa e judicial, da localização específica e das distâncias mais próximas entre eles.
Ao longo do trabalho foi utilizado o método indutivo com recurso a diversas técnicas (pesquisa bibliográfica, análise documental, estatística e observação participativa) e, em especial, a um inquérito que permitiu arrolar informação sobre 92,69 % dos postos da Guarda num universo de quatrocentos e sessenta e cinco.
O modelo secular do dispositivo dos postos territoriais é uma competência distintiva da GNR que se caracteriza por ser uma malha sistemática de ocupação do território, composta por unidades elementares polivalentes, intermitentes, multiformes e muito desiguais. Independentemente da existência de um posto da Guarda constituir um símbolo da soberania nacional interessa que não seja apenas isso pois trata-se de um escalão fundamentalmente operacional com profundas responsabilidades pelo cumprimento da missão policial da GNR.
Em jeito prospectivo consideramos que os postos territoriais devem ostentar uma autonomia operacional necessária e, sem excepção, dispor de uma envolvente externa coerente e provida da adequada envergadura, legitimando materialmente a sua existência, fomentando-se o equilíbrio relativo da mais pequena unidade orgânica da Guarda, sem prejuízo da proximidade às populações, do conhecimento actual e permanente do espaço social, de se assegurarem tempos de intervenção aceitáveis e da salvaguarda de constrangimentos geográficos, sociais e económicos.

V Curso de estudos avançados em Direito e Segurança 2008/2010A GNR é uma força de segurança única em Portugal, de natureza militar, constituída essencialmente por militares organizados num corpo especial de tropas, dotada de autonomia administrativa e integrada no Ministério da Administração Interna. A lei da sua orgânica, promulgada em 2007 e concretizada em 2009, tem por objecto o exercício de funções de soberania na qual a vertente de força de segurança assenta em muito na capilaridade dos postos territoriais que desenvolvem a sua missão fundamentalmente na área policial assegurando a legalidade democrática e garantindo a segurança interna e os direitos dos cidadãos. Definiu-se como objecto da dissertação o actual dispositivo dos postos territoriais da Guarda, no território continental português, visando caracterizá-lo relativamente à sua envolvente externa tendo, para o efeito, sido seleccionados os indicadores da população, da área, da relação administrativa e judicial, da localização específica e das distâncias mais próximas entre eles. Ao longo do trabalho foi utilizado o método indutivo com recurso a diversas técnicas (pesquisa bibliográfica, análise documental, estatística e observação participativa) e, em especial, a um inquérito que permitiu arrolar informação sobre 92,69 % dos postos da Guarda num universo de quatrocentos e sessenta e cinco. O modelo secular do dispositivo dos postos territoriais é uma competência distintiva da GNR que se caracteriza por ser uma malha sistemática de ocupação do território, composta por unidades elementares polivalentes, intermitentes, multiformes e muito desiguais. Independentemente da existência de um posto da Guarda constituir um símbolo da soberania nacional interessa que não seja apenas isso pois trata-se de um escalão fundamentalmente operacional com profundas responsabilidades pelo cumprimento da missão policial da GNR. Em jeito prospectivo consideramos que os postos territoriais devem ostentar uma autonomia operacional necessária e, sem excepção, dispor de uma envolvente externa coerente e provida da adequada envergadura, legitimando materialmente a sua existência, fomentando-se o equilíbrio relativo da mais pequena unidade orgânica da Guarda, sem prejuízo da proximidade às populações, do conhecimento actual e permanente do espaço social, de se assegurarem tempos de intervenção aceitáveis e da salvaguarda de constrangimentos geográficos, sociais e económicos.

This thesis is dedicated to study of interactions of utra-high energy cosmic rays using measured data from the Pierre Auger Observatory, automatic alarm system called Shift Guard and analysis of correlation of temperature and detector response. The Pierre Auger Observatory is the largest experiment to study ultra-high energy cosmic rays. The assumed relation between temperature and fluorescence detector response is studied together with descriptive temperature analysis, which shows that the air-conditioning system is not able to stabilize temperature enough. The temperature influence on camera response is investigated in order to measure the calibration correction factor. Shift Guard - the alarm system dedicated to protect fluorescence detectors and data taking is introduced and its functionality is described. The alarm system informs shifters about some events and situations that can endanger detector or deteriorate data quality. The basic parameters and alarm system logic are described together with light and sound signals. The discrepancy between measured and predicted number of muons at ground level calculated by EAS generators is showed and possible sources of this disagree- ment are studied. The result of massive dark photons decay in EAS as one of exotic muon source is presented. The analysis...

O presente Trabalho de Investigação Aplicada encontra-se subordinado ao tema “O Modelo Global do Uso da Força na Guarda Nacional Republicana” e tem como principal objetivo caracterizar o emprego do Modelo Global do Uso da Força na Guarda Nacional Republicana, procurando determinar as potencialidades e vulnerabilidades do seu processo de implementação, o seu nível de adequabilidade, as necessidades de ajustamentos e as possíveis alterações à implementação, em ordem a desenvolver e potencializar o respetivo emprego na Guarda Nacional Republicana.
Para se atingir os objetivos da investigação, optou-se por se seguir uma abordagem qualitativa, utilizando-se a análise documental e a aplicação de entrevistas exploratórias e confirmatórias, como técnicas de recolha de dados. As entrevistas foram dirigidas a peritos no âmbito do Modelo Global do Uso da Força e a militares das categorias de Oficiais, Sargentos e Guardas, do Grupo de Intervenção de Operações Especiais, do Grupo de Intervenção de Ordem Pública, do Destacamento de Intervenção de Lisboa e do Destacamento Territorial de Sintra.
A investigação encontra-se dividida em duas fases essenciais. Inicialmente procedeu-se à revisão da literatura, abordando-se os conceitos e as problemáticas subjacentes ao uso da força policial. Ainda nesta fase, realizou-se uma análise do Modelo Global do Uso da Força da Guarda Nacional Republicana, evidenciando o seu contexto de aplicação e as suas características. Numa segunda fase, procedeu-se ao trabalho de campo, com o intuito de recolher os dados necessários à componente prática da investigação.
Como principais conclusões da presente investigação, ressaltam os aspetos positivos da implementação e a aplicação do Modelo Global do Uso da Força na Guarda Nacional Republicana, verificando-se que o mesmo não só orienta corretamente a atuação dos militares da Guarda, como representa uma ferramenta de auxílio ao processo de tomada de decisão. A fim de colmatar as vulnerabilidades do processo de implementação e potencializar a utilização do referido modelo, deve ser realizada uma aposta no treino e na formação, bem como um investimento ao nível da distribuição de equipamento e armamento.

O Trabalho de Investigação Aplicada elaborado intitula-se: “Otimização de rotas na Guarda Nacional Republicana: sua aplicação a Destacamento Territorial”. Neste sentido, pretende-se analisar as situações em que se possa efetivar uma otimização de rotas e, paralelamente, construir rotas eficientes, estudando a aplicabilidade de ferramentas que auxiliam as tomadas de decisão.
Esta investigação assenta no método hipotético-dedutivo e fundamenta-se nas fases de estudo em Investigação Operacional referidas por Taha (2008) e Hillier e Lieberman (2013), tendo em vista a verificação de hipóteses, a resposta a perguntas derivadas e concluindo com a resposta à pergunta de partida.
Neste trabalho são abordados os temas de otimização de rotas e patrulhamento de um ponto de vista teórico, apresentando-se, de seguida, a metodologia e procedimentos utilizados e, ainda, a apresentação, análise e discussão de resultados. Por fim, são expostas as conclusões inferidas, tecendo-se recomendações para investigações futuras.
Finalizada a investigação, observou-se que o modelo de otimização construído revela grandes vantagens na redução de quilómetros percorridos e de tempo despendido para planeamento, através de ferramentas que representam restrições reais, sendo as suas interfaces bastante intuitivas. Assim sendo, este permite a otimização de um processo comummente extensível a todo o dispositivo territorial, minimizando custos e não inviabilizando um policiamento de proximidade, o alcance a toda a população e o aumento do sentimento de segurança. Deste modo, conclui-se que o modelo contribui de forma significativa para a obtenção de benefícios operacionais e ganhos de eficiência.
No fundo, este trabalho também pretende mostrar o quão importante é a Investigação Operacional na otimização de procedimentos, na melhoria das tomadas de decisão e na oportunidade de tornar o trabalho da Guarda Nacional Republicana mais económico, eficiente e eficaz.The research applied prepared is entitled: “Route Optimization in National Republican Guard: its application to Territorial Detachment.” In this sense, it is intended to analyze the situations in which a route optimization can be applied and, in parallel, to construct efficient routes by studying the tools applicability that aid to decision making. This research is based on the hypothetical-deductive method and is based on the study phases in operational research referred by Taha (2008) and Hillier & Lieberman (2013), to test hypotheses, answer to the derived questions and conclude with the answer to the initial question. In this work, the topics of route optimization and patrolling are approached from a theoretical point of view, presenting then the methodology and procedures used and the presentation, analysis and discussion of results. Finally inferred conclusions are presented and recommendations are expressed for future investigations. Completed the investigation, it was observed that the optimization model built shows great advantages in reducing kilometers traveled and time spent for planning, using tools that represent real constraints with very intuitive interfaces. Therefore, this allows the optimization of a process commonly extended to all territorial device, minimizing costs and allowing a proximity patrolling that involves the entire population and increases sense of security. In this way, it is concluded that the model contributes significantly to the achievement of operational benefits and efficiency gains. This paper also aims to show how important it is operational research on optimization of procedures, improving decision making and the opportunity to make Republican National Guard work more economic, efficient and effective.

Tese de doutoramento, Geologia (Hidrogeologia), Universidade de Lisboa, Faculdade de Ciências, 2010.O presente trabalho desenvolve-se na mina do Castelejo, uma antiga exploração de urânio hoje desactivada, situada no planalto beirão, próximo de Gouveia, na base da Serra da Estrela. A área é actualmente objecto de recuperação ambiental por parte da empresa encarregue de gerir os passivos ambientais decorrentes da exploração mineira em Portugal. A exploração decorreu entre 1979 e 1990 em duas cortas a céu aberto, tendo sido extraídas cerca de 1.000.000 toneladas de rocha, que produziram cerca de 132 toneladas de minério (U3O8). Mais tarde, em 1992, uma das cortas foi utilizada para lixiviação ácida de minério pobre, proveniente tanto desta mina, como de outras situadas nas proximidades, o que permitiu produzir ainda cerca de 22,5 toneladas de U3O8. Os dados das análises de águas, resultantes da monitorização química a furos e poços localizados no perímetro da área mineira, foram tratados através de análise multivariada, tendo resultado na caracterização hidrogeológica preliminar da área mineira. Foram efectuadas duas campanhas de prospecção geofísica, com vista à caracterização da fracturação, no sentido de proceder à determinação de vias de escoamento preferencial da água. Os resultados obtidos foram cruzados e complementados com análise de lineamentos e informação retirada da bibliografia. Os objectivos prosseguidos com a realização do trabalho visam a caracterização hidrogeoquímica e hidrogeológica da envolvente da área mineira, efectuada por aplicação de um modelo de especiação do urânio e da modelação do escoamento e transporte, com base na informação recolhida. O trabalho tem ainda em vista avaliar a possível contaminação da água subterrânea relacionada com as actividades mineiras, bem como a sua eventual dispersão.
The present work takes place on Castelejo mine, an old uranium exploration currently inactive, located near Gouveia, on Beirão plateau at Serra da Estrela base level. The area is currently undergoing environmental remediation by the company in charge of managing the environmental liabilities arising from mining in Portugal. Exploitation took place between 1979 and 1990 in two open pits, having been drawn about 1,000,000 tons of rock, which produced around 132 tonnes of ore (U3O8). Later, in 1992, one open pit was used for acid leaching of low-grade ore, both from this mine as from others located nearby, allowing further production of about 22.5 tonnes of U3O8. The data analysis of water, from monitoring chemical holes and wells located within the boundaries of the mining area, were treated by multivariate analysis, resulting in the preliminary hydrogeologic characterization of the mining area. There two geophysical campaigns for the characterization of fracturing have been made, in order to identify preferential paths of water flow. Obtained results were cross-checked and supplemented with lineament analysis and other data taken from literature. The objectives pursued with the completion of work aimed at the characterization of the hydrogeochemical and hydrogeological environment of the mining area, by means of an uranium speciation model and the modeling of flow and transport, based on information collected. The work also aims to assess the possible groundwater contamination related to mining, and its eventual dispersal.

Este Trabalho de Investigação Aplicada encontra-se subordinado ao tema “Do modelo de policiamento Tradicional ao modelo Intelligence-Led Policing: Estudo Comparativo”. A presente investigação estuda dois modelos de policiamento de forma sistemática e isolada, permitindo a realização de uma comparação entre ambos. Contudo, não se limita à mera comparação de modelos, apresenta como objetivo geral a análise do emprego de um policiamento orientado pelas informações na Guarda Nacional Republicana, com o intuito de perceber se este se apresenta benéfico, bem como, a pergunta de partida desta investigação é remetida para a aplicabilidade do modelo referido. No que concerne à metodologia empregue, esta segue o método dedutivo, tendo a investigação o intento de dar resposta a quatro perguntas derivadas e à pergunta de partida da investigação. O quadro teórico e concetual que sustenta o presente estudo, resulta da pesquisa bibliográfica e análise de documentos institucionais. Por fim, a investigação empírica apoia-se na realização de entrevistas, seguindo assim este estudo, uma abordagem qualitativa. Finda a investigação, conclui-se que têm vindo a ser empregues na Guarda Nacional Republicana metodologias referentes ao modelo Intelligence-Led Policing. Todavia esta tipologia de trabalho encontra-se em desenvolvimento, não sendo ainda aferido este modelo de forma estruturada, assumido oficialmente pela Instituição. Nesta senda, é delineado o investimento tecnológico, nomeadamente em tecnologias de vigilância e na interoperabilidade dos Sistemas de Informações, além de uma formação abrangente às diversas classes sobre a temática, uma estrutura de informações presente em todos os níveis funcionais da Guarda Nacional Republicana e o comprometimento institucional para com o modelo, como requisitos necessários à implementação do mesmo por parte de toda a estrutura da Guarda.

Full textAbstract:
As redes sociais são a força motriz da mudança do paradigma social que vivemos
diariamente. Constituem-se como a principal via de comunicação e partilha de informação,
o que tem levado a um aumento gradualmente acentuado da sua utilização. Através de uma
análise cuidada da informação disponibilizada, é possível ter uma perceção daquilo que é a
realidade social num contexto especifico, pelo que, urge monitorizar as redes sociais no
âmbito policial.
A presente investigação, subordinada ao tema “Contributo para um Modelo de
Monitorização das Redes Sociais pela Guarda Nacional Republicana”, tem como objetivo
geral compreender quais as características, capacidade e âmbito de atuação do modelo de
monitorização policial das redes sociais por parte da Guarda Nacional Republicana. Para
uma melhor orientação da investigação, foram definidos objetivos específicos,
nomeadamente, caracterizar a monitorização nas redes sociais no âmbito da atividade
policial, identificar o espetro de atuação da Guarda Nacional Republicana na
monitorização das redes sociais, identificar as capacidades a desenvolver e as limitações a
mitigar por parte da Guarda Nacional Republicana na monitorização das redes sociais e
caracterizar a atuação da Guardia Civil na monitorização das redes sociais.
A metodologia empregue segue uma matriz dedutiva, com especial enfoque na
análise da atuação da Guarda Nacional Republicana e Guardia Civil no âmbito da
monitorização das redes sociais, visando, através de uma abordagem qualitativa, com
recurso à analise bibliográfica e entrevistas, desenvolver uma cadeia de raciocínio em
ordem descendente, de análise do geral para o particular, com vista a chegar a uma
conclusão.
Concluímos que a informação obtida através da monitorização policial das redes
sociais, quando associada a um determinado contexto social e/ou local e analisada por
especialistas que entendem a realidade social, pode constituir-se como uma ferramenta
preponderante na prevenção criminal, manutenção da ordem pública e paz social. No
entanto, a Guarda Nacional Republicana ainda não desenvolveu esta potencialidade, pelo
que o trabalho desenvolvido neste âmbito é diminuto e com fracos resultados operacionais.
Para alterar esta situação é necessário definir os objetivos que se visa prosseguir com esta
atividade, e consequentemente estabelecer uma framework organizacional. Só após esta tarefa estar definida é que é possível capacitar a Guarda Nacional Republicana de meios
técnicos e humanos.Social networks are the driving force behind the change in the social paradigm we experiment on a daily basis. They constitute the prime way for the communication and information sharing, which has led to a gradually increasing of social media use. Through a careful analysis of the information available, it is possible to have a perception of what social reality is in a specific context, so it is urgent to monitor social networks in the police sphere. The present research, under the theme “Contributo para um Modelo de Monitorização das Redes Sociais pela Guarda Nacional Republicana” has as general objective to understand the characteristics, capacity and scope of action of a police monitoring model of social networks by the Guarda Nacional Republicana. For a better orientation of the research, specific objectives have been defined, namely, to characterize monitoring in social networks within the scope of police activity, to identify the role played by the Guarda Nacional Republicana in monitoring social networks, identify the capacities to be developed and the limitations to be mitigated by the Guarda Nacional Republicana in the Monitoring of Social Networks and characterize the Guardia Civil role in monitoring social networks. The methodology used follows a deductive matrix, with special focus on the analysis of the Guarda Nacional Republicana in and Guardia Civil in the scope of social network monitoring, aiming, through a qualitative approach, using bibliographical analysis and interviews, to develop a chain of reasoning in descending order of analysis from the general to the particular, to obtain a conclusion. We conclude that the information obtained through police monitoring of social networks, when associated with a specific social and / or local context and analyzed by specialists who understand the "terrestrial reality”, may constitute, as a preponderant tool in the criminal prevention and maintenance of public order and social peace. However, the Guarda Nacional Republicana is not awake for this potential, reason why, the work developed in this scope is small and with poor operational results. To change this situation, it is necessary to define the objectives to be pursued with this activity, and consequently establish an organizational framework. Only after this task is defined is it possible to equip the Guarda Nacional Republicana with technical and human means.

The objective of this research was to systematically examine the pasting/gelling and rheological properties of starch pearl model system as a function of mixed gum type (hsian-tsao leaf gum / carboxymethylcellulose or hsian-tsao leaf gum / guar gum) and ratio (0/4, 1/3, 2/2, 3/1,4/0). Rapid visco-analysis results indicated that the viscosity of the polysaccharide/starch mixed systems increased with increasing the ratio of CMC or GG in mixed gum. While HG/CMC=0/4, 1/3, 2/2 and HG/GG=0/4, 1/3, the viscosity of the mixed system was higher than that of starch alone system. Such results suggested an increase in the effective concentration of starch, leading to synergistic interactions with the mixed gum. In thermal analysis, except for HG/GG=0/4, the peak temperature (Tp) of the mixed system was higher and the enthalpy was significantly lower than those of starch alone system. This may be attributed to lower ratios of free water available for starch due to immobilization of water molecules by gums, the lower heat transfer and mass transfer of water, which could make starch gelatinization more difficult in the presence of gum. Dynamic rheological properties test indicated that the storage and loss modulus of the mixed systems increased with frequencies, and tan δ was lower than 1, indicated the composite systems could be classified as weak gels rheologically. Storage modulus of the mixed system increased with increasing refrigerated storage. It is possible that for a gelatinized starch paste, the swollen gelatinized starch granules, consisted mainly of amylopectin, are embedded in the continuous matrix, consisted mainly of amylose. Reordering of amylopectin during storage reinforces the interpenetrating amylose gel matrix due to increase in the rigidity of the granules, which results in an increase in storage modulus.

Full textAbstract:
O Policiamento de Proximidade é o modelo de policiamento atual em Portugal, privilegiando uma postura preventiva e dando relevo à pró-atividade das forças policiais. À Guarda Nacional Republicana, enquanto força policial, cabe-lhe zelar pelos direitos, liberdades e garantias dos cidadãos, constitucionalmente protegidos, através dessa atuação preventiva, procurando intensificar pró-ativamente a sua presença no seio da sociedade. Contudo, por vezes é necessário recorrer a uma intervenção de caráter repressivo, a fim de repor a ordem e visando uma prevenção futura, evitando os comportamentos antissociais.
Torna-se assim pertinente estudar de que forma se articulam a atuação preventiva e repressiva da GNR, de modo a perceber se é possível existir um equilíbrio entre elas, ou se, por alguma razão, existem limitações no seu emprego. O Destacamento Territorial de Coimbra constitui o estudo de caso.
Esta investigação para além de descrever a articulação entre ambas as formas de atuação, pretende ainda identificar aquilo que as caracteriza bem como as suas potencialidades e vulnerabilidades.
De forma a recolher a informação pretendida, foram privilegiadas a análise documental, entrevistas ao Comandante de Destacamento Territorial de Coimbra e aos respetivos Comandantes dos Postos Territoriais, bem como questionários aos militares do destacamento responsáveis por exercerem o patrulhamento. Seguidamente procedeu-se à análise de conteúdo dos dados recolhidos.
Das conclusões retiradas, salienta-se que a falta de recursos principalmente humanos, corresponde a um problema do destacamento, que dificulta uma ação de patrulhamento contínuo junto do cidadão e que contribui para o Policiamento de Proximidade. Denota-se também a intensa fiscalização rodoviária que, apesar de ter uma natureza preventiva, é interpretada pela população com uma imagem de repressão.The Proximity Policing is the current policing model in Portugal, favoring a preventive approach and the emphasis on proactive police forces. To the Guarda Nacional Republicana, while a police force, it must ensure the rights and freedoms of citizens, constitutionally protected by this preventive action, seeking to step up pro-actively its presence in society. However, it is sometimes necessary to use a repressive intervention for the purpose of restore order and seek a future prevention, while avoiding antisocial behavior. It is therefore relevant to study how it articulates preventive and repressive action of the GNR, in order to understand if it is possible to be a balance between them, or if, for some reason, there are limitations on its use. The Destacamento Territorial de Coimbra is the case study. This research, in addition to describe the relationship between the two forms of action, intends to identify what characterizes them as well as their strengths and vulnerabilities. In order to collect the required information it were used document analysis, interviews to the Commander of Destacamento Territorial de Coimbra and the respective commanders of the Postos Territoriais, as well as questionnaires to the military of this units, responsible for the exercise patrolling. Then proceeded to the content analysis of the data collected. The conclusions reached, it is noted that the lack of human resources mainly corresponds to the problem of the Destacamento, so it makes it dificult to continuous patrolling among citizens and enabling the implementation of the Proximity Policing. It also denotes the intense road inspection that despite having a preventive nature, is interpreted by the population with an image of repression.
