Full textLarge collective threats are intentional and unintentional products of human activities, whose effects form away from the gaze of men unpredictable complexes causing singular dynamics of collective risk. Since the late twentieth century, the great forces of globalized modernity project these dynamics on the entire social and living world. Their prevalence is the result of an exhaust phenomenon off devices supposed to control. The approach of these dynamics through separate disciplines does not allow the reconstitution of their singular trajectories nor their effective processing. We thus propose a common representation of dynamics of collective risk in a multidisciplinary perspective. The thesis examines in particular its manifestations in four key areas of global modernity: finance, nuclear issue, biopolitics and biotechnology

Full textThis Bachelor’s thesis is a literary review of project risk identification. The thesis purpose is to create an idea to its reader of what are projects, risks and how is their identification implemented. The thesis consists of definition of the project and its objectives and character. In addition, the thesis includes definitions of different project organization, division of labour in projects, stakeholders and project’s life cycle. Second part of the thesis consists of risk. It defines the risk, different types of risks and its sources. Major topic in this part is difference between uncertainty and risk. After defining this the thesis handles on project risk management. This management is strongly linked in identifying risks which is the last part of this thesis. In the last part thesis goes through identification techniques and tools which can be applied to all projects. The thesis is focused on defining matters on general level and it doesn’t go deep into case situations. However, there are few visualizing examples in some chapters. All in all, the reader gets competent information about projects and how risks are connected to projects, together with how important is risk identification

Full textHealth is a dynamic and multifactor construction which has both an individual and a social dimension. The latter may have a direct or indirect effect on the behaviour of individuals and their life choices. The Framingham study has revealed that cardiovascular risk is multifactorial and, as such, its estimate should be global. However, the assessment of global cardiovascular risk methods do not take into account the living environment of individuals, which would factor the development of modifiable risk factors. Through this work, we highlight the characteristics of the environment of dissemination of modifiable cardiovascular risk factors: metabolic and behavioural. Since decades, the North region of France has, for cardiovascular diseases, a high level of global and premature mortality. We are asked about the determinants of the situation of this region, by comparing it to other French regions and by exploring the link between a high cardiovascular risk and an unfavourable economic situation. Thus, we are interested in the link between the distribution of cardiovascular risk and the distribution of income, using normative criteria based on the concept of expected social dominance in terms of poverty. Shedding a light on factors favouring the occurrence of cardiovascular problems and analyzing the knowledge about the individual’s life environment allows a better understanding of the mechanisms of diffusion of the modifiable risk factors, with a double objective to lower the incidence and prevalence of cardiovascular diseases and to reduce the social inequalities in health

Full textThe problematic of this thesis is the impact of accounting information on the risk or failure and on the market risk form firms. We have showed that the financial theory is not unified about the risk of failure. We have improved the prediction of failure risk with expert system and with a new building method of discrimination model. The expert system detects some accounting handing. Therefore the statistical analysis is more reliable with the expert system. The improvement of discrimination model is the use of step by step building under two constraints (statistical and financial constraints). The risk of failure rating includes the sectorial activity and the last accounting innovation (The cash flow of R. Dornier). The model is conceived with 901 firms and tested with 5000 balance sheets belonging to SNVB customers. For firms rating on the stock exchange, we have successively realised an analytical and empirical approach to apprehend the impact of accounting information on the market risk. We pointed out in two theorical models that the evaluation of market risk may be improved by accounting variables such as the firm growth. Finally, we have showed, on a small sample (155 cases) that the impact of accounting information may be improved by mathematical fonction of jump on the share returns distributions

Full textInternational literature on paramedics reports a prevalence of obesity, cardiovascular diseases and post-traumatic stress disorder. Furthermore, in Quebec, paramedics have a high rate of debilitating work injuries as well as an important rate of early retirement for disability compared to the average of other emergency workers. The aim of this thesis was to explore the issue of occupational stress and theirs consequences among paramedics working in Quebec and using the activity model by Guerin et al. (1997). To achieve this, we conducted a questionnaire study, a laboratory study and a field study. The questionnaire was used to determine the presence or absence of psychosocial constraints and cardiovascular risk among 205 paramedics. The laboratory study allowed us to investigate the physical condition in 31 paramedics. As for the field study, it provided a better understanding of paramedics’ eating habits while at work in 40 paramedics. The main results from are: a lack of social support and an effort-reward imbalance, a prevalence of obesity that tends to increase over time, low cardiovascular condition which tends to decrease rapidly for night workers compared to day workers, good muscular strength, smoking. Also, we have demonstrated causal links between lack of support from hierarchy, a large consumption of tobacco, emotional eating desinhibition and increased body mass index during employment. The findings show that paramedics combine several risk factors for cardiovascular disease during their careers. In conclusion, it is important to emphasize the absolute need to develop primary interventions with both companies and paramedics.

Full textVenture capital is a financial innovation which is devoted to intermediate equity financing for start-up and development of innovative firms. This doctoral thesis, which is a contribution to the research on venture capital as financing source, is also an attempt for a reinstatement of financing processes in the analysis of regional development problems. Formation and development of the French venture capital system are studied with a privileged look out for its regional patterns. The regional venture capital faces the very strong constraints of venture capital (information asymmetries, agency problems, illiquidity of shares) through the advantages of proximity; nevertheless, it is, in compensation, subject to the constraints of territorialisation. Thus, despite the increase of the number of regional funds, the French venture capital market appears still strongly centralized and characterized by significant interregional disparities

There are numerous examples of extreme operational losses and their amounts are threatening for the financial system stability. All the same, high-frequency and low-severity losses represent a major defy facing financial institutions. In order to minimize the exposition to operational risk and reduce its losses, the Basel committee on banking supersivion, in its new agreement "Basel II", invited banks to develop their own management and measure model over this risk. We shall propose in this thesis a model of operational risk quantifying by integrating data both internal and external to the bank. This model is built upon four calculation methods. It takes into account the various managerial and quantitative aspects of operation risk. The theory of extreme values consists in analysing tails of probabilities distribution, the loss approach distribution is interested in explaining losses behaviour, the measure of residual risk is a global calculation method of operational risk which puts in relation the different bank risks. The method of data envelopment analysis puts in evidence the bank's internal management quality

Full textChapter one examines the long run statistical characteristics of financial returns in France and the USA for selected assets. This study clearly shows that the returns’ distributions diverge from the Gaussian strategy as regards longholding periods. Thereafter we analyze the consequences of the non-Gaussian nature of stock returns on default-option retirement plans.Chapter two provides a reasonable explanation to the strong debate on the Efficient Market Hypothesis. The cause of the debate is often attributed to small sample sizes in combination with statistical tests for mean reversion that lackpower. In order to bypass this problem, we use the approach developed by Campbell and Viceira (2005) who have settled a vectorial autoregressive methodology (VAR) to measure the mean reversion of asset returns.The third chapter evaluates the speed of convergence of stock prices. A convenient way to characterize the speed of mean reversion is the half-life. Comparing the stock indexes of four developed countries (US, UK, France and Japan) during the period 1950-2014, we establish significant mean reversion, with a half-life lying between 4,0 and 5,8 years.The final chapter provides some results from a model built in order to study the linked impacts of demography and economy on the French pension scheme. In order to reveal the risks that are contained in pension fund investment, we use a Trending Ornstein-Uhlenbeck process instead of the typical GBM for modeling stock returns. We find that funded scheme returns, net of management fees, are slightly lower thanthe PAYG internal rate of return

Full textGiven that the growth prospects of developed countries rely heavily on their ability to develop innovation, the issue of financing innovation is crucial. Biotechnologies are the center of many debates and are described as a source of growth and jobs for our modern economies. Companies specializing in biotechnology encounter many difficulties in accessing funding. It seems that venture capitalists are one of the few investors that are willing to bear the risks related to the business of biotechnology companies, among which it is necessary to distinguish between independent venture capitalists (IVC) and corporate venture capitalists (CVC). The main objective of this thesis is to analyze the contributions of these venture capitalists in the context of biotechnology and particularly the contribution of a co-investment involving both types of investors. As a first step, we are interested in the study of differences between IVC and CVC. This study is based on the results of a survey of venture capitalists and corporate funding. Given the ability of IVC and CVC to create value, we develop in a second step, a theoretical model that describes the conditions under which a co-investment involving both types of venture capitalists is much more plausible than any other investment strategy, i.e. a stand-alone investment. Finally, we try to check if our main hypothesis, i.e. greater value-adding capacity of mixed syndications, is valued by public markets at the time of IPO and during the two years following that event

Full textIt is recognized in economic theory that the existence of significant risks can cause serious disruption to the well-being of households and to the State budget’s balance, because the risks do not often value for money. Assuming that the risk is a hazard and vulnerability occurs, we find that the hazard is often seen in Niger as the only "guilty" of these disturbances, while the agents' behavior towards risk can be a factor. On this observation, this thesis proposes to analyze these behaviors and their implications in the economic decisions of households. The main results first show a rather relative risk aversion, which can be explained by two main approaches: a fatalistic perception of natural and man-made hazards on the one hand, and adaptive rationality in terms of the importance of these risks and the vulnerability of households, on the other. This notion of aversion was then used to provide a link to the analysis of risk behavior associated with information asymmetry. It is clear from this analysis, to natural hazards which individuals appear powerless; they are developing opportunistic behavior at the expense of credit agreements mutually beneficial, by abuse of informational rent. We believe that in this case, the incentive constraint must be taken seriously. The simultaneity of climate risk and high information asymmetry rural index suggests that the agricultural insurance should be progressively considered

Full textAge-related macular degeneration (AMD) is the leading cause of blindness in industrialized countries. AMD is a complex and multifactorial disease with major consequences on the quality of life. Numerous genetic and non-genetic risk factors play an important role in the pathogenesis of the advanced stages of AMD. Existing prediction models rely on a restricted set of risk factors and are still not widely used in the clinical routine.The first objective of this work was to identify new circulating biomarkers of AMD’s risk using a lipidomics approach. Based on a post-mortem study, we identified the most predictive circulating lipids of retinal content in omega-3 polyunsaturated fatty acids (w-3 PUFAs). We combined penalization and dimension reduction to establish a prediction model based on plasma concentration of 7 cholesteryl ester species. We further validated this model on case-control and interventional studies. These biomarkers could help identify individuals at high risk of AMD who could be supplemented with w-3 PUFAs.The second objective of this thesis was to develop a prediction model for advanced AMD. This model incorporated a wide set of phenotypic, genotypic and lifestyle risk factors. An originality of our work was to use a penalized regression method – a machine learning algorithm – in a survival framework to handle multicollinearities among the risk factors. We also accounted for interval censoring and the competing risk of death by using an illness-death model. Our model was then validated on an independent population-based cohort.It would be interesting to integrate the circulating biomarkers identified in the lipidomics study to our prediction model and to further validate it on other external cohorts. This prediction model can be used for patient selection in clinical trials to increase their efficiency and paves the way towards making precision medicine for AMD patients a reality in the near future

Full textResearch on the association between the experience of trauma and suicidality has been a growing field in the literature since two decades. The current dissertation was originally aimed at identifying sufficient or necessary conditions of suicidality outcomes among individuals exposed to trauma. A procedure of association rule extraction was implemented on a database from of a French national survey. Considering lack of sufficient or necessary conditions of suicidality outcomes, two other suicidality related issues were addressed. The first study focuses on the evidence-based ordering of the suicidality profiles and the detection of symptoms that moderate suicidality levels. Using ‘past month suicide attempt’ as the criterion, three suicidality levels were established. All suicidality levels were systematically moderated by the chronic anxiety symptom. The second study aimed at testing the robustness of the association between the trauma levels and the frequency of past month suicide attempt by identification of the symptoms moderating the incidence of outcome in every trauma level. Seven symptoms regarding desire for death, self-harm intention, suicidal ideation, lifetime suicide attempt, depressed mood, loss of interest, and panic attack exhibited a moderating effect with the fan-shaped pattern. A comprehensive review of the literature revealed the difficulty to obtain an overall picture of the investigated outcomes and their risk factors in the trauma-suicidality background. The third study puts forward a graphical platform aimed at recapitulating the evidence found by 26 studies concerning 20 risk factors of six suicidality outcomes among traumatized individuals. The main risk factors are major depression, and post-traumatic stress disorder. This review highlighted the importance of a common descriptive framework and the availability of the databases collected in previous studies

Full textThe PhD dissertation studies meteorological and economic hazard under different angles and mostly in developing countries. It is composed of three independent chapters analyzing different situations dealing with meteorological and climatic or economic hazard correlation. It estimates the potential of the studied regions for implementing an insurance scheme for the risk. Indeed, this thesis studies risks very likely to be highly correlated: whether this is for the meteorological or climatic hazard, or the price volatility risk, neighbored cities or even countries are exposed to the same risk simultaneously. This essential aspect jeopardizes risk mutualization, a key parameter of the economic insurance model. Through the three chapters of this thesis, we study the benefits linked to the mutualization of a priori correlated risks. The first chapter deals with maize price correlation in Tanzania. Using a Copula-GARCH model, we model the dependence among the 20 main markets of the country and assess if the mean maize price is smoothed by aggregating the markets. Hence, we see whether markets integration allows an efficient risk mutualization against the risk of price volatility. The second chapter deals with tropical storms risk in the South Pacific islands and their impact on infrastructures. This paper proposes an artificial tropical cyclones modeling in the region studied as well as the probability distribution of the cyclone’s occurrence and strength. This enables us accounting for the current climate for modeling costs. With data on infrastructures, we calculate the cost due to tropical storms, including for very low probability extreme events. The third chapter proposes an extension for a statistical emulator of crop yields depending climatic variables. We model the marginal impact of an increase of temperature, precipitations and CO2 concentration by running a statistical estimation on crop models rather than historical data. It allows accounting for extreme effects caused by meteorological data values not observed so far. The model robustness is assessed, among others, with copulas to compare the spatial dependence between the model and our statistical emulator and check that our estimation captures the geographic dependence

Full textThe notion of risk is doubly uncertain: it contains an irreducible part of hazard as its realization in damage on the one hand, and its lack of definition by the law on the other. However, this gap is at odds, both with the exponential use of the notion of risk in criminal law, whether substantive or form, and with the principle of legality of offences and sentences, which implies that the legislator defines clearly and precisely the notions and concepts to which it refers. That is the reason why the legitimacy of the use of the notion of risk in criminal law can be questionable. The presence of such an uncertain notion in a field involving the fundamental rights of the person is likely to jeopardize the imperatives of the State of laws. Moreover, the criminal law of anticipation, which aims to prevent the occurrence of possible but uncertain interference with a protected right, is criticized. The purpose of this demonstration is therefore to know whether or not the legislature uses wisely the notion of risk in criminal law. The answer to this issue will previously require to ensure that criminal law is actually legitimate to focus on the notion of risk. This is not because the legislature takes into account a notion that its account is necessarily legitimate. Moreover, it is important to keep in mind that risk and the criminal law are inherently contradictory: the risk is uncertain, immaterial and is linked to the concept of prevention while the criminal law is the right of repression, the materiality and the certainty. A deep study of their respective natures will nevertheless make it possible to overcome the contradiction, stating that the criminal law is theoretically legitimate to accept the notion of risk. This legitimacy stays nonetheless quite precarious. To secure this legitimacy, only a certain kind of risk, a risk with a managed level can be taken into account. If the legislator claims using the notion of risk in criminal law for anticipated criminal protection of society, he still cannot ignore the principles that are applicable in criminal law. From the study of the fundamental principles of criminal law, its legal concepts and its supralegislatives sources, this research will then offer a definition of the notion of risk in criminal law, containing the theoretical criteria of a legitimate criminally detectable risk. Its comparison with positive law, will emphasize whether the use of the notion of risk by the legislator in criminal law, makes him lose or not its legitimacy

Full textIn risk theory, the main task of the actuary is to manage the risks underwritten by the company so that, at any time, it will be able to fulfill its obligations. Risk measures are valuable tools for this purpose. In this thesis, risk measures and capital allocation methods based on the dependence between multivariate risks are studied. Also, new measures of risk and capital allocation methods are developed within the framework of multivariate portfolios with partially aggregated dependencies between risks. The introduction presents a literature review and the concepts discussed in this thesis. In the second chapter, the capital allocation based on the measure Tail Value-at- Risk (TVaR) for a portfolio of risks following multivariate distributions with continuous severities is presented. The third chapter is the study of the bivariate Value-at-Risk (VaR). The latter is studied and illustrated, according to the dependence between risks. Several results on the conditions of convexity and relative to concordance orders and bounds of this metric are set. An interesting application in insurance is also presented. The new bivariate lower and upper orthant TVaR are presented in chapter four. These measures are motivated, studied and applied to Equity Indexed Annuities associated with correlated assets. The fifth chapter presents a numerical algorithm in order to calculate lower and upper bounds for sums of random variables. The method suggested is concise and parsimonious. It also allows to compute bounds for the VaR for sums of random variables. A brief conclusion recalls the contributions of this thesis and suggests some interesting research venues in connection with topics discussed in the previous chapters.

Full textA common interpretation considers Plato as a supporter of an ideal policy, giving no credit to economics. If an economy can only be liberal, without any form of political control, then maybe such an interpretation makes sense. But here's the pitfall: is economic liberalism the epitome of all economies? Plato does not disregard economics at all. On the contrary, this work shows that he should be considered as a founder of political economics. He was the very first to identify the economy as a risk for the city and yet, at the same time, he acknowledged that this risk had to be run. Thus, his political thought, far from disregarding the economy, has an ever-present bond with it. The first part goes back to the origin of philosophy. Philosophy has always been held as a disinterested activity. Yet it emerged at an ambiguous time when trading prevailed among men. In order to avoid any confusion with the sophists, who claimed that the logos had an economic value, Plato soon defined his own theory of value, influenced by Socrates and traditional views. The second part shows how this theory became the ideological background of the Callipolis. The city stems from need and the necessity for an economy. Plato immediately saw its conflicting nature and its link to history. Modelling his city on a natural organism, he left nothing unattended in order to prevent this risk. Yet, some theoretical impasses and personal disappointments led him to alter his views. The third part thus explains how Plato revised his plans in a more realistic way, with his idea of mastering the economic disorder still in mind. One can then see how much the Laws are to be read as a real political economy. With an acute sense of details, Plato builds again a city in which every element, from town-planning to laws on worship, has an economic ground

Full textThis thesis deals with the topic of venture capital and the funding of young innovative companies. Venture capital markets play a key role in funding innovative projects. Venture capitalists are investors that specialize in providing funds to highly innovative firms with risky prospects. These firms can be high growth firms that are the source of a sustained job creation. I study the mechanisms that contribute to the success of venture capital markets and their impact on the funding of innovative projects. A matching model between venture capitalists and entrepreneurs implementing innovative projects helps us understand the role played by the venture capitalist’s expertise in the success of innovative projects and in the efficiency of venture capital markets. I present also an endogenous growth model where the efficiency of the matching process between venture capitalists and entrepreneurs has a direct impact on the growth rate. I analyze the impact of adverse selection on the funding of innovative projects by venture capital. Which projects are funded by venture capitalists? If venture capitalists fund only high quality projects, is there a role for government intervention? I finally investigate which role can be played by public intervention in order to encourage the development of active venture capital markets

Full textType 2 diabetes is a risk factor for dementia, but no benefit of intensive glycaemic control has been identified so far. We explored several potential reasons for those conflicting findings. First, as diabetes is a major cause of mortality, we estimated the diabetes-associated risk of dementia considering the competing risk of death, in a population-based cohort of French older adults. Diabetes was associated with a higher dementia risk and a 2-to-3-year lower dementia-free life expectancy; no effect modification was shown. These results confirm the potential impact of diabetes prevention and treatment in reducing dementia risk. Second, we estimated the mediating effect of several brain biomarkers in the association of diabetes with cognitive status. We found that (1) brain atrophy and cerebrovascular lesions had a significant and independent mediating effect in the diabetes-dementia association in community-dwelling older adults, and (2) the association of diabetes with lower cognition was significantly mediated by higher neurodegeneration, independently of cerebrovascular lesions and Alzheimer’s disease biomarkers. These consistent results suggest the importance of the direct effect of diabetes on neurodegeneration. Diabetes-associated metabolic alterations that may explain this association should be explored

Full textAt present, the question of seismic modelling is still very open. The work reported in this document proposes a modelling of the whole of the chain, from the description of the initialization of the earth tremor until the damage of the reinforced concrete structure, while passing by the transmission of the wave through the ground, the goal being to implement a robust approach of the damage structure. A decoupling of the various phenomena is introduced, in order to work on simplified models on each level. To start, an original model of seismic fault is developed, the 3S model. The wave propagation is then studied by regarding the ground as a stratified medium. Lastly, uncertainties are taken into account in the evaluation of the damage of the structures. Specific methods of convex analysis are then implemented

Full textThe legislation devoted to the occupational. Hazard (health and safety at work, industrial accidents) currently passes through. A crisis of effectiveness and identity, which invites to, draw up a positive and critical, state of this legislation. The aim of this thesis is to, draw up this state, in a spirit of objectivity and on the bases of a distinction between the problems of acknowledgment (how to improve the acknowledgment of the risks related to the working conditions) and attribution (what justifies that certain risks are attributed to, the employers of the people concerned). It tends to define the conditions favourable to the development of a rational policy of prevention and compensation concerning the occupational hazards : first, the creation of a unified legal category of "occupational hazard", with which would be associated a mode of acknowledgment characterized by a coherent distribution of powers and, duties between the authorities, experts and the concerned people ; secondly, the identification of the main functions assigned to the legal status of the occupational hazard (prevention of risks, sharing of the compensation charges), in order to draw limits of this status in a more precise way, as well for the potential victims ("workers") as for the designated persons in charge ("employers")

Full textFrom a legal point of view, the term 'risk', which is not defined in the Civil code, refers to an unpredictable, future and harmful event. There are nevertheless different variants in the definition of the term. Its concept is plurivalent since it can have several meanings in civil law. As a result, the notion of 'risk' can be understood in a synchronic, circumstantial way, by changing the context of the criteria characterising said notion. The meaning of the notion of 'risk' also varies with time, as law faces new issues. Each of these variants is likely to affect the law. Due to its various meanings, it becomes specific. The notion of 'risk' is complex and provides one of the essential elements in civil law. It is therefore a fundamental concept of civil law

Full textPolypharmacy is defined as the administration of many drugs at the same time or as the administration of an excessive number of drugs. The main objective of this thesis was to describe chronic polypharmacy and the associated risk, from medico-administrative databases. A specific indicator of chronic polypharmacy, defined by five or more concomitant and chronic drug uses, was developed to describe the prevalence and the involved drugs. Based on data from the National French Health Insurance, we estimated that chronic polypharmacy concerned more than 5% of all aged French individuals, and involved mainly cardiovascular drugs. To further describe chronic polypharmacy, a description of inappropriateness was carried out using data from the National French Health Insurance and the United States Veterans Health Administration. We estimated that the inappropriateness of chronic polypharmacy was major. It concerned 65% of French older adults (≥ 65 years old), 46% of French middle-aged adults (45-64 years old) in France, and 67% of American veterans. Proton pump inhibitors, psychiatric drugs and diabetes drugs were the most common potentially inappropriate medications. Furthermore, we have shown that chronic polypharmacy, whether appropriate or not, is associated with increased mortality. In American veterans, chronic polypharmacy and potentially inappropriate medications both increased the risk of all-cause death

Full textThree situations are studied in the field of fund management where investment risk may be misperceived due to an ambiguity in the way risk is being measured. The case studies involve equity, bonds and currencies respectively, and are inscribed in the traditional conventions of finance theory. It is shown how the perception of risk can fail immediately in the initial data processing stage even before a propoer analysis. Several risk measures that are frequently used in finance are shown to be defunct or badly adapted for the circumstances in which they tend to be used. We described how in certain cases sub-optimal investment decisions are taken based on an error in measurement, or how in certain cases the debate in the economic literature has been disorientated. The studies underline that the appreciation of financial risk is far from trivial, even in the realms that are generally considered as well-established
