En dépit de leur caractère distribué, les chaînes logistiques peuvent se révéler très performantes dans les conditions idéales de production et d’échange. Toutefois, leur complexité les rend de plus en plus fragiles. Cette thèse propose des modèles et des méthodes pour l’analyse des risques, de façon à renforcer la robustesse et la résilience des CLs. Nous avons analysé ce domaine suivant une démarche ontologique à l’aide de la méthode KOD pour tirer les caractéristiques essentielles des CLs. En nous appuyant sur un état de l’art du domaine des risques dans les chaînes logistiques, et sur les bases de cas réels, nous avons identifié les indicateurs des vulnérabilités les plus significatifs. A partir des connaissances extraites, et des modèles mathématiques proposés dans la littérature, nous avons construit un modèle de CL multi-étages à l’aide de modèles ARIMA intégrant l’aspect aléatoire de la demande. Pour adapter ce modèle aux situations de vulnérabilité et de risques, nous avons ajouté des contraintes de capacité et de positivité sur les commandes et sur les stocks. Sous l’effet d’événements dangereux, certaines contraintes du système peuvent être atteintes et par conséquence, son évolution peut s’écarter fortement de la dynamique nominale. Nous avons proposé des indicateurs de vulnérabilités comme des indicateurs de fréquence des retards de livraison, ou de surcoût d’immobilisation de produits. Enfin, l’occurrence d’événements dangereux a été représentée par des scénarios. Nous avons alors obtenu des résultats de simulation sous MATLAB, qui nous ont permis d’évaluer leurs conséquences pour différentes configurations du système. / Despite their distributed nature, these supply chains can be very efficient in the ideal conditions of production and exchange. However, their complexity makes them more fragile. This dissertation proposes models and methods for risk analysis to enhance the robustness and resilience of SCs. We analyzed this area following an ontological approach using the KOD method. Based on state of the art in the field of risk in SCs, and on real cases, we identified the indicators of the most significant vulnerabilities. From the extracted knowledge and mathematical models proposed in the literature, we built the model of a multi-stage SC using ARIMA models incorporating the randomness of the demand. In order to adapt this model to situations of vulnerability and risk, we have added capacity and positivity constraints on orders and inventories. Under the impact of hazardous events or strong disturbances, some constraints of the system can be reached and therefore, its evolution may deviate considerably from the nominal dynamics or even become unstable. We proposed vulnerability indicators such as indicators of the frequency of delivery delays or costs due to the immobilization of products. Finally, scenarios were used to represent the occurrence of dangerous events. We then got simulation results in MATLAB, which allowed us to assess their consequences for different configurations of the system, especially for strong disturbances of information flows and physical flows .

Este trabalho tem como objetivo o desenvolvimento de uma metodologia para a identificação de perigos e avaliação de riscos que possa ser aplicável a qualquer natureza de empresa e em qualquer dimensão, alinhado com os requisitos normativos do principal modelo de gerenciamento de segurança e saúde ocupacional adotado no mundo na atualidade – OHSAS 18001:1999 e que dele seja possível extrair um indicador de desempenho pró-ativo para avaliar o risco ocupacional na rotina organizacional. O que motiva o desenvolvimento dessa metodologia é a dificuldade observada nas empresas de conciliar e prover suas equipes, gerentes e empregados de um instrumento efetivo de gerenciamento de riscos que possa ser utilizado em todos os níveis atendendo simultaneamente aos requisitos de certificação em gestão de segurança e saúde ocupacional. Seu desenvolvimento foi conduzido com base na experiência de implantação de modelos de gestão, na bibliografia consultada e no uso de uma empresa piloto como meio de validação da mesma, além de outras experiências de implantação da metodologia em empresas de diferentes portes e atividade econômica, em paralelo à ação piloto. As experiências de implantação nas diversas empresas foram úteis na consolidação e na melhoria da metodologia, validação como um instrumento eficaz no gerenciamento de riscos ocupacionais, facilidade de integração e alinhamento com outras práticas da gestão ocupacional e geração de um indicador de desempenho que monitora o gerenciamento de riscos ocupacionais em todos os níveis de decisão da organização. / This paper presents a risk assessment methodology development applied to any company size and core business and aligned to OHSAS 18001:1999 normative requests which has being preferentially adopted worldwide as reference to occupational health and safety management. Also the development comprises a proactive risk performance indicator to be used on daily management routine in all organization levels. The risk assessment methodology development is motivated by the difficulties observed on companies which are adopting OHSAS 18001:1999 by providing an effective and easy use tool for occupational risk management to their personnel and managers in all levels. This development is based on acquired experience on implementing and improving management tool systems and models in different companies in Brazil, on consulted bibliography and also by adopting a large company in Brazil as a laboratory to validate the set up approaches to the main concepts as well as its application to other different companies as a mean of consolidate those concepts approaches. Those implementation experiences were useful to consolidate and improve the proposal methodology and to prove that its use as built is an easy, simple, strong and effective occupational risk management tool aligned and integrated to other management practices and organization needs. Beyond that, the methodology does provide to build an occupational risk performance indicator easy to obtain and to use on daily management routine in all organization levels.

This thesis focuses on two fundamental topics, specifically in medical statistics: the modelling of correlated survival datasets and the variable selection of the significant covariates and random effects. In particular, two types of survival data are considered: the classical survival datasets, where subjects are likely to experience only one type of event and the competing risks datasets, where subjects are likely to experience one of several types of event. In Chapter 2, among other topics, we highlight the importance of adding frailty terms on the proposed models in order to account for the association between the survival time and characteristics of subjects/groups. The main novelty of this thesis is to simultaneously select fixed effects and frailty terms through the proposed statistical models for each survival dataset. Chapter 3 covers the analysis of the classical survival dataset through the proposed Cox Proportional Hazard (PH) model. Utilizing a Cox PH frailty model, may increase the dimension of variable components and estimation of the unknown coefficients becomes very challenging. The method proposed for the analysis of classical survival datasets involves simultaneous variable selection on both fixed effects and frailty terms through penalty functions. The benefit of penalty functions is that they identify the non-significant parameters and set them to have a zero effect in the model. Hence, the idea is to 'doubly-penalize' the partial likelihood of the Cox PH frailty model; one penalty for each term. Estimation and selection implemented through Newton-Raphson algorithms, whereas closed iterative forms for the estimation and selection of fixed effects and prediction of frailty terms were obtained. For the selection of frailty terms, penalties imposed on their variances since frailties are random effects. Based on the same idea, we further extend the simultaneous variable selection in the competing risks datasets in Chapter 4, using extended cause-specific frailty models. Two different scenarios are considered for frailty terms; in the first case we consider that frailty terms vary among different types of events (similar to the fixed effects) whereas in the second case we consider shared frailties over all the types of events. Moreover, our 'individual penalization' approach allows for one covariate to be significant for some types of events, in contrast to the frequently used 'group-penalization' where a covariate is entirely removed when it is not significant over all the events. For both proposed methods, simulation studies were conduced and showed that the proposed procedure followed for each analysis works well in simultaneously selecting and estimating significant fixed effects and frailty terms. The proposed methods are also applied to real datasets analysis; Kidney catheter infections, Diabetes Type 2 and Breast Cancer datasets. Association of the survival times and unmeasured characteristics of the subjects was studied as well as a variable selection for fixed effects and frailties implemented successfully.

This thesis applies entropy as a model independent measure to address research questions concerning the dynamics of various financial time series. The thesis consists of three main studies as presented in chapters 3, 4 and 5. Chapters 3 and 4 apply an entropy measure to conduct a bivariate analysis of drawdowns and drawups in foreign exchange rates. Chapter 5 investigates the dynamics of investment strategies of hedge funds using entropy of realised volatility in a conditioning model. In all three studies, methods from information theory are applied in novel ways to financial time series. As Information Theory and its central concept of entropy are not widely used in the economic sciences, a methodology chapter was therefore included in chapter 2 that gives an overview on the theoretical background and statistical features of the entropy measures used in the three main studies. In the first two studies the focus is on mutual information and transfer entropy. Both measures are used to identify dependencies between two exchange rates. The chosen measures generalise, in a well defined manner, correlation and Granger causality. A different entropy measure, the approximate entropy, is used in the third study to analyse the serial structure of S&P realised volatility. The study of drawdowns and drawups has so far been concentrated on their uni- variate characteristics. Encoding the drawdown information of a time series into a time series of discrete values, Chapter 3 uses entropy measures to analyse the correlation and cross correlations of drawdowns and drawups. The method to encode the drawdown information is explained and applied to daily and hourly EUR/USD and GBP/USD exchange rates from 2001 to 2012. For the daily series, we find evidence of dependence among the largest draws (i.e. 5% and 95% quantiles), but it is not as strong as the correlation between the daily returns of the same pair of FX rates. There is also dependence between lead/lagged values of these draws. Similar and stronger findings were found among the hourly data. We further use transfer entropy to examine the spill over and lead-lag information flow between drawup/drawdown of the two exchange rates. Such information flow is indeed detectable in both daily and hourly data. The amount of information transferred is considerably higher for the hourly than the daily data. Both daily and hourly series show clear evidence of information flowing from EUR/USD to GBP/USD and, slightly stronger, in the reverse direction. Robustness tests, using effective transfer entropy, show that the information measured is not due to noise. Chapter 4 uses state space models of volatility to investigate volatility spill overs between exchange rates. Our use of entropy related measures in the investigation of dependencies of two state space series is novel. A set of five daily exchange rates from emerging and developed economies against the dollar over the period 1999 to 2012 is used. We find that among the currency pairs, the co-movement of EUR/USD and CHF/USD volatility states show the strongest observed relationship. With the use of transfer entropy, we find evidence for information flows between the volatility state series of AUD, CAD and BRL.Chapter 5 uses the entropy of S&P realised volatility in detecting changes of volatility regime in order to re-examine the theme of market volatility timing of hedge funds. A one-factor model is used, conditioned on information about the entropy of market volatility, to measure the dynamic of hedge funds equity exposure. On a cross section of around 2500 hedge funds with a focus on the US equity markets we find that, over the period from 2000 to 2014, hedge funds adjust their exposure dynamically in response to changes in volatility regime. This adds to the literature on the volatility timing behaviour of hedge fund manager, but using entropy as a model independent measure of volatility regime. Finally, chapter 6 summarises and concludes with some suggestions for future research.

The diploma thesis "Risks of suicidal behavior among adolescents: Diagnostic, intervention and preventive options" deals with suicidality and suicidal behavior among adolescents in the Czech Republic. The theoretical part of the thesis describes the basic terms of this topic, various approaches and understanding of this issue in the past and in the present. This work also deals with the forms, methods and motives of suicidal behavior. Furthermore it describes the age of adolescence as an independent evolutionary period in the life of man and analyses the risks of this life era. The theoretical part also contains a description of the epidemiology of this phenomenon and possible diagnostic, therapeutic and preventive approaches to suicidal behavior. The empirical part of this thesis describes the research in which the goal was to determine the connection of the increase of suicidal risk and the basic dimension of the personality (using the Freiburg's Personality Inventory), social support (by the Perceived Social Support Scale) and life engagement (through the Life Engagement Test). The research sample contained 99 respondents from the last years of one of Prague's grammar school and two of Prague's vocational schools. The results of this research confirmed the connection between a lowered suicidal...

Materials and Methods: A cross-sectional census study was developed between March and June 2014, using a quantitative approach with descriptive- analytic analysis. The study’s population comprised of 112 nurses working in teams of Family Primary Care Units and Primary Care Health Centers. Those nurses were asked to answer a questionnaire that addressed the socio-demographic information, the professional routine and the occupational violence faced (types, frequency and characteristics of perpetrators). Data were tabulated and analyzed descriptively and inferentially using the SPSS 22.0 software. The significance level was 5%. Results: Most of nurses are female (94.6%), aged between 34-43 years (38.4%), living with a partner (60.7%) and having a weekly workload of 40 hours (90.1 %). The prevalence of violence was 73.2%. Predominantly, occupational violence comprised of verbal violence (67.0%) and psychological harassment (bullying - 27.1%). Patients (81.1%) and caregivers (83.1%) were responsible for verbal violence, whilst the heads of teams (78.3%) and other health professionals (41.7 %) practiced bullying. The risk factors more frequently reported were the lack of safety in the workplace (73.2%) and the aggressive behavior of patients (67%). The occupational violence was not statistically associated with the gender, professional experience, experience at primary health care, weekly working hours, or working shift (p>0.05). The type of violence faced was not either statistically associated with gender, marital status, professional experience, weekly working hours, or working shift (p>0.05). Conclusion: Occupational violence has high prevalence among Brazilian nurses working at primary health care system. Verbal violence is more prevalent and frequently practiced by patients. The lack of safety in the workplace is the main risk factor associated with occupational violence faced by nurses. / Objetivo: Determinar a prevalência e os fatores associados à violência ocupacional contra enfermeiros da atenção primária em saúde. Materiais e Métodos: Estudo censitário descritivo-analítico com abordagem quantitativa desenvolvida entre março e junho de 2014. A população do estudo compreendeu 112 enfermeiros atuantes nas equipes da Unidade Básica de Saúde da Família e dos Centros de Saúde do município de Campina Grande, PB. O instrumento de pesquisa consistiu de um questionário contendo informações sóciodemográficas (sexo, idade e situação conjugal), caracterização profissional (formação, tempo de profissão, carga horária semanal e turno de trabalho) e referente à violência ocupacional: I) frequência; II) tipo de violência (física, verbal, assédio moral e assédio sexual); III) agressor (identificação e sexo); IV) horário da agressão e V) fatores de risco. Os dados foram tabulados e analisados de forma descritiva e inferencial por meio do software SPSS 22.0. O nível de significância adotado foi de 5%. Resultados: A maioria dos enfermeiros é do sexo feminino (94,6%), com idade entre 34 e 43 anos (38,4%), vivem com companheiro (60,7%) e possuem carga horária semanal de 40 horas (90,1%). A prevalência de violência foi de 73,2%, predominando a violência verbal (67,0%) e o assédio moral (27,1%). Na violência verbal, os principais perpetradores foram os pacientes (81,1%) e acompanhantes (83,1%), enquanto que no assédio moral, os agressores foram os chefes (78,3%) e outros profissionais de saúde (41,7%). Os motivos mais reportados foram a falta de segurança no ambiente de trabalho (73,2%) e os pacientes serem violentos (67%). Não se observou associação estatisticamente significante entre sofrer violência com o sexo, o tempo de profissão, tempo de serviço, carga horária semanal e turno de trabalho (p>0,05). Também não foram verificadas diferenças significativas entre o tipo de violência sofrida e o sexo, estado civil, tempo de profissão, carga horária semanal e turno de trabalho (p>0,05). Conclusão: É elevada a prevalência de violência ocupacional entre os enfermeiros brasileiros, predominando a violência verbal. Os agressores são comumente os próprios pacientes e a falta de segurança no ambiente de trabalho foi o principal motivo relatado.

Although this problem can reach everyone, it is emphasized that nursing has three times more likely to experience aggression or abuse in the workplace than other professionals. Objective: This analytical descriptive census study with quantitative approach developed between March and May 2014 with the objective of analyzing the occupational violence against nursing staff in municipal health of Campina Grande/PB. Characterize socio demographic sample, identify the principles types of violence, characterize the aggressors and identify the procedures adopted and the consequences after the violent acts. Methods: The study population comprised all nursing technicians working in 97 teams of the basic unit of family health (BFHU) and 3 health centers (CS) totaling 106 nursing technicians. The research instrument consisted of a valid questionnaire with 27 questions. Data processing was done using Microsoft Excel software-program and SPSS version 22.0 and analyzing by descriptive statistics through presentation of the presence, frequency, percentage, P-Value and RP-Value for discussion of results. Results: The technicians were mostly women (89.6%), aged between 31-40 years (51.0%), living with a partner (60.4%), with 6-10 years of work experience (28.3%). The length of service in primary health care was 6-10 years (43.3%), with a weekly workload of 40 hours (91.4%) in morning and afternoon shifts (93.3%). The technicians reported the occurrence of verbal (84.0%), moral (52.9%), physical (4.8%) and sexual violence (1.0%). The companions of the patients were primarily responsible for the violence. The frequency of violence reports was “4 times or more” in 41.0% of cases (verbal abuse), and violence occurs in the morning and afternoon shifts (46.7%). The most common risk factors were: violent patient (70.4%) and lack of security or police (67.7%). No significant association was found (p> 0.05) between the variables sex, marital status, length of experience in the profession, length of service in primary health care, weekly workload and work shift, and the occurrence and type of violence experienced. Conclusions: We conclude that the main types of verbal violence were caused by escorts and followed by moral violence by colleagues of the same profession. / Introdução: A violência institucional envolvendo profissionais da saúde se constitui em problema de importância mundial.

As obras de desvio de rios para a construção de barragens, embora tenham caráter provisório, são de estrema importância, pois definem como o empreendimento será executado, garantindo segurança à sua construção, dentro de riscos calculados, devendo no entanto ser o mais econômica possível. As estruturas de desvio devem se encaixar no arranjo das estruturas permanentes, podendo ser utilizadas como tal. Este trabalho tem o intuito de apresentar as principais estruturas utilizadas em esquemas de desvio de rios e caracterizar sua utilização e aplicabilidade. Sempre que possível foram apresentados esquemas utilizados na prática ou previstos em projeto, para melhor exemplificar e caracterizar as diversas estruturas e as possíveis soluções para desvio de rios. / Diversion works for dam construction are temporary. Nevertheless, they are extremely important, since they define how the construction is going to be made, and assuring its safety, within calculated risks. But, they have to be as economical as possible. The diversion structures must fit the global arrangement of the project, being in some cases be used as permanent structures. This document has the objective of present the main diversion structures used in diversion works schemes, as well as characterize their utilization and applicability. Whenever possible, it was presented examples of schemes either already used or just previewed on design, to better characterize and exemplify the many structures and possible solutions for river diversion.

As condições do setor eólico internacional em crise e a subsequente instalação de fornecedores no Brasil tem auxiliado no aumento de instalações de Centrais de Geração Eólica (CGE) no Brasil. A quantidade de projetos de detalhamento e implantação de centros geradores de energia eólica cresceram na mesma proporção. Os projetos dos parques eólicos no Brasil são concebidos, projetados, detalhados e implantados por um conjunto de profissionais de diferentes disciplinas e especialidades que, a partir de informações de referência e delimitações do escopo de trabalho, realizam suas atribuições em momentos distintos dentro do ciclo de implantação de um CGE. Durante a concepção, são considerados parâmetros, tais como interferências físicas, especificação de equipamento, estudos básicos, análise da distribuição, transmissão de energia e capacidades de geração de energia elétrica. Durante toda a fase de desenvolvimento do projeto, um dos principais pontos de atenção são as análises de risco do projeto que avalia o andamento do projeto e visa reduzir os riscos de fracasso da empreitada. Caso estes índices sinalizem problemas ou barreiras intransponíveis, as atividades de detalhamento do projeto eólico devem ser interrompidas. Este trabalho tem como objetivo desenvolver uma metodologia que auxilie na análise de riscos de projetos de detalhamento eólico. Esta metodologia auxiliará profissionais menos experientes ou que não atuem no mercado eólico e precisam de subsídios técnicos para elaborar relatórios aos responsáveis pelo planejamento estratégico de futuros empreendimentos eólico. / The crisis of the international wind industry and the subsequent installation of suppliers in Brazil has helped in the increase of the central premises of wind generation (CGE) in Brazil. The amount of detailing projects and deployment of wind energy generating centers grew in proportion. The wind farms projects in Brazil are designed, engineered, detailed and implemented by a group of professionals from different disciplines and specialties, that perform their duties at different times within the cycle development of a CGE using different reference informations and delimitations of scope of work. During design, are considered parameters such as physical interference, equipment specification, basic studies, analysis of the distribution, power transmission and generation capacity of electricity. Throughout the development phase of a project, one of the main points of attention is the project risk analysis that evaluates the progress of the project and aims to reduce the risk of failure of the venture. If these indices to signal problems or insurmountable barriers, detailing the activities of the wind project should be stopped. This work aims to develop a methodology that assists in the analysis of wind power detailed project risks. This methodology will assist less experienced professionals or professionals that are not used to work in the wind energy power market and need more information for reporting technical issues to those responsible for strategic planning of future wind projects.

Sabe-se que enfermeiros que atuam em unidades de internação psiquiátrica, desenvolvem múltiplas tarefas com diferentes graus de exigências e responsabilidades, as quais, dependendo do ambiente e da forma como está planejado e organizado o trabalho podem expor este profissional aos riscos ocupacionais presentes, com conseqüências negativas para a sua saúde bem como, para qualidade do cuidado prestado aos pacientes. Dentre estes riscos, destaca-se os psicossociais. Os riscos psicossociais relacionam-se à aspectos de planejamento, organização e gerenciamento do trabalho que podem provocar desgaste físico e emocional ao trabalhador. Este estudo tem o objetivo de caracterizar os riscos psicossociais relacionados ao trabalho de enfermeiros de um hospital psiquiátrico e as estratégias para o seu gerenciamento. É um estudo descritivo utilizando a abordagem qualitativa dos dados. Os participantes foram 25 enfermeiros inseridos há mais de 6 meses no local de estudo e a coleta de dados foi realizada por meio de entrevistas semiestruturadas no período de novembro à janeiro 2014/15. Para análise dos dados foi utilizado o método de análise temática. O trabalho foi aprovado no CEP da EERP/USP. Os resultados mostraram sete categorias de riscos psicossociais tais como: formação profissional, ambiente e equipamento de trabalho, relacionamento interpessoal, carga e esquema de trabalho, recursos humanos, interface trabalho-família, violência. Não foram identificadas estratégias organizacionais para o gerenciamento dos riscos, entretanto, os enfermeiros relataram a implementação de estratégias individuais para aliviar as tensões e/ou riscos gerados no ambiente de trabalho tais como: recorrer a presença da família, cinema, música, leitura, exercícios físicos, busca por terapias, religião, viagens e passeios. O estudo contribuiu preenchendo lacunas na produção de conhecimento sobre riscos ocupacionais a que estão expostos os profissionais enfermeiros de saúde mental no contexto hospitalar. Além disso, os resultados podem fornecer subsídios para gestores conhecerem detalhadamente as condições de trabalho aos quais estão expostos enfermeiros psiquiátricos, na perspectiva de implementar estratégias preventivas e/ou conservativas no ambiente laboral / It is known that nurses who work in psychiatric inpatient units, develop multiple tasks with different levels of requirements and responsibilities, which, depending on the environment and how it is planned and organized the work can expose these professionals to occupational risks present with negative consequences for their health as well, to quality of care provided to pacientes.Dentre these risks, we highlight the psychosocial. Psychosocial risks are related to aspects of planning, organization and management of work that can cause physical and emotional stress to the worker. This study aims to characterize the psychosocial risks related to the work of nurses in a psychiatric hospital and strategies for its management. It is a descriptive study using a qualitative approach. The participants were 25 nurses inserted for more than six months at the study site and the data collection was carried out through semi-structured interviews in the period from November to January 2014/15. For data analysis we used the method of thematic analysis. The study was approved by CEP- EERP / USP. The results showed seven psychosocial risk categories such as vocational training, environment and work equipment, interpersonal relationships, work load and work schedule, staffing, work-family interface, violence. Organizational strategies for managing the risks have been identified, however, the nurses reported the implementation of individual strategies to ease tensions and / or risks arising in the workplace such as: enlist the presence of the family, cinema, music, reading, exercises physical, search for therapies, religion, travel and tours. The study contributed filling gaps in knowledge production about occupational hazards they are exposed to professional mental health nurses in hospitals. In addition, the results can provide information for managers to know in detail the working conditions to which they are exposed psychiatric nurses with a view to implement preventive strategies and / or conservative in the work environment
